Ram Promaster overheating problems

Filed Sep 4, 2026 · Engine · CA

I am submitting a safety complaint regarding my 2022 Ram 3500/Thor Class B RV, VIN [XXX], with only approximately 6,858 miles, which I brought to a dealer in the Inland Empire for Recall [XXX]. Before taking my truck to the dealer, there was no known coolant leak. The vehicle was in good condition and operating normally. I left the truck with the dealer specifically for the recall service. After approximately two days, the dealer called me and said they had found a coolant-system leak and that I would need to pay approximately $1,500 for repairs. I was surprised because there was no known leak when I delivered the vehicle. I immediately contacted MOPAR for assistance and asked whether the leak could be related to the recall service or whether the repair should be covered. Unfortunately, MOPAR did not resolve my concern. I declined the $1,500 repair. The dealer told me they could not guarantee there would be no leaks after the recall repair was completed. When I picked up my truck, the dealer did not tell me that the coolant leak was still present or warn me about driving the vehicle. I drove the truck home. After getting home, I opened the hood and discovered a long screwdriver left inside the engine compartment. I am not claiming that the dealer caused the coolant leak. However, I am concerned about the timing of the leak, the recall service, the $1,500 repair demand, the lack of warning at pickup, and the screwdriver left in the engine compartment. I respectfully request that the federal safety agency investigate whether this coolant leak may be related to Recall 67C, the recall repair, an improper repair, or another safety defect. NOTE: I am now seeing on your website that it appears the Recall 67C repair has not been recorded as completed for my vehicle. I have uploaded a screenshot of the information shown on the website for your reference. Please review this discrepancy as part of my complaint.

Related recall: the federal safety agency 25V720000 / Chrysler 67C — "The electrical circuit for the radiator fan may overheat." Fire/injury: No fire / no injuries; component overheated and burned/melted. Complaint narrative (paste this into the form) The radiator cooling fan on my 2020 Ram ProMaster 3500 (3.6L gasoline V6) repeatedly became stuck running / would not shut off on multiple occasions. The cooling fan electrical circuit overheated, and the fuse and fuse box (power distribution center) burned and melted, which in turn damaged the adjacent wiring harness. The fuse did not protect the circuit before the overheating and thermal damage occurred. This is the identical failure mode described in the federal safety agency recall campaign 25V720000 (Chrysler recall 67C), which states that "the electrical circuit for the radiator fan may overheat" and that "electrical circuits that overheat increase the risk of a fire," with a remedy of replacing the cooling fan module and fuse. My vehicle is a 2020 ProMaster, within the 2018–2026 model years covered by that recall. However, when I contacted Ram/Chrysler, I was told my VIN is not included in the recall population. I am filing this complaint because my vehicle experienced the exact defect the recall was issued to address — a stuck-on radiator cooling fan causing the fan electrical circuit to overheat and burn the fuse box and wiring harness, creating a fire risk. I had to pay to repair this damage. I request that the federal safety agency review whether the recall population should be expanded to include my VIN and other affected vehicles exhibiting this same failure. Documentation available on request: photographs of the burned/melted fuse box and damaged wiring harness, and repair invoices showing replacement of the cooling fan/fan module, fuse box, and wiring.

The specific issue you are dealing with is Chrysler Recall 67C (the federal safety agency Campaign 25V720). This recall impacts nearly 300,000 Ram ProMaster vans (model years 2018–2026) due to an overheating radiator cooling fan circuit that poses a significant vehicle fire risk. More than 200 of these are from the VA. Edwards Auto Group In Council Bluffs, IA is trying to make the Veterans Health Administration pay labor for a safety recall that is stated above. I am reporting them because it is a safety recall and we should not have to pay for extra cost such as a 2x4. Please see below. It is my understanding that the Dealer is in the wrong here. •Absolute Free Labor: Dealerships enter franchise contracts with the manufacturer requiring them to execute recall repairs for free. Chrysler (FCA US LLC) is legally obligated to provide the instructions and billable labor hours to the dealership. •The "2x4" Tool Excuse: If a manufacturer's official technical service bulletin specifies a specific physical manipulation or tool—even a makeshift one like a 2x4—to complete the repair, that labor time is factored into the flat-rate time Chrysler pays the dealer. The dealer cannot pass "difficult labor" or tool costs onto you. •No Deductibles or Add-ons: A dealer cannot apply any separate fees or surcharges to offset their operational challenges while resolving a safety defect.

While operating a 2023 Ram ProMaster 2500 (3.6L V6) for normal commercial use at approximately 39,129 miles, the coolant began bubbling and engine temperature spiked suddenly while driving. The vehicle was immediately parked and towed to an authorized Chrysler Jeep Dodge Ram dealership as it was completely undrivable. This created a serious safety risk as the vehicle lost drivability suddenly on public roads during active commercial operation. Upon teardown the authorized dealer documented: coolant leaking into cylinders 3 and 4, coolant coming out of exhaust, stretched engine bolts, warped block and head, and internal coolant leak causing overheat. No external leaks from the cooling system were found. The internal component failures caused the overheating not the reverse. The vehicle was still within its active powertrain warranty at time of failure. Stellantis denied the warranty claim under TSB D-23-20 claiming an undetermined overheat caused the engine failure directly contradicting their own dealer's findings which show zero external cause. I have paid $9,000 out of pocket for repairs that should be covered under active powertrain warranty on a 3-year-old vehicle under 40,000 miles. I am requesting the federal safety agency investigate this failure pattern in the 3.6L V6 Ram ProMaster 2500 as other commercial operators may face the same sudden dangerous failure.

Vehicle is overheating without gauges showing a problem. Had a mechanic check it out and the cooling fans are not working. I have seen there is a recall for this problem, but my VIN is not listed. This is a known problem, but RAM needs to widen their scope of vehicles that are affected by this fire risk.

The contact owns a 2018 Ram Promaster 2500. The contact received notification of the federal safety agency Campaign Number: 25V720000 (ENGINE AND ENGINE COOLING). The vehicle was started, and there was smoke coming from the exhaust pipe. The contact was unsure if any warning lights were illuminated. The contact took the vehicle to an AAA location and was informed to tow the vehicle to a dealer for assistance. The vehicle was towed to the dealer, where it was diagnosed that the low-speed radiator cooling fan failed to engage as designed, causing the engine to overheat. Due to the overheating, the engine became warped, causing a coolant leak into the cylinder, and causing escaped gases to enter the cooling system. The contact was informed that the engine and radiator cooling fan assembly needs to be replaced. The vehicle was not repaired due to the cost. The vehicle was towed to an independent mechanic, who replaced the engine and radiator cooling fan assembly. The manufacturer was made aware of the failure. The failure mileage was approximately 32,584.

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

The ABS warning light turned on when the vehicle reached approximately 82,033 miles. After driving about 100 additional miles, at around 82,133 miles, the braking system overheated and nearly failed, producing a burning smell and loud noise. The vehicle became unsafe to operate and left me stranded at night near Lonoke. I had to wait for the brakes to cool and then drive slowly to a repair shop the next morning. A repair shop confirmed that the braking system and parking brake were damaged due to lack of proper maintenance prior to sale. The full repair estimate was $1,257.34, but the dealership paid only $1,090.00 and refused to authorize the parking brake repair, leaving the vehicle unsafe. The vehicle had been driven less than 1,500 miles and for less than 15 days when this failure occurred. Additionally, this vehicle has 2 open the federal safety agency safety recalls that were not repaired before the sale, which indicates the dealership delivered the vehicle without completing mandatory safety repairs. This creates a serious safety hazard and could lead to total brake failure while driving.
