'08 Brakes - Non Recall Notice

Don't know if anyone else has received a letter from GM yet, but I got one today regarding the problem of no brakes when first starting our GXP's. It's not a recall, but an offer to "calibarate" the brakes with something "improved." It's an option that you have to call your dealer and ask for - referring to TSB0-7-05-25-007B. Can someone pull up the TSB and see what it actually says? On the same note, I wonder what ...007A says.

Was another site member, krisis7, that posted it (and you borrowed for another thread) shortly after it came out back in May.
https://www.solsticeforum.com/forum/f...nes-gxp-45631/

The original version had the calibration release only for Automatics, the "A" version changed some wording and the "B" version added the manual transmission calibration release.

Here is a cleaner copy of the TSB and a PDF of the June 26th target mail date letter (generic sample):
Quote:
#07-05-25-007B: Pedal Noise/Buzz, Extra Effort Needed to Depress Brake Pedal After Vehicle Has Not Been Driven For Extended Period of Time (Reprogram ECM and ECM) - (May 16, 2008)

Models: 2008 Pontiac Solstice GXP
2008 Saturn SKY Redline
2008 Daewoo G2X
Built Prior to the Breakpoints Listed Below


--------------------------------------------------------------------------------
This bulletin is being revised to announce that the calibrations are available for vehicles equipped with manual transmissions. Please discard Corporate Bulletin Number 07-05-25-007A (Section 05 -- Brakes).
--------------------------------------------------------------------------------
Model-VIN Breakpoint

Saturn-8Y129355

Pontiac-8Y129363

Daewoo-All Vehicles


Please make a copy of this bulletin and give it to your customer for future reference.

System Description
The 2008 Pontiac Solstice GXP, Saturn SKY Redline, and Daewoo G2X are performance vehicles that come equipped with the 2.0L (RPO LNF) engine and an advanced performance braking system called Optimized Hydraulic Boost (OHB). The OHB brake system utilizes the Anti-Lock Brake System (ABS) to assist vehicle braking in low brake vacuum conditions.

The brake systems on these vehicles use engine vacuum to assist the power brake system during most brake applications. The OHB system supplements the power assist brake system when there is low engine vacuum, such as when the engine is initially started after an extended period of no operation or while operating in high altitude.

Condition
Some customers may comment on one or more of the following brake system characteristics:

• Increased brake pedal effort due to low brake booster vacuum conditions that may occur after the vehicle has not been operated for an extended period of time and/or at higher altitudes and restarted.

• Brake pedal movement or pulsation accompanied by a ratchet sound coming from the brake system during OHB activation when braking.

Correction
Reprogram the ECM with an updated engine calibration. This new service calibration will increase engine vacuum when the vehicle is initially started.

Reprogram the EBCM with an updated brake calibration. This programming event will return the module to its original state if it was previously updated for this condition.

These calibrations will be available as an EBCM/ECM programming sequence event. From the controller list, select "EBCM/ECM Sequential Program."

Important:

• After the EBCM/ECM calibration, brake pedal movement or pulsation accompanied by a ratchet sound will be reduced.

• Allowing the engine to idle for a period of time after the engine is started will help increase the vacuum for the power assist brake system.

• If the SVC BRAKE SYSTEM message is displayed on the DIC. The brake system must be inspected for any faults in the system.


Refer to the Owner Manual (page 4-4 for the Pontiac Solstice or Saturn SKY) for additional information on this brake system operation.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

The recalibration is covered under the New Vehicle Limited Warranty for 36 months or 36,000 miles, which ever comes first.





The NHTSA has closed their Preliminary Investigation into the 2008 Solstice GXP and 2008 Saturn Sky Redline and the OHB System. So it appears no further investigation or no escalation to a recall request will be forthcoming.

So has anyone had this done?
Would you recommend this - I drive my car almost daily, never had this issue. I really don't like the idea of an increased idle to fix a vaccume issue, sounds like one evil for another?
What is the felling aout getting this done on my car? would you do it to yours?

Thanks

I just had my brakes looked at as well when I was having another minor thing replaced. They are not working well in reverse. They did the recalibration and I truly do not feel hardly any difference. The brakes in reverse still randomly choose when and when not to work. It makes me VERY nervous to back up, esp. if on an incline.

I have a steep driveway and backing out is interesting when the engine is cold. (Really bad design.)

I went to the local dealer today for the update. They read the update from GM and had no idea what to do. Waste of time! I think that I will just keep living with it.

I would find a new dealer. The procedure is straight forward and GM offers phone support to the techs as well.

I had mine done Saturday; it's a small country dealership and they knew exactly what to do when I showed them the letter. I have not noticed any change in behavior on my GXP.

I got the service bullitin taken care of on 8/1/09 - The delearship needed the car on a week day so they had the phone support. All is well - I fell no change in the Solstice. Mileage does not seem to be any different in the last couple of days.
CHEERS & THANKS ALL FOR THE ADVICE

is there any way to find out if my solstice has already had this done or not. i talked to my srv manager yesterday and he said it doesnt need it. I bought the car new, but it sat on the lot for 10 months, and am wondering if it was already taken care of while it sat there.

Real easy, when your car is cold, and I mean cold sitting all night cold, start pumping the brakes once you start it.

You will feel the "pedal" grinding and so on, you cannot miss it. If you don't feel it you're OK.

Oh and you will not be able to stop your car if you start driving right away on a cold start.
