My 2004 Pontiac Grand Prix gtp comp G has unstable headlights. When driving, they "bounce" and it is really distracting to me as well as other drivers. I belong to a Grand Prix car club and a member with the same car as mine experiences the same problems. A fix and a recall is needed asap. The constant vibration of the headlights is very distracting and will eventually start causing problems for drivers. In addition to the above complaint, I have another. I have found a total of 3 recalls on my vehicle yet I have never received notification from Pontiac nor my dealership. I would like to have peace of mind that if something is recalled on my vehicle that the manufacturer is taking steps to correct it asap. Instead, I am finding out this information on the internet and will need to take steps to ensure my car is safe.

All 2204 model year Pontiac Grand Prix's exhibited unusual and excessive headlight 'bouncing'. there are many other reported complaints on this site. A model year running change was made to the 05 Grand Prix's which effected a permanent fix. There is supposed to be a tsb issued for prior 05's and all 04's but this bulletin has not yet been released. This is a real problem that needs to be addressed and resolved. I would argue it's a safety issue meriting a recall.

The headlights shake on the 2004 Grand Prix as a result of insecure mounting. The dealer said there is nothing they can do, the headlights are installed as designed. I also contacted Pontiac via E-mail, their reply was that this a normal characteristic of the car. I do not believe this is a normal characteristic of any car and is a grave distraction to the driver as well as oncoming traffic!.

Headlamps shake badly even on a smooth road. This makes it very difficult to see when driving at night. It is not only annoying and distracting to myself and other vehicles on the road, but is also a safety concern. Dealer has told me that a fix is not available until December, and right now it is August.

There has not been a failure per SE, but it is poor engineering, I own a 2004 Pontiac Grand Prix and have noticed that the headlights shake on hitting bumps, I would imagine that it is distracting to other traffic. I have been told that there was nothing offered from GM to help this condition.

The headlights "bounce" on our 2004 Grand Prix due to insecure mounting. This can be seen after dark and must be very annoying to other drivers, some who respond by flashing their brights. This may be a more prevelent in the gtp/comp G model which has a stiffer spring and strut combination. At this time, there is no repair available.

Bouncing headlights. Slight bumps or unevenness of road surface result in obvious headlight flutter; visible on road signs, the glare off the car in front, reflectors, etc. Causes distraction to driver and other motorosts. Dealer says this is normal for this vehicle. Pontiac should provide a solid fix free of charge.
