2018 Subaru Legacy driver assist problems

LANE DEPARTURE: BLIND SPOT DETECTION

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.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

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.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

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).

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

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

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.

LANE DEPARTURE: WARNING

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.
