The check engine light came on. I took it to my local Toyota dealer and was told it was the coolant control valve. The charge for this would be just under $400.00 to fix. Am taking it to another shop for a second opinion/cost.

Same problem. Thanks for the posts as I pretty much knew what to expect.
Unfortunately it sounded a little more involved than I would care to take on, so I took it to the dealer who charged $478 even with some additional discount.Flag ThisLike0 -

coolant valve = $300.00. Would have cost $400 but was getting recalled water pump done at the same time so they told me they gave me "a break".
