To add insult to injury, they are fully capable of adding the 4g module because Canadian Volts were able to be upgraded. GM decided to not let US owners pay for the upgrade, because fuck us that’s why.

Not the OP, but you can clean all the parts when torn down for service. Vacuum bags instead of holding tanks also helps with that, but mostly it’s the filters. Replace all the filters and the smells go with it.

My mid 2000’s Japanese SUV. Manual transmission, regular old v6 gas engine, only one “computer”. Same engine, drivetrain, and frame for 3-4 different models so parts are abundant. Can repair/replace anything on it with a handful of power tools and elbow grease.

That’s how the turtle do.

Seriously, some aquatic turtles can extend their time under water by using their cloaca like primitive gills. Look up cloacal respiration.
