| Aug 2025 | STEERING,ELECTRICAL SYSTEM | Vehicle was a 2021 Ram 1500 (60k miles) with no known problems or issues. Drove home during during rainstorm truck operated normally. Next morning truck started normally with an error message "Power Steering Unavailable". Truck then began to run through a series of "error messages" and windshield wipers turned on and truck would not shutdown, unless you disconnected the battery. Towed to dealership and after several weeks of diagnostics with the manufacturer's assistance (due to the number of errors) it was determined the failure was the Power Steering Module. Once the Power Steering Module was removed, all other modules came back online and functioned normally. Even though the dealership has seen multiple failures of this type, it was not on the recall for this truck. Had this failure happened with my family in the vehicle while driving, it could have had devastating effects... | Crash: No Fire: No | Unknown |
| Aug 2025 | UNKNOWN OR OTHER | I was told by the dealer that the exhaust bolts for the Y pipe to the extension pipe are broken causing my exhaust to be louder than normal. My truck is 4 years old and I expect that the exhaust hardware would last longer than 4 years but apparently not. This condition may allow exhaust fumes to leak into the cab area of the vehicle potentially leading to someone getting sick or worse causing an accident from potentially loosing consciousness while driving. I went to a forum where they discussed this issue of the broken bolts on the Dodge Ram Trucks. | Crash: No Fire: No | Unknown |
| Aug 2025 | ENGINE | The MPU system was going out caused engine noises, the engine didn't sound like it wanted to change gears i drove very rough to the repair shop, it looks to be like a well known issue on Dodges with Etourqe they are 3 to 6 months behind in parts manufacturing | Crash: No Fire: No | Unknown |
| Aug 2025 | ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM | Driving to work and my truck lost all electrical power. All display lights turned on and hazard light signal started blinking but the hazard lights were not actually on. I then lost all electrical power; power steering, hazard lights would not turn on, all dash lights and display lights, head lights at first and then the battery died a couple minutes after that started. I could not put the truck into neutral so I could push it to the shoulder of the highway. I had to put it in Neutral manually with the pull tab under the steering wheel. My Ram 1500 5.7L hemi etorque was towed to Andy Mohr Chrysler Jeep Ram. The service shop told me that the motor generator unit is on back order and it could take a month or 2 months for the part to come in. | Crash: No Fire: No | Unknown |

| Aug 2025 | ELECTRICAL SYSTEM,ENGINE | I am submitting this complaint regarding a critical issue with my 2021 Ram 1500 equipped with the eTorque mild hybrid system. The vehicle has become inoperable due to the failure of the etorque alternator in this system. Unfortunately, Mopar—the official parts supplier—has not made this part available, and it has been on indefinite backorder for months. This is a known issue and has broken just outside of warranty. I'm in desperate need of this part and the backorder and supply time is unknown with no ETA. | Crash: No Fire: No | Unknown |
| Aug 2025 | STRUCTURE | I took my truck into the dealership for the second time because my tpms module was not functioning correctly. I would get an error about a mile into my travels saying it was unavailable. My second appointment the technician found the rear windshield is leaking water down through the back driver side and dripping water onto the module. Ram issued a previous recall for cars manufactured on or before Sept 30 2020. My truck was manufactured Nov 4 2020. The problem is the same but my truck some how was manufactured after the supposed fix date. It’s clear if you read on ram forums that tons of people are having the same issue. Rams fix is just sealing it but I have to pay out of pocket due to their failure of admitting the recall should go past Sept 30 2020 manufacture date. | Crash: No Fire: No | Unknown |
| Aug 2025 | ELECTRICAL SYSTEM,ENGINE | Our check engine light came on and we took it to get the code read. We had the code read by 3 independent sources and nothing came back on the code. There is currently a recall for this EXACT same issue with Dodge Ram 1500s from the exact same year but for some reason our truck VIN is not coming up as being on the recall. Now, we cannot pass smog in our state because the check engine light is on and the dealership does not have us on the recall for this exact issue. | Crash: No Fire: No | Unknown |
| Aug 2025 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER,ENGINE | Driving on highway lost all power sudden shut down of motor pulled off highway immediately ,autoshifted into park skidding in gravel unable to restart had towed to dealer,,they put in new under hood battery at my expense (was charging system failure) part needed was backordered. Got truck back home running lower than normal voltage local dealer claiming nothing wrong with it ,,diag from other dealership says otherwise,,,this isnt just a mechanical issue, its a safety issue as i drive alot. | Crash: No Fire: No | Unknown |
| Aug 2025 | FUEL/PROPULSION SYSTEM | After having the Fuel Pump replaced, it was revealed that there are wires above the fuel tank that have melted and are causing a fuel leak into different elements of the under carriage of the truck. The manufacturer is not willing to honor the recall and replace these parts (even though they are connected to the fuel system) so by their own logic this must be considered a separate issue. It is concerning that there is electrical melting occurring and causing a fuel leak right next to the effected area | Crash: No Fire: No | Unknown |
| Aug 2025 | UNKNOWN OR OTHER | The NoLimitz module cause my vehicle to shut off while in motion 1 time, and lose critical controls to safely operate the vehicle while in motion twice (power steering, gauge cluster, power brakes). Even though the engine still ran, once shut off it would not start again or go into neutral. I conclude the issue was the device as the power light on it was off (it should remain on when the ignition is in run or ACC as stated on the instructions from the manufactory). Once I un-plugged and re-plugged the module back in, everything returned to normal other than DTCs. | Crash: No Fire: No | Unknown |
| Aug 2025 | EXTERIOR LIGHTING | When the turn signal bar is in the neutral position, the right turn signal stays on. When the turn signal bar is in the left position, the right turn signal turns off, but the left turn signal stays off. This makes it impossible to signal left, and often causes the right turn signal to come on, which can be misleading to other drivers. | Crash: No Fire: No | Unknown |
| Jul 2025 | SERVICE BRAKES,ENGINE | When making a turn from a stop, the truck will kill the engine then engage the parking brake. I thought this may have been tied to Ram Safety Recall 37A, which I had fixed at the dealership, but the truck continues to have this issue even after the recall was fixed. This is not my video, but it shows what happens [XXX] Also, complaints about this issue can be found in this thread from a Ram forum [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
| Jul 2025 | ELECTRICAL SYSTEM,EXTERIOR LIGHTING,UNKNOWN OR OTHER | Went to start the vehicle with the key fob and the vehicle would not start. Had it towed to ram dealership and was told that the RF hub module needed to be replaced due to being damaged from water at leaked in from the rear window. Upon researching online forums, this seems to be an ongoing problem for this making model because of where the module is located. If there is not already in the works, there should be because this will continue to happen, especially where it rains a lot. | Crash: No Fire: No | Unknown |
