Cylinder 6 misfire. The mechanics have replaced everything that could be triggering the cylinder 6 misfire and still it is having problems they said the only way to fix it is to replace the engine but I should not have to replace an engine with low miles and that has been babied. I have also looked on multiple sites with people who own the same truck and all have the same exact problem with the same cylinder. Something needs to be done about this issue especially if it’s a reoccurring one, either have a recall on it and fix it or something.

Vehicle stabilitrack and traction control lights came on. Engine warning light came on. While attempting to turn the vehicle onto a highway acceleration ramp, the car steering wheel locked and the engine died. Could not unlock the power steering. I was towing a horse trailer well within the gross weight for the vehicle. I had a horse in the trailer at the time. I also had children in the car. After a few minutes, I was able to start the vehicle and pull into a safer area. I was not able to tow the trailer home but I was able to get the vehicle home. The car hesitated and chugged along surging into each gear. While at a stop the vehicle hesitated and the engine sputtered. I had to put the truck in neutral and put my foot on the accelerator so the car engine would not die. The transmission would surge each time I stepped on the gas. Limited turning radius on the vehicle and I was not able to make a sharp turn without a grinding noise.

2007 chevrolet silverado 1500 5.3l engine. At 40,000 miles, the camshaft and a couple of lifters were replaced due to wear and eventual tapping. Again at 90,000 miles, the camshaft and a couple of lifters (lobe 4) were replaced due to lifter wear and breakage causing engine tapping. On the second occurrence, after the lifters had started tapping (and 900 miles from home) a piece of a lifter broke off and caught in the oil pump causing it to stop. I quickly turned off the engine to avoid further damage. Upon this second occurrence of lifter failure causing the camshaft to wear, I felt sure that chevrolet and gm would replace the engine with a short block but I was extremely disappointed. Gm and the chevrolet dealer admitted that a camshaft should last as long as the vehicle but I am on my 3rd camshaft in this engine before the warranty ended. One tried to convince me the camshaft was probably of a bad lot made but these 2 occurrences were too far apart for me to believe that a recall would not have occurred during that time. The other (gm) tried to convince me that the camshaft wore out the lifter but I don't buy that excuse either. A new set of tires lasted longer than the engine on both occurrences. I believe the problem is still there. I still have the defective engine block in my vehicle which causes me to doubt the engine dependability and will cause a reduction of the value of my vehicle when it is time to sell or trade.
