ELECTRICAL SYSTEM, UNKNOWN OR OTHER, EXTERIOR LIGHTING
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.

ENGINE, SERVICE BRAKES
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)

AIR BAGS
Vehicle Info: 2021 Dodge Ram 1500 Big Horn VIN: [XXX] Date of Incident: [XXX] Location: Exit ramp of [XXX] and [XXX] Problem Description: On [XXX], I was involved in a front-end collision with a tree while driving approximately 50 mph in my 2021 Dodge Ram 1500 Big Horn. The impact caused significant damage to the front of the vehicle, and around the vehicle, yet none of the airbags deployed. I experienced back and neck pain as a result of the crash. I believe this may indicate a failure or defect in the Supplemental Restraint System (SRS), crash sensors, or airbag control module. Injuries: Back pain and neck pain Thank you for your attention to this matter. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2021 Ram 1500 Laramie. 2 Occasions of unexpected engine Revving. 1) Pulled up to a stop, waiting for cross traffic, when fully stopped, the Engine began to rev up by ~500 RPM, up then back down, about 3 times in a row. Each time the truck tried to creep forwards, forcing me to step on the brake harder to prevent movement. Each engine surge lasted 1-2 seconds. 2) At low speeds (<20mph), car had similar RPM surges, but just caused some jerking. Both occasions occurred within 2-3 minutes of a cold start (~70 Deg F Env. temp). Certainly a safety concern, needs to be addressed.

The alternator with the etorque option. Truck is available upon request. Stellantis knows of the issues with the motor and doesn’t have a fix. The part to fix is on back order with no eta till available. I have been researching and some are without a vehicle up to a year. Dealers are aware of the situation. No warnings are shown prior to a total power loss failure. While driving home from work lights all over the dash lighted up and my truck was reading 9 volts. Luckily I was close to home and coasted into the driveway. My truck is now dead in the water sitting in driveway till when a part becomes available. I ended up leasing a car due to having no other option to get to and from work.

ELECTRICAL SYSTEM
Component: Motor Generator Unit (MGU) — part of the eTorque system on 2021 Ram 1500. What happened: I own a 2021 Ram 1500 with eTorque. In the year I’ve owned the truck, it has broken down twice due to major electrical issues. Most recently, it has been in the dealership’s shop for over 3 weeks due to a faulty MGU (Motor Generator Unit). There is no estimated time for repair because the part is backordered nationwide. Safety risk: The MGU failure caused the vehicle to become completely inoperable, leaving me without reliable transportation. I am concerned this issue could lead to a loss of power or stalling while driving if it had occurred under different conditions. Reproduction/inspection: The issue has been confirmed by the dealership (Preston Chrysler Dodge Jeep Ram in New Castle, PA). They are unable to proceed with the repair due to lack of part availability. The truck is currently sitting on the lot. Warning lamps/symptoms: Prior to failure, warning lights appeared and the truck experienced erratic behavior. The vehicle would not start after being turned off for a short period of time, and the RF hub had previously failed as well.

ELECTRICAL SYSTEM
The MGU of the 2021 Ram Laramie (e-torque) is not functioning properly and hampers the safety of the vehicle. The MGU, which controls the alternator, will not charge the battery beyond 13.0/13.2 volts during driving. As a result, when sitting for several days, the battery will not have sufficient voltage to start the vehicle since it is not charged fully during driving. Additionally, the MGU is now making a strange bearing noise so we will see if a failure is imminent. Considering this MGU controls the starting of the vehicle during stop/start, and the battery is not charging sufficiently to ensure the owner is not stranded, I consider this a significant safety issue (especially when I live in a place with winter of 8 months). I have not seen any warning lamps, but the charging indicator/screen shows 13.0 as below normal.

The contact owns a 2021 Ram 1500. The contact stated that while driving at various speeds, the front end of the vehicle shuddered abnormally. There was no warning light illuminated. The vehicle was taken to an unknown local dealer, where it was diagnosed and determined that the surrounding area of the CV axle and front differential was rusted. The vehicle was not repaired due to parts being on back order. The manufacturer was not made aware of the failure. The failure mileage was approximately 58,000. The VIN was not available.

When driving home in the rain going 65+/- MPH my truck just shut off and turned back on, but was not able to accelerate. Had to pull off on the side of the road and the car started back up. This happened at least 5 more times on my 30 minute ride back home. When I finally got it home the truck would not cut off. I had to disconnect the batter which still did NOT stall the truck. Luckily I found a forum that advised to pull a specific fuse to cut the truck off. My biggest concern was that no warning lights or error codes came up on the dash it just went blank and came back on. The vehicle is currently at Roger Williams Ram Dealership in Weatherford TX. They have had the truck over a week and are still trying to figure out what the problem is. They have replaced a fuse box to my knowledge but this didnt fix the issue. I have video of the incident (driving with no power).

I frequently receive a “Camera system unavailable” when I need it to safely reverse. The system will work randomly one percent of the time. An internet search reveals this is a common problem with the Ram 1500 but the manufacturer states that my VIN wasn’t included in the recall and directed me to reach out to NHTSA. Please help us have this vehicle included.

In April 2025 I reported a whining noise coming from the truck (under the hood), less than 50,000 miles. Dealer determined that the problem was a failing bearing in the Motor Generator Unit (MGU). They informed me that the truck was still under warranty and would be replaced... but that the part was on backorder with no date of arrival. They offered no rental and it is now 2 months later and the problem is worse. They tell me I can continue to drive it until it fails (REALLY?), that is the plan. Drive it until it dies and then what! It is now 2 1/2 months later, i try not to drive it due to the loud noises and fear of being stranded. They still have no eta on parts and have offered not help in resolving the issue. As I search online I see that this is not a new issue and that many people are having the same problem, no recall, no bulletin, no help! Just a $55,000 paperweight that I am paying for that sits in my driveway.

Engine light came on. Was driving ~25MPH on city street, in x-section of 2 major streets and heard loud mechanical noise, warning indicators audible and visual, and vehicle bucked and stalled within 100ft of when it started. After restarting vehicle was able to move about 20 more feet before losing power again. Brough to dealer, diagnosed with MGU (Motor Generator Unit) failure and battery that was defective due to incorrect charging. MGU part is nationally back ordered, with approximately 4000 replacement units on order with manufacturer, and 5 years of history of problems reported on owner chat boards and websites, both with brand new vehicles and vehicles that are just a few years old.

The contact owns a 2021 Ram 1500. The contact stated that while attempting to pull out of the driveway at 5 MPH, the transmission unexpectedly shifted into park and the parking brake independently activated, with the message "Auto-correct Shifter" displayed. There was no warning light illuminated. The contact shifted back into drive; however, moments later while driving on a neighborhood street at 25 MPH, the failure reoccurred. The contact shifted back into drive; however, the failure recurred twice more. The vehicle was towed to a local dealer where the vehicle was diagnosed, and the contact was advised that further diagnostic tests were needed to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 40,561.

ELECTRICAL SYSTEM, ENGINE
My Ram has the ETorque Generator that failed. It has caused the vehicle to suddenly stop and lose power. It first lost all electrical components in the interior. Then driving function shut off which includes the power steering. I was then driving down the street and it suddenly stopped and grinded into the park position of the transmission. The engine bay was very hot and I was surprised a fire didn't start. I hooked up jumper cables to another vehicle to get it off the road way as you couldn't shift it into neutral when the battery was dead. Pretty much all of the warning lights came on as I was still moving and they are still on. I took it into the ram dealer locally and they said there is 4379 that are in the same boat. There is no outlook to get replacement parts. I then took the Etorque generator out and tried having it rebuilt as there was no answer from Ram when it could be fixed. The place I took it to specializes in rebuilding alternators and they were able to fix the bearing problem in the generator but were unable to fix the function of recharging the batteries in the vehicle. So I have to put my truck on a charger every night so its charged up enough to make it to and from work. The vehicle has been inspected by a member of the Fergus Falls Fire Department and he is concerned with constant charging of the battery and electrical issues.
