2022 Volvo XC40 Speed Control & Cruise Problems

The contact owns a 2022 Volvo XC40. The contact stated the vehicle was in park, with no accelerator pedal or brake pedal being depressed when it experienced an unintended acceleration. As a result, the vehicle crashed into a pole where it came to a stop. The air bags did not deploy. A police report was not filed. No warning lights were illuminated on the vehicle. The contact mentioned the auto braking did not engage along with the other equipped safety features. The vehicle was restarted and driven to the owner's residence where it remains. The vehicle was not diagnosed or repaired. The local dealer and manufacturer were notified of the failure, and a case was opened with the manufacturer. The failure mileage was 33,710.

When backing the vehicle out of a parking space on Wednesday, December 21, 2022, the vehicle lurched and moved very slowly. The center HUD displayed the message, "Slow Down. The Vehicle will reduce speed. Propulsion system failure." The vehicle was towed to the Volvo certified dealer in Roanoke VA. The technician "reset" the error code and released the vehicle to me. The dealership could not tell me if the vehicle was safe to drive. I called the dealership multiple times, and they stated the problem was being investigated by Volvo corporate. Still, no one can tell me if and the conditions the vehicle will begin its automatic deceleration protocol. I have a second report now from the dealership that the error must occur twice for them to investigate it more thoroughly. I feel fortunate that this occurred in a parking lot, and not while travelling at any speed in heavy traffic. Volvo online forums have been reporting this error since at least August 2022. https://www.xc40forum.com/threads/propulsion-system-failure.5150/ This is the second response from the dealership after I called today for progress: "–based on your DTC codes it appears you are referencing TJ-36309, CMA BEV IHFA Internal Processor Failure. At this time the concern has only occurred 1 time and has not returned after following the TJ. A software fix is still under development to prevent misdetection of these DTCs, as you stated. This TJ was only released last month, VCUSA is working towards a solution. However, if the codes return it signals further fault tracing is needed and we will have to evaluate the situation if it happens." This does not sound safe, and I thank you all for reading.

The contact received medical assistance the following day. A police report was filed. The vehicle was towed to a tow lot. The manufacturer was notified of the failure and referred the contact to a Volvo Collision Center.
