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.
2008 Toyota Sienna 3.5 V6 has had piston slap since new. Toyota knows that there is a flaw in all of these engines but because there have been no failures and few complaints, they are choosing to do nothing about it. I like engines and I know that where there is noise there is excessive wear and potential future failure.
