2011 Chevrolet Silverado 1500: doors won't lock, open or latch

Filed Jul 24, 2022 · Engine · AR

Vehicle door locks activate lock and unlock while simultaneously downshifting the transmission, the engine dies, the dash cluster stops working, engine starts again, dash cluster begins working again. After this occurs, when the vehicle is shut off, there is a loud "pop" sound heard over the speakers and no interior lights. The vehicle may or may not have any cab power. Cycling the ignition provides little to no help. After the vehicle sits for a while, it may or may not start again. The vehicle stereo will randomly change from FM to aux. The a/c panel will flicker and the blower motor will fluctuate. This can also be seen while watching the battery gage on the instrument cluster. It will go from around 14 volts DC to around 9 volts DC and back up again.

**randomly at any given speed ** First the radio system will randomly turn off then moments later… stabiliTrak off flashes followed by abs and traction control lights on dash then suddenly my Chevrolet Silverado has a mind of its own ! The door locks will flicker uncontrollably , and the vehicle just suddenly has a loss of power while rpms and gauges are continuously moving while you are unable to even move the vehicle .. this is a ongoing problem since 2019 , that no one seems to have an answer too .. I’ve taken it to 3 different mechanics and still no answers … when it first started happening it was super random and would happen a few times a day but then not happen for months on end then all of the sudden now it is happening several days a week .. I’m currently scared to even drive it which is horrible considering the amount of money I’ve put into this truck .. it has only 100k miles but somehow I am stuck using my dads old truck with 330k miles on it which seems to be more reliable and is 12 years older … sucks to pay over 500$ a month for “ your dream vehicle “ that you can’t even drive or get any real answers to what or where the problem is coming from … seems that thousands of people online have the same problem but yet no one has any solution .. Now that I’ve almost been in 3 serious accidents I decided I have to say something, 2 of these times were over 70 mph on a California freeway !!! Something must be done !

I have had an ongoing problem with the electrical system in my truck. First time it happened I was leaving my house and as soon as I got a few houses down the road my door locks started unlocking and locking themselves over and over and the speedometer gauge was all over the place along with the RPM gauge and the road up would turn off and on and the brakes would lock up and then release and it did this until I was able to pull over and turn the truck off. Once the truck was off it wouldn't start again. I had taken the battery out to be tested and it was fine. The alternator was fine and as far as I could see the negative and positive cables from the battery were clean too. I've traced the ground and it doesn't appear to be in bad shape either. Well after I was able to get it back to my house it sat for a few days and after a couple days it randomly started back up. Took it to the local chevy dealership and they said there is no problem everything is good and they couldn't recreate the problem. They said it could be the aftermarket head unit. Well once I got my truck back the head unit no longer works or gets power? Well now a month later same problem and the truck is totally dead but battery and etc is fine.

Driver side inside door handle broke off while parked as I was exiting vehicle.. Inspection of handle showed a crack on the handle where it broke. It appears to be a defect of manufacture and design. The repair required the complete replacement of the driver side door panel at considerable expense. The potential for safe egress from the vehicle in an emergency is of concern.
