I have a 07 Solstice - automatic. Since I have had my car for 9 years, I do regular preventive maintenance & I let it warm up in the morning before I drive it.
In the last 2 weeks, when I apply the brakes, it jerks & it sounds as if the motor is about to fall out - this does not happen all the time, so far, it has happened on 3 separate occasions.
I took it to the shop & was told they hooked it up to the “big expensive machine” & there were no codes, nothing wrong so they had the alignment guys look at it & said that when I had the rotors & brake pads replaced last month, they were not burnished so they burnished them.
2 days later, it happened again, I drove it to the shop & my Service Advisor test drove it w/me for about 20 minutes & of course, the car did not jerk. He told me to keep track of what I did right before it started to jerk.
A week later, it did it again so I pulled over, turned the engine off, sat there for about 5 minutes, turned the engine on & it was fine, no jerking, no noise, ran perfect.
The 1st time it jerked, I simply pulled out of my garage & the other 2 times was right after I filled it up w/gasoline - so far it has only done this in the morning.
Any clue as to why this is happening & how to fix it? My Service Advisor is at a loss - please help!
