2026 RAM 3500

Brand new 2026 Ram 3500 Limited Truck. Front parking sensors goes off when something is 15-25 feet away. Very frustrating as I have to turn off the front parking sensors. Had the same issue on my 2025 Ram 2500. Also, the tailgate is misaligned from the factory. Currently my truck is at the dealership, and they don't know how to realign the tailgate. No fixed. Again very frustrating on a brand-new truck from Ram.

On multiple occasions the U-Connect system in the listed 2026 RAM 3500 has gone completely black and was inoperable until a reset was performed. The trailer brake gain control and exhaust brake are accessed and controlled via the touch screen U-Connect system. This failure poses a significant safety issue when the screen goes black and the controls cannot be accessed when pulling a trailer. This can lead to failure to slow/stop the vehicle while in motion, tire failure on the trailer etc. The only method to regain access to the brake controls is to perform a reset of the U-Connect system which can take 2-3 minutes to complete. Stelantis is and has been aware of this issue for some time and has no resolution at this time.

The contact owns a 2026 Ram 3500. The contact stated that while driving at an undisclosed speed, several unknown warning lights were illuminated. The message that the trailer was not connected was displayed. The contact received notification of NHTSA Campaign Number: 26V059000 (Exterior Lighting, Electrical System); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The failure mileage was 11,000.

2026 Ram 3500 with <2700 miles. The trailer brakes are not applied appropriately when using the brake pedal, even though it will brake appropriately (with 1 of 3 trailers) while squeezing the manual override. This includes all brake levels (1-10 gain). When the trailer is disconnected, the truck will brake and show the appropriate level of pressure on the dash, though when the trailers are connected, one might press their foot 50% of the way down on the pedal while only 5% of the pressure is displayed on the dash and applied to the trailer brakes. This has nearly caused 3 separate accidents while towing (16,600 pounds total) when people merged and braked hard in traffic. Ram dealership initially refused to investigate until persisting and becoming very angry. At that point, the issue was confirmed. Brake module parts are pending replacement at this time. Their current "test methods" don't include an actual trailer and are insufficient to diagnose and identify the issue. There is no doubt that this will kill someone at some point. There was eventually a service trailer brake system message that popped up, though this wasn't persistent and went away automatically, not stored permanently, when the trailer disconnected. This message appeared previously approx 3 times, though there was no trailer connected to the truck at the time. Proximity sensors in the front and rear are also faulty, delaying notification of item in proximity, not displaying at all, or randomly being accurate. It also detects traffic that is a significant distance away. The same Ram dealership repeated the issue and called this "normal or expected behavior". It is, most definitely, not, and may present a danger to small children walking around the vehicle, pets, or potentially property due to the lack of notification of objects present.

Started with only 320 miles just days after purchasing this new 2026 RAM 3500 on XXX. I have taken the truck to three differ RAM dealerships as this issue continues to occur. [XXX]; [XXX]; and [XXX] Westside all had attempted to fix the issue. I had to return the truck a number of times to [XXX] and [XXX] for the same reasons. The following warmings messages are displayed: FCW/Cruise Control Unavailable Service Required - occurs when using cruise control, Service Electronic Stability Control, Auto Emergency Braking (AEB) Unavailable Service Required, Park Sense Temporarily Unavailable, Service Antilock Brake System, 4WD System Temporarily Unavailable, and Service engine light comes on. Two RAM dealers are saying the issue is the speed sensor, which has been replaced over three times. The RAM dealership had to open an engineer ticket with the manufacture, but the issue is not fixed. The Jacksonville service manger told me I can keep bringing the truck in, but until a different manufacture makes a new speed sensor, the truck will continue to have the same issue. I use the RAM 3500 to pull my RV. Brake system failure put myself and family and others safety at risk while on the road, therefore, I do not drive the truck in fear the brake system will fail and I won't be able to stop 20,000 pounds of truck and RV. The truck is available for inspection, but I am currently in the process of returning the truck under Flordia's Lemon Law.

The contact owns a 2026 Ram 3500.

Hello, I am formally documenting a serious safety incident involving my recently purchased 2026 Dodge Ram 3500 Tradesman 6.7L dually, purchased from Towbin Dodge in [XXX] , on May 9, 2026. On May 13, 2026—only five days after purchase—we were operating the truck for our dumpster business while towing a GN trailer loaded with approximately 5 tons. We were traveling down Mount Charleston after a pickup when a critical brake failure occurred. While descending the mountain grade, the truck’s braking system failed to respond. A warning light appeared on the dashboard indicating an issue with the electric brake system. We had tow/haul mode and exhaust braking engaged, but neither system functioned properly. When my father pressed the brake pedal, the vehicle did not slow down. With a steep descent ahead and no effective braking response, my father was forced to steer the vehicle off the road into a ditch to avoid a direct impact with the mountain, which could have resulted in a fatal collision. After stopping, we noticed signs of extreme brake overheating, and the system appeared to be close to catching fire. I have video and other documentation of the incident. The vehicle is currently in the dealer’s possession. This is a major safety failure occurring within days of purchase, and I am requesting a full investigation into the brake system and all related components, including any recalls, defects, or electronic braking malfunctions. I do not want the truck anymore! Given the severity and risk to life involved, I am requesting immediate action and a full resolution regarding this vehicle.

Vehicle sends cluster warnings about Auto Emergency Braking unavailable/inoperable, Electronic Stability Control needs service, Antilock Brake System needs service, Parksense Unavailable, and ultimately the Check Engine indicator illuminates after restarting the vehicle. An error code also is present in the computer, U1412. This has happened twice now in a two week period. These systems are critical to safe operation of he vehicle, especially in emergency braking conditions, and could affect both the operator and the general public if they indeed failed. The vehicle has not been inspected by the manufacturer, yet, and is scheduled for 5/8/2026
