Chevrolet Silverado misfire problems

Filed Jul 18, 2018 · Engine, Fuel system · 8,400 miles · WV

Engine hesitation, or misfiring. Jerking, or transmission shuttering when engine is at low RPM and on incline. (I.e. When traveling about 45mph and start up a hill, the RPM's are about 1300, and the transmission doesn't gear down, so it starts shuttering until you give it more acceleration than usual.) after dealing with this issue for nearly 8 months and 15k miles, I believe this safety issue should be recalled. Dealer originally acknowledge the problem but was unsure of the cause. After 5 repair attempts the dealer say they can't duplicate and the vehicle performs as designed.

I purchased a new (175 miles) 2017 chevrolet silverado ls 4x4 from a dealership on 2/10/2017. I noticed the ride was a bit bumpy on the 80 mile ride home from the dealership, but thought nothing of it. The next time I drove it was 2 weeks later (I was on business travel in between and let the truck sit in my garage), and I drove it around town on 2/25/2017. In addition to a minor rough idle, it was very bumpy. It would shake at virtually all speeds. After my 5 minute drive from the grocery store, I literally felt dizzy and ill. The next morning on 2/26/2018, I drove it to work (25 miles), and experienced the same feelings of motion sickness. I am a certified auto technician with nearly 20 years experience, and have worked on all components of cars and trucks (engine repair / overhaul, transmission, suspension, brakes, electrical, heating / AC, etc.). I've worked on trucks spanning a wide range of years with various issues and mileages (low mileage to +250,000 miles). I have never felt a more uncomfortable ride in a truck in my years of test driving vehicles (before and after repair) than I have with this new 2017 silverado. I attempted to contact landers mclarty chevrolet in huntsville, al, and was told that this safety concern could not be addressed at their dealership until the truck had at least 500 miles . I informed them of my concerns about driving it until then as I have under 400 miles on it, and they told me to drive 80 miles to the dealership where I bought it to have it looked at. Unbelievable! After much research, this "motion sickness" issue is a known issue by general motors, and does not have a proven documented fix in place to this day.

Tl* the contact owns a 2008 chevrolet silverado. While driving at various speeds, the vehicle misfired and a small tick noise was heard under the hood. Over time, the tick noise increased in volume and became more of a knocking noise. The vehicle was taken to a certified mechanic who diagnosed that the cam shaft, rods, and lifters needed be replaced. The vehicle was not repaired. When the vehicle began to make the ticking noise, the check engine warning light and several other warning lights illuminated. The manufacturer was made aware of the issue and the contact was directed to the federal safety agency. The approximate failure mileage was 130,000.

Vehicle has difficulty starting with key after sitting for 6-8 hours. Problem is less frequent when using factory remote start. Starter will engage, but engine response is sluggish. Sometimes engine will not turn over at all, other times the engine engages, but does so very rough and continues with a rough idle for about 1 minute. Once running, the engine performs as normal and subsequent starts are generally smooth and trouble-free.

I am disappointed with gm for first time ever. I had a 01 that I got 350,000 miles on it and it had all original parts. Then I buy a 08 and I have oil leaks four wheel drive light on my engine runs rough and my air bag light is on. I don't get it and trust me I just saw a website with the same complaints about what I have when is gm going to say oh [xxx] we have issues with this year maybe we should do something about it . If nothing comes about this I will be going ford and tell gm to pack sand I have driven gm my whole life and would like to stay but I have owned this truck for only a year and hoping gmc opens there eyes. *tr information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

Truck engine completely shut off while driving in normal traffic. Coasted to side of the road and restarted the truck. Check engine light was on solid. Took to a chevrolet dealer who refused to work on it but told me the 3 codes showing related to the camshaft. Drove the truck home and it felt like it was misfiring as it was jerking around the entire time. Chevrolet had it towed to another dealer who said, again, there is nothing wrong. Told them this is a clear safety issue and the dealers are just clearing the codes because they do not want to take on the warranty work. Awaiting resolution from general motors. They told me for now, I just need to drive it until it happens again.
