This is in regards to cooling fan overheating and causing fire. My closest dealer scheduled me for the recall knowing why I was coming in. When I arrived they told me it was a lengthy repair but confirmed it would be done by the end of day. I changed my plans around this and when end of day came they said the did not have the parts on hand to complete the recall and needed to order them but confirmed the vehicle indeed needed the recall parts. why would they schedule the service, check on the timeline, and then figure out they didn't have the parts? I was down a work truck, work day, transport cost to and from dealer, added an oil change because I would be there only to be let down like this. I have heard nothing from the dealer as a follow up on getting this resolved

Dec 23, 2025SteeringTransmission & drivetrainElectrical system

The vehicle suddenly and without warning experienced a complete loss of steering control, rendering it undrivable and forcing it to stop on the side of a public roadway. This created a significant risk to my personal safety and to public safety. On the same day, the vehicle was towed to an authorized RAM dealership for inspection. The dealership confirmed that the serpentine belt had broken, there was abnormal noise from the alternator, and the entire power steering system was internally contaminated with metal shavings, requiring complete replacement of the power steering system. The selling dealer has refused to accept rescission of the sale and has also refused to cover the necessary repair costs. The vehicle was unlawfully sold to me while it was subject to an unresolved safety recall, demonstrating a serious disregard for my safety and the safety of others.

Helo, The rearview camera on my commercial cargo vehicle is defective. I've been waiting for it to be replaced for two months, but they haven't responded. Reversing maneuvers are very difficult and risky in a large vehicle. I'm asking for your help.

Feb 6, 2025Tires

Tire size LT225/75R16. Tires are OEM on 2021 Ram Promaster 3500 - Purchased New in February 2022. Vehicle has 24,500 miles and tires are regularly rotated. Presure check of tires showed tires were at proper inflation for vehicle. TPMS did not issue a warning, because tire never lost pressure. On February 6, 2024 when driving southbound by mile marker 250 on Interstate 75 in Florida, the steering wheel started feeling funny like I was driving on a really rough road. When I looked out my rear camera, it appeared that tire tread scraps were coming from my vehicle. After slowing down to the breakdown lane, I inspected all four tires and found that tread had separated from the middle of the drivers side rear tire. I was able to slowly make my way to a nearby rest area, when I got help changing the tire out to the spare. The tread separated and caused the van to be unstable. The flying tread pieces were a danger to other vehicles on the road. If I had continued driving, the tire could have exploded causing damage to my van and to other vehicles on the road. Called dealer and was told these tires only have a 90 warranty.

Nov 15, 2024Brakes

My van began making a loud squeaky sound, louder at low speeds and less at higher speeds. It sounded like it was coming from the wheels or undercarriage. There were no dash warning lights, alarms, or any other indicator of a serious issue. I drove the van around town for a few days approximately 30 miles. The van is heavy and I live in a hilly area, so I use the parking brake fairly often. I applied the parking brake within that week on an incline, and when I released the parking brake and drove forward, the squeak was louder then ever, so much so, people stared. There were no error or warning message on the dash or elsewhere. The parking brake indicator had come on normally while engaged and went off when it was released. I drove it directly to the local Ram dealer, as it seemed worse, hoping it was just in need of minor lubrication. It had just been serviced at the same dealer a few months earlier and I was told "it was like new with its low 12,500 miles". I explained the new noise and that I didn't want to cause damage by driving it, although there were no warning lights on. My van is still under the original warranty for a few more months. Even though they were booked, an employee went out and felt by the rear driver's side wheel and said it was really hot and likely a frozen brake caliper. They were able to fit me in and discovered the parking brake was frozen, which was causing the noise. They ordered the parts to repair, disengaged the parking brake, and said it was safe to drive as the main brakes were a separate system. They said not to apply the parking brake again as it would hang up as before. -The dealer ordered the parts over a month ago, but said the brake parts are not only on back order, but with no estimated shipping date, meaning they aren't even manufacturing them. -I am driving without a parking brake in a heavy vehicle in a hilly area with no pending solution and heading into winter weather. This is a safety issue! Please help ASAP.

While preparing for a trip, I noticed the upper kitchen cabinetry is detaching from the ceiling and in danger of falling. This section is part of the cabinetry housing the microwave. The detaching cabinet has a glass plate attached to the bottom as a heat guard for the stove directly below it. The stove also has a glass top. It has the potential to injury an occupant both by its weight and glass breakage during travel or when stationary. Occupants can be sitting directly across from the cabinet on the couch which has seat belts. There is a 16 inch aisle between the stove top and the edge of the couch. I'm not sure if this is the appropriate type of safety issue for your agency, but I felt it could surely injure occupants in the kitchen area.

The component that failed/malfunctioned is the CV axle, the part is no longer available for inspection. The safety risk posed is loss of control of the vehicle, subsequent damage to other vital steering and stability parts such as the wheel bearings, axles, alignment, and lower ball joint. The problem has been confirmed by a RAM dealership, and corrected under an extended warranty. The component has not been inspected outside of the RAM dealership technicians and potentially the warranty provider. There were no warning lights or indicators from the computer/OBD. Physical symptoms and signs included uncontrollable vehicle shaking/vibration, and difficulty maintaining control at high speeds. Other symptoms/signs may include the frequent need for realignment, and unique tire tread wear patterns. Symptoms appeared around 58,000 original miles. With a fleet of these vans, this problem has been noted more than once.

This unit will not go up hills. The RPM are 5-6 and the speed is only 40mph Semi trucks pass us going up hills We cannot drive speeds beyond 55-60 mph with highway driving This causes a danger to ourselves and the drivers around us. The backup of traffic is not safe. The dodge ram dealership advised us the unit is not road ready for hills because of its weigh. Can you access the safety of this unit

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Ram Promaster (passenger Double Seat) verdict →
