Oil pans are rusting through . Mine has 45,053 miles. In the 60k mile powertrain warranty. RAM refuses to fix because it is 'corrosion'. They want $1,861.53 to replace. These rusted pans are all over the internet.
On 10\09\2025 I was backing into a parking spot and when I was trying to adjust the position of the vehicle the power steering failed as I was backing up. After the power steering failed to work, the Power Steering Light appeared on the Dashboard. This is the first time this has happened. The safety issue is if I was going around a corner on the steering failed, my kids and I would probably be dead right now. Yes we live off a windy road. I left the truck parked at the shopping center overnight & it was towed to an Auto repair center locally. They told me to take it to the Dodge Dealership. The vehicle was towed to Pedder Dodge Chrysler on 10\10\2025. It is available for inspection.
Vehicles headunit no longer functions, backup camera system is also in-operational. Due to apparent over the air (OTA) updates to the uconnect infotainment headunit there is a widespread and known issue of, during the automated firmware update process, the vehicles battery being drained completely. This causes the vehicle to lose all power and the head unit to then fail the update process which creates a failure state for the headunit. In this particular case the headunit is "bricked" prescribled troubleshooting steps have been attempted but screen only displays: ("Software Update Update failed. Please re-insert USB Device.") according to a dealership service technician needs to be replaced. But there are none available for order. 2021 Ram 1500 BH UC 4 8.4" w/o nav.
Change in acceleration since purchasing truck. Discovered recently the fuel pump was causing the problem. Also the air bag light comes on and warning of a safety issue.
The contact owns a 2021 Ram 1500. The contact stated that while driving 40 MPH or slower, there was an abnormal whining sound coming from the engine compartment. While attempting to accelerate, the vehicle intermittently hesitated and slightly surged forward before accelerating. The failure had become more persistent over time. There were no warning lights illuminated. The contact found information related to NHTSA Campaign Number: 23V265000 (Power Train); however, the VIN was not included in the recall. The vehicle was taken to be diagnosed, and the contact was informed that the motor generator had failed and needed to be replaced. The vehicle was in the process of replacing the motor generator unit. The manufacturer was not informed of the failure. The failure mileage was approximately 140,000.
I am receiving a check electronic brake system alert. I can no longer use cruise control, traction control or four wheel drive.
The uconnect radio system freezes. It will do this and then reset. Sometimes it resets multiple times before working. It will freeze when using the backup camera. The entire screen will be frozen until it resets itself it takes approximately 60 seconds for it to reset.
The alternator has went bad on my 5.7 V8 E-torque motor and the alternator is on back order from Dodge and no dealers are able to tell the owners when the part will be available. My truck has been down for a week with no end sight. I have reached out to Dodge on several occasions and then placed on hold only to have my phone calls redirected to an State of Indiana Dodge dealer.
I put the car in drive and heard a loud bang. When I went to move it sounded like metal scraping. It turns out the front differential cracked and came loose making the truck inoperable. The truck was not off road and has been well taken care of. The part is three weeks on back order for a new front axle because this is happening to many of the RAM trucks.
While driving the vehice on 9/23/25, it randomly turned off while driving down my street. Took a while to get it started again, then once it was started, it would not turn off. I brought the vehicle to a local shop. There were NO warning lights.The next day they let me know that the issue was from a faulty sliding backlite, there were cracks on the frame by the back windows that caused water to leak down around the window into a control module that was filled with water that caused the vehicle to randomly turn off while driving down the street then later caused it to not be able to turn off. If this issue caused the vehicle to turn off while on a highway or a curvy road it would have almost definitely ended with a severe accident. I got in touch with stellantis and they know about the issue but aren't willing to help in any way.
I was driving on the highway going the speed limit and the car suddenly slowed to 35 and all sorts of lights (check engine light and others) came on and messages went across the screen about the throttle control and stability control. This is the 4th time this has happened to me. Each time I bring it to the dealer and am told "its a known computer glitch" or that there is a fix but it continues to happen again. Suddenly losing power and speed has caused other drivers to slam on breaks, swerve, etc. In order to reset the car I have to pull over on the highway to restart it. This is putting my safety and the safety of others at risk.
While towing, my truck threw P00AF-00 Turbocharger Boost Control Module "A" Performance and ABS C121C-00 Torque Request Signal Denied codes and I lost power due to turbocharger not engaging. Alarms that were lit included CEL, Service Electronic Throttle Control, and the Stabilizer system. The safety aspect is the loss of power while towing on a highway. The original code was cleared by my hometown dealer and vehicle ran well. 130 miles later it happened again, cleared by dealer in Parkersburg WV On the way home it happened a 3rd time. After parking for half an hour the alarm lights went off and I had full power. A day later the CEL also went off leaving no evidence of a problem on my dash. The vehicle is scheduled at the local dealer tomorrow (9/29/25) The trailer and truck combination was well within the towing limits of the vehicle. There are various threads in RAM owner groups that allude to this problem in the Gen 3 Ecodiesel The truck is under an extended warranty from MOPAR...hope they resolve the problem

My vehicle is currently at the service department of a dealership by my, Covert CDJR Bee Cave, due to two codes that recently set: P0EA7 and P026E. Mopar/Stellantis issues a TSB for this issue. Number 07-003-22. This is a known and documented issued but if your vehicle is outside the original 36 month, 36k mile warranty they will not cover it. This issue is not from wear and tear it is a defect and flaw in the original design. I have requested good will coverage and up to this point have been denied.
Failed fuel pump Needs a new fuel pump at 34000 miles. Vehicle currently at the dealership service department I saw there were previous recalls on these vehicles and their fuel pumps I should not have to replace a fuel pump at this mileage, ever
There is an exhaust leak at the manifold which lets exhaust gas int the engine compartment and it smells in the passenger compartment. I feel there is a health risk of carbon monoxide poisoning . It seems as though should be a repair made by the manufacturer.
1. The Motor Generator Unit (MGU) failed on my 2021 Ram 1500. The component is still installed in the vehicle and is available for inspection upon request. 2. The MGU failure caused a loud whining noise that worsened over two weeks, raising concern that the part could seize or fail while driving. A sudden failure could result in loss of vehicle power or drivability, creating a dangerous situation for me and others on the road. 3. Yes. A certified Ram dealership inspected my vehicle and officially diagnosed the MGU as defective. 4. Yes, the dealership confirmed the failure. To my knowledge, it has not been inspected by the manufacturer, police, or insurance representatives. 5. There were no warning lamps or dashboard messages. The only symptom was a whining noise that started faintly and gradually increased over the course of approximately two weeks before the dealer diagnosis.

Driving when a drunk driver ran a red light hitting me
I have a 2021 ram 1500 and the belt started to make a lot of noise. I got it to the dealership and they had it a whole month and a half. They said it was the alternator but no it was something called a MGU (motor generator unit). Can't find it no where in the country. Im stuck with a 50k truck that I can drive. Warranty can't fix it and now I can't sleep.
The rear defrost overheated causing the rear windshield to shatter
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.
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...
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.

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
2021 Ram 5.7 etorque MGU bad and vehicle sitting as part appears to be on nationwide back order. vehicle sitting while still making payments and paying insurance. seems to be major issue and no recall yet.
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.
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.
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.
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.
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
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.
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.
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)
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.
Mgu is out. Apparently there are 4000 on back order bc this part keeps failing on these etorque vehicles
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.

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.
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.
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.

NHTSA publishes every complaint as the owner wrote it and investigates only a fraction. Spelling, capitalisation and judgement are the filer’s own. What carries weight is repetition: the same component failing the same way across many filings, and whether the manufacturer eventually opened a recall for it.
