STEERING
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.

ELECTRICAL SYSTEM, VISIBILITY/WIPER
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.

ELECTRICAL SYSTEM
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.

STRUCTURE:BODY, ELECTRICAL SYSTEM
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.

POWER TRAIN
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.

POWER TRAIN, FUEL/PROPULSION SYSTEM, VEHICLE SPEED CONTROL
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.

POWER TRAIN, ENGINE
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

FUEL/PROPULSION SYSTEM
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.
