Sunroof implosion

The sunroof was making more and more noise when opening. Yesterday, when it had opened fully on the way home, it made a huge BANG/CRUNCH noise. Made my head snap up .

Tried to close it but it was stuck back, it would move ever so little forward on the passenger side, but nomovement on the driver side. Would not automatically close.

So I called the stealership right then on the cell phone, and of course they service dept is closed (4pm) already, and gee, we're all booked up this week.

So I taped the opening with a piece of plastic and duct tape when I got home, had to go on a bike ride at 6pm. On the way to the bike ride, I got the speed up near 55mph, and the wind deflector shield tried to drop, CRACK!! Loud noise again, but different from the earlier noise.

So what the hell, I pushed the close button again, and it starts closing, but a lot slower than normal, very labored, the motor was struggling so I reached up and helped by pulling the sunroof from the middle. If closed all the way.

At least when it rains today water won't get in. I have to make an appointment for next week for a fix. I will actually probably try for a couple weeks away, so I can have a damn loaner (they need two weeks advance notice of you car breaking down do give out loaners).

I want to leave my truck there, and not pick up until it's fixed, even if it takes days for parts (I suspect it will need parts.)

Keep having these little BS quality issues, and I bought amy first Toyota on the premise that they are a high quality vehicle. Sunroof, rattles(too many), brake rotors turned and replaced, radio failing. All on a two year old vehicle.

So far the only saving grace has been that it starts every day and has no drivetrain problems at all..

My sunroof did something similar. After I complained that it was making squeaking noises they "fixed" it. When I picked it up and I was testing it in their parking lot it made some funny noises and then LABORED to close. Well it wasn't able to close but luckily the service rep was still there. She drove it into the mechanics bay but all the mechanics had gone home so she was able to get it closed.

I had to bring it back the next day for them to look at it and they said they'd need to order parts. About a week later I dropped it off and it took them the better part of the day to fix it. [fingers crossed]I haven't had a problem since. I do have the 7yr/100k warranty so if it becomes a problem again, I'll just bring it in.

Sorry for all the issues you've been having. In January I'm coming up to my 2yrs and hopefully I won't have the brake issues you've had. Let us know what happens with the truck.
 
I actually try not to use mine much. I have no problems with it, but a sunroof is like an ice-cube maker on a refrigerator. It will be the first accessory to break.

Washing my T4R this weekend I was very upset to notice that all four sections of body cladding (over each wheel) is becoming discolored. It is the non-painted type. It looks like sun damage or something?
 
My sunroof did the same exact thing and I had to help it get going to close. Well I've used it a few times since and it did become progressively less labored to close to the point that it closes normal now. But I'm worried. How do I get this fixed if it is not happening NOW. I know it will happen in the future again and probably at 1 mile over the warranty time. I'm going to say something when I bring it in to be inspected just so they have it on record.
 
In on the First 10-1

Got a service appt on Oct the 3rd (the only date they had a loaner, it's going to be a base model Camry). Drop off on the first, get loaner, and I won't give it back until the truck is fixed.

If anyone is in the area of Bristol, CT, please be advised that Stephen's Toyota service is not "Oh what a feeling" . It's more like "Oh dammit!!".

Hopefully it's resolved quickly and PERMANENTLY. Toyota should just redesign a new RELIABLE sunroof for the next generation that will retrofit the 4th gen.

Those crack noises really freak me out. I've had mine do it a few times, but it's never been stuck.

The moonroof is the most poorly designed part of my car and the one thing I've had the most trouble with. Toyota really should have spent more time designing a well-made moonroof.

Sorry to hear about your problems. I hope they get fixed soon!
 
Is this sunroof problem an '03 year issue? I see that all of you here have '03 model Runners and I'm hoping they corrected this for the '04 model year! I've had my Runner for over a year now without any problmes. I did get the stealership to lube the sunroof rods on the vehicle year checkup!
 
They are the same

Same sunroofs. I feel that eventually, all of them will have similar problems. And if yours starts to make loud cracking noise when it opens, it's ready to quit at any moment.

Agreed. The service manager at the dealership said that the 4Runner sunroof is causing lots of problems. And it's the only Toyota sunroof that he can recall ever having problems.
 
I had the same problem with my 04 Sunroof. After 4 attempts at 2 different dealerships, they finally replaced the entire thing- racks, motor and glass. Luckily haven't had a problem since, but trying to get them to fix it... well it's no fun I can attest to that.
 
Mine is starting to do the loud cracking noise when you first open it and the wind guard raises up. Also when im driving and I hit 55mph the wind guard makes a noise like its trying to lower, but I dont think it does. When I was getting my oil change i had the service manager listen to it, he said that since it still opened and closed normally I shouldt worry about it (whatever). Then I said it doesnt adjust automatically anymore while driving he said its not supposed too. I of course know this is bs, but I didnt argue with him. Needless to say im not going back to that dealer again.
 
Sunroof fixed...Replaced

So, they had to replace the entire sunroof, glass, and also the motor assembly.

Their comments were that there was some "unusual" wear on some of the motor gears and also that the weatherstripping was deformed.

I had SHOWN them the deformed weatherstripping last year when complaining of rushing water noise from over my head when it rained. They said at the time that is was normal to hear water, and any that leaked through would be drained by the sunroof tray. Sheesh. They should have just fixed it the first time.

Now the sunroof is nice and smooth, and the weatherstripping is perfect all the way around (new glass). I hope it stays fixed!!! The rattle and sunroof gremlins are driving me nutz!!

Since I had arranged for the service appointment 2 weeks in advance, I was able to get a loaner (Courtesy Vehicle) they gave me a base model Camry for a loaner, for which they had to copy my drivers license, my insurance card, and take a credit card swipe. The interior windows were filthy, covered in road haze. I had to clean it to see clearly.

And the TOPPER, the service techs left dirty fingerprints in about 5 spots all over the 4runner headliner!!! GAH!!

I've gone to the dealer and complained about a grinding noise from my moonroof multiple times and to no avail. I was told nothing was wrong with it. It did have the moonroof fix when the service bulletin came out for that but these new sounds came afterwards. Perfect moonroof weather last week :) so opened the roof only to hear the grinding noise as well as strange clicking noises. Opened and closed a few more times and roof moving slowly and clicking sounds continuing. Moonroof finally gets stuck in opened position. I was able to close it by manually pressing down the wind deflector. Tried again and got stuck again. Took a closer look and noticed that it was opening and closing unevenly with one side rising up. Brought it to dealer to have speaker and some rubber parts underneath replaced and told service rep. about roof. He called me later telling me that tech did not see a problem but that he went back and recehecked and could see how it was not closing and opening correctly. Moonrioof taken apart and it seems that a cable was stretched and needs to be replaced. Brought truck in on Thurs. Was called today and told that part had to be ordered from Japan and that tech did not want to put everything back together and then take it apart again when replacement part came in because something else might be damaged. Originally was not going to be given a rental but after several strong requests, they agreed to pay for rental. (My dealer does not have loaners.) Don't know why they wouldn't since they are doing the repairs under warranty and they are not exactly sure when they will get the part. I am calling Toyota Corp on Monday. I have had recurrent problems with this vehicle. They did give me a freebie extended warranty last year but I want them to know that I continue to have problems and that this does not make up for the wasted time and loss of use of the 4runner. I should not have had to insist on getting a rental car since I don't know how long the runner will be out of commission. I do think the tech should have just put everything back in its place so I could have had my 4runner back. I don't buy the excuse that other things may break. I just don't think he wanted to put it together and take it apart again.


In addition, My NAV has stopped working at least four times. The sound in my stereo has stopped working. In order to get these to work again I need to turn off the engine and restart. When I bring the vehicle in for these problems, I am told that nothing is wrong since they can not replicate the problem. I have had to have several parts in the vehicle replaced.

If you are having problems with your moonroof or any other part of your vehicle, let them know, even if they are intermittent. Since my complaints are all on record before my regular warranty expired they are covering repairs under the original mfgs. warranty rather than my extended.

I do hope that they receive the part quickly for the moonroof so I can get the 4runner back. My overall experience with this vehicle has NOT been a positive one. I will be sure to replace this vehicle before my extended warranty expires.
