In motion, when I let up off the accelerator to assess traffic, such as at the top of an on-ramp or other merging situation, then I decide it is safe to merge, and I press the accelerator, the vehicle stalls briefly before "catching" and accelerating. The engine doesn't sputter or cut off, the vehicle just sits still as though it isn't getting gasoline. I've had a few close calls when attempting to accelerate and merge into traffic. This isn't a gear down-shift/up shift type thing...just a stall. It's not every time I slow down to coast, then decide to accelerate, but sporadically. I've had the van checked by the dealer and they couldn't find anything. I was told it's a "computer thing," with the computer getting confused because to doesn't know whether I want the van to coast to a stop or to accelerate, and "the computer gets confused." I don't have specific dates

This is the second time I had to replace my transmission in my sienna. Each time it happened, I was on vacation. The first time I replaced it was less than 2 years ago, april 2014. There was an issue with the car shifting hard and humming on acceleration. Luckily I made it home and was able to fix it. Spent $1, 404.43 which was 30% of the cost, toyota paid for 70% of it. Now march of 2016, the car lurched, was smocking and slowed down while I was on vacation in the middle of the road. Luckily I was able to get it to right outside of the hotel room. Paid towing to get the car to an overnight location, mike erdman toyota. Unfortunately, they were not able to fix it within the week that I was on vacation. I had to come home and drive back to 224 miles to get the car. This time, I am paying $3600.00. I saw another complaint similar to mine on this site. Unfortunately, I will have to get rid of the car because I am afraid for my safety. When a car stalls on you on the turnpike or in the middle of the rode, it is time to cut your loses. I am very disappointed because my family have been toyota owners but will now have to look for a new company.
