Modern automobiles are complex machines, which is another way of saying that many things can go wrong with them. From an irritating squeal when you step on the brakes to an engine that dies occasionally when you reach a stop sign, a car can signal that some mechanical attention—perhaps minor, and perhaps not—may be needed.
Few of us could afford to pay for immediate repair of every little oddity we notice about our vehicles, but there are some ominous signs you shouldn’t overlook. Don’t ignore or put off getting help for these four serious warning signs.
1. Gear Shifting Issues
Whether you drive an auto with a manual gearbox or have an automatic, your car’s transmission is a critical link between your engine and the wheels that transfer power to the road. The automotive newsletter Auto Express lists transmission trouble as the number one major breakdown affecting a range of used vehicles.
If your manual transmission or transfer case becomes noisy or physically difficult to shift, don’t put off having a shop diagnose the problem. Similarly in an automatic, if the transmission begins shifting when it shouldn’t or not shifting when it should, seek assistance as soon as you can. Putting off repair of these problems could increase the damage and cost—and could also render your vehicle suddenly undriveable.
2. Unusual Noises
A modern auto contains thousands of parts, and many of them must interact in motion for your vehicle to perform correctly. In addition to the engine and transmission, many vehicles also have a clutch, differential, transfer case (on four-wheel-drive vehicles), jointed drive shafts and other moving components.
Unusual noise occurring suddenly from any of these could be a warning that serious mechanical failure is looming—and immediate professional help is required.
3. Sudden Unusual Vibrations
If you notice a rapidly developing vibration as your vehicle idles or drives, with or without unusual noise, seek professional mechanical help immediately. This often indicates a critical moving part is failing or has failed, and could endanger not only your car or truck’s longevity, but your safety as well.
Vibration that occurs only when you step on the brake is similarly ominous. Get to a shop at your first opportunity.
4. Reduced Vehicle Performance
All engines, transmissions and other components gradually wear out over time, but a sudden decrease in your auto’s ability to maintain driving speed, idle smoothly at a stop sign or light, or get up to speed quickly and smoothly are red flags warning you that your car may suddenly leave you stranded.
Transmission, clutch, engine component or other serious impending failure can be headed off, but only if you seek help immediately. Shops such as Gearbox Express can give you a rapid diagnosis and estimate, and can perform needed repairs to manual transmissions, clutches, transfer cases, differentials and other key power train components to keep you in the driver’s seat.
Certainly, you might face other problems with your vehicle—brakes, lights, exhaust systems and other components all need regular service—but don’t miss these four major warning signs, or you might find yourself stranded beside the road.
