I was driving on Interstate 15 northbound on March 6th, 2023. I was driving 70 mph, my truck dash had a message come on that said Stabilitrak needs service. Once this came on the truck dropped down to 45 mph during rush hour traffic. My truck is currently at Young Chevrolet in Layton, Utah because this happened again last week on Monday April 3rd, 2023. The Stabilitrak message came on and then my PRNDML indicator disappeared. I could not get the truck to go into any gear besides neutral and drive. I had to shut the truck off, wait then restart it. This happened when I was trying to back the truck up into my driveway and I was almost hit by another vehicle. The technician at Young chevrolet said my TRANSMISSION CONTROL MODULE WAS BAD, from my own research of online forums and social media pages, there are numerous others with the same exact problem. …
I purchased this 2015 pickup as a preowned vehicle in March of 2022. Only a few months later and 2,000 miles, the service trailer brake system warning chime activated over and over again. This happened randomly without any apparent pattern. It happened primarily when no trailer was connected. It has continued to get worse and more frequent. When it starts to chime the message and chime doesn't just come on once it chimes over and over again for entire drives lasting hours. This problem has gotten worse by becoming more frequent. This is so bad that it is very distracting to me as the driver. It takes my attention off the road and not only that it causes me a headache from the constant annoying chime. This is very unsafe whether towing or not. It is even more dangerous when towing a vehicle as it is unknown if the trailer brake system will work in any moment of need. …
While pulling my camper trailer the brake controller failed. It would turn on an alarm (visually) and ring an audio alarm. Every time it would come on, I would stop on the highway and recheck the trailer connection and that was Ok. Every time that I get this alarm, I have no trailer brakes. This has happened for the last 3 years. This happens at any speed and in any road conditions and weather. My trailer is 9000# and without brakes it could be dangerous to stop. especially in an emergency situation. My dealer says it can't find anything wrong with the truck. I went on line to find some solutions to the problem and found out that this is quite common. People were saying that we should report this, so here it is. I have replaced the plug on the trailer and the truck with no luck. The dealer is presently replacing the TRAILER BRAKE MODULE. Thats about $1000. …
