Interesting they were happy to let you wait 6000 miles, in the UK the official letter we had from Mercedes forbid us from driving the vehicle, from the date of getting the letter ,until it had been checked by the technicians.
however I did ask the guys that came to check my car about back log of parts needed and he did say they were not able to get the required parts until end of August / September.
if my car has failed the check up the they were due to remove the car on a transporter to their premises until the parts arrive, so several months with no car !
I read on a Mercedes’ group that someone mentioned he was not offered a courtesy car but was offered £30 a day compensation , this could hit £3000 ! If this was correct !
apparently in the UK they have 300000 vehicles to check.

I had my 2011 ML350 Bluetec Brake Booster checked today....unfortunately it needs to be replaced and they have no idea when the parts will be in......So now we wait for the EGR value and the Brake Booster. They offered $80/day toward a rental...I would have to pay upfront and they would reimburse. I haven't been driving the POS anyway so don't need the rental headache. Wish they would just buy it back. What happens if the EGR isn't installed before the October deadline on the class action suit? Asked MB dealer, they don't know. Will never buy another MB...

Do you live in the rust belt?

What are all the locations that your vehicle has lived it’s life?

blt212

I live in Connecticut....I am the second owner and I'm pretty sure the first one also lived in CT. I bought it from a dealer so not positive. I also spend part of the winter in Florida and the ML didn't even get driven that often in the snow....

91stealthes

Interesting. Did they give you any photos you could share?

My vehicle spent 2 years in Florida, 3 years in Illinois winters and 5 years in New York winters. I wonder what they’ll have to say when it goes in.

blt212

Sorry I didn't get any photos.....my husband was surprised though that it failed because he looked under the rubber sleeve and didn't see any rust so it must not have been visible until it was cut off...

You are always complaining about the reliability of the latest Mercedes.

Hopefully now you realize Mercedes has always been junk.

Max Blast

we wouldn’t be here if we thought so.
but they have been progressively more complex and less reliable.

Your 2021 GLE will never make it to 183k miles like my 2008 has.

For those that have had this done, what can I expect? Do they remove the brake booster? Do they remove the “boot” on the booster? If so, do they put a new one on? Wondering how long it will be in and what to expect when getting back.

It’s about a week now I have my rental vehicle but as of yet I have not heard anything from Mercedes as to when they will check my truck or replace the brake booster if needed so. I’m actually driving an Audi Q7 now I have to say it is a nice vehicle

blt212

Just got a call from the dealer and they said corporate just gave them approval to do a second test on the brakes, something to do with a vacuum....anyone else hearing something similar from their dealer. Interesting this is coming a day after the Brake Booster Class Action was announced.

Pmanc

I actually called Ray Catena in Edison and I have an appointment in two weeks I’m supposed to have the car towed I am not supposed to drive it and then they will take it from there.

I find the brake recall confusing and it’s importance. I was told by Henry my service representative at Mercedes Benz of Modesto Ca. not to worry about the recall and to bring my 2012 GL350 in at its next service to have the brakes checked at approximately 6,000 miles.
Go figure!

Again, this whole issue was pretty badly handled in it’s inception, promulgation and execution by MB.

Unless you feel something wrong with your brakes, or a visual inspection reveals massive amounts of corrosion on the brake booster, you’re all educated adults capable of making the appropriate risk decisions such as disregarding MB’s advice and continuing to operate the vehicle.

Just had my inspection done by MB of Buckhead in Atlanta. Massive amount of corrosion on the sleeve, and the first test failed -- but they did a 2nd test that passed, and went on their way. Total bull**** -- now I get to white-knuckle my way around town praying my brakes decide to continue working.

Is the approach "test till a pass result is achieved"? I doubt it, but it's worth discussing with the service manager of the dealership politely (not the service advisor). Find out why they did not take the fail resilt and performed a second test. Or did you ask the techs about it? Also, ask how many fail results are necessary for them to accept a fail. Obviously a pass trumps previous fail(s) and one pass is sufficient.

Did they record the fail result? I'm sure the pass is on record. I would ask for a full copy of the testing procedure and all results for your records, and do so promptly while the memory of the techs is fresh, in case they are polled by the manager. Perhaps a personal visit rather than a phone call would work some wonders in your favour.

With heavy corrosion on the outside, I would expect a prompt appointment to inspect the inside of the booster to follow. If that is not on this dealer's urgent list, I would call around other dealers and inquire about getting that done. I wouldn't bother mentioning your inquiries to other dealers to this one, personally.

So the tech that came out to me today said that they just recently updated the guidance, requiring a 2nd test if the first test fails. Prior to this week, a single failed test would require the replacement (this is also what the service campaign says).

I agree, I don’t think it’s a “keep testing until it passes” — but there’s still a significant concern if it failed at all…

expl0rer

It's hard to say without knowing what and how they are testing, if a fail result is a concern , when followed by a pass.

It would be good to also know why the guidance was updated. In any case, maybe asking the questions to your service manager would give legitimate answers.

deraj090

Good points. The problem is, I've never actually worked with this dealership before -- they just had my contact info in their records from having purchased an accessory -- but I'll give it a shot!

Or you could just preemptively replace the brake booster now that you know it will eventually fail.

were any of these two tests on a brake dynamometer?

Many European Road test stations test your car‘s break on a four wheel brake dyno to test for diminished output or uneven breaking action…

I feel as this is the smoking gun that MB should be using here unfortunately they’re not very wide spread in the United States.

deraj090

I do want to preemptively replace the booster, but I refuse to pay for it. They’re telling me that because it passed the test, I’m not eligible — is that accurate?

the two tests were the same — they just run it through the same Xentry diag twice. This is what’s ticking me off…a fail is a fail, in my mind — especially when we’re talking about a piece of the car that drastically impacts safety and is now known to fail.

blt212

From what I was told by the dealer the Brake Booster parts are not available even if they deem it should be replaced. A situation similar to the EGR valve which isn't available for the AEM install for diesels.

Or the new Takata airbag for those affected
