2022 Hyundai Tucson Engine

I have had 2 failures of the EGR valve. The first was covered under warranty. Hyundai is refusing to cover the second repair even though I think it should be covered under the 80,000 mile federal emissions warranty. The vehicle currently has 73,000 miles.

The contact owns a 2022 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, there was a misfire in the engine, and the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed with engine cylinder failures. The contact was informed that the cylinders needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 55,000.

While operating the vehicle, the engine shut down. Complete loss of power. Engine would restart, stall and then not restart. Vehicle immobile. Vehicle towed to dealership since could not be driven. Strong smell of gasoline.

2022 Tucson (NX4, Alabama built) 2.5L Engine experienced a catastrophic failure leading to Hyundai dealer diagnosis that "Cylinder #3 is not contributing properly," which requires a full engine replacement. The vehicle is currently located at home and is available for inspection upon request. The engine scuffing has resulted in a severe loss of power contribution from Cylinder #3, leading to potential for sudden engine stall or complete loss of motive power while driving. If the engine seizes or stalls at highway speeds or during a critical maneuver (e.g., merging onto a freeway or turning across traffic), it creates an unreasonable risk of a rear-end collision or a catastrophic accident, endangering both the driver and others on the road. Furthermore, the internal mechanical failure creates a significant FIRE RISK due to potential oil leakage onto hot exhaust components. The problem has been confirmed by Hyundai Service Center in El Paso, Texas and three independent service centers in Arizona and Texas. All four assessments concluded that the vehicle requires a full engine replacement due to severe internal damage. Inspected by Hyundai Service Center in El Paso, TX. Despite confirming failure, Hyundai refuses to provide critical diagnostic data (Power Balance Test, Endoscopic Inspection, DTCs) and the determined root cause. This refusal hinders warranty transparency. The Check Engine Light (CEL) did not illuminate. Symptoms appeared late September 2025 at approximately 88,000 miles (audible engine noise/scuffing, rough idle, significant power loss). This failure at non-typical mileage demonstrates a severe internal defect and a safety system malfunction (failure of the ECU/CEL to adequately warn the driver). Note: Dashcam video documentation of the engine failure symptoms (audible noise and power loss) is available and can be presented to investigators upon request.

I am submitting this complaint regarding an ongoing and dangerous issue with my 2022 Hyundai Tucson involving repeated fuel injector failures that have caused the vehicle to stall and lose power while driving, without any prior warning indicators. The first incident occurred in October 2023, at approximately 16,000 miles, when the car suddenly died while I was driving. There were no warning lights or signs of a problem before the stall occurred. The vehicle had to be towed to the dealership, where they replaced two fuel injectors. Just two weeks later, the same issue happened again—the car died while driving and was towed back to the dealership. The remaining injectors were then replaced. Unfortunately, this problem has continued. In November 2024, at around 26,000 miles, the vehicle again stalled while driving, with no warning, due to another fuel injector failure ( more failed injectors). Most recently, on October 18, 2025, with 31,000 miles on the odometer, my Tucson lost power and died while I was merging onto an interstate—once again with no warning or alert of any kind. I am still waiting for confirmation of how many injectors have failed this time. This is an extremely serious safety hazard. Losing engine power unexpectedly, especially while merging into highway traffic, puts both the driver and others on the road at significant risk of a collision or serious injury. Despite multiple occurrences, Hyundai has not identified the root cause of the injector failures and continues only to replace the faulty parts, which clearly does not resolve the underlying issue. It is unacceptable that a relatively new vehicle would experience repeated fuel system failures of this nature, and it is clear that there is a systemic defect affecting safety and reliability. I urge the NHTSA to investigate this issue to determine whether other Hyundai Tucson owners are experiencing similar failures and whether a recall or safety action is warranted.

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..

Vehicle has just over 20,000 miles, and all four high-pressure fuel injectors have been diagnosed as “bad”. This is a very common issue reported on the Internet for 2022 Hyundai Tucson vehicles. Vehicle misfires and loses power with check engine light.

The contact owns a 2022 Hyundai Tucson. The contact stated while driving 60 MPH, the vehicle lost motive power and was pulled over to the side of the road and stalled. The vehicle was restarted 20 minutes later with the check engine warning light illuminated. The vehicle was taken to the residence. The vehicle was then taken to a dealer twice however, the failure could not be duplicated. The contact stated that on the second visit to the dealer, the dealer was able to provide an undisclosed update for the engine. The manufacturer was not notified of the failure. The failure mileage was approximately 8,089.

The vehicle experienced a malfunction in the ignition or fuel delivery system, specifically a misfire detected in cylinder 2 (DTC P030200). This component has been documented by the manufacturer’s vehicle service center as an issue and may be available for inspection upon request. The misfire caused reduced engine power and hesitation during acceleration, posing a safety risk, particularly while merging onto highways or attempting to pass other vehicles. The issue has been reviewed and addressed by the manufacturer dealer service center twice (presently going in for a third time); however, the problem returned each time after a few weeks, with less than approximately 5,000 additional miles driven. The vehicle has not been inspected by police, insurance representatives, or other parties. The "Check Engine" warning lamp illuminated when the failure occurred, accompanied by symptoms of rough idling and reduced performance.

I was merging on the highway when the car bucked and the check engine light came on. I couldn’t drive over 20 mph without the car shaking. I pulled over and had the car towed. The issue was a faulty fuel injector. It was replaced under warranty. I am worried reading online about this problem happening again. My family has owned 4 Hyundais and I’m starting to loose faith in their reliability. This really needs to be recalled.

Fuel injector went out in the middle of highway and vehicle had to be towed after vehicle starting shaking and couldn't drive above 25 miles per hour. This is a known issue by Hyundai in 2022 Hyundai Tucson.

14202 miles on this car with regular oil changes by dealership. Engine is KNOCKING and needs a whole new engine. No warning, no lights, no codes. Is not able to be driven. Had my whole family in the car

I was driving on the highway when the engine would not accelerate. I was stuck in a high speed lane and drivers were on my rear bumper. I could not move over and felt helpless. I pulled off at the next exit and the vehicle was sputtering. I made it home at reduced speed. The vehicle would not start the next morning. I had it towed to the nearest dealership. I was contacted days later and informed that the is a bulletin about power loss due to faulty fuel injectors. Many complaint sites are full of the same problems. I now feel unsafe driving the vehicle on trips. I don't want to get stuck in the middle of nowhere. I am a female senior citizen.

For the second time vehicle has lost power and slowly began slowing down. This time it was on the interstate which almost caused a collision with a semi. It is due to faulty fuel injectors which is a known issue with hyundai.

The contact owns a 2022 Hyundai Tucson. The contact stated while driving at an undisclosed speed, the vehicle stalled. Additionally, an unknown warning light was illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 12,000.

My vehicle wouldn't start.3 warning indicator lights came on. I had just driven my car 4 hours ago and was going to delivery a cake. My car was parked in my garage. I pushed starter but vehicle wouldn't start. Had to push starter several times before indicator lights would shout off. Had to have vehicle towed to dealership on 7/9/23

I am writing to express my deep concerns regarding a series of ongoing safety issues with our HYUNDAI TUCSON 2022 (leased in 2022). We have encountered alarming problems that are affecting the safety and reliability of the vehicle. On July 29, 2023, my husband was driving the vehicle up a sharp incline when the car started shaking/jolting and abruptly shut off. This resulted in a highly dangerous situation as the car began to roll back. He was unable to restart the vehicle, and it had to be towed to the nearest Hyundai dealership. It took over a week for the dealership to address and rectify the issue...so we thought (see below). Also, please note that there was smoke coming out from the exhaust when the tow truck came. It looked like smoke from a flame inside. Fast forward to November 8, 2023, the vehicle was experiencing the same issue as before: continuous shaking/jolting, and the vehicle abruptly shut off once again... stalling in the middle of a highway. A police officer saw what happened and helped my husband relocate the vehicle to the shoulder of the highway to avoid oncoming traffic/collision. He waited with my husband as he kept trying to get the vehicle to turn on. After 30 min, he was able to get it back on. The "check engine" light was illuminated. My husband drove home while the car was still shaking/jolting. We plan to, once again, have it towed to the nearest Hyundai dealership today. We were told the issue had been "resolved" from the last time this happened in July. Clearly, it was not resolved and I feel this vehicle should be recalled. These recurring problems are deeply unsettling for a vehicle that is not even two years old. Given the repeated and unresolved safety issues with this vehicle, I am concerned for the safety of myself, my family, my unborn child as I am expecting and other road users. I would like to request your immediate attention and intervention to address these problems effectively.

Check Engine Light comes on randomly.

The contact owns a 2022 Hyundai Tucson. The contact stated while entering the highway and depressing the accelerator pedal to the floor, the vehicle failed to accelerate over 50 MPH. The contact stated that the check engine warning light was illuminated. The contact stated that the steering wheel and vehicle was shaking abnormally. The contact continued driving to her destination. The contact took the vehicle to the local dealer the following day, where it was diagnosed with needing fuel injector #4 to be replaced. The vehicle was not repaired and continued to experience the failure. The contact took the vehicle to the local dealer the following day, where it was diagnosed with needing the remaining fuel injectors to be replaced. The vehicle was not repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 42,000.

System Failed: Shut off in traffic. Vehicle can be inspected upon request. Safety risk: Potential for collision. Input from Dealership: Dealerships error code/diagnostic code was P213800. Reset system and recharge battery. Warning lights came on at the same time as the car shut down. One month prior check engine light came on, but car was operating normally. Dealership ran diagnostic test which did not indicate any issues. The suggestion was to tighten the gas cap.

Engine light is on at 6,000 miles,they fixed but on again a month after repair.

3rd time Engine Control System code has appeared with complete engine loss the 3rd time. Dealership reset the other times I had called AAA to have it towed to dealership. Car was undrive able. Shaking with no RPM. Dealer ship won’t look at it till the 24th of August 2022

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The engine will not start despite having the key fob with live battery on my person. 2. How was your safety or the safety of others put at risk? I was stranded 3 times in a week in dark public parking lots with limited cell reception. I had to abandon the vehicle to get to a warm, safe location, and as a single woman, did not feel comfortable staying with the car while other cars were loitering at night. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? The car has been with the dealer for 6 days now and they have not been able to replicate the issue and it has happened to me 3 times in one week. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, there doesn't seem to be any rhyme or reason why the car won't start. After a few hours, the alarm sometimes goes off, and the system resets, allowing me to restart the car. Given this car has a push button start ignition, there is no mechanical way to crank the ignition to start the car, so I am left with no recourse. The last time this happened, I had it towed to the dealership because even after waiting 3 hours, the system did not restart and I had no recourse.

At highway speed engine began stumbling and shaking car and stalled the car within 5 seconds bring car to halt. Engine would not restart properly, would not settle at idle rpm with rapidly inconsistent rpm shaking the car and then stall within 5 seconds. Any attempt to place car in drive immediately stalls car. After attempting 50-60 bump starts to get car off road the check engine light and error message about engine control system error eventually showed. Hyundai towing refused to take inoperable car to dealership for warranty repair of 1000mi car, instead left it at our apt parking lot. The engine failure left the driver and other motorists in danger as unable to move stranded car off 50mph busy main road on cold dark snowy evening. Dealer reports they are “swamped” with repairs and cannot see an inoperable car for at least 2-3 weeks and no loaners or rental could be provided. There were no warning lights or warning during initial stall or subsequent restarts. Error message and check engine light did not light until attempting 50-60 bump starts trying to get car off road and a hazard to occupants and other motorists.

I have owned the car for 5 months. But have had the ability to drive it for four and a half of them. This vehicle has put me and my family at serious risk multiple time. The first incident my car would not accelerate when I drove onto the highway and it would constantly stutter when I would attempt to accelerate again causing a truck to almost rear end us. The following day my vehicle had a hot engine temp. I pulled over on the highway to an empty antifreeze tank. Refilled it multiple times to only have it empty out and completely shut off while we were driving! Took it to the dealership where it took them 2 weeks to return it. When I asked what the problem was they said they don't know they just replaced it. 3 weeks later ( 5/28/22) while driving back from an event the car starts making a clunking sound and shuts off on me 3 times on my way home with my 9 and 7 year old in the back. Thank goodness it wasn't on the highway! It's now 6/1/22 and I still haven't heard anything about my vehicle! This death box has put my family at risk 5 times. I would strongly advise against buying it! The manufacturer could care less. Luckily the lemon law protects them against people who's lives are constantly put at risk while driving there vehicle!
