Power You Can Count On — From Start to Finish

Few things are more frustrating than turning the key and hearing… nothing.
Whether it’s a weak battery, a faulty alternator, or a charging system problem, Rob’s Automotive Repair Center in Clackamas, OR provides expert diagnosis and repair to keep your vehicle starting strong and running reliably.

Our ASE Certified technicians use advanced diagnostic technology to quickly pinpoint the cause of electrical and starting issues — saving you time, money, and stress.

How Your Vehicle’s Starting & Charging System Works

Your vehicle’s electrical system is built around three key components:

Battery: Stores electrical power to start your engine and support accessories.
Starter: Uses power from the battery to crank the engine.
Alternator: Recharges the battery and powers electrical systems while you drive.

If one part of this system fails, your vehicle may not start, charge properly, or run efficiently. Our team tests each component precisely to ensure the real problem is fixed — not just the symptoms.

Signs of Battery or Charging System Problems

If you notice any of these warning signs, it’s time to schedule an inspection:

Engine cranks slowly or doesn’t start at all
Battery warning light on dashboard
Dim headlights or flickering interior lights
Clicking sound when you turn the key
Electrical accessories malfunctioning (radio, power windows, etc.)
Burning smell or whining noise from the engine area

Don’t ignore these signals — small electrical issues can quickly lead to a dead battery or complete breakdown.

When to Replace Your Battery

Most automotive batteries last between 3–5 years, depending on driving habits, temperature, and maintenance.

We recommend:

Inspecting battery terminals regularly for corrosion or wear

I'm late to review Rob's, as they took care of me back in August, but these guys are amazing!!! Carter was the main employee I spoke with over the phone and he was phenomenal. He also came in on his day off to make sure I had … read more my car secured in a safe place until they opened. Corey also really helped when I came in personally and by going through some paperwork to ensure I wasn't being screwed over by the company I had been going to the last several years (which it turned out i kind of had been). Carter and Corey worked together to find me the best ways to handle the situation and have me honest suggestions without making me feel manipulated into paying for maintenance through they're company - they were there to help and make sure that I was safe while driving my vehicle. While being very professional and knowledgeable, they went up and beyond what I could have hoped for. The company understands that life happens and they do everything (within reason) to work with your time and budget to make sure that their clients are well taken care of and that the work that they do is thorough and accurate.I HIGHLY suggest using Rob's Automotive for your vehicle needs because of their honesty, hard work and their excellent customer service.Thank you again, especially Carter and Corey, for helping me get through a rough time with my little car and helping me feel confident that I made the right choices on how to handle my car issues. I will absolutely be coming back!
