Common Kia Repairs

Not every Kia is the same. Some models are more likely to experience certain issues than others. Throughout the years we’ve used our knowledge and expertise to identify and tackle some of the most common Kia repairs, including:


Oil leaks – Your Kia engine relies on a variety of seals and gaskets to keep engine oil where it’s needed. These items can deteriorate over time and allow oil to seep through, resulting in constant oil leaks, low oil levels and a danger of oil starvation for the engine and its moving parts.

Carbon build-up – Carbon build-up can occur on direct-injected engines due to their design. Excess carbon deposits can lead to a variety of engine problems, including stalling, knocking and overheating. Excessive carbon build-up can also result in poor fuel economy.

Excess oil consumption – Most engines tend to burn a minute amount of oil between oil changes. With time and age, however, wear and tear on an engine’s piston rings and seals can cause it to consume more oil than expected. Excess oil consumption can cause low oil levels, which in turn leads to improper lubrication, abnormal wear of moving parts, deposits of oil sludge and even severe engine damage.



Noise – If you hear unusual noises upon acceleration or during gear changes, you may need to have your transmission checked. Transmission issues are not uncommon on Kia vehicles, especially those with high mileage.

Slippage – You press the gas pedal, but your Kia takes off sluggishly as if it’s dragging a massive weight behind it. Transmission slippage is a common sign of low fluid levels, worn clutches or fluid that’s overheated.

Leaks – Transmissions have several seals, with the main ones on the fluid pan, the input shaft and on each output shaft. Any leak usually means replacing one or more of the above seals.

Fluid – Healthy transmission fluid appears bright red, but fluid that’s worn out can appear very dark and even smell burnt. In some cases, worn out transmission fluid may contain metal shavings from worn out gears and clutches. These issues merit a thorough inspection of your transmission, at the very least.


Difficulty with starting – As car batteries age, they slowly lose their ability to maintain a full charge and deliver their total cold cranking amps. A battery with a weak charge may give your Kia great difficulty with starting, especially on cold days. The average battery is usually rated to last 3 to 5 years before replacement is recommended.

Battery warning light – If this light appears on your Kia’s dashboard, then it’s a clear sign that something may be wrong with your battery. This usually happens if the battery is unable to maintain a suitable charge.

Dimmed lights – If a battery can’t hold its charge, then you may notice your headlights become dimmer than usual or that your interior lights aren’t as bright as they usually are.

Corrosion – It’s not usual for corrosion to form on battery terminals. This may indicate a bigger problem with your Kia’s car battery, so it’s a good idea to have it checked by one of our expert technicians.


Noise – A grinding, squealing or scraping noise from your brakes could indicate the need for new brake pads. Most brake pads have wear tabs that make such sounds when the pads have worn down to their limits. Scraping, wobbling and vibrating can also indicate uneven rotors.

Pedal feel – If the brake pedal feels unusually soft or spongy to the touch, then that could indicate the need for a brake fluid flush. Brake fluid is hygroscopic, meaning it absorbs moisture over time, which could make the brake fluid less effective under heavy use.
