2016 Lexus RX 350. Under carriage really really badly rusted. Rust broke lock on passenger door. Dealership will not even investigate what can I do ---

You need a body shop to look at this thing to determine if it safe to use . You are probably out of the warranty period so the dealer will not fix it for free . Actually they did right thing by not taking it in because this is not something dealers normally do. Is there a chance that this is a flood vehicle that you bought used ? ---

The car isn’t four years old. Park in garage. 9000 miles. Dealer pretty much just said we can’t help you. ---

The corrosion perforation warranty on a new Lexus is 72mo. unlimited mileage. Dunno if that’s transferrable but there should be a number in your Owner’s Manual for Lexus corporate. ---

Perforation vs surface rust will probably come up as the issue. ---

> [@KayCullum](#): > > Rust broke lock on passenger door. The passenger door doesn’t have a lock cylinder. There is a lock actuator, common failure that has nothing to do with rust. There is a door latch, plated steel and plastic, shouldn’t rust. The suspension parts do not have durable paint like the car body, surface rust is normal. ---

How is a car titled as a 2016 not, at the minimum, four years old? It was likely assembled sometime between August 2015 and July 2016, but I don’t know when Lexus switches over their assembly line. Yet, only 9,000 miles on it!
