problem #7

Dec 202016

Sierra 1500

  • 39,000 miles


On Tuesday, December 20th 2016 at approximately 7:15pm while driving South on new river road in Lincoln ri I tried to make a left turn onto a side street. When I turned the steering wheel left it was snatched out of my hands and the steering wheel automatically turned back to center it self. I could not manuver the vehicle as it rolled up onto the sidewalk where I had to use the emergency brake to force the vehicle from rolling into a tree. The vehicle dic displayed "park assist" and afterwards the vehicle went completely dead...no lights or sounds when I tried turning the key to restart it. Lifted up the hood and all the electronics came back on and vehicle started. Dic prompt displayed "open and then close the driver side window" had vehicle taken to dealer for service.

The contact owns a 2015 GMC Sierra 1500. While driving 55 mph, the defroster stopped working and the air conditioner was blowing out hot air. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was 46,000.

Headlights are the worst I've ever seen. Very unsafe to drive and night and extremely bad in the rain.

The infotainment screen is very distracting when driving at night. Regardless of the system displayed, (radio, phone, or just the clock/off screen), the lighting is too bright. This is extremely distracting to the driver. The dash light dimmer control switch works the dash lights and the infotainment screen. If one were to dim the dash lights so that the infotainment light is low enough to be acceptable, then the dash lights are too low to be effective and used. The infotainment screen should have a separate remote switch knob to control just the infotainment screen. I contacted the GMC customer service #, and they confirmed that this is the way it is designed, and could not be altered or adjusted. Clarification on the date of incident and mileage above, as this has occuered since day of purchase.

I recently purchased a 2015 GMC Sierra K1500 slt. I selected the slt for the projector headlights which are not offered on the lower trims for improved lighting. However, the headlights have extremely poor illumination (cannot see off to the side of the road, very dim, poor projection in front) in low or high beam. The headlights are the worst on any vehicle that I have owned over the past 35 years. I almost hit a deer on the road at night, driving 35 mph, because the deer could not be seen in the visible arc of the low beams until too late. The deer was standing on the road fog line. I located a GM document on several truck forums concerning this issue. Original document # 4093100, pit5374 (2/27/2015) and followup document # 4109395, pit5374A (3/9/2015).

Sierra 1500 4WD 8-cyl

  • 150 miles
During night operation with the instrument cluster adjusted to proper brightness the center console lights and most notably, the intellilink screen are dangerously bright. The intellilink screen does not have an independent brightness control from the dimmer. When set to off in an attempt to mitigate the problem, the intellilink screen reactivates with subsystem adjustment, e.g. temperature adjustment, absolutely destroying night vision of the driver. If adjusting the brightness level to acceptable for the center console lighting and intellilink the instrument cluster is so dim that it requires unsafe levels of driver attention to process the dimly lit information. Dealer verified issue on two service visits but unable to correct per manufacturer. Safety complaint registered by me with GMC infotainment customer support.
