2023 Hyundai Tucson Hybrid Vehicle speed control Problems

“Our 2023 Hyundai Tucson Hybrid developed an issue with the forward radar. At speed, the car produces a warning ding and then a warning message is displayed stating, Critical Forward Safety functions are limited. Radar blocked. If the adaptive cruise control is engaged at the time of the warning, it immediately disengages, forcing the driver to quickly respond. If there is a vehicle in the adjacent lane to the right, the automatic braking may at times activate. It happens rain or shine, in good or inclement weather. We have cleaned the areas of the sensors without effect. …”

“On four occasions in the last five weeks, I have been driving at relatively low speed (20-30 MPH), and when I attempt to accelerate, the vehicle will not accelerate when I press the gas pedal. The tachometer shows the RPMs are maxed out, but the vehicle does not accelerate no matter how hard I press the gas pedal. I have to pull off the road, turn off the vehicle, and restart to fix it. I am certain I have not accidentally hit any buttons or switches each time. I have tried changing drive modes (eco/normal/sport) and using the paddle shifters and that has no effect. …”

“As I was (very slowly) pulling into a parking place at a park near my home and I was braking to come to a full stop, the car suddenly lurched forward, jumped the parking place barrier, and hit a tree. The front end of the car was badly damaged and the airbag opened. I sustained injuries to my left hand and my chest, though nothing was broken. The car was towed to a body shop, where it has been declared not reparable. Photos of the car at the scene are attached. This accident seems to be consistent with reports/recalls of the Hyundai Elantra of unintended acceleration when releasing the brake. …”

“The contact owns a 2023 Hyundai Tucson. The contact stated that while driving at slow speeds and attempting to park the vehicle, the vehicle unintendedly accelerated before the contact was able to regain control of the vehicle. The following day while driving away from a stop light, the vehicle briefly shuddered and was unable to exceed 20 MPH, prompting the contact to pull to the shoulder of the roadway. After restarting the vehicle, the vehicle returned to normal functionality. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to duplicate the failure. …”

“1. Sometimes vehicle does not start. Only starts if battery reset button pushed. 2. Sometimes vehicle while moving has delayed braking after juddering. Only stops when car stopped and restarted. 3. Sometimes vehicle while moving suddenly revs, RPMs spike until car stopped and restarted. Engine revs but does not shoot forward. 4. Spookiest of all, while moving car suddenly stops accelerating. Pedal on the floor and it is coasting to a stop. When car stopped, and turned off, then it will work. …”
