Warning Lights

A warning light on your dashboard is your vehicle’s way of saying something isn’t right, but it doesn’t always tell you what. At Reliable Auto Repair, we use professional-grade diagnostic equipment to find out what’s going on beneath the hood.

From check engine lights and ABS warnings to TPMS and transmission alerts, our ASE-certified technicians will scan your system, explain the issue in plain language, and perform the necessary repairs to get everything back in working order. Don’t let dashboard lights go unchecked—early diagnostics can save you time and money in the long run.

Common causes of warning lights:

• Oxygen sensor failure
• Loose gas cap
• Catalytic converter issues
• Faulty spark plugs
• Battery or alternator problems

We’ll help you decode the message and fix the issue, before it turns into a breakdown.

What Do Dashboard Warning Lights Mean?

Dashboard lights can indicate anything from minor maintenance reminders to serious safety issues. Here are a few of the most common lights we see:

• Brake System Malfunction – A red brake light or “BRAKE” warning could mean worn brake pads, low fluid, or a serious system failure. Have your vehicle’s brake system inspected right away to stay safe.
• Reduced Engine Performance – Often called “limp mode,” this warning means the engine has limited power to prevent damage. It’s a sign that something’s wrong—schedule diagnostics as soon as possible.
• Transmission System Malfunction – This light suggests your transmission isn’t shifting properly or has a fault. Catching it early can help avoid expensive repairs.
• Charging System Malfunction – This light sometimes look like a lightning bolt or battery and indicates an issue with the battery, alternator, or electrical system – bring it in and don’t wait until the car won’t start!

Why Choose Reliable Auto Repair for Diagnostics?

Diagnostics is a word that is used frequently, but to us, it means getting to the bottom of what exact component is giving your vehicle a hard time. We see a lot of commercials advertising “free diagnostics”, when in reality it is often nothing more than pulling a code and sending you on your way with more questions than you originally came in with. We use the code in order to narrow down what specific vehicle system the car’s computer is unhappy with and then actually test the parts that may be responsible for the code to come up. The fact that parts are not cheap and your time is valuable is why Reliable Auto Repair is not in the business of guessing – we’re in the business of diagnosing.
