Iput 297 thousand miles om a 2003 Pontiac Grand Am between Sept 2002 and June 2010. In that time I put a left front hub and rotor, and an alternator on it. Also had about 3 sets of front brakes on it. That @($^%$^ traction control uses brakes. After I unhooked it, brake wear went away.
I recently gave it to my son-in-law who is putting 500 miles a week on it. I told him to get the rear brakes ckecked and the mechanic said it still had 90% shoes on it. After 300,000 miles!! It also uses a half Ouartof oil between changes. That blamed American car (pre-OBOZO of course) just ain’t no good, I guess.
After sitting for a year and a half, he had to put a new alternator on it.
Apparently, the problem with rear A/Cs is legit. (I didn’t even know they had separate rear A/Cs!) They weren’t designed with the expectation that solitary drivers would constantly turn the rear A/C on but much lower than your front A/C.
