I have this same problem with my 2002 SC 430. Had it back to the dealer 3 times, but they could not identify the problem. A nuisance item. Anyone else with this problem?

I also own a 2002, I have been through 4 sets of tires. I have over 115000 miles on the car. I recently bought the latest run flats by Bridgestone at the tirerack.com on line. These have made a substantial difference in the ride quality and the handling. I get around 25,000 miles per set of tires. There are many spare doughnut tires and mounting kits available from the dealer as well as on e-bay. They just take up too much room for my liking. I often carry a bicycle and golf clubs in the trunk and do not want to lose the storage space.

Golf clubs!!! a full set with bag?
Oh yeah, I took off the run flats and it was the best thing I could have done. I might need to call AAA for a tow if I get a flat but the improved ride is woth the risk. My dealer is storing the run flats (for free) in case I ever change my mind.

why did you have to replace your power steering pump???? I am actually having a noise issue with my 2002 SC430 & thought it may be related to the power steering pump but I have no steering problems. My engine sounds like an airplane when I accelerate and I hate it, what do you think that could be if you have any ideas.

The reason your engine sounds like an airplane is because what makes an airplane sound like it does is the propeller. Your radiator fan blades are like a propeller and when they are on all the time they will really roar. The fan clutch should disengage when the engine (and forward speed) rpm's increase as the cooling air is being provided by the forward movement of the car. The radiator fan is only there to provide cooling airflow when you are sitting still or moving too slowly for the normal source of cooling air (provided by forward motion) is insufficient to properly cool your radiator. Check the radiator fan clutch - I suspect it's locked up and never releases as it should. When your engine is cold (AND NOT RUNNING!!) you should be able to spin the radiator fan fairly easily only noticing a slight bit of resistance. If you can't spin it, or it is very hard to turn, it is locked up and will need replacement. This is not an unusual thing for a 5 year old car. It's also not a REAL expensive fix.
 
That's what it sounds like to me, but there could be other things causing your problem as well. This just seems to be the most likely, based on what I read in your post.
 
Good Luck on this,

I replaced my wife's 2006 OE run flats with Michelin Pilot Sport PS2's. She tells me that it made a big difference. This particular tire is OE on several other makes (including the Porsche Boxter) which made me think they ought to be pretty good. They are.

Re: windshield cracking? [murph33] by marishka

I have a 2004 SC430 and just purchased my fourth (4th!!) windshield. The first three were covered under warranty and there no visible pits or pocks on the windshield.
This last one had a tiny chip from a flying rock, but that shouldn't cause an entire windshield to crack. I think it's a design flaw that they don't want to admit. I notice these windshield cracks always occur in summer, always in the same place (behind the mirrir in the top center) and I suspect it may be due to the cold air inside the vehicle and the hot air outside. Also on my third set of tires at 50,000 miles. Looking forward to the day my lease is up. As much as I love this car, it's become a money pit.

(sc06) same thing happened to me 2 weeks ago! I heard the stone hit the windshield but didn't see any damage. upon returning to my car a couple of hours later I sat down and right there in front of me was the crack shaped like the letter L from the top of the windshield down and to the right. the dealership service writer took a pencil point and followed the outline of the crack, and there it was right at the top a space the pencil point fit into (the point of impact) the explanation was that the perimeter of the windshild is weak due to the lack of any framing holding the glass and with expansion and contraction due to temperature it cracked. so for both our sakes if we are going to be pelted by stones please let it be in the middle and not the outer edges.

Top Down, Windows Up? by rlejr66

Hey SC430 owners, quick question . . . . .do you know whether you can put the windows up when the top is down? Just wondering. Looking at buying an SC soon and that was just something I was thinking about. You quite frequently see BMW's rolling around town with the top down and the windows up. Thanks in advance!
