Unfortunately this has been done 100s if not 1000s of times since 2005. GM has recently admitted there is a problem but makes light of it by saying, "It can cause an accident if the driver does not compensate." COMPENSATE!!! ****! Drive 135 mph have the front brake lock up and tell me how easy it is to compensate!

They are however doing "extensive testing" and have replicated the problem numerous times. So at least they admit the problem now.

 

1) Where do you disconnect the WPS?

2) What will I lose if I disconnect it (just AH and TC)?

 

Another 05 here with the AH problem in the parking lot. Quite embarassing when your just trying to park and have to make a 5 point turn to get into a parking space a F150 could get into in one try. Or turn the car off and on so you can unlock the right front brake.

I can't imagine it locking up at speed.

^^^^+1

I can pull the ABS fuse but I'd like to have ABS.

 

Are you serious. That's about the dumbest thing I've heard. They might as well just say, It can cause an accident but you have to be ready for it everytime you drive...

Sometimes I wonder if GM has their head up their a$$. I don't know why they just don't make this issue a "recall". They're only opening their doors to lawsuits. I wouldn't be suprised if it hasn't already happened.

 

On top of it, I can see GM saying "well your ECM was reprogrammed so it's not our fault" and using that as an excuse for those that might have some mods........

Anything they can to not have to accept responsibility.......

 

Oh I wouldn't doubt it but then again this has happened to some owners with bone stock cars. I would like to see them try and wiggle their way out of that one.

 

Just for good measure I went by Criswell Chevy where I used to work and asked some questions. Marcus the performance team leader assured me there is no fix for this issue as of yet. They have been replacing the WPS in the cars that the comb fix doesnt work on.

So basically there are thousands of people out there on the road sitting on ticking time bombs with no sure fix other then to disconect the WPS.

 

Does this affect the 2008+ cars???

 

I can't say so as a fact, but if GM doesn't know how to correct the problem on cars they built before 2008, then how would they know what redesign is required so that the 2008+ cars don't have the problem. I was driving at 162 MPH on Talladega this past Saturday with my 09 Z06. If one of my front wheels had locked up, I wouldn't be on the forum tonight. I would be resting peaceably in my casket, but hoping that someone will sue the hell out of GM on my behalf.

 

If it isn't happening on post '08's... Then they must of changed something but don 't want to retro the older ones?
Is this solely a complete lock up of a wheel...or have ppl experienced some type of braking where it feels like the front-end is pulling to the left?

 

I have 2007 I had the service AH message and I took it in IIRC. I never seen it again, this car has be a love hate relationship, but rest assure it's gone if that ever happens to me.

 

GM bought back my 2008 because of this issue (plus many more electronic problems with the car). Almost shot me into a doctor's office and the ditch. When I then jammed the brakes to keep from going sideways, all 4 wheels would stay locked until you shut off the power, then they could load it on a flatbed to the dealer.

Mine locked up twice, luckily both times while going about 40 with no one directly behind me.

They changed virtually every module/computer in the car, most things twice. All that was left was to rewire the car.

I told them they were not rewiring it, and to prevent a lemon law claim GM bought it back.

I was firm but professional. GM did make the best of a bad situation for me.

 

I have a 2005 C6 and mine has locked and only on sharp turns. Once while exiting a parking space. I turned the car off and back on and it drove like nothing happened. all this happened after being taken in for the AHS recall!

 

It's definitely BS that I had to disconnect the WPS rendering the system inoperable which is a big part of the technology we pay for. However unless someone can come up with a fix they can bet their life on then I will not be putting my life on the line.

 

If I keep 30 lbs of pressure in my tires and disable tc and ah, this won't happen I take it? It's only when you drop below 24 lbs?

 

I had this happen twice on my car. It said, "ACTIVE HANDLING ACTIVATED." I was traveling 25mph in town and the right front went into impending lockup. If the curb wasn't there, I would have taken out a whole family of pedestrians (and their dog.)
Drove immediately (3 miles) slowly to the dealership, where they put the clip in it.

Later, I went to the track for a lap...

This was on a 100% stock, as delivered car.

Hasn't happened for a coupla years now.

 

Active handling almost killed me too. (18-wheeler on the left side, guard rail on the right.)

 

Man sorry to hear that..that sounds like a BAD situation, glad it worked out in the end.I just don't get why the brakes are locking, so the AH activates by itself , why then does another system (ABS) lock..I thought the whole point in ABS is so brakes won't lock.mine has never locked but does display the "service active handling"..AND now the cruise control comes on, on it's own.I can handle little quarks ..but if the brakes start locking I'm out.

 

Issue is not limited to 2008 or earlier. Mine is a 2009 LT1 - bone stock, factory wheels and tires in good condition at proper pressure.

Shortly after 15,000 miles the Active Handling started kicking in below the speed limit in turns on dry roads I'd driven previously with zero issues. No brake lock up, but Active Handling simply let off the throttle, which caused the car to unload the suspension and want to drift into oncoming traffic.

Dealer said there was a code, I don't know which one, and replaced the steering gear. The car still misbehaved after this, but differently. On my test drive it let off throttle and applied brakes to slow down the car when not necessary. In this instance, I was lucky there was no one behind me or I probably would have been rear ended. Two days later the DIC showed the message ABS Active while coming to a gentle stop from 30 mph on a dry street but it was not active because the brake pedal was not pulsing and there was no typical ABS noise.

Brought it back and, surprise, the dealer's Tech 2 reader shows no codes and a snapshot of the info with the dealer service manager in the car while AH misbehaved was sent to GM. So a GM person who I am not allowed to speak with looks at the info, ignores the fact that the car is now behaving differently than it did in the first 15,000 plus miles, and says there is nothing wrong.

The dealer service manager said it was easy to replace the SWPS and they would do it, but after I leave the car with them they tell me they had to order the steering gear again because the SWPS is part of it. This is confusing, which is it? Isn't the sensor on the column in the cabin??? So they've had my car for almost two out of the past three weeks (expect it to be ready today) and I don't have much confidence in the fix because this seems to be an absolute guess on their part. If it's not a guess, then they haven't explained it.

 

Wow, this is the first I've heard about this...
