Filed Jun 8, 2021 · Brakes, Electrical · LA

While pulling a trailer, integrated trailer brake controller stopped working and disabled the trailer brakes. All trailer lights worked, just no brakes. Showed red warning in dash and "CF" on brake controller after failure. No warning before failure. Checked connections and tested with another trailer. Even with no trailer, warning is on and trailer brakes are not functional. Created hazard to driver and other motorists by spontaneous loss of brakes. Online forums indicate this is not an isolated incident. More recently, now the trailer running lights have failed. Brake and turn signal lights work, but no running lights. No police report of inspections. Not yet repaired. Available for inspection.

The integrated brake controller is intermittent at best. I purchased a trailer and it hooked up fine. Worked fine towing until I disconnected the trailer and seven pin connector. Now the controller tells me there is no trailer on the controller and the dash alerts. Upon pulling the trailer again the controller tells me I'm not towing when I am. ??

While in motion my foot brake does not send enough voltage to the electric brakes on my toy hauler 5th wheel trailer. I have to use the hand brake lever to safely stop the trailer.. While stopped my foot brake sends 3.4 volts to the trailer while the hand brake sends 12 volts (the gain is turned to its highest). With the ignition off, the brake lights on the truck to do not activate with the foot brake pedal. My local ram dealer does not know what the problem is, nor have they heard from chrysler. The appointment wit the ram dealer was on july 10, 2019.

When stepping on the brakes while pulling my 40 ft toy hauler power is not being supplied to the electric brakes. If the electric brakes are applied by hand then power is supplied. Also, the brake lights to do not come on on the truck when the foot brake is applied unless the engine is running. This truck has the factory installed integrated brake controller. The fuse for feeding power to the trailer brake is good.

Win modules and/or ignition switch randomly turns engine off and all electronics including trailer brake controls. Vehicle loss of power brakes and power steering. Loss of trailer brake controls. I was driving pulling a 10,000lbs. Trailer and truck was near impossible to stop. I was driving down the highway. Glad I wasn't driving around pedestrians, and no traffic, or driving into a city rush hour like I usually am. Now I don't pull a trailer anymore with this truck because I'm scared of smashing someone or something. A lot of people use these trucks as commercial vehicles and towing and this needs addresses before someone gets hurt or killed. *dt*jb *dt

The oem trailer brake controller will show a "trailer brakes disconnected", "check trailer brakes" this is a random message and checking the wiring shows no problems. The dealers appear to be clueless about the issue and blame the owners trailer. The warning on the dash display and on the oem trailer brake will display at any speed and without brake application. There are repeated posts on the various internet forums with no correction available, and since it is a intermittent problem, very hard to diagnose.

My driver was traveling at 80 MPH in cruise control when he started to notice a vibration from the truck that was shaking the mirrors. He took the vehicle out of cruise control and started to decelerate. At approximately 70 MPH a large bang was heard from beneath the vehicle and the front end of the truck was lifted off of the pavement. This caused the vehicle to be turned slightly sideways when it came back down into contact with the pavement while traveling at 70 MPH! Thankfully my driver was able to correct the vehicle straight but when he pushed on the brake pedal it went all the way to the floor. He was able to coast the vehicle to the side of the road and eventually bring it to a stop. Parts from the truck had been strewn down the interstate over approximately 200 yds. There was a vehicle traveling behind my driver at the time of the incident but luckily they were far enough behind that they were able to take evasive actions to avoid any flying debris. Thankfully there were no injuries or after incident accidents that occurred though I would attribute this to the alert and responsive driving of both my driver and the driver of the vehicle behind him. Had there been a vehicle directly behind or to the side of him there could have been a major accident possibly resulting in injuries or death. This vehicle was towed to a dodge ram dealer where we were informed that the front drive shaft was the part that failed. We were informed by dealer personnel that this drive shaft has a joint that is non-serviceable nor easily inspected and that this was the root cause of the failure. Other parts that were effected were the transfer case (the case was broken in two pieces and the internals were blown out), transmission cracked beyond repair, brake lines had been severed, fuel lines had been severed and a hole was punched through the cab bottom into the passenger area.
