There are 7 owner-reported powertrain & transmission complaints for the 2021 Ram ProMasterin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
On [XXX], while driving my 2021 Ram ProMaster 2500 at highway speed in Florida, the van suddenly lost all power and came to a near stop, then re-engaged. Vehicles were in front and behind me, creating an immediate risk of serious collision, injury, or death. I pulled over ~30 minutes, restarted, but it could not exceed 20 mph while RPMs were high. AutoZone confirmed limp mode and advised a dealer. I drove it home to Port Charlotte, then had it towed to Gettel Dodge Chrysler Jeep Ram, Punta Gorda, FL, where after two weeks it was diagnosed with a failed transmission requiring replacement. The transmission can be inspected at the dealership. No warning lamps appeared before failure. Problem confirmed by AutoZone and the dealer. I contacted Stellantis (Case #[XXXX], contact Regina Knox; dealership contact Noel), but repair assistance was denied. The van also has two active recalls, including risk of rolling out of park, unremedied. This transmission failure constitutes a serious and imminent safety defect, creating a hazard to myself and the public. I request NHTSA investigate this defect, compel Stellantis to repair it at their cost, and consider any further regulatory action necessary to prevent injury or death. Vehicle info: 2021 Ram ProMaster 2500, 130,000 miles, VIN [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
I purchased the vehicle above used on 4/22/2024 with roughly 70,000 miles on it. At 121,000 miles I lost the reverse gear in the transmission and the vehicle displayed 2 code P0736 and P0792. I call my local Chrysler dealership and inform him of the situation, and the service manage advise me of a recall 44A / NHTSA 23V-301 and asks for the VIN. He tells me that the recall has been completed on the vehicle and the cost to fix (replace the transmission) the vehicle will cost me about $4,000.00. I read the recall notice, and it states the vehicle effected had roughly 133,000 miles. The recall must have been closed by the previous owner but that does not change the fact that the manufactures initial repair did not cure the problem being that my vehicle had the catastrophic failure close to when the manufacture stated the problem in the recall. There are many owners of the same vehicle out there that will attest to the transmission failure on these vehicles. I would hope your department will take a serious look into this matter and hold the manufacture accountable and reimburse the cost of the repairs to the owners.
Ram Promaster van continued to roll (backward) when securely shifted into park
The driver was driving uphill when his RAM ProMaster suddenly lost power and rolled back down the hill, hitting a tree and stopping. During this time, the driver had absolutely no control over the vehicle, and the brakes didn’t work at all. The driver attempted to steer the vehicle, pumped the brakes, turned the key, and pulled the emergency brake, but nothing worked. Internal and external cameras captured the entire event. Will provide video upon request, cannot upload.
The Transmission in these vehicles have been known to fail. This is just one of 38 in our fleet. Currently there are 8 of these vehicles at dealerships with transmission problem. We also have 4 more now that have to wait for dealerships to have room for them. Between the 2 dealerships within 6 miles of our business headquarters, they currently have almost 70 ProMasters with transmission problems and can only fix one at a time due to lack of parts. Some wont shift out of first, some wont shift into drive at all, and only work in reverse. The danger comes from not being able to shift while on busy roadways. leaving drivers stranded sometimes many miles from our fleet people that can help them get back to headquarters. If this is not the proper agency to report this to, then may we kindly request being pointed in the proper direction
