Electrical System problem #1

*driver-side entry failure = primary access point compromised * could trap occupants if internal handle fails or after an accident * emergency responders rely on driver-side access first * this is not normal wear and tear—it’s a safety-related failure.

Electrical System problem #2

The electronic screen on dashboard that displays map, hvac, etc. Turns pink then black and disappears for several minutes. One then has no control over the various functions displayed on the screen. I've done a hard reset by disconnecting the battery for several minutes. . . To no avail. Thank you.

Electrical System problem #3

The vehicle sustained water damage due to hurricane ida in September 2021 and was repaired at the dealership. In February 2023, the battery needed replacing for a third time since then and I was told that the front and rear carpeting was soaking wet, again, and it was due to the moonroof rails being clogged. The vehicle is currently at the dealership being assessed and repairs should be borne by the dealer/manufacturer; not the consumer. If this is specific to my vehicle only, then I have a lemon. If it has happened to others, then it should be recalled.

Electrical System problem #4

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.
