On multiple occasions the vehicle has lost power at highway speed and the engine dies. After a few attempts the engine restarts and operates normally for an unpredictable interval. This has happened at least 10 times. The authorized dealer and other mechanic shops have not been able to diagnose the reason for the power failure as they have not been able to cause it to duplicate failure when they have it. This sudden unexpected condition is very dangerous when it occurs and renders the vehicle unusable for anything other than short usage.
The bolts are broken off in the manifold, after checking you-tube I found this is a problem the gm has chosen to ignore.
On 09/10/13, 1:45 pm, I was driving east on s. R. 73 near I-75 intersection. As I approached the intersection traveling approximately 35 mph, the light changed to yellow. I braked somewhat hard and the brake pedal went to the floor board. There was no braking control at all and I proceeded through the red signal. Approximately 500 feet after going through the intersection I managed to stop in the median. Fortunately, although traffic was heavy, no contact occurred. Immediate inspection revealed a brake line rusted through. I trailered the truck to a Chevrolet dealer who found not only "all" the brake lines were dangerously rusted, but the gas lines also were dangerously rusted. The dealer stated this was a common occurrence with Chevrolet silverado. Replacement of these items required removing the truck bed which revealed the brake rotor backing plates rusted "away. " severe frame and component rust was also found. Only repaired brake and gas lines. Cost, $1,765. 11 OH, by the way, the "service brake system" warning light came on after brake failure.
Vehicle will suddenly decrease power and the message "engine power reduced" shows on message display. First time was 9/8/2012. Last time was Feb 24, 2015. Has done this at 25 mph on a city street, 35 mph city street twice, and 55 mph on highway. Supposedly repaired three times. Am afraid to use vehicle as usually tow 5th wheel and do not want it to do this while towing.
