2022 Hyundai Tucson

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.

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.

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.

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.

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.

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.
