Great update, thanks @rescueswimmer.Just wanted to drop a quick note on how the car has been and what we have had to do deal with over the last 2 years or so.
The car has been pretty much 100% reliable with a few hiccups along the way. I'll list them in a minute. The only thing that I have noticed, is that documented MPG has gone down 2-3 MPG over the last year and not sure for the reason, It actually had better MPG when it had 0 miles on it than it does with a 100k Maybe all the Regen update flashes are killing it?
1 Set of tires
1 Steering gear box
2 fan blower motors
1 transmission seal gasket (leaking)
1 DEF tank heater
2 NOX sensors
2 or 3 fuel filters.
10 Oil Changes
1 Timing belt. I just did the timing belt job this weekend. It really is super easy and if you have the tools and mechanical knowledge I think most DIY'ers could do this them selves. Just be careful when re routing the timing belt and torque everything to spec and you should be fine.
Future projects starting this month. Replacing S&S with Billsteins. Brakes are still pretty good but wife says it does not stop like it used to so going to do a brake job as well. I had purchased the Gm extra guard to 100,000 miles so now that we are out of warranty I'm doing the delete kit as well.
Other than that I can't think of anything that would be a deal breaker for us and the car. YMMV
One thing, you didn't mention the infamous Turd Handler...ROFL
