Last fall I purchased a new 2017 Silverado High Country with the 6.2 engine and 8 speed transmission from a dealer in central Florida. It now has 6000 miles. I’m hoping that someone is having similar problems and can help. This truck hesitates and surges all the time whether its shifting or in between shifts. Its not the V4/V8 although it seems to go in and out of V4/V8 a lot. When it does it surges quit a bit. The engine is running smooth and the trans. shifts strong but this inconsistent hesitation/surge is very annoying. Its like an orifice is clogged. I can feel it while pulling a trailer at 70 mph. The dealer has flushed the trans. per the S.B.. I took it in for the second time and they say they cannot duplicate my complaint. Some times it is worst than others. Last time I was at the dealer I test drove another truck of the same model and it did nothing even similar. I called Chevrolet with no help. They said I had to go thru the dealer. I have always owned Chevrolet trucks. I’ve rented a lot of vehicles over the years and this is by far the worst vehicle I have ever driven. Other than this problem the truck is great! Please respond if you are having a similar problem. Other than taking it back or going to another dealer I’m lost and very unhappy with Chevrolet.

Hey, I have a 2017 Silverado LTZ 6.2 crewcab. It just yesterday started to Lurch forward just as it was about to rock to a stop. First time i was in middle of town and i had just pulled to a stop at a three way intersection and it felt like someone hit me from behind and lurched me forward a foot or two. It happened as it stopped and was going to rock back like the good ole popo wants you to do. I seriously thought i had been hit. Next time it happened was at end of day after driving it for hours getting orders at places with no issues. I pulled into our lot and was going to back in and it lurched again as i stopped and was about to put it in reverse. Actually lurched onto the lawn at end of driveway. There is no doubt if i had been behind someone i would have hit them. I called my dealership and they have never heard of such a thing of course and of all things cannot get me in until next week. So i have to risk hitting people for 5 days because of some crazy ass glitch going on….anyone else having this situation? I had the shudder with my last truck. The dealer told me it was the v4-v8 switching thing and did nothing. It was starting to slip so i traded it in against my better judgement for another chevy. Almost bought a Toyota but the plow switch would have cost me 6 grand more……

I just purchased a 2017 1500 with the 5.3l and I am also experiencing the same problem. It has serious hesitation when accelerating at slower speeds. I have not done a whole lot of highway driving yet so I cant say to that yet but I am praying there is a simple fix for this. I hate to think I just spent 60k on my dream truck and am going to regret it.

JamesCooley and Bgup44,
I am experiencing the same thing with my new 2000 mile truck. Its at dealership and the Service advisor, manager and tech all stated that there is an issue with what appears to be the gas pedal by wire system. They have driven my truck and a similar truck (the exact same truck) and found that the gas pedal is harder to push and that the shifting RPM is effected by it BUT GM is saying because theres no codes theres nothing wrong and is making them try all kinds of stuff except the 3 that makes sense, Re-flash entire PCM then reinstall the recall released on 8-14-2017 regarding the transmission. Doing this may reset the very reliable gas by wire system considering its either the computer, sensor or throttle body (only 3 items it can be)
Ive spoken to GM care and they are a joke, It is not the same GM from years ago that actually cared about what was being said, They try to push off or passify you in order to get you to give up.

My “throttle-by-wire” car had a similar issue; however, it would keep accelerating then decelerating… “vrooom…. vrooom…. vrooom…”. Like it wanted to race the care next to me.
First time it happened, I was in a drive- through… while trying to figure out what was happening, I put the car in park…. the manager came out to ask me “what my problem was…” (thinking I was being a jerk). I got out of the car, and it sat there by itself in park. — Vroom… vroom… vroom…! I turned the key off, and restarted – it was fine for about a week.
Next, it happened in stop & go traffic… typical of an intermittent problem, the dealer couldn’t do anything.
It finally happened in my own driveway, and I let it just sit there… vroom… vroom… until someone from the dealer showed up… they were too afraid to drive it, and towed it away.
After roughly 3 months and lots of arguments, the dealer took the car back.
My next car did not have “drive by wire”…
