general problems of the 2011 Chevrolet Silverado 1500

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.

There was no accident to my vehicle I purchased a new vehicle from a company and I have been having problems out of the vehicle since I made the purchase. The dealership replaced the tires, then replaced one of the rims but the problem still exist they also did a front end alignment, the service manager stated that he had no idea what to next to solve the problem, there is a shaking or vibration in the vehicle when it is driven. I have had several conversations with gm and still the matter hasn't been resolved.

Conditions: heavy misting rain, 32 deg f, lowering temperature, daytime. This is to report a design defect of the windshield defogging system. The defogging system operated as designed. There was no failure of the equipment. When the windshield defogger is selected this vehicles system automatically sets to outside air and turns off the airconditioning conpressor at 32 deg f and below. On December 6th while driving during misting rain at slightly above freezing with the temperature slowly lowering I experienced a rapid and serious problem clearing the windshield of mist on the inside surface of the windshield as well as all other glass surfaces when the temperature fell below freezing and the airconditioning compressor cut off. Despite using the windshield defogger at the maximun heat and fan setting I was forced to pull over to the side of the road because I could no longer see well enough to drive safely. Selection of windshield defogging mode actually worsened the problem initially. I believe that the design of the system creates the potential (and in this case actual) danger of rapid loss of visibility to the outside of the vehicle with the possibility of a loss of effective control.
