Driving freeway speed lost throttle/acceleration control and power, gages went out of control dropping to zero coming back up and then dropping again, radio shut off and clock reset. Locks were locking and unlocking on their own then truck shut off. Had to coast to side of freeway. No hazards lights would work no blinker. Once parked on side of freeway turned off ignition and truck would not start no power no nothing. Had to disconnect battery then connect again before it would start back up. Was told engine was rebuilt by car dealership I bought it from carfax doesnt show that but does show a possible odometer roll back and a new airbag recall was issued. I just got carfax report today havnt had the truck for even a year.

Rapid temporary loss of engine power, doorlocks cycling repeatedly, guages malfunctioning, radio shuts off and turns back on with no preset stations and showing 12:00 on the clock ,cruise control disengages. Once vehicle is shut off, no guages nor lights work...as if there wasn't any battery in the vehicle. Vehicle won't start until dome light is restored on via jumpstarting. Cleaning battery connections and numerous ground wire connections gives short-lived relief from symtoms but problems ultimately return. Chevy dealership diagnosis shows that ground wires have high resistance. Online research shows that tens of thousands of other chevy owners are having similar to exact same problems, yet no recall has been issued. Problem was "fixed" last year and has returned yet again.

Experiencing sporadic issues with my trucks electrical system. What will happen is that as I'm driving down the road (doesn't matter what speed), I will hear a loud "pop" (sounds exactly like a desktop computer losing power) and then my dashboard/monitor screen will go dark and after a split second everything come back on. The dashboard will flash on and off for a few more seconds. About every third time this happens, if I park the car and try to restart it it won't turn over. In these instances, I can hear current cycling through my power door lock switch along with an electric clicking noise that won't stop. If I let the truck sit for 15 minutes or so, I can get the truck to restart. I have had to have it towed a couple of times because I could never get it to turn over. This problem first occurred when the truck was 3-4 years old and still under warranty. They couldn't find the issue and didn't replace any parts. Now all the repairs are coming out of my pocket. I've replaced the battery a couple times thinking I had a faulty battery. Later I replaced the battery cable thinking this was the cause and most recently replaced the fuse box. In all instances, the problem would go away for anywhere from 3-6 months and then reappear. As I said it is very intermittent with no consistency to it whatsoever. My truck has never died while driving when this has occurred, although I'm scared to death it will do so and I'll lose all power. My brother-in-law is a master mechanic for a local dealership and it has him completely stumped. He's read through all the tsb's, checked on-line blog's, etc. As well as doing his own technical troubleshooting, but cannot pin down the exact issue. At this point we've resorted to replacing the most likely parts and hoping for the best. As I said I replaced the fuse box about 4 months ago and the problem resurfaced today.

I have a short in my fuel pump flow control module. It causes my car to stall while while in operation, check engine light comes on, sometimes it doesn't start, etc. This issue has haunted me for about a year now. I found a recall bulletin from gm; #14515b. This is the exact part # and issue that I'm having but my VIN # isn't part of the recall. Is it possible that my VIN was missed?

Truck would not start so I put the battery charger on it, on slow charge. About 2 hours later I heard a loud bang, walked out side and both air bags had deployed and busted the windshield.

After having driven vehicle a short distance for an appointment, truck would not start an hour later; however, lights came on dash. I waited 10 seconds and tried it again, and it started no problem. Then no problem starting the next time but driving around town the radio start shutting off for about 3 seconds before coming back on. This happened a few times, then as I am driving, the entire electrical system starts going haywire, lights flashing on dash with warning lights & messages going off on dash, then everything but the engine shuts off (dash lights, gauges, radio and A/C), after about 5 seconds everything comes back on. I immediately drive to my mechanic who hooked up the computer to my truck and said it was my ignition switch. He said he could not get me in that day and asked me to bring it back the next day. So the rest of that day I did not have any further problems with it. The next day I took it to my mechanic and got the ignition switch replaced. While the mechanic had my truck for several hours until I could go back to pick it up, he said he started it many times and it appeared to be fixed. So I leave the mechanic shop and go back to work, then get off work 2-3 hours later and my truck will not start. After attemping it 3 times, it started. I drive home which is 10 minutes away and turn the truck off and back on. Only when I attempt to turn the truck on, it will not start. This time nothing happens...no clicking sound or any attempts of the engine wanting to start....no lights on the dash like before. It was 2 hours later before I was able to get just lights to come on the dash, then another 30 minutes went by before I was able to get my truck to start. This is day 3 of dealing with it and I drove it to work and back home with no problems. I called mechanic who said sounds like a grounding problem. I said sounds like computer system.
