2022 Hyundai Tucson Powertrain & Transmission Problems

Bought the 2022 Hyundai Tucson. It was driving perfect no issues then I hit 52,000 miles and the check engine light illuminated. The vehicle started sputtering and idling hard like it wasn’t getting fuel when the gas was pressed. I was on the interstate and the vehicle wouldn’t go over 35mph. Now the check engine light illuminates off and on when it feels like it.

I am dealing with this issue where I am getting fuel injector issue and getting cylinder 3 misfire and air fuel imbalance code. It comes and goes. I spent 1500 bucks flushing fuel system and replacing spark plugs and coil. But the issue is still there! i changed the battery and got it to dealership they said they could find the issue. I was on freeway going southbound near exit 34 when the car starts shaking and I lost acceleration

When My wife was driving our car on the highway today to work, the car suddenly threw a "check hybrid system - pullover safely" light when she was at highway speeds. She was able to luckily pull over quickly onto the shoulder before the car completely powered down. This is incredibly dangerous. She had to click on the reset 12 volt hybrid battery button in the car to get it started again but the complete loss of power at highway speed was very upsetting.

I am submitting this complaint due to a potential safety-related engine failure that occurred while my vehicle was under dealership repair. My vehicle was dropped off at Huffines Hyundai on October 2, 2025, for a fuel injector issue and has remained under the dealership’s exclusive possession since that date. I have not driven or had access to the vehicle after drop-off. During the repair process, I was informed by dealership staff that an injector was seized in the fuel rail and difficult to remove. Although the injector replacement was documented as a short repair, the work was delayed and completed on October 16, 2025. Immediately following this repair, on October 17, 2025, the engine was documented by the dealership as having low compression. I was not notified of this condition until October 27, 2025. The engine damage occurred while the vehicle was under dealership control and immediately following a repair involving seized components. The diagnostic documentation provided to me is incomplete and does not include compression PSI values or supporting data. I am concerned that improper repair or handling may have caused internal engine damage, resulting in a condition that could lead to engine failure or unsafe operation. Due to the circumstances and lack of transparency, I do not feel the vehicle is safe to operate and am concerned about the risk of engine failure.

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!!!!!!!

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.

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.

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.

Fuel injectors. It is available for inspection. (Please!)This is the second failing of an engine, fuel or Powertrain issue. The car was in motion and suddenly just lost power. The first time it occurred about a month after purchased brand new in 2022, the car was coming from a stop light into the middle of an intersection. Driver was thankfully able to glide to side of road since it was early morning and had it towed to dealership. Second time it happened approximately 2 1/2 years later May 29, 2025, the car once again lost engine power at an intersection. Driver, again ,was in a fortunate position to glide off road from a right turn lane. If driver had been in left lanes going speed (55) this would not have ended as well. The car would not restart. Car was towed to dealership. The dealership confirmed that this was a known issue and there was a TSB out. However, there are no kits available to fix it at the moment. And we have no time frame for getting our car back and they have not provided a loaner. The vehicle has only been inspected by the Hyundai dealership. There were absolutely NO warnings before either incidents. However, once the car was in possession at the dealership, we received a phone call from Hyundai BlueLink saying we had a Powertrain issue, which did not make sense since our car had been sitting for two weeks unserviced. If this was related to the same issue they were at least two weeks late. Dealership did not confirm Powertrain issue or how anything would be resolved.

While merging onto [XXX] in Southington, CT, the vehicle would not accelerate past 25 MPH which is very dangerous for merging onto an interstate highway. Luckily, my wife was able to safely pull over onto the shoulder. We shut the vehicle off for a minute, restarted it, and have had no problems since. There were no warnings, and no check engine indicator was displayed. I'll contact the dealer this month at a regular maintenance visit. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2022 Hyundai Tucson. The contact stated that while parked for approximately an hour and the front driver seat unoccupied, the contact's granddaughter climbed into the front seat from the rear to sit with the front passenger occupant and accidentally depressed the drive (D) button and the vehicle began rolling forward. The vehicle crashed into another parked vehicle. There were no injuries and no police report filed. Additionally, the contact stated that she attempted to switch to each gear and the vehicle's brake did not need to be applied to shift gears. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 28,000.

2022 to hyundai tuscon now with the third cylinder misfire due to faulty fuel injector. This can be inspected upon request. Upon second occurrence, requested all cylinders be replaced and advised could not do this under warranty. Second filing to NHTSA. This incident put myself and other drivers at risk. I was driving on a highway and the cylinder misfire occurred resulting in check engine light and vehicle going into limp mode and inability to drive more than 30-40 mph. The entire vehicle violently shakes and loses power with this misfire. In the previous occurrences , could not accelerate beyond 20 mph. I could have been rear ended or caused a serious accident on the highway as a result of Hyundai faulty fuel injectors and cylinder misfires. My vehicle has now been seen 3x for the same issue and replaced by dealer. There were no warning signs prior to the failure of the fuel injector resulting in cylinder misfire and loss of power and inability to accelerate. This is a very dangerous faulty component of this year make and model- it is a known issue. Still no recall. I have a "new" car that puts me in danger every 4-6 months when I lose power in my vehicle with no warning or cause except from faulty parts. This faulty part is going to cause serious injuries/accidents if it is not addressed.

The safety alert system on the vehicle alerted us five different times that the vehicle needed to be parked and checked immediately due to a Powertrain issue and each time we took it to the dealership because it is still under warranty at 47,984 mi. This last time they have had it for just over 3 weeks and said there are three or four of the same vehicle with the same issue that they are trying to get parts for. This is not coming up as a recall, but it has been an issue with safety because it tells us to immediately Park the vehicle and it loses engine power when accelerating which is very dangerous for navigating traffic. Insurance has not been involved as it is on warranty and there has not been an accident because of this issue yet. Please look into this because we do believe there should be a recall on this model. I know other people who are having the same issue with the same type of vehicle but on the Santa Fe. The issue starts out where they say it's just a gas cap. But then switching out the gas cap doesn't fix the problem.

Within the first year of purchase, my power train system has beeb throwing codes. I took it to the dealership where they assured me nothing was wrong. My fuel injectors then gave out. The dealership replaced them and told me “yes these things are faulty and we see it a lot”. After replacing it, they did not seal the fuel injectors, causing gas to gush out and set my car to smoke. I was ill from inhaling gas fumes for days. They took accountability and said that the injectors were defective in the vehicles and that they would once again fix it. I am not experiencing further engine issues which they do not know how to diagnose. My car is a 2022 purchase from the lot. The engine is defective and Hyundai is negligent. They admitted they were aware of the injector issue but didn’t do much to correct this. After corrected, they almost had my car set on fire from fuel pouring on the engine.

At the end of May 2024 my car was diagnosed with a faulty fuel injector that caused sputtering and problems accelerating. I was driving on a busy freeway when my car began to shake and sputter and lose power. A check engine light came on when the car first started to shake and sputter. I was able to pull off the freeway but, in an area, where I was unfamiliar. I was able contact family nearby who assisted me in driving the car slowly to a Hyundai dealership about 15 miles away. This happened on a holiday weekend and I had to get a rental car as the dealership was unable to service the car for several days. The dealership diagnosed the car as having a faulty fuel injector and a new fuel injector was installed. On December 5, my car again started sputtering and shaking and had problems accelerating. It needed to be towed to a Hyundai dealership about 50 miles away from my home. I am currently waiting for them to diagnose the problem.

Dealership tried to fix vehicle multiple times and failed. Would be considered a Lemon but is over 3 years old.

Driving 78 mph on the highway, when the car stopped it accelerating, dropped to 67, pulled to shoulder. Car would not restart. Towed to dealer and was told the fuel injector failed and was flooded engine. Check engine came on with code DTC P030400 DTC System POWERTRAIN DTC Sub System EMS

Vehicle has experienced, unexpected, slight and brief, acceleration 3 times at highway speeds up to 60 mph. The 4th incident was an uncontrolled acceleration when parking behind another parked vehicle. Car accelerated into the backend of parked vehicle. Operator was at a complete stop and needed to pull forward a few feet. They took foot off of brake and lightly pressed the gas peddle. The car unexpectedly surged forward hitting parked car. 1 day later we received an email from Hyundai Blue Link stating that "a possible condition with your Engine Control System has been detected" and recommends bringing in for service for a full system check. Both cars were damaged and Tuscon had to be towed to a repair shop.

While driving the car the engine died, locking up both the gas and brake pedals. The car had to come to a stop on its own, my wife could not depress the gas or brake to stop the car. She was going through an intersection and narrowly avoided a major accident! The battery light came on, the check engine light and the car started to fill up with a smell of burning plastic and gas. When trying to turn the car back on after turning it off it would start with a major shake and bang then turn back off. All warning lights stayed on. Battery was fully charged still. Autobody shop found engine issues in their pre scan before sending it to Hyundai to warranty it as it only has 6,626 miles and is 2 years old. There was a warning of low battery while we were on vacation and the car was sitting for a few days. And a sluggish start when it sat for few days like the battery was low, but it wasn’t based on the volt meter.

I have a cylinder misfire related to known issues with this product and any dealership affiliated with warranty work are months out, there are no backup vehicles and Hyundai will not take any action until they are diagnosed. We have no backup vehicle and my wife was almost hit. There was sudden power loss of the vehicle and it is a safety concern. No reimbursement for rentals or alternate solutions provided
