2018 Subaru Legacy Complaints

SUSPENSION,POWER TRAIN,VISIBILITY/WIPER — Filed 10/24/2025

Following an engine-out service at an authorized dealer (Bill Kolb Jr. Subaru), a primary powertrain mounting bolt was left unthreaded by approximately 1 inch, creating an undetected 8,000-mile safety hazard that resulted in extensive drivetrain and suspension component failures. Subsequently, during a diagnostic inspection at another authorized dealer (All American Subaru), heavy rusted metal pliers and loose cowl trim panels were abandoned unsecured inside the wiper cowl tray beneath the windshield, posing a severe roadway projectile and steering/wiper obstruction hazard.

The vehicle on board video entertainment display has stopped working properly. It does not allow any input to the touch screen. And the only way to regain some functionality is by pressing the steering wheel source button. However it works intermittently. And this causes Driver Distraction while driving.

The factory Harman Kardon Starlink touchscreen infotainment system in my 2018 Subaru Legacy has experienced severe touchscreen delamination. The display has developed widespread bubbling beneath the glass and now generates repeated "ghost touches" without any driver input. The system activates buttons, changes screens, opens menus, and performs functions on its own while the vehicle is being driven. These unintended inputs create a driver distraction and make it difficult to use navigation, audio, and vehicle information functions safely. This appears to be a known and widespread issue affecting 2018 Subaru Legacy vehicles equipped with Harman Kardon Starlink head units. The problem is caused by touchscreen delamination and continues to worsen over time. Subaru of America was contacted regarding the defect but declined assistance. The vehicle currently has approximately 117,000 miles. The issue is not the result of damage, misuse, or modification of the vehicle. I am submitting this complaint because the touchscreen operates without driver input and creates a distraction while driving.

The computer screen has an issue where there is bubbling in the lamination causing the screen to go nuts and become a distracting hazard that you can not shut off. It's a known Subaru Legacy issue and should be a recall. A new screen is $2000 plus, which is not feasable for the average person to pay and it's become a safety hazard, ect.

The car 2018 Subaru Legacy 2018, has touch screen delamination on thecentral information/ entertainment screen, which leads to screen freezing, unresponsiveness, and erratic "phantom" inputs. These malfunctions disable vital safety features, like backup cameras, etc.. Subaru has settled claims on this issue, for this vehicle/model, but I do not believe there is an official recall, even though there is obviously a safety issue.

Ghost touch issues with infotainment system (as with many other Subaru models). Cannot use radio, Bluetooth or any screen functions.

ELECTRICAL SYSTEM,LANE DEPARTURE — Filed 01/20/2026

The infotainment touchscreen in my 2018 Subaru Legacy experiences “ghost touch,” where the screen registers inputs without driver interaction and becomes unresponsive. While driving, the screen changes settings on its own and distracts the driver. As a result of the touchscreen malfunction, critical safety features including Blind Spot Warning and Lane Keeping Assistance became disabled. This directly impacted safe vehicle operation. The issue was diagnosed by an authorized Subaru dealership, which confirmed the head unit is defective and requires replacement. Subaru previously issued a warranty extension for this known defect. Subaru of America denied goodwill assistance despite the safety-related nature of the defect.

I experienced an incident of spontaneous acceleration of my vehicle on November 21, 2025. I was driving slowly with my foot on the brake as I was about to make a turn and the engine suddenly accelerated. I slammed down on the brake and the car stopped, but this was extremely frightening.

My wife experienced an unintended acceleration in her 2018 Subaru Legacy. My wife had begun to slowly back out of a parking space in a school parking lot when her 2018 Legacy went into an unintended rapid acceleration in reverse. The car took off in reverse and did not respond to her applying the brakes. Somehow she managed to steer the car which was rapidly acceleration in reverse, virtually uncontrollable, and guide the car down a row of parked cars until she clipped the front of another car at the end of the row and her car came to a stop. Thank God there were no students in the parking lot at the time! The floor mats in our Legacy are Subaru mats that lie flat and in no way would affect the accelerator pedal. As the car was accelerating in reverse, and she had removed her foot from the accelerator onto the brake, the brakes did not slow the car. There is considerable damage to the right rear of the car and trunk. After the accident, when the car was restarted, the accelerator and brakes worked fine and she was able to drive it home from the scene. Thank god students were not in the parking lot!

I have been going back and forth with Subaru of America's Advocacy department for about two weeks now, I purchased my 2018 Subaru legacy back in August of 2023. My head unit in my vehicle has now completely stopped working, I have explained that now my back up camera is now freezing and going black and that it poses a safety risk, but they are not helping me, all they keep telling me was the extended warranty for that specific issue expired in July of 2023. when I checked Subaru's recall website, they have completed out that recall in July of 2025, I have never taken my car in for this issue, I was also never aware of this recall. I have all emails going back and forth with the advocacy department. the recall was for "FMVSS 111" per Subaru advocacy dept. my car has a total of two recalls that have been completed out but it shows they were completed out July 26, 2025, I have had possession of this vehicle since 2023 and was never made aware of any open recalls so I never have taken my car into get anything corrected. this vehicle's star link system is still linked to the previous owner because I can't get it to be linked to me yet.

The display screen for my radio navigation phone etc seems to have a “ghost”. Buttons will rapidly be selected switching radio stations or calling someone on my connected phone or switching to different options available on the screen. It is very distracting while driving and annoying when trying to use for navigation with phone. It has been doing this for quite some time and occurs randomly. I’ve researched this issue online and this has happened to several owners.

While Driving my car, i was not able to use the power locks for my front driver and passenger windows. The power window switch on the driver and passenger door don't work. I have made numerous calls about problems with my windows since I purchased my car, but always came back as the code was reset, and they fixed it temporarily. now i am looking at about a 1500 fix for the power windows, which has been a known problem for my car for years. I went to another shop and they told me this is a step below a recall, but subaru knows about it. to me it seems like this is a safety issue, since the windows cant roll down or up.

The Driver Side Rear View when I started the Car back in January of 2024 after car had been running for 30 Seconds smoke and Fire flames were seen coming through that rear view mirror immediately contacted Subaru of America and was called back with urgency and they fixed this issue but since then I haves a few other issues I believe relate to the wiring inside the vehicle and due to the wiring, which caused the fire. 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.

The infotainment head unit system and screen with the backup camera is completely malfunctioning. There have been instances where the screen glitches out while backing up and I have almost been in a collision. The head unit makes constant random noises, and screen pop ups that cannot be turned off. This makes for highly distracted and unsafe driving as it makes it quite difficult for the car user to maintain sole focus and attention to the roadways and driving. The extreme glitchiness and phantom touches/noises are just as a distraction and safety concern as driving while using a cellphone which is against the law. The infotainment unit should be fully recalled, not just have a warranty extension. The Subaru dealership has inspected the head unit and declared the failure that was part of a now expired warranty extension. The failures came without warning; however the glitches have gotten more frequent and worse over time.

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).
