Maybe I missed the beginning of this post but I did not see where you had the brakes inspected at 30,000 miles and at 32,000 they are metal to metal. That is an important part of the story. I would have assumed they wore evenly for 32,000 miles now they wore down from 70% to 0% in 2000 miles. Was the wear even on both rear brakes? How about the front?
Was the "mechanic guy" the Hyundai dealer or a independent mechanic?
Someone lied to you if the pads went from 70% to 0% in 2000 miles. Either the mechanic was lying to you about the 70% left statement or he screwed up your brakes. How where the brakes on the front of the car?

The Front Brake is fine.
The "mechanic guy" is the independent mechanic. he said the front brake is 50% left in 30,000 miles.

Your original post said 70%. Maybe you should be going after the independent mechanic.
If I was Hyundai I would say "So your brakes where worn to 50% in 30,000 miles and you had a non-Hyundai mechanic work/Inspect them and 2000 miles later the pads wore out. That sounds like the braking system was damaged/mis-adjusted by the independent mechanic"

If I track this failure timeline correctly the rear brakes were inspected by an independent mechanic 30K miles...pronounced to have 70% of the useable lining available at that time yet approx. 2K miles later both? rear pads were worn to the point they destroyed the rotors?? I find this to be impossible UNLESS only one side wore in that fashion which to me would indicate a caliper problem. Exactly why do you blame Hyundai since you did not see fit to return to the dealer for at least some services but instead trusted "your mechanic guy" who appears,to me at least, to be less "mechanic" than just "guy" (unless I am missing a whole lot here) then when a major problem appeared you DO go to Hyundai. Then when they tell you that an expensive repair is indicated (but won't pay for your "mechanic guy's" mistake) you start proceedings against Hyundai. I will tell you that unless a caliper stuck no car will blow through the 70% of the remaining brake lining in 2K miles. Not possible!!! If a caliper stuck there would be several symptoms not the least of which would be a drag since essentially the brake would be applied at all times on one wheel that you should have noticed when driving followed closely by the smell of burning brake material next the flames and smoke and last the grinding you finally noticed.

I find that hard to believe, too... if you went from 70% brake left, to 0% brake left, in 2K miles after it took 30K to go 30%, he just blew through 70K of brake pad in 2K miles; what kind of gas mileage did he get? 5MPG? 10MPG? If I see a drop of four MPG for two fillups without a reason, I would assume an issue with the car and would have it in the shop; he's talking gas mileage HALVING or even QUARTERING, and he just went on his merry way. I just can't see it; there would be too much indication of a problem for any driver, even a clueless one, to not say something is wrong. Since I would expect the rear brakes to wear out in 45-50K miles on a modern car, the 70% sounds VERY fishy... unless it was "70% WORN, 30% remaining". If that's the case, Haidong had a bit of bad luck (probably a stuck caliper or something) he compounded by not bothering to pay attention to the signals his car was giving him that something was wrong.

My original post said 70% left in rear brake and 50% left in front brake.
Independent mechanic only take a look at the brake. If there is no dust cover, I could take a look at by myself. the only independent mechanic is lifting my car, so we could take a look at the brake.
when people ask me about hyundai sonata "Cash for Clunkers", I told them should not consider hyundai. 2 people took my advise and buy other cars.

Although your reply was directed at "newowner10" I can't help but wonder exactly what has happened here since it has become too convoluted for me to follow. I don't believe you quite know yourself. Since Hyundai didn't respond as you believed they should have to whatever damage or failure occured to your car maybe they didn't for good reason.....Ya think??

" I don't believe you quite know yourself."
You are working for Hyundai?

The problem is that the important details come out one at a time. So with your posts mixing with other posts it is hard to get all of the details without writing them down. I think people need to be in-tune with their car when something changes you can immediately react to get it looked at.
I hear cars go by that are making all sort of noises and it appears if the car moves it is not a concern.
It was important who said the brakes were good and when.
It appears Hyundai's part was they built the car. They never said the brakes where good at 30,000 miles and had a complete failure at 32,000 miles. It is important to know if both rear brakes failed or only one side. One side would indicate a problem.
As i recall a non-Hyundai mechanic look at the brakes at 30,000 miles. This is who you should be after but his pockets are not as deep. If you want yo enter the complete story in one post people could give you an opinion.

Actually, We pay special attention to the car since most people have the bad experience with brakes. This is also the answer from Hyundai customer service, you have to let the Hyundai trained technician check the brake twice the year. Do you really spend $100 every year to check your brake?
When I heard the grinding noise, I bring the car to the dealer the first day. When I found the brake, the first thing come to my mind it that Hyundai is using the defect part (do not have the heat treatment right in the process, not right certificated material)
We should hear the noise ( warning sign) before it is gone, but it does not happen. I think this is the reason that we are not happy. Also we got all kinds of explanation.
If you check all the posts in this forum, anyone got the warning signs?
We are not the car specialist, If the car is old, we know it could be wrong. Most people buy Hyundai because it is cheap. So finally we found out it is using cheap materials and cut the manufacture process to make it cheap.
We could tell everyone that we know how bad Hyundai is. and so less and less people will buy Hyundai.
