I purchased a new GX470 about 6 weeks ago and it has been riddled with problems. Currently the vehicle has been at the dealership for over a week and they have told me they have called a Lexus rep in to diagnose the cause of the problems. Has anyone else experienced this kind of trouble with a GX470? The vehicle only has 2,000 miles on it. I am ready to give it back to Lexus! Any suggestions?
Problems
1. Air compressor turns off when idling for a while at a red light. Dealership said Lexus just discovered this problem, but does not have a fix yet.
2. Audio system (Navigation with Mark Levinsion) works periodically. Most of the time the system will not come on, intensely loud electrical sounds come from the speakers. This even happens when the system is turned off! Dealership says they don't know what the problem is.
3. After the vehicle stops, the transmission has a delayed shift (or thump sound). Dealership thinks this is normal.
4. The driver's side outside mirror vibrates so bad at 65mph, you can’t see traffic.
5. When the audio system worked, the tweeter in the driver's door vibrates.
