My truck would not start. I found that I could shift the vehicle into gear without the key in the ignition or foot on the brake. It appeared that the truck would not start because it could not tell when it was in park. I had to be towed to a dealership, who discovered that the Shift Interlock Solenoid had failed. There is a previous recall for the same year, make and model of my truck, but did not include my VIN. I feel that this is the same issue for which the recall was issued and mine should be included. I incurred a $640 repair bill.

I received notice of a safety recall concerning the brake/ anti-skid control module. This notice said there was a possibility of complete failure that could result in serious injury or death. I contacted my local dealer and was told the recall wouldn't start until the first quarter of 2025. I told them my dash warning lights were already on. Their advice was to park my vehicle and obtain other transportation because of the danger. This seems to be unreasonable to me. It would cost a lot to rent another truck for that period of time. This seems to be putting my family and me in danger! Is there anyway to proceed earlier?

The abs light and traction control light came on with chiming going off. The lights would go on and off at random. Didn't start till I washed my truck. Took to dealer they said the ABS module bad and ordered it. They say warranty will cover it. They shut the light off and reset the system. Stayed off till I washed the truck again. The part is in just need to have taken to shop to put on. This should be a RECALL for as many of these trucks that this has happened too. The cruise control, won't work and how do you now that the brakes will stop the truck if someone pulls out and you hit the brakes hard if the ABS system isn't working right. They inspect the truck and see that the ABS system was not working who is liable in a law suite. Chrysler won't say that it is a problem. Something needs to be done about Chrysler (or any manufacture) responsible for the safety of the consumer buy there product. The truck only has 21,536 miles on it now. If it wasn't under warranty it wouldn't be fixed. It had 20,659 miles when went in to dealer. it had 20,583 miles when the light first came on.
