Let me use one of the engineering and manufacturing problems as an example:
The AC.
There is a TSB to replace the AC unit because the Peugeot was too stupid to copy the design of every other auto manufacture that exists on the planet.
The fix is to remove the dashboard, which means remove the trim, to replace the entire AC unit.
Why? Ram didn't include a diverter valve on the heater hose inlet.
Seriously? Even my wife understand how stupid this is.
So, if you do a simple Ram Forum search, the easiest way for a 2019 Ram owner to improve the AC performance to install a shut off valve on the heater hose inlet. If you shut off hot water to the heater core, it'll improve the AC performance, which is why EVERY other manufacture on the planet has been doing this for 20+ years. Ram didn't. LOL.
So, they now have a TSB to replace the AC unit behind the dash.
Whoops.
Why didn't Ram just copy what every other Manufacture has done for decades by Including a diverter valve that shuts off hot water to the heater core when you want Max AC?
Because too many owners will accept it, and defend it.
Interesting Dodge/Ram hasn’t had a coolant diverter valve for a long time. They direct the air away from the heater core and to the A/C core, I personally see nothing wrong with that design. The coolant valves are trouble prone, so good reason to not use them. I was concerned about the Dodge/Ram wrapper around my first Dodge Ram, it was a better truck than my last two Fords, the current is still nice.
