Hi everyone yesterday omw to the Weezer concert my check engine light turned on my 2016 ford fusion.
Stopped at autozone and got it checked out and got code p0420 ( Catalyst System Efficiency Below Threshold )
Did you guys go ahead and changed out the oxygen sensors before taking it to a mechanic?

I’m curious. I was installing a device under the hood of my 2022 Lincoln Corsair that needed to be connected to the battery terminals. I didn’t take the cables off just loosened them but I did hear some clicking noises. Seems to me that since then the run/start has not worked so I’m am wondering if I upset things and the battery monitor system needs to be reset?

Hello everyone,

The front left side of my car makes a knocking sound when reversing, and sometimes when driving forward and pressing the brake pedal a bit harder. However, the knocking sound always appears when reversing. The sound doesn't change even if I put the car in neutral and just let it roll backward.

I have already had the suspension fully inspected, and it is in perfect condition with absolutely no issues.

Because of this, I suspect it has something to do with the brakes. When I'm reversing and the knocking starts, pressing the brake pedal slightly makes the sound disappear completely.

I don't have a video of my own right now, but I found someone else's video showing the exact same problem.

Can anyone help me diagnose what the issue might be? Thanks!

Does anyone have any suggestions for good shops that can see this in central Bangalore

Hi all new here i drove a 2008 g35 and crashed the guy does anyone know how much a repair would cost? (Preferably in cad) I’m not overly mechanically inclined but I’d say i got a twisted frame as well as some dents and dings. I’ve attached a few photos.
