2003 Lexus RX300 Problems

Owner-reported complaints filed with NHTSA, grouped by component

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Everything below is an owner-reported complaint submitted to NHTSA about the 2003 Lexus RX300, grouped by the component NHTSA recorded on the report.

reports

From owner reports, verbatim

DURING NORMAL DRIVING, WITH NO SIGNS OF FAILURE, THE VEHICLE SUDDENLY WOULD LOSE POWER WHEN PRESSED ON GAS, IT ACTED AS IF IT WERE IN NEUTRAL---ENGINE REVS UP, BUT CAR DOES NOT MOVE. THEN WHEN SWITCHED TO SECOND GEAR OR L, TRANSMISSION STILL WOULD NOT ENGAGE. HAD IT TOWED TO A LOCAL TRANSMISSION SHOP, IT TURNED OUT TO BE THE PLANETARY GEAR BROKE. SEARCHED ONLINE LEXUS FORUM, FOUND OUT VERY MANY PEOPLE REPORTED THE SAME FAILURE IN TRANSMISSION. *TR

NHTSA ID 10402143 · filed May 20, 2011

THE TRANSMISSIONS IN LEXUS RX300 MODELS ARE UNSAFE. THE TRANSMISSION IN MY RX300 HAD TO BE REPLACED AT 70,000 MILES AND AGAIN AT 120,000 MILES. LEXUS IS NOT STANDING BEHIND THEIR PRODUCT. THERE HAVE BEEN NUMEROUS COMPLAINTS ABOUT THE TRANSMISSION IN THE RX300 MODEL. LEXUS WILL NOT ACKNOWLEDGE THIS DEFECT. ALSO, I WAS MISLED AT THE DEALERSHIP THE FIRST TIME THEY REPLACED THE TRANSMISSION. I WAS ASSURED THAT THE TRANSMISSION WAS NOT "REFURBISHED", WHEN, INDEED, IT IS NOT A NEW TRANSMISSION. THE DEFINITION OF THE WORD "REFURBISHED" WAS IN QUESTION. THE TRANSMISSION GOING OUT REPEATEDLY AND SO EARLY IN THE RX300 MODEL IS A SAFETY HAZARD. LEXUS' FAILURE TO ACKNOWLEDGE THE PROBLEM AND THEIR DECISION TO WAIT UNTIL SOMEONE HAS A PROBLEM WITH THE TRANSMISSION IS A SAFETY ISSUE IN ITSELF. *TR

I CALLED MY LOCAL LEXUS THREE TIMES PRIOR TO JUNE, 2012 REGARDING LIGHTS SUDDENLY ILLUMINATING ON THE DASHBOARD. I HAD A RECURRING ISSUE WHERE THE CHECK ENGINE AND VSC WARNING LIGHTS WOULD ILLUMINATE. EACH TIME THE CUSTOMER SERVICE AGENT TOLD ME THAT THE LIGHTS WOULD GO OFF WHEN I REFUELED. THREE TIMES THE LIGHTS DID GO OFF (AFTER SEVERAL DAYS), BUT ONCE I HAD TO HAVE THE DEALER RESET THEM. THE MOST RECENT OCCURRENCE RESULTED IN THE DEALER TELLING ME I NEEDED THE AIR FUEL AND AIR FLOW SENSORS REPLACED, A REPAIR WHICH COST OVER $750.00. AS AN ASIDE, EVERY TIME I CALLED TO INQUIRE ABOUT THE LIGHTS BEING ILLUMINATED MY CAR WAS UNDER WARRANTY AND NO REPAIRS WERE SUGGESTED. AFTER THE WARRANTY EXPIRED I WAS THEN ADVISED THAT THE SENSORS NEEDED TO BE REPLACED. *TR

NOT MY VEHICLE, BUT ON OTHER VEHICLE ON THE ROAD. NUMEROUS TIME I HAVE HAPPENED UPON A NEWER LEXUS RX 300 (2002 OR 2003 MODEL??) WITH NO TAIL LIGHTS, TRAVELING ALONG PUBLIC ROADWAYS WELL AFTER DARK. IN A RECENT INCIDENT, I WAS ON A MULTI-LANE FREEWAY AND HAD A CHANCE TO PULL ALONG SIDE A LEXUS RX 300 WITH NO TAIL LIGHTS, GLANCING OVER AT THE DRIVER COMPARTMENT OF THE RX 300, I NOTED THAT THE DASH/INSTRUMENT LIGHTS WERE ON! AND, THE DAYTIME RUNNING LIGHTS (DLRS) WERE PROVIDING SOME FORWARD ILLUMINATION FOR THE VEHICLE. I LATER DISCOVERED THAT THE RX 300 VEHICLES ALWAYS HAVE THEIR INSTRUMENT PANEL ILLUMINATED, THUS WITH THE COMBINATION OF THE DLRS, IT SEEMS THAT THE DRIVERS OF LEXUS RX300 SUV'S FREQUENTLY FORGET TO TURN THEIR HEADLIGHTS ON. THERE IS AN "AUTO" FEATURE, BUT IF NOT USED, THE VEHICLE IS VERY PRONE LEAVING THE DRIVER WITH A FALSE SENSE THAT THE LIGHTS ARE TURNED ON- WHICH IS VERY DANGEROUS. I CAN NOT THINK OF ANY OTHER VEHICLE THAT ILLUMINATES THE DASH WITHOUT AT LEAST TURNING ON THE TAIL/PARKING LAMPS. I FEEL THIS IS A DEFECT IN THIS VEHICLE DESIGN THAT COULD NEEDLESSLY LEAD TO ACCIDENTS. *NLM

THE VEHICLE SUDDENLY LOST TRANSMISSION ON THE ROAD AND WAS ROLLING FREELY. THE GEARS DOES NOT WORK ANYMORE AND THE VEHICLE ROLLS AS IF ITS IN NEUTRAL. WHEN SEARCH THE INTERNET I LOOKED AT LOT OF THE CUSTOMERS COMPLAINING ABOUT EXACT SAME THING, ABOUT THIS VEHICLE HAVING TRANSMISSION ISSUES ESPECIALLY FOR RX300. NO WONDER TOYOTA HAS THIS MANY RECALLS AND SURPRISED THAT THEIR PREMIUM BRAND HAS THE SAME ISSUES WITH SAFETY. I AM GLAD THAT THIS DID NOT HAPPEN ON A HIGHWAY
