general problems of the 2017 GMC Yukon

Stabilitrak warning light comes on intermittently. Cruise or anti-lock brakes do not work when this condition is present.

My vehicle began shuddering during acceleration and would violently jerk forward after gas pedal was engaged with decreased power in forward acceleration and increase in rpm. This last a couple of weeks. Now, my vehicle is completely broke down and at a gm certified service center. The service manager states torque converter completely went out and the transmission is burnt up. The mileage is at $61,000, so gm warranty won’t cover it and the company that holds the extended warranty I purchased hasn’t been able to be successfully contacted. There is a “service” bulletin but no recalls and a class action lawsuit (that I’m not a part of) but no recall. My vehicle completely lost power going 50mph on a busy road without warning. This needs to be a recall due to this dangerous circumstance.

The information screen on the gauge cluster sometimes will stop working. This is dangerous as it is the only part that shows if the vehicle is in park, reverse, nuetral, or drive. It also is the only part that shows the vehicles fuel level, blinker, cruise control, temperature and other warnings and controls. This is a common problem for the 2015- xxxx Yukon and tahoe.

The vehicle started to pull all the way to the right side while driving on the 710 freeway in long beach, a noise started to be audibly heard while I was driving. I I contacted the executive offices of general motors and nobody could assist me with the repairing this vehicle. I was told there is no remedy for this issue.

Adaptive cruise control system is not properly designed to recognize vehicles that are adjacent to the traveling lane and not directly in front of the vehicle. When traveling on the interstate with adaptive cruise engaged, we came around a bend in the road approaching an entrance ramp. There was a slow moving vehicle on the entrance ramp which was apparently identified by the adaptive cruise system as being in front of our vehicle in the same lane. The adaptive cruise caused our vehicle to brake violently while still in the bend in the road, which in turn caused us to swerve into the next lane where there was a car traveling adjacent, but just behind us. This was a very unexpected series of events, and could have resulted in catastrophic consequences had the adjacent car been any closer at the time. This is a major flaw in the adaptive cruise system. And it is compounded by the fact that the adaptive cruise system cannot be switched over to a manually controlled more traditional cruise system. This is a severe design flaw with the GMC Yukon. Some of this could be remedied by issuing a firmware update that allows the driver to disengage the adaptive cruise and switch to a more traditional cruise control method. But GMC has no interest in providing this update, even with multiple message board threads talking about the dangers of the adaptive cruise control.

While driving at various speeds, the vehicle dash displayed numerous and random error messages: (wording may not be exact) service front collision system. Front radar blocked. Front collision system unavailable. These messages indicated a problem with the forward collision avoidance system. The weather on the particular day varied. Errors occurred at various speeds. This hazard can cause serious harm if the sensors detect an imminent forward crash in error and apply the brakes in traffic. This dangerous situation is likely to result in serious personal injury or death. The root cause was determined to be related to an additional failure mode identified in the oily substance leaking from the control box mounted on the front windshield. This oily substance was identified by the vehicle owner and reported to the dealer.
