CarComplaints.com Notes: Toyota says the 2015 Sienna has been redesigned with "more swagger." Let's hope it's also been redesigned with less seat noise.

2015 Toyota Sienna limited defective brake system design. The consumer stated Toyota has done nothing to fix the inaudible turn indicator. The consumer stated the issue was whether or not the braking system could support towing an additional 3500 pound load as advertised. Based on his experience of having warped front rotors that required replacement at 19,242 miles, there was a serious front and rear brake design flaw. Updated 04/14/2017
