Differential Unit problems of the 2013 Chevrolet Tahoe

This vehicle was purchased from mac haik Chevrolet in houston, TX. Only one key was provided during the vehicle purchase. The other key was promised in an "we owe you" statement, but never received. At some point in time, it is believed the 2nd key was used to access this vehicle at undisclosed location(s) and or time(s) in addition to onstar app access. The vehicle began to make rubbing sounds when turning corners and losing a little power. In July 2014, I noticed my vehicle seemed to shake when going over speed bumps in a manner inconsistent with the way it normally went over speed bumps most times after vehicle delivery. In addition to, the engine seemed to be idling too high at no speed and in a manner inconsistent with the way it performed most times after vehicle delivery. Also, the dashboard is cracked around the airbag. In August 2014, I went back to the dealer for inspection of these problems. I was informed repairs were made to the front differential of the vehicle and the transmission was overfilled. I was provided a statement of the work, but I felt the verbal explanation for the work was too vague being my vehicle was in the shop for approx. 2 weeks. . Read more...
