When ever I let off the brake, the pedal has this metal to metal clunk :( sound when the arm comes back up. I've never heard a car do this and usually there are rubber isolators and stops that cusion the brake pedal when released. My car has less than 1k miles on it. I didn't notice it the first day and can't pinpoint when it started. Has any one else noticed this noise?

Pretty sure it's right at the pedal under the dash. Even when I try to release the pedal very smoothly it still makes that noise. Guess I'm calling the dealer. I'll leave a note if it's something out of the ordinary.

Going to the dealer for the pedal issue on Tuesday June24. Now I also noticed my center console is loose on the right rear corner. Not sure how that is attached but I can rock it off the floor on that corner about 1/2". Another note to you Malibu people, I was vacuming out my Malibu just this morning. Noticed some debris inside the hand grip area of the left rear door. Stuck the vacum hose in there to suck out the dirt and pulled the little rubber screw cover pad right into the shop vac. Those are NOT fastened well at all. At least I knew where it went. What a mess getting that out. To all, have a great weekend.

Well,the tech said the pedal was "normal". I think he was testing it without the car running. I can still make it, make the noise but I guess I'll just have to watch and see what happens. I'll most likely have it back in someday and I'll have them test it while I watch. It's not like it's failing, I just never heard a pedal make that noise when released. The center console was a loose fastener and was fixed with no problem. I'll try and attach a copy of the shop ticket.

I'm experiencing something similar with my '03 GMC Envoy SLE, but it appears to be a temperature problem, since once the car's warmed up, the noise stops.

The 2LT I test drove and the LTZ I bought both make the "clunk" with the pedal when I let off the brake when I remove my foot quickly....If I let the pedal back sloooowly, then no "clunk", but under "stop and go" or "feathering" the break, the pedal does "clunk" when I remove my foot. I'm thinking I'll "live with it" ????

Finally, I'm glad I'm not the only one. Mine still "clunks" and it may be normal and not serious, but it is really annoying. I want my salesman to hear its o I'm going back to let him review the problem. I think I may even write a letter to GM to see if they can start gathering some data on complaints and come up with a cure. There has got to be some sort of adjustment or isolator they can use to eliminate the noise. Thanks knsdye for confirming my car was not the lone problem.

"live with it" might have been the wrong decision...Try this test in your driveway. Extend the telescoping steering wheel out fully, and also "tilt" it down to the maximum. Then apply the brakes and release. On each release of the brake pedal, check to see if your brake lights are still on. Do this same test with varying degrees of the adjustable pedals, from all the way out to slightly in (not sure this last part is involved, by the way)..
Here is what happened to me about half-way into a 4-hour drive on my way to visit relatives for the holiday. When leaving a rest area, I put the steering tilt out/down (it wasn't out/down like this before stopping) and got relaxed. It took long enough for things to begin to go "haywire" that I didn't correlate the problem to my steering changes, but essentially, the dealership that I limped into identified this and say they haven't seen it before. The "Service ESC" and "Service Traction" DIC messages appeared while driving, Cruise-control quit working, and RPM Tachometer would wildly fluctuate. At the dealership, the technician, showed me that the electronics thought the brakes were still engaged, as you could still see the brake lights on along with the hand-held ODP unit plugged in showed brakes still "applied"; placing the steering wheel "up" slightly eliminated the errors in the hand-held and symptoms cleared. Dealership sent us on our way and we'll get it "fixed" at home.

Mine does the same thing as above. I tried to replicate that error the user above me mentioned, and I have not had any issues with the wheel in that position; I do have it much higher than that normally however.

The "clunk" noise I think is just two pieces of rubber or similar material striking each other when you let off of the pedal; possibly to keep the pedal from going too far forward.

It is nothing to be picky about for me, all my past vehicles have been worn-in imports and they all had the same brake "clunk" so I did not even think of it as a problem :D

Well, had to come home with a "rental" car over the holiday weekend and left our baby at the dealership where we were visiting; Check engine lamp and no power accelerating from a stop, erratic shifting turned out to be a P2714 error code with the tranny in 3rd gear failsafe. "Pressure Control Solenoid 4 stuck off" I think? Our baby was performing flawlessly after the earlier brake issue was identified, but then this happened about 150 miles later. Our baby is a June08Mfg delivered July16 '08 LTZ with the 2.4L 6spd tran. GM TAC Eng want the whole trans sent to them and we're getting a new tran. I guess they want the first 50 with this kind of failure to examine? Looking at this weekend to go and get it (please, oh please!)

Car was ready for us yesterday and got back home late last night. Very nice drive 280 miles, no issues, drove great, shifted sweet thru all 6 gears, ran like new..(at least like it did during the first 500 miles (slight sarcasm :D )...interesting...There's no brake pedal "clunk" anymore. Can't seem to understand how that could be related to the work done replacing the transmission. The out-of-town dealership doing the tranny work "forgot" about the "tilt steering" / pedal issue from earlier in this whole fiasco and when I pressed them they said they'd look at it, but I balked and said I'd have it done at my home dealership. I'll try to post the final status if/when I take it in for the first oil change. Still deciding if I'll do that myself, instead. :)

WOW - Glad to hear it all worked out! Nice to see GM stepped up to the plate and replaced the whole tranny, unforunate that it was yours but atleast you have helped them to identify a problem and now they are working on a solution.

I decided to do the first oil change myself, so I haven't been to the dealer about the pedal "clunk" and C0131 error code when tilt/telescope is "down and out" as described earlier in this thread. I don't believe my transmission failure is necessarily related to this pedal "clunk" either, just coincidence.

Anyway, I noticed a recent TSB, PIC-4883A at http://www.aboutautomobile.com/TSB/2008/CHEVROLET/MALIBU

I'll try to have it checked out and post again after the New Year

Good info knsdye, as I re-created the brake pedal clunk in my 08 2LT with the steering column in full down position. When I raised it just slightly from the full down, the clunk went away. I read the TSB but is there a fix for that phenomonon? I think I call my dealer and see if they know of any fixes. On another note, as it was listed in the thread, I had the threaded insert problem on my oil pan plug. Recieved a letter, took the car in, changed the insert and got a free oil change at 5,200 miles. Still had 34% on my oil life, but it needed it anyway. Now I can safely change the oil myself from here on out.

My '08 had a clunk that i could feel in the pedal.

The dealer told me it there was a service bulletin for this, they drained/replaced the brake fluid and bled the system.

Problem gone.

Aside from a squeak that's very temperature specific, that is the only issue I've had in 8,000 miles.
