2016 HYUNDAI TUCSON Power Train Problems

The contact owns a 2016 Hyundai Tucson. The contact stated that the check engine warning light was illuminated, and there was a ticking sound coming from the front of the vehicle. The vehicle was taken to Auto Zone, where a mechanic diagnosed the vehicle with a knock sensor failure. The knock sensor was replaced. The mechanic informed the contact that the vehicle was included in Manufacturer Campaign: CS966 for the transmission control module (TCM). The vehicle was taken to the dealer, who confirmed that the vehicle was included and the software update was performed. After the vehicle was repaired, the check engine warning light was no longer illuminated; however, approximately 30 minutes later, the vehicle failed to exceed 35 MPH, and the check engine warning light started flashing. The vehicle was returned to the dealer, and the contact was informed that the software update caused the vehicle to enter LIMP...

Car died/lost power while driving in traffic 11/28/25. Good Samaritan was kind enough to push me off the road out of traffic. Car was towed to Hyundai dealer that day, then 12/1 told engine failure, required engine replacement. Class action lawsuit settlement for engine replacement, but denied by Hyundai because of "neglect", since I am not able to locate all of the service records that they request. Known faulty rotating assembly, and Hyundai has implemented concerted practice of denying warranty coverage for failed engine. Now having to pay almost $8K to replace with new engine, but concern that new engine will have same issue. (multiple posts about this). There was high potential for significant traffic collision, injury due to sudden, catastrophic engine failure. Traumatic experience.

While driving on the highway at normal speed, the vehicle suddenly lost power and shut off without warning. There were no warning lights or messages prior to the loss of power. I was able to safely pull over, but the engine would not restart at that time and the vehicle required towing. The sudden engine shutdown occurred in active traffic and created a safety risk due to loss of propulsion. The vehicle later restarted, but I brought it to an authorized Hyundai dealership for inspection. The dealership diagnosed internal engine damage, including piston ring failure and cylinder wall scoring, and advised that the engine would need to be replaced. Since the incident, the vehicle has shown intermittent oil pressure warning lights and reduced performance. The issue has been confirmed by a dealer inspection. The vehicle is currently not considered reliable or safe for regular driving.

My Tucson has been using an absurd amount of oil for the past 30,000 plus miles i had it in the shop for repairs for the exhaust/ turbo leaking due to broken stud bolt that finally was covered under warranty. But did nothing for the burning of oil. No oil leaks. It used a quart for every 500 miles. Now no warranty left i have a cylinder #1 misfire and have replaced sparkplug and will not come out of limp mode. Within a mile of driving the plug is oil fouled and goes back into limp mode. Probably will get no help from Hyundai to rebuild/ replacement of the motor.

Engine or transmission The vehicle has stalled randomly multiple times on the freeway, business roads and intersections, not accelerating and burning through oil Dealership says they cannot figure out or replicate the issue No check engine light or warning of any kind given

The car will fail to accelerate when turning at a stop and starting at times. It’s very dangerous b/c you can be at a complete stop on the highway and try to start going and the car will sputter out. There is no doubt that something is wrong with the transmission and has been for a year but didn’t register until 12,000 miles later.the car only has 70,000 miles in it. I kept taking it to Hyundai to be looked at and they kept telling me it was just how the dual clutch transmission works. Now a year later they say it’s registering as a problem but don’t want to cover it under the warranty b/c I’m a second owner. If I was the original owner, it would be covered. If you look at the history of this year and make, you can see there have been issues with this...

1. "Transmission or ECU" 2. There is a lag and sometimes almost stall when accelerating from a stop. I was turning into a lane from a stop sign and the car decided to not move for 3-4 seconds after pressing accelerator. If people had come around the blind corner when that happened I would have been T boned. 3. All four people living in my house...... and our mechanic. Yes 4.No, because were not paying for something that has had a recall. 5. We inherited this car from my grandmother and she knows nothing about cars so she never thought anything was wrong. Since the day we got it, it has been doing the same thing "DCT CONTROL LOGIC UPDATE & P0128 DTC LOGIC UPDATE (RECALL 149)" #17-01-023

i bought the car used, i took it in for diagnostics on my transmission. they claimed i needed a new one, not claiming i need a new clutch. my car’s model and year match the DCT recall problems. but not the vin. when my car was in the heat or accelerating it had the same issues listed. i believe this is a manufacturing issue.

1. December 2024: Hyundai dealership diagnosed my transmission as defective (unable to shift properly) and recommended a full replacement. Despite this, they assured me the vehicle was "safe to drive" without disclosing risks. - Unedited dealer text: "The tech said he doesn’t think it will break down or leave you stranded, he just can’t get it to shift correctly." - No warnings were given about prolonged use, highway driving, or potential failure. 2. Post-Repair Damage: After relying on Hyundai’s advice, the transmission worsened, causing additional damage (e.g., radiator failure). 3. Recall Negligence: My VIN was wrongly excluded from Recall 16V-628 (transmission control issues), despite exhibiting identical symptoms. They didn't cover repairs, despite their technician confirming the defect. The safety impacts are as follows: - Sudden loss of power while driving (e.g., inability to accelerate or shift). - Increased crash risk due to erratic transmission behavior. - Hyundai’s failure to warn...

Misfire, excessive oil consumption, engine knocking, loss of power/acceleration, gas smell, excessive gas consumption

I’ve been having ongoing issues with my 2016 Hyundai Tucson where the car struggles to accelerate, especially after stopping at red lights or pulling out into traffic. Sometimes, when I press the gas pedal, the car either hesitates badly or doesn’t move at all. A few times it’s completely stalled while trying to make turns or cross intersections, which has been really scary and dangerous. I did some research and found there was a known recall for this exact problem related to the Transmission Control Module software and the dual-clutch transmission. The symptoms described in the recall match mine perfectly, but when I checked my VIN, my vehicle isn’t included. I haven’t taken it to the dealer yet because I’m worried I’ll have to pay out of pocket for something that I believe is part of a known manufacturer issue.

The contact owns a 2016 Hyundai Tucson. The contact stated that while driving at undisclosed speeds, the transmission started slipping while accelerating. There were no warning lights illuminated. The contact stated that the failure was related to NHTSA Campaign Number: 16V628000 (Power Train, Electrical System). The contact called an independent mechanic who provided a printout of a recall. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 108,000.

When accelerating, like taking off from a red light or through a turn, my car begins to shake like it’s unable to change gears correctly, and sometimes leads to the car stalling in the middle of the street and intersection putting my in danger of being hit from other drivers. It’s also happened that when I press the gas after being stopped at a light, my car RPM goes up but I don’t move and then the car jolts forward quickly. This has been happening for years and when I take it to Hyundai they tell me “that’s just how the car runs” which seems incredibly unsafe.

I bought my 2016 Tuscon brand new. Ever since I bought the vehicle, I've complained to the dealer about the transmission slipping. They have told me that this issue is common but there is nothing they can do. Now it seems to be getting worse so I decided to look up the problem and found out a recall notice was issued for some 2016 Tuscons but mine wasn't included. My Tuscon has the exact same problem as described in the recall issued by Hyundai. I"ve almost been in accidents because you press on the gas to go and it hesitates,l. What can I do? My Vin number is [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My backup, my reverse is not working after 30 minutes the car is running.

loss of power, transmission slipping. unable to get car to move creating hazard. happened 5 times. Diagnosed by dealer as systemic transmission component failure and known issue. many of the same complaints on internet, Code p1921

The contact owns a 2016 Hyundai Tucson. The contact stated while driving approximately 40 MPH, the vehicle lost motive power. The contact depressed the accelerator pedal and the vehicle lunged forward. The contact stated no warning light was illuminated. Additionally, the contact stated that when the vehicle was stopped, after depressing the accelerator pedal, the vehicle hesitated and then lunged forward. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The contact researched online and related the failure to NHTSA Campaign Number: 16V628000 (Power Train, Electrical System); however, the VIN was not included. The failure mileage was approximately 140,000.

The contact owns a 2016 Hyundai Tuscon. The contact stated that while driving at various speeds the vehicle would begin sputtering and the transmission would begin slipping. The transmission would also slip when attempting to accelerate after being parked or idle. There were no warning lights. While driving approximately 45 MPH the vehicle suddenly began going in reverse. The contact immediately placed the vehicle in park to turn off the vehicle. After restarting the vehicle the contact attempted to drive it but failed to accelerate. The vehicle was only able to be driven in reverse. The contact reversed into the nearest parking lot. The vehicle was towed to a certified mechanic where it was diagnosed that the transmission failed. The transmission needed to be replaced. The vehicle had not been repaired. The manufacturer was not made aware of the failure. The failure mileage was 90,000.

Vehicle started to shake and lost acceleration. Gave engine Code P073F Unable to engage gear 1. Hyundai shows Recall Campaign for this issue but dealer refuses to acknowledge it, and says it needs new transmission. They state transmission damaged clutch rather than clutch damaged transmission.

The vehicle intermittently fails to accelerate without warning or notification. The throttle pedal goes to the floor without the engine stalling or rev'ing but also fails to propel the vehicle. This has occurred when crossing lanes of on-coming traffic placing the operator in an EXTREMELY DANGEROUS situation. In addition, the vehicle also intermittently fails to go in reverse. These issues are most prevailant in warmer summer temperatures. Neither of these issues directly triggered a MIL light. MIL lights did occur independent from the cited issues but would typically self clear. On one occasion I was able to get a scan of the vehicle with an active MIL that yielded a P1921 Gear 2 System Motor Thermal Damage. Shortly after the scan, the code cleared and MIL went off. The conditions were NOT able to be reproduced by the dealership. They were also not able to clearly diagnose what would cause...

Oil consumption is excessive it has caused the engine to have a knocking noise even though routine oil changes have been up to date. Yes available for inspection. This may cause the engine to seize at any given point while in motion. No, I have not been able to take the vehicle to a dealership yet. No, vehicle has not been inspected. No, no check engine/warning light has turned on. Knocking noise began June 28th 2024.

Vehicle transmission prolongs shifting from 1st to 2nd gear, and from 2nd to 3rd gear. Vehicle only has 55000 miles on it and we are second owners of the vehicle. This has been on ongoing issue with the vehicle that we attributed to design but a month ago, the check engine light came on. We took is the Ray Skillman Hyundai who diagnosed that the transmission was the cause of the check engine light and that the entire transmission will need to be replaced at a cost of a little over $7000 to us. The original warranty on the car offered a 10-year, 100,000 mile warranty but Ray Skillman Hyundai nor Hyundai Corporate will replace the transmission without charge. We also know of many other issues related to transmission components of other Hyundai vehicles. The vehicle puts at risk because the unexpected pause puts the drivers behind us at risk...

The contact owns a 2016 Hyundai Tucson. The contact stated that after the vehicle came to a complete stop, the accelerator pedal was depressed, and the vehicle lurched forward but hesitated to accelerate immediately. An unknown warning light illuminated, and the check engine warning light was later illuminated. The vehicle was taken to an independent mechanic, who retrieved DTC Code: P073F (Unable to Engage Gear 1), but no repair was recommended. The vehicle was not repaired. The manufacturer was not made aware of the failure. The contact related the failure to NHTSA Campaign Number: 16V628000 (Power Train, Electrical System) however, the VIN was not included in the recall. The failure mileage was approximately 93,000.

My 2016 Tucson Sport with Eco Shift has a dangerous problem with the transmission. Intermittently It will not move when I give it gas. The RPMS go up to 6000 but the car wont move. Its the DCT transmission. Today I took it in for the 3rd time and I don't want it back until its fixed. This is a very unsafe vehicle to drive since you would not know when it would just stop shifting and driving. Have registered a complaint with Hyundai Motors as the service department does not know when the vehicle will be repaired. 

The engine sign keep blinking on the dashboard, I went to auto zone, they scan it and say that the power train system with code P1326 Glow relay short circuit is the problem. This would be the second time it comes on. The first time it came on but then stopped in a few days but it’s on back again.

Car shuddering going from full stop to 1st gear, not fixed by software update. Clutch replaced under drive train warranty at no cost to me.

A/C failure & Heat Failure which resulted in an accident. Was not the thermostat. ACCEDENT was unable to defrost/defog windows, causing the driver to crash

The contact owns a 2016 Hyundai Tucson. The contact stated that while attempting to accelerate from a stop, while depressing the accelerator pedal, the vehicle failed to immediately accelerate as intended, before suddenly lurching forward. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to determine the cause of the failure. The dealer informed the contact that the vehicle was functioning as expected. The vehicle was taken to an independent mechanic, who was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 53,000.

The engine began to make a knocking noise. Upon our inspection, the vehicle had lost all oil. Vehicle was towed to our local dealership. Dealership informed us a bearing had become worn causing rapid oil loss and a rod to break, sending metal shards into the engine compartment. Engine could have seized up or caught on fire, had the vehicle continued to run. Dealership informed us of other Hyundai recalls for the same issue, however we were told our year/make/model was not included. Vehicle had been at same dealership 2 months prior for a heat/AC issue and a complete inspection was completed. No indication of bearing, oil, or engine issue was noted. No warning lights came on at any point.

Engine heating problems, electrical problems and now engine failure, the vehicle is no longer safe to drive. The vehicle is available for inspection. Other vehicles of same make, model, and year have been recalled for these issues however mine has not. I feel it has the same types of issues and safety concerns which should be recalled. The issues began with electrical problems inside the vehicle, random check engine lights coming on then off and other lights popping up in the dash board, the car was not accelerating properly, took the car in and they could not find a problem or fix it. The engine began heating and the speed of vehicle was also being affected. The car would randomly slow down quickly while on the highway at 70 MPH which happened a couple of times and was not safe at all, it could have caused a horrible accident. I...

Vehicle has 101k miles on it, just over the 100k Hyundai warranty. Vehicle began shaking and sputtering while driving, and check engine light illuminated, I was able to get it to a local mechanic. Mechanic said it had multiple codes (P300, P302, and P304). They did a compression test and said the engine has internal failure and should be replaced; quoted 13k to replace. I had it towed to the Hyundai dealership where I bought it, and they are investigating it. The service manager told me even with perfect maintenance records, Hyundai will likely deny a goodwill claim to replace the engine. Looking at all these engine failure complaints for this year model, it is clear this is an ongoing problem and Hyundai needs to issue a recall.

Failing Transmission including inability to engage reverse and slipping gears while shifting.

51k miles and engine went out on the highway. No lights or warnings until afterwards. We were able to safely pull over onto the shoulder and had the vehicle towed to the dealer for servicing.

I already had a recall scheduled 4 days before this accident but 2 days before the engine failure I heard a ticking in the engine , didn’t think much of it because the engine was still running ( 93k miles on the car) so I was going to tell the dealer the problem when I took it for the recall fix appointment but on the way home my car instantly went from 70-30 in the middle of the highway I had the car towed to the Hyundai Dealer and they said rod had broke and said also something about the oil being dirty when I literally had the oil changed days before , but end result my 2nd owners warranty didn’t cover the vehicle even with rod failures being a recurring problem with my trim. They told me a new engine would be 13,500k while still owing 10k on the...

I bought a used 2016 Hyundai Tucson locally. Had the car 3 days, & both rear window actuators had to be replaced. Had the car a week, oil pump/pan seal failed. Then the rear seal fail. Then the boot on the right CV joint failed. The aAC started blowing hot on the passenger side, while cold on the driver side, but I DON’T have dual controls for the temperature & it’s full. Bluetooth randomly connects/disconnects. Gas gauge is inaccurate says 40 miles left & then suddenly your light is on & it says you’ve 20. REPEATEDLY replaced my brake light bulbs/front turn signal bulbs, several times within a few months of each other, often on the same side. Having my phone plugged into the charging ports, the phone often overheats to the point of being too hot to touch. Even placed out of the sun’s rays, & shaded. Must pull...

I have been to multiple Hyundai dealerships, and opened about 3 to 4 Hyundai consumer cases; for WELL known engine problems. My vehicle has failed oil tests and combustion tests done by Hyundai dealers. Springfield Hyundai/ Genesis kept my vehicle for 5 months claiming they found issues with the engine that was consistent with the other vehicles recalled for obsessive oil consumption. After their findings, Hyundai corporate decided not to do any repairs, after 5 months! They claim my vehicle is out of warranty and can not carry through the goodwill repair/replacement. Hyundai corporate and I have proof of my engine complaints and failed oil tests before 100,000mi warranty expired (which is why Hyundai submitted a goodwill repair request on my behalf took the car in the first place). My vehicles VIN is not included in engine recall, nor the theft recall. My car has been driven away from the...

I recently purchased a 2016 Hyundai Tucson, Limited 1.6T. After a few weeks of driving I noticed it would shake when at a stoplight. It also loses acceleration and 'skips' when making turns, going over speed bumps or just taking off from a complete stop. There have also been times that I press the accelerator pedal and the car doesn't move. After researching I discovered this is a known issue and Hyundai issued a Technical Service Bulletin (number 21-AT-014H) in August 2021 instead of a recall. My vehicle had less than 40K miles on it when I purchased it (from a non-Hyundai used dealership) I took my car to a Hyundai service center, when I explained the problems to a technician, he suspected he knew exactly what the problem was. I chose to have them perform a "judder" test to confirm and the tech was right, it did in fact...

When coming from a stop and trying to accelerate the transmission slips and makes a strange noise. After a few seconds of releasing the gas pedal, it will drive again normally. It is intermittent and happens from either a full stop to first or first to second (while stuck in traffic). My vehicle should be included in the dual clutch transmission recall that is available for other vehicles.

The contact owns a 2016 Hyundai Tucson. The contact stated that the vehicle failed to reverse. After several attempts, the vehicle worked as designed. While approaching a stop, the vehicle was jerking. The check engine warning light was illuminated. The vehicle was taken to the local dealer, who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was approximately 94,000.

Excessive oil consumption NM, replaced catalytic converter twice. Losing power again. 122450 miles. Trans mission slipping, not shifting into higher gear. Gas mpg down to 19mpg. Unsafe on highway, loses speed and revs too high

Car shakes when when starting or stopping

The contact owns a 2016 Hyundai Tucson. The contact stated that all four automatic windows failed to operate as needed. The front driver’s side window started failing and an appointment was scheduled with the dealer to repair the window. While testing the windows in the dealer parking lot after the repair, the front passenger’s side window fractured, and the dealer agreed to cover the cost of the repair free of charge. Over time, the rear windows started to lower independently, and the vehicle was repaired by an independent mechanic. In addition, the contact stated that the vehicle intermittently failed to accelerate while depressing the accelerator pedal. There was no warning light illuminated. The contact stated that the vehicle lunge forward while accelerating. The manufacturer was also notified of the failure. The vehicle was not repaired. The failure mileage was approximately 20,000.

excessive oil consumption. it has been confirmed by valvoline instant oil change center. after an oil change, round 600 miles the oil is to be checked and topped off completely because the reservoir is bone dry. can not make it a complete 3,000 miles until the next oil change. the oil has to be topped off at least 2-3 times until the next oil change. there are no warning lamps, messages, or other symptoms to notify of the problem. it has been inspected by hyundai dealership, whom at someone point replaced the turbo in the limited 1.6L. also, the windshield wiper reservoir decided to stop working. I have to wait until it rains or go through a car wash to clean my windshield. all hoses have been checked and there are no leaks or disconnection of the hose. the windshield wiper fluid will not come out and remains completely full.

While driving the car, when you press down on the accelerator to pick up speed, the car actually slows down. Eventually it will run normally at speed, however it creates a significant risk when pulling into traffic.

The contact owns a 2016 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power. The contact turned off and restarted the vehicle and the check engine warning light illuminated. The vehicle was towed to the dealer, where it was diagnosed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The contact related the failure to NHTSA Campaign Number: 16V628000 (Power Train, Electrical System) however, the VIN was not included in the recall. The failure mileage was approximately 51,800.

The vehicle is burning oil quickly. I have always gotten the oil changed on time. I just reached 89,000 miles and the vehicle has begun shaking when I accelerate and the check engine light has been flashing. I checked the oil and it is at the half way line between Full and Low - even though I just had it changed 3 weeks and less than 1,000 miles ago. I took it to the dealership, they said they do not recognize a problem with oil consumption. I told them my check engine light was flashing and it felt like it was going to stall when accelerating. The dealership said they used to do diagnostic testing, but don't anymore. They said they would look into, but I would have to pay $135 for the diagnostic testing.

Unable to move the car while in traffic. The car slows down in traffic creating the possibility of accidents/crashes. The car will not go forward and only moves in reverse.

Upon acceleration onto highway or up a hill the car at times will rev and not shift or move /increase speed. Getting onto the highway I have had to pull into the shoulder until vehicle snaps out of it and decides to shift. Extremely dangerous & happening more often than not now.

I have a 2016 Hyundai Tuscon Limited Turbo which I bought USED in August of 2018. The same week I left the lot I returned multiple times complaining that the car was hesitating and seemed like the transmission was having problems. The car would hesitate to go from a stop, several times leaving me and my infant (at the time) in the middle of intersections crossing traffic and unable to move. It almost got us SLAMMED multiple times. I explained this to them and they just kept telling me it was because of the turbo. I said NO ONE in their right mind would manufacture a car that goes fast at the cost of safety. That was insane to me but they kept sending me home. I returned over and over and over again for the entire 1st year I had the car with no resolution. Eventually, I also discovered...

My vehicle is burning excessive amounts of oil and no leaks can be found. Almost one quart every 750 to 1,000 miles. The turbo went bad recently and had to be replaced at a cost of $1,400 which, I'm told, is possibly due to the oil consumption problem. All services have been done at Hyundai dealership every 3,000 - 5,000 miles. I travel the interstate every day and am worried about engine failure in rush-hour traffic. Dealership indicates the only thing they can do is replace engine at a cost of at least $12,000!!
