'18 Chevy Silverado - Engine Light On - EVAP Leak & Problem With Fuel Pressure Sensor

In this video I bring you along as I have a look at a customers 2018 Silverado that got dropped off with a customer complaint of a service engine soon light on. A quick scan showed an issue with the fuel pressure sensor as well as an EVAP leak. Doesn't take long to see that the salt is doing wonders on the rusty ol' Chevy.

Its a hard deal for the car makers. I completely understand actually wanting plastic parts in that environment as steel dosent cut it. But here in australia ,with a dry ,hot, enviromnment a steel component will way outlast anything made of plastic. Usually our cars have very little rust but the interiors and any plastic engine bay fittings turn to dust.

I live in Arizona, U.S., and I'm still driving around in a rust free 1972 Ford Pinto wagon. But we have the same problem here with sun. It burns the paint off, and rots the interior and tires.

[@mattbrown5511]

The U.S. has so many different environments that is almost impossible to design one vehicle to withstand all of them. Also, not all of our states use salt and/or sand on the roads in the winter. When I lived in Arizona, I drove a 1974 Datsun 510 around that was rust free. Getting parts was an import nightmare, but it was a fun little car. But in Indiana, where I grew up, cars rarely lasted more than 15 years with the best of care.

I've spent roughly 1100 on repairs, not maintenence, in the last 10 years of ownership. I can't say VW is stellar for reliability either. I think every brand makes a few gems now and then.
