Hood Vibrating

Short of reading all 57 pages... Has anyone sprayed rhino liner or other bed liner to the underside of the hood? Should make it alot stiffer.

I'm planning to bed liner the underside of mine over the week of the 4th. Btw, I'm not talking using those junk spray cans, I have a real bed liner gun like the bed liner companies use.

 

** Fixed **

Traded my sport hood for an OR hood -- Unknown to me, non-scooped hoods have these vibration problems. Noticed it right away after the swap. And going back to the dealer was now not an option.

Following the suggestions of others on this thread, I used 3M 04274 NVH Dampening Material (200 ml -- Amazon) and applied it in a similar fashion to post #571.

also, if instruction manuals give you peace of mind:

Overall, worked perfectly -- vibrations essentially eliminated and no deformity to the hood exterior. 3M 04274 was easy to work with. I applied it with the hood still on the truck -- make sure to have lots of extra paper towels. And cover the engine with a blanket (just incase). If things go smoothly, careful application only takes 1-2hr. (200ml was enough for me, but I used it all). I left the hood fully open for approx. 3hr after application and then gently shut it. Unexpected plans forced me to drive about 16hrs after application, but it seemed to do the job by then.

From reading the thread, this DIY-fix seems much easier than going back to the dealer.

Hope this info helps!

 

So it's just the non scooped hoods having this problem ? Thanks .

 

Yeah, I believe so.

 

18 tacoma limited here. Noticed several sections of the glue seperating on my hood at 5K miles now..Called dealer and got the "First I've heard of this" answer

 

Show him this thread, and how far back the topic goes.

 

Took it up today to have them check it out..More glue had let loose than I had realized. They are contacting Corporate for instructions. I really hope I'm not without a truck for a couple days for this

 

I was without my truck for a week while they had a body shop add more glue.

It was like pulling teeth trying to get them to admit that it wasn’t normal.

 

It is normal. The probem is it shouldn't be happening but anything tougher would cause the thin hood skin to crease around that stronger stuff.

 

Have had my 2020 for a few days just broke 200 miles, already have this issue.

 

For what it's worth...the Gen 2 Tacoma's without the scoop had the same problem. Not as pronounced on the Gen 2's because the hoods are not so darn long. I bought a 2018 Sport for this very reason (and besides that I don't need crawl control or a locker). Oh...my wife has had three Gen 2 Tacoma's both with and without a scoop so I really do know what I am talking about.

 

Mines been doing it since I bought it, doesn't really bug me. I have less trust in the dealer not making things worse than worrying about it at this point. I got a free 8 year extended warranty from the last time they screwed up so I'll just wait this one out and see if it leads to anything else, otherwise it's not a problem to me.

 

Even though this "fix" is for a Mazda, it is probably the best/safest fix. I don't think that Toyota really wants to admit there that is a problem.

On a side note it looks like Mercedes is recalling 750,000 of their cars because the glue holding the sunroof on gives away and the sunroof flies off.
So other manufacturers have worse problems.

I just got my truck back from it’s 10k service and I had them look at this exact “problem”.

They didn’t give me any run around excuse at all, they have seen it before and said they filed a claim with Toyota and are waiting for an approved fix.
My technician said he would love to just add some glue or foam in the gap but they are not approved by Toyota to preform such a fix. He recommend finding a DIY fix on the internet while we wait for a response.

Shitty but that’s just my two cents if it’s worth anything!

 

Lame, keep us posted.

I'm undecided whether to have the dealership mess with it or DIY.

I feel like I shouldn't have to be gluing the hood together on a car with 200 miles on it.

 

Got a call from dealer. Toyota approved the fix so my 2018 Limited is headed to a body shop to be fixed once they get a loaner back in for me. I have to wonder if this is caused by them not having a hood liner anymore and the heat breaking down the flutter foam? Anyone with a hood liner have similar problems?

 

Pretty sure its because of the thin sheet metal of the hood to save weight. A thicker top would allow a more resilient adhesive that wouldn't let go or cause the top to get creased. Of all the suggestions bed liner or high temp undercoating seems to me to be best option after having added more NVH.

 

I just bought my 2020 OR in November. 1,500 miles now and have noticed the hood vibrating on the highway since the day I drove it off the lot. Guess I'll be checking under the hood in the morning...

Blew a tire at 300 miles, cracked my windshield at 1,400 miles, and now I find this thread

 

Same here, I’m happy but sad that I found this thread. I have a 19 OR with less then 2k miles. I looked under the hood and saw this shit.

I’m in San Diego, anyone local have a dealer that has dealt with this successfully?

This is my primary gripe with the taco right now. 40k truck shouldn’t have this issue.
