2021 RAM 1500 Complaints

In January I experienced a “backlite leak” that allowed water to enter the cab of my vehicle. As a direct result of this water intrusion, my RFH (Radio Frequency Hub) module failed due to electrical shorting caused by moisture exposure. This failure was sudden and completely outside of my control and was not the result of misuse, neglect, or normal wear and tear. Not to mention the risk it put my family in as I was driving with my wife and daughter when the module failed and caused total power failure. I was driving down the road with my family in the vehicle when without any warning the truck completely shut down and didn’t have any power. I brought it to the dealership I bought it from and they stated they fixed the leak and replaced the RFH. Fast forward to this past week, there was another leak in the rear window. The dealership then stated it was a faulty back window unit that needs to be completely replaced. Stellantis (formerly FCA) previously acknowledged this defect through extended warranty coverage. However, my vehicle’s model year was later excluded despite being affected by the same known issue. This exclusion is particularly concerning given that the defect ultimately caused collateral electrical damage beyond the window itself. Given the documented nature of this issue, its prior recognition under extended warranty, and the risk of safety it put my family in I wanted to document this issue

The leather-wrapped dashboard on my 2021 Ram 1500 is bubbling and delaminating on both the driver and passenger sides. The material is lifting and separating from the base, creating glare and reflections that impair forward visibility while driving. It also raises potential concerns with passenger airbag deployment due to the distorted/bubbling surface over the airbag module area. This is a widespread known defect on 2019–2021 RAM trucks with leather dashboards. I have an open case with Ram Customer Care (#96620269) where only partial coverage was offered. Attached are photos showing the bubbling/delamination on both sides. This defect affects safe vehicle operation. Please investigate.

On 12-4-2025 I purchased a set of kumho mavis mountaineers apt tires at the Thomson GA. location. They didn't balance the tires when they were installed. So I had to go back for them to be balanced. After 5 months my truck was still riding really rough and the tires had worn considerably more than they should have so I called Mavis about this problem and was instructed to go to the Evans GA location on 5-22-2026 for a tire inspection. This location said all for tires were dry-rotted and I haven't had these tires for 7 full months and have put 22,000 miles on them. One tire has worn to the point of being slick and this is the only vehicle my family has right now. This has been on going since the date of purchase and there is a good chance these tires will cause an accident.

I purchased a 2021 Ram 1500 North Edition (VIN: [XXX]) on XXX. As of last week, I noticed fluid leaking from under the engine compartment of the truck. I crawled under the truck and found that this five-year old truck has an oil pan that has rusted and rotted on the bottom and side leading to a leak of motor oil. I searched this online and found that this is a common issue amongst this model in this time frame and that it can cause a "catastrophic" loss of oil pressue while driving. I checked recalls and technical service bulletins and found no mention of this issue. Upon speaking with the service department of Hume's Chrysler, Jeep Dodge, and Ram of Waterford, PA, I was informed that they have seen this issue and that it is not covered by any warranty or recall because it's always caused by rust. This was only noticed because my wife's vehicle is in the shop and I parked in the garage causing me to notice it on the garage floor. My truck is normally parked in our gravel driveway and the oil leak went unnoticed. The truck was down approximately one-quart of oil when this was noticed. Had this not been noticed when it was, I fear that this issue could have caused an incident on the highway while the engine oil pressure was increased.

The contact owns a 2021 Ram 1500. The contact stated while driving at an undisclosed speed, there were abnormal sounds coming from the exhaust, the exhaust was leaking, and the contact discovered that there were cracks on the exhaust manifolds. No warning lights were illuminated. The vehicle was taken to a dealer where it was diagnosed that the exhaust manifolds and gasket needed to be replaced. The vehicle was repaired. The contact did research and was made aware of an unknown NHTSA Campaign Number however, the VIN was not included. The manufacturer was made aware of the failure and the manufacturer stated that NHTSA was responsible for adding each VIN to a recall. The failure mileage was approximately 80,000.

My 2021 RAM 1500 ecodiesel was subject to an NHTSA recall (23V-263). The recall included a replacement High pressure fuel pump (HPFP) due to a mechanical defect in the Bosch CP4.2 high-pressure fuel pump (HPFP) that causes the pump to fail prematurely and destroy itself internally. The HPFP was replaced under the recall over two years ago, only for the new fuel pump to fail catastrophically and send parts through the fuel loop. The failure has been confirmed by a manufacturer dealership service center (Huntington Beach, CA). The failure lead to immediate engine shutoff while driving in traffic. The vehicle could not be moved out of a busy street under its own power. There were no warning signs prior to failure.

2021 Ram 1500, rear window leaked after it rained. (Common problem with these trucks, even a class action law suit because of this issue). Leak was bad enough to cause severe electrical damage, truck will not start. There is an extended warranty related to this issue BUT according to Ram my truck does not qualify…..

Vehicle serpentine belt is faulty and has required multiple replacements. The belt has cause multiple close calls with traffic accidents

Made several stops and on the last one when I went to start the vehicle it wouldn't start. Used jump pack and it started. Had a non-flashing check engine light and a service ESC light. Decided to drive across town to auto store and have them check battery and replace if bad, When I pulled into the auto store parking lot the truck died and wheels locked up. (Very sudden stop) All four gear selector lights (PRND) were lit. Thought to myself "I'm glad this didn't happen on the roadway." Turns out the battery was indeed bad, and a new battery got me running again.

[XXX] Fire occurred while driving [XXX] my Ram 2021 and it was like a mini blast with a lot of sparks as I saw in a rear-view mirror.  Everything went out on the dashboard and the car stopped at the Top of Wolf Creek Pass [XXX] . I got out of the car and saw a small fire burning under the car. The fire under the car went out on its own. The very shape of the hole (perfectly round) in my muffler indicates an explosion that occurred simultaneously.  Also, the fused edges of the round hole indicate a high temperature during this explosion and fire. I disagree that this fair damage [XXX] my Ram 2021 3.0 ecodiesel [XXX] is considered from Progressive insurance as simple "wear and tear." estimate only $1669,78. Garber Collision Pontiac repaired the Ram 2021 by 04.24.2026 and replaced the damaged wiring harness ($1161 self-pay) as required by Progressive. After this repair, the Ram 2021 was unable to move and was delivered to the Tucson Ram dealer on 05/04/2026. The dealer did not indicate the root cause of the damage in the estimate. The car was also returned to me by the dealer. When I asked the dealer on 05.12.2026 to indicate the root cause of the damage, the dealer replied that he was not aware of such a similar damage and indicated that the warranty on the car has expired and there are no open recalls. But The dealer's initial assessment from 05.13.2026 (estimates $9325.25) indicates the fire was caused by a failure of the Exhaust Gas Recirculation (EGR) cooler, which is a known issue (similar to recall VB1/19V-757) where the cooler cracks, leaks coolant, and causes a fire in the intake manifold. This is a component failure resulting in an explosion/fire, not typical wear.    I need a diagnostic report that specifically mentions the EGR cooler failure as the source of the fire.
