2011 Chevrolet Silverado 1500: engine failure

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.

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.

The engine in this vehicle burns/vaporizes oil at a rapid pace. I have a 2011, 114k miles, and had to replace the pistons to the tune of $5400 - chevrolet would not help with costs. 6 yr old vehicle, just over 100k miles and have to replace the pistons.. I had kept up all scheduled maintenance at the dealership. Have a "warranty forever" , life time power train warranty, and denied my claim because it was due to 'wear and tear'. How can my 6 yr old, 114k mile vehicles essentially need a new engine? Chevrolet should be disgusted with themselves. I know many others with similar year, same engine and have the same problems. This problem should be investigated. I have not faith in the chevrolet product anymore.

The automatic belt tensioner pulley is in the process of going out. The pulley itself is slowly suffering from a high pitched whining noise which is caused by bearing failure. With the current mileage the part in question shouldn't by any means be failing, the tensioner works fine but the pulley wobbles a bit too much. If the pulley continues to wobble more and finally results in catastrophic failure it can shred the serpentine belt which will render the vehicle useless or even become a danger to any and all occupants in the vehicle especially if it fails on the highway. If the belt goes out it can bend other pulleys or shear off pulleys, bolts, or even bend the harmonic balancer (engine vibration dampener) which would result in a blown or seized up engine. I'll also add that the belt could cause a fire if it gets wedge between other spinning pulleys at the time of the pulley's bearings overheating and the pulley either breaking off or causing the belt to shred.
