No appointments available at local dealers, trying to get it in, but not safe to drive.

On May 31, 2022 I purchased a 2020 Dodge Ram 1500 from Rountree Moore in Lake City Florida. I was sold this vehicle under the pretense that it had been safety checked and the vehicle was road worthy. On June 17, 2022 the front tires became low on air and I had to refill the air pressure in the tires. I was scheduled to go out of town for "Father's Day" weekend and the tires became a concern for me. On Saturday, June 18, 2022 I took my vehicle to Billings Tire in Providence, Florida to check the tires before taking my trip. I was informed that the two front tires must of be originals and never rotated and some of the metal was coming through the tires. Both rear tires were not the correct size tires for this truck and needed to be replaced although they were practically new. I called my dealership salesman, Justin, and relayed the issue to him. He in turn called Billings Tire and spoke with the owner and was suggested to Justin that this issue should have been caught during the safety inspection the dealer performs. I was also informed from Billings Tire that all 4 tires should be replaced because they were safety hazards. I spent over $900 on new tires that same day. I have been calling Justin about this issue and he keeps putting me off and tells me is General Manager is not in. It has been a week ago and no resolution. I feel as though I was highly pressured into purchasing this truck just to make a sale and the truck was NOT road worthy. I drive the interstate 5 days a week going to work. I feel I could have been killed as well as placing others in harms way at high speeds.

Rear sliding window frame cracks causing potential water leaks and mold if not corrected has been reported by multiple people of this happening to this vehicle

- Weare, NH, USA

The antenna on the posterior roof began leaking, causing extensive damage to the headliner, including the fabric around the rear airbags. Unknown level of destruction to the airbags. It is available for inspection upon request-Photos are also available. The vehicle has not been inspected by other entities at this time. A recent thunderstorm occurred and the headliner was immediately identified to have been damaged/stained. The dealership was contacted to see if this would be covered as a manufacturing defect, however there were no open recalls and the cost was expected to be paid by the customer. Upon self assessment, the leak was identified to be coming from the antenna. No applicable warning lamps or messages to include.

The incident has occurred three times since the first time it happened. While driving at various speeds on various types of roadways. The truck will completely shut off, power is quickly restored to the vehicle but at that point that engine has already shut off. Thus forcing me to come to a complete stop either in the middle of the road, or on the shoulder. The truck then had to be put in park, and then turned back on. This occurred three separate times, at three different instances. My safety, and the safety of my family was put at extreme risk during the instances due to the failure and leaving us stranded in the middle of several lanes of fast moving traffic. The lives of all other motorists around us were also put in danger due to the abrupt inability for me to continue driving, causing an interruption on several lanes of highway for many drivers. The vehicle is available for inspection upon request, it has not yet been inspected by a dealer, independent service center, police, insurance or other. There were no warning lamps, messages or other symptoms of the problem prior to the failure.

Eleven times now, the tailgate fails to fully lock when closed. It jams half way between being locked and not being locked. Only remedy I have found is to remove the tailgate partially and reinstall. This model has the Ram boxes. It appears there needs to be a bushing on the right side to keep the tailgate from shifting out of position.

Operating the vehicle at 35mph on a standard city street in Tucson, Az - River Rd. The vehicle flashes a system failure warning and then shuts off all power to the truck. This results in the transmission being thrown back into park and the driver having zero control over the vehicle. There are multiple online reports of this being fairly common on 2020/2021 Dodge Rams. The vehicle is being returned to the dealer, even if it is a minor issue it is a huge safety issue. I had zero control over the vehicle once the warning flashed. The abrupt loss of power and being thrown into a skid with no control is terrifying. Luckily there was no traffic. It is being returned and according to the dealership it will be investigated. Prior to that brief safety warning the truck had operated perfectly fine with no issues all day long with over 200miles logged for the day.

Plastic rear window surround frame crack.

- Staten Island, NY, USA

I have owned my 2020 Ram 1500 crew cab 4X4 for 8 months. The plastic frame that surrounds the rear window glass has cracked and caused the window to leak. This occurs both when the truck is in motion or is parked. This is a common problem that needs to be investigated because water can seep into the rear airbags causing the airbags to malfunction. Also with a crack in the rear glass frame the glass may explode causing harm to the back seat passengers.
