Water may leak from heavy rain, from the sunroof region into a part of the roof, leading to water leaking from the interior microphone above the driver seat. Seems to be a common issue amongst 2016-2017 RX350-€™s but no recalls. This is a safety issue given that the microphone is where the water leaks to, compromising other electrical systems. In addition, water builds and wets the headliner causing mold/mildew smell, possibly leading to future mold build up which is harmful to health. Lexus in Houston inspected and stated a new sunroof is needed, which is costly, although this is a manufacturer flaw.

While driving with the vehicle on cruise control, the vehicle went from 75 mph to 0 on the interstate. I was able to coast into a nearby rest area. At this point the car would start, but none of the systems would operate. The dash displayed several system failures to include the hybrid system, check engine, pre-collision system, braking system and all-wheel drive system. This is a brand new vehicle purchased from a Lexus dealership. The milage at the time of breakdown was only 883 miles. The dealership labeled this event as a catastrophic failure, but I have received no valid explanation as to what happened to the vehicle.
