2023 Hyundai Tucson Hybrid Driver assistance Problems

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. Had we been on the interstate we would have died, These incidents were sporadic and occurred on and off during the month of April and May. Each of the above occurred numerous times to different drivers. Service at two locations were unable to ID. We sold the moving death trap to one of the Hyundai dealers who could find no mechanical problems with the vehicle. The vehicle was terrifying to drive. There are other reports on this vehicle of these issues ... which appear to be electronic. Hyundai has good engineers. They know what is causing this and simply do not want to replace a very expensive but obviously failing electronic control module.

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. We did talk to police shortly after the accident but we are unsure if they filed a report.

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. One dealership has evaluated the vehicle twice and a second dealership once but we have been informed that there was no defect identified. I believe this issue to be a serious safety defect.

The ABS, ! Brake and Auto Hold lights activated. I took in into the Hyundai Joplin, MO dealership on May 2, 2024. They could not find any thrown codes and suggested it was most likely the "IEB Module" which they replaced and after doing so, the warning lights remained activated. As of May 22, 2024, they are ordering a new IEB Module to install (backordered into June). This seems oddly similar to previous ABS and brake problems of earlier models and makes me feel uneasy with the safety of this vehicle should they ever get it remedied.

I was driving on the freeway and suddenly the auto emergency breaking auto system activated. However there were no cars ahead of me, the road was completely clear. I was driving within the speed limit. Thankfully there were no cars behind me; otherwise this could've ended very badly. I pressed on the accelerator multiple times and the emergency breaking disengaged. Since I was driving I did not want to get distracted by figuring out how to disable auto assist. But the next time I got into my car I am went into the dashboard system to turn off auto emergency braking and set it only to provide warning notifications. it was not that easy to do. I had to Google it and look at multiple user forums to figure out how to turn off auto emergency breaking in the dashboard.

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. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 3,000.

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. Cruise control is off, and no other speed limiting system is activated. There are no warning lights or indicators when this occurs. This is incredibly dangerous, as I am unable to get up to speed on a main road. A few instances led me to be unable to successfully merge onto a main road, which has led to me almost being rear-ended on one occasion, and the most recent instance I was in the left lane of a main road and attempting to pass a large truck and could not maintain speed. I was fortunate to come upon a slight downhill slope and was able to coast across the right lane and get off the road, but it was a near-accident. The dealer service center was unable to diagnose the issue, and therefore could not repair it.

My son was backing out of a parking spot at a strip mall. He released some pressure on the brake and indicated that the car lurched backwards and even though he reapplied full pressure to the brakes, he hit the car at the curb resulting in damage to our Tucson, but luckily not the to the other car. The Rear Cross-Traffic Collision-Avoidance Assist system did not engage, but my son indicated that the rear distance warning system did beep. I am concerned due to the sudden acceleration/lurching incident my son experienced and this is not acceptable in any car. I ask the NHTSA to see if other Hyundai Tucson or Kia Sportage owners, especially with the Hybrid engine are experiencing this.
