My vehicle has software that controls the rear gate, cameras, and my safety features for blind spots’seat buzzer to warn of collisions and voice activated phone system. I recently had a safety recall involving my back wheels locking up during driving. I had the recall done by Power Chevrolet and it affected my cameras, which I noticed were longer accurate immediately after leaving the dealership. My seat buzzer kept buzzing warning me of a collision due to the cameras inaccuracy. I am unsure if it affected my blind spot warning but my car was unsafe to drive as the safety features fill in many blind spots in this big vehicle. Additionally I had been having issues with my back gate opening when it should not resulting in two stops to close it’ one in Costco and one on [XXX] outside of Philomath, Oregon. These are safety issues. To get the software issues resolved, it cost an additional $210 for the updates and my back gate is still not fixed and no solution is offered. My fear is that people will be unaware their cameras or safety features are no longer properly calibrated and hit something or even worse, be unable to pay for software updates to make these features functional resulting in more crashes. I was unaware of the software updates ( I did all updates GMC pushed) needed to be done and this just continues on with more software updates to be released requiring future payments. I bought this car new and this was not disclosed or even discussed. GMC can push down updates that make other updates necessary and be an unending source of revenue for them. Oregon just passed a right to repair law but cars are exempt. This will result in unsafe vehicles on the road. My oil change cost me $350 with $210 the software updates. What were these safety related updates not done as recalls? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
