PURCHASED A NEW SUBARU LEGACY FEB. 28, 2018. AFTER ONLY 70 MILES THE WARNING LIGHT FOR SEAT BELTS AND AIRBAG MALFUNCTION APPEARED ON A STARLINK SYSTEM AND DASH. AFTER IMMEDIATELY TAKING IT IN AT THE LOCAL CAR DEALER, SERVICE AGENTS CLAIMED THAT A "RODENT" HAS CAUSED THE DAMAGE. AFTER FURTHER RESEARCH, WE HAVE DISCOVERED A NATIONAL CIVIL SUIT AGAINST SUBARU. APPARENTLY THEY ARE USING BIODEGRADABLE MATERIALS ON THE WIRING OF MANY NEW CARS THAT ATTRACTS SQUIRRELS AND MICE. WE HAVE LIVED AT OUR CURRENT RESIDENCE FOR OVER 35 YEARS WITH NUMEROUS CARS IN THE DRIVEWAY WITHOUT THIS PROBLEM. CONSUMER REPORTS ON JULY 10,2017, REPORTED THAT THEY HAVE UNCOVERED VARIOUS TECHNICAL BULLETINS FROM FORD, GM, HONDA, TOYOTA, AS WELL AS SUBARU CONCERNING THIS ISSUE. DEALER, AT THE MOMENT, REFUSES TO FIX IT WITHOUT EXTENSIVE COST TO US. THIS IS A SERIOUS PROBLEM WITH THIS CAR--DRIVING IT WOULD NOT ONLY BE UNSAFE BUT ILLEGAL SINCE THE AIR BAG AS WELL AS THE SEAT BELTS SHOW A MALFUNCTION. FIXING IT MAY NOT SOLVE THE PROBLEM ON PERMANENT BASIS.

CAR WAS PARKED AND LOCKED. KEYLESS ENTRY SYSTEM ALLOWED DOORS TO BE OPENED. UPON SITTING IN DRIVERS SEAT, BEFORE ANY ATTEMPT TO START CAR, A MESSAGE ON DASH SAID "REMOTE KEY DEACTIVATED". AFTER THAT, NOTHING WORKED, NO FURTHER MESSAGES, COULD NOT LOCK DOORS, COULD NOT START CAR, NOTHING FUNCTIONED. FINALLY HAD CAR TOWED TO DEALER, CASEY SUBARU, NEWPORT NEWS, VA. LATE NEXT MORNING, DEALER CALLED TO SAY CAR WAS READY FOR PICKUP. THEY COULD FIND NO PROBLEM, BOTH REMOTE KEYS FUNCTIONED WELL, NO PROBLEM CODES FOUND. CAR OPERATED WELL ON MY DRIVE HOME, <5 MILES. HOWEVER, I HAVE A REAL CONCERN OF GETTING STRANDED IN FUTURE.

THE DRIVERS SIDE MIRROR OF 2018/2019 LEGACY'S WITH BLIND SPOT DETECTION WILL NOT ADJUST OUT FAR ENOUGH TO SEE BLIND SPOT OF VEHICLE FOR SEAT POSITION ADJUSTED FOR AVERAGE TO TALL DRIVERS. WHILE THE MIRROR DETECTION LIGHT WORKS THERE IS NO WAY TO PHYSICALLY CONFIRM SIDE TRAFFIC POSITION. DANGEROUS, ESPECIALLY IN CONGESTED MULTI-LANE ENVIRONMENTS. IT WAS DETERMINED THAT ALL MIRRORS AT A DEALERSHIP WITH BLIND SPOT DECTION HAS THE SAME ISSUE. THIS ISSUE MAY EXIST FOR OTHER YEARS AND MODELS AS WELL. VEHICLES USING MIRRORS WIITHOUT BLIND SPOT DETECTION FUNCTION ADEQUATELY.

THE SUBARU LEGACY WINDSHIELD IS EXTREMELY BRITTLE, SMALL SALT DEBRIS CAUSED THE WINDSHIELD TO HAVE SEVERAL CHIPS ALL OVER THE WINDSHIELD, IN ALL MY YEARS I'VE NEVER SEEN WINDSHIELDS BEING THIS BRITTLE. THERE ARE THOUSANDS OF COMPLAINTS ON SUBARU FORUMS ABOUT WINDSHIELDS THAT HAVE THE EYESIGHT EQUIPPED THAT THEY ARE PRONE TO CRACKING AND CHIPPING EASILY. RECENTLY SUBARU LOST A LAWSUIT ABOUT THEIR WINDSHIELD CRACKING ON THE 2015 AND 2016 SUBARU OUTBACKS, I BELIEVE SUBARU HAS NOT ADDRESSED THIS ISSUE YET. WHILE I WAS DRIVING ON THE HIGHWAY ON MY WAY TO VACAVILLE CALIFORNIA MY WINDSHIELD ENDED UP WITH AT LEAST DOZENS OF CHIPS ALL OVER MY WINDSHIELD. THIS IS UNACCEPTABLE BECAUSE I'VE MADE THIS TRIP COUNTLESS AMOUNT OF TIMES ON MY OLD CAR AND NEVER HAD THIS ISSUE.

ON THE DASHBOARD SHOWED THAT THE REMAIN MILEAGE WAS 70, BUT IT STOPPED ALL THE SUDDEN DUE TO NO GAS. I ALMOST CAUSED AN ACCIDENT BECAUSE THE CAR STOPPED ON A PUBLIC STREET WITH HEAVY TRAFFIC. AFTER MANY TIMES TRYING TO START THE CAR, IT DID NOT WORK; IT WAS COMPLETELY DEAD. I HAD TO LEAVE THE CAR STRANDED TO GO AND GET GAS TO THE NEAREST GAS STATION.

WHILE EXITING OFF HIGHWAY, THE CAN UNEXPECTEDLY SHUT OFF NEARLY CAUSING A WRECK. CAR WOULD NOT RESTART. THE ENTERTAINMENT SCREEN REMAINED WORKING THE ENTIRE TIME. THE INSTRUMENT CLUSTER WENT BLACK AND REMAINED THIS WAY. AUTOMATIC WINDOWS, ENTERTAINMENT SCREEN, RADIO ALL WORKED BUT CAR WOULD NOT START. A SIMILAR ISSUE HAD HAPPENED TWO WEEKS AGO BUT WE WERE NOT DRIVING... THE CAR WOULD NOT START AND A MASTER SUBARU TECH LOOKED AT CAR AND THEY SAID NOTHING WAS WRONG WITH IT.. OBVIOUSLY THEY WERE WRONG. VERY DISAPPOINTED IN SUBARU. THIS IS A VERY DANGEROUS ISSUE.

CAR WAS AT A TURNING INTERSECTION. CAR WAS COMPLETELY STOPPED, FOOT WAS APPLIED TO BRAKE WITH NORMAL PRESSURE. WITHIN A FEW SECONDS, CAR STARTED TO PROGRESS FORWARD, I LIFTED FOOT OFF BRAKE AND REAPPLIED. THE BRAKE DID NOT SENSE PRESSURE, I PUT THE CAR IN PARK. THESE ACTIONS DID NOT STOP THE CAR.

The car (#1) came to a sudden stop on a freeway without the driver stepped on the brake pedal. Front dash cam video on car #1 is available. Car #1 was then hit from behind by another car (#2) which could not stop in time. However, the impact was not significant because car #2 was able to partially switch lane and only the corners of the bumpers of both cars made the contact. The sudden stop problem could NOT be reproduced afterward by the driver. No dealer/car shop has been contacted on this issue. Warning light(s) status on dashboard of car #1 was UNKNOWN . However, driver of car#2 did report seeing brake lights of car #1 before the impact. Car #1 had never been in an accident before. This was the first time the sudden stop issue occurred.

VEHICLE MAKING A LOUD METALLIC RATTLING NOISE WHILE DRIVING BETWEEN 25-45 MPH. SUBARU HAS MADE MULTIPLE ATTEMPTS TO LOCATE AND REMEDY THE NOISE, BUT THEY HAVE NOT SUCCESSFULLY REPAIRED THE VEHICLE AFTER MORE THAN 4 TIMES. CONCERNED THIS COULD BE A POTENTIAL SAFETY ISSUE SINCE THE ISSUE CANNOT BE IDENTIFIED OR REPAIRED.

AT SPEEDS ABOVE APPROXIMATELY 50 MPH, THE STEERING HAS SUDDENLY, ERRATICALLY AND WITHOUT WARNING PULLED THE CAR TO THE LEFT OR RIGHT AS IF HIT BY A LARGE GUST OF WIND (WHEN THERE IS NO WIND OR PASSING TRUCK). IT IS AS IF THE STEERING IS OUT OF CONTROL FOR SEVERAL SECONDS. THE CAR HAS 3,000 MILES AND THIS HAS HAPPENED ABOUT 5-8 TIMES. I NOTICE THERE IS ALSO AN IDENTICAL COMPLAINT FOR 2018 SUBARU OUTBACKS. THIS LAST HAPPENED TODAY. THIS IS A DANGEROUS DEFECT IN THE ELECTRIC POWER STEERING.

VEHICLE SPEED CONTROL

OUR RECENT PURCHASE OF A 2018 SUBARU LEGACY HAS LEFT US WITH A VERY UNHAPPY REALIZATION. WE HAVE A SUBARU OUTBACK AND LIKE THE CAR BUT VERY UNHAPPY WITH THE CRUISE. WE DID NOT REALIZE THE CRUISE CONTROL ADVANCES 1 OR 5 MPH RATHER THAN THE CONVENTIONAL CRUISE OF 1 MPH. WE HAVE FOUND THIS FEATURE TO BE NOT ONLY ON SUBARU BUT MANY OTHER MAKES OF VEHICLES. FROM RESEARCHING ONLINE AND TALKING TO OTHERS HAVE FOUND WE ARE NOT THE ONLY ONES THAT DO NOT LIKE IT AND FEEL IT IS UNSAFE. THERE DOES NOT SEEM TO BE A REASON TO ADVANCE 5 MPH RATHER THAN 1 MPH. WHEN USING THIS TYPE OF CRUISE IT IS NECESSARY TO WATCH THE SPEEDOMETER, RATHER THAN PAYING ATTENTION TO THE ROAD, TO GET TO THE ANTICIPATED SPEED AND THEN QUICKLY SET AND HOPE YOU LOCKED-IN THE DESIRED SPEED. IF THE DESIRED SPEED IS NOT REACHED THE FIRST TIME THEN IT IS PUSHING THE CRUISE AND HOLDING IT, HOPING THAT IT ONLY ADVANCED 1 MPH RATHER THAN 5 MPH, OTHERWISE IT IS CANCELING AND TRYING AGAIN. WE CONTACTED SUBARU ABOUT THIS AND WERE TOLD THAT IF THERE ARE ENOUGH COMPLAINTS THEY WOULD CONSIDER A SOFTWARE UPDATE. IT WAS ALSO EXPLAINED THAT WE WOULD NOT HAVE PURCHASED THE VEHICLE IF WE WERE TOLD THIS BEFORE THE PURCHASE OF THE CAR. WE LOOKED AT THE WEBSITES FOR THE SAFEST VEHICLES AND SUBARU IS AT THE TOP OF THE LIST BUT THIS TYPE OF CRUISE CONTROL TAKES AWAY THE SAFETY; EVERYONE IS PREACHING TO REDUCE DISTRACTIONS WHEN DRIVING BUT TAKING AWAY THE CONVENTIONAL CRUISE CONTROL AND IMPLEMENTING SUCH A DISTRACTION DEFEATS THE PURPOSE. WE HOPE THIS COMPLAINT LEADS BACK TO VEHICLES HAVING CONVENTIONAL CRUISE CONTROL AS THE STANDARD EQUIPMENT.

I was going down the hill in my development, I made it approximately 2-300ft at 7-10MPH when suddenly there was a loud “bang”. I could not see anything, my airbags had deployed and blocked my field of vision. I ended up hitting an electrical pole. There was no need for the airbags to go off. I could have been killed. There is no airbag recall on my VIN number.

My car's belt had been screeching for a few weeks. I was planning on taking my car in the next day. When i turned my car off, all the electrical went out and it started smoking on the driver's side. I got my car towed to the nearest auto shop. They replaced the battery and belt and yet the electrical was still out. When they tested the fuse, the driver's mirror caught on fire and was smoking. Thank goodness I was not driving when this occurred as that could have been scary. They replaced the fuse, but now I can't auto up / down my window. When I reached out to Subaru, they wanted $200 just to inspect it and $1,000 for a mirror replacement. I told them the situation and they didn't care. I also emailed them and never received a response. I googled this issue and other Subaru cars have had this issue and noted water coming in the mirror so now I'm frightened to get a car wash. There was no warning light or anything unfamiliar.

Back up camera freezes or doesn't work when backing up- almost caused a accident!

5/1/2025

Aug 2025: 2018 Subaru Legacy, 55,500 miles. ISSUE: Rearview camera froze with high-pitch sound for about 10-seconds, then shut off, while in Reverse. I was not aware immediately of this. Did not hit the cars behind me but definitely could have. Unknown if reverse lights affected. Based on online searches, rearview cameras not working is criteria for a recall. BACKGROUND: My main screen is affected by Subaru Screen Delamination (can't use touch at all). My exact model got an extended warranty, but I was not aware of this extension until after it passed. Subaru of America and dealers refused to service it unless I paid full price out-of-pocket. Fast-forward to now, reverse camera being affected. I also see mention online of emergency broadcast radio being blocked, since it does not stay on one channel, due to screen issues. I do not recommend Subaru (not the only issue I've had on a once new vehicle).

P225 / 50 R 18 On 8/28/2021, I noticed my front drivers tired looked weird. Upon inspection, it looked like dry rot. I do have a picture of the tire. I immediately went to Tire Kingdom and purchased a set of of 4 new tires. Tire Kingdom confirmed that the tire looked defective. Still plenty of tread, but the side was separating causing it to not be safe. There was no warning on the car system as the tire had not yet completely separated.

9/2/2021

225/50R18. Factory OEM, serious dry-rot necessitating replacement due to safety concerns. Tires are slightly older than 3.5 years (2018 model year purchased 04/18) with less than 40k miles. All four tires exhibit the dry rot, but the photo is representative of the most serious case of concern. No concerns related to tread wear depth.

The driver’s side airbag of 2018 Subaru Legacy deployed as I was reversing out of a parking lot going approximately 5mph. It has not been fixed due to the company’s negligence. One of Subaru’s accident advocate specialist claimed the engineer found a mysterious brown liquid that caused the airbag to deploy although I had not been in the car for two hours nor was I drinking any substances; especially “brown”. My and other’s safety was put at risk to a degree that is fatal, I was a short distance from the highway to head home. Had I been driving at the normal highway speed in my city (55mph) with the airbag deploying in my face, with others on the road, and inhaling blinding fumes, I can assure you it would’ve been detrimental to my and other’s being. The car was inspected for a few months by multiple Subaru engineers, one of the accident advocate specialist refused to give me any documentation or pictures proving this was the cause. There was absolutely no warning lights or other malfunctions occurring. The car is in great condition, and in a previous accident did not deploy its airbags.

I have tried to contact Subaru of America and let them know this and have had no luck with any type of help with other repairs.

Potentially. 71 complaint reports fall into higher-attention systems such as brakes, steering, engine, powertrain, fuel, suspension, airbags, or electrical components. That does not prove every vehicle has a defect, but repeated complaints in those systems justify a more careful pre-purchase inspection.

How should buyers use complaint data for the 2018 Subaru Legacy?

Use complaints as an early pattern to investigate, not a standalone verdict. Start with the top complaint categories, compare those themes against the recall report and maintenance guide, then inspect service records for evidence that the same problem areas were already addressed. If the same issue appears repeatedly across complaints and recalls, treat it as a real ownership-risk flag.
