The U.S. Dept. of Transportation is continuing to review vehicles involved in Toyota Motor Corp.’s recent recalls involving the floor mat and/or accelerator mechanism. Both defects can cause the throttle to remain open in vehicles after the driver has released pressure from the accelerator pedal.
An unnamed DOT official tells Automotive News that the ongoing review includes looking into possible electronic problems that might cause unintended acceleration separate from the floor mat or pedal linkage problems. Toyota has repeatedly said there is no evidence of any electronic malfunction in the vehicles.
Last year’s recall was to fix floor mats that could catch on the accelerator pedal. Toyota is installing new mats and in some cases installing a brake override system and/or modifying the floor pan. This year’s recall is to remedy a design flaw that could allow condensation to prevent or slow the accelerator pedal’s return to the idle position. Toyota says its dealers will install a spacer bar to help maintain clearance so the pedal’s return spring operates normally.
Some consumer groups contend that electronic problems are causing or at least contributing to acceleration problems in Toyota vehicles. Toyota, Consumer Reports and the National Highway Traffic Safety Administration say they have been unable so far to identify such a flaw.
Congressional hearings on the Toyota recalls begin next week and are expected to focus on complaints that Toyota and NHTSA were slow to respond to complaints about the acceleration problems.
