When your semi truck breaks down on the road, it doesn’t just cost you time—it can also cost you money, safety, and customer trust. If you’re a truck driver or fleet operator in San Antonio, TX, you know how important it is to keep your rig in top shape. With the extreme Texas heat, long-haul routes, and heavy traffic in the area, breakdowns can happen when you least expect them.
At B&V Motor Service, we’ve helped countless drivers get back on the road quickly. In this blog, we’ll cover some of the most common causes of semi truck breakdowns in San Antonio and give you simple ways to prevent them before they become serious problems.
1. Tire Blowouts and Wear
Tires are one of the most common reasons trucks break down. Long drives, uneven loads, and hot pavement all put extra strain on your tires. Blowouts on highways like I-35 are not only dangerous, but they can also lead to long delays and costly repairs.
Prevention Tip:
Check your tire pressure before every trip, inspect your tread, and rotate your tires regularly. Make sure your alignment is checked, especially if you frequently drive around San Antonio.
2. Brake System Problems
Your truck’s braking system works hard every day, especially if you’re hauling heavy loads. Worn brake pads, leaky lines, and damaged drums are serious safety hazards that can lead to breakdowns or even accidents.
Prevention Tip:
Schedule regular brake inspections and replace parts before they fail. At B&V Motor Service in San Antonio, we offer full-service brake checks and repairs to keep your truck safe on the road.
3. Electrical and Battery Failures
Batteries and electrical systems are vital to your truck’s operation. In San Antonio’s heat, batteries often wear out faster than expected. Corrosion and loose connections can also stop your truck from starting or cause problems while driving.
Prevention Tip:
Test your battery regularly and keep terminals clean. Replace it as needed, especially if it’s more than three years old or if you notice dim lights or starting issues.
4. Engine Overheating
San Antonio summers can push your truck’s engine to its limit. Overheating is a common issue, especially when coolant levels are low or the radiator isn’t working properly.
Prevention Tip:
Check your coolant regularly and inspect for leaks or damaged hoses. Get your cooling system serviced before peak heat season begins.
5. Fuel System Issues
Problems with the fuel system can lead to rough starts, stalling, or even engine failure. Dirty fuel, clogged filters, or faulty fuel pumps are common problems we see at our San Antonio truck repair shop.
Prevention Tip:
Use high-quality diesel fuel and replace fuel filters based on the manufacturer’s recommendations. Watch for power loss or rough idling, and get your truck checked at the first sign of trouble.
6. Transmission Trouble
A failing transmission can mean the end of your route. Signs like slipping gears, hesitation, or strange noises shouldn’t be ignored. In hilly or high-traffic areas like San Antonio, your transmission can take a beating.
Prevention Tip:
Keep up with regular maintenance and fluid checks. Don’t wait to get your transmission inspected if you notice any unusual performance.
