The Lexus RX 300 is one of the very first crossovers in the market. The RX 300 is a trailblazer to an extent, as its success pushed rival makes to launch their very own crossovers. While it's recognized as one of the best luxury SUVs in the market for its reliability and consistent performance, the RX 300 wasn't without problems. Below were some of its most common ills.
Some Lexus RX 300 owners reported automatic transmission fluid leaks within the transmission system. Also, transmission failures were somewhat a common occurrence. What's worse is when that happens, the torque converter will stop working as well.
Since fuel efficiency is a big thing for most automotive owners, the Lexus RX 300's rather poor mileage didn't sit well with some owners. The RX 300 rated at around 17 mpg. Its considerable weight (which was almost 2 tons) significantly affected the RX 300 in this category.
The headlights and taillights often bugged Lexus RX 300 owners. When the headlight switch was set to
AUTO, both the headlight and the taillight wouldn't always illuminate automatically when subjected in conditions where there's low ambient light. This led to momentary (at least until drivers manually switch on the headlights and the taillights) road vision impairment.
The Lexus RX 300's rear-view mirror and side-view mirrors did not meet the federal motor vehicle safety standards. And because of that, they tend to create excessive glare for drivers, thus impairing road vision when driving at night. Needless to say, this issue could be particularly dangerous.
The Lexus RX 300 occasionally made unnecessary and annoying noises. Suspension noise, squealing brakes, and rackety sounds from the moon roof (which was a result of the awkward placement of the luggage rack's cross bars) often plagued the RX 300. The last one can be easily solved by modifying the cross bars though.
Although this is a very minor issue, many owners didn't appreciate the unnecessarily large temperature and trip display in the Lexus RX 300's center console. They found it distracting and a waste of space.
