Car Forum / Hyundai Cars / October 20082006 Sonata rear rotor rusting and pitting
I just did my 40,000 mile maintenance and inspection and while rotating the tires inspected the brakes. The good news is that that pads appear to be less than half worn out. Yes, after 40,000 miles there is a lot of material left. The bad news is that the rear rotors are rusted and pitted pretty badly. I noticed they were noisey a few times this summer when I didn't drive the car for a week or so as I was riding my motorcycle so much. I was amazed though when I looked at the rotors tonight as they are in bad shape. At this point, I'm just going to run them until they finish off the rear pads, which looks like it may take a while even with the pitting, but the certainly will need to be replaced when the pads are replaced. I've never seen a vehicle with rotors that pitted this badly other than old vehicles at a junk yard that have sat for for YEARS. Has anyone else had this problem with their Sonata? I wonder if anyone makes stainless rotors for the Sonata. The stock rotors appear to be very cheap cast iron, I'm guessing recycled iron. This reminds me of the problem Ford had in the early 70s when they had a lot of body rust-through problems which, IIRC, were blamed on recycled steel that hadn't quite been recycled enough and had impurities throughout the metal that caused rust to commence.

I figured not as most brake related items are brushed off as "wear items", but it probably is worth asking. The care is past the 36,000 mile point though so I suspect it is in just the "power train" part of the warranty now. Matt If the car sits for just a couple of days, the rotors will show some rust, but I don't know about the pitting, unless the castings were bad and had porosity, which would (or should, depending on your stealership) be covered as defective. >> Is this not still under warranty? > [quoted text clipped - 4 lines] > > Matt > If the car sits for just a couple of days, the rotors will show some rust, > but I don't know about the pitting, unless the castings were bad and had > porosity, which would (or should, depending on your stealership) be > covered as defective. I've found that my Sonata rotors will rust in as little as 12 hours in damp weather while my Buick rotors never show signs of rust even after a couple of weeks sitting in the driveway inches from the lawn. . Must be a different alloy? >> If the car sits for just a couple of days, the rotors will show some rust, >> but I don't know about the pitting, unless the castings were bad and had [quoted text clipped - 5 lines] > of weeks sitting in the driveway inches from the lawn. . Must be a > different alloy? Yes, I'm seeing much the same comparing my Sonata to my Chevy truck and Chrysler van. Something is obviously inferior about the Sonata rotors, but I don't know what it is. I'm guessing you are correct though in that it is a different composition or they are using recycled steel that has impurities in it that is accelerating the rusting and pitting. These rotors are complete trash in 40K miles and the pads aren't even half worn out near as I can tell visually. That is simply unacceptable to me.

Yes, all cars do that. My Chevy and Chryslers get a thin uniform layer of surface rust that comes right off at the first use. The Sonata makes a loud grinding noise for several stops if it sets more than a day or two. The pitting is worse than anything I've seen on a car. The only car even close was an 84 Accord I owned whose rotors rusted beyond service in less than 60K miles. By way of contrast, the rotors on my 1994 Chevy are original and have 106K and 15 years on them. Looks like Hyundai and Honda buy their rotors from the same source. Matt This isn't uncommon, Matt. I see it mostly on cars that are drive infrequently or for short trips, even though you don't seem to fall int that category. I, too, think it's a problem with the metal in the rotors. Rotors ar covered for 5 years/60k miles, but the warranty pamphlet specifically say rust is "not covered." Can't hurt to ask the dealer, though. Many managers/advisors neve actually read the pamphlet. You may wish to specifically ask for th person who knew something about the "fuel tank air filter." I imagin you'd be rather upset if someone told you it was covered, and you the made a significant outing only do find out it wasn't - Message posted using http://www.talkaboutautos.com/group/alt.autos.hyundai More information at http://www.talkaboutautos.com/faq.htm > This isn't uncommon, Matt.

I have driven the Sonata infrequently a few times this summer as the weather was good and the K1200LT was calling... :-) I don't think I ever went more than 6 days idle though as I drive the Sonata to church each Sunday at a minimum. And no comments about Sunday drivers!! > I, too, think it's a problem with the metal in the rotors.

I figured as much as I've not see rust ever covered before. > Can't hurt to ask the dealer, though. Many managers/advisors never > actually read the pamphlet.

Matt Wonder if it was a bad "batch". I,ve had 3 Sonata,s over 11 years, the latest for 5 yrs, 80,000 km and no pitting whatsoever on any of them. As you say, worth harrasing the dealers. John I don't think so. I've been seeing this for about 5 to 6 years or so - Message posted using http://www.talkaboutautos.com/group/alt.autos.hyundai More information at http://www.talkaboutautos.com/faq.htm |
