It only does it sometimes and it seems to fix itself but sometimes it wont start for days

at service station they plug in to check but on my end there is no response from the car

It seems as though no one has this answered. And I don't either, sorry. I have the same problem now w/ my 2007 Buick Rendezvous w/ 125,000 miles on it. I just had the transmission fluid & filter changed and it still happens occasionally. Everything seemed to go awry when I had a damaged left headlight replaced from accident. I get the no seat belt usage gong one time every 7/10ths of a mile plus then the gong sounds again for every left turn signal pulse until I use the right turn signal which extinguishes it until the 7/10ths bit starts it again. It's just aggravating from such a fine automobile(CXL). My only conclusion which "I" believe it may be is the computer. At times I mistakenly blame others. Did the dealer change out the computer because another vehicle has the gong problem? I'm frustrated as you are. Hopefully you and others can view this response. I hate buying new cars. 0730hrs 22mar2015

Hit a pot hole now car won't start.

Going in Monday for an oil change, but this web site sure makes me relax and feel better,,gas cap ? I can do that..I will just have to over tighten..amazing I just filled up and it came on...thanks everyone, you sure are wonderful angels..

In a recent collision at which point my AWD disabled light came on. Repair center says that it was triggered due to a bad calibration sensor. Since there was no damage to the outer housing unit, the insurance won't pay for the diagnostic, or the repair. Can the AWD sensor be jarred enough to go bad/blow/or whatever would cause the sensor to go bad? I also had serious damage to the front tire, wheel, and suspension from the collision. It just doesn't seem plausible that it mysteriously went bad at the exact same time and that its not related to the wreck. I appreciate any help. Thanks

the brakes release when neutral or drive selected

Fuse is fine. Replaced both the door lock system and controll unit for power windows. Still didn't work

any gear. When I do put in gear sounds like in park or neutral

Dash lights dimmed then went out. Car quit and could not turn the wheel or restart.

Dark smoke from tail pipe over heat quick

over heat after 3 minutes of driving, dark smoke comes out tail pipe

Dark smoke comes out tail pipe after 3 minutes over heat

motor completely rebuilt with three tank of gas and these two monitors and wouldn't r eset

Pressing unlock on key fob opens driver's door, but second and even third press does not open passenger doors. Is this a short in wiring or could it be a fuse?

rotated the engine forward , am move the necessary items in the front. Do I have to move wind guard between the windshield and hood?

For the past two days after I start my car the engine continues to rev with the rpm needle staying between the 2 and the 3. I turn the car off and try it again - the engine does the same thing. It will do this even if I put it in drive, move the car a little, and then put it back in park. Usually by the third time of turning it off and restarting it, the engine will idle fine. What could possibly be causing this and if it needs repair is it going to be expensive? Service engine soon light came on last night but did not come back on this morning.

ABS & AWD disabled lights are on. Scanned at oreilly and it read right front wheel speed sensor was bad. I want to verify this before I replace the sensor. Is there a procedure I can run through.

Sometimes after I drive my car and say go to the bank when I come out put my key in the ignition and it wont turn on. Its literally stuck in the ignition and I cannot turn it on or take it out..I tried to make sure my car is fully in park and it is,because I cannot move the shift at all..Anyone know what this might be and an estimated price if you can how much it may cost to fix. Does anyone know where I can take my car other than a Buick dealer to update my OnStar. I want to pay monthly but they only offer to pay by the year
