2021 RAM 1500 Complaints

I was coasting to a stoplight to make a right turn. Just as I am starting the turn the truck's engine shuts off. I have enough energy to make the turn and coast to a stop. I put the truck in park and started it back up. It was a busy intersection so luckily I had enough time to get out of the way, otherwise, this could have caused an accident. There were not any mechanical issues or warning lamps/indications before the truck shut off.

On at least 12 occasions since purchasing the vehicle new, when driving at low speed (below 20 mph) the vehicle stalls. The engine turns off, leaving the vehicle undrivable in the middle of a road. This presents a significant safety issue as it leaves the driver stranded and vulnerable of an accident. The hazard lights are automatically triggered. The following information presents on the screen: “park brake auto engaged. Press brake plus push switch to release. Safe hold temporarily disabled.” In order to re-start the vehicle, the ignition must be turned completely off and then restarted again. The check engine light is illuminated (sometimes) and other times it is not. When illuminated, the following codes are present: P1C64, Hybrid Perf. Engine Speed Below Target During Autostart. Dealership refuses to acknowledge the issue (says cannot reproduce problem). The problem is intermittent, but is a significant safety hazard for the driver, passengers, and others on the road. Most recently (today) the failure happened in the middle of a busy intersection with cars coming at me. The first failure happened with only 1,200 miles on the vehicle. Vehicle now has 27,441 miles and problem continues with no resolution from Dealer.

April 12, 2022 multiple warning lights ( check engine, electronic throttle, etc. ) appeared, screen warning to get to dealer to service. April 13, 2022 visited local dealer, earliest to service April 20, 2022. April 16, 2022 limp mode, restarted vehicle, restored normal operation with warning lights still showing. April 18, 2022, dealer serviced and stated fixed. April 19, 2022, warning lights and limp mode while driving on highway at 70 MPH. Managed to get to side of road in traffic, waited for break, turned around home. April 20, 2022 vehicle to dealer to repair. Still there as of April 28, 2022. "Star Case" opened. All diagnostics failed to locate problem, now trying various inspections / repairs per FCA technical. Dealer advises they have another similar vehicle ( 2021 Jeep Gladiator Eco Diesel ) with exact same situation so this is not one odd vehicle. Further extent of affected vehicles unknown. Safety issue due to vehicle going into limp mode with no warning, causing difficulty driving in traffic, especially at highway speeds, and risk of accident. Dealer and this owner note that all of this happened right after dealer completed recall for exhaust fluid software system. It appears likely that something done with this recall triggered these problems.

Was making left turn in neighborhood truck shot off . Came to stop automatically went in to park , emergency brake came on restarted truck turned off brake drove away.

Slowed down on residential street to make a right turn and after turn was completed the engine was off. There were no warning lights or chimes and engine stall was so smooth I didn't know it had happened. Auto start/stop was already disengaged as I do this every time I start the vehicle. Center cluster told me to shift to part and that auto braking (parking brake) had been engaged. The engine did restart as normal and was able to drive. All other accessories functioned as normal throughout the whole incident.

The truck just stalls randomly and all lights come on. Then it puts the emergency brake on. You have to put it in park release the the brake and restart it and hope no one hits you. I brought it to the dealer twice so far. I also called Chrysler customer care. I have a case# 82559049. They did nothing for me and I requested to speak to a esupervisor. I haven't heard back. Both times they say no fault codes, they never heard of the problem and cant duplicate. The second time they stated they updated the PCM software and said it happened in the morning with right turns... They now also put electrical and body systems and successfully flashed ECU from old part number to current part number. I never told them anything with right turns. I'm bringing it to the dealer today. They left a part hanging under the seat. The engine also sometimes tics when first started then goes away. I'm very concerned for my safety and if I have any passengers. First time under a 1k miles in May 2021 then randomly since then .Last time March 2022

Purchased truck with 4WD last November. Live in a snowy ice region. Truck randomly displays 4WD serv light and error message. Until the error clears itself, truck will not go into 4WD (four wheel drive), making it an unreliable vehicle during snow and ice storms, when traveling over the mountains, or when on dirt or sand roads. Additionally, this error can impact ABS functionality in some cases. Dealership has seen the truck four times, but has not fixed the issue. Now that the weather is warmer, the error is happening near daily.
