2006 GMC YUKON Electrical System Problems

This is the 2nd GMC Yukon with a faulty drivetrain I've acquired in 3 years. Both occasions were directly after the vehicle had professional service done related to the faulty system. The transmissions was fully serviced at reputable repair shops and within a month or 2, without warning, the transmissions started having mechanical issues without DTC being triggered. As well as a 2004 Buick Rendezvous with less than 70k miles on it. The 2001 GMC Yukon suddenly lost reverse and park while driving and imploded the transmission in the process. The 2004 Buick Rendezvous started slipping and ceased to move by it's own power when at operating temperature. The 2006 GMC Yukon Denali stopped shifting gears while on the freeway at 55 mph and systematically lost all moving gears within a day also while at operating temperature.

TL* THE CONTACT OWNS A 2006 GMC YUKON. THE CONTACT STATED THAT THE AIR CONDITIONER IN THE FRONT OF THE VEHICLE WAS NOT OPERABLE. THE VEHICLE WOULD NOT POWER OFF EVEN WHEN SHIFTED IN THE OFF POSITION. THE VEHICLE'S BATTERY MUST BE DISCONNECTED TO POWER OFF THE VEHICLE. THE CONTACT STATED THAT THE FAILURES WERE INTERMITTENT. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE BLOWER MOTOR WAS DEFECTIVE AND NEEDED TO BE REPLACED. AN ATTEMPT TO REPAIR THE VEHICLE WAS MADE; HOWEVER, THE TECHNICIAN INFORMED THE CONTACT THAT THE BLOWER MOTOR HAD BEEN DISCONTINUED AND THAT THERE WAS AN UPDATED MODEL. THE GOOD CHEVROLET DEALER INFORMED THE CONTACT THAT THE VEHICLE WAS NOT INCLUDED IN THE SPECIAL COVERAGE ADJUSTMENT FOR THE HVAC. THE MANUFACTURER STATED THAT THE VIN WAS NOT INCLUDED IN THE SPECIAL COVERAGE ADJUSTMENT AND REFERRED TO CONTACT TO NHTSA. THE FAILURE MILEAGE WAS...

OIL SENDING UNIT... REPLACED 3 TIMES SINCE I'VE OWNED THE TRUCK.

THE REAR LIFTGATE WILL NOT UNLOCK OR OPEN & REAR LIFTGATE WINDOW WILL NOT UNLOCK OR OPEN. THIS IS A SIGNIFICANT SAFETY HAZARD FOR PERSONS TRAVELING IN VEHICLE, AS THERE WOULD NOT BE ANY MEANS TO EXIT THE REAR OF THE VEHICLE VIA THE REAR LIFTGATE OR REAR LIFTGATE WINDOW IN AN EMERGENCY (ESPECIALLY FOR MY CHILDREN WHO SIT IN THE 3RD ROW OF SEATS) ALL 4 STANDARD DOORS STILL LOCK/UNLOCK BOTH MANUALLY AND WITH THE REMOTE CLICKER, HOWEVER, THE REAR LIFTGATE NO LONGER UNLOCKS OR OPENS MANUALLY OR WITH THE REMOTE CLICKER. THIS DESIGN DEFECT OF THE REAR LIFTGATE AND REAR LIFTGATE WINDOW ON THE GMC YUKON IS A SERIOUS HAZARD TO THE SAFETY OF PASSENGERS. NOW THAT THE REAR LIFTGATE AND REAR LIFTGATE WINDOW IS "FROZEN" IN THE LOCKED POSITION, THERE WOULD BE NO WAY TO EXIT THE INTERIOR OF THE VEHICLE FROM THE REAR LIFTGATE OR REAR...
