“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. …”
NHTSA complaint #10583578, filed 2014-04, 155,000 miles“The instrument cluster in my '93 Lexus LS400 goes dead intermittently. When this happens, every indicator stops working. I believe that this is a safety issue because the speedometer and fuel gauges do not operate. This has caused 2 close calls recently for my wife. She ran out of gas in heavy traffic once. She just got a speeding ticket this week for 45mph in a 35mph zone. Ts”
NHTSA complaint #10002838, filed 2003-01, 93,000 miles“I drove my car to work on thursday. After work while I was driving home, I smelled gas. When I got home the car was smoking underneath the hood. My son almost opened the hood to check the smoke; he burned his finger. A passerby told him not to open it because it was on fire. My son called 911. I don't know how or why the fire started, but it started underneath the hood. I have had this car for 5 years. I have never had any problems. Can you tell me if there are any recalls for the 93 Lexus, ls 400. I noticed a recall for the 95, where a fire can start underneath the hood. Is my year fine. …”
NHTSA complaint #10158431, filed 2006-05, 188,000 miles“To whom it may concern: I have a '93 Lexus LS400. Apparently, 80% of these cars in this year have faulty instument panels. The speedometer and tach needles do not work, gas gauge is hardly responsive, and at night the lights fail to turn on leaving the driver in a dangerous situation. This of course is a safety issue and I believe is a direct result of a factory design flaw, which Lexus should help resolve. The problem has been lingering for over 6 years now because Lexus has quoted me at $1500 to replace the circuit board!!!! How can they get away with this??? …”
NHTSA complaint #10067776, filed 2004-04, 65,000 miles“1993 Lexus ls 400- dash illumination fails, preventing driver from seeing speedometer, tachometer, gas gauge, engine warning lights and gear indicator. This is a very wide spread problem in this vehicle and a recall is required.”
