Nov 6, 2025SteeringElectrical systemBrakes

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 NHTSA 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.

When it rains water runs into the engine compartment and all of my wiring is dripping water. The service manager told me that they see this problem a lot and that they don't know how to fix it. I have looked online and there are many people complaining about this. Most people think it is the cowl leaking on the bottom of the windshield. I feel like if my wiring gets wet enough that I will have a malfunction.

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 2019 Ram Promaster (driver Only) verdict →
