2019 Ram 1500 electrical 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

The backup camera malfunctions, and glitches real bad half the time, and it sometimes happens while im using it at night. I feel like that could potentially be dangerous, and from a little research I have found that there are some recalls for this problem, but my truck isnt listed when I check the federal safety agency. database.

The cylinder that deploys the side curtain on the back passenger side spontaneously blew up in my truck. The vehicle was not currently being operated or on at the time is was parked in the driveway and was completely off. There was no forced entry and no collision it just spontaneously exploded causing roof damage, electrical damage, ceiling damage and cab light damage. The vehicle is currently parked at the dealership and has been verified by dealership that it was a mechanical malfunction with the airbag cylinder. There was no warnings that I was aware of before it exploded since it was just sitting in the driveway but from the information that was given to me by the dealerships this was an issue that fell under the Takata Airbag recalls in 2021. The only warning lights is when you start it up the airbag check system light is on the dashboard. This issue has caused me to never want to put my family in that truck again because thank god none of us were in it when it happened but this could have happened to anyone and thankfully we were not driving down the road or even in the vehicle at all. This is a major safety issue.

The 48-Volt Belt-Driven Hybrid Starter Generator / Motor Generator Unit (MGU / eTorque Alternator) suffered a catastrophic failure on my vehicle at approximately [Insert Mileage, e.g., 140,000] miles. The failure occurred while traveling out of state away from home, causing a sudden loss of vehicle charging, dashboard electrical errors ("Battery Saver Mode"), and creating an imminent threat of an engine stall in live traffic. Due to widespread manufacturer part backorders exceeding tens of thousands of units, my vehicle was forced to sit at a dealership until I could pay thousands of dollars out-of-pocket for a component that Ram has actively removed from newer production vehicles due to its high failure rate. This is a severe, systemic durability and safety issue affecting thousands of trucks. I am requesting that the federal safety agency force FCA/Stellantis to issue a safety recall and establish a retroactive reimbursement program for all owners who paid out-of-pocket for MGU replacements. I possess the official out-of-state dealership invoice and proof of payment.

The exact failed component has not yet been identified. The malfunction appeared to involve the vehicle’s electrical, communication/network, ignition or starting system. The vehicle and its components remain available for inspection upon request. On Friday, August 21, 2026, while driving my 2019 RAM 1500 Classic Tradesman with approximately 108,320 miles, the vehicle’s electronics suddenly began behaving erratically. As I braked and slowed nearly to a stop, the engine shut off. Parts of the dashboard remained illuminated, but the engine would not crank or restart. After approximately one minute, the electronics returned to normal and the vehicle started again. The truck then operated for the remainder of the drive. This created a safety risk because the vehicle shut off unexpectedly while it was still moving and temporarily could not be restarted. A similar electrical shutdown occurred on February 13, 2026, when the displays flashed, the HVAC cycled, vehicle power was lost and the key became stuck. The vehicle restarted after approximately five to ten minutes during that incident. The current problem has not yet been reproduced, confirmed or diagnosed by a dealer or independent service center. To the best of my knowledge, it has not yet been inspected by the manufacturer, police, an insurance representative or another organization. There was no advance warning before the electronics began malfunctioning during the August incident. The erratic electronics were the first symptom immediately before the shutdown. The dashboard remained partially illuminated during the no-crank period, but I do not recall the exact warning messages or lamps displayed. The vehicle’s VIN currently shows zero unrepaired safety recalls in the federal safety agency’s lookup.

My 2019 Ram 1500 Rebel has recurring electrical/communication failures that occur every day. The truck repeatedly displays “ParkSense Temporarily Unavailable,” “Service Shifter,” “Service Tire Pressure System,” and “Tire Pressure Unavailable.” The ParkSense sensors often do not activate at all, leaving me without parking assistance while backing up. The system also repeatedly pings with warnings throughout the day. When “Service Shifter” appears, the truck shifts roughly and the transmission does not feel like it is shifting correctly. I am concerned this could indicate an electrical or communication problem affecting the electronic shifter, transmission operation, gear selection, or vehicle control. The truck also has an ongoing water leak around the rear window, including the upper portion and near the sliding window. The electrical problems appear worse during high humidity, although they have also occurred during winter. I am concerned that water intrusion could cause corrosion, electrical shorts, module damage, or other safety hazards. A reputable independent repair shop inspected the vehicle and identified a U-code communication fault. The problems continue to occur daily. I am concerned about the risk of a collision from losing ParkSense, potential transmission/gear-selection problems, and water-related electrical damage. I am requesting that the federal safety agency investigate whether these recurring failures represent a safety defect affecting 2019 Ram 1500 vehicles. The vehicle is available for inspection.
