Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Following are two main issues, causality/correlation uncertain. After the Subaru eyesight failed for about two minutes while underway (dashboard cluster lit up in numerous places, too), the eyesight system reset while driving. Thereafter, the vehicle began to buck (e.g. Lurch forward several inches with a lot of force) when the vehicle's CVT was in drive and I was stopped with the brake depressed at normal pressure. This has happened about six times in the last four days, and I am extremely concerned. The buck is so severe that the first time it happened, I felt like I was rear-ended. …”
NHTSA complaint #10875555, filed 2016-06, 2,000 miles“While driving, exhaust odor detected in cabin causing headaches/nausea and exhaust became much louder starting at roughly 185,000 miles. Discovered Subaru service program bulletin wuj-95 which identifies cracks forming in the bellows section of the front exhaust pipe and its replacement with an updated front exhaust. Contacted Subaru and requested it be covered under the wuj-95. This request was denied as my vehicle already had the updated exhaust pipe . Purchased and installed the kit called-out in wuj-95 myself. …”
NHTSA complaint #11398922, filed 2021-03, 185,000 miles“3.6 liter 6-cyl engine surges after a cold start. When the car is started, the idle speed is high. When the car is put into gear, as the brakes are released and the car begins to move, the idle speed drops. If the car is brought to a stop or a very low (creeping) speed, the idle speed increases, causing the car to lurch. Foot never touches accelerator pedal at all. This behavior causes the car to move unexpectedly after it is brought to a stop by the brakes. …”
NHTSA complaint #10862438, filed 2016-05, 100 miles“Sometimes when starting from a stop or slowing down to make a turn the engine revs up like I was pushing the gas pedal. When this happens ( 4 times in the last 6 months) luckily I was covering the break to slow down or going very slow from a stop. Each time I was turning left or right. I was able to push the shifter into neural. After applying the breaks the engine slows down”
NHTSA complaint #11684180, filed 2025-08“Car battery has discharged on three occasions within the passed 6 months. There is no warning that the battery is failing, turn car off and go to turn on next day and it won’t start. The battery is one yr old and mechanic gave it passing mark when he checked it. When I researched internet to gather more info I found the class action lawsuit describing my problem on other Subarus and felt it should be documented.”
