Brakes
1999 GMC yukon was taken to russ darrow waukesha, inc. Cadillac/GMC for unwanted antilock brake system (ABS) activation. Dealer suggested this could cause increased stopping distances which could lead to a crash. Dealer informed vehicle owner of recall NHTSA campaign 05V379000; wheel speed sensor cleaning. That recall listed a 1999-2002 yukon, dealer went on to say that this specific vehicle was not coverd? VIN#[redacted].

While returning home from work today I approached a traffic light, pressed on the brake pedal and my foot went straight to the floor. I had to turn into the grass median to avoid hitting the cars in front as I pressed the emergency manual brake. Because I was very close to home at that point I was able to continue driving while using the emergency brake to stop. I checked the brake fluid level and it was within normal range.
Electrical system
On April 4, 2006 at approx. 5:00 pm our 1999 Denali GMC caught fire and was destroyed. It started to lose power and then immediately burst into flames and was a total loss. I feel this was a manufacture defect of some kind and would like to have this investigated. I do have pictures to provide you.
I purchased a 1999 yukon Denali from my former brother n law; he didn't inform me that my windows, door locks, radio,and windshield wipers would stop working. I was told that I needed a body control module; one GMC mechanic asked me what does this part do. I'm a lady how would I know these things. I still don't have my vehicle repaired. Will this cause me other problems or can I continue to drive off a wing and a prayer?
