First oil change at 5,850 miles no problem. after second oil change at 11,948 miles, vehicle became undrivable as it stumbles and loses power between 2,000-2,700 rpm. dealer has repeated oil change 3 additional times as they are not certain if they may have overfilled the engine (known subaru issue). they have also replaced the exhaust, catalytic converter, air filter, intake system, and transmission, all to no avail. disconnecting the battery and grounding the cables to discharge all capacitors provided temporary relief, but the problem returned within 36 hours and 200 miles. now entering 3 weeks and 600 miles of troubleshooting and test driving by the dealer, but they have been unable to fix the problem. the car is still unsafe and undrivable, as 2000-2700 rpm is the heart of the power band that is always used when driving.
Engine does not brake when going downhill as the manual says it should. my previous outbacks (2006, 2011, 2017) did have engine braking. regional service office suggested i place the car in cruise control in order to control the speed. car picks up speed quickly, so using the brake pedal is the best option. however, the problem is no engine braking when there should be at least some. this is dangerous on any hill. second, steering is problematic. first, there is to much play in the steering wheel. second, when in cruise control, the steering wheel seems to have a mind of its own, especially on curves. i am constantly having to work at controlling the steering wheel. it's very tiring. the third issue is in regard to the navigation system showing inaccurate speed limits. i noticed this problem had been reported as early as february 2019. i have had this vehicle since may 31, 2019.
