i am an accountant not a car mechanic and had started having issues last year with dynamic drive in my car, somewhere in Nov 2011. In July 2012 i had rear wheels replaced as one tire war not repairable to had two rears replaced. then i saw the dynamic drive issue again. didnt pay attention, since the error came after 10 months. however, after this error report, it became kind of more frequent. so took it into the garage. three days later the battery was replaced. remember the car was 5 years old but only 50K miles. This did not fix the problem. took it back in there. the mechanic says he did a rodeo test. kept the car for a month. when drove off the shop, heard a sound, as if something moves in the truck from and hits the inside. went and checked but the trunk was emply. three to four days later hear it again but this time the intensity was low. now there is a constant sound. some one says that may be there is a loose part that is touching the wheel. etc..
my concern is, is the mechanic gona say it is not related to the repair doen earlier? I am not able to comprehend what repairs lo sensors he did to fix the dynamic drive issue.
any thoughts and suggestion how to resolve. ended up speding 2000 to fix the problem. not happy with this milage on the car.
