Three problems related to electrical system have been reported for the 2007 GMC Sierra. The most recently reported issues are listed below.
Engine shuts down, "service brake system" message appears in display, abs light illuminates. Since engine shuts down, lose steering and braking. Latest incident occured on highway during rush hour. This also happened first year I owned the vehicle (I bought it new), they replaced the underhood fuse box. This happened again on March 13. They replaced a blown pcm fuse and said they could find nothing wrong. When it occured on 3/29, I replaced the fuse 5 times to try and get off the freeway. After each time it was replaced, I could drive 1-2 miles before it would blow again.
Vihicle would not start, ignition would not work and air bags!!!.
Our customer/insured was driving his 2007 GMC Sierra on April 23, 2009 with his child in the back seat, the auto started on fire as he was driving. He was able to get out of the auto with the child before fire reached the interior. The fire started in the engine compartment and traveled throughout the rest of the auto before the fire department could get to the scene. Over 3/4 of the auto was totally burned.
