Insights from Automotive Technicians & Industry Experts

Cars today are more reliable and longer-lasting than ever—but only if they’re driven with care. Too often, everyday drivers unknowingly develop habits that silently chew through vital components, leading to costly repairs or premature breakdowns.

We spoke with seasoned automotive technicians and industry pros to round up some of the worst driving habits that wear out your vehicle faster than it should—and how to avoid them.

🔴 1. Redlining the Engine Too Often

Revving your engine to its limit may sound exciting, but consistently pushing it to the redline can shave years off its life.

“I’ve seen cars that sounded like they were falling apart at 60,000 km because of how aggressively they were driven,” one technician noted. “Meanwhile, grandpa’s old car with 280,000 km still purrs like a kitten.”

What it damages: Engine internals, pistons, valve train, bearings
Better habit: Accelerate steadily and let the engine do its job without maxing out the RPMs.

🛞 2. Aggressive Acceleration = Driveline Damage

Slamming the gas not only stresses your engine—it also strains your transmission, CV joints or U-joints, wheel bearings, and even your differential.

What it damages: Transmission components, drivetrain, wheel bearings
Better habit: Apply smooth, gradual throttle inputs to protect the drivetrain and improve fuel economy.

🚧 3. Flying Over Driveway Bumps or Curbs

Charging into a driveway or over a curb at speed sends a concentrated shock through your suspension—especially on one side.

“You’re hammering the tie rod ends, sway bar links, steering rack, struts, and wheel bearings—often on just one tire,” explained a front-end specialist.

What it damages: Tie rod ends, sway bar links, struts, alignment, wheel bearings
Better habit: Slow down before entry and take the incline or bump at an angle when possible.

🛣️ 4. Speeding on Bumpy Roads

Going fast on uneven roads may save time, but it’ll cost you in the long run.

What it damages: Suspension bushings, steering bushings, tires, struts
Signs of trouble: Leaking struts, uneven tire wear, poor handling
Better habit: Drive slower over uneven surfaces, and avoid repeat hits to the same suspension components.

🕳️ 5. Hitting Potholes at Speed

This one’s a classic—and a wallet drainer.

“I’ve seen bent rims, popped tires, leaking struts, busted bearings, and damaged steering parts—all from one pothole hit too fast,” shared one technician. “The customer totaled the car rather than fix it.”

What it damages: Rims, tires, alignment, wheel bearings, suspension
Better habit: Keep your eyes up. Avoid potholes or slow down as much as safely possible before impact.

---

🟡 6. All Gas or All Brake—No In Between

That “on/off” driving style might get you there fast, but it destroys your brake system.

What it damages: Brake pads, rotors, brake calipers, brake master cylinder
Better habit: Learn to modulate both the gas and brake pedals for smoother stops and longer component life.

---

🚗 7. Tailgating and Stop-and-Go Traffic Stress

Following too closely in traffic leads to excessive braking and gear shifting—especially in automatics.

What it damages: Brake pads, brake rotors, transmission components
Better habit: Leave more space and coast when possible to reduce mechanical stress.

---

💨 8. Driving at High Speeds (80+ MPH)

Sustained high-speed driving stresses every major moving part in your car.

What it damages: Engine, transmission, CV joints or U-joints, wheel bearings, even tires
Better habit: Stay within speed limits. Not only is it safer, but it dramatically reduces wear on high-cost components.

🚘 Final Thoughts: Treat Your Car Like a Machine That Works for You

Your car isn’t just a tool—it’s a system of precision-engineered components designed to work together smoothly. When you develop bad habits, you force these parts to fight against physics, wear faster, and fail sooner.

✅ Drive smart
✅ Stay smooth
✅ Avoid unnecessary stress

Your car will reward you with more miles, fewer repairs, and a better driving experience.
