Looks like they cant get anything right these days. Youd think they just started building automobiles.

It’s not just trucks, I’m seeing a lot of bad designs from the new breed of engineers. I think @securityguy needs to educate these newbies.

Welp, just checked my build sheet looks like it's a winner. Time to build a obs with 400 small block 202 heads 750 holly with 700r trans. I'm about done with Gm. Third truck in a row that has had some sort of issue.

I don't seee it changing with Barra in charge. She was a DEI placement that got the job with the help of the libs to fully embrace the green new scam and replace ICE vehicles. By making them less reliable/desireable, in part, she could slowly kill them off. She went all in and dumped heaps of cash into EVs nobody asked for at any time in GMs history. Nobody driving a Chevy ever gave a shit about an EV that costs $100k+, but your funding them anyway. They wanted a $23k Bolt and she killed that too. Now they are getting killed in ChiNa and they can't sell them here......total fucking loss just like Solyndra and Ivanpah Solar.

Yep Agreed! Don't forget she also killed the Camero. EV's aren't a eco friendly solution like people think they get there power supply from somewhere

Let’s not forget the workers assembling these things which are highly paid so there should be no excuse.
