This is the worst car I have ever owned. I took impeccable care of it, yet the engine head gaskets failed starting at 70,000 miles. They would have cost almost $5,000 to fix. I decided to sell the car to mechanic who ended up replacing the engine. At 40,000 to 70,000 miles I had to replace both rear window motors, water pump, radiator, alternator, the dealer had to pull engine to fix oil leaks, two struts failed, and a host of other problems. Some repairs were covered under warranty, no wonder GM can't make a profit on it's cars. Many others are have the same problems. This is GM's flagship vehicle? No wonder people are switching to the Asians. My Infiniti has not had any problems in 70,000 miles.
The styling and power.
Design an engine that doesn't fail like it was designed in a third world country.
