Rusted out/ corroded brake lines burst while stopping for a deer running out on the road. Was warned of this problem upon purchase of the vehicle in 2010 and personally coated all brake lines b4 winter every year...never saw worse lines! I own classic cars that are twice as old with shiney original brake lines. The fuel lines also rotted out spilling fuel over the top of the fuel tank and on the ground while filling up. All fuel lines and fuel pump connections were severely rotted. Worst I have seen. Dash consistently changes languages rendering odometer non functional. Speedometer is inaccurate some times not even working especially on cold days. Hmmmm rotted brakes+no speedometer+leaky fuel lines=crash,bang boom!..and I have a car seat in my vehicle! Luckly I perform preventative maintenance and drive safely. Still wonder how these issues got swept under the rug.

The heating and AC controls were replaced 2 times in 2007.and are still not working properly today I was driving home with the AC on because it's 99 degrees in los angeles county and like it has been doing for years it started blowing hot air on its own. I have see other gm vehicles with the same issue. So I believe gm is responsible for correcting this issue.

Ignition will not turn over. Battery is fine, everything works except turning over. When you turn the key nothing happens everything goes dead. I have a video.

I have a 2004 gmc sierra that has an electrical issue with the ABS or brake system. The brake light, ABS light and service brake system light goes off at random times. Might have something to do with the air conditioning because the A/C draws power from the battery and I can see that a certain level the indicators go off. Most of the time the lights chime and blink when I apply the brake but it also has happened when just turned the truck on. I've replaced the rotors and pads to still have the problem. I'm not sure if it's a ground or sensor that is failing. I've found tsb for regrounding, failing sensors, or ecbm. Still haven't found the correct diagnosis. I just hope the ABS functions when I need it.
