Anti-theft Controller Problems of Chevrolet Equinox

The contact owns a 2011 Chevrolet Equinox. The contact stated that while driving approximately 30 mph, the headlights failed and powered back on independently without warning. Additionally, the windshield wipers and the anti-theft device independently powered on without warning. The service tire pressure monitor warning light was also illuminated. The vehicle was taken to the dealer for diagnostic testing. The technician advised that the body control module needed to be replaced. The manufacturer was made aware of the failure and advised that the vehicle was not included in any recalls. The vehicle was repaired. The approximate failure and current mileage was 48,000.

(1) on or about 10/27/06, alarm system deactivated itself, interior and exterior lights turned on, doors remained locked. (2) on 11/01/06, alarm system activated itself, doors locked themselves. (3) on 11/27/06, vehicle shuttered and went into 'limp' mode which may have caused damage to the transmission. Onstar and dealer retrieved the following error codes: (I) p1626 - theft deterrent fuel enable signal lost, (ii) c0276 - traction control not allowed (tcm / abs), (iii) u0100 - lost communications with transmission control module (tcm), (iv) u2105 - lost communication with engine control module (ecm). Between 11/27/06 and 12/21/06, dealer supposedly replaced bcm three times and 3rd new bcm fixed problem. Each new bcm would go to zero (0) and the mileage could not be programmed. During that time the theft deterrent system was deactivated which was unknown to me. Current mileage is incorrect. I believe that the original faulty bcm may have been re-installed and the codes cleared when they were unable to fix the problem. I do not believe that the other none-bcm error codes have been addressed but the dealer forced me to take my vehicle home on 12/21/06.
