Consumer Description

Valve lifter failure at 93,000 miles. $2,700 repair. Is apparently a very common problem with the 3.6l Pentastar engine. Adaptive Cruise Control and Forward Collision warning system front sensor failed at 56,000 miles, failed again at 76,000 miles and failed a third time at 95,000 miles. First two failures were replaced under warranty, third failure happened 1 week after warranty expiration from second replacement. Cost is too expensive to repair ($3,000 for new sensor) and requires that safety feature be turned off as sensor will perceive increases in road elevation (hills) as another vehicle and apply the brakes
