What Are the Common Faults of Sedans?
3 Answers
Common faults of sedans include engine failure to start, vehicle stalling when shifting gears, and steering wheel shaking while driving. If any of these faults occur, it is recommended that the owner promptly visit a 4S shop for troubleshooting and vehicle repair. Engine failure to start: Mainly check components such as the distributor, spark plugs, and high-voltage lines for moisture due to car exposure to rain or washing. Also, check whether the battery voltage is sufficient. The solution is to first turn off the vehicle, dry the damp parts, and then start the car; use connecting cables to temporarily connect to another vehicle's battery for power supply to start the vehicle. Vehicle stalling when shifting gears: The main reasons are low engine idle speed; the idle shut-off valve is not tightened, or the plug is loose. The solution is to adjust the gear to the correct idle speed according to the vehicle's condition; if the idle shut-off valve or the connecting plug is loose, simply reinsert it. Steering wheel shaking while driving: The main reasons are mud, stones, or other debris stuck on the vehicle's tires; tire deformation due to impact or loss of wheel balance weights; failure to perform a four-wheel alignment after tire replacement. The solution is to remove stones from the tire treads and debris stuck on the wheels. To avoid safety hazards, deformed tires should be replaced promptly, and balance weights should be installed at the nearest auto repair shop. A professional auto repair shop should be sought for a four-wheel alignment to avoid safety hazards.
When I first bought my car, I often encountered annoying issues. The most common was battery problems—it wouldn't start after sitting overnight, especially more frequently in cold winters, likely due to an aging battery or the alternator not charging properly. Then there were the tires, which would frequently lose air or wear unevenly, making the ride feel shaky, so checking tire pressure and replacing them promptly was necessary. And that pesky check engine light would pop up now and then, signaling issues like excessive carbon buildup or a faulty sensor. Brake system problems, like strange noises or a spongy feel, were also concerning—failing to stop in rainy weather would be downright dangerous. Let’s not forget minor electrical glitches, like wipers malfunctioning or the horn going silent, which affected driving convenience. What I learned is that regular maintenance is key—monthly checks of fluids and tires can save a lot of headaches. If problems persist, it’s best to visit a repair shop early and not delay. While these issues may seem minor, ignoring them can disrupt daily commutes.
I've been driving for half my life and have seen the most common car problems. Most start with simple things, like tire issues - insufficient pressure or abnormal wear can lead to unstable driving or even dangerous blowouts. Battery failure is another frequent issue, especially in cold seasons when sudden stalling is common. Then there's the brake system - worn brake pads or low fluid levels can cause delayed braking or strange noises. When the engine warning light comes on, it could be a sensor malfunction or clogged air filter. Electrical problems like malfunctioning lights or AC failure are also troublesome - not having AC in summer is pure torture. My advice is to start with the basics: check tire pressure and battery condition monthly, and warm up the engine before driving. Timely maintenance can extend your vehicle's lifespan and save on repair costs.
