Toyota Prius yr/mdl 2009/1224 a I have attempted to have the following checked with Toyota of hickory where I purchased the Prius and was told that I needed to allow the battery to heat up before trying to place it into reverse or drive. My Prius will go into n, it will lock all doors and windows and not go into gear or start. I have been locked in the car during this past summer without air and I attempted several times to cut the car on and off before it would go into gear. This is very horrific to say the least. I was at lake norman Toyota yesterday and was told this was a common complaint. Yet no one offered to take this car in and check for problems. From the day I drove off the lot until now this hybrid gas/elec sedan has given me nothing but trouble.
