No buy backs for all as I was suprised they did the one. They may be wanting it back to use it to see what the problem is since it is already failing.

At this point it looks as if GM has not figured this out yet if they have they would bew fixing the rest. An 09 in not a sure thing of not having the same problem.

GM will figure this out soon and when they do we all will get a Recall for a TSB to fix this problem.

I just hope they figure this out before someone get hurt.

No matter how well a car runs it is useless if you can't stop.

 

I filed a Complaint today with the NHTSA and I feel everyone here with the problem should do the same thing!

 

I understood 88ls1blazers' comment....


Frankly, I thought the same thing. Think about it....is it SMART to knowingly drive a vehicle with faulty brakes. This statement kind of said it all.....

I don't know whether to bother to even take it in again. Nothing will be done to resolve the problem


However, to respond to the brake issue on the SS's.....

I think owners should start filing written complaints with NHTSA, as suggested above. It COULD force GM into a recall.

 

My experience is the same as OCMerrill.
Maybe few of us remember driving a vehicle without power assisted brakes.
I used to drive a '65 Mustang with front disk brakes. You had to push pretty hard to get that car to stop.

The concern could be the inconsistency we are experiencing because the HHR SS is supposed to have power assisted brakes all the time.

 

I agree the car stops but it takes pedal effort with the booster not evacuated (I feel this is the problem and have spent a few years as a wrench).

Pedal to the floor is an EMERGENCY repair situation. Every time we have had a hard pedal the car will stop fine but with mega extra effort. GM needs to react to this, You know they are reading.


Hey GM...head out of sand please....

 

My SS had this brake problem every morning. After about 10 hours sitting the brakes were gone. I had mech brakes on a 67 olds - those stopped better. After 4500 miles I had enought last week I took it to the dealer with the TSB, they reprogrammed the car. So far the car is 100% better. The pressure required to stop the car is normal but you still can feel some pulsing like anti-locking is active. But you can easily stop the car. If you are having this trouble I would definately have the work done.

 

You can be assured GM is not just expecting this to go away. They know the impending Goverment recall that could come forth and they know the legal action that could be brought.

Now finding the problem is step one. They then come up with a way to retro fit a fix. Test the fix to make sure it will work Then they have to make the parts to do the job.

This takes some time and we are looking at 6 months or more. The TSB fix for my GP took 8 months.

I am not sure of the lead time here but I am sure GM has been looking into this for at the very least a month or two.

Now what we have is a low vaccume problem but we have not lost the brakes. Los of vaccume as pointed out just takes more effort to push the pedal. Now if the pedal is hitting the floor you have a hydralic problem with low fluid, air in the line or a bad caliper or master cylinder. All very uncommon on a new vehicle and they don't fix themselves in a few min of idle.

For right now it is best to contact youyr dealer if you have this preoblem so your on record and use caution at start up. Also it would be good to contact Chevy directly and let them know too as the added pressure may or may not help but again your on record.

Keep track of the dates and time you make contact. documentation may not be needed later but if needed you will have it.

I would ask Chevy to keep you updated on what they are doing, the squeeky wheel gets attention.

Above all take this to the dealer and get it documented!

Lets try to keep this tread on target of getting a fix on the brake problem. I do not have it yet myself but I may be a future problem so I have a vested interest here as does everyone else.

Harsh words or not he does need to keep on the dealer. You give up on it they will forget about you.

 

I am so glad I read this. This morning I could barely stop at the stop sign by my house. I have about 5400 miles on the car and it scared the crap out of me. What do I tell the dealer when I bring it in?

On another note I have read people with issues with the suspension. Maybe it is related to the brake issue but my front end feels a bit wobbly. I noticed it this morning as well when making a low speed turn. Something felt "not right" I checked my tire pressure and they are all pretty much even and the PSI fluctuates between 33 and 36 as the tires heat up. On real hot days it gets as high as 38 but they are all even and with in 1 psi of each other. I want to bring it in for service but I do not want the dealer to think I am nuts or try to blame it on me. When I had my S10 SS I felt something was not right and at first they said nothing was wrong. I insisted they put it on the rack and they said the U-Joints were bad and immediately accused me of taking the truck off road. They even tried to trap me by saying "Have you ever driven over railroad tracks?" After I was insulted I went to the Dealership Manager (which thankfully is a friend of my fathers) and he went back and gave them an earful and said fix the damn truck. I guess I want to go in there with some information to avoid them trying to screw me. I am a computer guy but I am not "car stupid". I know how one is supposed to feel when it is normal and I know my parts and what they do (for the most part) but some of the details on what to look for do not come that quickly for me.

 

Just go in and explain to them your having a loss of power assit for the brakes under start up and first driving it after sitting over night. Loss of vaccume?

You can even refer them to this web site and the several threads on this topic.

It is common for dealers to be in the dark on this, On the TSB on my GP I learned everyting from the GP web site and the guy GM was working with to fix the problem.

He gave us the TSB number and the part number for the repair part. I had to tell the dealer and give them the info. THey checked it and ordered the parts it was fixed a as soon as the parts came in.

Don't expect it to be solved the first time in unless GM has a fix by the time you take it.

As I have stated get it in and on record. The more that are reported the fast GM will want to solve this.

Keep in mind not all SS are having the problem and only 4519 were built. So the more that are reported the better.

 

Thank You. I will call them tomorrow or make an appointment online. Maybe they will give me that Trailblazer SS again for a loaner like they did last time it was in when they broke my heater controls installing the PAL hookup. They were out of Malibu's that they usually give for loaners and I guess some idiot double booked the loaner they said they had for me. So they gave me a dealer Trailblazer SS because my Father knows the dealership owner/manager and jokingly told me that he knew I wouldn't settle for anything less than an SS since my last 2 cars before the HHR were both SS's.

What do you think I should do about the wobbly feeling that felt in the front? I read in another forum to check the shocks/struts for leakage. That could have been all in my head though but today it did not feel as tight as it was normally when driving.
