Twice i have encountered un-commanded rapid acceleration while driving at approximately 45mph. i was able to get the acceleration back under control by pressing and holding the brakes. it has happened in the same location, i'm guessing it is some sort of radio signal interference.
The check engine light blinks off and on,traction and stability goes off then back on ,engine runs and idles rough and sometimes shifts hard.this happens while driving and sitting still (for the lights and rough idle) not the hard shifting. while searching on internet ,found it was a common problem with the 5.3l chevy/gmc engine.
Engine uses 3 quarts oil between required oil changes. #2 problem 4wd switch if i use auto 4wd . 4wd does not engage and wont switch out of auto .i was told at dealer ship just don't use auto 4wd it has always been a problem
While at low speeds, usually during a parking lot maneuver type condition... my truck's entire electrical system seems to shut down several times for like a second or two at a time. but it happens rapidly. llke 4 to 5 times within 10 seconds. due to the electronic steering not operating when it does this, it will bounce the steering sporadically when it cuts on/off and kind of scare you. at the same time the sad lights flicker and the door locks lock and unlock rapidly. even as a veteran driver, it all happens so fast that you cannot regain control easily. when i stop, turn the truck off then restart it, it's been ok. this has only happened 3 times. but it clearly seems to be a problem with the ignition system shutting on/off really fast.
Tl* the contact owns a 2013 chevrolet silverado 1500. while driving at an unknown speed, an abnormal noise was coming from the engine. the vehicle was taken to big city auto (4910 lima rd, fort wayne, in 46808). the contact was advised to go to summit city chevrolet (5200 illinois rd, fort wayne, in 46804). the vehicle was taken to the dealer and the engine warning indicator illuminated continuously. the dealer diagnosed that the lobes rounded off the vehicle and the exhaust lifters collapsed. the vehicle was repaired. the manufacturer was notified of the failure. the approximate failure mileage was 133,000.
My truck has been consuming excessive oil. i have used the synthetic oil that is specified and changed the oil every 5000 miles. took it to the dealer and they said they have identified problems with the engine but my warranty has expired. i had to spend another $2,000 for an extended warranty to cover the future fixes they described. there should have been a recall to fix this problem when it was identified. i bought this vehicle new and have never been told of the issue until i complained to a chevy dealer. they know it exists yet they try to fix it with a band-aide type solution. in the end i had to spend $2,000 to cover a problem they knew existed yet did not let me know so i could bring it in before the warranty expired. now i am told i have to endure an oil consumption test requiring me to drive 45 minutes to the dealer, wait for my test and return again. then they experiment with three different things that might fix it before they replace the engine costing me time, money and inconvenience. as i type this i have to endure the chevy truck commercial that says they are the best built, longest lasting truck. i am disappointed and frustrated. i should have been notified of this problem long ago.
