3 months ago, I bought a used 2004 Pontiac Aztek with 37,000 miles. The dealership said that there is no problem with the car and it passed their 60-point inspection. At 39,880 miles, it blew a head gasket, has transmission issues and starting problems. It is now at Hennessy Pontiac service center - 7261 Jonesboro Rd. Morrow, GA 30260 (770-968-6800) to be fixed. They quoted $2,300 to fix the head gasket. Then they told me because the car is just out of warranty, they would fix it if I were to pay $1,100 to do all the 30,000 miles maintenance (change all the fluids - trans, coolant, power steering, brake and fuel injector cleaning). All these fluids had been changed 3,000 miles ago by Southtowne Hyundai. Checking with other repair shops, I got an average quote of $1,000 to repair the head gasket.

I believe the practice of changing all the fluids on used cars before a sale is finalized is a plot to disguise the true condition of the car. Ironically, the first piece of paper I got to sign was the "as-is" statement. Upon research on the internet, I have come across a number of complaints about the Aztek head gasket, trans, A/C and wheel hub issues along with problems relating to the Dex-Cool coolant used in GM cars.
