SERVICE BRAKES, ELECTRICAL SYSTEM
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.

SERVICE BRAKES, BACK OVER PREVENTION: WARNINGS
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.

ELECTRICAL SYSTEM, POWER TRAIN, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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.

SERVICE BRAKES, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
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.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, BACK OVER PREVENTION: WARNINGS, VEHICLE SPEED CONTROL
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

Vehicle at dealership a third time for same issue relating to U1412 code associated with ABS system. First time it was towed on 1/19/2026 and second time I took it to the dealership before it required towing on 3/26/2026. This time the truck required towing again after not being able to go into gear or being able to turn it off. Multiple warning lights on the dash. Still waiting for diagnosis but service department knew this problem from other vehicles and said manufacturer isn’t sure of cause.

Second incident relating to U1412 code where ABS related warning lights coming on. On 1/19/26 it had the same issue but was towed due to undriveable and would turn off. This time I drove straight to Dodge dealership where they got the codes, unlike last time due to batteries dead. Ram performed two flash updates and felt issue was fixed. Car is currently at dealership for third incident of same nature and had to be towed exactly same as first time on 1/19/26. Towed in on 4/16/2026. Three times when new truck less than 6 months old and 10k miles. Unsafe as mentioned on other report.

SERVICE BRAKES, VEHICLE SPEED CONTROL, ELECTRICAL SYSTEM
This is related to the 2025/2026 Ram 3500 U1412 code relating to anti lock brake system. On this date I got an ABS warning light and check engine light. The vehicle would not turn off, was not sure if it was in gear or not, and multiple other lights came on the dash. Vehicle towed to dealership. They said they could not reproduce the error and that all the codes disappeared due to the batteries dying overnight. They replaced both batteries and returned vehicle. Have since had same problem twice more with one requiring towing again. If this problem happens on roadway while being operated it would be very dangerous on roadway.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING
The contact owns a 2026 Ram 3500. The contact received notification of NHTSA Campaign Number: 26V059000 (EXTERIOR LIGHTING, ELECTRICAL SYSTEM); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact called a dealer while traveling in Braunfels, Texas, and asked about parts availability. The dealer stated that the manufacturer was providing only one part per week to the dealer location, which was causing a long wait for the recall repair. A second dealer, Miller Motor Sales Chrysler Dodge Jeep Ram (1196 Milwaukee Ave, Burlington, WI 53105) was contacted and confirmed the limited part supply to the dealer. The manufacturer was not made aware of the issue. The contact had not experienced a failure.

SERVICE BRAKES, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Shortly after purchasing a new 2026 Ram 3500 in January 2026, the vehicle began displaying multiple safety warnings simultaneously while driving. Warning indicators included Check Engine, ABS, Brake, Traction Control, Electronic Stability Control, Forward Collision Warning, and Automatic Emergency Braking, along with a “Service Electronic Stability Control” message. The vehicle had very low mileage when the issue first occurred. The vehicle was taken to the dealership for diagnosis and repair. The dealership indicated the concern involved rear wheel speed sensor(s) and the vehicle’s electronic control systems (including a Body Control Module software update). Multiple repair attempts were required, including sensor replacement(s) and software updates, with manufacturer engineering involvement. The dealership and engineering instructed extended test driving (hundreds of miles total) to verify the repair. A particularly concerning element is that a replacement sensor reportedly failed without producing a diagnostic code, meaning the driver may have no warning that a critical component failed until safety systems disable or the vehicle behaves erratically. When the issue occurs, multiple safety systems are impacted at the same time, including ABS braking, stability control, traction control, and AEB/forward collision systems. Multiple safety systems disabled simultaneously. Dealership personnel also indicated that these wheel speed sensors are experiencing widespread failures and that replacement sensors can fail again shortly after installation as they have a 67% failure rate, which raises concern that this may represent a broader manufacturing or component defect affecting multiple vehicles. This complaint is submitted to document a potential safety defect affecting braking, stability control, and driver assistance systems.

ELECTRICAL SYSTEM, BACK OVER PREVENTION: WARNINGS, LANE DEPARTURE: BLIND SPOT DETECTION
While driving, the instrument cluster/odometer intermittently flashed and became difficult to read for ~15 minutes. After parking, the odometer continued flashing for ~10 additional minutes. After the flashing stopped, the vehicle displayed “ParkSense Unavailable – Service Required.” On a separate date, with no trailer connected and without pressing steering wheel buttons, the cluster displayed a “Blind Spot Alert – Trailer Type (Conventional/Goose/5th) – Press OK to Select” prompt. These events were captured on video. Safety risk: driver information/warnings become unreliable while the vehicle is in motion, which is distracting and may reduce awareness of speed/vehicle status. No crash, injury, or fire occurred. A dealer inspected the vehicle and reviewed the customer video. The dealer documented stored electrical/communication/configuration faults consistent with the concern, including ECU configuration mismatch, lost communication with the trailer interface module, and communication bus off faults. The dealer performed software updates to related modules and road tested ~34 miles; the concern did not reproduce during the test drive. The vehicle also has an open safety recall (NHTSA 26V-059 / FCA 03D) for the trailer tow module with remedy/parts pending. Incidents occurred on 02/16/2026 and 02/18/2026 at ~3,000 miles, including after cold/rain conditions. One restart sequence did not immediately stop the flashing. Dealer scan recorded the following (stored) DTCs: TIPM B2204-87 (ECU configuration mismatch), TIPM U116B-00 (lost communication with trailer interface module), and ITCM U0077-00 (communication bus off). Dealer performed module software updates including CADM update per TSB 08-020-26 and PCM update per RRT-26-036. Recall remedy for 26V-059 / FCA 03D remains pending parts.

4 times in less than 4000 miles my 2026 trucks abs, cruise control, skid control, and check engine warnin07g lights have come on. I then have no anti-lock system, no cruise control, no 4-wheel drive, and no anti-skid system. Code reads-U1412. The dealer has replaced the rear speed sensors and it continues to happen. My truck is currently at the dealer in the service bay as I can't drive it. I've researched this and it's happened to many who have purchased this truck.
