On August 1st I was on the highway at 55 mph when my 2022 Hyundai Tucson decelerated to 20 mph and would not go faster. This occurred on the highway at 5:45 pm. This placed myself and others in danger as I was on the highway in the center lane at the time of the deceleration. After turning the car in, the dealership returned the car with no repairs but stating that I engaged a button that caused a limit to the car's speed. I didn't understand but took their word. I drove it from the dealership to the store and home. The very next morning while taking my grandson to school at 5:15 am the car decelerated from 45 to 20 mph with my grandson inside the car. This placed myself and a family member in danger along with cars around me. Each time I had to drive to the dealership in unsafe conditions. They stated that I was not engaging the brake enough to charge the battery. I do not know of ANY documentation stating the number of times the brake must be engaged per drive. I have never heard of such engineering that allows a car to only go 20 mph and create a hazard for the occupants unknowingly. The dealership has stated that refuse to fix the problem but I should engage the brakes more often when I drive. The car has spent several months in their care due to continued repairs over the time that I've had it and is currently their because of the engine light being on.

Car lunched from a traveling in traffic 50+ mph to 39 mph and then had to push the pedal to the floor to get it off the highway and on the side during 5 o'clock traffic. Said something about the hybrid battery and went dead. Dealer has had it for 11 days and still can't get it started. Apparently there are THREE batteries in relation to this hybrid and all 3 don't work and never seen this before. Since it's been at the dealer, hyundai has emailed me no less than 3 times that I need to check my lights because my battery is getting low all the while it has been completely dead and they don't even know it. Suffice to say, there was NO WARNING other than a couple of miles prior, my car lunched down to the 39 mph and I lunged on the gas and it picked back up again but it wouldn't do it a 2d time. They obviously still don't know about the vehicle being so dead 2 different tow trucks had to be called because even the tires were locked up. Just still receiving my messages I need to check my lights because my battery (NOT BATTERIES MULTIPLE) is low and it's not low, THEYRE ALL 3 DEAD. I was in a dangerous situation and always felt safe in a 2 yr old car with a full tank and hybrid battery backup and less than. 20k miles. IF EVER FIXED because service may have to send OUT OF STATE I will never buy a hyandai or hybrid again. The entire battery system broke down. Which killed the entire electrical system which now no one knows how to fix

While driving on busy highway the vehicle would not accelerate even with more gas applied. Gave warning to check hybrid system and pull to safety. Vehicle wouldn’t turn off after pulling over and in park with flashers on. Various warning lights all came on, gave message of battery discharge warning, check brakes, check ABS, check brakes then everything complete shut off including hazard lights. Wouldn’t start after that until jumped by tow driver. This is the second time this occurred, first time being within the first year after purchase.

I have noticed this only happens on very cold days and it has Happened 7 times now. The car will be driving along and suddenly lose all power to the point you cannot accelerate above 15 MPH even if you floor the gas pedal. While this happens the Battery indicator will drop to 0 and then a Message Check Hybrid System pops up. Once the car comes to a complete stop the parking brake will automatically engage and will not release. If you shut the car off and turn it back on, A message please wait while battery charges is on the display and will not disengage the parking brake until the battery charges up to about 35-40% . The dealer has looked at the car 4 times and found nothing as no codes ever registered. I even opened a case direct with Hyundai Consumer affairs and they can not seem to find anything wrong with the car nor do they think it is an Issue. I find this to be extremely unsafe for a vehicle to randomly lose power and refuse to come out of park regardless of where on the road you happen to be when this occurs. It has not happened since the temperatures have been above freezing, but with winter a few months away. I completely fear for my safety.

I turned right into my driveway at a slow speed. As I went onto the driveway, the car surged forward. To avoid driving into the garage door, I turned to the left to drive along the side of my house thinking I would be able to stop it. I kept hitting the break but the car kept going. When the vehicle did not stop, I steered to the right because I thought it could be possible that my neighbor's dog could be in the adjacent yard (to the left of my house) The ground between the houses is pitched down (to the left) towards my house and I side-swiped the back half of the side of my house. Although applying the break, my car continued after sideswiping the side of my house with the front right side of my car and went into the house behind my house causing damage to that house. My car stopped when it went into the house behind my house.

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

My vehicle takes over my breaks and completely takes control of my vehicle away from me (the driver). It does this randomly. I had a hit and run in a parking lot due to this issue. I am greatly concerned for my safety.

Attempting to enter I-295 South in Portland, ME at Exit 7 on March 18, 2023. We were in our 2022 Hyundai Tucson Hybrid Limited with approximately 6,000 miles. I tried to accelerate from the ramp to merge into traffic. The vehicle would not accelerate at all. I made several attempts to accelerate and nothing would happen. Pulled into the breakdown lane while applying pressure to the accelerator but it would not accelerate. The vehicle was in EV (electric vehicle) mode. After approximately 1 minute the vehicle did accelerate. No further problems that day. We called the dealership immediately and left a message regarding the incident. On Monday March 20th We followed up with the dealership and scheduled an appointment for the next day On the 21st of March We dropped the vehicle at the dealership. We picked it up at the end of the day and they told us they installed a software update TSB 23-EE-002H to repair the issue.
