What 1,536 owners told NHTSA about the 2016 Hyundai Tucson Fuel Cell

Have had to replace all four window regulators. From searching online, it appears there are quite a few other people who have had the same issue. Raising this issue in case others have to to create a recall. Thank you

Oil consumption is uneven, unpredictable, and has been a problem for at least 30,000 miles and since 2020. The car has ~74k miles on it and I carry a case of oil in the trunk. A couple years ago our catalytic converter clogged (I suspect from burning oil) and we were stuck on the roadside. Dealer replaced the catalytic converter under the power train warranty, but has not addressed the oil beyond a few consumption tests. They say it's "within normal parameters" but last night at a rest stop I had to add oil AGAIN. I feel like they're trying to wait until the warranty is up and then tell me it's not their problem.

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 put me and other drivers in danger. I am requesting: - Investigate why my VIN was excluded from Recall 16V-628. - Force Hyundai to reimburse repairs and extend recall coverage. - Require Hyundai to issue clear safety warnings after faulty repairs. Attached is the following: - The radiator repair invoice. - Proof of text from Hyundai. - Proof of my Vin being excluded from recall. - Quote for my transmission repair.

I have been dealing with ongoing engine performance problems for over a year. My Tucson consumes oil at an abnormal rate, and I constantly have to refill it. There is also sluggish acceleration, and the Check Engine Light has stayed on despite multiple inspections and maintenance efforts. I’ve seen hundreds of complaints about this exact issue from other Hyundai owners. I also found that an NHTSA investigation is ongoing, yet Hyundai continues to deny responsibility, often blaming the issue on the owner. I believe this is a safety concern and a manufacturer defect that needs to be addressed before more drivers experience full engine failure. Please investigate this further and include my VIN in any future action or recall.

The reason of this complain is due to excessive oil consumption which now damaged my catalytic converter against Hyundai Motors America. The complained started 2021 where we noticed that the low oil engine light up after only 1500 miles from last oil change. We submitted the complained with dealer (Carlsbad and Escondido CA) and my car failed 3 consecutive oil consumption test and Hyundai performed an engine cleaning, claiming it was going to fix the problem. This happened when the vehicle was still under warranty. At the time they said that if this did not fix the problem, they were still going to fix the car since the issue happened under warranty. The engine cleaning DID NOT fixed the problem, my car no longer has warranty and my catalytic converter fails and makes the vehicle inoperable in highway (engine ceases to accelerate) . We submitted a complain with Hyundai corporate and they denied fixing our car since the vehicle was no longer under warranty. I would like to ask for them to fix the engine and catalytic converter make the car operable again.

Door latch - after a few attempts of trying to open my rear passenger door. The handle does not seem to function properly and I’ve seen that a lot of 2016s Tuscon have this issue with their doors

Brakes locks and the vehicle do not move. Vehicle was parked. Recently I noticed that the vehicle was breaking by itself instead of keep moving. Until today the vehicle brakes lock and do not move.

-Power window failures of all 4 windows. -Windows will not open and close which creates a safety issue in case of an accident that renders the doors inoperable and escape is needed via windows. Also, if the driver is pulled over, the car windows do not work which makes the driver have to open the door which puts both the driver and police officer at risk. -Both a dealer service center and an independent service center has confirmed the problem. -Component was inspected by both a dealer maintenance shop and an independent repair shop. -There were no warnings.

Me and my daughter were headed back home from a family trip and we were stranded on the side of the road luckily we had family tailing us!! My engine light came on while we were still in the city in Savannah so we stopped by an autozone and changed the spark plugs so the engine light stopped blinking but when we got about 20 miles from home it stopped going we had to pull over it started smoking and it was really hot but the temperature had never moved we had it towed home!! I keep my maintenance up regularly on my car I had 2 mechanics check it out they both said the piston is breaking the spark plugs and it’s something down in the motor that’s doing it I should not have any motor issues at all with my car!! Especially when I do my part at keeping it up I was quoted 7,738 to fix my car which I don’t have both mechanics said the engine in those cars are no good and it’s been recalls on them just not my model it’s not right I’m out of a car and no way to work or no way for my kids to get around they have to ride in Lyfts and Ubers with strangers I feel like my car should be fixed because I did my part at keeping it up and I’m still out of car and frustrated due to the companies negligence!!

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.

total engine failure. per dealership mechanic, random misfires on all cylinders with a dead miss on 4

Engine has rod knock and low power due to rod bearing failure. There was never an illuminated oil light or message of any sort prior to failure. this vehicle has had oil changes regularly and never been an issue till now. With Hyundai not having a recall on this engine, and seeing many other reviews about this same issue it is a very dangerous issue leaving people stranded and loosing power in times where serious harm issues could occur and this issue is very costly being that the engine will have to be replaced. As a consumer taking care of the vehicle and still the engine failing due to the lack of integrity of Hyundai I believe Hyundai should step up and make it right and take care of the people who have spent there hard earned money on these cars and are now left in the dark.

The contact owns a 2016 Hyundai Tucson. The contact stated that while driving on the highway at 55 MPH, the vehicle lost automotive power and started vibrating abnormally. There were no warning lights illuminated. The contact pulled over and was able to restart the vehicle. The vehicle was taken to a local dealer where the vehicle was diagnosed and the contact was advised that the ignition coils, water pump, spark plugs, valve, oil filter, and the engine were faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 113,000.

Was driving down busy road when engine suddenly knocked violently and shut off rendering car inoperable. Inspection revealed low oil, despite not being due for an oil change after and no visible/identifiable leaks. Investigation by mechanic resulted in being told that numerous Hyundai engines like this are having the same problems and need total engine replacements. The call only had 70,000. Dealership said they see one a week.

Acceleration issues especially after coming stop. When proceeding to accelerate you can push pedal multiple times before the car jerks into movement.

The vehicle does not accelerate entering roadway, transmission replaced in 2022, catalytic convertor replaced in 2024. Several instances occurred when entering highway vehicle lost power and failed to merge safely, ultimately requiring hasty exit to roadside to avoid collision. The vehicle was purchased used but has been a safety risk since purchase date. Originally diagnosed transmission, then catalytic convertor, then knock control sensor. Engine oil is replaced more often than routine maintenance and refilled in between oil changes. Autonation Hyundai Mall of Georgia originally assisted with transmission replacement Feb 2022, catalytic convertor was replaced in Mar 2024. The vehicle has been parked for considerable time while insurance and car payments continue. In Feb 2025 my daughter was driving and was nearly rear ended when vehicle failed to accelerate, it has primarily parked since that time while exploring repairs. Car fails [XXX] enroute to game. Last quote to repair catalytic convertor was Total Automotive in Gainesville Ga. around 19 May 2025. I believe this vehicle poses a significant safety risk due to acceleration delays, all attempts to resolve have been unsuccessful.

I received a email about a recall my vehicle has I made an appointment with the Hyundai dealership which sent the email. Hyundai Wesley Chapel in Tampa FL and I took it in on 6/16/2025 at 10am and waited an hour. The service advisor came to me and advised me that my vehicle was purchased in Puerto Rico and cannot be serviced because they don’t have the parts. This is unacceptable and don’t understand why they went through the trouble of sending me an email regarding this recall to waste my day at the dealership.

Was driving down busy city road when engine suddenly knocked violently and shut off rendering car inoperable as traffic had to go around my disabled vehicle. Inspection revealed low oil, despite filling 4 weeks prior after change and no visible/identifiable leaks. Investigation by mechanic resulted in being told that numerous Hyundai engines like this are having the same problems and need total engine replacements. They said that they "see this at least once a week in these Hyundai's and Kia's". There were no warning lights or anything prior to the event.

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.
