The contact owns 2004 Pontiac Grand Prix. The contact heard a clicking noise underneath the vehicle while driving 15 mph. The clicking was heard whenever the contact was making a left or right turn. The contact took the vehicle to a local mechanic who noticed the frame was cracked and informed the contact about a NHTSA campaign number 04V299000 (structure:frame and members). The contact called the manufacturer regarding the recall and the manufacturer stated due to the VIN the vehicle was not a part of the recall. The contact stated the clicking noise had become louder and more consistent. The contact made an appointment to take the vehicle the dealer. The failure was 130,000.

Heads up display on 2004 Grand Prix failed due to control spring becoming free due to premature part failure of the plastic arm. This leave a blackish/grayish square on the windshield where creates a driving nuisance- where the hud should be. This part failure is mentioned numerous times on the internet, thus leaving the owners with a $600-700 repair in which there isn't a new part but instead a rebuilt one put in.

The front and back floor on the passenger side stays wet all the time. We have been unable to find out where exactly it is coming from. When it rains it will puddle even worse. The carpet is getting so wet that it is going to rotten if the problem is not solved.

The contact owns a 2004 Pontiac Grand Prix. Whenever there is a change of force or motion (reverse, stopping, shifting), the contact hears a "click, click, slam" noise. It is similar to a shift in the frame or suspension. He also stated that it sounds as if there are loose bolts. The dealer found that the bolts that hold the engine to the frame needed to be replaced. His VIN was not included in NHTSA campaign id number 04V299000 (structure:frame and members), although the failures were identical. The failure mileage was 50,000 and current mileage was 72,000.

Same as another person that reported this recently. I have a pool of water in both the front and rear passenger areas after heavy rains. I'm taking the vehicle into the body shop tomorrow, but it also appears to be the plastic piece coming away from the bottom of the windshield, and as the previous person that reported this also stated, the guy at our body shop said he's seen this with Grand Prix's also.

- Sleepy Hollow, IL, USA

Huge pool of water on the passenger side floor, in both the front and back. The shop-vac cannot get it all up. Cause looks to be black hard plastic molding at the base of the windshield has lifted away from the windshield. Heavy rains in the last few days has lead to this discovery. Local GM dealer has said they have seen this before. Have advised me not to drive the car until they can see it - that's in two days.

2004 Pontiac Grand Prix gtp. 45,000 miles. As of today, I have had this vehicle in service eight times for steering-related defects, beginning two weeks from the date of new purchase in January, 2004. Three different dealers have all told me "it's a design defect...there will be a fix soon". replaced rack and pinion twice, middle steering shaft twice, and rack/pinion and engine cradle bolts spontaneously work loose every 3,000-5,000 miles. Now vehicle is out of warranty. Most recent visit to century Pontiac in tampa, they attempted to charge me $75 in order to apply yet another tsb regarding loose steering, steering wheel bind, etc. I had to call Pontiac and complain bitterly, they then waived the fee...but did not pay for the rental car. Thus far, power steering pump has failed and been replaced, A/C compressor has failed and been replaced, middle steering shaft replaced twice, entire steering column replaced twice, and there is still a persistent "jolt" through the steering wheel whenever putting car into gear, or turning steering wheel to right, going over a gutter, etc. Also, loud "clunk" resulting in severe shudder in front of vehicle. Dealer(s) state there is no fix. Have nearly lost control of vehicle three times due to steering suddenly loosening, or binding, wandering off-center, etc. Dealer says there's nothing more they can do. When is NHTSA going to listen to all the complaints regarding the steering issues on this vehicle and launch an investigation"? steering rack bolts coming loose? engine cradle bolts coming loose? steering shaft failures and fractures" every time the vehicle is taken to service, the dealers and service managers "play dumb" and try to say "I don't hear anything"...or "it drives like all the other Grand Prix's". please don't let GM and Pontiac continue to insult our collective intelligence and ignore these steering and design issues to the point where someone gets killed.

2004 Pontiac Grand Prix - water leakage in the front passenger floorboard via the air/heat fan belt area. Soaking entire front passenger side floorboard. I have contacted two different local Pontiac dealerships who informed me that they have both seen several 04 Grand Prix models come into their dealerships with this problem. They said that it was possibly one of two things. A problem with the deflector for the fresh air vent by the cowel or it could be the water hose leading from the sun roof that could be clogged. The fact that water is leaking into the interior of the car in the are where the water is collecting could cause a serious electrical short, as the area that the water is coming through the electrical components of the vehicle. I view this is as a default in the design of the vehicle and would like someone to look into this matter. I am afraid that left unattended to that this could cause a fire. Both dealerships have indicted that because my vehicle is not covered under warranty that this matter would take several hours to correct and estimated a cost of approximately $230 to correct this matter.

Vehicle had a design flaw in the instrument panel clear plastic cover. In daylight there is a bright semi circular reflection in each corner. The sun glares directly off the plastic into the driver's eyes causing a sudden distraction.

We just purchased 2004 Pontiac Grand Prix GT 2 has a horrible semi-circular mirror like reflection from each lower corner of the instrument panel right into our eyes making it difficult to handle the vehicle. It occurs from 11am to 2 pm from the overhead sun.

When I go over bumps in the road or turn the wheel the veh makes a clunking/knocking sound in the floor and sometimes when I turn the wheel (parked or moving) there is a similar, clanking sound near the wheels. I have taken the veh to the dealership to be check several times. The first few times they tore it down and tightened things. The last time they said they contacted Pontiac and was informed this was happening on several vehs and do not have a fix.
