Folding Roof Reliability

regardless, doing it at high speed, i just can't see why it makes sense at all. just imagine if (when) it snaps and hit anything behind you. you will be paying for BOTH your car AND the ones behind you

Another reason that you won't see a hard top convertible do its roof operations at higher speeds is simply because we have the enormous trunk lid that inverts and becomes rather unaerodynamic during roof operations. If you wanted the SC430 top to operate at 30mph, the trunk lid mountings would have to been severely reinforced to handle the wind forces. I don't think the Porsche Boxster or other soft tops would suffer from that problem.
BTW, there is a bit of hysteresis built-in to the speed control roof lock-out function. If you're at a stop and slowly accellerate, you'll be able to continue operating your roof till your car hits the 4mph mark, at which point the roof operation stalls. You will actually have to come to a complete stop again (0mph) with a dwell time of at least .5 seconds and reassert the close or open pushbutton for the roof operation to continue. Yeah, I've tested it out for fun when I got the car. Yeah, I'm nerdy like that.
No problems with my roof so far, hope it stays that way.

since we are talking about roof reliability, there was an old post on someone's roof not closing the same amount on each side. IE the gap on the passenger side was a tad bit more than the driver side? I can stick my pinky in the crease on the passenger side and not the driver. Should I take it in?

it shouldn't do that right?
I have a 2003 SC430 and when I bought it in Aug. 2007 (I guess it would be a 4 year old old), the top was down and wouldn't close the same night I took it home. It went half way up to close, but wouldn't finish! So I just had to put it back down. I took it back to the used car lot for them to fix. Fortunately I had a 1-month warranty when I bought it.
A few months ago, I noticed a chip on the paint right in the middle of where the trunk would touch when it lifts as it becomes a convertible. Do you think the trunk lifting up is scratching it? I'm not sure, still trying to figure that one out.

". . . where the trunk would touch when it lifts as it becomes a convertible. . ."
I don't understand a lot of this. First, the car does not "become" a convertible; it is a convertible because the top can be on the car or or removed and stored. Secondly, there is no such spot "where the trunk would touch" the top. The parts are designed to not touch, and mine never have, so I'm not sure where that spot would be.
If you search here, you will find virtually no posts of tops being scratched during the raising and lowering operation; this is unusual and clearly not normal.
Finally, you ask us if we think the trunk lifting up is scratching the roof, but it's a little hard to see it from here. I recommend you have somebody operate the top several times while you observe (and take pictures for the service technicians) to see if the trunk lid is touching the top and where.
I can say that from reading the posts here that this is unusual, but no one here can say what caused the chip on the roof of your car. (I've been operating the top on my car since April of 2001 without incident.) Unless you observe the malfunction in action, (and document it) you cannot get it properly repaired.
Also, we might be able to provide more info if you post a photo of the "chip" here.

Yea, the location is sorta hard to explain without some pictures. Here are the photos:



I had looked myself when I had someone drop the top and it seems like the trunk does touch that area, but I can't tell if it's scraping that area. The chip wasn't there when I bought it. It happened a couple months ago. Do any of you have this chip?

I've got a 02 that I haven't had for long. One morning when I tried to put the top down the trunk opened, the top started to unlatch and from there on it wouldn't do anything in either direction. Manually closed the trunk, retried with same result. Thankfully the dealer I bought it from had it fixed. A couple of motors were replaced.
mayonnaise, between this and the thread you started about the trunk being hard to close, it's sounding more and more like maybe your car has taken a hit in the rear some time in it's past. Something's probably out of alignment back there. One problem causing multiple issues.
