The alternator ripped out of the engine block. This resulted in the vehicle stalling on 3 separate occasions. When this occurred the vehicle lost power steering and brakes, which almost caused an accident. Mechanic indicated that he had never seen anything like this before, and didn't know what could have caused it.

Problem seems to be getting worse. Dealer is unsympathitac towards this problem. Dealers and repair shops are inconsistent in their diagnoses of the problem. GM refuses to acknowledge that a severe problem exists until someone becomes injured or gets killed becaue of it. The NHTSA has opened an investigation into this persistent problem and GM still is unphased an apethetic towards the plight of the consumer. No safety defect listed.

The headlights filcker at various times and this alternator has been replaced 3 times. The dealer has done all that they can, but the alternator failure is a design flaw with the 3.5L engine. I have been told that this is not a major problem, but the 'flickering' has become more regular and seems to happens for a longer duratation. I look forward to a solution from GM on this.

When driving at night with headlights on, without any warning headlights will completely shut down, causing poor visibiity for driver. Dealer has not been able to determine cause. Intermittently, the head lamps flicker and shut off. Alternator failed. Alternator was replaced twice, once because it was charging 14.2 volts. Left rear tire cupped badly, causing noise, no specific tire information given.

The major complaint I have with this automobile is the electrical system. The lights constantly flare and flicker as if they are shorting out. GM has claimed that there was a problem with the alternator and after a substantial wait for a remedy that being a redisigned alternator GM still has not fixed the problem. The lights have flickered on and off since the auto was purchased. The mechanics at my dealership have tried but failed to find the problem. The alternator has been replaced twice one by the dealer in desperation and again when the newly redesigned from GM arrived after nearly 6 months from the original promise of a fix came in.my greatest fear is that the computer in this car will fail with all the power surges being put through the electrical sytem. In my opinion this has manifested itself already with the need to reprogram the computer in this car. As this auto was purchased new I would have thought I was purchasing a vehicle free from defects. I hope that this vehicle doesn't turn into a money pit. Thank goodness these problems began while under warranty hopefully GM will continue to honor the warranty after it expires.

All interior and exterior lights will spontaneously dim. Dealer has replaced alternator, and inspected electrical system, and could not find cause. Problem still occurs. Dealer is ordering another alternator.
