I've been having issues with the whole Stabiltrak issue and brake service light coming on so I took it in to the dealer for service. I have an 08 Outlook XR with 53k miles. I had purchased the Mastertech warranty and the dealer said that the reason the light is coming on is because of a leaky master cylinder. Which apparently is very common because the service guy knew about it prior to the diagnosis. He called and said a new master cylinder and brake booster would be covered under the extended warranty but the brake fluid/brake flush/brake bleeding is NOT!! It is gonna cost $177 to have it flushed and bled. How can a warranty cover the parts and labor but not the full job? Any help on how to handle it is appreciated. I'd rather not pay anything other than my deductible but I'm kinda stuck. I guess thy always find a way to sick it to you!!!

Ive seen about 2 other post on the Acadia forum- of leaks.
Usually the fluid is lost.. but no visible trace.
Turns out its leaking inside the booster or something like that.
Maybe this warranty doesnt cover the fluids?
But I dont know of the GMPP would too?

Many aftermarket extended warranties do not provide near the coverage a GM extended warranty does. That is one reason they are usually less expensive. Read your policy and see if it says anything about fluids, seals, etc being covered if they are a part of the repair/replacement of a defective part.

Bleeding the brake system, flushing, and adding new fluid should be a normal part of the replacement of the components. Not much you can do if your policy says otherwise.

I found their info on the web but they say to refer to the policy for exact coverage. I'm also not sure which policy you purchased.

Re: Stabilitrak/ bad master cylinder/ headlight!!!!

I have the Mastertech Utra-wrap warranty and other than my deductible being $100, it did it's job. The dealer diagnosed the Stabilitak issue as having DTC C0267-low fluid level and said it was leaking inside the booster.They replaced the booster, MC, brake fluid under the warranty. I also had some other work done that I'm not happy with at all. There is/was oil leaking form the front crank seal portion of the engine. That was covered under GM's powertrain warranty and replaced. They also put new oil in the engine but didn't change the filter. Really???, I would have gladly paid $5 for a new one. I believe there is/was still an oil leak from that area because the "Tech" at GM didn't bother wiping or cleaning all the oil that was leaked in the first place. Also, I was losing coolant and requested they check it out, they said they couldn't find an issue, but after getting the car back and looking under the hood I can see a trail of orange coolant dripping from above the crank pulley, water pump?? Had the headlight recall done and according to the paperwork they replaced the connectors only, GM 20968489. I thought it was a harness recall, not a bulb connector recall? The air box wasn't put back together correctly and the passenger side headlight bulb cover is lying on the inside wheelwell, not happy with the work and will be taking the car back on Monday. Sorry, for the bitch fest, but I used to be a mechanic and took pride in my work and making sure the customer was completely satisfied.

Yes, it is the water pump leaking. It's covered under the GM Powertrain warranty. GM just updated the replacement procedure - new bolts must be used and tightened according to the Service Bulletin. Information available here:

I apologize you have had such a negative experience with the dealership. Please, let me know how your visit goes tomorrow.

Just thought I'd add this to the list, 2008 Outlook XR, 80,000 miles, with intermittent then solid Stabilitrak & red Brake warning light, finally noticed that the Fill Level for this master cylinder is halfway up the filler neck, added a pint of DOT3 fluid, fixed all the complaints.
No idea why the Low Brake Fluid sets Stabilitrak & Brake System Alarm, but not ABS, been chasing possible Stabilitrak faults that also affect a previous problem with low speed GMLAN ground fault.
Anyway, pull the vacuum sensor off the bottom of the Brake Booster, and about a pint of dirty brake fluid comes out, first time in 50 years of car repairs, with all over 150,000 miles on them, the booster sucks the brake fluid out of the master cylinder.
I see a few other complaints like this on the website, just thought I'd add it to the list.

 

[rbarrios]

yeah-- some of the fluid will leak into the master cylinder..
most will not notice any leak-- since it leaks internally..

this was just being discussed on one of the other forums-- I think Enclave.

I had the same issue with my Outlook and was stuck with a partial bill just the same as you and Im sure many others. also have a headlight wiring harness issue that has become recurrent.

I actually had to fight with our dealership to get them to cover the replacement of the master cylinder/brake booster as they didn't believe me (original post: topic=2337.0). They wound up covering the repairs and replacing the pads/rotors for free...so i would talk to the dealership and see if they can work with you. --just my 2 cents....cheers

I had this exact issue with my 2008 Outlook. My dealer said they couldn't help me due to no recall even though it is a known problem. I called GM and got the run around speaking to four different "customer service experts" over a few week period. They finally said they could not do anything for me. There needs to be a recall for this issue. Everyone with this problem should report to NTSB. This is obviously a design flaw.
