Ignition Switch problems of the 2003 GMC Envoy



Seven problems related to ignition switch have been reported for the 2003 GMC Envoy.

car   Ignition Switch problem 1
Failure Date: 03/07/2008

The contact owns a 2003 GMC Envoy. The contact smelled gasoline, but did not pay it any attention initially. His son entered the vehicle later and also smelled the strong odor. The following day the contact filled up the tank with gasoline and the smell intensified. When he arrived home, he noticed a fuel leak by the rear driver side wheel. A mechanic stated that the leak originated from the top of the fuel tank where the fuel pump connects. The contact dropped the vehicle off at the dealer the next day and they stated that the leak originated from the gas tank, and it needed to be completely replaced. The vehicle is still at the dealer. The current and failure mileages were 59,000. Updated 04/16/08. The transmission was slipping and would not engage in 1st gear. The air condtion was blowing hot air. The ignition swithc shorted out.

car   Ignition Switch problem 2
Failure Date: 02/15/2007

On 2/15/07 I was driving to work at approximately 50mph when all of a sudden the steering went out, brakes locked up, all gauges went erratic bouncing from side to side and the heater started blowing cold air upon this happening I nearly went into a creek however struggling did manage to safely get the vehicle off the side of the road in a ditch. I had the vehicle towed to the local dealer when upon diagnosis the service manager informed me that the ignition switch had failed and all of the above components were tied into the switch. I at my own expense had the ignition replaced and the rpm gauge still does not work. I contacted GMC the very day of the incident to make them aware of this safety issue only to be bounced around to several different offices, none of which have made this safety issue a top priority. I have notated every conversation with every person that I have spoken to and what was said. I do not want to have to take the legal route, however I am prepared to do so. When ignition switches fail it should not shut down a vehicle in the manner that it does. Although I was successful at not being injured or injuring anyone else that will not always be the case in this type of failure.

car   Ignition Switch problem 3
Failure Date: 08/01/2006

The contact owns a 2003 GMC Envoy xl. The contact stated that the vehicle cranks, but will not start. The dials on all the instrument panel gauges move up and down. The dealer changed the ignition switch, but the failure recurred. The VIN was unknown. The current mileage was 74,000 and failure mileage was 34,000.

car   Ignition Switch problem 4
Failure Date: 07/05/2006

Ignition switch failure 2nd time. The vehicle will not shift out of first gear. Then you could not put the car in park.

car   Ignition Switch problem 5
Failure Date: 11/15/2005

The vehicle was in service 3 times within 14 days, gm says the problem was the ignition switch, I say the source of the problem has not been fixed. Engine stalled 6 times in moving traffic, the "abs" warning light is on, some time the "check engine soon" light comes on. Dealer replaces throttle body injection assembly. Next day the vehicle stalls again with same symptoms. Dealer replaced ignition switch again. !4 hours later engine stalls in moving traffic. Dealer installs event recording device, engine stalls and identified low ignition voltage (6. 7 vs 13. 6 vdc). Source of problem could not be identified, dealer says vehicle is safe to drive. We filed a lemon law claim.

car   Ignition Switch problem 6
Failure Date: 04/13/2005

Intermittent electrical problems caused by ignition switch failures. In April 2004 at 15,000 miles and again in April 2005 at 33,000 miles, the ignition switch on my 2003 Envoy xl failed. The symptoms in each case were abs/brake/traction lights staying on, no hvac fan, and no cruise control. The symptoms occurred once every dozen starts, and finally reached a hard fail. In each case, the dealer mechanic identified codes set for multiple systems and replaced the ignition switch. With the most recent failure, the mechanic commented that they replace quite a few of these switches.

1) sequence of events - nothing happens when we try to start. -battery voltage ok, auto-headlights on, bright - instrument panel completely dead -2 hours later, instrument on the miles per hour instrument is going wild, back and forth finally sets at zero, now engine will start.
