Anonymous A., FL (2018 Lexus RX 350 3.5-L V6)"Air conditioning blows hot air. Has happened 3 times & been to dealer twice. Unfortunately it usually fixes itself after car turned off. Once this didnt work, but when I took it to dealers it was working fine?They think its a switch but cant be sure. They dont want to charge me for repairs that dont fix the iisue.Ive been told to bring it in when its not working. Not an easy feat since it happens on long trips on hot days!! Annoying"

"Jumps from Bluetooth on Apple iPhone to Alexa or other system. Lexus won't upgrade the software, so we're stuck with their lousy software. Also, won't offer Apple CarPlay."
Anonymous A., MI (2018 Lexus RX F Sport 3.5-L V6)"Bluetooth connectivity pairing is poor at times. No software upgrades from Lexus. I wouldn't buy another one because the Bluetooth works better in my 2002 Toyota Corolla LE upgraded JVC radio for $79 than my Mark Levinson stereo for 5K option. Worst problem is the system jumps around. Playing music from my iPhone and it jumps to Alexa or other systems."

""The thermostat was stuck open and had to be replaced. It was creating a lot of issues when faulty, e.g. deactivated AWD system, ABS, traction control, even the parking sensors! This is ridiculous, as the thermostat does not really affect the function of those systems. Possibly an effort of Lexus to have you go to the dealer...""
