The description is too imprecise. If it's a 2012 I suggest you take it to the dealer and have it checked while it is under warranty.
Sounds very much like the speed switch may be faulty, or the ocntacts need cleaning.
What is the roaring noise from a 1999 Toyota Camry XLE at speeds over 35 ? Sounds like it is coming from the rear.
could be a bad water pump or a loose alternator belt
Sounds like heater core is leaking
If it is the illuminating lights you are referring to in all three instances, it sounds like either a fuse to that circuit has blown or the bulbs themselves have burnt out and need replacing.
I have wondered the same thing, sure sounds like the highlander
Stock Toyota exhaust system.
sounds like you have a cracked head
This sounds crazy.......your gas cap must click when you screw it on. After you have tightened your cap, disconnect your battery and wait 20 seconds and reconnect it. Your light should now be off.
To muffle the sounds of the engine /exhaust coming out take it off and see how it sounds!
It sounds like it is working fine except in reverse, maybe reversing the wires will do the trick.
Sounds like the AC drain is plugged. The line exits outside on the passenger side ; when plugged with dirt, they back-up and drip into the passenger side of vehicle. If plugged, spray compressed air up drain to clear out.
