Ram 1500 lane assist problems

Filed Jun 24, 2026 · Driver assistance, Electrical · SC

When driving the truck the power steering would go out and make the truck almost impossible to turn. This is dangerous when driving as you cannot turn, avoid a collision, etc. I've had vehicles without power steering, and this was like the truck is actively pulling against you when trying to turn. The dealership did a diagnostic and said the power steering rack (electronic) needs to be replaced completely as it's going out. I'm not sure if it's related, but I've had other issues before this where my lane assist and cruise control would flash while in use and all turn off while driving down the road as well. There was no obvious check engine light or codes for this, just the occasional shutting off of my systems and power steering while operating the vehicle.

I was only allowed 3 components to choose from, but I want to make certain that Im including the these additional components that has been failing:Forward Collision Warning, Engine,Fuel/Propulsion System,Engine,Lane assistance/ Departure, and Lighting. There could be more to include but heres the dangerous issue I encounter everyday I utilize my vehicle,that has yet to be fixed nor addressed appropriately when I articulate EXACTLY what I feel,& see occur.My safety & everyone esle has been put at risk everyday which caused my 1st accident which I predicted was potentially likely since May 1,2025. It occurs exactly the same everytime just like the 1st terrifying experience: Id be stopped at a red light,intersection waiting for green light. With foot on brake between 5 to 10 seconds later I can feel the brake disenaging with my foot fully and physically on the brake simultaneously my vehicle screens will light up indicators erractically,(ghost touch,touch screen digitizer failure), while LUNGING FORWARD 5-7 ft on it OWNS,simultaneously screen blackout,& vehicle screen system reset followed by vehicle putting itself in emergency brake.This puts everyone around at RISKS AS MY VEHICLE OPERATES ON ITS OWN, which caused an accident at a red light where my truck plowed into the vehicle in front of me.Ive waited for an independent service contractor to evalute on 4 different occasions which they failed to appear or make contact on THEIR desired scheduled dates.The dealership has failed to reproduce due to unsatisfactory failed service repair attempts, discrepancies in verbal & documention.Absolute lack of concern for my safety or interest in issue, as at least 2 comeback services were met with breach of contract by dealer.The DEALERSHIP has been the only ones servicing my vehicle & according to their top tier diagnosis components successfully checked out in contrast to my many reoccurring service request for same issue.Prior to failure no warning lamps or messages appeared.

There was a recall for the cluster pack on the screen that shows my speedometer and safety features such a lane departure, turn signals, etc. I had the recall completed and my screen still blacks out randomly. It has been in the shop 3 times to fix the screen, but Ram cannot get it fixed. I have multiple pictures and videos of the screen blacking out if anyone is interested I can email them.

The contact owns a 2025 Ram 1500. The contact had experienced several electrical failures since purchasing the vehicle brand new. The contact stated that there was a sudden loss of power steering functionality, and the Lane Keep Assist would engage and normally vibrated the steering wheel; however, the vehicle and steering wheel continued to vibrate after the vehicle was centered. Additionally, the vehicle lost the instrument cluster image and power window functionality. The master window lock switch on the driver's side console had never worked since purchasing the vehicle. The failures were intermittent. The contact stated that occasionally, several warning lights were illuminated during the failures. The vehicle was towed to a local dealer where it was diagnosed, and determined that the TFT module needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the same dealer and was still being diagnosed. The manufacturer was informed of the failure and referred the contact back to the dealer for assistance.

The digital instrument cluster failed. All telemetry is shown on this cluster including speed, fuel level, rpm, odometer and more. The cluster was going totally black every two minutes and it would disable cruise, lane departure warning, blind spot warning and the check engine light was on. There was no indication prior that there was a problem, it just all of a sudden went black and beeped. Then it would come back after 5 seconds and do it again two minutes later. Also my odometer wasn't working or updating the miles. The dealer confirmed the cluster needed to be replaced. It sat at the dealer for 96 days before the repair was made.

All major braking and safety systems have failed, including the parking brake, 4-wheel drive, cruise and adaptive cruise control, lane departure warnings, blind spot monitoring, and parking collision alerts. These failures occurred at the same time, and we believe there may be additional issues not yet identified. Our local dealership (Barry Sanders Supercenter, Stillwater, OK) attempted multiple repairs before opening a service ticket with RAM/Stellantis. We were informed the part needed to fix the problem is backordered for approximately one year. This extended delay means we must continue driving a vehicle without critical safety systems or park it indefinitely, creating both a financial and safety burden. The loss of these features greatly increases the risk of collisions, especially in bad weather or on highways where adaptive cruise, lane departure warnings, and blind spot detection are essential. Online searches show this is not an isolated issue but a recurring problem in 2025 RAM 1500 models, suggesting a broader manufacturing or design defect.

Purchase truck and noticed on test drive steering wheel was off centered to the right by about 10-15 degrees.When Lane Assist was activated truck would drift right only to be alerted by the assist which would over correct steering to the left side of the lane.Lane Assist would just continue this effort to keep truck center.Truck has been aligned twice already and steering is still off centered to right.Back again to different dealership and tech ran EPS Flash and ran a steering angle calibration on EPS.Still not correct.Stored code was found as well C121A-00 Steering Angle Sensor not Initialized.Will continue working with dealerships till a solution has been found by engineering at RAM.I wish RAM would put this on a high priority fix, because I cannot use my Lane Assist safety feature.Due to steering issue..

150 amp fuse blew. Caused auxillary battery to die and the truck didnt start. Caused the check engine light to turn on and many features such as lane keep assist, adaptive cruise control, remote start, and auto start/stop didn't work. The manufacturer and dealer states that it's not a warrantied item. Thr 150 amp fuse connects both batteries
