Top 5 Signs Your Subaru Needs Professional Service at Dalton Subaru


Your Subaru is engineered for long-lasting reliability, but like any vehicle, it needs regular maintenance and occasional repairs to stay in top shape. Whether you're commuting through San Diego, heading out on adventures from Chula Vista, or navigating daily drives in National City, it’s important to know when your vehicle is asking for professional attention.

At Dalton Subaru, our factory-trained technicians are here to help with certified Subaru service using Genuine Subaru Parts and the latest diagnostics. If you’re noticing any of the following signs, it’s time to schedule an appointment.

1. Dashboard Warning Lights Are On

The most obvious indicator that your Subaru needs service is an illuminated dashboard warning light. These lights are designed to alert you to specific issues, such as:

Check Engine Light – Could mean anything from a loose gas cap to a serious engine issue.

Brake Warning Light – Signals low brake fluid or a potential brake system problem.

Tire Pressure Monitoring System (TPMS) – Indicates underinflated or overinflated tires.

Even if the car seems to be driving fine, ignoring these lights can lead to bigger problems down the road.

2. Unusual Noises While Driving

Hearing unfamiliar sounds is never a good sign. Here are some noises you should not ignore:

Grinding or squealing brakes – Could indicate worn-out brake pads or rotor issues.

Knocking from the engine – May point to internal engine damage or low oil pressure.

Whining while turning – Could mean power steering fluid is low or a belt is failing.

If your Subaru is making unusual noises, bring it to Dalton Subaru in National City for a quick diagnosis.

3. Strange Smells from the Engine or Cabin

If you notice any of the following smells, your vehicle likely needs immediate attention:

Burning oil – Often a sign of an oil leak or engine overheating.

Sweet smell – Typically means coolant is leaking, which can lead to overheating.

Musty odor inside the cabin – Could indicate mold in the air conditioning system or cabin air filter.

Catching these issues early can help avoid expensive repairs and keep your drive comfortable.

4. Poor Handling or Unusual Vibrations

Does your Subaru feel off while steering or braking? Some common signs of suspension, alignment, or brake issues include:

  • Steering wheel pulls to one side
  • Excessive bouncing over bumps
  • Vibration while braking or accelerating

These symptoms can affect both safety and performance. Our Subaru service team near San Diego and Chula Vista can inspect and realign your vehicle for smoother handling.

5. Declining Fuel Efficiency

If you’ve noticed you're filling up your gas tank more often than usual, it could be a sign of a problem:

  • Dirty air filters
  • Underinflated tires
  • Fuel injector or spark plug issues

Routine maintenance like oil changes, filter replacements, and tune-ups can often restore your Subaru vehicle’s fuel efficiency.
