#2 of 43 New Lacrosse stalling ie going dead... any ideas ?
Jul 26, 2006 (2:22 pm)
I recently ..June 21st .leased a new Buick lacrosse. Everything fine until last week at an intersectionn. I was stopped, hit the gas and the car went dead... I mean dead. I put the car in park tried it nothing pulled the key and tried it again several times ..finally about 1 minute passed and the car started up.
That was on a Wednesday i believe. left for the weekend and the car sat for three days. When I went to start it up. same thing ..nothing. There was pleanty of battery ..all the guages and lights worked but nothing to the starter. I had it towed to the dealer who has tried for two days to replicate the scenario and cannot. GM is claiming that they do not know of any problems with the car. Anyone have any ideas? The dealer now wants me to take the car back and obviously I do not want it.

Do you have the remote start? do not take it back. Have them call the service center or whatever it is called. Get help!

No I do not have remote start...It is a really scary situation in that I am familar enough with cars to know that something like this is they cannot figure out..The service manager has been working on it for two days and aparently contacted GM tech. They say they have not heard of any problems like this.

Replace Fuse #15 (Powertrain Control Module) in the Underhood Fuse Block. On very rare occasions, the fuse is defective and/or does not make proper contact with the contacts in the fuse socket when the engine compartment heats up. Usually works fine when everything is cold.

Did replacing the fuse help? I have a 2005 LaCrosse and several times now when I put in the key and turn it to Start nothing happens. Then I try it again and it starts right up. The dealer has checked everything for a loose connection but has not been able to find anything. I think it is time to replace some components such as fuses and cranking relays. I do have remote start on my LaCrosse.

Only a guess by having read and having a different but related car...
Does your car have a battery and fuse connection box under the rear seat? Tighten all main bolts for the power and ground. Careful-remove negative first at battery. Do same for underhood power distribution.
I've read of some gremlins in cars that were fixed by doing that.
Have you tried turning key on then off. And then turning again to see if it starts on second try without actually doing crank on first try? I had problems with VATS unit on earlier leSabre not reading key when put in fast and rotated quickly to start. Security resistor code didn't get read and reported to powertrain computer quickly enough. Later cars use a key encoder rather than resistor but might be related.

They finally found the problem with my 2005 LaCrosse. The nut on stud for the starter was missing and when they tried to replace the nut the stud just kept turning. Apparently it was broken inside the starter housing. They did replace the starter and all seems fine now.We dont know if there ever was a nut on the stud or if it just came off.The cable must just have been making contact enough to crank the starter. Buick quality is not what it used to be.

I don't know who made it. It was oe and possibly made by Delco. The dealer didn't show me the old unit.
