2022 Ram 1500: check engine light

Filed Sep 19, 2026 · Electrical · TX

Dodge Ram Engine light and battery light turn on. I take it to a mechanic close to my house. Service manager connects the truck to the computer and vehicle shows error in alternator which. Dodge specific parts and he advises me to take the truck straight to dodge and not drive it anymore that the battery voltage is dropping and not charging. He sends me email breakdown of all error codes and tells me to give it to dodge. I drop off at dodge and provide all information to advisor including error codes. I tell them everything that happened and what the manager said about the battery voltage. They claim all information I provided wont all fit on the ticket so erases it and put basic information regarding voltage error. I offered to show him the pics and the report that was provided to me by other mechanic but he stated that they will have to do their own diagnostics anyway. Says that my truck has a bunch of software recalls that may clear the problem. I get a call they did a software update that cleared and fixed the problem and it wasn't the MGU. Vehicle was fixed and i could pick up. I pick up truck and the warning lights were cleared. Took it home no more driving. My 17 year old drives truck next day for school event, on his way to school event both lights turn back on. I tell him to come straight home we switch cars and i take directly to dodge. As i'm driving I'm paying attention to the voltage on battery, within a 10 mile drive to drop truck off at dodge the voltage goes from 12.? down to 10.9V. at 10.5 V the vehicles computers will lose power which can cause the power steering to go stiff, transmission to lock up or engine to stall abruptly mid drive. If this would have happened while my son was driving on hwy loop 410 in San Antonio (a major and very busy road) it could have been a disaster causing a wreck, potential loss of control or worse potentially ending in death or serious injury in a truck that was released the day prior as being fixed.

On XXX at approximately 1:00 PM, while driving my 2022 Ram 1500 3.0L EcoDiesel on [XXX] east of [XXX]/north of [XXX], a rigid metal diesel fuel supply tube fractured at approximately 49,209 miles. The failure caused a substantial uncontrolled release of diesel fuel into the engine compartment and underneath the vehicle. Diesel fuel traveled underneath the truck and contaminated portions of the rear of the vehicle. The vehicle's check engine light came on, became disabled and required repair away from home. The failed component has been retained. Photographs show a visible crack/fracture in the metal tube itself rather than at a threaded connection. A replacement Mopar tube was obtained from a Ram dealer. The vehicle previously underwent the Ram/Stellantis high-pressure fuel pump (HPFP) safety recall, Recall 01A/the federal safety agency 23V‑263, on XXX. I do not currently know whether the failed tube was replaced or disturbed during that repair and have requested the prior repair records. I am reporting this because a sudden pressurized diesel fuel leak into the engine compartment presents a potential fire hazard. I have retained the failed component and can make it available for inspection. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2022 Ram 1500 with the 5.7L HEMI eTorque system illuminated the check-engine light at approximately 88,000 miles with diagnostic codes P0AEE and P0BD4 relating to the motor-generator/inverter temperature sensing system. An authorized Ram dealership diagnosed a failed Motor Generator Unit (MGU) and stated that the MGU requires replacement. I was advised that continued operation could eventually result in the vehicle becoming undrivable, so I am storing the vehicle rather than routinely driving it. The dealer has ordered a replacement MGU but reports a severe national backorder and cannot provide an estimated repair date. Stellantis Customer Care has opened a case and is attempting to expedite the part, but has not provided an ETA. I am reporting this because the MGU is integral to the eTorque starting/charging system and the vehicle cannot presently be repaired within a known timeframe. I understand the federal safety agency has an existing investigation, PE24-018, concerning loss of motive power in 2022 Ram 1500 eTorque vehicles.

When it rains, the ESC, ABS and check engine lights come on. 4WD capability and is disabled and rear backup stopping is disabled. Steering becomes rough like it is locked in 4WD High but once dried out that goes away, and all lights except check engine light goes out. Mechanic reset codes and the next time it rains the scenario repeats itself.

Traveling down I64 Eastbound towing a 24' enclosed trailer loaded with 2 RZRs in my 2022 Ram 1500 Limited, a check engine light came on. I decided I'd get off at the next exit to have it looked at as we're one hour into a 3.5 hr drive. Within one or two mins of the check engine light dinging, another dash light came on in the form of a red battery with a lightning bolt. I had no idea what that was, but immediately after that light coming on, every light on the dash started blinking and the burnt electric smell flooded the cabin. I immediately put on the hazard lights and started to pull onto the shoulder and slow it down...but the brake pedal went to the floor and I had no brakes. I then steered the truck off the shoulder and into the grass and the soft ground (it was raining) helped slow it down, but we had to jump out of the truck before it had stopped as the overwhelming white smoke was about to asphyxiate us. The truck was down to about 5 mph when we had to jump out. The truck was completely engulfed in flames within just a few mins.

Purchased my used RAM October 2024. On 5 occasions the engine stalled while driving. Lost all power and rolled to a stop when the parking brake engaged. Most recent incident was May 17, 2026. I went to my dealer with this complaint May 14th, there were no codes and I was told truck was operating as designed. I am unable to duplicate the event - but it happens when I slow down and then speed up - Stop sign, parking lot etc. Potentially I could have run over someone or crashed or someone could have struck me. I received no warning before the stall. The check engine light did not come on. While stalled the following messages appeared on my dashboard 1. press brake and push button to start; 2. Shifter autocorrect active; 3. Park brake auto engaged press brake + push switch to release. The truck restarted but battery light remained on and the lightning bolt red light stayed on.

I am reporting a serious and ongoing safety issue with my Ram 1500. The vehicle has experienced multiple incidents of complete power loss while driving, including at highway speeds. During these events, the vehicle abruptly shuts down without warning. The dashboard lights illuminate (including the battery and check engine lights), followed by total electrical failure. The engine turns off, the radio and displays go dark, and I lose power steering and braking assist, then the emergency brake engages, making the vehicle extremely difficult to control. These incidents have occurred more than once and are unpredictable. In at least one instance, I was forced to pull over on the highway after the vehicle lost all power while in motion. The loss of steering and braking assistance created a dangerous situation, especially as I have had my children in the vehicle. After one incident, the vehicle was jump-started and the battery was replaced; however, the issue recurred. A mechanic previously reported that no diagnostic codes were found and no problem could be identified, despite the severity of the failure. The vehicle is currently at the dealership for further evaluation. This issue appears consistent with other reports of Ram 1500 vehicles experiencing sudden loss of motive power and electrical failure. The intermittent nature of the defect and lack of diagnostic codes make it difficult to detect, increasing the safety risk. I do not feel safe operating this vehicle, as it can shut down without warning while driving. I am requesting further investigation into this issue due to the significant risk of crash or injury.

Im driving vehicle and randomly the vehicle will shut off when making turns. It is random every so many months. But it has done in major intersections. It will immediately start back up so that’s good. But there are no engine lights. And dealership Does not seam like they can do a whole lot with engine no lights on. But it seems common when doing research online The vehicle is a 2022 Ram 1500 with 55,000 miles
