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. This malfunction can endanger the lives of people on the road.

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. Others have gone months to almost a year without their trucks back on the road and GMC and Chevrolet do not have a replacement part, nor can they make any repairs to this module. Some have been told by the end of april they will have replacements, others have been told July-October of this year. This affects model trucks 2500HD and 3500HD years 2009-2015. This HAS TO BE A RECALL AND GMC/CHEVROLET/ACDELCO NEED TO REMEDY THIS PROBLEM ASAP.

Driving 70 on interstate 15 and the stabilitrak message came on the dash, truck went into limp mode, the truck went from 70 mph to 45 mph really fast. This was during rush hour traffic and I could have gotten in a wreck. This is a transmission control module and GM and Chevrolet DO NOT HAVE THE REPLACEMENT PART. It-??s on a nationwide back order

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. I think it should be fixed for free.

My 2015 Chevrolet Silverado 2500HD is now throwing a SERVICE TRAILER WIRING SYSTEM on the dash with nothing plugged into the 7way. Brakes do work on trailer and a dinging is present when hooked up but now the issue is on the truck without trailer being hooked up.

I was driving my 2015 Chevrolet Silverado 2500HD and towing my thirty foot travel trailer I suddenly received a banner on the center of my dash to "SERVICE TRAILER BRAKING SYSTEM" at which time I lost power to my trailer brakes. Not only did I lose power to my trailer brakes for the remainder of my trip but I also had to listen to a dinging noise for over 2 hours while driving. Between the brakes not working and the non stop distraction from the dinging, I did not feel safe at all along with worrying about my wife and kids who were also in the vehicle.

onstar/GPS system has failed and the built in navigational system shows that there is no GPS signal. There is also water leaking by the drivers side sun visor and above the parking brake. There were no warning signs of the problem with the GPS or onstar system other than when onstar was needed for emergency use it was unavailable and the built in navigation system was unable to be used because it showed up that GPS was unavailable.

I purchased this truck from a private seller due to its capacity to tow. After driving it for one day, an alert came up on the dashboard display saying "Service: Trailer Brake System". So I hit "Dismiss", but the alert keeps coming on and it is very intermittent and very distracting. Sometimes the alarm chime will continue for several seconds causing the driver to take their eyes off the road which is dangerous, but also, who knows what will happen when towing a trailer. I've looked it up online and this is an issue with many owners of the truck so Chevrolet should do a recall and provide a fix for this.

Water leak on headliner at sun visor or overhead console areas. Have reached out to Chevrolet dealership to address concern of issue that I was able to locate same thing happening to this year vehicle where tsbs have been identified to be told my VIN # is not listed.

Water leak on headliner at sun visor or overhead console areas, result of shark fin antenna. Vehicle not listed under vins for NHTSA tsb # 10089829 & 10089829. Vehicle has previously had dead battery which dealer claimed it was old battery, and therefore replaced my terminals and I purchased a new battery. My truck is a 2015 Chevrolet Silverado 2500 crew cab and is experiencing the same issue as this service bulletin is listing. Therefore dealer has stated it would be $120 to have outside company come in to inspect vehicle before and additional write up could be done and repair would be out of pocket.

My battery was dead this morning, so I jump started my truck. I let it run stationary for 10 minutes and the battery exploded. It sounded like a bomb went off. It blew the battery into pieces, electronics and the coolant resivoir. It sprayed battery acid, coolant everywhere. My ears were ringing as I was 10 feet from it. It also dented the fender on my truck. I contacted the local Chevy dealership and was blown off, was told I would be called back but was not. They said they had no information on problems with those batteries and said they couldn't get a resivoir for 3 days. We are traveling and stopped here in lebanon tn for the weekend. I have many more pictures, but they are too large to add.
