    Lately, I’ve been hearing a squeaky noise from the front passenger area when my car’s in forward motion. Never when the brake’s been applied or the car’s in reverse. I can only describe the noise as reminiscent of squeaky coils or a bird’s trill. It’s intermittent and noticeable enough to be irritating but not loud enough to be alarming.

    I’ve checked the front passenger seat and it seems firmly locked in. The dealer checked the suspension but ruled it out as a cause. I was told the suspension did not appear to need lubrication. Moreover, it’s in the back, not front where I’m hearing the noise. After the technician was done, I accompanied him, sitting in the back, while he drove. He was unable to tune into the noise, even after I would point it out.

    I asked if it might be a matter of the seat requiring lubrication. The tech dismissed that outright as a possibility. The dealer said no other customer had ever complained of the symptoms I described. I’m unsure if their inability to connect with my complaint is due to its uniqueness, failure on my part to inspire their curiosity or the time of day, a Friday afternoon.

    While paying particularly close attention today, I noticed the noise did not begin until a few miles into my first trip of the day. It did not occur immediately upon start-up in the morning.

    As another option, the dealer suggested I leave the car with them for a good part of one day, so they could test drive it a few times. Before doing that, I’m hoping other owners who’ve had a similar problem will share their diagnoses and hypotheses. In case it’s relevant, my car is 3+ years old with less than 12K miles.

    I had the same thing happen to my car, all stock suspension. It would sound like an old squeeky mattress occasionally on bumps.

    I had this TSB done on my 2005 while it was still under the original warranty. It squeaked again on the way home from the shop, alas. However, in all fairness I must say it squeaks LESS since the service, even if the squeak isn't totally gone.

    That's exactly how mine sounds. How did you get rid of the problem? I took the "mattress" out today and the squeaking started almost right away. It continued through multiple stop-and-go errands. Then, silence on the trip home. My inability to replicate conditions for the squeaking (at least for purposes of dealer illustration) is almost as frustrating as the noise itself. The TSB is encouraging. If only my car was still under warranty ...

    I had the squeak from the passenger seat. I just picked up my car from the dealer for the 35K service. They said the squeaky seat is under TSB 0390-08 and they had to order some parts. It is related to the TSB on this thread as the service guy mentioned they order bigger pins to replace the original ones.

    Thanks for the report. It's been awhile since I checked and didn't realize there was another comment. My search of the TSB your dealer cited, 0390-08, yielded nothing. Is it different from TSB NV004-06 ("Front Seat Squeak Noise")? If your problem's been resolved, I'd love to hear an update.

    Hi TidelandProud,
    Did you manage to get your problem sorted,was it the seat or suspension?

    Rest, I'm glad to hear of your success in eliminating the squeaks. I don’t think ours are similar but wholeheartedly agree that they can be so annoying as to drive one nuts. If I’m reading you correctly, yours hinted of plastic. Mine, on the other hand, is reminiscent of metal. Emanating from the center of the seat, it sounds like sagging coils in an aging piece of furniture no longer able to absorb pressure.

    halpos4, I’ve got no progress to report in identifying culprit, though I appreciate your interest. As mentioned earlier, the dealer ruled out suspension. I have no reason to question that diagnosis. The squeaking occurs erratically and intermittently. Making it even harder to discern patterns are the low mileages that I put on the car; I don’t normally give it much of a workout. .

    A few months ago, I was rear-ended by another car. Offsetting the damage, which amounted to no more than a few superficial scratches, was a month or so of no squeaks. Just as I began to let down my guard, assuming the accident had oddly solved the problem, the squeaks returned. Arrgh! .

    With the car out of warranty and my dealer’s rate north of $100/hour, I’ve not been eager to commission work on the TSB. Also, at least one person here has said it failed to eliminate their squeaks completely. If the repair's to be on my dime, that's hardly confidence inspiring.

    I had a peep, squeak, or whatever noise going over bumps in the road.
    Went to three dealers to find the fix. The last one traced it to loose front brakes pads. They installed a shim kit and a heavy backing grease, no noise since.
    Bought the boys lunch and now go there for all my service.

    Good luck...Dan.

    Hi TidelandProud,
    The problem i had was suspension related,i knew it was coming from passenger side[left side for me of course]my local Toyota garage just couldn't find what it was,because i drive the car a lot i noticed the problem start at 180,000klm,i changed anti-roll bar bushings,tie-rod bushings and then the top shock,that particular part seemed to sort the problem albeit temporarily,yesterday 14/5 or should i say 5/14 and now with 225,000klm my dealer put a new shock on UNDER WARRANTY...Yes there are good dealers,and the problem is definitely gone,
    They inspected the old shock and couldn't find anything wrong with it but obviously when under load the problem persisted,
    It's just when you said the noise you hear is like a mattress coil,well that's how my problem started but with the miles i cover it tended to get worse week by week,i hope you get your problem sorted.

    Not to derail you process here but I thought I'd offer my experience. My '09 started squeaking about a month after I bought it. The cause was the plastic tray inside the upper glove box was not seated properly. Ever since I seated it correctly, the problem went away.
