2019 HYUNDAI TUCSON Engine Problems

Engine failure will be caused by shrapnel in the engine (Dealer told me Hyundai is aware it was not vacuumed out properly in this particular batch of engines) leading to ruts being warn in the cylinder causing oil to leak past piston rings. Loses so much oil quickly. Extended warranty may deny due to 3 missed air filter changes

I took my vehicle to my mechanic for inspection check up. My mechanic told me and supplied paperwork from their scans that the P0420 sensor in the cat converter was shot again (3x in 5 years) and needed to be replaced. The engine light had come on 3 weeks beforehand and I had it read and knew what it was. They sent me to Hyundai dealer as it was under warranty with documentation. I get to Hyundai dealer tell them it needs the sensor for inspection and an investigation for oil leaking from back of the engine. I also told them I was adding 2-3 quarts of oil between oil changes. They told me my mechanic over filled oil by .5 quarts and that's why the engine leaked. They investigated after I disputed by saying an oil change had been performed the day I brought it to them and found...

The contact owns a 2019 Hyundai Tucson. The contact stated that while driving on the highway at 70 MPH when the vehicle acceleration speed was reduced to 40 MPH independently. The check engine warning light had illuminated. The vehicle was taken to a local dealer where it was diagnosed that the gasket fuel pump, camshaft, timing chain, timing chain sensor, and intake cam were faulty and would need to be replaced. The vehicle was repaired, however, the failure persisted. The manufacturer was not notified of the failure. The approximate failure mileage was 105,000

2019 Tuscon with 70k miles.Engine failure, had to have vehicle towed to dealership. I have been without a vehicle for over a month and other than the dealership leaving me a message saying that my engine is seized, I have been completely ignored.

While driving on the highway, the check engine line came on and my Tucson started loosing power. I quickly moved into the right lane and was able to exit the highway and pulled over. I had previous issues with the vehicle and was told it was the 1 & 2 ignition coils that were replaced. I assumed it was the same issue for the 3 & 4 ignition coils. They were also replaced but the issue was not resolved and the vehicle was towed to a mechanic shop who stated there was a piece missing off one of the pistons and he couldn't determine how that could have occurred. At this point, he said my engine would need to be replaced and apparently they are back-ordered for 6 months. My daughters vehicle - 2019 Kona, was purchased at the same time and she also lost power in her engine while...

Knock sensor keeps throwing codes, the car will not accelerate over 20mph and under 2000 rpms

My car lost power and was shaking while driving, the dealership service department told me that that my car was producing a code for a misfire in my exhaust valve chamber #3 and I could replace this for $4400 but in a few months I would need a new engine so they recommended I replace the engine for $8000. I am 1000 miles over my warranty so Hyundai is refusing to pay for this. I currently finance my car and owe $22000 on it still and can not afford to fix my car out of pocket. My car has been at the service department since 9/6/2024, I’ve researched this problem with this make and model and thousands of Hyundai owners are being denied for new engines because the engine failure was not caused by the rod bearings, ultimately both of these concerns and problems are cause from oil consumption and...

Engine stalled while on the road with no warning lights. Seized and doesn’t start. Hyundai said that that it was engine neglect because of sludge yet we consistently got the oil change.

I have had to replace the exhaust manifold and catalytic converter twice since owning my car. I have owned my car since 2020 and bought it at 23,000 miles. The car now has 100,000 miles - all highway. The code P0240 has displayed again and the dealership said I need to replace the catalytic converter and manifold for a third time. The car burns synthetic oil very quickly as well. Dealership has found no leaks of oil. I have to change oil every month because of how quickly the oil burns. I have conducted my own research and have found several other owners of 2019 Hyundai Tucson are having similar issues. I encourage Hyundai and its partners to initiate an investigation. This could cause detrimental damage to the engine. Something is wrong!

- replaced catalytic convertor twice - Check engine light on , needs another catalytic convertor - Exhaust fumes are coming back into my car through the AC vents , I’ve had to pull over due to being nauseas and extremely dizzy. - The dealership will not answer my phone calls , but will answer another phone because I have called from another phone and they picked up immediately - Was told from a service advisor that they would not help me “ unless the car blew up “ - My car did recently ,8/8/24, shake aggressively, the check engine light flicked rapidly and a strong puff of fumes came through my car - They will not help me because they stated that my rod bearings are not rotted therefore I do not qualify for assistance and everything would come out of pocket , the engine replacement , the catalytic convertor...

The contact owns a 2019 Hyundai Tucson. The contact stated while driving at an undisclosed speed, the check engine warning light illuminated, and the vehicle lost motive power. The vehicle was towed to the dealer where the vehicle was diagnosed with catalytic converter failure and sludge in the engine oil. The contact was informed that the engine needed to be replaced. The catalytic converter was replaced. The vehicle was not repaired. The vehicle was towed to the residence. The contact stated that the vehicle was at the dealer for 55 days. The manufacturer was made aware of the failure and a case was filed. The contact was informed that the engine was not covered under warranty. The contact was informed that because the history of the oil changes was consistent with Hyundai, the engine was not covered under warranty. The failure mileage was approximately 70,000.

formance exhaust. I bought catalytic conVerter that they told me to buy for 600+ dollars and took it to child's shop they told me that the catalytic converter isnt clogged nor is it affecting my car and provided me with these codes about the camshaft and crankshaft (P0017,P000B, P000A) which they stated hyundai should have fixed under the engine warranty because it was a recall on these engines on this year car. They stated that even if fixed the converter my car would still perform the same and 3 other mechanics have said the same and stated hyundai would have to fix it. After oil changes the oil consumption in my car is constantly getting oil before its even due for another oil change. I have already paid so much just by having people look at it, buying oil, parts, and etc. i am furious to know that i was...

The check engine light came on and then started flashing. It was 3 quarts low on oil and there were still 1,000 miles left before the next oil change. The oil has been changed regularly since we purchased the Tucson in December 2023. A mechanic looked at the vehicle today and said metal shavings were in the oil and the engine needed replacing. The 2019 Hyundai Tucson got good reviews and was considered a safe vehicle for teen drivers, but now I'm wishing we purchased something else for our kids to drive.

See attached document for complaint

’ve replaced the catalytic converter two times , the check engine light is on so it says I need another catalytic converter, that was in June 2024. The car was at the shop yesterday, needs catalytic converter and oil is pooling all throughout the car , fumes from the exhaust are coming back into the car which makes me physically ill. The engine revs and slows down by itself, it goes through oil on such a regular basis that I have to carry a full size jug of oil with me at all times because I need to put it in before I leave work and when I am on my way back home , the dipstick will be dry.

The contact owns a 2019 Hyundai Tucson. The contact stated while driving 50 MPH, the vehicle lost motive power. The check engine warning light was illuminated. The contact was able to pull to the side of the road. The contact stated that upon turning off and restarting the vehicle, the check engine warning light remained illuminated. The contact activated the hazard lights and drove to the residence. The vehicle was taken to the dealer, where it was diagnosed with a possible knock sensor failure. The vehicle was not repaired. The manufacturer was notified of the failure and a case was opened. The manufacturer later informed the contact that the VIN was not covered under an unknown recall. The failure mileage was approximately 76,000.

The drain plug was loose, even thought the mechanics ensured it was tightened. This is another case out of many of 2019 Hyundai Tucson owners who have found the drain plug to be faulty causing loosening and then falling out causing all oil to drain quickly and without warning. My engine unfortunately died mid drive while at the base of a large bridge, causing safety risks to myself and my passenger, as well as other drivers on the road. The engine lost so much oil at once giving no chance to even be warned about malfunction, as we were driving and it just fell out. My engine seized completely. This is not the first time Hyundai parts have done this, according to other owners, mechanics and other forums. Hyundai still has no recall for this faulty parts and offers no assistance to remedy a potentially life threatening situation.

The contact owns a 2019 Hyundai Tucson. The contact stated that while driving at 5 MPH, the vehicle slowed down. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the knock sensor needed to be replaced. The vehicle was repaired, but the failure recurred. While driving, a month later, the vehicle slowed down. The vehicle was taken back to the local dealer, where it was diagnosed that the knock sensor needed to be replaced. The vehicle was repaired, but the failure persisted. The vehicle was taken back to the local dealer, where it was diagnosed that the engine needed to be replaced. The engine was replaced. Additionally, while driving, an unknown vehicle crashed into the rear of the vehicle, and it continued to move forward. The steering wheel became stuck and was uncontrollable. The driver shifted the gears to park...

The car barely has 50,000 miles on it and I had to replace all the tires rotors and brakes. Then a week later we were driving and it started making a funny noise and it would not drive more then 30 mph. I am going to have it towed to the dealership and see what the problem is. I have been reading about a lot of people with this same problem for faulty engine. I will sue them if this is the case this happened another time to me and I sued them under the lemon law

My car is burning oil like crazy, having to top off engine with 1.5 quarts between 5,000 mile oil change with synthetic oil. Took to Hyundai for oil consumption test. Let them know I'm having issues with burning oil, and my check engine light comes on often. They looked at my car saw enough of a problem according to advisor to skip first step of oil consumption test and jump straight to step 2 an engine combustion cleaning, which cause multiple more codes to come on. Drove the 1,000 mile 1378 to be exact because I explained to them that I couldn't bring back at exact mileage and was told that was fine. I was toldy car was only a quart low and that that meant everything was fine and that they would now honor the warranty. I am using in ungodly amount of gas and my engine oil smells...

The Engine start having a knocking sound, it got worse until stop, it burned the oil faster.

The contact owns a 2019 Hyundai Tucson. The contact stated that upon starting the vehicle, he observed unusual RPM fluctuations and vibrations during idle, after which the check engine warning light illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the catalytic converter. The vehicle was not repaired, and the contact continued to drive the vehicle. The vehicle was later taken to an independent mechanic, who determined that there was a misfire in cylinder #4. The independent mechanic informed the contact that the failure was previously misdiagnosed, resulting in damages to the engine and that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 100,000.

I was driving approx 55mph on [XXX] in my 2019 hyundai tucson when the check engine light came on and the engine started to stall. I felt the acceleration dying down in the middle of busy highway traffic. Gray smoke started coming from the hood cracks. I luckily was in the right lane already, so when I could I veered off to the shoulder and the car quit. The smoke was increasing badly. Ppl from the highway were yelling its going to blow up get away from it! I was so scared. I grabbed my phone and keys and ran as far as I could while dialing 911. Within a couple minutes flames were swallowing the entire engine and front of the car. I am furious. I researched online and hyundai has had many similar incidents with this car and other with this engine ! These need to be banned...

Engine failure Needed to be replaced just over 52,000 miles

Engine failure. Car suddenly stop and engine light lit on.

On 05/11/2024, I accelerated onto the freeway at which point my vehicle would no longer go past 50 mph with the pedal to the floor. I had my two small children in the car at the time. It was dangerous as cars around us were going 65+ mph. The check engine light started blinking when this was occurring. Prior to that the check engine light had been on because the dealership claimed they didn’t know why it was triggering and that they have to take my engine out and replace it just to explore the issue. I don’t have the money for that. It has a knocking sound, a pungent fuel smell and it still won’t accelerate. I only have 85k miles on the car.

I was driving on the highway when my vehicle started decelerating and shutting down completely. I ended up safely pulling over because it could’ve been a serious accident and called FHP they tested my car code p1326 came up I had it towed to the dealership where they assured me I had the extended warranty and that the car should be covered and I don’t have to pay out of pocket. What the dealership told me would take 2 days has now been almost a month and still counting. I’ve had 3 denials for engine replacement due to being outside of warranty with Hyundai even though I have the extended warranty. The dealership has sent pictures and spoke with my case manager at Hyundai to confirm that the engine failure was due to the bent connecting rod bearing that is again covered under warranty. They came back and said other...

The contact owns a 2019 Hyundai Tucson. The contact stated while driving approximately 40–45 MPH, the vehicle failed to accelerate as needed. The vehicle failed to accelerate about 35 MPH. The vehicle went into LIMP/SAFE Mode. The check engine warning light was blinking. The vehicle was towed to an independent mechanic and the contact was informed that the failure was due to metal shavings being in the oil. The contact called the local dealer and was informed that there was no recall coverage on the vehicle. The dealer informed the contact about diagnostic testing the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was contacted and opened a case. The contact was informed that the vehicle was not covered under recall. The contact related the failure to NHTSA Campaign Number: 20V543000 (Service Brakes, Hydraulic). The failure mileage was approximately 92,000.

The components that failed are the engine and transmission and parts associated with the functionality of these parts. It is currently in the shop but will be available for inspection upon request once repairs are complete. My safety and others were put at risk when these malfunctions occurred (driving incredibly slow on the highway could cause an accident, accelerator malfunctioning that might break, broken down late at night hours from home, parts catching fire from leaking oil, etc.). The problems have been acknowledged by my warranty company and the two repair shops that have serviced it. My car was inspected by Geico Insurance Company after I got rear-ended and needed to file a claim, however, the inspection was not specifically on my engine/transmission. The warning dash lights didn’t seem to come on until it was too late, especially during the transmission issue. I was driving around for days leading up...

I have to add oil to my every 2 days.. there is no leaks and I get frequent oil changes. Also acceleration to meet state limits my Rpm go super high not wanting to shift. Again no leaks and have checked so there is good transmission fluid in it

Check engine light comes on it has come more then 5 times. I take it to the dealership. They tell me they are doing an oil consumption test this makes the 5th one. Lane assist when trying to move away from a vehicle it pulls back almost getting you into an accident.

I was having oil consumptions issues which meant I had to put a quart of oil in my car every 500 miles I drove. Then I was driving when my check engine light started flashing and now my car can't drive without shaking a lot. I can't drive it anymore.

I believe that this car is a lemon. Ever since we bought it we have problems with the engine not performing right. I have got the engine system cleaned multiple times one at the dealership and one at Valvoline Oil Change facility. The engine still didn't run smooth. I would always get the oil changed on time and the vehicle has never been in a accident. Now just yesterday the vehicle while driving on the highway just stalled and wouldn't accelerate past 60mph. Now the check engine light is blinking and all of the lights on the dash are on. Also lately sometimes the forward collision lights will come on and other warning lights and sometimes they wont. Another light that intermittently comes on are the auto hold and epb light and this has been happening since we bought the vehicle. I have taken into Hyundai and they basically were...

Almost got killed!!! This car is dangerous!!! I feel lucky I can still write to you.

On March 13, 2023 while I was driving at about 70 mph on PA route 66, the engine suddenly stalled and fortunately, I was able to move to the emergence lane. I turned off the power and restarted the engine, and it worked. This is the third time that I have experienced the same issue, with other two on I-376. I also couldn't start the engine after refilling gas, so I had to wait for about 15 minutes. I took the car to a dealership but the diagnosis did not show any problem. There was not error code at all. On the internet, several possibilities were mentioned, but I do not have any idea about the root cause.

I have a Hyundai Tuscon 2019, which was pre-certified by Hyundai. This particular car was part of a lawsuit because of a knock sensor issue. The lawsuit information is here: [XXX] The knock sensor failing is not really what causes the safety issue. The engine symptoms when the sensor fails is the issue. The engine goes into "safety mode" which limits the car to a significant slower speed. The problem is that Hyundai has now tried to fix this issue twice on my vehicle, and the knock sensor continues to fail. To be clear, they've replaced the sensor twice. Based on the lawsuit, the court mandated them to fix the knock sensor. They have done that free of charge, but the sensor continues to fail. To me this sounds like a manufacture issue. It is incredibly dangerous when you're on a highway and the sensor fails. It happened to me,...

While driving, the engine completely lost power and was unable to go more than a couple MPH. We had it towed to the dealer and they told us it was a common issue on Hyundai engines and the fix was to replace the entire engine. It is available for inspection. Safety was compromised because we were in traffic when the power failed. Yes, we had the dealer confirm it. The only prior warning was that oil consumption was very high, which the dealer also confirmed is common.

The 2019 Hyundai Tucson was being driven home when all of a sudden acceleration was reduced to 25-30 mph. The Engine light went on while this happened. Got the car home, thankfully was off the highway and had it towed to the Dealership. Dealership informed me that it was an engine problem- a cylinder was blown and new engine would be needed on a car that had just reached the 40,000 mile mark. 40 other cars were brought into the dealership the same week and all needed new engines. If this car stopped working on the highway the consequences would have been dire! It is almost 2 weeks without a car- Dealership had no loaners left and we still don't have an answer from Hyundai if they plan to cover the engine still under warranty. We were told Hyundai had been denying allot of engines under warranty. And we were...

On [XXX] as I was driving down the highway, the check engine light came on the dashboard and the car lost acceleration. I could not go any faster than approximately 30 miles per hour. Very dangerous situation when you’re traveling in a lane of traffic that’s is doing 65/70 mph. I was able to get the car to Premier Hyundai, a dealer in Seaside, CA. At that time there was a recall for the Knock sensor. They replaced the knock sensor at that time and did some other services including an oil change and sent me on my way. They told me at the time that the code that had come up was P1326. Entering this incident now, because I realized I had missed reporting this specific incident. This VIN# has had the issues 5 times since the [XXX] incident and I feel very strongly that this is a HUGE...

On March [XXX], at [XXX]., on my way to a meeting, my Hyundai Tucson 2019 suddenly lost acceleration at 35mph. Immediately, the engine light came on and flashed very constantly. The acceleration pedal was not able to give more speed. There was a lot of traffic, and it was a very scary moment. I was very close to the Hyundai dealership at 750 N York St, Elmhurst, IL 60126. I spoke with one of their representatives, and I was informed that they would evaluate the problem, but it would be up to two days before they could give a full diagnostic; this step will be $185.00, but they will call me before they do anything with the car. The dealership paid for my Uber ride back to work, as they said that no loaner cars were available. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

bought the car in august with 82000 miles and within 2 weeks engine light came on and has had a knocking issue, carmax could not get me in for 4 weeks from the date i called for a "diagnostic testing". after replacing knock sensor -- engine stopped on 3/3/24 and now needs to be fully replaced

Was driving home from shopping on highway- lights flashed on dash and check engine light came on. Driving on highway and car goes into “limp mode” and will not go over 30 mph. Almost got rear ended by car coming up from behind traveling at normal highway speed. DANGEROUS!!! This is 5th time this has happened! The manufacturer needs to address these issues. Its happening to way too many people! [XXX] Theres a facebook group too but i can’t seem to get the url. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Engine failure I was driving down 422 East to king of Prussia. Engine failure I was driving down [XXX] to king of Prussia. My car jumped then began creating a sharp chirping sound from under the dash. I was in the middle of traffic. My safety was put at risk as there was no warning. I was able to get off the exit but immediately after, the cars engine light began to flash, oil censor, and I turned my car off. I was stranded on the [XXX] with cars zooming past me. I created a danger to myself and others as it was difficult to see around me coming off the exit. The vehicle is currently at Faulkner Hyundai awaiting a submission to the warranty company with me on my hands and knees praying to god it gets approved.

On [XXX] I dropped off the car to dealership because engine light was on. They said it was the Catalytic converter and replaced it with about 95,607 miles on it. On [XXX] I was driving on a 50mph road and my speed dropped to about 10mph and then the car began shaking and engine light came on. I got it back up 20 mph to get it pulled over to safety Avoiding an accident. I had it towed back to same dealership and told it was the Knock Sensor and had it replaced. On [XXX] engine light began flashing again and I had it towed back to dealership. Argued back and forth with dealership and corporate on safety and honesty. I picked it up on [XXX] and pulled out of dealership and it began jerking and shaking and lost power on a 45 Mph road stopping traffic and avoiding several...

engine light on and gave code p3001 so change spark plugs and ignition coil and still same code ,manufacturer run compressor test and they said compartment 1 there is no compressor.and suggested me to change engine and its not even 100000 mile on ccr it just 80000.

The vehicle was repaired under the major engine failure recall. Took the dealer months to replace the engine and now they are reporting the transmission is bad too. The car had absolutely no issues pre engine failure leaving me stranded. From reading up on forums I think transmission failures are just as common as engine leaving you stranded on a busy highway.

The contact owns a 2019 Hyundai Tucson. The contact stated that while driving approximately 55 MPH, the check warning engine light started flashing and the vehicle started to lose motive power and stalled. Upon inspection, it was discovered that the engine oil level was very low. The vehicle was towed to the local dealer, but the cause of the failure was not yet determined. The contact stated that an oil consumption test was being performed by the dealer. The manufacturer was notified of the failure. The failure mileage was 38,000.

On November 8, 2023 my check engine began flashing and my car lost Speed/Full power. I knew there was a knock sensor issue because I had this replaced in May of 2023 in order to comply with extended warranty services. I immediately pulled over to see if there was an identifiable issue. I was able to make it to a local orileys and they did a diagnostic check. It gave the p1326 code which I researched and found this to be the dreaded "needs a new engine code". I wasn't able to get an appointment until November 21st with a dealership. The one in my area wasn't taking anymore due to have over 100 vehicles with the same issue. My car has been at a dealership now since my November 21 st. It's extremely difficult to get a call from these people with any information. I called Hyundai and got...

On [XXX], my wife and I were traveling westbound on [XXX] in the left hand lane approximately 30 miles from Lincoln, NE. I noticed blue smoke coming from my exhaust. I had to maneuver to avoid traffic in the right hand lane to exit. The engine and oil light came on about 30 yards from where we were able to stop safely. There was a large amount of oil on the ground under the vehicle. The vehicle was towed to the nearest dealership in Lincoln, NE. On [XXX], the service manager called and asked who last changed my oil. He explained that the oil plug "was left loose, upon diagnosis for the oil light being on, removing the underbody shield to drain the oil out to inspect it, the plug fell out as it was laying on the shield." Prior to the vehicle becoming disabled there was not any indication...
