1 Automatic Transmission Control Module problem

Failure Date: 01/11/2025

I received a service hybrid electric vehicle system warning. Also vehicle speed may be limited warning. When I shut the vehicle off, it was loud and remained running. My safety and the safety of others were put at risk because the warning happened while I was driving and I couldn’t get speed to park in a safe location. I had my car towed to a local Chrysler Jeep Dodge dealer and they updated software related to my car that was the source of the problem. They also told me the battery completely drained. The recall was due to a faulty pcm that the recall was for. You can see in the invoice the problem I communicated to the manufacturer before they diagnosed my vehicle. You can see clearly the vehicle was still active even after shutting off, likely causing the battery to drain completely. And due to the faulty pcm, it failed to tell the systems to shut down. Chrysler is giving me $100 for the tow. But they say the battery is out if basic warranty so will not reimburse me the $650 or so for the battery. My argument is that it doesn’t matter if the battery is out if basic warranty as the draining of it was a direct result of the recall and failed pcm. There is case law that supports the fact that if a recall-related defect (such as a faulty pcm) directly causes a secondary failure (e. G. , battery damage), the manufacturer still bears responsibility, as the defect rendered the vehicle unfit for normal use.
