I OWN A 2007 LEXUS RX350. WHEN STARTING MY CAR, A GRINDING SOUND IS HEARD COMING FROM THE ENGINE EVERY 1 OUT OF 7 OR 8 TIMES. THE PERFORMED A DIAGNOSTIC TEST, AND THE DEALER ADVISED THAT THE CAMSHAFT TOWER WOULD NEED REPLACING. APPARENTLY THIS IS A COMMON PROBLEM WITH THE YEAR, MAKE, AND MODEL. THE FAILURE MILEAGE WAS 89,000. LEXUS SAID THEY WOULC COVER PARTS BUT NOT LABOR, LABOR IS 2/3 OF THE COST (TOTAL ESTIMATE $3800). APPARENTLY THE CAR IS UNSAFE TO DRIVE AS IS. *TR

I HAVE NOW HAD TO REPLACE 3 IGNITION COILS. I ONLY HAVE THE PAPERWORK FOR 2 TIMES, BUT EACH TIME THE CAR BEGAN TO RUN ROUGH AND THE ENGINE WENT OFF AT STOPS, AND THE ELECTRICAL SYSTEM LIGHT WENT ON. THE FIRST TIME THIS HAPPENED, WHICH I THINK WAS IN 2010, THE LEXUS TECHNICIAN SAID IT WAS A FLUKE. THE SECOND TIME (ABOVE DATE), THE LEXUS TECHNICIAN SAID HE WAS BEGINNING TO SEE A LOT OF IGNITION COIL FAILURES. THIS LAST TIME (TODAY), THE TECHNICIAN SAID REPLACING FAULTY IGNITION COILS IS NOW COMMON, AND JUST A PART OF MAINTENANCE. HE ALSO SAID SOME PEOPLE WERE CHOOSING TO REPLACE ALL 6 OF THEM AT ONCE SO THAT THEY WOULDN'T BE STRANDED AT NIGHT OR ON THE ROAD, AND TO SAVE MONEY. OBVIOUSLY, THERE'S A MAJOR PROBLEM WITH LEXUS RX350 IGNITION COILS. *TT

Official recalls

11V112000 · Vehicle Speed Control:accelerator Pedal

Feb 24, 2011

TOYOTA IS RECALLING CERTAIN MODEL YEAR 2004-2006 HIGHLANDER, HIGHLANDER HYBRID, AND MODEL YEAR 2004-2007 LEXUS RX330, RX350, AND RX400H VEHICLES. IF THE FORWARD RETENTION CLIP USED TO SECURE THE FLOOR CARPET COVER, WHICH IS LOCATED IN FRONT OF THE CENTER CONSOLE, IS NOT INSTALLED PROPERLY THE COVER MAY LEAN TOWARD THE ACCELERATOR PEDAL AND INTERFERE WITH THE ACCELERATOR PEDAL ARM.

Consequence & remedy

Consequence: IF THIS OCCURS, THE ACCELERATOR PEDAL MAY TEMPORARILY BECOME STUCK IN A PARTIALLY DEPRESSED POSITION RATHER THAN RETURN TO THE IDLE POSITION. A STUCK ACCELERATOR PEDAL MAY RESULT IN UNINTENDED AND SUSTAINED VEHICLE SPEEDS AND MAKE IT DIFFICULT TO STOP, INCREASING THE RISK OF A VEHICLE CRASH.

Remedy: DEALERS WILL REPLACE THE FLOOR CARPET COVER WITH A NEWLY DESIGNED ONE FREE OR CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN DURING MARCH 2011. OWNERS MAY CONTACT TOYOTA AT 1-800-331-4331.

NHTSA investigations

RQ10003 · Unintended And Uncontrolled Acceleration

Opened Feb 16, 2010 · Closed Mar 1, 2011

Status: closed (inferred from source dates) · Electrical System:software; Vehicle Speed Control:accelerator Pedal

On February 16, 2010, NHTSA's Office of Defects Investigation (ODI) opened RQ10-003 to determine whether the scope of prior Toyota recalls relating to potential unintended acceleration were sufficiently broad, including, among others, Toyota recalls 07E-082, 09V-388, 10V-017, and 10V-023.NHTSA also requested information regarding potential electronic causes of unintended acceleration in Toyota and Lexus vehicles.I. Pedal Interference from Floor mats, Carpet Covers and Plastic Pads in Carpets.During the RQ10-003 investigation, ODI reviewed a large volume of documents to assess whether additional vehicles should be recalled.Following the agency's analysis, NHTSA requested that Toyota recall additional vehicles.Toyota complied with the agency's request.The details of these recalls are set forth more fully in Toyota's reports to NHTSA pursuant to 49 CFR Part 573.These recalls are as follows:Recall 11V-112: (1) model year (MY) 2004-2006 Toyota Highlander and Highlander Hybrid; and, (2) MY 2004-2007 Lexus RX330,RX350, and RX400h (hybrid model). The total estimated population under this recall is 769,379 vehicles.This recall remedies potential accelerator pedal entrapment caused by a loose floor carpet cover (trim panel). Recall 11V-113: (1) MY 2003-2009 through 2009 Toyota 4Runner; (2) MY 2006-2010 Toyota RAV4; and, (3) MY 2008-2011 Lexus LX570.The total estimated population under this recall is 1,381,000 vehicles.This recall supplements recall 09V-388 and remedies potential accelerator pedal entrapment by an unsecured floor mat.Recall 11V-115: (1) MY 2006-2007 Lexus GS300 (all wheel drive vehicles); and, (2) MY 2006-2007 Lexus GS350 (all wheel drive vehicles). The total estimated population under this recall is 19,647 vehicles.This recall remedies potential accelerator pedal entrapment caused by inadequate clearance between the pedal linkage and a plastic pad embedded in the vehicle's carpet.II. Potential Electronic Causes of Unintended Acceleration.After NHTSA opened RQ10-003, NHTSA launched a ten-month study of potential electronic causes of unintended acceleration in Toyota vehicles.NHTSA launched the study in the spring of 2010 in light of concerns aired in Congressional hearings.NHTSA enlisted engineers at the National Aeronautics and Space Administration (NASA) with expertise in areas such as computer controlled electronic systems, electromagnetic interference and software integrity to assess whether electronic systems or electromagnetic interference played a role in incidents of unintended acceleration in Toyota vehicles.That study has concluded.Two reports are associated with the study and are available on NHTSA's website.NASA's report is entitled Technical Support to the National Highway Traffic Safety Administration (NHTSA) on the Reported Toyota Motor Corporation (TMC) Unintended Acceleration (UA) Investigation, NESC Assessment No. TI-10-00618 (Jan. 18, 2011).NHTSA's report is entitled Technical Assessment of Toyota Electronic Throttle Control (ETC) Systems (Feb. 2011).Both reports should be read in conjunction with each other. As stated in its report, NASA did not find an electronic cause of large throttle openings that can result in unintended acceleration incidents. NHTSA did not find a vehicle-based cause of unintended acceleration incidents other than the physical pedal interference causes that are being addressed by Toyota's recalls. This RQ is closed.
