When your car starts acting up, it’s easy to brush it off. Maybe it’s a weird noise you only hear sometimes, or a warning light that flickers on and off. But ignoring the signs could leave you stranded—or worse, facing a hefty repair bill. Whether you’re commuting around Somerdale or managing a commercial fleet across the tri-state area, knowing how to tell if your car needs immediate repairs is key to staying safe and avoiding unnecessary breakdowns.

At Schimpf’s Garage in Somerdale, NJ, we’ve seen it all—from minor tune-ups to major engine overhauls on everything from daily drivers to dump trucks. With over 60 years of combined experience in automotive repair, we’re here to help you catch the signs before things get serious.

Here’s what you need to know.

1. Warning Lights Aren’t Just Suggestions

The lights on your dashboard are there for a reason. If any of these come on and stay on, it’s time to act:

• Check Engine Light: This can mean a range of issues—from a loose gas cap to a serious engine malfunction. Don’t guess—get it diagnosed.
  
• Brake Warning Light: If this light comes on, your braking system could be compromised. That’s not something to gamble with.
  
• Oil Pressure Light: Low oil pressure can mean your engine isn’t getting the lubrication it needs, which can lead to severe engine damage.
  
• Temperature Light: An overheating engine can quickly turn into a cracked head gasket or worse.
  

Modern vehicles are equipped with sophisticated diagnostic systems, and when something’s wrong, your car is trying to tell you. At Schimpf’s, we offer advanced diagnostics for all makes and models—commercial and personal—so you’re never left guessing.

2. Strange Noises? Don’t Turn Up the Radio

Odd sounds are often your car’s first cry for help. Common sounds that indicate you need immediate attention include:

• Grinding or Squealing Brakes: This usually means your brake pads are worn down and could be damaging the rotors.
  
• Clunking While Driving Over Bumps: Your suspension might be failing. If left unchecked, it can affect steering and handling—especially dangerous for larger commercial vehicles.
  
• Whining Under the Hood: This could be a failing serpentine belt or an issue with your power steering system.
  
• Knocking from the Engine: That’s a big red flag. It often indicates internal engine damage.
  

A little noise can lead to a big bill if ignored. We’re here to track down the source fast and get you back on the road safely.

3. Leaks Are Never “Normal”

If you see spots in your driveway or a puddle under your vehicle after it’s been parked, don’t ignore it. Here’s what to look for:

• Oil: Usually dark brown or black. Persistent leaks can drop your oil level dangerously low.
  
• Coolant: Often green, pink, or orange with a sweet smell. A coolant leak can lead to overheating.
  
• Brake Fluid: Clear to yellowish and slippery. A brake fluid leak means your braking system is compromised—get this checked immediately.
  
• Transmission Fluid: Typically red or brown. Low transmission fluid can cause shifting issues or complete transmission failure.
  

At Schimpf’s Garage, we don’t just patch leaks—we find the root cause and fix it right the first time.

4. Smoke or Steam? Pull Over

If smoke or steam is coming from under the hood or out of the exhaust, it’s never a good sign.

• White Smoke from the Exhaust: This could mean coolant is leaking into the engine—a possible head gasket failure.
  
• Blue Smoke: Indicates oil is burning in the engine, possibly due to worn piston rings or valve seals.
  
• Black Smoke: Often means the engine is burning too much fuel—likely a fuel system or sensor issue.
  
• Steam from the Hood: That’s likely a coolant system failure. Continuing to drive could warp your engine.
  

Don’t wait to see if it clears up—this is your sign to pull over and call for help. We offer mobile services for commercial vehicles, and fast in-shop repairs for everything else.

5. Unresponsive or Shaky Steering

If your steering feels loose, stiff, or starts vibrating at higher speeds, you could be facing serious suspension or alignment problems. This is especially dangerous on heavy-duty trucks and box trucks, where control and handling are critical.

Common issues include:

• Worn Suspension Components: These affect ride comfort and handling, especially when carrying heavy loads.
  
• Misalignment: This can cause uneven tire wear and poor fuel economy. Our mobile laser alignment service ensures pinpoint accuracy on-site for commercial fleets.
  
• Low Power Steering Fluid: You’ll notice increased effort required to turn the wheel, particularly at low speeds.
  

The team at Schimpf’s Garage specializes in suspension and alignment work for all vehicle types—from compact cars to semis. Whether in-shop or mobile, we keep your ride steady and safe.

6. Transmission Trouble Is Nothing to Ignore

Your transmission is what makes your car move, and problems here can get expensive quickly.

Watch for:

• Delayed or Slipping Shifts: Could mean low fluid, worn clutches, or internal damage.
  
• Strange Noises in Gear: Whining or grinding could indicate a problem with transmission bearings or gears.
  
• Burning Smell: Often due to overheated transmission fluid or clutch wear.
  

Early intervention can save your transmission. Don’t wait until you’re stuck on the side of the road.

7. Sudden Drops in Fuel Economy

If you’re visiting the gas station more often but haven’t changed your driving habits, your car might be working harder than it should. Common culprits include:

• Faulty oxygen sensors
  
• Dirty air filters
  
• Misfiring spark plugs
  
• Under-inflated tires or alignment issues
  

Regular car maintenance helps you catch these problems early. At Schimpf’s, we offer comprehensive vehicle service, including diagnostics and inspections to keep your car running efficiently.

8. Vibrations or Shaking While Driving

If your car shakes when accelerating, braking, or even idling, something’s not right.

• Shaking When Braking: Likely warped brake rotors.
  
• Shaking at High Speeds: Could be unbalanced tires or a failing driveshaft.
  
• Engine Vibrations at Idle: Might be worn motor mounts or misfiring cylinders.
  

Ignoring vibrations could lead to serious mechanical issues. A simple inspection can pinpoint the problem fast.
