Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Engine died while driving 60 MPH on the interstate in snowy conditions on 2 lane portion in heavy traffic. By the time I coasted to a stop with no power steering or power brakes I was on an overpass with nowhere to pull out of traffic, so ended up blocking one lane of traffic for about 2 minutes. Obd ii code reader showed no code errors. Replaced fuel filter. Did not fix problem. After checking NHTSA site as well as others on the internet found it might be the ckp (crankshaft position sensor). Took it to dealership where their diagnostic tool verified it was the ckp. …”

NHTSA complaint #10422115, filed 2011-08, 137,000 miles

“2002 chevy AVALANCHE 2500 with 8.1 engine dies without warning at driving speed. The battery light comes on, after the vehicle shuts down, but no check engine light, no problems with alternator or battery charge. No sputtering or sluggishness, no warning whatsoever. The vehicle just shuts down. When this happens there is no power steering and no brakes for this 7k pound vehicle! Sometimes, once pulled over and shutting everything off and trying to restart it will restart immediately, sometimes it takes up to 10 minutes of trying to crank it intermittently before it will restart. …”
