Since about a year after the car was new, a foul odor appears when the heater comes on. Tried changing Cabin Filters, spraying a lemon deodorizer into vents, dealer has did there fresh air treatment a # of times, I dusted the cabin filters with baking soda, I tried putting the heater on high-run the car with windows closed for an hour or two, but all has failed.

I can't barely hear my callers and/or the instruction on the navigation system from the speaker on the driver's door. Callers hear me...I can't hear them.

The battery seems to be OK. Is there an auto shut down feature, anti theft or other system that is doing this? I bought it in April 2014 so this is new to me. Any advice?

I never heard of it. But other then that the car is fine.

Looking at two Lexus LS 430s both are now 12+ years old, both under 45,000 miles. Neither has had timing belt changed.
Opinion/Experience: Does the belt need to be changed due to age and possible hardening of rubber, etc.?
Thanks! -- Rick

When adjusting level of A/C flow, touch screen buttons will not always change when touched. Also, adjust clock is problem. Is not recognizing touch.
This has just started. Will it quit completely? Is it expensive to replace. A GPS is also in display, but rarely used.

I have a 2002 LS430 with Mark Levenson system. The radio works but only with on screen touch. The volume and station controls knobs do not work.

Just purchased vehicle with only 49k miles. Left rear speaker buzzess/vibtaes with any bass volume. Would love to upgrade NAV & stereo and rear speakers to a new audio system that can access Pandora through an app or bluetooth streaming from my iPhone5. Can anybody recommend one that can be retrofitted to the 2004 LS430 center stack, already configured with Mark Levinson audio? One that will look nice & custom? Also need to replace the pneumatic struts for trunk lid (trunk won't pop open and stay up on its own) and want a cost effective source/solution.

2001 Lexus Ls 430 ( I have turned the volume down before and now I forgot how to do it again) . Recently changed battery out.
