Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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. …”
