Bought my 2024 Prime last month. At final paper signing salesman tried to sell me an "Auto Saver Electronic Rust Protection System" that plugs in to the OBD II port. Started at $900+, then as a "final" offer dropped it to $495. Said I would research it and get back to him. Found same one on EBay for $235.
Did some research and most seem to think Cathodic protection rust protection works on submerged metal like boats or pipelines. Could NOT find any qualified authority (Car & Driver, CNet, Consumer Reports, Road & Track, etc) who has done any research on the topic.
I'm a born-in-the-wool skeptic, and this seems like the perfect P.T.Barnum snake oil. Anyone found any rigorous or scientific analysis on the device/method of rust protection other than anecdotal stories? I'd love to be proven wrong and have a relatively inexpensive, easy to install method of rust protection, but if it is so great why isn't Toyota (and other manufacturers) using the technology as OEM?
