I’ve had issues with my air conditioner not working properly and now making a loud humming sound. Also my car is very sluggish and my motor is very loud when the car is running. Sometimes it dsn’t want to shift exactly when it should it takes longer and I have to take my foot off the gas to let it shift. My car keeps running out of oil every time before the designated oil change time and mileage. This really worries me and no lights show on my dash when my oil pressure gets low which is alarming because it got low one time and I could hear the pistols rubbing together, I knew immediately I needed oil. Sure enough I put oil in the car the noise stopped and I went and got an oil change the next day because I was worried about my car. The oil issue has happened multiple times..
