Chevrolet HHR spongy pedal problems

Filed Nov 13, 2017 · Brakes · 40,000 miles · MI

After sitting overnight the vehicle has a hard pedal and would not stop. It appeared to be from the booster not holding the vacuum. There was a buliten #09-05-22-001a that addresses this issue but it requires an additional vacuum pump to be added to the vehicle that was not in the original design. I feel this should be covered by gm and not the customer since it requires a new additional part to address the issue and was not due to normal wear and tear on the vehicle.

After backing out of a parking space, stopping, and proceeding forward I attempted to again apply the brake after about 150 feet of moving forward. The brake pedal was hard but the brakes were not being applied at all. It made no difference even when applying much additional pressure to the pedal. It felt like the ABS was preventing the brakes from working as I coasted to a stop. After a brief amount of time the brakes seemed to work normally. It has now happened two additional times after the car has been sitting for a number of hours.

After purchase of a new 2009 ss hhr. During the morning I backed into my garage and noticed a very soft brake pedal. I then started to proceed into the garage and when attempting to stop the vehicles brakes would not comply with my brake pressure and the vehicle proceeded to hit the side of our house. This became a routine situation upon "cold startups" and when reported to the dealer,(classic chevy chevrolet, grapevine, tx) after several poor stops, my service advisor advised "yeah we know about it". But there was no fix at the time when confronted with a possible fix he advised that " I made arrangements to have the car repaired when the fix from gm engineering was issued refused to service the car. Gm customer service personnel and the bulletin advised that "they are working on the issue." I never got the rear of the car repaired due to the failure pressure failure.

After purchase of a new 2008 hhr on 22 september 2008, I drove the vehicle home and upon getting into it the next morning I backed out of my garage and notice a very soft brake pedal. I then started down the drive way and when attempting to stop at the street the vehicle's brakes would not comply with my brake pressure and the vehicle proceeded into the street. This became a routine situation upon "cold startup's" and when reported to the dealer,(john donoghue chevrolet, whiteville, nc) after several poor stops, my salesman advised "yeah we know about it as we've had the same problem on 2008 solstices". When confronted with a possible fix he advised that " a part on the turbo fixes the problem." I made arrangements to have the car serviced upon my return from vacation on or about 26 oct 08. I dropped the car off with the service writer/manager and no mention was made as to poten tial problems fixing the car. Upon my return several hours later I was advised by the service manager that the problem is systemic to 2008 turbo engines and general motors doesn't want to recall the cars. The dealership service manager provided me with a service bulletin that gm put out as a potential "fix" but he refused to service the car. I took the vehicle to another chevrolet dealership and they readjusted the computer, per the bulletin; however, the vehicle still does not stop properly on cold startup. Gm customer service personnel and the bulletin advised that "they are working on the issue."

I am having a problem with the brakes on my new 2008 chevrolet hhr/ss. When first applying brakes after initial start-up and after sitting long enough for vacuum to leak down. There is an increased effort to apply and travel of pedal is also increased. Pedal is spongy and booster is inoperative until vacuum is restored by revving engine or driving a short distance. This vehicle is equipped with a turbo and vacuum/boost gauge. The initial vacuum is dropped when applying brake. It has been in for this problem twice, left overnight both times, and duplicated both times. The dealer reprogrammed computer per service letter. The second time they supposedly ordered a mastercylinder but still no parts have been changed, probably not even examined! Now they tell me this is normal operation and I tell them it's not! The dealer service mgr. Has told me that gm knows about this but have no repair available. He blames it on the turbo! It is surely a vacuum leak or booster problem yet they seem unable to understand! I have been a mechanic for 30+ years and I know this is dangerous and needs to be repaired before someone gets hurt! The dealer doesn't even want me to bring it back in as they say "it cannot be fixed, it is a design problem!"
