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.
- multiple system failure. Truck presented with oil or atf leaking from the transmission bell housing and transmission inspection port cover. First detected by me at 30k mile oil change. Prior to this, my wife and I both complained that the truck was very slow to get into gear from a stop, especially while towing. Engine would rev and then finally dump power, spinning the rear tires. Additionally encountered hunting for gears on the highway. - second failure. 24 Aug. Truck illuminated with check engine light, traction control light, forward collision light, service ecs, service trailer brake control, and abs light. - inconsistent power application and loss of safety features makes the truck unpredictable and unsafe to drive. - truck is at the second dealer (first diagnosed issues as an oil drain plug). Has been at dealers for 32 days now. Problem is confirmed. - the suspected transmission issues have been noticed intermittently and getting progressively worse for about 6 months. Warning lights all appeared on the morning of 24 Aug. Truck was taken directly to the shop that morning.
