My car spontaneously burst into flames after I parked it. I had left the car parked and locked in a parking lot next to a rental house and went in to prepare dinner. 20 minutes later my friends arrived at the scene and alerted us to the fact that my car was engulfed in flames. It seems that the fire originated in the engine somehow, but exactly what started it is unclear. There was no accident or collision, and no foul play. Security cameras in the area couldn't see much, but indicate that the vehicle burst into flames pretty much just after I had left it parked and locked.
I was in a parking lot at a near-complete stop. I needed to nose the car about 18 inches to move it all the way into the spot. I lightly touched the accelerator to inch the car forward, and it shot forward as if some outside force had stomped on the accelerator. The car jumped the sidewalk and slammed into the wall of the building. The car inner body bent and the car is totaled. The airbags did not inflate. The passenger in the passenger seat sustained a fractured sternum and two broken ribs from going into the seatbelt. The driver sustained a sore neck and dizziness.
At low rate of speed, while parking vehicle accelerated without warning and damaged 3 cars . This happened previously with separate family drivers without damage. This is a serious defect and could potentially cause serious injury or death. This was not driver error. the car lurched forward with absolutely no gas pedal involvement. The previous times it happened at a stoplight with enough room in front to hit the brake. Not this time.

My 2016 Subaru OUTBACK has experienced 6 separate incidents where my vehicle battery was inexplicably drained, and hence the entire electrical system was shut down. I was unable to start it without an external boost in each occasion. Fortunately these incidents posed no safety threat to me or others as the car was parked at my home, or in a parking lot. Unfortunately, the problem has not been reproduced or confirmed by my Subaru Dealer, Gillman, in Schertz, TX although extensive diagnostics were performed on 2 occasions by Gillman. My OUTBACK has not been inspected by manufacturer, police, or insurance representatives. There were no warning lamps illuminated because of a total electrical failure, and no other symptoms of the problem prior to the 6 failures. The dates for the 5 incidents of total electrical failure are the following: (1) 6/18/2018 at 1240 Kahili Street, Kailua, HI. …
Recently, My daughter noticed the strong smell of exhaust in the car. It turns out the there is a leak in the exhaust manifold. Subaru issued SERVICE PROGRAM BULLETIN WUJ-95R to address a issue where a bellows in the exhaust cracked and allowed the leakage of exhaust gases in front of the CC, releasing noxious gases into the air and into the driver compartment. Problem is they only applied this to a small amount of the production of the 2016 outback. This issue has been occurring on 2015 to 2019 models since and they did not include them in the recall. To fix this issue because of a design flaw the CC (Catalytic Converter) also needs to be replaced at a cost of over 3000 dollars. My ask is that they should extend this recall to cover all the cars with this design as it is a serious health issue to drivers of the cars. …
The left front drive axel cracked while we were driving on an overpass connecting two highways. We didn't hit or bump anything. The car just stopped, like the brakes were slammed on, except the brakes didn't work. As we were on an incline, the car started rolling backwards, but fortunately the emergency brake worked. It happened so abruptly, I wasn't able to fully pull off the road and my children in the back seat were screaming for their lives as truck after truck whizzed by rattling our car with their horns blaring missing us by inches. The police and fire trucks eventually blocked us from traffic until we could get a tow. The engine worked, but we couldn't get into any gear. The mechanic said it must've been a faulty part to have gone like that. When the axel broke, it damaged the front differential and the transmission so the car isn't very drivable. …
My 2016 Subaru Outback CVT transmission has exhibited an intermittent jerking and grabbing sensation when accelerating from a stop, worse when cold, since at least February 2023. This is a known defect covered under Subaru warranty extension bulletin 16-115-18. February 2023 - An authorized Subaru dealer documented the complaint in writing. The technician stated the vehicle never warmed up during the test drive and dismissed the concern. The CVT issue was never repaired. I was never informed of Subaru's CVT warranty extension program. February 17 2026 - seven days before my warranty expiration - the same authorized Subaru dealer physically identified and documented a CVT oil pump cover leak. The same jerking complaint was again documented in writing. No repairs were made and the warranty expired one week later. …
