What 364 owners told NHTSA about the 2022 Hyundai Tucson Fuel Cell

It’s been three years now and I had “Brake system failure” happened two times in 3 years. When traveling the brake system warning appears and while driving, and stopped at sign brake releases slightly and car would start to move unless I apply brakes firmly again. When slowing down at traffic lights holding the brake doesn’t bring car to complete stop. I had apply brake, slightly release and then apply again until car comes to full stop. I was told they need to replace IEB module and brake pedal module replacement. I checked in Reddit and other platforms where users had seen the issue multiple times on their vehicles. Also had an issue with Fuel system like replacement of Egr valve which seems to be common on multiple Vehicles.

I took the vehicle to the service station because it takes a long time to stop, and I braked close to a vehicle on several occasions. They replaced the brake pads, and when I took the baby in, it was worse. When they finally agreed to let me take the baby in for another inspection, they said they would have to remove and reinstall the parts. Two months later, my baby started doing the same thing.

Both horns needed to be replaced three times due to both stopped working and I listed the dates below. First time replacement: 4-6-24, Second time replacement: 10-9-24, Third time replacement: 1-16-25. Now on 9-26-25 both horns stopped worknig again, I checked the horn fuse and that is good. I now need to call the dealer to have both horns replaced for the fourth time. I also contacted Hyundai's national customer service to log a complaint as well. To me this is a safty issue since the horn is used to possible prevent an accident. I check the horns when I drive the car since they go bad so often and I have under 28,000 miles on the vehicle.

The contact owns a 2022 Hyundai Tucson. The contact stated that there was a delay in the operation of the rearview camera to provide an image while reversing. The contact stated that the rearview camera remained activated temporarily while the vehicle was in drive(D). The contact stated that the infotainment system screen turned off and activated functions unintendedly while driving. The vehicle was taken to the dealer, where the infotainment system and the rearview camera were replaced twice; however, the failure persisted. Additionally, the contact stated that while attempting to shift from reverse(R), the gear shifter was sticking and failed to shift to drive(D). The contact was able to shift to drive(D) after several attempts. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 30,000.

The computer(s) responsible for many of the safety systems have faulty software. The computer vision system incorrectly assess condition of the roadway and issues warnings that obscure the instrument cluster. The computer vision system also incorrectly determines that a collision is imminent (despite no obstacles being present) and activates the braking system. Hyundai has been aware of this issue since 2022 and has previously released a software patch to correct it. However, unpatched vehicles are still being sold (and resold) by Hyundai dealerships without being fixed because Hyundai has chosen to rescind the availability of the update. Unpatched vehicles are on the road preventing drivers from properly monitoring vehicle operation as a result of the continuous warning obscuring the cluster and are jeopardizing the occupants and other road users when the vehicles spontaneously initiate panic stops for phantom obstacles. Hyundai refuses requests to provide the existing update files because a future update with an uncertain release date is planned; release of the "upcoming" update has seemingly already been delayed 8 months.

While driving, without warning, all malfunction lights came on the dashboard and stayed on, including check engine light. The speedometer and rpm show as zero even though I’m moving. The power steering locks up. Scary as hell! This has happened 5+ separate times within the past 2 months. The first time I had it towed to the dealer and they said it was caused by a Karr alarm that was pre-installed by the dealer prior to my new purchase which I never authorized and was never activated. They said it was causing a short even though it happened 2+ years after purchase. It was removed by the dealer for free and the electrical issue happened again the next day while driving. It was towed to the dealer again and after a week the car was returned to me with no diagnosis as they were unable to replicate. It happened 2-3 more times and I got it towed to the dealer for a third time as I don’t feel safe driving this car at all. I am scared the car will die while on the highway. Car still at dealer.

I went to fill up the gas and the gas cap door would not open. The gas station attendant tried to help with no luck. I drove to the dealer - the fuel release actuator had failed. Part was replaced under warranty. I am lucky I had enough gas to get to the dealer. Very scary when you can’t put gas in your car!

On August 14, 2025, at approximately 12:40 AM, my 2022 Hyundai Tucson Limited suddenly stalled while driving and became completely non-functional. The vehicle had about 25,000 miles at the time. This left me stranded on the highway in the middle of the night, creating a serious safety risk for myself and other motorists. The vehicle was towed to a Hyundai dealership. The dealer claimed the issue was caused by “carbon buildup” and stated that the problem would only be considered “repaired” if I paid for a fuel injection cleaning and fuel induction decarb service (about $500). These services are not listed in the Hyundai factory maintenance schedule, and no diagnostic evidence (photos, test results, or measurements) was provided to support the claim. Because the stall made the vehicle inoperable, I believe this should have been handled under warranty. Instead, I was pressured to pay for optional services in order to have the safety issue resolved. Safety Risk: The vehicle stalled without warning at highway speed, placing myself and others at risk of collision. Based on the dealerhip this needed to be serviced every 20k miles and hyundai deosnot recommend to consumers for some reason..

I have had 3 fuel injectors go out on my 2022 Hyundai Tucson. When this happened it was completely random and my car would stall and I would be stuck on the side of the road. I have had to miss work due to this happening. They told me that they are only able to replace the broken one each time instead of replace the all 4 while covered under warranty. They also told me that fuel injectors breaking is a common problem in 2022 and newer Tucson's as they are higher pressure systems than previous models. Im worried that this is going to keep happening and I'm going to keep breaking down due to fuel injectors breaking and end up stranded somewhere.

While driving my 2022 Hyundai Tucson at highway speed, the panoramic sunroof spontaneously shattered with a loud “explosion” sound. There was no road debris, overhead structure, or external cause, and no warning lights or prior symptoms. The glass shows a central hole with spiderweb cracking radiating outward, which is consistent with a manufacturing defect in tempered glass panels, not an impact. The sunroof shade was closed, preventing glass from entering the cabin, but this failure created a serious safety risk to occupants and nearby drivers. This matches numerous reports of Hyundai panoramic sunroof failures and is similar to the pattern documented in NHTSA Investigation PE13-017. The vehicle has not yet been inspected by Hyundai but is available for inspection. Incident occurred on [XXX], while driving from Monroe, Louisiana, to Atlanta, GA, shortly after departure. The failure created a serious safety issue, forcing us to stop at a Home Depot and perform emergency repairs using tarp and Gorilla tape to secure the roof and continue our trip safely.

During a recent accident, the driver pressed the brakes but they did not respond, almost as if they locked up. Police at the scene noted there were no skid marks on the road, suggesting the brakes never engaged. The vehicle suffered major side impact damage, including broken windows and crushed passenger-side doors, but none of the airbags deployed. This raises serious concerns about a possible brake system failure and airbag non-deployment defect. The vehicle has not yet been repaired and is available for inspection. Police have reviewed the accident, and the insurance company has also seen the vehicle, but no mechanical inspection has been completed by the manufacturer. There were no warning lights or error messages prior to the failure. The safety of the driver and passengers was put at risk because the car could not be stopped and the airbags did not deploy to provide protection.

Fuel injector failure. Car was losing power completely when pressing the gas pedal then would suddenly catch and go again. Then go very slowly with little power, almost got into an accident because of the loss of acceleration. They replaced the fuel injectors and it is now happening a second time with the check engine light coming on again. A RECALL NEEDS TO BE MADE! SEVERAL OF THE SAME COMPLAINTS ON HERE!!!!!!!

Unbearable Sound While Driving the Car, Causing Ear Numbness and Safety Concerns I purchased a certified pre-owned vehicle from the dealership with the expectation that it would be free from defects. On the very first day, during the drive back home, the vehicle began making a persistent rattling noise that was both distracting and concerning. The sound was so severe that it caused ear numbness within just a few minutes and made it difficult to concentrate on driving, raising serious safety concerns. Upon arriving home, I immediately contacted the dealership to report the issue but received no positive or constructive response. I reported this matter to Hyundai Motor America Customer Service on April 1, 2025. It has now been almost five months, and they have been unable to resolve the issue and mentioning its cosmetics defect. Therefore, I am reaching out to you to address this safety concern and request that precautionary action be taken against Hyundai Motor America, USA. The noise and vibration are so extreme that ear numbness occurs within 2–3 minutes of driving, making the vehicle unsafe to operate and safety concersn. Thanking you.

The vehicle is currently in the shop due to safety concerns involving malfunctioning exterior lighting and a serious incident of the vehicle entering limp mode. 1) With automatic headlights activated, all exterior lights shut off while driving at night, posing a significant safety risk. 2) During daylight hours, the automatic headlight system inconsistently toggles between different lamp settings, switching off and on erratically. 3) While attempting to turn left during morning rush hour traffic (on a 40 mph road where vehicles often travel 50+ mph), the vehicle entered limp mode upon acceleration. It bogged down in the middle of both lanes, unable to exceed 13 mph, placing me in a highly dangerous position. After pulling over and leaving the vehicle off for 5 minutes, the issue temporarily resolved upon restart. 4) The vehicle is stored in a garage, and following the limp mode incident, I received repeated “door unlocked” notifications every 30 minutes from 2:30 AM to 5:30 AM, though the vehicle had not been accessed. These issues are of serious concern and appear comparable to conditions outlined in Recall #149 and Recall #236, both of which address similar malfunctions related to exterior lighting and powertrain performance. VIN# currently is not within the recalls.

While driving on highway going 65 MPH my car 22 Hyundai Tucson SEL dashboard lights turned red and shut off on the highway with no warning, was not able to put in park for 10 minutes. My safety was put at risk, the vehicle stopped mid drive on the highway with other vehicles. Dealership has not fixed or looked at the issue.

The fuel injectors failed on this vehicle, the vehicle’s engine light came on as I was driving and I took the car to the dealer where I purchased it from. The dealer told me.what the issue was and that they needed to keep the car because it was dangerous to drive.

I am submitting this complaint due to repeated and dangerous fuel injector failures on my 2022 Hyundai Tucson. This is the third time this issue has occurred in less than three years of ownership. •First incident: My vehicle broke down on the side of the road while I was 10 hours away from home in Florida. This left me stranded and required towing and repairs. •Second incident: The fuel injectors failed again, though fortunately closer to my home. •Third and most recent incident: The same issue happened again, this time with my wife driving—a major safety concern. We purchased this vehicle specifically to avoid breakdowns like this and for the safety and reliability it was supposed to provide. This recurring failure is unacceptable for a newer vehicle and poses a significant safety risk to my family and other drivers. Fuel injector failure can lead to stalling in traffic or on highways, increasing the potential for accidents. I urge NHTSA to investigate this matter, as it appears to be a systemic issue with this model and could lead to serious harm if not addressed.

The car keeps loosing power when it is over 90 degrees outside. On my way to work in the morning it has plenty of power but on my way home around 5 or 6 PM it struggles to gain speed. I’ve already had all the fuel injectors replaced so I don’t think it is related to that. It mainly happens when I slow down but not to a full stop around 20 MPH. Then it struggles to accelerate after that.

My fuel injectors has been blown and Hyundai will not replace all 4 when one goes out. So I have to keep going back up to the dealership to get it fixed each time. They always blow on the highway. The first time I was doing some distance driving from Columbus, OH to Dayton, OH. Then the other time happened when I was on the highway during rush hour traffic. There were no other warnings before this happens. It just happens and the engine light comes on as the steering will begins to shakes like crazy.

The vehicle's brake system intermittently fails after driving over bumps or uneven roads. The brake pedal becomes soft and unresponsive, and the vehicle continues rolling forward for several seconds before the brakes finally engage. This has happened repeatedly while driving home from work. On one occasion, the vehicle rolled through a red light and I had to swerve into oncoming traffic to avoid a collision. This issue first became noticeable in 2022 and has worsened over time. It puts both my safety and the safety of others at serious risk. There are no warning lights or error messages before or during the failure. The vehicle is available for inspection upon request. Independent mechanics have confirmed that brake pads, rotors, and fluid levels are in good condition. They suggested the cause could be air in the brake lines, a malfunctioning ABS system, or a faulty master cylinder—all potentially covered by the manufacturer’s warranty. The manufacturer’s service center initially refused to inspect the vehicle without an upfront diagnostic fee and only offered assistance after I escalated the matter through repeated complaints. The service director later described the issue as “unsettling but normal,” which is not accurate according to independent professionals. The problem has not been resolved and continues to occur regularly. I am requesting that this be formally investigated as a potential safety defect.

I’ve already had my fuel injections changed about 20,000 miles again and my car is starting to stall again check engine light on again seems to be same issue now my car is no longer under warranty. I don’t seem this problem on the recall list but this is not a problem I want to have every 20,000 miles.
