Ive got a 2010 4Runner Sr5 with 12000 miles. About 1000 miles ago I started to notice that the lumbar support on the driver side was kind of crunchy. I can feel it basically give way under my weight. The best way I can describe it as a crunchy feeling in the actual lumbar support when press back. I only way 175lbs so I dont believe its an excessive weight/pressure issue. Anyone else experiencing this?

I weigh 200 lbs and have the support fully extended....no crunchy feeling at all.

If you need the support, take it in...it should be under warranty.
 
I have a similar issue. I bought my 2010 Black Limited in June and around October I started noticing a "crunching" in the lumbar support. I keep my support about half way to full. It occurs usually when I'm on a bumpy road and is not something that happens often. However, its enough to hear/feel it when it does happen.

A.
 
Mine's doing it, and I reduced how far it comes out, which seemed to help.

But I'm over 3 bills...so I can make most things "pop and creak"...:frog:
 
I've had the same problem. I have 2500 miles on mine and started to notice it about 1000 miles ago and it seems to have gotten worse. I like to keep mine fully inflated, but that should not cause the support to be "crunching". I have an apointment for the 10th of May.

Has anyone with this problem taken their vehicle to the dealer and gotten this issue addressed?

Yeah, It took 2 trips to the dealer but they replaced the entire seatback. It started crunching not long after I bought it. Thought it was just me or something. They found that the bar that pushes out as the lumbaqr support was broken. Demand it be fixed and it will be.

My 4runner's lumbar started "crunching" almost immediately and been getting worse, i have about 1100 miles on it. I guess i will be going to the dealer this week sometime. Thanks for the info.
 
Mine is doing the same. Had the dealer look at it last Friday when I took it in for for 5k service but they couldn't duplicate the crunching and said they would have to take the seat apart to look for what is causing it. Not too excited about that. It's pretty consistent and annoying though.
 
As far as I know there is no TSB for it. My dealer told me the same thing that they couldnt duplicate it and would have to take it apart to figure it out. They called me a few days later and told me the new seatback came in and to bring my truck down to replace it. Not sure what happened to the take it apart and inspect it thing but Im OK with that. They replaced my seatback, stereo and di the tranny TSB in half a day.
 
Subscribed. Do let us know the results. Im about to upgrade the interior with aftermarket Gray leather and Id like to get this fixed first.
 
I went to the dealer and informed them of this problem, they initially claimed they could not replicate the problem. So i went on a test drive and was able to get the technician to admit that he could feel the crunching/popping, at which time he agreed that it was unacceptable. The service manager stated that they are ordering a new seat(i assume it's just the seat back), and that the new part should be there in 2-3 days.

So hopfully after the seat back is changed the crunching/popping goes away.

Nicely done, same happened to me. Since having the seatbackreplaced no issues like before. About 1k miles so far on new seatback.
 
Same Problem - Service Department Said It Was Normal

I have the exact same problem many of you are describing in this thread. Posted in another thread and was referred to here. I took it into my local dealer who said the crunching was typical for leather seats when I could make it clearly do it while they were there. How did you describe it to the service department so I can communicate with these guys. Like you, mine is in the lumbard area of the driver seat. Not always, but many times when you place weight on it, you hear the crunching sound. Annoying, so I want to get it fixed before the 12,000 miles at which time I will be out of luck.

Thanks.

I have a Trail and it definitely is not caused by the leather as I have cloth seats. I like the idea of putting the service manager in the drivers seat and going for a ride with him for as long as it takes. They will definitely feel it. Thats my plan when I can get back to the dealer.
