I bought this piece of sh*t in September 2017, this is the worst vehicle that I have ever owned (52 years of driving). This truck has a whining noise in the rear-end, with only 4310 miles on it and the "IDIOT" service manager tells me that there is nothing that they can do, " because all new Toyota Tacoma's have a whine in the rear-end". I asked the service manager to replace the rear-end and this Jackass tells me that it won't do any good, Refused. I still have the same problems with this truck, as when I bought it 8 months ago, between the dealership and Toyota, nothing repaired yet. I surely wish that for my use, that I had bought the Honda Ridgeline, my biggest mistake.

Rear differential howls/whines at 55mph, 62-65mph, 70-71mph that I can notice. Took it in twice to dealer, first time, they replaced a heat shield in the transmission, howl still there, rode with tech who acknowledged the issue, but said they have no fix and it's a common issue in Tacomas. Acknowledged it's not right, but he doesn't know how to fix it.

Plenty of documented cases of this issue, and Toyota still hides without a solution in sight. Disappointed as this is a brand new truck, and the sound is audible and very annoying, especially on the freeway.

500 miles into my new truck and it has developed the dreaded 60 MPH feathered throttle differential howl that seems to be plaguing Tacomas--it had progressively gotten louder as the miles have increased. Toyota won't recognize it as an actual problem and passes it off as "normal". It is NOT normal. I had a driveline shop inspect the third member and they confirmed that the gear pattern on the coast side is indeed set incorrectly. They recommended replacing the gear set and setting them up correctly. While it will not cause any short term problems other than an annoying noise, only time will tell if it will actually cause damage to the differential long term.
