On friday, I had my vehicle in service for a failed ORC module. During the service visit, they did the recall for the the brake booster, listed a parts kit used. I don't have that parts kit number on me now. Anyway, I have noticed that I now have an audible squeaking rubbing sound when the break pedal is depressed, also when making turns, all at low speeds. Question, what did they do for the recall, anything I can look at before I bring it in? I also noticed that my brake pedal feels alot stiffer when the car is off than it was before. So much so, I have failed to start the car several times now because I have not put enough force on the brake pedal to make up the logic for the start sequence.

There were two recalls for my wife's 2012 GC brakes. One was a software update and it changed the feel of the brake pedal for the better (not as soft). The other was the brake booster. They check to make sure it isn't rotted and pressure test it. If it is, the whole booster is replaced. If its in good condition the fix is a simple foam piece that goes around to shield the seam of the brake booster (which is what we had). Maybe air got into the system if they pressure tested/replaced yours?

I would go through the steps for reassembly and see if the missed something obvious. The first thing that popped into mind was step 26. It sounds like the vacuum is bleeding off way too quickly after the engine is turned off.

Also pay particular attention to steps 9 through 12 under test brake booster.

Bill, thanks for that link, I printed it out and will check what you suggested. How the pedal feels when the car is off, is very differnet than before the work was done. Why would it be making a noise when I am turning the steering wheel? Maybe something is rubbing the steering shaft in the engine bay?

I'm thinking something either did get reinstalled, or didn't get reinstalled properly and came loose.The hard pedal with the car off IIRC is caused by low vacuum. If the hose is loose it could still work with the engine running, but bleed off pretty quickly when the engine is turned off.

Car is garage kept, just turned a year old with 11k on it. Visually, I can see no corrosion on it, but more importantly everything was working just fine, before I brought it to them. Ironically, they did not even tell me they were doing this recall. I was in to get my ORC module replaced, and did not tell them to do the recall, cause I did not want eight things done on my car at once. I just wanted the airbag, seatbelt, phone service lights to stop blinking. Now I have another problem:mad::mad::mad::mad::mad::mad::mad::mad::mad::mad:

I took my jeep in for the brake booster recall.
When they were done with it I had no brakes so they ordered a new master cylinder they could not
Find one locally . Now here I get to spend the 4th of July weekend using a really bad smelling dealer loaned vehicle a
Dodge van.

WOW jinksnyou,

Sounds just like my week. I live in So Cal and took my 2012 Grand Cherokee in this week for a couple small service items and to have the brake booster checked. The service manager told me the booster would only be a problem if I lived in Antarctica but they would take a look and most likely repair it in case I ever sold to someone in a cold climate. He came back two hours later and told me that the Master Cylinder was leaking, they did not have a master cylinder and there was no way they could let me drive that car home. They sent me over to Enterprise to pick up a Chrysler 200, at their expense. They called me back two days later on Thursday and told me they "hope" to have the part in next week. I now get to spend July 4th weekend with the Chrysler 200. Sounds like there may be more going here than meets the eye......

My appt. is on Monday morning. I hope they did not screw anything up they can't fix. I am suppose to leave on a camping trip Monday, and am already delaying the departure time. If they screwed up the master cylinder, I can't imagine they would have one of those ready. All I can see is that they did put the hokey foam ring around the seem, although the tabs are not at 3-9 o'clock as it says in the directions, and they did not remove the backing from the adhesive on the tabs to stick it down. Unfortunately, I can't see anything else unless I start taking things off, and I'm not there yet.

Really wandering how this is causing this creaking noise, when I hit the brakes or turn. I only hear it at intersections when I am coming to a stop, and pulling away turning. At a stop with the car running, when I pump the brakes it is making a pumping noise, but it does not seem to do anything, I can get the pedal almost to the floor, if I stop for a second. This combined with the fact that with the car not running the brake pedal is a rock has me concerned. I need to get to Monday or I will drive myself crazy looking at this.

I told them last week it failed they said they didn't have booster and will get me a rental after inspection. Today they clerk went to check with tech on status as its a 15 min test. Came back to me said sorry for wait the booster being replaced. When I asked how If they out of stock. She said they are allowed 3 max boosters in stock due to demand and they are only for those who failed test. Ud yours corroded but working they will put you on waiting list. The biggest danger is cold freezing weather so I can kinda see the logic albeit not the best

Just received a call from the dealer. The have a line on a new master cylinder and it may come in as early as next week. Looks like I am going to be in the rental car for at least 3 weeks. This sucks and we should get some sort of compensation for this hassle! Someone should look into a class action suit.

I don't think a lawsuit is needed, I just want my 2013 Jeep Grand Cherokee TrailHawk 5.7 Hemi and the sooner the better !! Last Wed. When I took my Jeep in for this recall and the problem happened. The dealer gave me a loaner vehicle. I didn't think to much about it at the time but this vehicle (Dodge Van) stunk like someone was one heck of a chain smoker and there was trash all over inside this vehicle. I didn't want to say anything because I figured I would begetting my Jeep back in a couple days......"NOT".... Went clear on through the July 4th weekend I didn't drive it because of the smell and filth inside. I finally went into the dealer today to check on my Jeep because they never called me one way or the other and at this point I told them I needed another loaner vehicle. Well I was offered another Dodge van which was not quite as smelly and filthy as the one I had. So I drove it home did a total vacuum job inside wiped the dash and all the trim also cleaned all the door jams cleaned all the window inside sprayed car freshener inside really thick closed her up and letter bake in the heat of the sun. Think I should hand them a bill for services rendered ?.......NOT........All I am doing is trying to keep busy till they get my Jeep done because I believe they are doing all they can.

I think, when you bring it in, and they see you have a recall, they have the parts, they are gonna do it. I did not ask for mine to be done, I actually did not want the work done, because they were replacing the ORC module. That was enough work for me at one time. Unfortunately they did it and caused a problem. I would ask, but they maybe required to do it.

I wish I had waited for awhile so these certified mechanics could of had some on hands experience. My other half said she was going to wait awhile before she gets an appointment for hers to be done. From what I gather the braking problem happens when moisture gets drawn in around the rusted area into the braking system and then freezes is when you have a big problem. So I take it as get it done before it gets down around freezing. I just wanted to hurry up and get it done and this is what happened to me. I wish better luck to the rest of you.

They must be ripping your MC out before pumping the brakes down till vacumm is lost with engine off. The service bulletin specifically says to in order to avoid damage to the master cylinder. On another note when I was diagnosing my booster/vac lines/check valves/MC it was over holiday weekend I wanted to fix it so I could just go out. I priced out a MC/brake booster from auto zone I happened to google their PN for master cylinder for their brand have to double check before I post but when I googled the MC on if I recall I read the Cadillac uses same MC. I'll look into it see if it matches...would be funny if GM has a whole cache of them

Well I guess it paid off contacting Chrysler/Jeep Customer Service. I got a call from my dealer and my Jeep was done and I could come and get it so I went straight there and picked it up. While I was there I was shown a document that said from this point forward that parts are going to be top level priority and get them out to the dealers and get these vehicles back to there customers and back on the road. You know when I called Customer Service the lady was so very nice and concerned about my problem that even I had to act like a gentleman and it obviously paid off. So if you have to call in just be nice and they will do the best they can for you. So Good Luck to all !!

On Friday, I had mine back to the dealer, walked in and said I have an appt. I believe it has something to do with the brake booster recall work you did last week. The service manager overheard me, took my keys and walked out with me to my car. He sat in it until he heard my concern, took like 10 seconds. He dropped me off, and he took my car away. 1/2 hour later he was back and the car was fixed. It appears that when they put everything back together, a mounting bracket for the master cylinder or braked booster was not mounted properly and was rubbing against something every time I hit the brakes. It even did it when the body would sway. He took care of me right away, but I also think he saved himself some hassle, because I don't think this service visit was documented, it would have gone down as rework. He just handed me the keys back apologized for having to come back, said he talked to the service technician so this would not happen again. Hopefully my master cylinder will not fail in another week, sorry for everybody having that issue.

From the press release. Can't wait to see what a mess they will make doing this


In the interest of protecting our customers, this spacer will be installed in all vehicles within the range, regardless of whether or not the vanity mirror and/or headliner have been serviced.
