2022 HYUNDAI TUCSON Complaints

The trailer towing guidance in the 2022 Hyundai Tucson Hybrid owner’s manual is incorrect and would put the driver in a dangerous situation if followed. There are at least two key errors: - Page 6-68 states, “The trailer tongue should weigh a maximum of 10% of the total loaded trailer weight . . .” This is incorrect. For stability, the trailer tongue weight should be a minimum of 10% of the total loaded trailer weight. - The table on page 6-69 lists the maximum trailer weight when equipped with a braking system as 3,500 pounds. However, the table also gives that the maximum tongue weight as 220 pounds. That equates to a 6.3% tongue weight. I contacted Hyundai to ask for clarification (see attached email). They told me that “Towing capacity is based on engine power and other such concerns. Tongue weight is determined by the material strength of the hitch, anchor points, etc. and therefore the two will not necessarily coincide.” I then asked them what the tongue weight limitation was based on and they said they did not know. The owner’s manual is over 11 Mb, so I have only to two pages of concern.

While driving on the freeway, suddenly lost power while driving 60 mph and was unable to accelerate. Almost avoided an accident, while trying to merge to the shoulder of the road, while the car just puttering. While on the shoulder, the check engine light came on. Unable to drive and had to get towed.

The contact owns a 2022 Hyundai Tucson. The contact stated that the tailgate independently opened while driving. The tailgate warning light was illuminated. Additionally, the wheel well molding had detached. The vehicle was repaired at an auto body shop. Additionally, the contact stated that there was water intrusion into the headlight housings, and there was a sharp plastic part coming through the rear seats. The vehicle was taken to the dealer and was repaired. The contact stated while driving above 65 MPH, the vehicle was vibrating and would make an abnormal echoing vibrating sound. There was no warning light illuminated. The vehicle was taken to the dealer, where the tires were replaced; however, the failure persisted. The vehicle was taken to the dealer several times. The dealer informed the contact that they could not duplicate the failure. The vehicle was taken to a second dealer, where it was test driven; however, the dealer could not duplicate the failure. Additionally, the contact stated that the brake pedal was pulsating while depressed. The vehicle was taken to dealer, where the brake rotors size was reduced; however, the failure persisted. The dealer advised the contact to take the vehicle to their location for the same repair to be completed. The vehicle was not diagnosed nor repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 3.

On at least six occasions since I took possession of this Hyundai vehicle the vehicle has been automatically slowed down accompanied by a "25 mph speed limit" sensor light coming on - and most of these instances could be dangerous because they were not in low-speed zones. This has happened in low-speed zones or near those, in particular on/near a college campus that I drive through or near, but several times this happened when I was in a 35, 45, or 55 mph zone. In fact, yesterday around 6 p.m., after starting the car a minute earlier I pulled out of a driveway onto a rural highway (55 mph) and the car slowed immediately and that warning came on and it did not go off until I shut the car off about 5 minutes later. This was nowhere near a low-speed zone, it was several miles from one. When this has happened in higher speed zones the only thing that makes sense sometimes is to try and "override" the setting by putting the accelerator to the floor, but that isn't ideal as I have discovered, because while it will eventually override the sensor it also causes the car to rocket once it does. Besides that, the car can be shut down and that seems to reset the sensor as well, but sometimes you can't just pull over and restart.

The contact owns a 2022 Hyundai Tucson. The contact stated that while driving at various speeds, the “Forward Collision Avoidance” feature limited and Radar Blocked messages were displayed. On two separate occasions, the vehicle independently decelerated while depressing the accelerator pedal to override the defect. The vehicle was taken back to the dealer however, the mechanic could not duplicate the failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 10,000.

Sudden loss of power and speed on freeway traveling at 75 mph almost caused a rear end collision by tailgating semi. Pulled over onto shoulder with engine shaking and bucking and luckily limped off nearby exit. Engine control system error popped up. Engine would barely start and stall quickly and eventually would not restart at all. This is the cars second sudden power loss and engine problem at speed since. Not acceptable for a brand new car.

The car slowed down so I tried stepping on the gas pedal and noticed it wasn’t working, then I tried stepping on the brake pedal and it didn’t work neither. The car slowed down and called it to get towed.

Driving on highway long distance on sunny days the radar becomes blocked disabling critical forward safety functions and cruise control. Numerous times this has caused a near collision due to the automobile malfunctioning. Many times my cruise control has just stopped working and my vehicle has rapidly decreasing speed, causing people behind me to have to slam on their brakes. My vehicle has also automatically braked on the highway when there was no one in front of me. these are just two incidences that have nearly resulted in collisions on the highway. This has been occurring since I purchased the vehicle in September 2022. Unfortunately, dealership has not been able to duplicate what has occurred.

First occurrence was on 6JAN23 when the vehicle was being driven and it suddenly and quickly reduced speed to under 30mph. Vehicle then continued to go up in RPMS to nearly 4,000 but the car felt like the transmission was not engaged and driving in neutral then would engage and disengage, causing fluctuations in speed, but never above 30-35 mph. This continued to happen until we could pull over safely and turn off the vehicle and restart. No engine light or warnings illuminated. Vehicle was taken to the dealer for diagnostic and nothing was found. Second occurrence was 01ARP23, with exactly the same results. In doing some research I have found several other complaints with this issue. This is a serious accident waiting to happen.

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.
