Merged four nearly-duplicate threads into one thread. Please do not start multiple threads for the same issue. Also, please start threads in the relevant forum. None of these four threads were started in the GMC/Chevrolet Truck/SUV forum where ONE SINGLE THREAD FOR THIS ISSUE should have been started. Please refer to https://www.gmforum.com/introduction...-first-304557/ for more details.

Post #1 was originally located in Chevrolet at this location: https://www.gmforum.com/chevrolet-17...n-ntsa-315408/
Post #2 was originally located in Cadillac at this location: https://www.gmforum.com/cadillac-174...-issue-315409/
Post #3 was originally located in Buick at this location: https://www.gmforum.com/buick-172/sa...-issue-315410/
Post #4 was originally located in Oldsmobile at this location: https://www.gmforum.com/oldsmobile-1...issues-315412/

Thankfully, the robots caught you doing this, decided it was spam or somesuch, and started auto-moderating your posts.

Here'* the deal: I could happily give infractions or ban users that do this, however, we are a forum that genuinely want to help. I see you are a new user, having only joined 744 minutes ago as I type this, so it is likely that you don't know the rules. The issue you present appears to be an actual issue, not a veiled advertisement, so I suspect you are not acting as a spammer/scammer/etc. in this effort. I have chosen to take this as an opportunity to set an example of what to do and not to do as well as an opportunity to help with your issue while educating others who might see this thread.

Welcome aboard!

I have examined all four posts. They all appear to be approximately the same as one another except for one difference:

Post #1 is slightly different than the others, but none of the differences seem consequential.

I also voted in the poll, but only after adding a fourth choice.

Now for the actual issue:

How many miles have you owned it?

Was it ever a fleet vehicle?

Is it under any sort of warranty?

What engine does it have?

Could you post the recall information for the Tahoe?

Sounds like the brake booster stopped working.

What was/were the code(*)?

What is your background as a mechanic?

Since you are a mechanic, I'm sure you got a second opinion on this expensive diagnosis that you don't agree with, right?

Did this fix the issue immediately under repeated tests in the same conditions as when the problem occurred?

Did they actually say that they didn't care?

Did they fix it immediately before calling you or did they fix it days earlier then test drive it a lot?

What was/were the code(*)?

Did the brakes do the same thing again?

What were they?

Completely makes sense, except for the price. The brake pad wear monitor uses a sensor combined with estimates of brake pad wear based on how the vehicle is used. If you swap the computer that has been tracking this, that history goes with it. It doesn't have an option to tell it to start with a certain amount of wear already, just like the oil life monitor doesn't have an option to set it to anything but 100%. This is not a problem at all and is a reasonable result of the repair performed. The price to replace all pads seems ridiculous to me.

So, the problem is fixed, and all codes are gone? Some amount of payment appears to be in order then. You don't expect all of that for free, do you?

I understand it is inconvenient to have a problem, and that sometimes fixing one problem might lead to another problem, but that'* the nature of used cars. New cars too, for that matter . . . just the warranty usually covers costs on new car problems.

So Roger is trying to get you more of a discount?

. . . and after apparently fixing your issues and getting you a 21% discount, Roger tries to get you more of a discount you call their service incompetent?

The math: $3,000.00 + $750.00 = $3,750.00 * 21% = $800.00

This assumes that GM=bad and some number of other manufacturers =good and that you'll choose a different manufacturer and they will be an "=good" manufacturer . . . based on . . . how will you guarantee this?

They all have various problems, and used cars are generally supported the same way as you have described above.

In the same class as your Suburban, your choices are the GMC Yukon XL, Cadillac Escalade ESV, and Ford Expedition Max. The GMC and Cadillac are the same thing as your Suburban in this regard. The Expedition has its own issues. Then what do you do when you abandon GM and Ford? I guess you'll have to downsize to a Jeep Wagoneer or maybe an Armada or Sequoia. All of which have their own problems as well, especially on the used market.

Why?

. . . or should I blindly change manufacturer loyalty because briknows told me to? What if I change to Ford, and I have harsh shifting from their 10-speed automatic? Will you somehow help me out with that? Maybe pay to get me over to Toyota so I can have their Sequoia'* engine fail because of machining debris left in the engine during manufacturing? . . . or maybe Nissan so I can have their Armada'* transmission fail?

I've had a few [bad experiences] with GM vehicles, but that'* because I've owned them all my life. I've documented a lot of them here at GMForum. I've also dealt with countless [bad experiences] with all other mainstream manufacturers. If I had owned Chrysler/Dodge/Plymouth/Jeep/Eagle all my life I would have had bad experiences as well. Transmission failures mostly. No amount of Chrysler failures would have made GM or Ford or the others any better.

They care about as much as GM does. Any one that doesn't would get excoriated by their competition, and their stats would be such that they'd get investigated much more than the others. I don't see that happening to any of them at this time.

No we won't. You should not have done that, and I have consolidated all of your posts in this thread. Please read everything here: https://www.gmforum.com/introduction...-first-304557/

Oh and you forgot Buick, where I found Post #3 before I consolidated.

Thank you!
