I recently purchased a 2007 Chevy Uplander with the 3.9 liter engine and it started leaking coolant at 57k miles. It was the cross over pipe gasket. Apparently this gasket and the head gasket are common problems with GM's 3.5 and 3.9 liter engines. My vehicle also had the head gaskets replaced at about 50k miles, just before I had purchased it. GM has a TSB about these problems which explain what the dealer should do to fix the problems. You may be able to google it to find out more about it. It sounds like your dealer is just doing a lousy job fixing it. I assume you have the 5 year or 100k mile powertrain warranty; the next time it fails I suggest you try another dealer. Good luck.

My 08 Impala SS, has a clicking noise in the dash, kind of behind the radio, the noise starts when you unlock the doors with the remote, it can also start when just opening the door, or even just starting the engine with the remote start, the noise stops after about 45 seconds or so, then returns again about 45 seconds after shutting off the engine. and again lasts another 45 seconds or so. The car has just under 48,000 mi. on it

I would try another dealer. This one does not deserve your business. Good luck.

Question - I just had my car in today (11-12-12)...leaking cross over pipe . they ordered a new and improved pipe , etc. to fix. Did they use the new improved pipe or is this lip service??? Did they change the pipe each time or patch with a gasket... my warrenty is expiring in 3 months... Got to figure weather to keep or dump??? Thanks for any info you can give..

I own a 2007 Uplander with the 3900 V6. The head gasket and crossover pipe gasket failed at about 55k miles and was repaired under GM's powertrain warranty by the dealership where I had bought the vehicle. I felt reassured when I bought the vehicle, knowing these repairs were already done. Unfortunately, at 65k miles the gaskets started leaking again. The dealership should have sent the cylinder head out to a machine shop to get it back to spec because it was warped. I found this out when it was repaired again by another dealership closer to where I live. The second dealership had the cylinder head machined. It's been 17k miles since the second repair and the leaks have not returned (knock on wood). The key to these repairs is making sure the cylinder head is within spec so the surfaces are smooth for the new gaskets to seal properly. If the dealership does the work properly, then it should not leak. Within the exception of these gasket issues, the 3500 and 3900 V6 engines are good and reliable engines. I have got 82k on mine and I expect at least 150k without any major problems. If you check out the Uplander forums there is a blog titled the 250,000 mile club and some individuals have made it well past 150k miles without major problems. Good luck.

I have an 08 Chevy Impala and when the car is in park, I hear a lot of sloshing water and the heat turns to cold. Feels like the A/C is on. I have been hearing the sloshing noise for a while but I have only noticed recently that the heat is cold when the car is in idle or parked. A few months back, I had a warning light flash on the dash saying Engine hot...A/C automatically shut off and my temp gauge went cold (wasn't reading). The message went away the next morning on the way to work and the gauge was working just fine. After that I started smelling antifreeze as if there was a leak or the car was running hot. No leak and the car hasn't run hot.

#107 of 118 08 impala Brake pedal position sensor
Dec 17, 2012 (8:53 am)
first off my key would not turn off all the way, found the problem on the right side of the gear shifter and fixed the wire all good again, a week ago today the car would not come out of park nor would my key turn off all the way. so i have re wired the plug and bought a new shifter for the car, none of that has worked, i was told today it maybe the brake pedal position sensor. Can someone help me out on this matter? really getting frustrated as chevrolet dealerships keep telling me they are 99.9% sure this part will fix it! well each time i am in that. 1% of the part that doesnt work.
