   A side detection module pin was corroded and was disrupting the electrical signals to major vehicle components, such as the dash (DIC). The DIC would lose communication with the rest of the vehicle while driving so no vehicle operation data was visible such as speed, alerts messages, etc. This likely also caused engine failure due to the incorrect operation of the afm which is on the same electrical circuit. No warning messages were given. The bad side detection module was…

   The car has all of a sudden had issues with the gas and breaking. When I press the gas, it stalls then rapidly accelerates. It has to be the transmission. Also, is making a noise and will barely drive when pressing on the gas. It does not accelerate!! Could have easily gotten into a car accident! What is going on??

   My vehicle randomly locks up and shuts off while I am taking a sharp turn or parking. A 'Service StabiliTrak' warning flahses on the dashboard. The steering wheel locks and the only way to get this warning to go away is to turn the vehicle off. This is a dangerous hazard as the vehicle can come to an abrupt stop in traffic.

   This is a very common problem with GM vehicles produced from 2015 to 2019 and is occurring in 5.3L and 6.2L gas engines. The engine coolant temperature sensor is failing and defaulting to a fail safe that turns the electric cooling fans on to full speed because it thinks the vehicle is overheating. When this sensor fails, the engine temperature gauge will not work. When the vehicle is turned off the fans will stay on for 15 minutes at full speed and will deplete the battery.…

    On our 2016 GMC Yukon Denali we have experienced intermittently working brake lights on our vehicle. We were first informed by a family friend following us that our passenger side was going in and out and now our driver's side brake light is completely out. The turn signal and reverse light still works but no brake light of any indication. No warnings or messages were given it just went completely out. I believe this is a safety hazard to myself and other driver's. It is…

    In my experience of transmission failure with my 16’ GMC YUKON, there was no warning. I had not experienced any issues with the slipping or jerking feel when accelerating or braking as described in the class action law suit. My vehicle had 105k miles, I took it in for regular maintenance including having the transmission flushed as I was told to do so for preventative maintenance. The transmission failed when I was traveling on the interstate with my family and I came upon…
