Rust Protection- Dealership Options

[Hutch33]

I'm buying out the lease on my 2021 Lexus rx450h Sport, and the dealer is asking if I want to get the car rust proofed when I come in for the transfer.

Are the dealer options worth it? Are there better options? 

Dealer- 1. Undercoat/ soundshield. $649 +HST 2. Rust inhibitor Spray $649 +. 3. Corrosion Control Module $1299 +

Also is there a manufacturers rust warranty without Lexus extra rustproofing?

 

Thanks for your help!

Cheers

The 2021 Lexus RX 450h Sport comes with the following warranty coverage:

• Basic Warranty: 48 months or 50,000 miles, whichever occurs first.
• Corrosion Perforation Warranty: 72 months with unlimited distance.
• Hybrid/Electric System Component Warranty: 96 months or 100,000 miles, whichever occurs first.
• Maintenance Warranty: 12 months or 10,000 miles, whichever occurs first².
• Powertrain Warranty: 72 months or 70,000 miles, whichever occurs first².
• Roadside Assistance Coverage: 48 months with unlimited distance².

So, if you encounter any issues related to rust perforation within the first 72 months, Lexus has you covered!

And that summary is the basic coverage?

Do you recommend getting rust protection at 36,000 miles?

I would never undercoat a 3 year old car and to be honest, I would never undercoat a new car in high salt areas. All that does is trap anything that is already there and anything that gets in behind the undercoating. I would get it well cleaned underneath then have it Crown or RustCheck oil protected. We see a lot of salt up here just like you do in Ontario, those two are consistently the best at slowing down corrosion.
