We have an RDX in the family now, and after 6 months and 2,700 miles which isn't alot we have had a ton of problems with the brake system light coming on. The dealer has replaced several parts to try and fix this problem, it seems to work for a while then the system light seems to come back on. Anyone else with this problem? Also to note this is about the 4th time now.

 

what exactly did they replace? List them all and we'll see whats going on.

 

First time: replaced the Check Valves on the Brake boosters...

2nd: Parking Brake switch...

3rd: found nothing

4th: found nothing "light went off"

5th: Replaced the booster asbmly


If it goes on again this will be the last payment I make on the car cuz I'm going to trade it in or lemon law it...

I'm good thanks, trust me its not the first time I've had Acura take a car back.

 

did they and you check your brake fluid level?

 

I would think it's a vacuum problem, possibly with the electric pump.Hopefully they fixed it.

The light is back on "say good bye old woman"

 

Just sent you a PM with the info. In My Wife's RDX, the problem was solved after they repaleced the MAP sensor.

I'm going to file a lemon law on the car, this has gone on too long now.

 

If that's the case, I would quit by Honda products if I were you.

 

did you see if it could be the software update sonomaa posted?

 

It could happen to any car make, doesn't mean I'dstop buying Acuras.

 

If thats it why don't they know about it. thats not right, they have torn apart the car now. thats not right with only 3K on it and beening 6 months owned

 

time to find a new dealership/service shop if they don't know about simple tsb's.

 

Well I think they did the computer service upgrade, my problem is something else. they have been a good dealer so far no real problems, at times they are a little pissy about giving out loaners.

 

I experienced the same thing as you. Dealer reflashed the software and the problem persisted. For some reason they decided to run some test on the MAP sensor. They found irregular readings and decided to repalce it. Strangely enough by replacing the MAP they fixed the Brake System Light Problem.

I'm going to look for the service records to see if they listed somekind of code or something that might help.

William

 

They have a had the car for almost 2 yeeks now, its still not fixed. sorry I ment to give you guys an update but didn't really have anything to report.

 

Well i picked up the car Monday after work, only to take it back Tuesday afternoon with the Brake system light on again! When i got it back Monday they told me they replaced the other check valves. They also put over 300 miles on it while they had it! well its now Friday and I picked it up again after work this time they replaced the computer system. lets see how it goes. Even so I'm going to lemon law it, they have just riped it apart too much for me. it also only has 3500 miles on it and its 6 months old. Thats too much work to have done on a car so new.

 

Well its monday again, and I hate to report that the light is on again! gee maybe they will replace a knob on the radio and see if that works duh duh duh!
