Most common problems:

Brake fluid leaks

Hydraulic brake systems rely on brake fluid to function properly, and leaks can lead to reduced braking efficiency or complete brake failure.

Brake pedal issues

Spongy or unresponsive brake pedals can indicate air in the brake lines or a failing master cylinder.

Brake rotor warping

Excessive heat or uneven wear can cause brake rotors to warp, leading to vibrations or reduced braking performance.

Brake pad wear

Worn brake pads can reduce braking efficiency and increase stopping distances.

Master cylinder failure

The master cylinder is crucial for hydraulic pressure; if it fails, the brake system can lose pressure, making braking difficult or impossible.

Brake caliper issues

Sticking or seized calipers can cause uneven braking and increased wear on the brake pads.

Cooling system leaks

The in-line 6-cylinder engine can suffer from cooling system leaks, which can lead to overheating and engine damage.

Head gasket failure

Common in older engines, this can cause coolant to mix with engine oil, leading to severe engine damage.

Timing chain/belt wear

Over time, the timing chain or belt can stretch or wear out, leading to engine timing issues and potential engine damage.

Fuel injector problems

Clogged or failing fuel injectors can lead to poor engine performance, misfires, and reduced fuel efficiency.

Crankshaft position sensor failure

This sensor is critical for engine timing, and its failure can lead to engine stalling or failure to start.

Exhaust manifold cracks

The inline-6 engine can develop cracks in the exhaust manifold, leading to exhaust leaks and reduced engine performance.

Oil leaks

Common in older engines, oil leaks can occur from various seals and gaskets, leading to reduced oil levels and potential engine damage.
