U1412 fault code: what 12 owners reported

3 times to date (10,000 miles/8 months) I have failing abs speed sensors. If I stop moving when all lights come on dash the truck is in operational. I cannot shift gears, put in park or turn engine off. Loose traction control, ads, 4wd, stabiltrac, speedometer. All assitive and braking functions. Code U1412. Dealer replaces speed sensors but problem returns.

…The following codes are; u0418, u04828, u1412, p1720, u0420, uc003, u0415. When I went to pick the car up some hours later it started right up like normal and halfway home which is approximately 3miles, everything lit up again this time the engine sounded rough and again I had to Coast to the right side of the road shut it off wait 10 minutes, start it up and I was able to get it home, where it's been since. I'm very concerned for my safety. From Reading, alot of others are as well.

P1DAB-00,U1412,P0716. VEHICLE HAS SHOWN CODES ABOVE FOR 5 PLUS MONTHS. CODES CAUSE VEHICLE TO SHIFT BETWEEN GEAR RANDOMLY. I HAVE TAKEN VEHICLE TO DEALERSHIP BUT PROBABLY WAS NOT RESOLVED; THE DEALERSHIP STATED THE PROBLEM WAS THE SPEED SENSOR, SO THE SWITCHED THEM OUT ONLY TO FIND OUT LATER IT WAS NOT THE PROBLEM. VEHICLE IS UNSAFE; ON ONE OCCASION THE VEHICLE SHIFT FROM THE 8TH GEAR TO THE 3RD WHILE ON THE FREEWAY ALMOST CAUSING AN ACCIDENT. PLEASE RESOLVE ISSUE BEFORE SOMEONE IS GRAVELY INJURED.

ON 1-14-16, WHILE DRIVING, HEARD A "THUMP" TYPE NOISE IN MY RIGHT REAR. THIS ALSO ACTIVATED MY CHECK ENGINE LIGHT. ALSO I NOTED SIGNIFICANT REDUCTION IN ABILITY TO ACCELERATE, AS IN THE CAR WAS STUCK IN A HIGHER GEAR. DROVE STRAIGHT TO MY LOCAL MECHANIC. THE CAR WOULD NOT TURN OFF OR GO INTO PARK. HOWEVER, MY MECHANIC LOCATED CERTAIN CODES IN HIS CHECK, BEING, P1DC7-00, P215C-00, P1DB6-00, U1412-00, AND P1915-00. HE THEN LOCATED A RECALL FOR THE 2013 DODGE CHARGER FOR A RELATED TRANSMISSION ISSUE. THE SAME "SYMPTOMS" ARE LISTED IN THAT RECALL, AS TO WHAT HAPPENED WITH MY CAR. THE SAME TYPE OF ENGINE (3.6 LITER, WITH 8 SPEED AUTOMATIC TRANSMISSION). I CONTACTED DODGE, AND THEY SEEMED LESS…

- [ ] U1412 implausible vehicle speed signal received - [ ] U0402 implausible data received from tcm - [ ] P0562 battery system/voltage low - [ ] P032f combustion engine producing insufficient torque Car completely shut off when attempting to turn onto Route 73 in NJ. The car was stuck in the intersection causing a threat to life and well-being of those not only in the Wagoneer but to the other drivers as the car could not be moved until towed. This took over an 1.5 hours to get towed and traffic had to be diverted by police.

Codes c2209-49, c2200-47, u0121, u11bc, u1110, u1412. ABS, traction control, brake and CEL iluminated. No speedometer and no power steering. Codes will not clear. All wheelspeed sensors are operational per scantool in live data mode. Issue not confermed by dealer or independant as the cost is outrageous. And i cannot find a recall to repair issue. These issues i have had since March 2024. Cost for me to repair would be approximately $1200. Safety systems like these should not need a recall they’ve had years to resolve issues with ABS problems. I’m hoping that Mopar sees these issues with other people and has a recall on the problem. My wife won’t even drive the truck.

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

CHECK ENGINE LIGHT COMES ON, CODES ARE U1504, U1412, U0001, U1110, U1120, WILL NOT SHIFT, 4WD TEMPORARY UNAVAILABLE MESSAGE COMES ON , STABILITY TRACTION LIGHT COMES ON, ALL SHIFTER GEAR LIGHTS ARE ON, THIS HAD HAPPENED 7 TIMES SINCE I PURCHASED THIS JEEP, ENGINE HAS CUT A COUPLE OF TIMES DURING ALL OF THESE ISSUES!

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.
