problem #1

Oct 042020

Sierra 1500 SLE V8

  • Automatic transmission
  • 35,676 miles

While driving on the highway our vehicle steered itself left into on-coming traffic lane (fortunately for us there was no vehicle coming toward us at the time) and all steering ability was lost momentarily and then steering engaged and we were able to pull back into our lane and off to the shoulder. We could have been killed or killed someone if a vehicle had been in the oncoming lane.

We're very sorry to hear about what you've been running into, We then had truck lifted by CAA to dealer's lot for explanation and repair. The dealer said it was loss of power and replaced battery cable. We are now fearful to drive this vehicle as we believe this could happen again at any time. No warning at all before it steered left. This is a serious problem. We do not trust fix and feel it will happen again.
