What owners say about the electrical system

Verbatim from NHTSA complaints, newest first
“Four Subaru dealership licensed service centers in Maine and New Hampshire have had for some 8 weeks my Outback to evaluate, diagnose, and -upon my approval- service. Every one of the four Subaru locations was been unable to resolve a single one of these chronic problems of the Outback's erratic 1) start/no-start, 2) triggered security light and activated alarm, 3) dashboard battery and brake icons lighting/pulsing, 4) error code 55 (or SS) and 5) car headlights pulsing. The above problems compound with the issues Subaru's service teams have failed to resolve since early days of new car ownership (despite repeated repair) for 1) brakes regularly making noise, 2) radio randomly changing volume or shutting off, and 3) back tail light not working. Note: During the first two years of ownership, Subaru's service stated it "could not replicate" the problem with the brakes I'd reported within weeks of purchasing the new car. But a few weeks out of warranty, the same Subaru service location stated "I need whole new brakes" and quoted some $1,800 in repairs. A few months later, Subaru issued its first admission to the defective brake system. These four Subaru dealership…”

“The contact owns a 2008 Subaru Outback. The contact stated while driving at an undisclosed speed and attempting to depress the brake pedal, the brakes failed to function. The contact took the vehicle to the dealer who diagnosed the failure and replaced the brakes. The contact stated that while attempting to start the vehicle, the vehicle would not start. The contact had the vehicle towed to a dealer and the battery was replaced. Soon after the battery replacement, the front headlights began strobing and the taillight wiring caused the lights to fail. Additionally, there was moisture behind the A-pillar applique trim. The vehicle was taken to a dealer, and the contact was informed that the alternator needed to be replaced. Additionally, the wiring and bulbs in the taillights needed to be replaced. The manufacturer was made aware of the failure and advised the contact to reach out to the NHTSA Hotline for assistance. The vehicle was not repaired. The failure mileage was approximately 100,000.”

“EVER SINCE I PURCHASED MY CAR FROM CARMAX THERE HAVE BEEN PROBLEMS WITH THE IGNITION SWITCH. THERE HAVE BEEN ABOUT 10+ TIMES SINCE I PURCHASED THE VEHICLE IN DEC. 2016 THAT I WILL PUT THE KEY IN THE IGNITION, (WHILE THE CAR IS PARKED AND TURNED OFF, IN ORDER TO TURN IT ON) AND THE ENGINE WON'T TURN OVER. I HAVE TO TOGGLE THE GEAR SHIFTER IN ORDER TO GET THE CAR TO RESPOND AND THEN THE CAR WILL TURN ON. (ONLY AFTER I AGITATE THE GEAR SHIFTER WILL THE IGNITION THEN RESPOND). I RECEIVED AN EMAIL THAT THERE MAY BE A RECALL FOR SUBARU OUTBACK 2008 FOR IGNITION-RELATED ISSUES BUT WHEN I LOOKED UP MY SPECIFIC VIN NUMBER, MY VEHICLE DOES NOT APPEAR TO BE A PART OF THE THE RECALL. PLEASE LET ME KNOW HOW I CAN HAVE MY CAR BE CONSIDERED IN THIS RECALL, I KNOW THIS IS A RELATED PROBLEM.”

“MY VEHICLE HAS A PROBLEM WITH AN INTERMITTENT AIRBAG LIGHT ILLUMINATING, INDICATING AN ISSUE WITH THE AIRBAG SYSTEM. SPECIFICALLY IN MY CASE, IT INDICATES THAT THE OVERHEAD AIRBAG INDICATOR SYSTEM IS IN A FAULT STATE. THIS IS EXTREMELY COMMON IN THIS VEHICLE AND AGE, WITH MANY OTHER OWNERS REPORTING THE SAME ISSUE WITH NO RECALL ACTION FROM SUBARU. THIS IS A MAJOR SAFETY ISSUE WITH THIS CAR IF NOT ADDRESSED AND CAN RESULT IN THE AIRBAGS NOT DEPLOYING IN THE EVENT OF A CRASH. COST FOR AN OWNER TO REPAIR (AND IN MY CASE) IS $300+ AND SHOULD BE COVERED BY SUBARU.”

“THERE'S SEEMS TO BE A COMMON ISSUE WITH THE WIRING ON 2005-2009 SUBARU OUTBACK/LEGACY MODELS THAT AFFECTS BOTH THE AIRBAG AND THE LOCKING MECHANISM. I HAVE SEEN MULTIPLE THREADS ONLINE WHERE THE AIRBAG INDICATOR LIGHT COMES ON SPECIFICALLY INDICATING THAT THE PASSENGER AIRBAG MAY BE AFFECTED AND SENSORS MAY BE FAULTY? THERE IS ALSO A COMMON ERROR IN THE ELECTRICAL SYSTEM IN WHICH WHEN YOU LOCK THE CAR - ALL LOCKS ACTIVATE WITH THE EXCEPTION OF THE REAR TAILGATE WHICH POSES A SAFETY RISK OR TOTAL THEFT OF THE CAR. THESE PROBLEMS OCCUR UPON VEHICLE IGNITION AND WHEN THE CAR IS ON OR OFF (FOR THE LOCKING)”
