Abs module has failed twice since truck purchased.
Check engine light turned on in my 2020 dodge ram 3500, I took the truck back to the dealership. According to them the Grid Heater Relay needs to be replaced & the truck could have caught on fire if we would have kept driving like that. I have done some research and saw that there has been a recall on that same part for the 2021-2023. Could it be possible the 2020 were defective also, this is a major safety concern and should be looked into. I also don’t believe the customer should be responsible for paying for this issue to be fixed when it was my family’s safety that was jeopardized.
On 12/4/23, at 6:37 am PST, we initiated remote start via the key fob. At 6:40 am pst, a flash and fire erupted from under the hood of the truck. We immediately worked to control the fire using extinguishers and garden hoses until the fire department arrived a few minutes later. They worked to put the fire out that engulfed the engine compartment and then worked to get the hood open to finish putting the fire out. The fire didn’t fully go out until the battery cables were cut.
While driving Down a paved roadway on 6/30/23 @ 5pm doing approximately 20 miles per hour the vehicle died and the dash lite up with every single message possible such as 4WD inactive, oil change due, fuel filter service required and etc. Attempted to restart the vehicle for about 25 minutes when another citizen noticed we were having issues with the vehicle so they stopped to assist us. The citizen towed my vehicle to location we were staying at for the weekend and upon arrival to the location I disconnected both battery terminals to allow the computer modules to drain/reset. After allowing the batteries to be disconnected for several hours I hooked them back up and tried starting the vehicle and was unsuccessful getting it to restart. I disconnected the batteries again for the night and returned the next morning to hook them up. after hooking the batteries back up,...

This Laramie trim level truck has an electronic drop tailgate with a button to drop the tailgate on the overhead console and one on the key fob. The tailgate on my truck was closed during my pre-trip and entering the vehicle. I had a trailer hooked to the receiver hitch and drove ten miles before realizing the tailgate was now in the down position and caused significant damage to the tailgate because the tailgate made contact with the trailer. With the electronic release tailgate on this particular year truck there is not a warning message alerting the driver that the tailgate is ajar. There is such an alert on newer models (2021-2022) I went to a local dealership to check. I’m sure the tailgate drop button somehow was pressed on the key fob while in my pocket entering the truck. But I did not receive any alert on the instrument...
