Sierra 2500

  • 7,000 miles
Since day one with my 2015 GMC 2500 the transmission has acted very weird when driving. Every appointment I have made for service at the dealer I have complained about the shuddering and inconsistent upshifting and downshifting and of course the dealer tells me that they cannot find anything. Now it is to a point where transmission is shifting but the truck has no power some of the time. I feel like it comes and goes weekly. I also own a 2015 GMC 3500 that I bought at the same time but that truck resembles none of these symptoms.

While driving on dry pavement, driver moved knob on vehicle to switch from AWD to 2wd. Vehicle went into an immediate spin which could not be corrected. (or maybe it was because of what happened next). Vehicle careened over two lanes ("presumably" would not stop - driver does not recall trying to hit the brakes repeatedly or at all as the "next problem" was in front of driver and driver was focusing on survival).. driver quickly smashed through metal safety barrier and crashed through trees over a 30 ft embankment into a reservoir. Driver able to open roof while "steering" with left hand and opening roof with right hand as driver knew water was fast approaching. Driver smashed through trees, truck was demolished but driver was able to make it out of car alive as car took on water through opened roof. VIN number reports brake issues. Driver not aware of "brake recall" or any issues and did not report brake issue as an issue on scene as incident happened so fast and driver was attempting to stay alive and was ever focused on the next 'obstacle" as it was in the way per description herein. Airbags deployed as expected and driver exited water-filled vehicle via opened roof unharmed. GMC sent investigators out but no report has been issued to driver. Chubb lead investigator accompanied the GMC investigator and reported "no vehicle malfunction". after this incident, and reading others' problems, driver is now not convinced of that report.. no mention of brake recall seems to have been reported by anyone but by putting VIN number into this database.

Transmission control module failure; the truck at 45 mph developed a complete loss of all gauges(tach, speed, fuel, temp) and then 10-15 seconds later two loud noises followed by the vehicle coming to a rapid deceleration. This resulted in the wheels locking up and sliding sidewise. The truck rolled up on to its left two wheels and then slammed down. If this occurred at 75mph on the highway, the truck would have rolled. The truck has been at a GMC dealership since then. GMC has no date of if or when this truck can be repaired. The "tcm" is defective. It was on a city street, 45 mph zone going straight down a gentle grade.
