2011 Chevrolet Silverado 1500: check engine light

Filed Jan 31, 2025 · Engine, Fuel system · TX

The software that makes the truck work as a 4 cylinder truck has caused the engine light to come on and causing a code P0300 various engine misfire. The misfire is caused by the lifter spring causing the lifter to remain in the down position. The down position is against the can rod and as the cam rod rotates, this causes the lifter to break at the bottom and causing the can rod to also break which will cause an engine failure while drinking and the motor will freeze . All GMC and Chevrolet vehicles with this installed should be recalled. Everyone has been fixing it themselves by replacing the part(s) once a pinging noise is heard at 50,000 miles. Basically every 50,000 this will need to be fixed. Some people are turning off the 4 cylinder software to avoid the problem which in both cases, uses more gas and also idles higher.

While driving, all the sudden my check engine light came on (flashing), and my stabilitrack light came on. The engine started running really rough, and lost power. It is like major misfire. Upon reading up on this, it is a problem with this type engine. I saw about 2000 people with the same issue. Nothing works to resolve this problem. Coils, plugs, and wires were replaced, and still the same.

1 owner. Never driven on salted roads(south louisiana).live 100 miles from coastline,not in a saltwater environment. Or driven in water other than rain. Cruise control dropping out, automatic transmission not shifting when supposed to. Traction control dropping out, service messages cycling in and out--traction control, stabilitrac , anti-lock brakes, check engine light, red brake light comes on and off. Speedometer going crazy. Brought vehicle to gm dealer for inspection/repair. Cause- internal failure of ecbm-electronic brake control module, due to corrosion in the connector due to water intrusion. Had to replace the module, and the vehicle chassis wiring harness. Total repair was $1,830.39 for parts and labor. The dealer reported to me that the design/installation location of this module is flawed, and a faulty design allowed moisture to get into the module thru the connector.which also resulted in the wiring harness connections into the ecbm also becoming corroded.. Dealer also told me that this faulty design will eventually become a recall, and for me to keep my invoice of this repair, as to be able to claim a reimbursement for this repair.

In june of 2019 my vehicle was brought into begnal motors in kingston ny with the check engine light on. There was also a warning for the stabiltrax system and low oil pressure. I brought it to begnal motors because that is where I purchased the vehicle. The vehicle was still under warranty at this point. They being a dodge dealer then sent the truck over to romeo chevy who diagnosed it as an engine misfire. They had the truck for two months for the repair which the warranty covered. I got the truck back and soon after the engine light came back on. At this point the vehicle was no longer under warranty. It took the vehicle to my local mechanic absolutely auto in new paltz ny. They send a code for the oil pressure sensor and the o2 sensor where showing up. They replaced both sensors. After the work was done the oil pressure sensor still wouldn't clear and the engine light came back on. The mechanic told me that these sensors are known to have problems on the silverado. He then rechecked he's work to make sure there was a new screen on the sensor and there was. The code(p0521 I believe)still wouldn't clear. He then referred me to take the vehicle back to romeo chevy because they had done all the work on it previously. I brought the truck back to romeo and they did a complete diagnostic test and got no answers. They then did anther oil change and an oil pressure test with no result on clearing the oil pressure code. Romeo chevy has at this point had my truck for another three months unable to diagnose the problem. They now say I need a new engine and that the oil pressure issues cannot be fixed. Their service rep told me they had another silverado recently with similar issues and they had to replace the engine in that vehicle. I would appreciate some help in this matter the vehicle has only 105000 miles and I am being told it needs a new engine because of oil pressure.
