I recently bought a 2020 CRV Hybrid. Even when it was new I noticed that the finish on the rear brake disks was kind of rough. I have about 2500 miles on the car now and the front brake disks look really bad too, heavily pitted and rusting. Has anyone else had this problem? It looks like they were made from defective steel.
Overall I like the car with my main gripe being poor gas mileage. I'm getting between 32-34 MPG, much less than advertised.

All I can tell you is I have the same mileage (2500) on mine and all four disks look good, no sign of rust or pitting at all. They look brand new, which they practically are.
I live in a very dry climate, rusty brake disks on any car are unusual here, if they are driven at all.
I'm getting the same lower mileage as you. I attribute it to cold temperatures and my desire to be warm, winter blend fuel and snowy roads.
I was getting over 40 mpg last August and September, so I expect it will improve when it warms up.

Thanks for the feedback. I think that I may need to give the dealership a call on this issue. I live fairly close to the ocean so humidity is an issue, but I have only had the car since early December so this level of wear on a new car seems out of line. The brakes work fine, so there is no functional issue, but its weird having the brake disks on a new car look so worn so fast.

Discs can have that look after several hours if they were subject to splashing of water or some other liquid. It's not uncommon. If the brakes are working as expected, then keep and eye on things but drive as normal. If they are not working as expected, take it in asap.

I'd certainly let the dealer have a look if you have any doubts.
The ocean would indeed make a difference, as would road salt if they use it in your area.

Remember you aren't really using the calipers and rotors unless you are stopping hard (more than 1/3G I read somewhere) or slowing below effective regen speed, so the rotors don't get "cleaned" by use the way a friction-only braking vehicle's would.
If you are making heavy use of the regen paddles the rotors would also not get cleaned as much, since they can't activate the calipers.
What you are seeing may be perfectly normal for your area. Around here 15% humidity is a damp day.
(Oh, welcome. If you update your avatar folks will be able to see where you are if they hover over the flag (if you want them to that is)
One last thought: take a look at the rotors on other cars in your area, see if they look similar.

Rotors are cast iron. They WILL rust just from water.

I washed our V today, the rotors had a coating of rust within an hour. So I drove it around the block to rub the rust off.

These are not just rusting. The disks were smooth when I first bought the car, they now are grooved and kind of torn looking on the surface. I've never seen disk with this few miles fall apart like this.

Would you mind sharing a few images? Rotors will form lines in the surface with use. That is normal. It would be great to show us what you are seeing. If your V is getting poor mileage, then the brakes may be dragging/binding a bit which could explain excessive rotor wear, prematurely. But that seems highly unlikely.

Please do take the time to post a photo of your Rotor. takes a minute to snap and get up.

Also consider driving and making a few hard stops, like from 45-50 MPH to zero pretty hard, a few times, so you know you are using the discs, this will clean them up, and then let you know of you truly have pita or not.

if they look bad after that, I’d run to the dealer and have them look.

As others have said the brakes on the hybrid don’t get worked as hard as the gas vehicles, because often you are using the regenerative braking instead. Possible you got some salty corrosion going due to light use, but I doubt it. I live in a corrosive salt belt state, and brakes in my Hybrid are shiny and smooth.

Fuel economy, I’m seeing 22MPG right now, with average high temp between -5 and 5 F, and my snow tires on. Not uncommon for all cars to lose 15-25% fuel economy here in the winter, even my fully gas cars do it...Was seeing much higher in November when temps were warmer. Haven’t seen the true summer economy yet, only had the car since Oct 23.

Lets have some pictures to see. Interested by your MPG comments. Neighbor bought a Highlander hybrid. Apparently its meant to do 35mpg city/Hwy. He gets 28 normally, up to 32 on highway as long as he keeps speed down. Wonder if manufacturers are gaming the test cycle.

Before doing anything. we suggest photos first, then if you want to trust a hard brake, glaze your pads, just let us know.

It takes a minute to do this .

It could well be caused by road debris, although small, but enough to get into gaps between the pad/disc and cause something like this to occur.

About a half hour after running around in the snow.

I checked and I'm at only 2200 miles. These disk were smooth and shiny when I got the car in December. I think that there is a problem with the steel/iron these are made from.

 

[fishycomics]

you may have to ask the shop to Turn them, that is cutting a layer off, Rotors can get cut two times before replacing, shop may not want to do it the 2nd time, just keep that to mind

 

[Carbuff2]

THANK YOU for the pictures.


JMHO, I wouldn't worry about it.

Those pits will not reduce braking effectiveness as much as drilled or slotted rotors.

will you say when backing out you hear a squeal.
