What owners say about the vehicle speed control
Verbatim from NHTSA complaints, newest first
“Stellantis is recalling over 1.2 million 2019-2024 Ram 1500 pickups, including the 2021 model year, due to a software flaw in the ABS module that can disable the Electronic Stability Control (ESC) system My ram vin is not listed, but i am receiving this error.”
“I was driving on the highway going the speed limit and the car suddenly slowed to 35 and all sorts of lights (check engine light and others) came on and messages went across the screen about the throttle control and stability control. This is the 4th time this has happened to me. Each time I bring it to the dealer and am told "its a known computer glitch" or that there is a fix but it continues to happen again. Suddenly losing power and speed has caused other drivers to slam on breaks, swerve, etc. In order to reset the car I have to pull over on the highway to restart it. This is putting my safety and the safety of others at risk.”
“THE VEHICLE STARTS BUT WILL NOT ACCELERATE, and the necessary replacement part is still unavailable. I was informed that the manufacturer does not have the part in stock and that it needs to be manufactured, with an estimated arrival date of July 29th.”
“When driving home in the rain going 65+/- MPH my truck just shut off and turned back on, but was not able to accelerate. Had to pull off on the side of the road and the car started back up. This happened at least 5 more times on my 30 minute ride back home. When I finally got it home the truck would not cut off. I had to disconnect the batter which still did NOT stall the truck. Luckily I found a forum that advised to pull a specific fuse to cut the truck off. My biggest concern was that no warning lights or error codes came up on the dash it just went blank and came back on. The vehicle is currently at Roger Williams Ram Dealership in Weatherford TX. They have had the truck over a week and are still trying to figure out what the problem is. They have replaced a fuse box to my knowledge but this didnt fix the issue. I have video of the incident (driving with no power).”
“While driving on the highway with cruise control engaged, the system became stuck and would not disengage. I attempted to cancel cruise control using the button, tap the brakes, and shift to neutral, but none of these actions worked immediately. The truck continued accelerating beyond the set speed, putting my life and the lives of others in serious danger. I eventually regained control after repeatedly braking and forcing the truck into neutral, but this was an extremely dangerous situation that could have resulted in a fatal crash. To my knowledge, there were no warning lights or messages before or during the incident. I have not had the problem confirmed by a dealer yet, but I contacted the manufacturer (RAM customer service), and they instructed me to take the vehicle to a dealership for diagnostics at my own expense. This appears to be a serious defect in the cruise control or throttle system, and I am requesting a formal investigation.”
“I have experienced the engine surging while driving 2 times in the last 3 months. 10/18/2024. The RPMs slowly increase regardless of taking my foot off the gas pedal, slowing, or coming to a stop. The engine remains to rev. It causes me to have an extremely hard time keeping a maintained speed and gets difficult to slow down or slow to a stop. The truck was not on Cruise control, it was in 2-wheel drive, and the issue started right as I took off. The engine can be heard revving and trying to accelerate even in an attempt to try neutral with the foot off the gas to resolve the issue. I ensure I do not have my foot on the gas pedal and have to push my brake to the ground to stop. I have called our dealership who reports they are unaware of the issue I describe. Putting the car in park does not resolve the revving, which can be heard, and the Rpms fluctuations seen increasing stuck between 5-7. I have to completely stop and turn off the engine. I had pulled out and drove down a busy intersection I could not pull off on. The engine acceleration issue event lasted for about 10 minutes before I could safely pull off to turn the truck off. It was terrifying. If I had…”
