2017 GMC Sierra 1500: Surge, Hesitation, Chuggle, Misfire, Feeling wit

_{This TSB 95% fixed my issue. The torque convertor now locks up and stays locked. Before it would lock/unlock the whole time unless you downshifted. It is much better regarding drivability but still not 100% perfect. Fuel mileage increased also as now I can lug the engine to build speed rather the downshifting.}

Same here. Its not 100% but its much better.

Mine isn't fully cured either. Much better than it was, though

looks like a lot of warranty fraud going on at your dealership.

2.0 hours OLH on one line to road test and then 1.2 hours on the next line to road test. Also replacing the trans filter for no reason. (believe me, it wasn't cracked).

 

tech probably got paid 4.0 hours to fix a problem that a simple 0.3 reprogram that there's a TSB on would have fixed.

Mine had this problem pretty bad, it was very noticeable going up hill on the highway. It had this from day one, I had been following this thread; waiting for a fix to come out. But now that the update is available, my truck isn't doing this anymore, it seems to have fixed itself; I have not had any updates done or been to the dealer at all for anything.

 

So, I don't know what to do, should I go to the dealer for the update or just leave it alone?

 

I'm very happy with the truck, it's been running great lately. 2017 5.3 6 speed, about 13,000 miles on it now.

Hey as long as they got it fixed I could care less. They will get theirs if they are frauding GM.

[NEVER AGAIN A GM]

I Had my Arbitration Hearing with GMC:

 

After opening statements were given and a question and answer session finished we went for a test drive.

 

I Myself, The State Arbitration Technical Expert, GMC Attorney, GMC Field Service Engineer all went for a test ride to confirm the issues with the truck.

 

When we got back the Engineer whispered into the Attorneys' ear twice "Buy It Back", "Buy It Back"

 

The Attorney immediately then offered to have GMC by back my Truck with everything I paid to be refunded to me.

 

When we got back to the Arbitration hearing room the case was marked as we have an agreement as GMC was agreeing to buy back the Lemon Truck.

 

It took almost 3 weeks but today I finally was able to bring back the Lemon GMC Truck to the Dealer I bought it from.....

 

IT SHOULD NOT HAVE HAD TO GO THIS FAR.....GMC and the Dealership along with the Customer Assistance Center made me jump

thru hoops to finally come to a resolution on a truck that was a definite Lemon.

 

My advice to anyone who has a GM Truck like myself Do Not Settle For Anything Less Than What You Paid For.

 

If you have issues with your truck and are NOT getting help from GMC or Dealership then the Lemon Law Arbitration Does work...

 

DO NOT BE A SHEEP AND FOLLOW THE HEARD....

 

WE PAY GOOD MONEY FOR THESE TRUCKS...DO NOT BE TAKEN ADVANTAGE OF...IF IT CAN'T BE FIXED HAVE IT BOUGHT BACK...

 

Now it's time to go shopping again.... but after all of what I have been thru with GMC the Dealership and GM Customer Assistance Center.

 

Not to sure if I want a GMC truck ever again...

good luck with those "other brands"

good luck with those "other brands"

x2 It doesn't matter what brand you buy, diagnosing some problems became difficult after the late 60s when they started with all this air pollution crap and gimmicks and kludges to get better gas mileage.

 

All brands, foreign and domestic, are made with the same metal, rubber, plastic, and electronics crap programmed with a millions of lines of code, each portion written by dozens of programmers, some likely under contract in countries half way around the world, which has to interface with sensors and modules manufactured in different countries. Couple this with the fact that the identical part number sensor or module may be manufactured in multiple plants and one part in the bin may be slightly different than it's brother in the same bin. When they can't find the faulty code they generate more to try to work around it and sometimes they end up with something nobody can figure out or correct properly.....even the best QA system can't detect all cases beyond infant mortality in component/software.. .best they can hope for is to get the dog running until it is out of warranty.

 

So the question you have to ask yourself is: With this track record why do so many owners rely upon the crap routinely spewed out by the OLM as gospel? It's algorithm doesn't account for Julian date time, air quality/filter changes, brand/type/viscosity of oil used, running temperature, volume of oil in the crankcase and likely many other factors affecting oil that it presumes to generate an accurate reading of oil life. It's easy to see the results of screwed up programming when it makes the engine run like $hit.........but if the OLM readings are just as screwed up you'll never know until the engine is out of warranty and you end up with a premature failure or smoker that can't pass emissions.

im going through similar crap with my high country now. I guess im going to have to go the lemon law route.

 

I could care less what brand I drive. once one brand screws me over and wastes this much of my time, they don't deserve my business. good thing there are other brands out there. at least the ford and dodges have some balls. chevy transmission tuning from factory is a joke. takes a $600 warranty voiding tune to fix it. I cant believe people pay $50k for these sh!tboxes and find that acceptable

Same here, much better than before but not perfect. I have a noticeable clunk when decelerating as well, especially during hard braking. I don't think it's related, although it seems more pronounced after the TSB was performed.

[sonerick]

So what all is required to do the update?

 

Is it just plugging in to the OBD port and preforming an update?

 

Or do they​ have to drop the transmission pan for something? What all is involved?

 

Thanks

 

It only took the dealership I went to ~2 hours to do an oil change, rotate tires, and perform this TSB, so it doesn't seem that involved. I think they just reflash the TCM.

Thank you, I've been wondering.

 

If anyone else has more insight, please tell.
