Here is my issue that I've been dealing with since FEB on my 08 Yukon hybrid that I bought used this past December with about 140K miles.
Loss of brake pressure, pedal went almost to floor.
Brake warning annunciator
Stabilitrak caution annunciator
Service brakes soon message ON DIC
Stabilitrak failure message on DIC
When I say brake failure I mean the pedal goes from working just fine one minute, to going to the floor and would have a hard time stopping the vehicle if I was going 5 mph. I've learned to drive with my left foot on the emergency brake just in case since then. I've posted a lot about this on another forum, but I wanted to share my latest developments here as well.
Since then my fault has only shown itself occasionally and then only when I have been parked for a while and try to get in and go. I would have to restart the truck a few times and then I could hear the electrical pump come back to life and the brakes would work normally.
So the latest in my saga goes like this. On May 12 leaving work in the afternoon it happened again. But this time I couldn't get it to come back to life. No brakes! (Did I mention it was my birthday and I just wanted to go out to dinner with my wife?) I could hear the electric pump try to run but it would sound pretty pathetic. GOOD.... Now I can take it back to the dealership and have them troubleshoot it since it has a hard fail. I can't get it towed to the dealership (too busy at my work) until Wed the 14th. They call me back in the afternoon and tell me they have the problem troubleshot to the brake master cylinder leaking. I have seen a slight leak coming from the housing body of the cylinder. Small....I mean SMALL. Still they say it's causing air to get in the brake system and preventing the modulator from building up pressure. That will be $500 Mr. Jeff. Oops, no, that price is for the normal version not the hybrid version. That will be $1,100 Mr. Jeff. Ok, if that's going to fix my problem lets get it done. Thu the 15th... Mr. Jeff, that didn't fix the problem. We need to replace the modulator that will be $1,800 more. What about the master cylinder that was going to fix the problem? ...well it was leaking so that's going to have to stay to fix the leak. Whatever..... When can I expect the repairs to be done now? Well we have to ask GM for approval to even order the modulator. Ok do that. How long? Well it will be about 5 days unless you want to pay an "emergency fee" of $50 and then we can have it changed by Friday the 16th. Ok, in aviation we do that all the time it's called AOG (aircraft on ground). I get parts shipped overnight to me on a daily basis. Even engines, overnight!!! Should be no big deal to have my truck ready for me Friday.
Friday... Mr. Jeff, the part didn't show up today. We're sorry, we'll give you a call on Monday. Monday the 19th ... Mr. Jeff ... Whaa whaa whaa ... You get the picture. Now it's Friday the 22nd and STILL NO PART! WTF? Again, I get aircraft jet engines shipped to me overnight. Heck, I can order a set of shoelaces from amazon while I'm writing this post and have them delivered to me tomorrow, and get email updates 4 times while they are making their way here. ...but I digress. Mr. Jeff, we've got some good news today though, GM says the part should be to us by next Friday the 30th. Good lord, if I treated my aviation customers like this I would be out of a job. Perhaps I'm spoiled working in aviation. I work for millionaires, even billionaires, they expect their aircraft to take them to their next business meeting, tomorrow morning. No excuses... Maybe even get them to Washington, DC. to ask the government for a bailout, excuse me, can I please borrow 360 million? I promise to pay you back next week? You..., yes you.... The one reading this post. No? (Clearing throat) Alright then, moving on...
Now the good part of this is, even though I didn't buy my used Yukon from the dealership, (I bought it from a ford dealer, what was I thinking?) they comped me a loaner car while mine is in the shop. So HOPEFULLY next Friday I can plunk down my $3,000 and get a working (more importantly, stopping) hybrid. Which my work buddies have affectionately nicknamed "The Flaming Hybrid of Death".
