While driving uphill, the car lost power, beginning to spurt and stalling. Then the car was not able to accelerate while car kept spurting and stopping. It was a dangerous situation as this happened while we were driving, in the middle of the road, while going uphill. Thankfully it was at night and there were no cars behind us but if there was we would have clashed into it. Towed the vehicle to the dealership and was informed that the same year TUCSON came in the night before with similar problems. It appears that there is a pattern to this safety concern. Please take action before someone gets hurt. Car shutting off like this while driving poses safety concerns for drivers and all the people around it. Even with fix, I don't feel safe driving unless I see actions taken by Hyundai to solve this apparent issue with powertrain/engine.

Car lost ability to accelerate and was shuddering for the second time. My personal code reader pulls up codes P0191 and P0303. Engine misfire. Second time since June28,2023. Bought the Hyundai Tucson brand new in December of 2021. First time car lost acceleration and was shuddering on the interstate with my toddler son and pregnant wife stranded. The second time was tonight, October 30th, 2023. I was in the car with my still pregnant wife and toddler son.

On 10/17/23 I was driving about 55 MPH up a hill when the vehicle began to decelerate rapidly and would not accelerate. The vehicle was shaking and jerking and would not go over 34 MPH. I was fortunately in the right lane and was able to make a right turn into a long merge lane. I turned off the car and tried to start again, and it began shaking uncontrollably while making a strangled noise. I pressed on the gas and smoke began to exit the exhaust. I turned the vehicle off again. I waited about another 5 minutes to try to start the vehicle and was met with the same scenario as above. This time, all the lights on the dashboard turned on; car battery, engine, oil, etc. The brake pedal was also locked up, unable to depress to put the car in neutral. Had the car towed to the dealership and the service advisor indicated it was most likely the fuel injector. He started the vehicle and the same strangled sound and shaking started. The cabin quickly filled with the smell of gasoline. The service advisor stated that it would take maybe a week or more before the vehicle could even be seen as all service centers in the area were understaffed and backed up. No rental/loaner car is allowed to be issued until the car is diagnosed by the technicians. Earlier in the day, the Bluelink app was not functional to remotely start the vehicle. Attempted to remote start the vehicle from two devices, no success. Called Bluelink and the rep had me delete and redownload the app, reset the system in the car by pressing the small reset button, and even tried to send a remote start request from her end and was unsuccessful. She stated a ticket for further assistance is needed. On 10/19/23, the Bluelink app notified me of an issue in the car: DTC P030200 POWERTRAIN. I have read other reports of this occurring in this vehicle. Huge safety issue, especially when on highways. Still waiting on Hyundai to service the call. I hope all fuel injectors are replaced instead of one.

1) Transmission: while driving car jerks. when I-??m accelerating from a stop sign or stop light the wheels kind of feel like they-??re spinning/shaking and driving over gravel when I accelerate, before it actually starts and shifts gears. Car accelerating but not moving. 2) Not safe. Almost hit other cars around and people. 3) Dealer confirmed and replacing with new transmission. 4) No warning signs

- Plano , TX, USA

While driving the check engine light comes on and the car loses power and starts running very ruff and almost stalls at times. This is the second time this has happen in 3 months, last time they replaced a fuel injector. I look up the problem and it seams to be common problem with the 2022 Hyundai Tucson.

- Moreno Valley, CA, USA

System failure: Powertrain/transmission. Safety: Driver is stranded without vehicle four hours from home. Driver and passenger could have been rear-ended when vehicle stalled and slowed. Confirmed and Inspected: Vehicle was towed at Hyundai's expense to local dealership but cannot be examined for 9 days. Warning: Engine light came on and vehicle was immediately parked. Symptoms: The 2022 Hyundai Tucson was purchased new on April 14, 2022, and has only 13,800 miles on it. Early in September 2023 when accelerating, the tachometer went way too high; and the vehicle stalled like it was in neutral. Four times on September 15, 2023, at 60 MPH, the vehicle jerked like it was going over rough pavement and fish tailed in the rear end. On September 16, 2023, at 60 MPH, the vehicle again acted like it was on rough pavement. When slowed for in-town traffic a few minutes later, the vehicle began jerking and shuddering constantly at around 30 MPH and would go no faster. The vehicle was barely able to go up a small incline, and the engine light came on. The vehicle was parked immediately. Today, September 18, 2023, Hyundai Customer Care towed the vehicle, at its expense, to the closest Hyundai dealer four hours away from where the driver lives. The local dealership cannot look at the vehicle until September 25, 2023, at 2:30 PM. The dealership where the vehicle was purchased refused to tow the vehicle at its expense and would only say "We can't do anything until we look at it." The dealer stated the vehicle has a misfiring cylinder caused by a No. 4 fuel injector. The fuel injector has been ordered, but the vehicle is still at the dealership.

July.2023: Check Engine Light On ; It came as we were driving on the highway. Acceleration was sluggish due to this issue. Error code indicated that 1 of the 4 engine had issues. Escalated the issue to Hyundai Customer Service. Issue was resolved during first week of Aug.2023. Sept.2023 We were driving on the highway and Check Engine Light came once again. It was late at night. The acceleration was sluggish and managed to drive to a nearby hotel. Contacted Hyundai Customer Service. 2 out of 4 cylinder had issues (replace rotor, wiring etc.,). Dropped the car in a Hyundai dealership (Urbana, IL). Rented a rental car to drive back to MI. Given the recurring cylinder issue, Hyundai Customer Service is NOT willing to accept the issue with Engine. 2 out of 4 cylinders had issue. Remaining 2 cylinders may have similar issue. Given the issue, quality of 2022 Hyundai Tucson Engine design and build quality is a MAJOR issue and RISK for customers. Should you be driving in a freeway, acceleration will be sluggish and can cause major accidents.

When I-??m at a dead stop, and start to drive off, there is a jerking at around 13 miles per hour. I believe it is when it is shifting from first into second gear. It happens often, but not all the time. This happened when I first bought my car, and I was told that the car has to get to know me. I thought this was true, because it seemed to have stopped at some point for a while. Now it is doing it again, but more dramatically. The jerking is very obvious. Also there have been about 5 times when the car revs by itself when I am in the 40-??s. I am not pressing heaving on the gas, I am just driving, and it sounds like it slipped out of gear for a second and the car is revving, and then it just goes back to normal.

- East Hampton, NY, USA

On 9/3/23, driver was waiting at a stop sign to turn left. When driver accelerated into the highway, there was no power and the vehicle would only go 5-10 mph. Warning lights came on to check the hybrid system with the HEV indicator light. Driver pulled over. Restarted car and engine was stuttering. Was able to drive a few miles to a safer location. Started car on 9/4/23, again it had a rough start. Driver waited until the vehicle sounded normal. The vehicle immediately lost power and could not accelerate when on the main road. Called Hyundai and they were unconcerned. We are in remote Alaska, 250 miles from a dealership. Because it happened on a holiday weekend, we have been unable to contact the service department yet. Vehicle is available to be inspected. Safety is a huge risk because the car suddenly stops propelling forward. I'm afraid we will get rear-ended because of the sudden loss of power. It is a danger to ourselves and others. I'm also concerned that we will be stranded because the car has to be stopped when this occurs. We were supposed to be enjoying a trip for a week, and now we don't trust the vehicle and will likely need to go home early and lose hotel costs. This issue will wind up killing someone because there are reports that these Hyundais are stopping in the middle of the highway. Please hold Hyundai accountable.

- Anchorage, AK, USA

The affected part is the engine and/or power train, the engine light constantly stays on. The acceleration decreases and unable to drive over 40 mph. These parts were inspected by two different car mechanics at Hyundai Car dealerships, Alexandria, VA (April May 2023) and Waldorf, MD, (June -July 2023) which they say was the gas cap. After getting a diagnostic the reading was P0 301. On August 22,2023 at 9:30am took the car to mechanical service at Hyundai In Waldorf, MD they concluded it was the gas cap, again, today the engine is on again.

Constantly having warning lights on, car jerking into other lanes, emergency braking randomly, brakes went to the floor and car propelled through an intersection

- Hamden, CT, USA

Car intermittently will loose power (shortly after commencement of driving). This will remedy itself by shutting off engine and restarting. This has happened 4 or 5 times within the fist 3,000 miles. This is a vehicle and traffic SAFETY issue that could cause lives!

- Orchard Park, NY, USA

The car shook and then lights and alarms went off indicating something went wrong with the hybrid system. The car stopped accelerating, would shake, and then accelerated no more than 10 mph. It was absolutely crazy! Luckily, the highway that I was traveling on was not a busy one at the time because all I thought was this could have been a major accident if on a fast moving freeway. I managed to pull over and started reading online about this issue occurring with other customers who purchased the same or similar vehicle. So, I found a post and had shut the car off for 5 minutes, then restart and sit for 10 minutes, and then the car should work. It did! However, during the time of waiting I did reach out to the dealership and they said if the car is working there is nothing they could do. So, I assumed it was safe to use travel to work for a meeting and set up my classroom for the start of the new school year. On my way home from school, the issue happened again. I immediately contacted the dealership and was able to get the car to them. They started running diagnostic tests and currently have the vehicle on hand. However, I don't really feel safe now with this car given the circumstances. What if this should happen again? What if this happens to me or someone else who is traveling on a busy highway and it causes injury or even death to an accident. The engine light came on, battery light flickered on and off, the car shook, the car's HEV system warning was going off, etc. Please help and look into this matter. I do not have any documentation of repair as the car currently sits at the dealership, but I was so upset thinking about what could have happened and felt the need to report the issue.

-There are 3 problems. The 1st and most dangerous, is a combo of the engine, transmission, and fuel system. The 2nd is malfunctioning sensors. The 3rd is water leaking in under my glove box onto the floor mat. The car upon 3 different occasions has stopped accelerating in the middle of traffic. 1st: the car would not go past 30mph and it stuttered/ shook. I parked and turned the car off, but 5 minutes later it reset and ran "normal". The 2nd time in Dec 2022, I was on Annapolis Rd.(Maryland) at about 10pm while alone. It would not accelerate past 35mph, the check engine light came on, and the engine/transmission started shaking and stuttering. I was almost rear ended so I pulled over. The next day when I called the dealership, the car had once again reset itself. The dealer brushed me off, said the cars are so computerized that if they couldn't replicate it they couldn't fix it and said they were backed up on appointments. The 3rd time, the car stopped accelerating on the beltway as I was taking my exit home, almost got rear ended, as I was pulling off the exit and trying to pull over the car started producing white smoke and the smell of gas, the engine control system (1st time of these 3 instances) alerted to shut the car down. The gear shift would not work properly while trying to shut it off. It massively leaked gas out of the vehicle and into the oil/ oil filter. While broken down, multiple cars almost ran into it as it had shut down after a major intersection. The car almost exploded/ caught fire. It was towed to an autobody shop to be inspected as I did not trust the dealership. No repairs were made. Only an oil change and new oil filter. There was a random misfire code. But ran normally once reset. There was no damage that he inspected and called it a Lemon. The dealer has the car, and has yet to diagnose it or give me a loaner. All regular maintenance performed and all system checks have come back normal up to this point.

This Tucson Limited has 3500 miles on it from purchase last September - 2022. Less than 1/2 mile from home and accelerating to about 35mph the engine lost power where speed reduced to about 20mph, acted like air intake was being choked. Did not see any caution lights on the dash. I coasted for 30 feet - luckily the street had no traffic - and the engine began to operate normally. I continued traveling about 2 miles and it happened again but briefly - still on town roads, continued driving and it happened once again climbing a hill. Made it part way up and power came back. Continued driving to destination another 2 miles, parked the car for about 45 minutes, came back, car started normally, drove home without incident. If this occurred on a busy road or highway I'm sure the trip would have ended in an accident. I believe this is a dangerous fault. Car is in for service now and they say the ECU was updated. Hope that corrected the problem as my wife refuses to drive it without some confidence level improvement.

I am very distracted with this NEW car. This is the second time this has happened to my brand new Hyundai Tucson PHEV 2022. I was reversing on a slope, I changed gears to Drive, and then suddenly my car got stuck and stayed on neutral for no reason. Can-??t turn off the car, or even change gears anymore. This is terrible! Please fix my issue Hyundai! The first time this happened was 3 months after I got my car when I was camping and I had to have it towed to the dealership. The Hyundai team said there was nothing wrong and said it wouldn-??t happen again. This is the second occurrence now within owning this new car and it hasn-??t even been a year yet! This is not safe and on top of everything I ended up blocking up an entire street because the car could not be moved. Not only did I have to spend my time but also my money dealing with these issues. Now I have to deal without a car and I dont feel safe going anywhere with this car. i need this to be fixed asap. it is my new car and i shouldnt have to deal with this type of stress. Please help me in getting these issues resolved. I do not feel safe going anywhere with until I know that this won-??t happen again. I am well within the power train warranty and well within basic warranty of my car.

My pregnant wife-??s 2022 Hyundai Tucson lost engine power while on the interstate with our 16 month toddler in the car. Luckily she was able to get off the interstate and into a safe parking lot. The car only has 23000 miles and has been kept up with Hyundai-??s scheduled maintenance from their dealership. The engine is knocking and experiencing rough idle. Once I arrived I was able to read that there was an engine cylinder 2 misfire. About an hour later the -??MyHyundai-?? app sent the same error codes. It took the tow truck driver 15 minutes to go 10 feet to the flat bed as the car would turn its self off. Incredibly dangerous for a car less than two years old. I hate that I might-??ve gotten my wife and son such a dangerous vehicle.
