Electrical system, Sep 16, 2026
I am writing to express my concern about vehicle warranty coverage being provided by RAM (Stellantis NA) on their vehicles. I have a 2021 Ram 1500 which has a motor generator unit (MGU) which has failed due to a defect with the bearings. This has been diagnosed by the dealership and identified as covered under the emissions warranty. This diagnosis was made by Kolosso Ram in Appleton, Wisconsin in June of 2026. At this time I was advised that it could be a 6 to 8 month wait for parts because of a parts shortage due to the demand for the replacement part. My vehicle has been out of service since April while I maintain loan payments, depreciation of value, insurance and have no vehicle for transportation. A call to Ram was unsuccessful on two occasions to obtain any kind of relief in form of loaner vehicle or faster procurement of the part. Ram continues to build vehicles with this MGU unit while customers are stuck with inoperable vehicles some of with are still under original warranty or covered by the emissions warranty. The failure of Ram to ensure that customers have working vehicles is causing undue stress both emotionally and financially. This is also a potential safety issue as failed parts could put operators in an unsafe position.

I purchased a new 2026 Ram 1500 Rebel Crew Cab 4x4 from the John Heister Dodge Ram dealership, in [XXX] on XXX. The following day, I day i was notified of an open safety recall (NHTSA 26V-531) affecting the vehicle's rear visibility/backup camera system, which under certain conditions may fail to display the rearview image during a backing event. I later confirmed that this recall was posted on XXX -- four days before I purchased the vehicle. The dealer, John Heister Dodge Ram, did not disclose this open recall at any point during the sale, and the vehicle was sold to me with the defect unrepaired. This is a known safety-related defect, as new vehicles are required to have open recalls repaired before delivery. The recall remedy has not yet been performed on my vehicle.

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

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.

I was driving at freeway speeds when the vehicle lost engine power and all the electronics in the vehicle stopped functioning. I was able to safely get the side of the road and stop the vehicle. Had vehicle towed to dealership. Tech inspected remote frequency hub (RFH) and observed corrosion on the circuit board. It looked as if water intrusion had occurred inside the vehicle, entered the RFH, causing corrosion and circuit failure. Believe intrusion occurred in the third brake light at the top of the cab. I am reporting this matter because a failure in the RFH caused the vehicle to stop functioning. I was lucky to be traveling on a straight, wide road and could safely get to a stop. I don't believe this would have been the case if I was on a curve or narrow road.

Electrical system shutdown including loss of all safety features (blind spot, emergency braking, abs, traction control, towing), climate control options (AC, Heat, window operations) and user interfaces (U-Connect screen, center gauge cluster). Initial warnings (2) on center cluster on listed- 1. Blind Spot Detection Disabled 2. 115 Volt Cargo Power Outlet On All electronics, controls were then disabled- black screens, inoperable controls. Passenger rear windows, sliding back glass, panoramic sunroof and drivers side mirror are the only working electronics other than speedometer. Upon inspection of all fuses, relays, battery, alternator, and checking all accessible wiring related to blind spot and auxiliary power and finding no defective issues, web searches were performed. Based on numerous other RAM owners on multiple forums on RAM trucks 2020 and newer with blind spot avoidance, we found a likely culprit in the driver's side brake light. Upon inspection of the left rear brake light assembly, a small hairline crack was located with signs of internal moisture/ condensation. After observing the internal moisture the drivers side rear brake housing was removed and disconnected for closer inspection and potential repair. While the driver side brake light assembly was removed, an instance occurred when my wife needed the vehicle. Upon and during the entirety of operation over the next 1.5 hrs driving approximately 63 miles, all electrical options worked as intended minus the blind spot avoidance and a new warning on brake lamps (obvious as tail light had been removed). During this time, the proximity sensor housing was removed from the assembly, water accumulation dried, and allowed to remain open next to a dehumidifier for 4 hours. Epoxy was applied over the hairline Crack, and any area that looked as if could be affected. Unit was reinstalled, however all electronic failure returned.

I am submitting this complaint to report a significant and unusual mechanical failure involving my 2021 Ram truck. The vehicle experienced a failure of the heater core assembly, which resulted in engine coolant leaking directly into the passenger compartment. This failure caused coolant odor and fluid intrusion inside the cabin and required extensive disassembly of the dashboard and HVAC system to repair. The total cost of repairs exceeded $5,300, which I believe is disproportionate and unexpected for a vehicle of this age and mileage. Two separate repair visits were required as it was found after the heater core was replaced the actuator on the driver’s side was damaged by the ongoing leak and required repair. The vehicle has been properly maintained and serviced according to manufacturer recommendations. While this incident did not result in an immediate crash or injury, the nature of the failure raises safety and health concerns, including: •Driver distraction due to coolant fumes and loss of defrost capability •Exposure of occupants to engine coolant within the enclosed passenger compartment •Sudden loss of cabin heating and windshield defogging capability in cold weather Given the age of the vehicle and the severity of the failure, this does not appear to be normal wear and tear. I am concerned that this may represent a design, material, or manufacturing defect that could affect other vehicles of the same model year. The odor was present for many months prior to the failure; however, the local dealership could not examine the issue at the time of a prior oil change due to lack of time on that visit. I am submitting this report to document the issue, assist in identifying potential patterns, and ensure appropriate review by the manufacturer and regulatory authorities. Repair invoices and supporting documentation are included.

I bought this truck used from a dealer in 2022. From the start the resting voltage of the car was a problem getting 12.7v and when I was driving it would often only get up to 13.4v. I took it to the dealer and they replaced it completely in 2023. It still shows low resting voltage and driving voltage. I told them and they said it was fine and not to worry. Now for the past 6 months it has been making a whirring sound that gets louder as I accelerate. I took it back to them and they said they didn't hear anything wrong, which is an outright lie. It still hasn't gotten better so I took it to a different mechanic and they said its a bad alternator and that they are very expensive and on back order. I tried setting up an appointment with the dealer to look at it again and they said I am now out of warranty and will charge me a diagnostic fee and if it is the alternator it again isn't covered by the warranty. I have been searching online and this is something thousands of other customers have been experiencing and there is a class action lawsuit about this as well. I am kindly asking that you look into this and if appropriate issue a recall for this. I shouldn't have to pay thousands of dollars to fix an alternator for a truck that only has 60k miles on it. My truck is only worth $29k so having to pay for a repair that is about 7% of my vehicle value is ridiculous.
