2021 Ram 1500 ClassicTransmission & drivetrainElectrical systemEngine & cooling

Complainant [[redacted]], a licensed contractor, master plumber, and master craftsman in [[redacted]], reports an unresolved, hazardous defect pattern on a 2021 RAM 1500 TRX (odometer: ~27,842). The vehicle features a 702-hp supercharged 6.2L V8 requiring specialized auxiliary cooling to prevent acute thermal derating, engine shutdown, and loss of motive power at highway speeds. BeginningXXX, recurring check-engine lights, "Intercooler Coolant Low" warnings, and confirmed DTCs P026E (Charge Air Cooler Coolant Pump...

Performance) and P0EA7 (Auxiliary Coolant Pump Control Circuit Performance) emerged, governed by Stellantis TSB 07-003-22. The vehicle was brought repeatedly to authorized dealer [[redacted]] CDJR ([[redacted]]) under Service Director [[redacted]] for safety remediation. Instead of curing the root electrical and cooling failures, the dealer engaged in a 5-month cycle of clearing codes, withholding Wi-Tech diagnostic logs, and holding the truck across multiple visits for over 45 cumulative days. During these extended holds, the vehicle suffered multiple deep-discharge battery cycles and parasitic drains, further degrading safety-critical electrical modules. The dealer then refused to release the vehicle without payment of an unsubstantiated $1,796.98 balance, unlawfully grounding a compromised vehicle while withholding proof of diagnostic repairs. Despite exhaustive pre-suit efforts, dealer management stonewalled all resolution. Formal complaints were logged with the WA Attorney General (File [redacted]), WA Dept. of Licensing (File [redacted]), and FTC (Report [redacted]). Active civil litigation is pending in Clark County Superior Court (Case [redacted]) with a 12-person jury pursuit. Chronic auxiliary cooling pump failure creates severe sudden shutdown risks in traffic. Federal defect investigation is urgently requested.

The RAM 1500 classic was bought at the end of September 2026. There were only 15,635 miles on the truck. On the steering wheel face there are two separate button panels, one on each side of the wheel. The left side controls the info screen on the gauge panel. The right side controls the manual gear +,-, as well as the cruise control on/off, set, reset, and cancel buttons. I tow/haul frequently. The driver needs to have manual control over the vehicles gear switching capability. Since day one, the entire right side...

controls has not worked. No lights, no codes, no indication that the panel is even connected to the truck in any way. Luckily, I believe this will be covered under the Carvana limited warranty. I am scheduling an appointment by Monday to get it evaluated. I am a new member to the RAM online forum. In the forum there are many many other RAM owners experiencing the same or very similar issues. Some have had some quite dangerous encounters due to the panel malfunction. What I find strange is there have been other recalls on RAMs all the way up to 2019. I am concerned about why the newer models, with the exact same issues, has not been issued a recall.

There are issues where the dash display goes blank and the headlights do not operate properly. The headlights will not switch from dim to bright automatically or manually. At times one or more lights will not even illuminate. It is not a constant problem but intermittent instead. We are not comfortable driving the vehicle after dark because it may happen at any time.

Odometer Fraud. The contact purchased a 2021 Ram 1500. At the time of purchase in June 2024, the vehicle mileage was 16,203. The vehicle was dealer sale. The contact discovered a mileage discrepancy while attempting to trade in the vehicle to another dealer, who presented a Carfax report listing the mileage at 16,244 in May 2024. Additionally, the Carfax report indicated that the vehicle had been serviced every 50,000 miles at Szott M-59 Jeep (6700 Highland Rd, White Lake, MI 48383). The contact stated the vehicle had never been serviced at Szott M-59 Jeep. The current mileage was 52,517.

On [redacted], I took my vehicle to Wallace Ram in Stuart, FL, for severe structural cracking on the exterior plastic rear window frame causing water to flood the cab. This failure perfectly matches Stellantis TSB 23-098-23. The dealer refused to help, and a Ram Senior Case Manager under Case #[redacted] denied coverage due to an arbitrary VIN exclusion list. The truck has 96,522 miles, is meticulously maintained, and has zero external impact damage. The frame fractured purely due to design failure. This unremedied...

defect poses severe safety hazards: 1. CHILD PASSENGER RISK: The water saturates the rear seat where two child safety seats are installed, compromising the structural environment and exposing young children to damp, unsafe seating. 2. MOLD HAZARD: Continuous saturation of foam seats and carpets has created an active mold/mildew biological hazard, posing an ongoing respiratory risk to my children. 3. ELECTRICAL STALLING RISK: Water runs down the cab wall, pooling over the Radio Frequency Hub (RF Hub). Water in this control module causes electrical shorts, leading to sudden engine stalling in traffic or complete vehicle lockout. They are leaving a family vehicle with an active hazard that causes property damage and threatens passenger safety. Stellantis has acknowledged this exact structural defect by extending the warranty to 8 years/150,000 miles for some vehicles under Warranty Bulletin U.S. D-23-17. However, by using a flawed and incomplete VIN population list, they are knowingly leaving my vehicle with a hazardous, active design defect that causes property damage and threatens passenger safety. I am seeking a full corporate remedy and a Goodwill Repair Authorization to permanently replace or structurally seal this defective assembly.

times, where the contact was informed that no failure was found and the failure could not be duplicated. Several messages and warning lights, including "Key Fob Not Detected", "Parking Brake Error", the ABS warning light, and the traction control warning light were illuminated during the failure. The dealer notified the manufacturer of the failure, and the technicians advised the dealer to replace the key fob; however, the failure persisted. The manufacturer was contacted and informed the contact that the vehicle was undergoing further diagnostic test. The failure mileage was approximately 98,000.

Original incident occurred in March 2026. While traveling at highway speeds my 2021 Ram 1500 lost all power and engine shutoff. I was able to get the truck to the side of the interstate due to it's momentum. Once I come to a stop, the e-brake is automatically applied and the vehicle will not restart or respond to any inputs from the keyfob. Vehicle is towed to nearest dealer, am told that the issue is related to an open recall that they have fixed and is now operating as normal. Less than one week later, the exact...

same thing occurs again, once again while traveling at highway speeds. Is towed into another dealer for service, and it is identified that the RF Module/Hub will need replaced due to a water leak. Repair is completed and vehicle returns to normal operation. 10/16/26 I attempt to start the vehicle with no success. After evaluating for a dead battery the vehicle is once again towed to a dealer (the same one that serviced it the first time). It is again identified that the RF Module/Hub will need replaced again due to a water leak around the back glass. I point out the Warranty Bulletin D-23-17 that would cover my vehicle and pertains to back glass water leaks. Am told by the dealer and Ram customer care that it does not in fact apply to my vehicle based on manufacturing date, despite it directly conflicting with the dates reflected on the notice. The TSB and the Warranty Bulletin appear to have conflicting dates for manufacture on them. This is incredibly deceptive behavior by Ram and should be looked into further. I have identified at least 8 previous complaints submitted to the NHTSA pertaining to the water leak/RF Module issue within the last 18 months along with acknowledgement from multiple service advisors at the dealerships that it is a known issue, yet no recall has been issued for it. Due to the potential and documented history of this leading to sudden power loss, it is merely a matter of time before this results in severe injury or loss of life.

The manufacturer defect involving stress cracks in the rear window structure (TSB 23-042-24) caused water to flood the rear cab wall along with the leaking rear cab air pressure vents. This water has short-circuited the CAN-bus network/RF Hub, causing active dashboard failures including 'Service Shifter' and 'ParkSense Temporarily Unavailable.' The vehicle is at immediate risk of locking in Park, stalling, or failing to shift while driving, creating an immediate crash hazard. Additionally, the exhaust manifolds are...

leaking, risking exhaust gas intrusion into the cabin. The dealership, Earnhardt Chrysler Dodge Jeep Ram at 1521 E Drivers Way, Gilbert, AZ 85297, has failed to resolve the water leaks over 4 separate visits this month." I was told a software update fixed the issue. Then at the last visit something electrical was replaced, the issue is still happening. The leaking rear cab air pressure vents have not been addressed in the previous 2 service appointments. This also allows water to leak onto the RF Hub

On August 11, 2026, following substantial rain, the engine unexpectedly stalled three times while the vehicle was being driven. The most serious occurrence happened at approximately 70 mph in heavy highway traffic. The engine stopped and gauges dropped to zero, while electrical accessories and infotainment remained powered. The vehicle restarted immediately but would stall again if shifted out of park. This occurred several times before staying on. No check engine light appeared at any point indicating an issue....

Other stalls occurred at lower speeds. I subsequently discovered significant recurring water intrusion into the rear cab. Water visibly drips from both upper corners of the rear-window area during rain and has saturated the rear seat and reached the floor under the rear seats up to the front passenger footwell. My children's car seats have been soaked. Moisture meter (pin based) readings confirm elevated moisture, visible mold has developed, and the interior has a strong odor. My VIN currently shows the manufacturer's XG1 extended warranty related to CHMSL water intrusion. I am concerned that water intrusion may have affected the RF hub, wiring, connectors, or other electrical systems and may be related to the engine stalls. The cause of the stalls has not yet been confirmed as I'm waiting on the appointment.
