general problems of the 2018 Subaru Impreza

March 2023 I had all 4 rotors & brakes replaced. About 2 weeks after, doing 65 mph on highway 79 I had to lightly apply my brakes. After letting off the brake all of a sudden my whole car, steering wheel, etc started shaking. I pulled off the road thinking something broke but nothing was. A couple months later on 79 it did it again without applying my brakes. It's happening more often and the shaking is getting more severe to where my car is either going to fall apart or bounce off the road or into another car. I'm terrified when this happens because I don't know what's going to happen. I won't even put my grand children in my car. One if my CO-workers had the same thing happen to her Subaru. She said after her mechanics did some investigating, they found that there was an issue with the replacement rotors warping and causing the car to shake terribly. This is a severe safety issue and really needs to be investigated. Also a year warranty on these defective parts is too short.

Suspected defective and/or faulty brake booster or brake hose on the front left tire. Car starts violently shaking/shuddering when easing onto the brakes (once the brakes have warmed up for my daily commute to work). Resulting vibrations travel up the steering column to the steering wheel, and into the cabin. The car will then pitch its nose in various directions; it feels as though the front left brake is being grabbed and not properly released. Taken to a Subaru dealership multiple times. New brakes and rotors installed in July 2022; other components of the brake (calipers, pistons) were inspected in Aug. 2022 and appeared fine. However, on inspection (08/2022) the newly replaced rotor on the front left tire was already showing visible wear/damage (white scalding) due to excessive heat generated while braking. I have taken the car to be serviced at a dealership multiple times & have been told the shaking "couldn't be replicated. " I recreate it every day I drive to work (350 miles every week). *please* see the video linked to a third-party website: https://imgur. Com/a/wfvlv0a other symptoms: the engine starts and runs roughly despite recent oil changes. Obdii code p0300 (random/multiple cylinder misfire detected) was detected by a personal obdii scanner, although I don’t know if that issue is related. Ignition timing advance for the 1st cylinder is near red zone. Please help. .
