Hi All,

I'm new to the forum so please pardon any rules or etiquette I'm not adhering to. I have a question that I'm hoping for a quick turnaround.

I have a 2011 IS250 and I've been experiencing an issue since about the time I bought the car a year ago: when I drive my car after it's been at rest for a few hours (usually in the morning after being parked overnight), I hear a very noticeable metal-on-metal scraping noise when I am braking for the first minute or so, and then it goes away. It's usually worst when it is wet outside, like raining.

I brought the car to the dealership several times and they couldn't figure it out. This last time I brought it in I thoroughly explained the problem again and they kept it overnight when it was raining and their explanation is that rust builds up on the rotors b/c it is wet outside and the scraping noise is the brake pads scraping away the rust. There is nothing they can do about it.

Does this seem like a reasonable explanation? And if it is, should I make a big deal and try to get them to replace the rotors?

Thanks everyone.

 

Thats normal. It didnt happen to your previous cars?

 

Nope. And it didn't happen this morning in the loaner RX they gave me even though it rained all night.

 

Sounds like a normal characteristic of the IS250. The rotor compound, which is softer, is different than the RX350. Because of the softer compound, in the future when your first/second brake service is due, the rotor may need to be replaced, but that's a whole different story. Anyways, you should try getting an IS250 loaner and the comparison would be more fair.

 

Weird. All of my cars have done that occasionally.

 

Unfortunately, that sounds like a common problem in a lot of newer cars (after rain or a wash). My wife's VW does the same thing. It usually stops after you've driven and stopped for about 30 minutes.

 

It's normal. I notice it when I wash my car and don't drive it til the next morning. The first time you use the brakes it cleans the rust off.

 

I get the same noise and made a thread a few months back that included a video/audio of the "issue"... General census was that it was normal. And I've gotten similar responses from members off other forum who drive various sport cars.

 

I keep mine in a garage so it only happens after I wash it. All 3 of my IS's have done this so I think it is normal.
