2013 Avalon Hybrid Seat Lump
I have read other threads about recent model Avalons having an issue with a hard lump in the center of the driver's seat, and I really didn't test drive this model extensively before I bought it since I was a previous Avalon owner. At first, I seemed to be the only one feeling this hard, sharp lump right in the center of the driver's seat, but then a Toyota tech who was a little more in my larger weight class sat in it and immediately felt the same lump. After reading posts on here, I called Toyota Customer Care and they opened a case for me (case 1306243017) and I took it to Freeman Toyota in Hurst, TX. The dealer sent it to the upholstery shop, who took apart the seat and found that a blower motor housing for the heated/cooled seats was mounted so it protruded upwards and there was only about an inch of padding between it and the leather seat cover. So thinner people weren't feeling it, but us heavier guys certainly will. The fix, as reported in other Avalon posts, was adding another layer of padding over the motor, which does not interfere with the heating/cooling functions, and solves the problem. The service manager said they would need to send the pictures they took and other paperwork to Toyota to associate it with the case I opened. I hope this helps anyone else having the same seat issue.
