Service All Wheel Drive System/Service Real Wheel Drive
 

I bought my Buick Lacrosse new in April 2011 and have about 58,500 miles on it, I know, very low miles, I used to work from home a lot.

I have had all scheduled maintenance done and just recently had a service alert pop up that says, "service all wheel drive system and then service rear axle. I did get new Goodyear tires about 6 weeks ago.

It stopped happening after 3 or 4 mornings of this alert.

Has anyone had this happen? I do live in a cold weather state.

I don't want to cause a bigger problem but I don't want to get ripped off because I had to fire the dealership where I bought the car and had all service done when they charged me over $300 for a new battery when THEY broke the cables which were fine prior to the new battery!

Please offer your advice asap because I am supposed to take Beauty the Buick in this week to another dealership.

Thank you!

Well unfortunately this turned out to be a very costly issue. The warning light came back on and I drove the car right to the dealership with it on so they could accurately diagnose the problem. Turns out it was a failed rear
clutch piston that was leaking fluid into the differential. Required a replacement rear clutch piston kit and to do this required that the rear axle had to be removed and reinstalled. Approximately 7 hours of labor! $1473.99 including tax!

Apparently this is common in Cadillacs but not so common in Buicks.

I still love my car and am happy to have her back home and running smoothly.

Thanks Rich for your thoughts.

I think I will see if the message comes up again because I was unable to find anything in the manual.
