I had my breaks changed back in July, before I left on military orders. When I came back home, I noticed my car wasn't working properly. I would have to press really hard for them to work. Or they would still be engaged like, making it harder for me to drive. As well my car would rev up, in park mode. Or while I'm waiting at a red light or stop sign. I've noticed a popping sound on left side of my car as well. My electric system will sometimes cut off everything in my car. I will have to turn car off wait a few mins and turn it back on. I have had check engine lights come on, I took it to body shop. They ran a test on it. And stated everything was fine, and rest codes. I use this car to and from work. I get frequently maintenance checks. The only thing I've had done to care was replacement of head light from a deer hitting me. I've noticed malfunction prior to deer hitting me. I was told by body shop to report issues.
At times at the first start-up in the morning, and during the day following the vehicle sitting for couple hours (some times less and at other times longer periods), the engine produces a rattling or tapping noise for two or three seconds then it goes away. Often, after an immediate shut-off and restart, the engine produces the same noise for couple seconds then it stops. It's easy to miss the noise if the radio is on or the surrounding is noisy.
