2019 Ram 1500 transmission problems

Filed Oct 12, 2026 · Electrical, Engine · AZ

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

This has now happened 3 separate times. Once 1 month ago, my husband and I were on the connecting road from [XXX] toward [XXX] by the water plants stopped in traffic and the truck completely powered off at a red light. It took 30 seconds for the truck to power back on, and be restarted. It showed a check engine light the rest of the drive. The next time it turned on from being off there was no check engine light. Last week we were driving on a the main road toward our house going 30 miles per hour and coming up to a right turn then the truck stopped abruptly and died. It completely powered off and took 2 minutes to power back on. We were blocking a one lane road. It then showed a check engine light that went away after a few days. Today after getting ready to enter [XXX] going 55 miles per hour the truck showed a check engine light and the truck started to power down mid highway entrance and I had to try and pull off before it powered down completely. It took 5 minutes this time for the truck regain power enough to be restart fully. The check engine light is still on. It endangered both me and everyone behind me because I abruptly slowed down and risked not having anywhere to pull over on a highway. Every time it has failed I have been in the middle of a road, lane, highway/freeway. With no way to signal my truck has died and no way to move it. Police have not investigated this issue, no dealerships or shops have looked at this issue currently. The engine, powertrain, brakes, and electrical appear to be not functioning properly in these incidents but it is unknown of the root cause. There has been no other indication that this truck has had these issues or previous recalls for these incidents. This truck was bought from a dealership earlier this year without issue.

I was on the highway when the vehicle alerted me that shift was unavailable then the auto start/stop was unavailable then the airbags were unavailable then my FUEL and my MPH were not reading. My windshield wipers started all on their own and could not be turned off! And my EMERGENCY LIGHTS WERE INOP. I LOST POWER STEERING and was locked in gear! All while in morning rush hour traffic on the highway! The vehicle gave me a notification to get to my destination before turning it off or changing gears because it would not go back into gear. I got off the highway as safely as I could without EMERGENCY LIGHTS OR TURN SIGNALS and proceeded to a stop light. While slowing down I had no steering control. I pulled over and had to force the wheel to turn then I attempted to accelerate to move and had no power. So I was stuck. I had emergency services come and tow my vehicle to Chevrolet of Homewood at that point who is currently looking at it.

The truck went into park from drive on its own . The emergency brake was also activated after going into park. The shifter knob kept switching from drive into park every time I slowed down at a light or stop sign.

System/Component Malfunction: High-voltage hybrid powertrain system failure. Code P0DAF-00 (Hybrid EV Battery Cell Balancing Circuit) is present and locked in the Hybrid Control Processor (HCP). Vehicle is available for inspection. Safety Risk: Operating a vehicle with an unresolved high-voltage hybrid cell balancing defect poses an immediate safety risk. Cell imbalances can cause sudden loss of motive power at highway speeds, propulsion shutdown, or an increased risk of a thermal event in the high-voltage pack. The manufacturer (Stellantis/RAM Care) refuses to provide a written safety determination, yet the dealer instructed me to continue driving a compromised high-voltage system on public roads until the failure worsens. Dealer Confirmation & Inspection: Confirmed and reproduced by authorized dealer (Ron Tonkin RAM) across multiple visits: Feb 25, 2026 (RO 502329): Code P0DAF-00 present. Dealer performed a BPCM software flash, which failed to resolve the underlying fault. June 2026 (RO 504097): Held for 10 days. Technician documented: "Scanned codes and found code P0DAF-00- Hybrid EV Battery Cell Balancing Circuit present but code is stored (not active) and also not stored in PCM, only the HCP." Tech test-drove 97 miles but corporate engineering (STAR) rules prevent parts authorization until the code migrates from HCP to PCM as an active fault. Dealer explicitly instructed me to drive it until it triggers a hard failure. Warning Lamps & Symptoms: First appeared Feb 25, 2026, via a yellow Check Engine Light. The light intermittently cycles on/off as the computer stores the code, but the underlying high-voltage defect is completely un-repaired.

While coming to a stop or slowing down, truck shifts into neutral on its own without driver input. Truck then makes you press brake and shift back to drive.
