I, [XXX] , hereby declare under oath that I have been a victim of fraud, negligence, and unfair business practices by Ford of Kendall. On [XXX], I purchased a 2020 RAM ProMaster 1500 HR (VIN: [XXX] ) for $45,906, based on the seller’s claim that it was inspected, certified, with a clean title and under manufacturer warranty, and eligible for an extended warranty.” A CarMax report dated September 28, 2025, later revealed that the vehicle had been involved in a severe prior accident that was never disclosed, valuing it at only $5,500 and causing a loss of over $40,000. Since purchase, the vehicle has only been operational for about four months, spending the rest of the time in repair shops due to serious and recurring mechanical failures, including leaks, oil contamination, and defects in the steering, transmission systems and other problems. Check Google reviews by [XXX]. The alleged “repairs” were...

formal complaint for gross negligence, warranty breach, and repeated mechanical failures involving my RAM 2020 ProMaster 1500 HR (VIN: [XXX] ).

Five days after the final delivery, the transmission failed again. in addition, there is a persistent problem with the steering system.

I am writing to formally file a complaint for gross negligence, excessive delays, and repeated mechanical failures regarding my RAM 2020 ProMaster1500 HR; VIN: [XXX] at the authorized dealership Bomnin-Doral in Miami, FL. The vehicle remained at the dealership for 1 year, 4 months, and 18 days due to transmission damage and other mechanical issues. Five days after final delivery, the transmission failed again. Despite multiple attempts to communicate, no effective response has been received, and the vehicle remains inoperable at my residence. A steering issue also persists: when turning the wheel fully to the left or right, it does not return to its original position and must be manually assisted, posing a serious accident risk, especially in turns under 90° or U-turns. The dealership claims this is “NORMAL,” which we strongly dispute. The transmission is covered by the manufacturer’s warranty, and other damaged parts by the GWC (POWERTRAIN PLUS)...

Transmission failure: Debris that caused the need for the 44A recall clogged the internal pump causing seizure. RAM service stated the need for transmission replacement, my cost.

The vehicle fails to go into gear when placed in DRIVE until the accelerator is pressed. It then shifts extremely hard into first gear and continues to shift with a hard thump into sequent gears until it reaches the higher gears. Extremely dangerous in city traffic. I managed to get the vehicle to a dealership for a warranty repair. They diagnosed the problem as a defective transmission. After five months of waiting, a new transmission was received and replaced. However, it didn't fix the problem. The dealership's fix was to order a second transmission. I'm still waiting with no ETA after eight months.

The transaxle downshifts whenever the accelerator pedal is released and the vehicle gains speed. This happens anytime, not when the driver wants to slow down. In the snow this has caused me to loose traction (unwanted engine breaking). There is no way to turn this off. I've spoken with other ProMaster owners and they all report the same issue. The transaxle should only offer engine breaking if the driver is depressing the brake pedal. Not whenever the vehicle accelerates. I believe this feature should only be active in "tow/haul" mode, and not be active in "Drive" mode. Even when the gear selector is in "manual mode" the unwanted downshifting still occurs. This has caused me to loose control (steering) as the vehicle is FWD on several occasions. No other vehicle I've ever driven acts this way. This has caused me to go off the road in snowy conditions.
