My truck started having a vibration when driving around 45-55 mph. This problem first became noticeable when it had about 115,000 miles on it. Over time the speed that the vibration became noticeable at gradually increased. By 125,000 miles on the truck, it was vibrating hard between 60 and 70 mph. The dealership determined that the problem was that the drive shaft was out of balance and that it had to be replaced. They replaced the drive shaft, but this doesn't seem like a problem that should creep up with that relatively few miles on the vehicle, and I have read that if the drive shaft actually fails, it can severely damage the vehicle and potentially cause injury.

60,000 miles. Three years ago the airbag light came on. We brought it and paid for diagnostics but no answers. Now the check engine light and track off are lighting (not related to first issue) and the truck is in slowdown mode. We replaced the gas-cap but it didn't fix the issue. Disappointed in what used to be a quality company.

During normal driving, the check engine light and traction control off light came on and truck immediately went in to limp-home mode. I had it scanned for codes at the local auto parts store and it came back with p2440 and p2442 which seems like a common issue with a valve in the secondary air injection system. I quick google search showed that some 2012 tacoma owners are getting this covered under a special warranty extension, so I puttered over to the toyota dealership expecting to hear the same story, but they are telling me the ECM computer is bad. Which I am trying to get clarification on since I can't find any ECM failure issues for this make and model year.
