#84 of 105 2004 CTS brake problem by car2401

Jan 31, 2012 (7:04 pm)

A few days ago my mother was pulling into a parking spot and couldn't stop. Her foot went all the way down and she could not do anything to stop the car. She ended up hitting a pole and it made some minor damage to the front bumper ( paint and a crack). The car was tested by several mechanics finding nothing wrong. However, this was a scary moment because in a different situation someone could have gotten seriously hurt. The car will be taken to the dealer to see if anything can be done to prevent this from happening again. We are hoping to get some satisfying news and feel more confident driving it again. As of right now cadillac is not looking too good with this problem remaining unsolved.

#85 of 105 ABS, brake assist and system stability 06 cts by jandi

Apr 18, 2012 (5:39 pm)

I have an 06 CTS with 75,000 miles and having issues with warning lights about ABS, TC, brake assist and system stability. I was told it was my front passenger wheel hub, replaced it and still codes were there. They diagnosed it and said software needed to be replaced. Took it to dealer n delear says the electrical module needs to be replaced. I'm very frustrated bc this should be a top of line car n has just given me problems. Same issue happened last year, but they were able to reset it. To repair is going to cost me $1500 and I've already spent $600. Does anyone know of any recalls for this vehicle?? Who can I contact about recalls? I'd appreciate any info. Thanks!

What happened to your car? Did it get fixed? I'm having the same issue and I'm worried because I have 4 small children. The front passenger hub has been replaced but codes are still there. They say it my module.

I Am having issues with my 06 CTS. Brake assist, system stability, abs and tc. Front wheel passenger hub has been replaced but no luck to codes being removed. They say its the module, but from reading these forums I've had a lot of the same issues like everyone. Is there any recalls? My car is no longer under warranty, it has 75k miles. Please help. Same issue happened last year.

If you wanted to send the last 8 digits of your VIN to socialmediagm.com, we'd be happy to check for any open recalls on your vehicle.
 
Look forward to hearing from you,

#90 of 105 the discussed failure sounds like "ABS failure" not "brake failure" by elias

May 04, 2012 (5:47 am)

If I owned a vehicle that gives symptoms like this (and I do) - I would consider to pull the ABS fuse. This will prevent the ABS system from "misfiring" at low speed. But with no ABS in some conditions it might require knowledge/sense of how/when to drive old-school by "feathering" the brake or actually manually pulsing the brake pedal when necessary.
  
My 2005 GM vehicle has had apparently the same intermittent ABS failures for years - sometimes a diagnostic failure - sometimes felt at low speed hot weather when one of the 4 brakes is released - it does increase slightly braking distance and is alarming but increasing pedal pressure does function properly.
 
For my car, the issue is basically known to be wheel speed sensor, especially when heated. It's so intermittent and imho is not safety related, because it only occurs on *one wheel* at a time. Always the same one. Right front.
I understand that in some (all?) vehicles the speed sensors are especially sensitive to damage from road debris or mild corrosions.

#91 of 105 Brake Issue by b_fishr

Aug 24, 2012 (6:49 am)

I almost crashed while pulling into a parking spot, brakes were grinding (as if ABS was freaking out) and the car would not stop ( I was going about 2mph). Finally I was able to get it to stop about 1 inch away from another vehicle. This is on a 2007 CTS. I have not taken it to a dealership yet, but I know for a fact that there are no problems with my brakes, they operate normally in other situations. The symptoms are almost exactly the same as comment #42 by j1nce. I did not get a service indicator today, but I have had it show up after restarting the car (turn off to go in store, come back to notification). Are there any recalls dealing with this issue, as it doesn't seem severe enough to produce a code, and I don't have the $2000 others have spent on a potential fix.

#92 of 105 PLEASE REPORT THIS ISSUE by coastsidefog

Aug 24, 2012 (10:54 am)

As you know from reading this thread, we had multiple replacements of our wheel hub, speed sensor, EBCM, etc. (among other parts) to try and fix the very serious problem of a car that would intermittently have its brakes fail at slow speeds (ie, in a school parking lot with children).
 
We had multiple communications (in person, via email, letters, phones) with GM during that time. GM never showed much concern about the potential liability/risk of morbidity and mortality associated with this problem. The dealership replaced the speed sensor/EBCM 4 times in an attempt to repair the problem (although it never did). We paid out of pocket quite a bit of money once the car was out of warranty, but the problem did not resolve.
 
Eventually, an intelligent mechanic fabricated a new harness with new terminal grounds from the EBCM to the left wheel speed sensor and rerouted the harness away from any possible sources of inductive voltage. Once that was complete, we have not had a problem.
 
The mechanic (who works for our dealership) said to us that anecdotally he has run into this problem more than once and that there seems to be a failure in the design or workmanship in some of the wiring harnesses connecting the EBCM to the speed sensors that causes the brakes to fail. (Separately, he recommended the next time we buy a car, we not buy a Cadillac, because he felt that the fix -- rerouting the harness -- was not a time- or money-intensive fix, but that GM didn't seem interested in letting car owners know that, despite the potential and obvious dangers).
 
We spoke with our representative to Congress who asked us to file a report to the National Highway Traffic Safety Administration (NHTSA), who with enough examples is able to force GM to notify owners or issue a recall.
 
I would STRONGLY encourage all of you who have had this problem to 1) have your mechanic check the wiring harness for sources of inductive voltage, and 2) to report the problem to your congressional representative and to the NHTSA.
 
You can find your congressional representative here: http://www.house.gov/representatives/find/
 
You can report to the NHTSA here: https://www-odi.nhtsa.dot.gov/ivoq/
 
For us, as a family with small children, this has never been about getting any reimbursement for the large amount of money we've given to attempt to fix this problem. This has always been about making sure that the cars on the road are safe (thinking about driving this car in my children's school's parking lot started this process).
 
We have been truly disappointed by what seems to be GM's lack of concern about the potential safety hazards. I try very hard to be a fair-minded person, and I have been so dismayed by GM's lack of interest in responding to these concerns. Shame on you, GM, for letting the dollar or just plain laziness stop you from getting information to car owners that could potentially prevent a serious accident.
 
Please let the NHTSA know about your issues, in the hopes that they might be able to convince GM to do the moral thing and let its owners and dealers know about the relatively simple repair to this issue (which, if you Google, you will find occurs in other GM cars besides Cadillacs), before a child loses a life by being hit by a car that can't brake in a neighborhood parking lot.

#93 of 105 ABS wiring harness short--Solution! by sirpontiac

Aug 24, 2012 (1:39 pm)

After reading mutiple posts on the "won't stop (ABS kicks in) when parking" especially when turning hard, like a normal parking lot! AND the obvious reluctance of Cadillac to acknowlege it as an issue, I thought I'd do my own work.
I replaced the wires from the wheel/speed sensor, splicing and soldering near the radiator. The parts for both sides were less that $100. with the right clip! I later tested both of the old wiring harnesses, 4 wires with an OHM meter. initially looked like a waste of time until I moved the wires around***simulating a hard right turn*** OHM meter pegged!
In my Non-Professional opinion problem is the OEM wire routing....causing repeated kinking of the wires on hard turns. I routed my new harnesses along the sway bay where this kinking is less likely.
DID I MENTION MY ABS PROBLEM IS GONE??
