RX300 ABS Brake Problems
How many failures does the government need to see to realize a rusted part on an axle that defeats the ABS brakes is a defect. Especially if the fix requires a replacement of the axle.
We have had two fail in the past year on our 2000. Northern climate.

Welcome to CL as a new poster. 
Moderators...can we discuss this issue here, or do you want to move it to the Maintenance or RX forum?
Back to the original question....if a metallic part corrodes after almost 15 years, that might not be considered a defect, even with a brake function. Vehicles aren't expected to last forever, especially in damp, salt/rust-prone conditions.

what are you talking about? the area where the abs sensor slips into on the knuckle? Yes it is a problematic area for rust since the knuckles are cast iron as is on most cars. A quick blast of brake cleaner will usually dislodge metal filings that would stick to the sensor that effect the sensitivity.
ABS receives its signal from the tone ring on the axle. Unless that ring is damaged, there is no other reason to replace the axle than a ripped boot.

Any part that is not designed for the reasonable life of a car in normal conditions that affects safety is a problem. We expect air bags to function, steering wheels to stay on, and ABS systems to function. They are not on the maintenance list as brake shoes and calipers are. If the part spins on the axle and the dealer states they can not legally weld it back on, it is a regulated safety item. At over $700 per time, I question the material used in design. Talking to the dealer and independent repair locations, it is a common problem of the RX300 design.
Does this mean I should consider not giving my 2008 or 2013 to my family as safety items are not expected to last? That was why this brand was purchased originally.
