In the last 8 years I have bought two Toyota hybrids, plus two for my daughter. In 2016 I bought a low-mile 2014 Avalon hybrid and just 6 months ago I bought a 2010 Lexus RX450h. With Toyota's legendary reliability I wouldn't expect you'd find any issues with the hybrid battery pack. At the same time I bought my 2010, I helped my daughter find a 2016 Highlander Hybrid. She moved up from a 2006 Highlander Hybrid I bought for her in 2015. So that's four hybrids, no issues. Now, with a $35k budget, you will find lots of options. Me personally, I like the exterior styling of the 2010-2015 RX, but the 2016 and newer has much better electronics (screens, interface, etc.) and interior styling. I would aim for this model, but know that pricing is just now coming down into that upper end of your budget. I would personally aim to get the lowest-mile example I can find between 2014 and 2020. Of course condition is all dependent on where you live, things may be different if you live in the rust belt, Florida or on the west coast. Good luck!
