I have been having an issue with the service stabilitrak message coming on along with the traction control light on my 2004 XLR. When this happens the brake lights go nuts and stay on while driving and go out when you push on the pedal. Also when this comes and you shut the car off and go to start it the press the brake pedal message comes on. Pressing the pedal and nothing the car will not start. When it does start it will not come out of park unless you press as hard as you can on the pedal.

My thoughts were this all has to be related. As it turns out it is. I was on Corvette Forum and the C6 owners are having the same problems as me

Here is the thread all 17 pages of it makes for some good reading http://forums.corvetteforum.com/c6-tech-performance/2336065-service-active-handling-consumer-action.html

On page 17 post 327 has the same problem as me. I also registered a complaint with nhtsa about my problem and if anybody is having problems please do the same. NHTSA has an engineer assigned to this problem.

I see that there is a recall on this issue, for Corvettes. Given the XLR is the same (is it not?), surely it should also apply?

Reading the extensive posting on the Vette site, it would seem that simply fitting the extra 'Terminal Position Assurance' (TPA) comb is not always sufficient. Given the recall states that 'fretting corrosion' (i.e. the connector is slightly loose and wears away) is considered to be the root cause, it seems to me that fitting the TPA is only going to work if the damage that has built up is minor. If it has worn further, then surely the connector block and/or the steering wheel sensor will also require replacement? The instructions posted at http://s680.photobucket.com/albums/vv162/NVL_AV8R/ , especially pictures 34 and 43 (step 12) show clearly what the fix is.

From the details of the recall, GM changed the production line twice, this is why the recall only applies to earlier years, but the experience of Corvette owners seems to be that even with the TPA in place the problem can continue. They have found that it is essential to ensure that the connector is properly seated (sometimes it isn't) and that the wiring loom is properly supported near to the sensor, with enough slack to allow free movement of the steering column.

Apparently the TSB that introduced the TPA is TSB-06-02-35-002B and the comb part number for the TSB is P/N 19179794 and it costs around $12, with the fix taking around 30 minutes to install.

Well I took mine apart again and reinstalled the comb clip again. I didn't have it in right the first time. I reinstalled it, applied a dap of electrical grease, and cut a wire tie holding the wire loom. So far it seems to have cured the problem.

How hard would have it been for GM to make the wire loom one or two inches longer at this connector? I do see that 07-09 Corvette owners and Corvette owners without the power column are having the same problem.

I'm not sure about the use of terminal grease. Silicon dielectric grease is (I thought) for keeping moisture out of connections, not a risk with this connection. On the Vette site there is a discussion about this, some say 'yes do', others say 'no don't'. I lean towards using contact cleaner for this sort of application, but not contact grease. I used to use the grease more, but have moved away from it, preferring to keep contacts as clean as possible and only use grease where there is a real risk of moisture. It is a good lubricant though, so has its place in connectors that need to be taken apart frequently.

2cs worth, if that?

without any messages on my dash my car brakes pulls right then left. i turn off the stabilatrack and the car rides normal. 5 times within 10 miles

has anyone had this problem and any suggestions whats causing this?

I also registered a complaint with nhtsa about my problem and if anybody is having problems please do the same. NHTSA has an engineer assigned to this problem.

My 2004 is also occasionally registering a problem with the stabilitrak. How do I register a complaint? Do you have a file number?

Thank you

I strongly recommend that you take your car to the dealer ASAP. This is a safety issue that should be corrected before you drive your XLR again.

As I am sure you are aware your life as well as any passenger and other drivers and pedestrians are at risk.

I mentioned this to my dealer and while they were doing a big job for me, they added the TPA connector at the same time. They even had it in stock.

I'm having the same problem but when I called my dealer he was asking me for a service bulletin. i saw this one but why is it that it's not here on Cadillac TSB (http://www.automd.com/tsb/cadillac_m/). Do you know other official list of tsbs? thanks for any help. I really need it.
