The contact owns a 2011 Chevrolet Avalanche. While driving 35 mph and attempting to engage the brakes, the vehicle did not slow down and the ABS failed. As a result, the contact's vehicle crashed into the rear end of another vehicle. The air bags failed to deploy. The contact sustained unknown injuries, but did not require medical attention. A police report was filed. The vehicle was taken to the dealer. The technician verified that the ABS failed and needed to be reset. The contact asked the manufacturer for a new ABS brake module under the warranty, but the manufacturer refused to replace the ABS brake module. The failure mileage was 24,500.

Avalanche 8-cyl

  • 600 miles
First few months experienced truck lunging forward whilst attempting to stop. Expressed concern with service dept. They stated nature of the vehicle performance. March 2013 called GM service #[xxx] after experiencing on highway @ 65 mph the vehicle accelerating as I applied brake to slow down RPM's jumped to 4500 and accelerated. 3/21/13 mileage 24,565 was told by dealership no codes were found. Was referred by GM to tech specialist 3/26/13 @ 866 790 5700 ext. 32664 told to get second opinion then completely ignored by GM for follow ups. April 1st different dealership found code event stored in transmission control module from March 15th but no diagnostic was present, they cleaned the throttle body. Mid April 2013 brakes began pulsating on compression. Mid April frustrated and very concerned with safety called 800 lemon law found on line and kimmel & silverman advised GM / GM responded disclaiming issues. @ 28,429 miles 5/21/13 front rotors replaced and rear rotors resurfaced. Transmission dipstick tube fracture fix: Pipe insulation & zip tie. 8/20/13 brakes pulsating again & spongy - vibration noted by service but not addressed.brought to specialist; right rear rotor grooved & left rear had chatter marks. 8/29/13 went to amco they found 4 codes in truck on GM scanner which dealership denied there were any. Sept. 2013 received bulletin " throttle position sensor may cause engine to run rough ". getting no-where with GM or dealership and fearing for safety in Oct. 2013 I opted to trade the vehicle at a great loss as it was my only transportation. Mind you this was my 2nd Avalanche - the 1st one I'd had a front end accident; air bag never deployed, fortunately I was not injured and deemed the performance issues to be due to the accident and traded into this new Avalanche. I have documentation for all of this and have lost over $30,000 due to GM negligence. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
