On some engines a sticking variable valve timing valve can cause the Check Engine light (MIL) to illuminate. Replacing the valve and a software update will address this issue.
A faulty brake master cylinder reservoir filter can cause the brake system indicator to illuminate after a cold start and then go off. Replacement of the reservoir filter will commonly fix this problem.
Certain models can have a crowned rear brake drum that can cause a vibration when braking. The rear drums will have to be replaced to correct this issue.
The front brake rotors can warp and cause a vibration when braking. The rotors will need to be machined or in cases where they are worn to thin, replaced to correct this issue.
A fluid leak may develop from one or both front suspension struts. Replacing the struts (usually in pairs) will be necessary to take care of the problem.
A refrigerant leak may develop from the AC evaporator causing the AC to blow warm air. Verifying failure of this component is difficult. A good shop will use leak detection dye to verify a failing evaporator.
On certain models the drivers seat bushings can wear out and the seat can rock back and forth. Replacing the bushings are needed to repair this issue.
