For the past six months my car has been popping and knocking in the front end so I replace my front lower control arms and it fix that problem and now the parking brake and traction control lights are on and the car doesn't want to accelerate

 

Your parking brake might be stuck on. Lift the rear end and see if the wheels turn freely. This could be your acceleration problem. On the TC light being on, check to make sure the brake fluid reservoir is at the full mark.

 

I am having this as well. However, I have not replaced anything, these dash lights just started coming on about a week ago. Any help would be greatly appreciated!

 

Check to make sure the brake fluid reservoir is at the full mark.

 

If your reservoir needs fluid you may have a leak in the system, or it is close to time to change your brake pads.

 

BLUF: You probably need to add brake fluid. I had this same issue but it was a couple weeks after I had the front rotors turned. I called the brake shop and the guy said its possible they didn't top off the brake fluid and I was more than welcome to come by so they could do it. I checked the fluid level when I got home and it was very low. I added brake fluid to the reservoir and the lights haven't come on since then.
