“The contact owns a 2015 Ram ProMaster 2500. The contact stated that the same day that the vehicle was purchased, the check engine warning light illuminated. The contact stated that after shifting to park(P) and the parking brake was engaged, the vehicle rolled backwards. The vehicle was taken to the dealer, who diagnosed the vehicle with an unknown sensor failure. The sensor and the brakes were repaired. The contact retrieved the vehicle, and the check engine warning light was illuminated. When the gear lever was shifted to park(P) and the parking brake was engaged, the vehicle rolled backwards. The dealer was contacted, and the dealer at first refused to take the vehicle. After several months, the dealer took the vehicle, and it was diagnosed and determined that the fuel injectors, brakes, fuel tank, and an unknown sensor needed to be replaced. The vehicle was not repaired due to the cost. The contact stated that the failure persisted. The vehicle was parked at the residence and had not been driven since. The manufacturer was not notified of the failure. The failure mileage was approximately 60,000.”

“exited a freeway, and when taking off at the stop vehicle lunged forward into the intersection and went out of gear. after repeated attempts to accelerate, drove about 200 feet and dropped out of gear again. Had vehicle towed to Dealer who said needed a new transmission and a left engine and transmission mount because the mounts are breaking causing the engine and transmission to drop nearly to the pavement. An article posted June 2019 by certtrans details the failure (search online for: mopar fix for ram promaster transmission bracket breakage). There are many possible catastrophic safety issue from this failure. Why have these vehicles not been recalled for these defective mounts? The upgraded mount was an additional $847. The price alone may scare some people off from replacing with upgraded mount. At highway speeds when the engine and transmission fall down the angle of the drive axles alone could cause breakage and loss of power. Plus there are a many other possibilities for this to cause a crash.”

“Several incidents when accelerating, the engine goes into a limp mode, followed by indicator lights coming on P0401, P0299, P226C. The vehicle will not accelerate and travels at a max speed of about 5mph. This has happened in traffic every time and has put me and my family, as well as other vehicles, at extreme risk of being in an accident, not being able to accelerate out of the way of oncoming traffic. After several cycles of turning the vehicle off and on, it returns to normal function. The vehicle has been inspected at a Dodge Service station. They determined that the Turbo diesel system is malfunctioning and needs repair. My vehicle is available for inspection upon request.”
