We bought 2 ,2016 Tacoma double Cab TRD's. A TRD Off Road and a TRD Sport, (one in November 2015, one in January 2016) Both of them have a stumble, miss, lack of power getting on the freeway until you get into the throttle enough for the truck to take off. At that point the guy next to you thinks you are trying to race him on the on ramp. LOVELY!! There are 3 distinct power loss areas while accelerating, and using the ECT power changes it a little bit but does not make it go away. The engine will stumble and miss with a complete lack of power until it leaves that RPM range. We have a neighbor that has a 2016 Tacoma with exactly the same problems.
Also both trucks will shift into neutral when going from reverse into drive. They shift to drive for a half second, shift out of drive, and then back into drive after a full second sometimes a second and a half delay. One truck harsh down shifts while coming to a stop and then will down shift again after it is stopped.
I have 170000 miles on a 2006 Tacoma double cab TRD Prerunner and it has down shifted like that its entire life with no ill effects. It drives and runs beautifully still so we are not as concerned with that. It may be normal for these transmissions to shift like that. The lack of power/engine miss/engine stumble is not acceptable though. If these were not a new trucks we would guess the throttle position sensor was bad or the the mass air flow sensor has a problem. We have diagnosed and repaired drive ability for many years. It does not feel like a trans problem as it seems everyone else wants to point at. Too much shifting, down shifting, and shifting around is all part of the new drive ability strategy, to keep the engine in the proper power range, thus obtaining the most power for the least fuel. That all makes sense.
We had a chance to drive a Press Vehicle Tacoma, direct from the factory, and it had none of these problems and drove beautifully. We have had both trucks into the dealer once already for the drive ability problems. They have no idea what the problem is and have started cases on both. We know that there is a problem and hope that Toyota has not tied their hands with the EPA emissions statements they have made. Has anyone else come up with a solution?
