Adaptive Cruise Control Problems of Chevrolet Silverado 2500

Safety issue. The raised cruise control speed set button on the steering wheel is prone to being touched when rotating the steering wheel while making sharp turns when driving through parking lots at low speed. If the distance cruise was previously set at say 45 mph the last time it was used, and the set button is very briefly hit upward when rotating the wheel through your hands to the left, it can inadvertently cause the truck to start accelerating to that previously-set speed. The cruise button needs to be programmed such that at certain steering angles it will not respond to inputs. This is very dangerous. I Ave had this happen to me at least 5 times. Hitting the brakes stopped the acceleration. I reported it to the dealer as a potential engine surge but they could not reproduce it. I just recently realized what was happening. I believe this can easily be addressed by a steering angle lockout of the button. Other issues: drivetrain vibrates occasionally and shifts very hard (drivetrain literally slams through gear change) when leaving driving from a stop a slow speeds. Dealer cannot replicate. This diesel truck gets very poor mileage possibly from spending too much time in regeneration mode. Truck is super sensitive to fuel. Mileage varies drastically from fill up to fill up depending upon station. I believe the fuel cetane content affects regeneration in unexpected ways. I buy fuel at name brand stations but mileage varies drastically from vendor to vendor. Mileage average goes down to about 11 mpg much of the time due to time in regeneration. Dealer has no comments. I know hd trucks don't have official mileage ratings but this is just crazy. I drive light on the accelerator. Rarely achieved up to 21 mpg but average mileage runs about 11-12. I believe this to be a fault with these trucks as I have read complaints from many others. The infotainment system frequently loses all audio, including turn signal sound, nav. Gm has no fix. Possibly software.

While using adaptive cruise control, the system can detect a vehicle and immediately apply the brakes or slow down. In some cases, it may detect a vehicle (the vehicle icon appears) and trigger an immediate red collision light flash, followed by automatic braking. However, during these events, there were no cars ahead of the vehicle. There was no obstruction of sensors or cameras, and the incidents occurred in various weather conditions, including rain, snow, and clear days, both during the day and night. If the road is slick or slippery, this could potentially lead to a loss of control. Additionally, if another vehicle is following closely behind, it could result in a collision.
