NHTSA complaint #10328240, filed 2010-04, 78,000 miles“Electrical problems and door problems - I bought my Blazer when it was 2 years old with 8300 miles on it. With about 13000 miles on it the vehicle would not stay running and the battery gauge was under 9. I got the vehicle started and drove to the dealership. They replaced the alternator. They would not cover a loaner or rental since I was able to drive the car to the dealership. If I would have had it towed they would have covered a rental. 2 weeks later same problem repeated. …”
NHTSA complaint #10052832, filed 2004-01, 17,400 miles“I was in a drive through which looped around the building. I applied the brake to stop at the window and could feel the ABS engage and the vehicle did not want to stop. It scared me and of course I reapplied the brake quickly, to avoid hitting the vehicle in front of me, and I was finally able to stop. This happened again a few weeks later at a large intersection at a red light. I was 7 months pregnant at the time and was pretty scared. I have heard several of these complaints and I know that the brakes on every year before this were recalled. …”
NHTSA complaint #10184068, filed 2007-03, 75,000 miles“I am pregnant and very scared to drive this vehicle again. I was told by rick, service manager, toni hall at flow Chevrolet a year ago that this 4x2 and 4x4 wheel drive was corrected while under warranty. They refused to fix the major problem and changed out a switch. During this whole year I haven't been able to drive comfortablly. Now they have had to replace the whole front end. A brand new car now with only 39,000 miles. The noise is terrifying and I've been insulted by GM with a loyalty incentive for $700 to take off on a new vehicle. …”
