2020 Ram Promaster engine problems

Filed Nov 3, 2026 · Body, Engine · IL

I am writing to file this formal complaint regarding the purchase of a 2020 RAM ProMaster 3500 Cargo Van, which I purchased from High Quality Auto Group on May 11, 2026, for approximately $30,000. Before completing the purchase, I initially test-drove another vehicle that I was interested in purchasing. I was subsequently told by the dealership that the finance company would not approve me for that vehicle. The dealership then presented me with a different 2020 RAM ProMaster 3500 Cargo Van and told me that this vehicle would be a better option because it had fewer miles and was a heavy-duty model. Based on these representations and my understanding that this vehicle was a better option for my needs, I agreed to purchase it for approximately $30,000. Within 15 days of the purchase, the vehicle began experiencing serious mechanical issues. I promptly returned to your dealership to request assistance; however, I was denied service. I later took the vehicle to an authorized RAM dealership for a professional inspection and diagnostic evaluation. The diagnostic identified multiple issues, including: A coolant/antifreeze-related issue requiring service; A defective fuel pump; Failure of the air-conditioning system; and Abnormal engine noise requiring further diagnosis and repair. Additionally, after the purchase, I obtained a Carfax Vehicle History Report that revealed that the vehicle had been involved in an accident in 2024. I was not aware of this accident history at the time I purchased the vehicle, and this information was not disclosed to me before or during the sale, to the best of my knowledge. I later discovered that the vehicle I purchased had significant mechanical problems in addition to the accident history. These circumstances have resulted in financial losses, repair expenses, lost time, and disruption to my work. I respectfully request that High Quality Auto Group provide a fair and prompt resolution to this matter. I request consideration of one or more of

The vehicle is subject to two active safety recalls issued by the manufacturer, including a recall related to the rear backup camera system. The manufacturer has acknowledged the safety defects, but no remedy has been released for an extended period of time. The backup camera recall affects rear visibility while reversing, which poses a safety risk to the driver, passengers, pedestrians, and nearby vehicles. The backup camera intermittently fails or does not display an image as intended. The recall has been open for several months, and no estimated repair timeline has been provided by the manufacturer or dealer. I have contacted the dealer/manufacturer and was informed that no remedy is currently available. This vehicle is used regularly, increasing concern about continued operation with unresolved safety defects. The vehicle remains in service with known safety defects and no corrective action offered. This report is being submitted due to the prolonged delay in providing a remedy for acknowledged safety recalls.

On Sept 14 2025 we were driving our Promaster and heard a knocking sound then the vehicle immediately overheated. We had the car towed to a dealership and we were informed we needed a new engine as the fan module had failed causing the vehicle to overheat and ruining the engine. The extended warranty company also denied the claim citing that the fan module had failed. We purchased the vehicle on Sept 10th 2025. The prior owner had several repairs completed to the cooling system in the months prior to us purchasing the vehicle which included replacing the radiator, cylinder heads and gaskets as well as many other components. Per the dealership, there was a code that stated an overheating indicator showed approx 1000 miles prior to us bringing the vehicle in. The prior owner states that this indicator light never came on and it never came on for us either. When searching the recall database, our particular VIN does not appear to be included in the current recall, however the part number in question on the recall matches the part number the dealer is citing as the underlying issue which caused the engine failure and for the extended warranty to not cover the replacement. As for safety, the failure happened on a very busy highway requiring us to sit on the side of the road for several hours until we could get a tow company. The vehicle is currently at the dealer and they have plenty of documentation / photos of the damage and failed parts. No insurance company or police have been involved.
