Adaptive cruise and forward collision warning failed regularly for 10 months. Dealers worked to find issue after having car in shop for collectively about 3 months. Dealer replaced parts, and finally determined it was a 4g adapter sold by uconnect- a part of Dodge parent corp. Mopar tech's were aware of it, yet to my knowledge they still sell the 4g service. Use of the adapter with remote start disables fcw and acc. I have pictures and documentation. They should stop selling this or fix software.
2015 Challenger, wheel speed sensor failures starting at year two. Have replaced wheel speed sensors on 5 separate occasions. It has affected all wheel speed sensors and fron passenger replaced twice. All replacement parts are from dealer and are geniuine mopar replacements. Seems to be a very common issue, the parts are typically on backorder and it can be caused simply by going through a car wash.
