2017 5.3L/8 speed lugging at throttle tip in

March 15, 2018

What really chaps my butt is GM knows they have the issue and are just sitting on their asses not even trying to correct it. I would be reasonably satisfied if they would at least admit the issue exists and tell me they are working on a solution. I really would prefer to not get rid of this truck either but I don’t know if I can take it much longer.

No update. Currently on a business trip. Will be scheduling when I return next week although now I don’t know if I should bother.

I would still make them go through it. If you can get the condition to improve, you’ve demonstrated a condition exists. Will help any future arguments.

I am right there with you. I spoke to GM yesterday reopening my case with them. They are dispatching a quality person and an engineer supposedly. I told them I just want out of the truck and that I’d like to see some options from them. The truck goes in tomorrow (Friday) because no loaners were available.

I get to drive it all day today, and by the end of the day I will most certainly be chapped. Very irritating to be in a vehicle the studders every time you try to accelerate or maintain speed.

Update:

Dropped off the truck yesterday. I have asked the dealer and GM to buy it back and/or present another offer or I am starting legal proceedings for lemon law. I have wasted way too much time on this and need to move on. If they try to just do another set of injectors I am going to lose my mind. That is a symptom of a bigger problem.

Update:

Dealer feels issue. They don’t know what to do, and GM has requested a data log. They don’t know what is wrong either. Dealer gave me a absolute BS “trade” value offer. I am meeting with the general manager tomorrow. I want out of this thing quickly. Absolutely worst vehicle experience of my life.

That completely sucks. They checked injectors on mine yesterday. Injectors flowed less than 5% difference between all of them. Does not look like injector problem on mine. Ambient air temp was just over 50F on Monday and there was no fish bite symptom at all when I drove it home from work. Ambient air temp cooled off today back in the upper 30’s/ low 40’s and like clockwork fish bite returned. Not sure what to do next. Such a pain in the butt. I’m 40 yrs old and owned Chevrolet/GM my entire life. This is the biggest POS I’ve ever had. Burns my butt they won’t admit the issue and work on a fix.

Sorry to hear it wasn’t any help for you... at least you are onto something on the temperature. Meanwhile, I was not able to reach a mutually acceptable resolution with the dealer general manager today and have consulted with a lemon law attorney. They are reviewing my documentation and determining if a have a case or not. Initial review, they believe that I do. Will keep updating as much as I can. Hopefully this thread will help other people down the road.

Update:

Datalog sent to GM, they don’t see any issues so they are sending a field service engineer.

I fully expect to hear the BS answer that it’s operating within design parameters. They won’t let me be part of the review with the GM person.

No word from the lawyer yet.

Any update on your case yet?

The GM engineer couldn’t find anything yesterday and is coming back next Tuesday to continue review.

It has been out of service for 38 days total and counting.

I consulted with an attorney and have sent GM a last chance repair certified letter so I can proceed with a lemon law case. I gave the dealer every chance to get me into a different truck, but they won’t take any financial hit to help me, so I have no choice. I paid $53k after rebates and they will only give me $40k. Kills me, because I love the truck, but I can’t have a vehicle like this. I’m out of compliance on my work stipend reimbursement, mileage, etc. It’s a mess.

I am totally amazed you have got as far as you have, I have the clunky transmission problem and called GM direct and filled a case with them. Got a call back from a girl with technical knowledge of someone who works at McDonald's. I was told the dealership has already worked on your truck and determined that is a normal characteristic and nothing could be done. I spoke with 2 different service managers from 2 different dealerships who offered to look at it but warned me there was probably nothing they could do. I am assuming getting the lawyer helped your case, I guess you have to foot that bill if you lose and GM/judge doesn't see it your way? The only reason I didn't call a lawyer is because no one seems to be able to prove any of these issues qualify for the lemon law. I really hope you win your case and once done would love the name of the lawyer you used to get one with experience on dealing with these motor/transmission issues. Thank you for all your post and i wish you the best of luck.

I hope you get the resolution you are looking for and deserve. I have also thought about lemon law on mine but with temperatures getting warmer (above 50F) the problem is becoming more intermittent. My concern is if someone needs to validate what I am feeling and they show up on a “warm” day they are not going to feel any problems. Not sure what do at this point.

I have also called GM and received he same support as you. I have also had mine a 2 different dealerships both of them witnessed and problem and agree it’s not right but there is nothing they can do with it. The fix needs to come from wishing GM and I highly doubt anyone cares anymore with the release on the new 2019 models.

Quite honestly, I am amazed as well. But, I am not out of the woods yet. If this GM engineer says it’s normal, then I have a problem. Luckily with Michigan laws, gm has to foot the legal bill if I win. The lawyer won’t take the case unless it is a solid one; only way they get paid. The biggest thing I have going for me was the fact that they fixed it once, tons of documentation. I was ready to walk away if the dealer gave me $45k, or worked out a deal to get me a 18’, but they chose to flip me the bird. Now I have nothing to lose but to try to get a win, and all of my money back. I will keep on posting what happens.

It sounds to me that a tune may fix your issue.... but otherwise, just keep trying to nail down how to repeat and don’t let them do the test driving, insist you ride with the tech. Might have to wait until cold season again, although I hear April is not going to be a warm one.
