1. Ignition System: While driving the key in the ignition lock came out loose! Exremely frightened and managed to pull the car over to a driveway. But, the car could NOT be stoped using the key fob. Key will not work to stop the engine. Very unusual and unexpected incidence. 2. Lighting system switch: Suddenly the knob of the light switch came out loose with a plastic shaft and will not turn on the light. Very unsafe while driving and it became dark due to storm and rain, and I wanted to turn the headlights for safety. I beleive it is a manufaturing defect and causes severe safety issue.

Latest RX400H lighting complaints
I have had to continuous issues with my vehicle since I became the owner of it. #1 The headlamp gets very foggy. Every 2-3 months I take it to the car wash, they pop it out and clean it. I get this done because the lamp looks very dim while I am driving it at night and it makes it difficult to see the road. This is a safety issue. The second issue is that the dashboard is heavily cracked to the point where my son is able to pick off pieces and tries to put it in his mouth. I am afraid of what toxic chemicals...

the cracked dashboard is exposing me and my child to. I called lexus to get these repaired under the warranty enhancement program and they told me that both of these are now 1 year past the warranty. I have been the owner of this car since 2017 and I never got notice of either of these warranty enhancements. Before that my dad owned it and he also never received notice. I have filed a case # with lexus [[redacted]]. They now tell me there is nothing they can do and I will have to pay out of pocket for issues that have been existing for the last 4-5 years! Information redacted pursuant to the freedom of information act (foia), 5 u.S.C. 552(B)(6). *Tr
2007 Rx350. Condensation in passenger side headlight. They issued a "warranty enhancement" to avoid a class action lawsuit. That program has expired and they tell you, "oh well, pay us 2100.00 If you want headlights that work"
Abs brake light, traccin light, no power brake, my caro has 90,996 miles
Condensation buildup in headlight assembly constantly.
Headlight lowbeam failure due to excess water condensation inside light assembly. It is a manufacturing defect that lexus has kept secret throughout the years. Instead if issuing an expensive recall on all the years affected, they simply fixed as the cars came in with the problem. They know that it is cheaper for them to do so in that manner because most lexus owners garage their vehicles and wont have the failure untill it is too late. Their program to fix the problem ends within a 10 year period. Can you...

investigate and force lexus to issue a recall on all cars affected regardless age or ownership. My lights failed during the rain at nightwhile going home. It really is a very important safety issue.
Parked, and when I turned on car both highbeams went dim. Went to replace bulbs and the new bulbs are still dim and beginning to bubble. *Tr
Head light gather water which causes dim head lighting . Coiled go out at anytime while driving. Lots of condensation on the hid headlights. *Tr
There was a condensation that formed inside the driver-side headlight. It caused the headlight to short-circuit and blow out. One simply needs to google 'lexus rx headlight' and they will find this to be a common occurrence among 2004-2009 models of lexus rx. Unfortunately, it appears lexus/toyota will not issue a recall for a what is clearly a manufacturer defect, and demanding us to repair the headlight at our own expense, which is substantial. Could the nhtsa investigate these defects? *Tr
The headlight assembly collects moisture on the inside and fails. It is a known problem to lexus/toyota and there have been numerous complaints to dealers on the rx330, rx350 and rx400h models. The same assembly is used from 2003-2009 for the rx models and lexus issued a technical service bulletin in january 2010 ( l-sb-0008-10) to dealers to replace the assembly if owners complained about it while the vehicles were under warranty, but have decided to do nothing about it on mine because it is out of warranty. The...

lexus customer complaint representative who addressed my claim also advised me that customer loyalty is one of the factors they used to determine whether or not the company will pay for the replacement. Driver saftey should be the concern. *Tr

year. The lexus customer complaint representative who addressed my claim also advised me that customer loyalty is one of the factors they used to determine whether or not the company will pay for the replacement. It is my first lexus vehicle and it doesn't make sense to me. Cost of replacement is $1560.00. *Tr
Headlamp condensation make light on off. It is safety concern. *Tr
Driver side headlamp develops condensation and causes headlamp bulb to burn out. Common problem apparently with rx 330s/350s & 400h. Lexus will not fix if it is out of warranty. *Tr
Lexus rx 330 headlight assembly is defective. Everytime I wash my rx330 or if it rains, water leak in the headlight assembly creates moisture inside the headlights. This causes less visibility at nights and is a safety issue. There are several hundred complaints for the same issue on the web; however, lexus/toyota will not recall their defective headlight assembly. They are even reluctant to acknowledge that this is an issue. Will appreciate if nhtsa investigates this issue and take necessary action against lexus asap. *Tr
