1993 Lexus LS400

RECENTLY THE CAR BEGAN TO STUMBLE UNDER ACCELERATION WHILE DRIVING UP A HILL OR MERGING INTO TRAFFIC OR MAINTAINING SPEED WHILE DRIVING ON THE INTERSTATE. I INITIALLY THOUGHT IT WAS A FUEL SUPPLY ISSUE SO I CHANGED OUT THE FUEL FILTER, WITHOUT ANY IMPROVEMENT IN THE PROBLEM. I WAS GOING TO CHANGE THE FUEL PUMP ALSO AND WHILE RESEARCHING ON THE INTERNET I LEARNED OF A PROBLEM WITH BAD ELECTROLYTIC CAPACITORS INSIDE THE CAR'S ECU (ENGINE COMPUTER) WHICH CAN MIMIC A FUEL SUPPLY PROBLEM. I AM A TRAINED ELECTRONICS TECHNICIAN, SO I REMOVED AND DISASSEMBLED THE VEHICLE'S ECU AND REPLACED 2 CAPACITORS (COST, LESS THAN $1) THAT I COULD SEE WERE BAD (LEAKING ELECTROLYTE FLUID). I TEST DROVE THE CAR AND THE "FUEL SUPPLY PROBLEM" WAS GONE, IT DROVE NORMALLY AGAIN AND DID NOT STUMBLE WHEN THE ACCELERATOR PEDAL WAS PRESSED. I ORDERED THE OTHER 5 OR 6 ELECTROLYTIC CAPACITORS IN THE ECU (FROM AN OUTSIDE SOURCE, THE DEALER WILL ONLY SELL A COMPLETE ECU FOR $2000 PLUS) TO HOPEFULLY PREVENT FUTURE OCCURRENCES. IN CONCLUSION, IT APPEARS THE BAD CAPACITORS ARE THE RESULT OF A "LARGE-SCALE INDUSTRIAL ESPIONAGE FOUL-UP". NOT A JOKE! THIS RESULTED IN DEFECTIVE CAPACITORS BEING USED IN MANY ELECTRONIC ASSEMBLIES (CONSUMER ELECTRONICS, AUTOMOTIVE, HOUSEHOLD, ETC.) UNTIL THE ISSUE WAS DISCOVERED, SEE WWW.BADCAPS.NET FOR THE STORY. I FORGET WHERE I LEARNED OF THE CAPACITOR PROBLEM ON THE LS400, BUT IT WAS JUST BY SEARCHING ONLINE. SO BASICALLY, LEXUS IS CHARGING CUSTOMERS OVER $2000 TO REPAIR A SAFETY ISSUE (THAT IS CAUSED BY LESS THAN $5 WORTH OF PARTS (RETAIL COST) AND A LITTLE SOLDERING SKILLS/LABOR) THAT WAS THE RESULT OF IMPROPERLY DESIGNED/MANUFACTURED ELECTRONIC COMPONENTS FROM THEIR SUPPLIER. *TR

I HAVE A 93 LEXUS LS400 WITH 76,000 MILES. THE WHITE LED SPEEDOMETER POINTER HAS BURNED OUT. THE HENDRICK LEXUS SERVICE DEPARTMENT SAID I WOULD NEED A NEW SPEEDOMETER CLUSTER COSTING OVER $200 PLUS ABOUT $160 IN LABOR. THIS SEEMS TERRIBLY WRONG TO ME. WITH THE SPEEDOMETER POINTER BURNED OUT, IT IS IMPOSSIBLE TO DETERMINE THE SPEED OF THE VEHICLE WHEN DRIVING AT NIGHT. IT IS LIKEWISE VERY DIFFICULT TO TELL HOW FAST YOU ARE DRIVING DURING THE DAY. *AK
