problem #2

  • 100,000 miles


The engine will go to low power and not go more than 30 mph without warning. This is an ambulance chassis and is a know problem GM has not addressed yet in the 2012 and 2013 chassis. It can do this on hwys with speed limits of 55, 65, 70 mph suddenly which could cause an accident as no stop lights give any warning and you can't speed up anytime in poor visibility or at anytime. Not only is it bad for the injured or ill patient it could cause an accident and injury others. GM has fixed this on the 2014 and newer models but not 12 &13. This is not just our one unit this is 2012 and 2013 Chevy diesels ambulance all over the us. We have four units that it can happen to and two that is has with patients. I have contacted the epa, GM, and our Indiana state senators trying to get this dangerous situation taken care of in the last few days. I am asking anyone who will listen to help push GM for a fix.

Express 8-cyl

This is a brand new bus, GM chassis. It has a limited slip differential. The brake lines are routed in front of the rear differential. Twice, we have had rocks hit the brake line and sheer it off causing total brake failure. [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
