2023 Ram 1500: start-stop system problems

Filed Mar 17, 2026 · Brakes, Driver assistance · NY

The dash board showed the (A)auto start stop amd the (P) parking brake after hitting a puddle in rain. I brought the vehicle into the dealership for service on 4/18/2025 . They replaced the right rear caliper and EPB actuator and it temporarily fixed it. The lights still came on but would go off in rainy conditions. They came back on and didn’t go off so I brought it back to the dealership in again on 3/2/2026. First said they would fix the same part now after having my truck for 2 weeks claim it’s not the parking brake actuator but the main wiring harness and refuse to fix it under warranty of their work. I am now told by them they have to replace the entire wiring harness on my expense. Called customer support at ram truck and still haven’t heard back if they would do anything

The Auto Start-Stop system is not working properly. Three times it has failed to restart when sitting a traffic light. I believe this is safety issue because I could be rear ended if a vehicle is not aware of my vehicle not starting to move with traffic. The Auto Start-Stop can only be manually stopped by turning it off in the vehicle ever time to start to use it. This system needs fixed or there could be an accident on the road.

The auto start stop has malfunctioned 3 times in the last month when this happens the whole truck goes into stop mode the 1st 2 times I was at a stpop sign so it just made the people behind me mad this last time I was at a stop light where the speed limit is 55mph the light turned greeen and the truck shup off turned on the emergeny brake and would not move. I pushed as many buttons as I could the problem was I saw a semi coming in my rear view mirror and now the light is green and I'm not moving this is a veryscary thing

On approximately September 2024, after a few months of purchasing my vehicle new, the manufacturer installed battery died. This required me to jump it every time I needed to start it over the course of a week. A local dealership replaced it under warranty, though I noticed when I was driving the parasitic drain on the battery would continue. This repair was done through the Berlin City CDJR dealership located in Gorham, New Hampshire. I suspect if I drove long enough, critical systems would not function correctly while driving due to the battery dying. Today, I noticed the same issue arising. The battery died again, presumably from the same parasitic drain, and voltage was sitting around 10 amps. I would approximate that, over the past six months, the hybrid system has not been functioning as normal when I first purchased the vehicle. The trucks display notes why/when auto/start stop doesnt work. Over the past few months it displays that the battery is charging so auto/stop start is disabled, no matter how far/long I drive. It’s concerning to think what may happen if the hybrid system connected to the truck dies. The first time the regular battery died the display noted low voltage. For this most recent incident, it did not.

Related to auto start/stop. When coming to a stop, vehicle shuts off while still moving at 2-3 mph. Not just occasionally but EVERY time. Also, cannot park or put into reverse without vehicle shutting off too early, just to restart itself before going onto park or reverse. Took the vehicle in for recalls but did not change how auto start/ stop functions. Dealer could not replicate. Still to this day doing same thing.

On 19 November 2024, immediately after dealer performed an oil change and accomplished recall 24V‑653 and 24V729, on drive home vehicle engine shut off at a red light as normal (auto start/stop), but did not auto re-start. Had to power cycle in order to move truck. On 20 November 2024, vehicle engine shut off at a red light as normal (auto start/stop), but this time the SafeHold system engaged the parking brake and shifted the truck into park. The parking brake warning lamp illuminated. Truck would not move until the SafeHold system was manually bypassed. Surrounding traffic became impatient and took unnecessary risks to go around my truck that would not move. Immediately took truck to dealer for diagnosis and repair. On 22 November 2024, picked up truck from dealer with problem not repeatable, no repair performed. On 24 November 2024, exact same problem happened (vehicle engine shut off at a red light as normal (auto start/stop), SafeHold system engaged the parking brake and shifted the truck into park. The parking brake warning lamp illuminated. Truck would not move until the SafeHold system was manually bypassed). Surrounding traffic became impatient and took unnecessary risks to go around my truck that would not move

I brought the 'new to me' truck to the dealership 2 weeks after purchase to address a known recall and a Customer Satisfaction Notification. The latter related to the PCM software to address an issue of staling (08A). No problems were experienced before the service nor were any services noted on the Carfax for stalling before purchase. Four days after the recall and Customer Satisfaction Notice were addressed, I approached a stop sign with intentions to turn right. I slowed, but not to a complete stop, as I could see that no one was approaching from either direction and rolled thru the stop. I took my foot off the gas as I slowed (guessing to 3 mph) and applied the brake to make the turn when the engine stalled and engaged the parking brake and flashers. I was able to restart the vehicle following the dash instructions, however, this could have been a disaster if someone had been coming from my left of an impatient driver was behind me. The issue has not recurred since happening 3 days ago and the vehicle was taken to the dealership today (records of original visit and second visit attached). No warning message or sounds before the incident. Auto start/stop was turned on at the time.
