2012 Chevrolet Silverado 1500 Engine Problems

Your engine stalls when you apply gentle acceleration, and it feels like your tires might lock up or something in the drivetrain could break. The dealer says this is normal behavior, but you believe it's a safety concern. The issue likely involves the fuel delivery or ignition system not responding properly during acceleration.

Oil consumption on 2011 to 2014 Chevy Silverado engine related issues on the 5.3 liter v8 flex fuel engine. Vehicle produced a service engine soon light on 9/27/2022 so I took it to the local Chevy dealer mechanic. They inspect it and determine that it was a misfire in cylinder 7. They went to run it through my warranty that I purchased when I baught the vehicle 2 years ago. They advised that it would not be covered so to it being an oil consumption issue. They advised that to fix the issue permanently it would cost $3,600 to fix. Being that this is a known issue GM should be issuing a recall to correct this. I only have 60000 miles on the vehicle and the engine is basically junk without the fix. I do not have the repair invoice at the this time as it is currently in the shop with the local Chevy dealer The mechanic advised that this is a known issue with all Silverado’s between 2011 and 2014 and that GM knew this was an issue and that eventually the engine will sieze if you don’t have the pistons and rings replaced. This is a country wide problem and appears there is a possible class action lawsuit due to GM knowing this was an issue and in 2014 GM re-engineered the 5.3 vortec to correct this issue. In addition it is a known issue another problem is the rear wheel wells rusting on all Silverado’s. This should also be looked into Thank you for your time and consideration!

While driving the motor completely cut off. Yes, the vehicle can be inspected. The vehicle just shut down without warning, causing the vehicle to rapidly slow down with no warning to other motorists behind me. Yes, a dealer has confirmed the problem and could not definitively determine what the problem is. they said it could be: A shielded wire, service dept. said its not available from GM and would have to purchase the entire wiring harness and install to see if it fixed the issue. They said it could be a bad power inverter, again had to install to see if it fixed the issue. Finally said it could be a bad transmission(??) The only people who has attempted to diagnose is at the GM dealer service department. Their was no warning that the vehicle was about to turn completely off prior to it doing so.

EFM ISSUE: LIFE-TIME CHEVY SILVERADO OWNER, CURRENTLY OWN 2003 & 2012 1500 SILVERADO 1/2 TONS. EVER SINCE GM STARTED USING EFM CHIPS, FOR SOME UNKNOWN REASON THE ENGINE WILL LOSE SEVERAL QUARTS OF OIL FOR NO REASON. WITHOUT WARNING THE CHECK ENGINE LIGHT COMES ON. PULL-OVER & CHECK THE OIL LEVEL. ON EVERY OCCASION, (SEVERAL INCIDENTS NOW), MUCH TO MY SURPRISE THE OIL LEVEL BARELY REGISTERS ON THE DIP STICK. WHERE DID 3-4 QUARTS OF OIL GO? YESTERDAY THE OIL LEVEL WAS FULL, TODAY THE OIL LEVEL IS ALMOST NON-EXISTENT - WITHOUT A DROP OF OIL LEAKING ANYWHERE? I NOW HAVE TO CARRY 3-4 QUARTS OF OIL WITH ME EVERYWHERE I GO JUST IN CASE THE CHECK ENGINE LIGHT COMES ON. GM SHOULD DO THE RIGHT THING AND ISSUE A RECALL. WARNING: IF YOU DRIVE A CHEVY YOU BETTER KEEP 4 QUARTS OF OIL WITH YOU AT ALL TIMES IN THE EVENT THIS HAPPENS TO YOU. NOT IMMEDIATELY PULLING-OVER & FILLING THE OIL LEVEL BACK TO PROPER LEVEL MAY DESTROY YOUR ENGINE. FIX THIS EFM ISSUE > LOSS OF OIL, AS IT HAS BEEN GOING ON FOR YEARS AND STILL PERSISTS AFTER 2 COMPLETE MODEL CHANGEOVERS. THIS MAJOR MALFUNCTION IS THE RESULT OF THE EFM SYSTEM DUMPING THE OIL INTO THE EXHAUST & THE CATALYTIC CONVERTER BURNING IT AWAY. THAT IS THE ONLY PLAUSIBLE EXPLANATION FOR LOSING SO MUCH OIL WITHOUT WARNING AND WITHOUT A DROP OF OIL BEING FOUND ANYWHERE OUTSIDE THE ENGINE OR UNDERNEATH THE ENGINE COMPARTMENT OR CHASSIS. *TR
