The car is constantly throwing codes for faulty emissions system problem and parking brake problem but the car runs fine. The dealership will not do anything unless I pay them a fee to diagnose it and then they suggest replacing the catalytic converter even though it's very likely a faulty fuel hose or faulty sensor. This needs to be recalled and fixed immediately
I recently got my rotors replaced and the car stutter while braking. Also, this happened before I replaced rotors.. the transmission is slow and won't shift to merge highways. I don't know if its the transmission or the brake lines.. I guess it's the transmission trying to drop gears for engine braking and it starts stuttering.
