The brakes may begin to squeak at about the 50 percent wear point. This is due to the size and material used for the brake pads and rotors.  The brake rotor surfaces become uneven, causing a lip to form at the outer edge. This will generally require replacement of the rotors when the pads are worn (pad life varies depending on driving style and terrain).

The bushings for the shifter lever wear out to the point where they break and fall out. This causes excessive movement (loose feel) in the shifter lever and a clanging-type noise when changing gears.

The evaporator temperature sensor can fail, causing the AC compressor not to cycle. If the AC compressor does not turn on, the AC system will not blow cold air. If the compressor is stuck on, the air will be very cold at first, before warming up.

PSE system, voice control module, or Tele Aid module failure can cause a lack of audio. These same modules can also cause dead battery conditions when they fail to "time out." Many electronic control modules are active even when the engine is off. If these modules stay active, they will drain the battery, which is why they have a timer built into the modules. The timer shuts down the modules after a preset amount of time (timing out). If a module does not time out, it will stay active and drain the battery.

Brake lamp housings can melt, resulting in a loss of contact for the brake light bulb holder. If this happens, the brake light will not work. Replacement of the damaged lamp housing should correct this problem.
