This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
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!!
I bought a second hand 2007 Toyota Sienna le in June 2009. The vehicle had about 49,000 km. I noticed that vehicle had produced unusual noise when started at cold. It sounded like diesel engine. I took a vehicle in to a Toyota dealer and they attempted to correct the problem. Apparently, there is a tsb issued on this problem. Although I appreciate the dealer's honest effort in correcting the problem, the noise is still there when engine is started at cold.
I have a 2007 Toyota Sienna. When the engine is cold and started I get a noise that sounds like a lifter problem. Although the weather will effect the intensity and duration of this noise it is always there. The Toyota dealership I took it to had a factory engineer come out and he heard the noise and said it was normal and attributed it to "piston-slap". at this time they are telling me there is no repair for this condition. They acknowledge there is a noise but they say they can do nothing about it. This noise developed approximately around 20,000 miles on the vehicle. Other Sienna's that acquaintances own do not have this problem. Some mornings when it is cold out the noise is so loud it turns heads as I drive down the street. Evidently this is a problem that Toyota knows about but refuses to fix.
2007 Toyota Sienna made a pinging sound when first starting the vehicle. Consumer states that the dealer stated that this is normal when the engine was cold. Dealer called it a piston slap. Finally dealer stated the vehicle had a problem.
