I attempted to back out of my garage this morning but the car would not budge. The emergency brake was not on but it was if it was.
Normally, I just roll backwards on the car's own power out of the garage but it would not move.
I gave it a bit of gas and then I heard a very loud clunk and then it was able to back out of the garage.
Now, when I brake going forward, I hear a loud clicking sound from the left side.
3oo miles on the odometer and then this?
My 23 BMW M340i has been rock solid since December 22.
Not a good start for me and PHXACT with our CLE 53's.
I hope I don't regret buying this car.

Welcome to MB's faulty parking brake. If your undercarriage gets wet (car wash, rain storm) the parking brake bonds itself to whatever surface it uses when engaged. Takes a bit of force to break it free. Happened to me with my new 2024 GLC. Dealer wouldn't do anything about it. Seems it's a known issue. In fact, it happened on my wife's 2023 GLE350 the other day. I drove it straight from the car wash to the garage and the next day it happened with her car. Thanks to a member here there's a workaround. Biggest problem for me is remembering it. When you're ready to shut the car down put the car in Park. Before turning off the ignition, pull the parking brake release out and hold it. Turn the car off and then let go of the release. This prevents the parking brake from engaging. When you take your foot off the brake the car will roll a bit until stopped by the driveline parking pawl. Clumsy but effective.

Thanks for the information. Unfortunately, there’s a loud ticking noise now when I step on the brake pedal going forward. That needs to be repaired. Hopefully, they get me in tomorrow before I head to NY Thursday morning.

As mentioned, it is the parking brake. Very common on MBs not sure about the clicking noise though.

I had that issue sometimes on the 18 E400. Sometimes I would hear a clunk when putting it into reverse and go. But it was never like this to the point the car wouldn’t even move. I did wash the car the other day. We’ll see what the clicking noise is.

Hope it is a simple fix, I have many occasions of having to press the gas for it to move and a loud bang, it depends on how rusty it is but this was on another MB model.

This clicking noise? https://mbworld.org/forums/cle-class...ack-cle53.html

Sorry to hear and hope it gets resolved. Title is clear, MB is pure unadulterated garbage.

Here's a vid I posted once before that I made for the dealer. It's 2 parts. First is the GoPro under the car and the second inside the cabin. The service writeup suggested that I should ride around after a car wash to dry off the brakes. Of course they did not suggest what I should do if it was raining.......

I’m sure it has to do with the brakes. Your attachment above doesn’t seem like clicking issue from the brakes.

You don’t expect to hear such noises from a car. At least you managed to move your vehicle. I really pressed on the gas to force it. I definitely broke something forcing it to move.

I experienced a similar effect last week after hosing off my wheels and then immediately pulling forward and parking in the garage. The next day I attempted to back out, and there was a sudden pop before the G550 moved. Guess I'll drive a couple hundred yards and dry the rotors off in the future.

Sounds like crap when it happens, but generally harmless. I could see the rust where the pad held during parking. Just a nice hard brake the first go around and all clean and clear. Obviously most common when parking after rain. If you’re worried just disengage the parking brake after a rain fall.

I have to make the parking brake release part of my habit pattern on start and shutdown.

Happened to me a few days ago on my brand new 53 , also after parking after a car wash.

So, drove the CLE53 home in the rain and parked in the garage until today, when, after reading this, went out to see what it would do. And CLUNK is what it did after giving it a little juice to get out of the garage, backwards. Nothing else other than that, so to me, normal operating procedure. Our 911 did it as well. Our Cayenne does not do it, although it has the PSCB (quasi ceramic brakes).

I agree, it is a bit unnerving and seemingly something that one should not have to worry about or experience at this day and age of cars. Seems kind of silly that rust would form on the rotor/caliper assembly or the P brake would activate after a wash, rain, or other precipitation event and being parked.

My car would literally not move unless I stepped on the gas peddle. I was very hesitant but it was the only way to get it out of the garage. The car fought me but I figured that if something broke, they'll fix it. Something did break (I don't know what) and now the left rear wheel makes clicking noises when braking going forward.

Ugh! I am sorry to hear this. I hope the break is nothing serious. I am surprised how common this seems to be.

Do folks set their emergency parking brake when the park or is the car applying it normally?

I never used my parking brake on my old C43, but now that I think of it, I recall a similar experience. Had to give my car a little acceleration when reversing for the first time (and I was frequently washing the car or spraying down the rims)

The car automatically applies the parking brake when you place it in park every time

Curious what your purpose is on this forum aside from seeking out posts of people's issues and letting everyone know how **** you think the brand is? Seriously, what is your purpose?

Nice video thanks. I experienced this parking brake issue many times on my 2019 E450 but so far never yet on my CLE53. Regarding the CLE53 have people with 6 piston calipers also suffered this problem or only the 4 piston? Just curious.

Buyer's remorse on big ticket items always cause strife and stress......GL with it

Took a chance a called Randall, my SA at MB Naples at 7:30 this morning. He answered and told me to bring it right in.
He acknowledged this clunking issue on MB vehicles. I told him about the recommendation mentioned on this thread below.
I didn't have an appointment and they gave me a loaner. Thumbs up for MB Naples Service Dept.

The noise on the video in an earlier post is disconcerting. My clunk was extremely loud as was the clunk in the video.

I've had the same issue when washing/cleaning my rims.
I've taken to using my leaf blower to removing most water/moisture and driving the car (a quick spin around the block) after that, that seemed to solve the problem.
I do believe that the rear brakes are noisy and all around somewhat sensitive to the pedal, I'm learning.
I'll bring that to the attention of the service bay, which I'm certain as stated here that they are aware of the issue and have/offer no solutions.
I find my local MB dealer is lacking, it seems the rotation for service bay advisor changes every hour, glad that the 1 or 2 of the experienced mechanics have been on board 12-20+ years.
Not very encouraging.

I use a leaf blower as well to dry the car. Obviously, did not help. Will keep trying the parking brake method mentioned earlier if I can remember. I don't expect my wife to.
