2016 HYUNDAI TUCSON Electrical System Problems

My 2016 Hyundai Tucson experienced engine failure consistent with known Hyundai engine defects. After reporting multiple battery outages, rapid oil consumption, and limited acceleration ability, outstanding warranties were checked and updated. However, the issues persisted, and the engine failed suddenly while I was driving. Hyundai denied warranty coverage without proof of the issues being unrelated to the warranty. This presents a serious safety hazard due to unexpected engine failure.

car often does not accelerate when hitting the gas. Was turning onto highway from a stop car did not accelerate causing other vehicle to swerve to avoid hitting me as my car would not move. Couple seconds later it moved

As I was driving I was stopped & told my car was on fire. I immediately stopped & hopped out & less than 30 seconds later half of the hood caught heat/fire & flew into the windshield breaking it. At least half The car is burnt to ashes

While driving, on multiple occasions all warning lights will come on and the car will start to lose power. The headlights constantly go off and come back on randomly. Turn the blinker on and the rear window wipers intermittently come on. The vehicle has been towed to the dealership so many times and we either get “can’t duplicate” or needs oil change, which had just been done. Now we are being told that we need a second engine replacement. Unfortunately this time it will not be covered by warranty. We have reached out to Hyundaii Motors 3 times and the BBB Auto but they stand behind it not qualifying for the Lemon Law. Hyundai should have some obligation as all these issues are “known issues” just not recalls.The 2016 Hyundai Tucson is not a safe vehicle.

Front passenger door will not open using the key fob. It has to be opened from the inside door handle. If there was an accident the door would not be able to open from the outside. This is a serious safety issue. There have been numerous issues with this problem. Hyundai should recall these vehicles for this safety issue

For about a year I have had issues with my car not accelerating in stop and go traffic. I push the gas pedal and it moves a little then will not go for about 20 seconds. Sometimes the engine will flutter. I have taken it to Hyundai and was told no diagnostic codes show and they can't find anything wrong despite bringing the reports from my auto shop of these things occuring. My car is going in yet again this week because this issue continues to get worse and I have almost caused several accidents in traffic due to not being able to drive. There is a recall however Hyundai says my car is not in the recall despite the same issues the recall is for. I have all routine service done when needed and have taken care of this vehicle but I feel like Hyundai should step up because...

My catalytic converter caught on fire a couple months back then I hit a code for the knock sensor replaced it and it started to act up again I can’t go over 49 burning oil took it to Hyundai now they are saying my engine is going out and I’m still panting carmart got the car

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.

While driving I noticed my ABS, Traction Control, AEB, and a couple of other lights came on. Upon restarting my car it was still there but the lights went away on their own after a few minutes of driving. They have been periodically turning and and off as I've driven the past couple of days. I went to the local mechanic shop who performed a diagnostic and found it to be a faulty left rear wheel speed sensor. When researching online, I've come across many people with the same make, model, and year as my car that have experienced this 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.

The front passenger window regulator failed in Jan 2025. Before the complete fail, the power window was becoming sluggish when lowered/raised. I just paid $1,000 to have the dealer repair. I have seen dozens of online items regarding the identical issue. I consider it a safety issue because of easy entry to the vehicle interior and contents, including inclement weather that can damage interior electrical components

The front passenger and rear window regulators failed within 1 month of each other without any warning or symptoms. After inspection, it was identified that the plastic window regulator was completely shattered within the door. There was no damage to my vehicle that could have caused this. With the window regulator not working, my windows were not able to be opened or closed. The front window regulator actually got stuck in a down position. After some additional research online, I found several others who have had the same issues with the window regulators on their 2016 Hyundai Tucsons. This is a safety hazard because if I were ever be in an accident or a place where I need to exit through my windows and they are unable to go up and down for a safe exit. I have spent over $1600 in repairs to fix an issue that is clearly...

Rear passenger door won’t open from inside or outside. Safety concern

There is a lot of oil consumption, and the turbo is shot. It sits in the back of the engine, which is not collecting air.

I’m the original owner of a 2016 Hyundai Tucson with 72,000 miles. I’ve recently encountered an issue where the front passenger side window is stuck down and won’t move. I’ve had it diagnosed at the dealership and found that this seems to be a common issue with this model year, related to the window regulator. I understand my vehicle is slightly out of the 5-year/60,000-mile warranty, however; this issue has made my car vulnerable to weather damage and theft, and it’s affecting my ability to use it safely. I’ve always maintained my vehicle according to Hyundai’s recommendations, and I believe this failure is premature for a part like this.

Three weeks ago my dash board lit up like an orange Christmas Tree, with "ABS failure" warnings. I found the Hyundai recall notice in our car file. It said that when the dash warnings appeared, the danger of an engine fire was imminent and that should contact the Dealer that I bought the car from (Hyundai Motors- Naples, Florida-USA). I did so. personally. An appt. was scheduled. This morning (Fri. 11/15/24)upon arrival, a pleasant young woman informed me that Hyundai sent out lots of notices like this, but they didn't apply to my vehicle. I showed her the recall notice with my car's Vin number printed on it. She went back to her boss who told her "We fixed that for him three years ago," Now, I am not certain of anything, but I NEVER brought the car in for an ABS system fix three years ago. I didn't know...

Front passenger door won’t open Defroster/heat won’t work on drivers side

Purchased a 2016 Hyundai Tucson with approx. 79,000. Was driving with all windows down one day. From the driver side window switch panel, I attempted to roll up the rear, left window.. The window would not roll up. The window rolls down when using the driver’s window switches for the left, rear window, but will not roll up. The rear left window switch will operate the window up and down only. Discovered this problem when going through a drive through car wash and the window would not roll up. Needless to say, the interior of my car got a good cleaning that day.

3 of my window motors do not work and my windows now will not roll up or down.

Passenger window regulator went out, then my window and my back passenger window went out and now I have 2 windows that cannot stay up and have paper holding them up.

All four window regulators have failed. The plastic gear has totally disintegrated and has had to be replaced. I have noticed that this has been reported by customers numerous times. I hope that we may be reimbursed for the failure of the part since it is very, very common among these models. I have retained all receipts for parts and labor.

Driver window won’t go up & front passenger window won’t go down.

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.

I own a 2016 Hyundai Tucson and have noticed that NONE of the doors other than the driver door will open either from the inside or outside. I have small children that I drive to and from school, activities. If we were to get into a wreck or were to run off rode into a body of water my children could drown or die due to doors not opening. This seems to be a very common issue with Hyundai and needs to be addressed and recalled and fixed by dealership immediately!

Three of the four windows will not roll up and down.

Ever since I bought my vehicle off the lot, my oil has been burning and/or leaking from the engine. I have been having to put oil in every 2-3 weeks. Also as a result of the oil problem, the oil gets on the spark plugs and coils and erodes them causing them to burn out every 6 months. The first instance I had with this problem was on a road trip to Texas from Tennessee alone. All four spark plugs began faltering on the highway where the speed limit was 75mph, easily a dangerous situation for a malfunctioning engine. I had to pay to repair my vehicle the next day and it totaled to a little under $600. I have been checking for recalls on my specific vehicle for months but have seen none, despite there being similar recalls on other Hyundai vehicles. The electrical problem I’ve been experiencing is...

My rear passenger door will not open from the inside or outside. My front passenger door has difficulties opening, I have to try to handle a few times. The front passenger door has been since I purchased the vehicle in 2022 but the rear passenger vehicle just started 5/2/24. The alternator has already been replaced as of 2022 and the front passenger motor has already been replaced as of April 2024 because the window stopped going up. And all of these have been at my expense!! I have read owner blogs that have all of these same issues. This is a HUGE SAFETY CONCERN. What if there is an emergency and I can't get my child safely out of his car seat? These issues, especially the door actuators, needs to be a recall and fixed immediately at no expense to the owners.

I have a 2016 Hyundai Tucson. So far I had to have both the front driver side and passenger side window regulators replaced. I just recently noticed that both of my back windows do not work. I currently have an appointment with the Hyundai dealer to replace both of the back window regulators. I drive around with a piece of duck tape holding the back windows up. Hyundai has to know that this is a problem. Hyundai requires an anti theft recall but it’s useless as anyone can pull my windows down by force due to broken regulator in each door. Insanely ridiculous and unsafe.

I was driving home from work and heard knocking sound come from engine. No sensors came on to alert me of any problem. I pulled over and checked oil. There was no oil and it was not due for oil change for another 1,000 miles. Oil is always changed between 3-5K miles. Took it to Gettel Hyundai dealership where it was purchased. They are unable to explain what or why this happened. Took claim out with Hyundai as there is only 60K miles. Hyundai and dealership offered no help because warranty had ended. Just told me it needed a new engine for $8K. Hyundai corporate denied claim also citing lack of service. That is not a valid reason and makes no sense. We provided every paper receipt showing diligent oil changes and required mile maintenance. They never bothered to do an engine oil burning test. After researching this online there...

Window regulator is not working in all the Windows I spend more 1000 dolars just to fixed the front ones still waiting to have money to fix the back ones the parts are made from cheap material this should be a recall

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.

When both driving and idling, the car will either stall or feel like it is about to stall, when all of a sudden the vehicle “pauses” for a second and then all of the dashboard lights come on. This has now happened at least 4 times in the past month. It will reset after turning the car off, but on more than one occasion after turning the car off, the engine doesn’t restart right away. Thankfully, the car has restarted and it resets the dashboard lights. My safety is a concern if my car stalls while driving at any speed! I have yet to take it to the dealer, as there’s a VERY long wait for an appointment - another recurring issue. No one has inspected this for me, and it is very concerning. There is plenty of evidence that this is happening to others in both online forums and...

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...

Front passenger door and rear passenger door will not open from the inside or outside. This is a major safety issue if someone has to get out in an emergency. I searched online and there are a ton of issues with the 2016 Hyundai Tucson in regards to the locking mechanisms in the doors.

None of my windows will go down. Vehicle has less than 25,000 miles.

Body: my vehicle has experienced a malfunction in the front passenger side door. This door does not open from the outside, regardless of it being unlocked. The failure occurs 99% of attempts to open said door. A repair was made by the dealer I purchased it from, yet the issue returned within a month. First incident: February 2022. Electrical: My vehicle has also experienced malfunctions in all four windows. The initial malfunction occurred in July 2023, when the front driver side window would not go down. Within a week of having the window regulator and motor replaced professionally, the window regulator failed again (would not go back up after being let down)-- with an additional failure in the front passenger side window regulator. The part was replaced for the second time by a different independent service provider. This time, the failure occurred when I inspected the service providers work. The...

My car has an engine oil leak that has been happening for over a year now since I bought it. I have to change my oil every 2,000 miles because of the leak, when Ive been told this car should be changing its oil for every 7,000 miles. My passenger door no longer opens from the outside once my car is unlocked. I have to put my window down in order to get inside and this is a safety hazard.

The windows of the 2016 Hyundai Tuscan go down and then the regulator went bad at that exact moment causing the windows to not go up, while driving on the highway. It is available for inspection. On a highway, I was going the speed limit between 65-70 MPH when I put one window down and attempted to put the window back up but I couldn’t. The pressure gets unbalanced and therefore impacts the drivers ears and passengers. I couldn’t even drive without the need to grab my ears because of the pressure. I had to pull over because the window wouldn’t go back up and the other windows wouldn’t go up after trying to balance the pressure in the car. I had to think quick and get on the side of the highway to figure out what happened. My ears wouldn’t stop popping and I couldn’t get back on the...

Recently the transmission was replaced because the original one was defective. After a couple of weeks, I had turned on the clean air control and it started blowing cold air, so I turned the heater control higher, and the air was even colder. I don't know why this started happening all of a sudden. I'm the type of driver that rarely turns on the heater or air conditioning, I always use the recycle air button that pulls from off the engine and from outside.

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...

The front passenger window failed to work. A week later drivers window failed to work. A week after repairing the two front windows the rear passenger side window failed to work. The failure of windows working is breaking of plastic regulators by faulty manufacturing parts. There should be a recall on these regulations. This is a safety issue!

The back left driver side door locked and can't be opened by any means. Child lock not on.

The right driver side door does not open from the outside after the car has been locked then unlocked using the key fob. Removing the key manually from the fob does not get the door to open. The only way to open the door from the outside is to leave the vehicle unlocked or to open it from the inside after going through another door.

Both of my back doors will not open from the inside or out. Thanks to youtube I watched videos on how to open doors from the inside I had to pull latch and then stick screwdriver in there to lift cable up up door would open. This is very dangerous for doors to not open up, taking time to use a screwdriver to open them up is ridiculous, according to youtube the cable was made too short. I called the manufacturer and they gave me a price of 700-1200.00 to fix. I really think this should be a recall. If someone in back needs to get out in emergency situation then they are stuck.

Complete Engine failure under 100k miles. Electrical issues with toggle switches

Window and motor regulators both went out in 1-2 weeks apart may 2023

Passenger doors do not physically open when unlocked from outside and inside. Known stretched cable problems, with hundreds of complaints when doing a Google search. Elderly parents cannot yank hard enough to get them open by brute force. God forbid if there was an accident, you would not be able to open to door from inside to get out and others from outside would not be able to open either to assist. Rolling death trap. Hyundai Korea knows about the door cable problem and fixes it for free. USA wants you to pay $400 per door to fix. Shame on you Hyundai USA!!!

While running errands in her 2016 Hyundai Tucson my wife rolled down her front driver and passenger side windows. When she encountered rain she attempted to roll both windows up, but the passenger side window would not roll up, causing a dangerous distraction where heavy rain was entering the vehicle while she was driving. Our mechanic inspected this part and said that the gears controlling the window were made of plastic which had been shredded over time and that the motor itself showed signs of corrosion. The vehicle is only 7 years old and has been well maintained, so i can't understand why this part failed so easily. Our mechanic informed us that this is a VERY common issue with Hyundai vehicles and that parts would be hard to come by because of high demand. This issue is available for inspection upon request and has been inspected by a licensed...

I've reported last year that I have an oil consumption problem.The car is not leaking to the ground.It's leaking within the car.I have replaced 2 catalyc converters in the past 2 years! The dealership ignores my requests and seems real shady.They rather I pay every year.I already feel it not working correctly,Its only been since October 2022,since i replaced the converter.I have contacted the corporation at Hyundai and nothing.They were a waste of time.I contacted the BAR and they were not much help either.I am spending constantly on this car with the same issue.What a lemon.Hyundai Corporation has to be held accountable for the mistakes.Thank you.
