Piston Slap: Mazda's Rust and Tire Size Trust Gap?

Curb Appeal? (photo courtesy: Greg)

Hello Sajeev, David Holzman says I should write to you about my Mazda concerns.

1. Concern #1. In two out of three dealers there was significant rust at the center of the wheels due to the wheel caps not having been put on. I only took three pictures, but essentially: at New Country Mazda in Saratoga Springs NY 100% of the Mazdas had no wheelcaps on in the lot and were all showing various degrees of rust. That includes the one in the showroom, you can see it in the pic with the tile floor.

Howdy Sajeev,

I have an unique issue with my 2010 Ford Fusion Hybrid. I’ve posted about it at fordfusionforum.com, and no one so far has heard of anyone with the same issue. Here’s the link for the post, and the text is reproduced (and edited to remove site-specific context) below:

Piston Slap: The Wheel That Won't Budge

Hey Sajeev. Looking for your wisdom, or perhaps that of the B&B. I’ve got a 2005 Hyundai Elantra with about 50k miles. Back around 40k, we had new tires put on it at Sears. Now I want to rotate the tires (yes, I know, I should have done this a while ago), but when I got to the very last wheel, I ran into a roadblock. The rear right wheel is fused to the hub! It seems to be rusted on. Poking around a few forums online, I got a couple of ideas:

  • MaintenanceCosts Nobody here seems to acknowledge that there are multiple use cases for cars.Some people spend all their time driving all over the country and need every mile and minute of time savings. ICE cars are better for them right now.Some people only drive locally and fly when they travel. For them, there's probably a range number that works, and they don't really need more. For the uses for which we use our EV, that would be around 150 miles. The other thing about a low range requirement is it can make 120V charging viable. If you don't drive more than an average of about 40 miles/day, you can probably get enough electrons through a wall outlet. We spent over two years charging our Bolt only through 120V, while our house was getting rebuilt, and never had an issue.Those are extremes. There are all sorts of use cases in between, which probably represent the majority of drivers. For some users, what's needed is more range. But I think for most users, what's needed is better charging. Retrofit apartment garages like Tim's with 240V outlets at every spot. Install more L3 chargers in supermarket parking lots and alongside gas stations. Make chargers that work like Tesla Superchargers as ubiquitous as gas stations, and EV charging will not be an issue for most users.
  • MaintenanceCosts I don't have an opinion on whether any one plant unionizing is the right answer, but the employees sure need to have the right to organize. Unions or the credible threat of unionization are the only thing, history has proven, that can keep employers honest. Without it, we've seen over and over, the employers have complete power over the workers and feel free to exploit the workers however they see fit. (And don't tell me "oh, the workers can just leave" - in an oligopolistic industry, working conditions quickly converge, and there's not another employer right around the corner.)

  • BrandX "I can charge using the 240V outlets, sure, but it’s slow."No it's not. That's what all home chargers use - 240V.
