2008 Chevy Uplander
 

The P0449 is starting as well as a few random codes. one for a solenoid at the throttle body, that comes and goes. Read for more on why I am not sure if I should run now or fix this

This is the first GM I have owned in a long time and may be the last, I purchased it with 89,000 miles all seemed well. after 117,00 everything started to fail, First the left front bearing that controls ABS, and a host of others failed. The Onstar failed at about 101,000

I am trying to see if this is just a bad vehicle to own for a work van, or if this is rare and does not happen often.
