Power surges sometime everything shuts off while driving leaving no brakes, steering, or acceleration. Other times there is a no start due to no power or the instrument cluster goes haywire. Reacquiring problem with no answers why. Others have had the same problem. Scary driving fine at 60 with kids in the back and all of a sudden you lose control of your truck unexpectedly for the first time. No Warnings or OBD2 codes.

After buying this used truck from GM certified dealership having advanced inspection before we took home 3 months in First start of the day about 7AM, 5-10min into driving, no MIL light, truck engine shut off hard to pull over and I tried to restart but wouldn't start. After waiting an hour for a tow truck I tried once more and it fired up. Cancelled tow drove home fine. But it did it a few more random times while driving until Oct. now it sits. Its scary when theres no MIL indicating a problem, but this is a problem and safety during travel. It wont start after 7 month ownership ,MIL light is now on saying U0100. Bought 4/2021.

2007 Silverado 1500. Has had a situation where truck acts a dead battery or no battery in the truck. Conditions are no start, key fob will remote start truck then truck dies all electrical in truck works. Have dad CD player shoveling cds when no key in truck. Air and heat switch’s back and forth. Door locks cycle up and down. Have to reset radio and clock after the power failed. This is not from a dead battery. All I do to reset it all is to put a battery booster to battery terminals and switch booster on and off. Truck is back to normal. Most recent advent was all this at 1 time. Door locks cycle, radio turns on and off, ac changes to heat, low fuel and seat belt alarms start sounding, instrument cluster act irrationally, speed odometer goes from 20 to60 back and forth with truck cutting off at 20 and powering to 60. After several miles of driving everything is back to normal and I drive straight to my mechanic. Cut the truck off and Bingo, acts like there is not a battery in the truck. Nothing at all electrical. Total silence. I have had minor electrical since truck was almost new. I always carry a booster pack and it worked to start truck and get me home. Now for what my mechanic found after my last disaster. There is a high amperage fuse block located under your fuse box in the engine bay. There is 2 threaded studs for wires that feed your trucks electrical. Studs had never had ant nuts on them to hold the wires secure and after 14 years of total aggravation and fear of an accident or fire. I hope truck is fixed for good. GM dealers would blow me off with any excuse why they couldn’t find a problem. They wanted to sell batteries , Pcms and ecms. The reason this becomes a safety problem is a chance of total power failing while in traffic being rear ended or worse. There really should be a recall for these trucks and checked. I’ve read hundreds of remarks from people with these same issues. I hope this helps. I am thankful to have a mechanic who will research.

C1500 at times when stopping will shut down, all lights on the dash board will light up and whole truck will shake. Took to chevy dealer ship they said needed new motor.. Already put top end of motor in 1 1/2 years ago - same thing is happening now but they say needs new motor. Let truck set for several days, crank it and it seems to be ok. But don't know when it will do it again. If needed a new motor it would not crank and drive. Chev. Dealership was going to charge $6,000 for new motor and labor. And obviously that is not what is wrong with it. 08132018

Vehicle stalled while drive down the road nearly causing an accident. Would not start again. Dealership diagnosed the problem as the fuel pump control module, this issue had been addressed in bulletin no: 14514b, but it was labeled as "VIN specific" because my VIN does not fall into this specific range there was no recall issued even though the issue I experienced is the exact same issue.

Multiple occurrences. Clock resets itself. Turned key to start, no dash lights, no nothing..I retried after a couple of minutes, it started. Fuel pump stopped working, no power to it I was told. Fuel pump was new 2/10/13. They replaced the fuel control module 4/18/2013. Connections were cleaned and reset. This all worked fine until 3/12/2014. Same situations started again. But as before it would always eventually start. Same diagnosis, fuel control module and a some other expensive stuff. 3 weeks ago it didn't start, would grind with no fire. Fuel pump isn't getting power. I'm dead in the water. One of my sons works as a carpenter, welder and shipping specialist for a classified government facility. This facility has top notch mechanics to do all their maintenance including autos, going outside of the facility is not an option. These mechanics have 7 chevy 1500s of various years they have to keep running. They've offered that all of their trucks had the same issues as mine at one time. For the first 2 they did the module replacement stuff just like I did. Just like mine those fixes went south again. What they did then was to change out the entire ignition module with an improved version. They've done it for all 7 vehicles as the issues occurred, all are now working well, some for years. I'm trying that next. There may be some security items to fix. It seems to simple to me, but as I look at all of the interfaces of the vehicle with the ignition module, I'm giving it a shot. By the way battery connections are good, grounds are good, fuses are good, I have a basic 2007, manual windows and no remote stuff. If they'll let me I'll post the results.

When driving the truck the lights would dim and then have a loss of power. Didn't think much of it until one day getting out of the vehicle and shutting it off I went to put the key back in the ignition and there was no power what so ever no dome lights nothing... No clicks no dash lights nothing. Then had someone jump me power and truck started right away. Same day had my battery checked and alternator and everything came out fine nothing was wrong with it. Happened again about a week later but this time truck hesitated when key was turned then it did not start reset the clock in the truck and then had lights dimming everytime blinkers were turned on. Got home and had a feeling truck would not start if I took the key out sure enough everything was dead when I tried turning it back on. Had to jump it again. When that happened I got the battery replaced thinking it was faulty. Two weeks went by and it was fine then after punching on the gas a little to pass a semi the locks went up and down really fast and had lights dim again no message on the dash or anything. I got home and truck did not start again. Jumped it again then a week later going to work on the freeway the truck had extremely bad tremors and then the locks started locking and unlocking again the lights and stereo were going on and off and ABS light came on and vehicle kept going into neutral and drive every other few seconds witch caused a concern for my safety. Good thing I was only a few miles away from home. I turned around went home and sure enough turned it off put the key back in and no power . Explained failure to a dealership and said possibility was the ECM. And they could do nothing unless it was duplicated.

While listening to the radio, while truck was off, through auxiliary input, the truck suddenly cut off. I lost all power to power steering, power windows, lights, dash would not indicate what gear the truck was in, and of course truck would not start. Had to have truck towed to dealership, which they found the bcm had gone out. The dealership found that there was no voltage surge and no reason for the failure. A new bcm was placed in the truck at a 600$ expense to my self, and the truck is fine now. Still worried about why it happened and what caused it so I know it won't happen going down the road, or if I am in an unsafe place.

My truck will not start all the time. 60 days after purchasing new truck I started having many dead batteries. I was receiving emails from onstar at same time telling me they had diagnosed my truck the preceding night. I advised onstar to stay out of my truck because of the problem. About 5 months later (november 2008) I started having problems again. I had another dead battery. Latest happened 1/16/2009 truck would not start but battery was fully charged. I had truck taken to dealer. Dealer got it started and said they could not duplicate the problem. They did not fix anything. I pick up truck 1/20/2009. 1/21/2009 I started truck with my remote, got in truck, inserted key and then turned off motor. I tried to start it again and truck would not start. I waited an hour and tried truck again. The truck started. I drove it immediately to a different dealer. Gm called me 1/23/2009 and said they could not find any problem with my truck. I have had this problem for 12 different times. One time the radio was overheated when battery was dead, but lately the battery is not dead. This truck is proving to be very unreliable and I am very frustrated. Can you help me!
