2023 Hyundai Tucson Hybrid

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.

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.
