MY 2006 SUBARU LEGACY WAGON SUDDENLY LOSES ACCELERATION SOMETIMES, CHECK ENGINE LIGHT COMES ON, CRUISE CONTROL FLASHES, AND THE GAS PEDAL DOES NOTHING. THE CAR THROWS A P2138 CODE "THROTTLE/PEDAL POSITION SENSOR" CODE WHEN CHECKED. THIS HAS HAPPENED ABOUT 10 TIMES OVER THE LAST YEAR. IF YOU RESTART THE CAR, IT SOME TIMES GOES AWAY, MOST TIMES IT REQUIRES SEVERAL RESTARTS AND TIME. THE CAR WILL DO THIS WHEN MOVING FAST ON THE HIGHWAY OR JUST SITTING. THE GAS GOES LIMP AND THERE IS NO REVVING OR ACCELERATION. THIS IS A DANGEROUS PROBLEM AND APPARENTLY DISCUSSED ON MANY FORUMS, ALL INVOLVING SUBARU'S FROM THE SAME ERA. *TR

WHILE TRAVELING AT APPROXIMATELY 55MPH, MY LEGACY'S THROTTLE BECAME UNRESPONSIVE, THE CHECK ENGINE LIGHT CAME ON, AND THE CRUISE LIGHT BEGAN TO FLASH. I WAS ABLE TO SAFELY COAST OFF THE ROAD AND A SUBSEQUENT CODE CHECK REVEALED A CODE 2138 (THROTTLE POSITION SENSOR). IN THE ENSUING MONTHS I REPLACED THE TPS, WHICH DIDN'T HELP, THEN RESEATED THE CONNECTION ON THE THROTTLE ITSELF, WHICH WORKED FOR ABOUT SIX MONTHS. THE PROBLEM HAS RECENTLY RECURRED AND SEEMS TO BE A COMMON PROBLEM. *TR

2006 SUBARU LEGACY, BOUGHT NEW, IT HAS EXPERIENCED A STUTTER SINCE NEW. THE STUTTER OR LACK OF HESITATION OCCURS EVERY TIME I STEP ON THE GAS PEDAL. IT CAUSES ME TO HESITATE AT TRAFFIC LIGHTS AND EVERYWHERE ELSE AS I KNOW THE CAR WILL NOT RESPOND PROPERLY. I MISSED THE LEMON LAW POTENTIAL OF THIS ISSUE BECAUSE I WAS GOING THROUGH A DIVORCE, CHANGING JOBS AND MOVING. THE BIGGEST REASON I MISSED THE LEMON LAW RECOVERY IS I KEPT BELIEVING THE DEALERS COMMENTS THAT IT WOULD BE FIXED AT THE MAJOR TUNE UP. I CONSISTENTLY REPORTED TO THE DEALER AT EVERY SERVICE VISIT THAT THE CAR STILL HESITATES TO NO AVAIL. I HAVE FOUND ONLY LIMITED INFORMATION SEARCHING THE INTERNET FOR OTHERS WITH THE SAME PROBLEM. I BELIEVE THIS QUALIFIES AS A SAFETY ISSUE BECAUSE I CANNOT DRIVE DEFENSIVELY, IF I WAS REQUIRED TO HESITATE QUICKLY TO AVOID AN ACCIDENT I WOULD NOT BE ABLE TO DO SO. THANK YOU! *TR

ABOUT A MONTH AGO I PURCHASED A 2006 SUBARU LEGACY 2.5 GT MT. I HAVE TWO MAJOR COMPLAINTS THAT MOST PEOPLE COMPLAIN ABOUT. 1) HESITATION UNDER ACCELERATION. THIS PROBLEM IS KNOWN BY SUBARU. ONE TECH TOLD ME THAT THE ECU NEEDS TO BE REFLASHED, BUT THAT SUBARU HAS NOT COME UP WITH A FLASH TO FIX THE PROBLEM YET. 2) BAD SMELL FROM THE CLUTCH. HAPPENS MOSTLY IN STOP AND GO TRAFFIC, BUT OCCURS AT OTHER TIMES TOO. I'VE HAD IT HAPPENED WHEN I FIRST START THE CAR, AFTER DRIVING IT FOR A LONG TIME, CRUISING ON THE HIGHWAY AND SHIFTING. IT IS VERY BOTHERSOME.*JB

Remedy: Subaru will notify their owners. General Motors will notify Saab owners. Dealers will replace the passenger air bag inflators with alternate inflators, free of charge.

Consequence & remedy
Consequence: The engine turning off unexpectedly can increase the risk of a crash. If a crash occurs under this condition, the air bag may not deploy, increasing the risk of injury.
Remedy: Subaru will notify owners, and dealers will inspect the ignition switch, replacing the ignition switch, if necessary, free of charge. The recall began May 10, 2019. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WUF-91.

The affected vehicles are equipped with a passenger side frontal air bag that may be susceptible to moisture intrusion which, over time, could cause the inflator to rupture upon its deployment.
Consequence & remedy
Consequence: In the event of a crash necessitating deployment of the passenger's frontal air bag, the inflator could rupture with metal fragments striking the vehicle occupants potentially resulting in serious injury or death.
Remedy: Subaru will notify their owners and General Motors will notify Saab owners. Dealers will replace the passenger air bag inflator, free of charge. The Subaru recall began on June 17, 2015. Owners may contact Subaru customer service at 1-800-782-2783. The Saab recall began on July 27, 2015. Owners of Saab vehicles may call 1-800-955-9007. Subaru's number for this recall is WQR-53. Note: The recall completely supersedes recall 14V-399 (WQL-48) and partially supersedes recall 14V-763 (WQP-51) in that model year 2004 through 2005 Subaru Impreza and model year 2005 Saab 9-2x vehicles are now only part of this campaign. Note: On December 18, 2015 Subaru informed NHTSA of an expansion of this recall to include certain model year 2003-2004 Subaru Baja, 2003-2008 Subaru Legacy and 2003-2008 Subaru Outback vehicles.

Jun 10, 2014
Subaru of America, Inc. (Subaru) is recalling certain model year 2005-2009 Outback and Legacy, 2008-2011 Impreza and 2008-2014 Impreza WRX/STI, and 2009-2013 Forester vehicles, currently, or formerly, registered in Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin and the District of Columbia. Salt water could splash on the brake lines through a gap in the fuel tank protector, resulting in excessive corrosion of the brake lines. Note that affected vehicles not currently, or formerly registered, in the salt belt states identified above are eligible for repair, at no cost to the customer, upon request.
Consequence & remedy
Consequence: Brake line corrosion may result in brake fluid leakage. Fluid leakage may result in longer distances being required to slow or stop the vehicle, increasing the risk of a crash.
Remedy: Subaru will notify owners, and dealers will test the brake system by depressing the brake pedal and inspecting for brake fluid leaks. If no brake fluid seepage is observed, the affected areas will be rustproofed with anti-corrosion wax. If brake fluid seepage is observed, the brake lines will be replaced followed by rustproofing with anti-corrosion wax. These services will be performed free of charge. The recall began July 2014 and second notifications will run through November 2014. Owners may contact Subaru at 1-800-782-2783. Subaru's recall campaign number is WQK-47. Note: This recall supersedes recall 13V-110 which applied to certain 2005-2009 Legacy/Outback vehicles. Vehicles that were remedied under the previous campaign still need additional areas rust-proofed.
