Just bought this 2017 Suburban Premier and having Transmission Problem

Manmuchwano · May 20, 2017

I took it in for service yesterday and I went for a spin with the transmission service head tech. It hit so hard from reverse to drive that he joked about it saying he didn't feel anything. And told me. To a bring it back Monday night so he can look at it Tuesday morning otherwise it was just gonna sit at the dealer over the weekend and he don't work Monday. So I guess we'll see what he says

And I drove another one on the lot. Didn't have not one issue at all everything worked fine

Also have a problem now that the engine feels likes it's miss firining after I drive it for a while. At a red light completely stopped car feels like it's miss firing. And my rear blower motor for heat/act is making a crazy loud noise.

Refer your dealer to the following TSB's:

#PIP5446: Harsh Shift 1/2 and 2/3 and Sputter Applying Throttle Between 0 and 30% Rough idle P0101 P0171 P0172 P0174 P0175

#16-NA-019: Information on Transmission Adaptive Functions and Correcting Low Mileage Harsh Shifts, Slips, or Flares

Given you are having idling issues as well.. I'd put more focus on the first one.

. Please explain what does all of that mean I'm a noob when it comes to that stuff above you quoted so I can tell them I dropped it off yesterday and the tech call me said they needed to update the computer for the mods fire (sure they did probably didn't wanna say I had a burnt wire or something) and the same for the trans.

Let me pause and ask... what mods? You didn't mention mods in the previous posts.

. I don't have any performance mods if that's what your asking. I only changed the wheels and tires truck originally gave with 20 dealer put 22's on it and had to re program the computer for the tire size. And the first time I took it in for service after about a week of owning it because trans was acting up. They had to update the trans mission. But as far as mods truck is bone stock not even a air filter or anything Just wheels n tires

Here are the TSBs I referenced earlier. I'm not sure it's the solution but regardless, information on the topic for your vehicle that was similar to how you explained.

Hey guys so here's a update I took my SUV in for service the trans guys did feel what I was talking about. I called Gm and told them the problems I had and they was looking into a buy back law. For me. But before Gm called me back The dealer called me and told me they found a engine miss fire code. But after Gm called the dealer they said no such thing ever happened and that this SUV never had a check engine light on before. Which is a lie because I got bad gas at a pump before 87 octane was actually e85 anyway they said there was no problems with the engine or trans. But now the engine doesn't miss fire anymore and the trans don't slip. I believe they fixed it on the sneak and didn't tell Gm about it so they don't take a lost. Also my gas mileage went from 15 highway. To 20 in the city go figure they didn't wanna loose money so they just fixed it. I'm just happy it's okay now... but I don't like because they lied to me gotta love honest people at Gm and dealers

That's a very flaky dealer, but at the end of the day you're only concerned with your truck being fixed.

This is what could happen to your new Chevrolet Suburban Premier. I’ve owned a 2011 and 2016 Suburban LTZ. I’ve also owned two 2018 Suburbans but I was never prepared for what happened to my 2018 Chevrolet Suburban Premier.

I purchased a used 2018 Chevrolet Suburban Premier and the engine went out after a little over 100K miles. I understand that it is out of warranty based on miles, but since it’s a one-year-old car I reach out to GM leadership for some assistance. I sent an email to Mary Bara and all the VP listed on their website to get some form of assistance but GM flatly refused. Here are some of their excuses for not offering any assistance. (1) I did not purchase it from a Chevy dealer, (2) the vehicle is registered in a business instead of personal, (3) the vehicle was bought used and was a rental vehicle or some other ridiculous excuse, therefore I’m on my own.

It’s very disappointing that a $65K car, which I always service at a GM dealership monthly, needs an engine after 100K miles. I told them I would never buy another GM vehicle. If it were a company that purchases large quantities of their vehicles they probably would do something. Big companies don’t need assistance; a small guy like me is more in need of their assistance. It’s costing me well over $7000.00 to replace the engine at a Chevrolet dealership.

Did you do a pre-purchase inspection? A used car is ALWAYS rolling the dice unless you know the owner (family, friend, coworker, etc).

100k miles on an 18 is a shit ton of miles even for a rental. Sounds like its been run into the ground - how much of that was towing? You really think it had 10-12 oil changes in the year? You are 64k out of warranty (almost triple miles), and you think GM is being unfair to you? You had 4 other burbs, how many miles you get out of them?

Hey man i wanted to discuss this issue with you. Hit me up on here. New to this forum so not sure if you can DM or anything like that.

Mikey999 · December 12, 2020

You bought used, and 1st question that should come to mind is how was this car previously used and what was done to vehicle before you. Gm pulled up quite the history on it ,and rental use . The rental use is most concerning and is unpredictable as no one knows what rentees did to it. As another user put its a roll of the dice. There were probably flags to the prior owners that motivated them to sell it. I had friend who never changed his oil once because he never intended keep the vehicle that long. I empathize with you in this situation. You may want seek some legal advice if your out $64000

We just had to have our transmission rebuilt on our 2017 Chevrolet Suburban premier at 67,000 miles. It was slipping and slow to accelerate. Going down the highway it would get stuck at 4,000 RPMs and stay there for 30 seconds or more. Thankfully we purchased an extended power train warranty and it was covered 100%. Does anyone know how long the life expectancy of a rebuilt transmission is to last? Also, we just purchased this vehicle in November of 2021 and only put 3,000 miles on it before having to get the transmission rebuilt.
