One problem related to car will not start has been reported for the 2001 GMC Jimmy. The most recently reported issues are listed below.
I purchased our 2001 Jimmy on 2/05/01 (new). We experienced the first of 7 electrical system failures on 10/12/01. On 10/12/01 the brake light switch failed and was replaced. On each of the three following dates; 7/26/02, 6/18/03 and 7/02/03 the ignition switch was replaced after the vehicle failed to start or stopped running during operation. It was towed to a GMC dealer on each of those occasions. On 8/08/03 the vehicle again would not start and was towed to the dealer. We were told the problem this time was the battery. On 8/23/03 the fuse block was replaced after the vehicle stopped running during operation. Again towed to a dealer. Again on 10/10/03 the fuse block was replaced after the vehicle stopped running during operation. Again towed to a dealer.
