2018 RAM 1500 Vehicle Speed Control Problems

System involved: The vehicle experienced a sudden electronic/network failure consistent with loss of ECU/BCM/CAN bus communication. The instrument cluster, throttle control, and HVAC system became inoperative simultaneously. • Safety risk: While driving, the vehicle abruptly lost throttle response and critical driver information with no warning, followed by an uncommanded engine shutdown after coming to a stop. This created a serious risk of collision due to loss of propulsion, inability to react to traffic conditions, and lack of situational awareness. • Confirmation of issue: The vehicle was evaluated by an dodge service center, which identified an ECU software mismatch and performed a system update. The failure has not been intentionally reproduced due to safety concerns, but the incident is documented. • Inspections conducted: The vehicle has been inspected by an dodge service center. It has not yet been inspected by the manufacturer, police, or insurance representatives, as no accident occurred. •...

ABS light and traction control lights on, on dash. With these lights on, the cruise control and 4x4 do not work. One garage replaced front right axle, wheel bearing, brake rotor, brake pads, and ABS sensor. Lights were then out for a day but then came back. Took to a second garage and they replaced right rear ABS sensor. Lights went out for another day and then came back. They are still on. Because of Christmas it's been hard to get anyone to look at it. Also they say this is a known problem without any definite solution.

while driving the power steering indicator light came on, after 1 mile the power steering stopped working.

The abs keeps randomly disabling and then coming back on. When this happens, the cruise control is canceled which causes a sudden change in speed unexpectedly. Also, the 4x4 gets disabled. I believe the issue is this: hydraulic control unit can malfunction, impacting ABS, electronic stability control, and traction control performance software issue in the Anti-lock Brake System (ABS) control module that can disable the Electronic Stability Control (ESC) system, potentially increasing the risk of a crash. 

The electronic trailer brake system, anti-lock braking system, and electronics traction control system lights activate upon driving the vehicle. The cruise control is disabled when these warning lights come on as well. I've been informed by an ASE certified mechanic that the abs control module needs replacement. I've learned this is a known issue for my and similar Ram trucks and that Stellantis has the part on back order while it is in "engineering review". If my traction control, anti-lock brake system, and electronic trailer braking system is affected by a failed abs control module and it is a known issue across many vehicles and the part is in "engineering review" I belief this should be covered by Ram under a recall.

Intermittently loses ABS, traction control, and cruise control. Now throwing multiple error codes but does not "store" any codes. Lights/warnings/chimes are intermittent and random. Windshield wipers will intermittently come on as well. This is a known problem with these vehicles. Most recently randomly throws service shifter codes and vehicle shifts into neutral with no warning. The shifter has been replaced with no remedy to the problem.

In June of 2023, I was driving home and the vehicle became unresponsive, but still powered on. I was able to steer it partially to the side of the road. The gas pedal was unresponsive, all electrical was unresponsive and it also would not turn off. I called my husband, when he arrived about 20 minutes later we were finally able to turn off the truck, but electrical was still unresponsive so the windows would not roll up. I had just gotten off the freeway, about a mile, and was lucky to be in a residential area or I would have been unable to drive on the freeway. This is a major safely issue and I also had my 9 year old daughter in the truck with me. No warning messages or any symptoms prior to the problem/failure. We called and had it towed to our local trusted mechanic, Gray's...

Cam Shaft (RECALL) sensor failure / tone wheel per the dealership. Truck lost all power descending off a mountain / steep grade. Lost steering, brakes, engine power. The vehicle has only been inspected by the dealership. Truck will not start, even have installing new parts. It was towed in to the dealer on 12/2/23. I am not able to get a solid answer on what needs to be done. Communication has been very poor on the entire situation.

I purchased a new 2018 Ram Truck with an ECO Diesel engine. The engine has undergone multiple recall repairs including one for the EGR that could cause a potential fire hazard. The truck has been in service for multiple engine related issues since I purchased the vehicle. It has continuously had a rampant smell of antifreeze inside the cab of the vehicle which has made me feel sick on occasions and I must open the windows even in the winter months. After only 66,000 miles my truck suffered a catastrophic engine failure. Although Stellantis replaced the engine under warranty, the new engine only had a 2-year unlimited mileage warranty. 2 years has passed and the warranty is now no longer active and I am personally responsible for any repairs. My truck with the new engine has just over 60,000 miles and is suffering the same issues as the original engine...

The contact owns a 2018 Ram 1500. The contact stated that while attempting to accelerate from a stop, the vehicle failed to respond as needed. The contact stated that when the accelerator pedal was depressed, the vehicle was slow to respond. There were no warning lights illuminated. The vehicle was taken to the local dealer, who was unable to duplicate the failure. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 20,000.

ABS & TRACTION CONTROL LIGHTS KEEP COMMING ON, THEN THE CRUISE STOPS WORKING,

The problem is with the whole DEF System in the truck. for the last 6 months I can't go a week or less without getting some kind of code. Every time it effects the electronic throttle control and the truck goes into limp mode, I can be going 70 mph and it drops down to 30-40 mph no matter where I am at. I have almost been rear ended several times. I fix that code and a week later another code pops up and we do it all over again. I think I may have gone 2 weeks without a problem in the last 6 months. This time it is the DPF and DEF system, and here we go back into limp mode. I have had it to the dealer last week for issues which they couldn't figure out but thought that reprogramming would fix. So I leave to go...

The contact owns a 2018 Ram 1500. The contact stated while driving 60-65 MPH, the vehicle inadvertently started to decelerate while the contact was attempting to accelerate. The contact stated that after several minutes the vehicle returned to normal driving. The dealer was contacted and notified of the failure but offered no assistance. The vehicle was not diagnosed nor repaired. The manufacturer was not contacted. The failure mileage was approximately 34,000.

Cruise control on 65mph going down hill. Transmission dropped into a lower gear. Vehicle immediately slowed down immediately by probably 20-30 mph. Everything in vehicle was thrown forward. I struggled to keep control and thought I was going to roll and crash off of roadway, or hit another vehicle. This was not a problem for two years, until June of this year. Driven the same stretch of highway a dozen times without incident. 21,000 on vehicle now. I took the RAM tech for a ride to reproduce the incident. Did it on a small hill at 25-30mph and reproduced the problem several times at the same location of the hill. Transmission drops into lower gear, makes a kind of grinding or similar noise. Then it stays in this lower gear straining until the brake is pushed to turn cruise off. Told him of losing control on big hill and nearly...

My trucks display flickers in & out if I'm using GPS it changes flickers to other settings in display on it's own it makes phone call changes directions,changes control settings all by it self even if I turn off display settings it goes on by it self it is happening to many others who own the same year ram trucks this is a serious life threatening endangerment I almost have gotten into 4 accidents myself

I was traveling down a rural road with a 45 MPH speed limit, During acceleration the throttle on my truck stayed open, it accelerated to approximately 60 MPH and would not stop accelerating until I forcibly pressed the brake pedal. The truck was still accelerating even when I pressed the brake pedal. A couple seconds passed and then it finally depressed the accelerator pedal and I was able to slow down. The Throttle error light came on for around 20 seconds and then shut back off and the vehicle returned to normal. I am taking it to a dealership for review and hopeful fix of the issue.

I was driving and my high beams went out dash lights went out and windshield wipers went on on there own . I then came to a stop light and applied the break and all of the sudden the truck red lined and took off at full speed . I then turned the truck off to kill power to the motor due to it having electrical knob shifter and electrical transfer case This accident has caused my 3 hospital stays and 2 surgery’s

CRUISE ENGAGES INTERMITTENTLY WHEN IN MOTION, ENGAGES PROPERLY 50% OF THE TIME, NOT AT ALL AT OTHER TIMES. PROBLEM WAS FIRST OBSERVED AT 26,000 MILES.

TL* THE CONTACT OWNS A 2018 RAM 1500. THE CONTACT STATED THAT WHILE DRIVING 35 MPH, THE CRUISE CONTROL BECAME INOPERABLE. THE CONTACT STRUCK THE STEERING WHEEL WITH HIS FIST FOR THE CRUISE CONTROL TO RE-ENGAGE. THE VEHICLE WAS TAKEN TO GILLIE HYDE DODGE CHRYSLER JEEP RAM (1415 HAPPY VALLEY RD, GLASGOW, KY 42141, (270) 261-5305) TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE STEERING COLUMN NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 37,000. *BF THE CONTACT ALSO REPORTS THAT THE GEAR SELECTOR WOULD CHANGE AT RANDOM, THERE THE CONTACT DOES NOT DRIVE THE VEHICLE. *AS

THE PEDAL LAG WHILE TAKIN OFF FROM STOP THE PEDAL POSITION FREQUENCY ISNT CONSISTENT LOSS OF MPG COMPLETELY STOCK TRUCK ECO DIESEL CAN EVEN GET ABOVE 19MPG AVG LOSS OF POWER MPG AND PEDAL LAG ALONG WITH JUNK EMISSIONS THAT DESTROY ENGINES THEREFORE HAVE TO MAKE MORE PARTS OR TRUCKS ETC USING MORE FUEL TO POWER THESE MANUFACTURING PLANTS

I WAS DRIVING DOWN A WINDY COUNTRY ROAD AND THE CRUISE CONTROL ENGAGED ITSELF AND SET TO 90 MPH WHILE I WAS DRIVING ABOUT 50-55. CANCEL DID NOTHING, USING THE BRAKES CAUSED THEM TO SQUEAL BUT THE VEHICLE REMAINED ACCELERATING. I WAS ABLE TO DISENGAGE BY PUTTING THE ENGINE IN NEUTRAL AND USING THE PUSH BUTTON TO SHUT IT OFF.

DRIVING HOME FROM WORK. HAD USED CRUISE CONTROL AT 70MPH ON FREEWAY, BUT HAD NOT USED IT IN TOWN. I WAS DECELERATING FOR A STOP LIGHT, WHEN IT TURNED GREEN. I WAS PROBABLY TRAVELING 15-20MPH WHEN I BEGAN ACCELERATING AGAIN. I HEARD A CLICK, LIKE A RELAY OR SOLENOID AND THE VEHICLE BEGAN TO ACCELERATE AS IF I HAD HIT "RESUME". LAST SPEED PRESET HAD BEEN 70MPH. I WAS ABLE TO CANCEL THE ACCELERATION BY HITTING THE BRAKES, BUT I NEARLY REAR ENDED THE CAR IN FRONT OF ME. I DID NOT HIT "RESUME" BY MISTAKE EITHER, AS MY HAND WAS NOT ON THE STEERING WHEEL NEAR THE BUTTONS. IN FURTHER TROUBLESHOOTING, THE CRUISE WILL NOT ENGAGE BELOW 25MPH. IF RESUME IS PUSHED BEFORE PASSING 25MPH (DURING ACCELERATION), THEN NOTHING HAPPENS.

LONG LAG BETWEEN THE TIME YOU STEP ON THE ACCELERATOR AND THE WHEN THE TRUCK WOULD RESPOND. CREATED DANGEROUS SITUATION SPECIALLY MERGING WITH FAST MOVING TRAFFIC AND MOVING FROM STOP SIGNS. VEHICLE WOULD GO INTO LIMP MODE WITHOUT WARNING. IT WAS DEEMED TO A LEMON AND FCA BOUGHT IT BACK ONLY TO RESELL TO SOMEONE ELSE.

FROM NEW, THE RAM 1500 WITH THE ECO DIESEL ENGINE HAS HAD A SIGNIFICANT HESITATION WHEN COLD CREATING A SAFETY HAZARD. WHEN I LEAVE WORK I NEED TO CROSS A MULTIPLE LANE HIGHWAY HIGHWAY WITH A SPEED LIMIT OF 55 MPH. I COULD WALK ACROSS THE HIGHWAY FASTER THEN WHAT THE TRUCK WILL CROSS IT. I HAVE THE LATEST SOFTWARE UPDATE FOR ENGINE CONTROL THAT RAM IS OFFERING. I'VE TAKEN IT TO THE DEALER AND CONTACTED RAM CUSTOMER ASSIST ABOUT THE ISSUE. ALL I WAS OFFERED WAS A FEW FREE OIL CHANGES. BOTH SAY THERE IS NOTHING THEY CAN DO. I DID GET THE CUSTOMER ASSIST CONTACT TO STATE SHE WOULD RELAY THE MESSAGE TO ENGINEERING. I WILL SELECT TODAY'S DATE BELOW AS TO WHEN THIS PROBLEM HAPPENED, BUT IT DOES IT EVERY DAY IT IS DRIVEN.

TAKATA RECALL CRUISE CONTROL ONLY WORKS PART OF THE TIME. SOMETIMES WORKS THE FIRST TIME YOU PUSH THE BUTTON AND SOMETIMES YOU CAN PUSH IT NO MATTER HOW HARD OR SOFT 50 TIMES AND IT WON'T COME ON AT ALL. NO MATTER THE SPEED YOUR DRIVING.

TL* THE CONTACT OWNS A 2018 RAM 1500. WHILE DRIVING INTO A GARAGE WITH THE BRAKE PEDAL DEPRESSED, THE VEHICLE ACCELERATED AND CRASHED INTO THE CORNER OF THE CONTACT'S HOUSE. THERE WAS NO WARNING INDICATOR ILLUMINATED. THE AIR BAGS DID NOT DEPLOY. THE CONTACT SUSTAINED MINOR INJURIES THAT DID NOT REQUIRE MEDICAL ATTENTION. THE VEHICLE WAS DAMAGED, BUT WAS NOT TOWED. THE VEHICLE WAS TAKEN TO SIERRA MOTORS CHEVROLET CADILLAC BUICK GMC (209-984-5272, LOCATED AT 18475 5TH AVE, JAMESTOWN, CA 95327) TO BE DIAGNOSED, BUT THE CAUSE OF THE FAILURE COULD NOT BE DETERMINED. THE CONTACT STATED THAT THE FAILURE RECURRED. WHILE THE CONTACT'S VEHICLE WAS REVERSING TOWARDS ANOTHER VEHICLE, WITH THE BRAKE PEDAL DEPRESSED, THE VEHICLE ACCELERATED WITHOUT WARNING. THE CONTACT STRUCK AN INDIVIDUAL STANDING IN A PRIVATE DRIVEWAY. THE INDIVIDUAL SUSTAINED A MINOR INJURY THAT DID NOT REQUIRE IMMEDIATE MEDICAL ATTENTION. THE VEHICLE WAS DAMAGED, BUT WAS NOT...
