Replying to: dumpster (Apr 14, 2007 8:08 pm) my 99 grand prix GT caught fire while i was driving on May 25 2007 my car filled up with smoke and none of the doors unlocked and none of the windows went down. GM needs to do something before somebody loses their life! Replies to this message: tommy231 (Jun 10, 2007 2:32 pm) 05toering (Jul 05, 2007 7:36 pm)

Replying to: racedriver11 (Jun 10, 2007 11:55 am) There is an open investigation in-progress with GM and NHTSA for 1999 through 2002 GTPs with the L67 3800 Supercharged Engine for underhood fires (http://tinyurl.com/3cljhx). These fires seem to start 5 to 15 minutes after shutting off the engine. There was an investigation for non-supercharged engines, but it is closed (http://tinyurl.com/29239v).

Replying to: tommy231 (Jun 06, 2007 9:39 pm) I looked at 2 other GTPs yesterday; a 1999 and another 2002. The 2002 had the same configuration as mine with the two wires coming off of the starter solenoid. However, neither wire was stuck to the solenoid, but they were both wedged under the positive battery cable such that a similar concern exists due to the pinching of the wires.   The 1999 did not seem to have the 2 wires, or if it did they were routed differently. The engine was too warm to look closer at the time. The 1999 seemed to also have different heat shielding surrounding the fuel lines above the steering wheel area.

Replying to: tommy231 (Jun 10, 2007 2:32 pm) Looks like the NHTSA investigation has been upgraded to an Engineering Analysis as of June 12th (EA07-008) and the other GM supercharged models have been included. They should include the 97 and 98 GTPs as well since those are identical, IMO. The lead investigator said he would consider those years but didn't have enough official complaints w/the NHTSA on file for those years.

I recieved a message from th NHTSA that the investigation for GTs was closed but it only was upto 1997. what about those of us with newer models (1998 and up) that this has happened to. It is the same engine as the supercharged GP. please let me know if anyone has contated GM about this. I am more than willing to put together a class action lawsuit against GM

Replying to: tommy231 (Jun 06, 2007 6:38 pm) Please contact me regarding the investigation. I did send some picures to someone awhile back. If this is you, please let me know where the investigation stands. Thank you.   Kind Regards,   Julie Haugland julierotarysystems.com Replies to this message: tommy231 (Jul 11, 2007 5:40 pm)

Replying to: tommy231 (Mar 04, 2007 9:22 pm) My wifes 1997 Grand prix caught on fire about year ago. The 3800 caught on fire right under the coil pack. My insurance fixed it but the dealer never said why it happened. The fire was put out rather quickly so it didn't do much damage($1200.)She was driving it right before it happened and it was running fine. She stopped and a few minutes later it was on fire. Haven't had any problems with it since. Replies to this message: tommy231 (Jul 11, 2007 5:42 pm)

Replying to: juliehaugland (Jul 06, 2007 10:10 am) Hello Julie,   I forwarded your contact information to GM. I presume from your note that they didn't contact you. My hope was, and still is, to find a vehicle that was caught early enough for them to get a better idea what the cause is. As you can imagine, it is nearly impossible to positively root-cause a fire when the vehicle is a total loss. Since your vehicle is not available for inspection, I don't think there was much they could do with your contact information. So I guess that just means you are one of the 180 names they have on file with this issue.   NHTSA has closed their Preliminary Evaluation (PE07006) on GTP under-hood fires and has opened an Engineering Analysis (EA07008) on a wider range of GM vehicles. Non-supercharged engines are not part of the new effort either, as the investigation of those vehicles (EA02030) remains closed. Here is a link to the PDF that describes the new NHTSA initiative: http://tinyurl.com/yo8jnf   According to EA07008, they still don't know the cause. However, the response given to NHTSA from GM, http://tinyurl.com/3832xa, had all the content eradicated, presumably for confidentiality reasons, so it is difficult to know the whole story. The good news is that many of these so-called Preliminary Evaluations, like PE07006, never advance to the Engineering Analysis level, so we are one step closer to a root-cause and a possible recall. If the subject vehicles are ever recalled for this issue, I am not sure what your available legal actions might be as I am sure you'll need to consult an Attorney for that advice.   My personal investigation into this hasn't gone very far either. I posted one possible cause and my proposed fix for it. However, I doubt that this is the only cause, or the main cause, as some of the qualified vehicles I looked at were wired differently than mine and were therefore exempt from my concern. This weekend I plan to change my fuel injector o-rings as yet another precautionary measure.

Replying to: reek (Jul 11, 2007 8:05 am) Hello Reek,   Is yours supercharged? If not then it is not part of any open investigation I am aware of (see #69 above). If it is, then it was a perfect candidate for root-cause analysis.
