Your Trusted Guide: The Top 5 Vehicle Problems to Look Out For When Shopping For a New Vehicle
Shopping for a new vehicle can be an exciting experience, but it's also a significant investment. Whether you're buying a brand-new car or a pre-owned one, it's crucial to be an informed buyer. Knowing what to look for can save you from a costly mistake down the road.
At Shaw's Automotive, we believe in empowering our customers. That's why we've put together a list of the top five vehicle problems to keep an eye out for when you're car shopping.
1. Engine and Transmission Issues
The engine and transmission are the heart and soul of a vehicle. Any problem with these systems can lead to expensive and complex repairs. When you're inspecting a potential car, here's what you need to do:
Listen to the engine: When you first start the car, listen for any unusual noises. A healthy engine should start quickly and idle smoothly. Ticking, knocking, or grinding sounds can be signs of serious internal problems.
Check the fluids: Look under the hood. The oil should be a clean, amber color, not black or milky. A milky appearance can indicate a blown head gasket, a major repair. Check the transmission fluid as well; it should be red or pink and not have a burnt smell.
Pay attention during the test drive: As you drive, the transmission should shift smoothly. Jerking, hesitation, or delays between gears are red flags. On a test drive, you should also be paying attention to how the car accelerates.
2. Brake and Suspension Problems
Your brakes and suspension are vital for both your safety and a comfortable ride. Don't skip these checks.
Test the brakes: During your test drive, apply the brakes firmly. The car should stop in a straight line without pulling to one side. A spongy or soft brake pedal can indicate a problem with the brake lines or master cylinder. Listen for any squealing, grinding, or pulsating sensations, as these can mean worn pads, warped rotors, or other brake issues.
Inspect the suspension: Drive the car over some bumps or rough road. The car should absorb the impact without excessive bouncing or rattling. Uneven tire wear can also be a sign of suspension problems. To do a quick check, press down on each corner of the vehicle; it should bounce back once and settle.
3. Electrical and Battery Issues
Modern vehicles are packed with electronics, and a simple electrical problem can quickly become a major headache.
Check the dashboard: When you turn the key, all the dashboard warning lights should illuminate for a moment and then turn off. If a "check engine" or "ABS" light stays on, it's a clear sign of an existing problem. If the lights don't come on at all, the seller might be trying to hide an issue.
Test all electronics: Make sure to test everything: the radio, power windows, power locks, air conditioning, heater, and all interior and exterior lights. A non-functional electrical component could be a sign of a bad fuse, or it could point to a more complex and expensive wiring issue.
Look for corrosion: Open the hood and inspect the battery terminals. Excessive corrosion can be a sign of a neglected electrical system.
4. Signs of Flood Damage
Flood-damaged cars can look perfectly fine on the surface but hide a world of problems. Water can wreak havoc on a vehicle's mechanical and electrical systems, and the damage is often irreversible.
Check for a musty odor: A tell-tale sign of water damage is a persistent musty, moldy, or mildewy smell inside the cabin.
Look for water stains: Lift the floor mats and check the carpets underneath for water stains or dampness. Inspect the upholstery for discoloration and look for a "tide line" on the door panels or dash.
Inspect the undercarriage: Look for signs of rust in unusual places, such as on the screws of the dashboard or on wiring.
5. Prior Accident and Body Damage
A car that's been in a major accident may have underlying structural issues that compromise its safety and longevity.
Check the body panels: Walk around the car and look at the gaps between the body panels (the doors, hood, and fenders). They should be uniform and consistent. Uneven gaps or panels that don't align properly can be a sign of a shoddy repair job.
Inspect the paint: Look for mismatched paint colors or textures on different panels. A magnet can also be a helpful tool. If it doesn't stick to a certain area, there's likely Bondo or filler underneath, indicating a repair.
Review the vehicle history report: A vehicle history report from services like CarFax or AutoCheck is an essential tool. It can tell you about a car's accident history, past owners, and title status (e.g., salvage, rebuilt). Always get a report before you buy.
The best way to ensure you're making a smart purchase is to bring the vehicle to a trusted mechanic for a pre-purchase inspection (PPI). A professional can identify hidden problems that a typical buyer might miss. Contact us today at Shaw's Automotive to schedule a comprehensive inspection and get peace of mind before you buy.
