Gateway Mobile Automotive

Modern vehicles are complex computers on wheels. When a warning light appears or something electrical fails, you need a technician who understands both the mechanical and electronic systems. Gateway Mobile Automotive brings advanced diagnostic scanners directly to your location in North San Antonio. Our ASE-certified technician will plug into your vehicle’s computer, retrieve trouble codes, and perform systematic testing to pinpoint the exact cause—whether it’s a faulty sensor, wiring issue, battery drain, or alternator failure.

We don’t just guess and replace parts. Each diagnostic session includes a thorough explanation of the problem, your repair options, and a transparent quote before any work begins. Electrical issues can be frustrating, but our methodical approach saves you from expensive trial-and-error repairs. From parasitic battery drains to malfunctioning lights, windows, or infotainment systems, we have the expertise to fix it efficiently. And because we’re mobile, you don’t have to risk driving a potentially unsafe vehicle to a shop. We come to you, diagnose on-site, and often complete the repair the same day.

Customers in North San Antonio choose us because we combine advanced technology with honest, no-nonsense advice. If you’re tired of shops that want to replace everything without a clear answer, give us a call. We’ll tell you what’s wrong, what it takes to fix it, and let you decide—with no pressure, just professional service.

Your brakes and suspension are your vehicle’s most critical safety systems. Squeaking, grinding, pulling, or a spongy pedal are signs you need immediate attention.

Our ASE-certified mechanic arrives with all necessary tools and quality parts to perform brake pad and rotor replacements, caliper repairs, brake fluid flushes, and parking brake adjustments at your home or workplace.

Suspension and steering issues—like uneven tire wear, bouncing, drifting, or knocking noises over bumps—can make your car unsafe and uncomfortable. We inspect shocks, struts, control arms, tie rods, ball joints, and wheel bearings, then provide a clear diagnosis and fair estimate. Because we’re mobile, we can often complete the work in a few hours while you carry on with your day. No towing fees, no waiting rooms, no loaner car hassles.

We take pride in transparent pricing and quality workmanship.
