| May 2026 | UNKNOWN OR OTHER | Vehicle serpentine belt is faulty and has required multiple replacements. The belt has cause multiple close calls with traffic accidents | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM,ENGINE | 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. | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER,ENGINE | [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 give my full consent for Ram Manufacturing to send an independent inspector to me for Ram 2021 3.0 Ecodisel INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: Yes | 143,171 |
| May 2026 | ELECTRICAL SYSTEM | 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. | Crash: No Fire: No | Unknown |
| May 2026 | ENGINE | The exhaust manifold on both sides of the motor have cracked and have broken bolts. The Ram dealer confirmed it and says it is a known issue that the manufacturer will not fix. With the crack and broken bolts, exhaust fumes are leaking out. It gets nauseating in the cab of the truck if the windows are up for too long. My independent mechanic is set to replace the manifolds with aftermarket ones due to literature saying the OEM will end up the same way. No dash lights have illuminated. | Crash: No Fire: No | Unknown |
| May 2026 | AIR BAGS,VEHICLE SPEED CONTROL | air bags, warning lamps on, it could be dangerous. don't know if it's been checked no accidents yet. | Crash: No Fire: No | Unknown |
| Apr 2026 | FUEL SYSTEM, DIESEL | The contact owns a 2021 Ram 1500. The contact stated that the vehicle failed to start and was unable to be jump-started. The vehicle was towed to an independent mechanic to be diagnosed, and it was determined that fuel was not reaching the fuel housing. The contact was informed that the CP4 high-pressure fuel pump was previously replaced under an undisclosed recall in 2024. The vehicle was then towed to the dealer, who had previously completed the recall repair. The contact was informed that the secondary fuel pump located in the engine compartment needed to be replaced; however, the repair would be an out-of-pocket expense. The vehicle was not repaired due to the cost. The manufacturer was not contacted. The failure mileage was approximately 85,000. | Crash: No Fire: No Towed | 85,000 |
| Apr 2026 | POWER TRAIN,ELECTRICAL SYSTEM,SERVICE BRAKES | I was only allowed 3 components to choose from, but I want to make certain that Im including the these additional components that has been failing:Forward Collision Warning, Engine,Fuel/Propulsion System,Engine,Lane assistance/ Departure, and Lighting. There could be more to include but heres the dangerous issue I encounter everyday I utilize my vehicle,that has yet to be fixed nor addressed appropriately when I articulate EXACTLY what I feel,& see occur.My safety & everyone esle has been put at risk everyday which caused my 1st accident which I predicted was potentially likely since May 1,2025. It occurs exactly the same everytime just like the 1st terrifying experience: Id be stopped at a red light,intersection waiting for green light. With foot on brake between 5 to 10 seconds later I can feel the brake disenaging with my foot fully and physically on the brake simultaneously my vehicle screens will light up indicators erractically,(ghost touch,touch screen digitizer failure), while LUNGING FORWARD 5-7 ft on it OWNS,simultaneously screen blackout,& vehicle screen system reset followed by vehicle putting itself in emergency brake.This puts everyone around at RISKS AS MY VEHICLE OPERATES ON ITS OWN, which caused an accident at a red light where my truck plowed into the vehicle in front of me.Ive waited for an independent service contractor to evalute on 4 different occasions which they failed to appear or make contact on THEIR desired scheduled dates.The dealership has failed to reproduce due to unsatisfactory failed service repair attempts, discrepancies in verbal & documention.Absolute lack of concern for my safety or interest in issue, as at least 2 comeback services were met with breach of contract by dealer.The DEALERSHIP has been the only ones servicing my vehicle & according to their top tier diagnosis components successfully checked out in contrast to my many reoccurring service request for same issue.Prior to failure no warning lamps or messages appeared. | Crash: No Fire: No | Unknown |
| Apr 2026 | UNKNOWN OR OTHER,ENGINE,FUEL/PROPULSION SYSTEM | The vehicle experienced an overheating condition immediately after being picked up from dealership service on April 11, 2026. Within a short distance of driving, a warning appeared and the vehicle became unsafe to operate, requiring it to be pulled over and towed. The dealership later stated that coolant was low but also reported no leaks. This condition should have been identified and corrected while the vehicle was in their custody prior to release. The failure created a safety risk because the vehicle could not be operated safely on the roadway and required immediate removal from traffic. The issue occurred without prior warning before the failure following service. | Crash: No Fire: No | Unknown |
| Apr 2026 | STEERING,SUSPENSION | I own a 2021 Ram 1500, which I purchased on March 29, 2024, as a certified pre-owned truck, and the primary issue involves a serious failure of the front wheel assembly. On three separate occasions, the front wheels have detached from the truck while it was in motion—on June 14, 2024, February 26, 2026, and most recently on April 17, 2026, when the left front wheel came off. I was driving the vehicle all three times during the incidents. Although the dealership has stated that repairs were completed after each incident, the problem continues to occur, indicating that the defect has not been properly resolved. The vehicle is available for inspection upon request, along with all supporting documentation. This defect creates a severe safety hazard, as losing the front wheels while driving greatly increases the risk of a crash and poses a danger to both me and others on the road. I have reported the issue to the dealership multiple times, and they have evaluated the vehicle, confirming a recurring and unresolved problem, along with additional major mechanical concerns that have not been adequately addressed under warranty. Despite having warranty coverage, I have paid high out-of-pocket costs for repairs, yet the problem has not been fixed. Despite these efforts, no effective or lasting repair has been made. The vehicle has not yet been inspected by the manufacturer, law enforcement, or insurance representatives, but I am willing to make it available for further review. Given the repeated and dangerous nature of this failure, I no longer feel safe operating the vehicle and I am requesting immediate assistance and a proper resolution. | Crash: No Fire: No | 53,806 |
| Apr 2026 | BACK OVER PREVENTION | the reverse camera quit working, trailer reverse function inop, service electric throttle light is on.

| Apr 2026 | STEERING,ELECTRICAL SYSTEM | July 2021 bought ram 1500 limited. $75k September 2021 3k miles took to dealer with REVERSE TRAILER STEERING UNAVAILABLE MESSAGES AND BACK UP CAMERA issues. Not fixed. Issues still happening. DEC 2021 ram 1500 recall y80 issued. RTSCM NEEDS updated. April 2022 dealer visit 11k miles recall y80 addressed and repaired. Issues continued. Several undocumented stop by dealer visits by request to look at while happening. Software updated each time. April 2023 purchasing dealer visit agin 26k miles. Up to this date vehicle was a lease. I bought the lease out with hopes to repair the issue. That dealer updated and also removed my dash to inspect the module. At this point as well 2 cases had been opened with ram themselves and I was wrote off as it will be fixed eventually. After that the issues never went away to this day but I was at a loss. A lemon law attorney told me that I didn’t have enough proof of the issue and i will share all my proof here with you guys. 2 month ago it froze the screen and accelerated on its own almost hitting a women and child pedestrian. I have had enough. I have worked hard for that money spent in the truck and cannot get the safety recall resolved. Now that the dash has been removed there are lights that shine in my eyes at night through the crease in the dash. All evidence cannot attach to this form because they are videos but I have over 65 showing proof and repair attempts | Crash: No Fire: No | Unknown |
| Apr 2026 | STEERING,UNKNOWN OR OTHER,SERVICE BRAKES | While driving, a deer entered the roadway. I applied the brakes to avoid hitting the deer and lost traction due to icy road conditions. The vehicle spun out and struck a utility pole. I later became aware of an open recall involving the ABS and/or electronic stability control (ESC) system for this vehicle. There were no warning lights, messages, or alerts before or after the incident. The vehicle did not maintain stability as expected during braking on ice. I am unsure whether the ABS/ESC system functioned properly at the time of the incident. The crash resulted in vehicle damage and property damage. To my knowledge, the vehicle has not yet been inspected by the manufacturer. The vehicle is available for inspection upon request. After crash, airbags did not deploy no fluids leaked no warning lights ever came on dash before or after crash | Crash: Yes Fire: No | Unknown |

| Mar 2026 | ELECTRICAL SYSTEM,LANE DEPARTURE,BACK OVER PREVENTION | 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. Unit removed again to attempt humidity removal- all electronics res | Crash: No Fire: No | Unknown |

| Mar 2026 | POWER TRAIN | RAM's 2023 recall addressed the engine shutdown problem in 131,700 of its half-ton 1500 RAM trucks equipped with the 5.7-liter Hemi eTorque mild hybrid engine. RAM said 1,500 5.7-liter eTorque models built between June 3, 2020, and September 12, 2021, had faulty software and needed a powertrain control module calibration update to fix the problem. Consumer complaints also exist that the RAM eTorque system has caused vehicles to shut down while in motion, which is by far the most dangerous problem attributed to it. My truck was built 08/2021 | Crash: No Fire: No | Unknown |
