I took my 2016 Tacoma in about a month ago in response to the recall letter. I was informed that there was just a "smudge", that it was not leaking appreciably, but it should have the gasket and fasteners replaced. Catch 22 - no parts and no idea (weeks to months) when they would be available. They offered me a replacement Enterprise car which I refused since there is not (yet) a leak. I also informed them that if needed I had to have a truck with tow package, not a car. They told me I could get a truck only if I used it for business. Otherwise, I did not "need" a truck. I responded that their salesman did not tell me I did not need a truck when I purchased is less than a year ago. I also confirmed by calling Enterprise that they could provide a truck, but they cost more than a rental car. Long story short: Multiple complaints to Toyota customer service, multiple phone conversations with the dealer service and parts supervisors, complaint to NHTSA for non-compliance in a timely manner, and four complaint back and forth exchanges with the local BBB, plus advising the dealer that if I did not receive a promise to provide me a truck, not a car, should mine actually start to leak, I would voice my concerns on the local Facebook and other social media sites. I also advised the dealer that if he could not get parts he could then pull the differential from one of the new Tacomas on the lot and replace mine, or order a complete new differential and replace mine. (New Tacomas are rolling off the assembly line daily with non-defective differentials, so they are obviously available). Finally received an assurance, through the BBB, from the dealer that if my truck needed to be taken out of service, I would be furnished a truck, not a car for the duration. I accepted this response from the BBB, and an apology from the dealer, and decided not to go the social media route. As of August 3, 2017, the dealer still has no clue as to when parts will become available. From my experience I would recommend insisting upon receiving what we should have been offered in the first place - an equivalent replacement vehicle while Toyota decided to put sufficient resources behind this problem to get the parts out quickly.
