Purchased my unicorn 2017 super white Tacoma TRD Off-road DCLB in February 2017. Yes, 1month ago. Took 2 months to find her and had 3 dealers looking for me. I didn't want to pre-order but I wanted it loaded, crawl control, roof rack, long bed, tonneau cover and had to be super white. Almost right away I was noticing a delay in the reverse to drive and drive to reverse on cold start and noticed strange shifting patterns during driving. Took it to the dealer with 300 miles on it and waited 6 hrs to have the latest and greatest TSB Rev1 completed and the transmission fluid checked. I don't notice the delay between reverse and drive much any more. I'm still having strange shifting. It feels like it looses power when going up a hill then goes again. When I'm slowing down it feels like the brakes go out then come back or the transmission is downshifting with a delay and the brakes are lost for a second. I have something else I'm now noticing. I was driving home from work a few days ago and after coming to a complete stop it felt like the person behind me bumped my truck. I pulled over got out and checked my bumper. Nothing noted. Today I had to drive somewhere and the street had lots of stop lights. I stopped at one and Again I thought the lady behind me hit my truck...I thought what the hell, pulled over, got out, nothing. Kept driving, stopped at the next light, I felt it again this time no one was behind me. I started to pay attention. After coming to a complete stop maybe 1 second later a clunk, jerk or bump happens and the truck feels like it's pushed forward. I immediately drove into Toyota. The service manager knew exactly what I was talking about. He said one of his mechanics has a 2016 that does the same thing. He said I was the third person in the last few weeks to come in for that issue. He said they would check the truck out and they did. 4 hrs later Rechecked the Transmission fluid, checked to make sure the TSB was current with the latest and greatest. He told me sorry there is nothing more we can do at this time. They said they called corporate and started a case number for me and would get ahold of me as soon as they had further info. I have been to the dealer 3 times now, Once for 6 hrs once for 4 hrs and once they kept it over night 2 days. 4 days of loving my truck lost. I have 600 miles on my truck. This is the first brand new vehicle I have ever purchased and was... WAS... so excited to own something no one else had owned. Something NEW! I really hope toyota figures out what is going on with my transmission. I don't want to give up on my unicorn Taco. "Tacorna" But... Im getting close!!!
