Exhaust noise. Vehicle sounds as if there is an exhaust manifold leak.
I am writing to complain about a ticking noise from the v6 motor. I've taken the truck into the dealer twice and even drove a new Tacoma from the lot. I've noticed a sound from all of the Tacoma's. The problem seems to be a normal thing for the Tacoma's, but it's very irritating.
Since day one I heard this ticking noise, I brought it back to dealer and complained about it. They test drove it and heard the noise, then they drove a new one off the lot and said it made the same noise, so they told me it was normal. After the 3rd time bringing it back for the ticking noise they said it could be the injectors or the exhaust manifolds. Then I called the Toyota corporation and complained about the ticking and they had somebody from the dealership call me up and take him for a test drive and he did not hear the noise he told me I must have especially good hearing at that frequency. What a bunch of crap!.
