   Vehicle was impacted by the engine recall. After the recall repair attempt, the problem resurfaced and persists. The deal ship has the vehicle and has been down for nearly 7 weeks. I feel unsafe driving the vehicle and asked GM to write me a letter stating the vehicle is safe to drive with this recall. They refused. If this isn’t a problem, why not provide that information. They know they have a problem and won’t help.

   Vehicle passed the recall inspection and service information was updated to reflect new engine oil viscosity requirements. Now just a few months later we experienced an issue and are told the engine needs replaced as part of the L87 recall. All service and oil changes have been completed by the dealership. This fits under the EA26005 investigation into post-recall failures. Vehicle is currently at Freeman GMC awaiting a replacement engine.

   Heard a ticking sound whenever I was driving down the street then all of the sudden it got louder & SUV suddenly put itself into neutral. I was barely able to pull onto side of road to try and switch gears when hazard lights went on by themselves. Car wouldn’t turn on or start and whenever I tried again the check engine light appeared. Got the SUV towed to local, nearest GMC dealership who just called and said it was the engine failure and needed to be replaced.

Within TWO MILES of leaving the dealership, the check-engine light came right back on. The dealership initially diagnosed the problem as a lifter and wiring-harness failure. They later determined that the #7 oil-lifter solenoid had an internal short, and the wiring harness was replaced because of damage related to that…
