general problems of the 2019 Subaru Ascent - part 2

We are hearing a thumping or knocking noise in the front right wheel well area. We notice this noise when the car is in motion on a rough road while driving, turning, or braking. The dealership we purchased our car from checked all running gear parts under the car, and steering components, to see if there were any visible problems. After a test drive by mechanic and another service department employee, they could hear the noise, but we're unable to find its source. We are wondering if any other owners of a 2019 Ascent have experienced a similar problem?.

A couple of months ago, my wife started the car and backed off a parking lot. When she pressed the brake and felt wired - the brake could not be pressed down and felt like it's jammed somehow. The car did not stop even she switched the car to parking! it eventually stopped after hit a parked car behind. Because the speed was very low so there was no obvious damage to both cars. But after restarted the car, all the warning lights went on - rab, eye sight, at oil temp, low tire pressure, and the sun roof and sun shade not working.

Have had to jump my battery start using a portable power supply at least 4 times. Various reasons, such as leaving the back hatch open for extended periods, leaving the accessories on for a little over 15 minutes etc. At times it appears to struggle to start as though the battery has not fully charged. These incidents has been happening shortly after the vehicle was purchased. They are happening less to date because I'm aware that I cant use any accessory for an extended period because of the risk of a dead battery.

Hi issue #1: my Subaru never gives the mpg what they promised, on average I get 17 or 18 mpg mixed drive supposed to get 21mpg, whenever I complain to the dealership they give a standard answer about it depends on driving style never attempted to find the root cause. Never had this issue with my previous cars, I used to get the same as what they promised. So I feel not related to driving style. Issue #2: blue smoke came multiple times, so not consistent reproducing not sure. Issue #3. My battery died many times couple of times had called roadside, later I got a jump starter and I have used it multiple times to start my car, and replaced the new battery under warranty and Subaru paid for it, but unfortunately, the new battery I got had also died and got it replaced by warranty.
