We bought this car with 40,000. It has 63,000 on it now and the compression rod is bad. How could regular scheduled maintenance prevented this?
What scheduled maintenance would have detected a bad lower compression rod? on 2007 Cadillac CTS

you could not predicted a rod going out.
I think you may be referring to is a connecting rod? Is the engine making a knocking noise? My guess you may be dealing with a connectiong rod bearing failure. Oil change maintenance intervals can be a key factor if not done regularly. Other things could cause that bearing to fail also.
The oil changes were done regularly. From what we can figure out the only other scheduled maintenance due while we owned it is spark plug changes at 55,000 miles.
If you have not owned the car since it was new....maintenance that may have been done or not done by previous owner could have been cause of the bearing failure.
