2010 LaCrosse CXS Electrical Problems - My car is dead.
I bought a 2010 Buick LaCrosse CXS AWD just over a month ago, and have been LOVING it. Beautiful car, great ride, best car I have owned... or so I thought.
With 1400 miles on it things changed. I was driving down an interstate road, for anyone who knows the area I was on the I-17 south of Flagstaff headed towards Phoenix. The speed limit is 75 even though it gets to be a pretty steep grade at certain parts and at times there is a sharp dropoff on one side of the road.
Doing about 80mph down this road, and actually thinking about how cool this car is, all of a sudden everything went dark. The entire electrical system shut off and the motor stopped. I was barreling down the road with nothing working, including power brakes and steering.
Luckily for me I am a big guy in my 30s, and was able to control the car to a stop at the side of the road without power steering and brakes. But I think about the "typical" Buick buyer of an older man or woman and think many people who were on the stretch of road I was on would be dead had the same thing happened. And all we would know is that they were in a wreck and no one would know that there was actually a major electrical problem with the car that led to it.
At the side of the road the radio and OnStar actually still worked, nothing else, so I called OnStar and had them run the remote diagnostics to see what the problem was, all they could tell me was that the car had a major electrical problem and needed to go to a dealer right away, which since it would not start or do anything else, meant towing it from the middle of nowhere.
That's also when I found out about how the "FREE TOWING" from GM works. I wanted it towed 90 miles to the dealer by my house, and since I was in the middle of nowhere that seemed fair. They wanted to tow it to a dealer in a very small out of the way town called Cottonwood that was officially closer. Since I for one did not even know where that is, two - needed my clothes and daughter's items from the back, and three - did not want to have to travel way out of my way during the week to find this place, I was on the hook for the towing, almost $200. So much for free.
The dealer got it Monday night, and spent all of Tuesday working on it, and cannot figure out what is wrong. It is definitely fried, after a day of trying the dealer still can't get it to start up or the electrical to work. I stopped by late Tuesday to check it out and grab some more things out of it, and sure enough they had a bunch of wires and a few computers connected to it and are stumped. My new Buick LaCrosse is DOA.
Within the next few days I should know more and will post it, am searching now to find anyone with the same issue so want to leave this here for future people with the issue.
But the hard part is even if they find it, I do not want this car anymore. How can I ever trust it to not try and kill me again? Why wouldn't it even pop a warning, a check engine light, something before just dying on me? I will never again be comfortable taking a long trip in this car, or going very fast, always thinking it is about to die on me.
I was really hoping that this car would be GM's statement to the world that American cars are back, and I wanted to reward them by buying one. Now I fear I will forever be stuck buying imports. Our carmakers just aren't what they used to be, sad.
