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.

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.

I bought a ‘22 Tucson Hybrid in Sept of ‘22. Upon delivery there were issues w paint & a dent on the rear qtr panel. The bigger issue however, is disconnect in communication between the EV motor, gas engine & transmission. All work is done @dealership and well maintained. History of EV over 8 months: @1000 miles noise under vehicle began. Dealership inspected, all checked out. The dealership has done all servicing as scheduled. From 1000 to 12,000 miles, the vehicle drove best if in sport mode. Sport mode utilizes the gas engine and not EV. When in EV modes, the vehicle runs high rpms or it’s sluggish. It’s never consistent. In some instances; the vehicle will actually stall for 2-3 seconds and kick back on. 1 instance was at a stop light, turning left. Mid turn, gas to the floor, the vehicle stalled for 3 seconds before responding. I was almost hit at 50 mph in the intersection as both motors failed me. The next day, 3 lights came on: An EV, check engine and Hybrid motor light came on, 3 total. My Hyundai app stated: issue communicating EV and Gas motor, EMS communication error. This cleared itself in 36 hrs but I couldn’t drive it safely for a week. I took it to the dealership, everything checked out. 3 days ago @ 17,400 miles, I received a text: Hyundai stated car unfit to drive. DTC code U062300, U111200, U02BB0:Powertrain EMS issue. The techs had it 2 days, fixed it. 3 blocks from dealer, check engine light came on again. I returned it to dealer. I’ve found 32 accounts of these codes resulting in a Hyundai buy-back, new engine, new transmission or settlements. I’m told my EV motor, gas engine and transmission won’t communicate even after software / firmware updates & mechanical changes. I don’t feel the vehicle to be roadworthy and I don’t feel safe driving it, if Hyundai has no fix. I’m told, many sales of this model @ my dealer have the same issues. Bad batch? I paid $47k (car & warr) I’m hoping for a buy back or to get into a Toyota hybrid of = value

Within only two weeks of purchase this new car would suddenly stall in the middle of the road. The computer tells you to pull over. We continued to try and get the dealer to fix this issue, they first ignored us, then they secondly tried and successfully replicated the issue. They said there is no way they can fix the issue. This dangerous stalling in the middle of the road happened numerous times. You will push the pedal all the way to the ground and it won’t go over 20mph. This is a very dangerous issue and these vehicles need to stop being sold. It is very dangerous. We have been left without our money back and without a car to drive for months. We cannot drive the Tucson as it is simply too dangerous and must be towed to go anywhere for salvage.

When driving my car at any speed it will suddenly begin to get sluggish then it becomes unresponsive to me giving it gas and starts to decelerate. When this happens suddenly warning signs on the vehicle go off stating to check the hybrid system and stop the vehicle. When this happens the car then stops functioning. I never know when it is gonna happen. I have been in the middle of heavy traffic and at high speeds stuck in the middle of the road. I have brought it in now four times to different dealerships and contacted corporate and No one can find a problem. I have pictures of the warning signs going off, all I am being told is we don’t find anything wrong when they run their test or try to reproduce the issue, so they can’t help me. This is a very serious and dangerous situation to be driving a car that has and will stall at any given time.

The vehicle is currently at the dealership. I purchased the 2022 hyundai Tucson hybrid limited in April. Have gotten my oil changes done religiously at the dealership. Vehicle is at 22k miles. And had oil change 5 days prior to incident. I was on the way to work and vehicle started to struggle to accelerate, engine began malfunctioning. Vehicle dropped drastically from 80mph Dow to 25-30 mph in short period of time, would have been rear ended if not in right lane already. No warning or previous problems. No warning or check engine lights EVER came on before the vehicle would not drive at all. And was told by the vehicle to “check hybrid system stop safely”. Called roadside and vehicle was towed to dealership. They diagnosed as “the timing chain was ‘missing’ one of the cylinders, causing a loss of power from the gasoline engine and the hybrid system attempted to compensate for lost power, resulting in engine failure” later that day when I arrived from work to get a loaner I was told that it was a broken camshaft and warranty would pay for a new engine.”

On three separate occasions the vehicle refused to accelerate after being in a stop and go mode (I.e. traffic/drive thru). All three times an alert popped up on the dashboard stating: HEV Check Hybrid System Stop Safely. The second time this occurred a diagnostic code came up: DTCP112000. In all three occasions turning the car off and restarting resolved the issue at least temporarily. Also- the battery was completely depleted after each incident. Vehicle is at the dealership service center for the second time without and current diagnosis or solution.

My vehicle that I finance is a 2022 Hybrid Tucson it failed at 14,596 miles I had it since November 2021 so for a good 9 months until it decided to finally malfunction. As I been driving it previously for the past month I’ve been hearing the transmission struggle a lot more everyday that I use it. I also noticed that the engine really lacks power, when I accelerate it takes a really long time for the gears to shift which has been getting worse for the past month now. Which is what I believe led up to my vehicle losing complete engine power while I was driving 30mph. I saw on my digital cluster a message saying “Check Hybrid System, Stop the car safely.” In an orange triangle, I had cars backed up close to me and I was confused as to why this was happening to my not even a year old vehicle. This is a major safety issue to me that while I’m driving anywhere my engine will go completely off and I am only to rely on 20mph on EV Mode. If I was on the freeway I could’ve gotten into an accident and with my whole family in the car. I personally feel unsafe driving, it’s my daily driver and my only way to get to work.
