Seeing your Hyundai’s check engine light flicker on can turn a calm drive into a moment of stress. While it’s tempting to ignore the warning, that little amber light is your car’s way of asking for help. At Oceanworks, the premier Berkeley auto repair shop, we’ve helped countless Hyundai owners understand what’s behind that glow — and how to fix it before it becomes a bigger problem.
The check engine light can point to a wide range of issues, from something as simple as a loose gas cap to something as serious (and expensive to fix) as a failing catalytic converter. Many Hyundai drivers encounter OBD-II codes such as:
- P0171 – System Too Lean (often linked to a vacuum leak or faulty mass airflow sensor)
- P0300 – Random/Multiple Cylinder Misfire Detected
- P0420 – Catalyst System Efficiency Below Threshold (commonly a catalytic converter or oxygen sensor issue)
- P0456 – Evaporative Emission System Small Leak (sometimes just a loose fuel cap)
Other common culprits include worn spark plugs, ignition coil problems, or issues with the fuel or exhaust system. Even if your car feels fine, driving too long with the light on can lead to costly repairs.
When you bring your Hyundai to our Berkeley auto care facility, our ASE-certified technicians use advanced scan tools to read these codes and verify the cause. We don’t just replace parts based on the code; we combine the data with a detailed hands-on inspection to ensure we solve the root cause of the problem. Whether you drive a Tucson, Santa Fe, Elantra, or Palisade, we have the training and quality parts to get you safely back on the road.
Taking action early saves time and money. If the light is steady and your car runs normally, schedule a visit soon to rule out anything major. But if the light is flashing or the engine feels rough, pull over where it’s safe, turn off the engine, and call a tow truck — a blinking light often signals an active misfire that can cause damage to your vehicle.
At Oceanworks we believe maintenance shouldn’t be stressful. From clear explanations to quality parts and a 24-month/24,000-mile nationwide warranty, we help Hyundai owners in Berkeley to feel confident every time they drive. If your check engine light is on, don’t wait — bring your car to us, and we’ll handle the rest.
