| Description of the problem | Purchase a 2007 toyota sienna minivan in december 2007 with almost 20,000 mile in it. After purchase notice that when engine is cold it sounds like a diesel engine until it warms up. Also notice what feels like a slip in the transmission in lower gear. This happens if following behind someone and they turn u need to slow down. When u accelerate to get back up to speed there is a delay or a slip before transmission engages, complained with the local dealer (andy mohr toyota) where purchase from. We have complained since day one of ownership. Toyota dealership states that the vehicle has a memory transmission and learns your driving habits. Well me and my wife don't drive the same and neither does anyone else. No people drive the same and why would someone make a vehicle like this. They also stated that there is no fix at this time. Just trying to blow me off. As for the engine slap when cold they told me it was the exhaust heating up. Now i am no mechanic but let me tell you that is not an exhaust clapping up while heating. Called toyota usa and file a complaint after a year being pissed at what we spent and how unhappy we were. They set up a third party arbitration and a person from toyota. We met at the dealership and i voiced my concerns. We even went on a test drive so i could show them what it did. What a joke that was. The person from toyota explained to me the vehicle was doing exactly what it should be doing. ( the delay in the transmission to me seems to be another toyota problem that they don't want to acknowledge and im just crazy.) i have never owned a vehicle that did this. I guess we will need for some people to get rearended and killed before something is done about it. Nothing came out of it and now we are stuck with this expensive van that's a heap. Purchased toyota for there reputation and what a joke. Never again will i do this. I will sure research before i purchase my next vehicle. Toyota's a joke don't buy!! |
