Twin City Motors Morristown Tennessee

Welcome to Twin City Motors! We understand how frustrating car problems can be. Whether it's a mysterious noise, a warning light that won't go away, or just a general feeling that something's not quite right, we're here to help. This guide aims to address some common issues we see here at our Morristown, Tennessee location, offering practical solutions and a little insight into what might be going on under the hood.

The Dreaded Check Engine Light

The check engine light (CEL) – the bane of many drivers' existence! It's a signal from your car's onboard computer that something isn't working within acceptable parameters. It's crucial to address this promptly, as ignoring it could lead to more serious damage down the line.

Possible Causes and Solutions:

Loose Gas Cap: Believe it or not, this is a common culprit! A loose gas cap can cause a loss of pressure in the fuel system, triggering the CEL. Solution: Simply tighten the gas cap until it clicks. If the light doesn't turn off after a few drives, try replacing the gas cap entirely (around $10-$30).
Faulty Oxygen Sensor: Oxygen sensors monitor the amount of oxygen in your exhaust. A failing sensor can cause poor fuel economy and emissions issues. Solution: Replacing an oxygen sensor typically costs between $100 and $300, including parts and labor. You can attempt to replace it yourself, but you'll need an oxygen sensor socket and a torque wrench for proper installation.
Catalytic Converter Issues: The catalytic converter reduces harmful emissions. If it's failing, you'll likely notice a decrease in performance and a strong sulfur smell. Solution: Catalytic converter replacement is a more significant repair, ranging from $500 to $1500, depending on your vehicle. It's generally best left to a professional.
Spark Plug or Ignition Coil Problems: These components are essential for igniting the fuel in your engine. Worn spark plugs or faulty ignition coils can cause misfires, leading to the CEL illuminating. Solution: Spark plugs are relatively inexpensive to replace (around $5-$20 each), but ignition coils can be pricier (around $50-$200 each). You'll need a spark plug socket, ratchet, and torque wrench for a DIY job.

Important Note: Don't guess! While these are common causes, the CEL can indicate a wide range of problems. The best approach is to get the trouble code read using an OBD-II scanner. You can purchase one yourself for around $30-$100, or most auto parts stores will read the code for free. Bring the code to us at Twin City Motors, and we can give you a more accurate diagnosis.

Strange Noises: What Could They Be?

Unusual noises are often a sign that something is amiss. Identifying the type and location of the noise is crucial for pinpointing the problem.

Common Noise Troubles:

Squealing Brakes: This often indicates worn brake pads. Sometimes, it's just surface rust, which will disappear after a few stops. But persistent squealing means it's time for a brake inspection. Solution: Brake pad replacement typically costs between $150 and $300 per axle.
Grinding Brakes: Grinding is never a good sign with brakes! It usually means your brake pads are completely worn down, and you're grinding metal against metal. Solution: Immediate attention is required. This repair will likely involve replacing brake pads, rotors, and possibly calipers, resulting in a higher cost (around $300-$600 per axle).
Clicking Noise During Turns: This is a classic symptom of a failing CV joint (constant velocity joint) on your drive axle. Solution: Replacing a CV joint typically costs between $200 and $400. Continuing to drive with a bad CV joint can lead to further damage and a complete axle failure.
Knocking Noise from the Engine: A knocking sound, especially when accelerating, can indicate serious engine problems, such as worn connecting rod bearings. Solution: This requires immediate professional diagnosis. The repair could range from replacing bearings (a major engine job) to needing a complete engine rebuild or replacement, with costs ranging from $1000 to $5000+.
Whining Noise from the Transmission: This could indicate low transmission fluid or internal transmission damage. Solution: Check your transmission fluid level. If it's low, add the correct type of fluid. If the noise persists, or the fluid is burnt or contaminated, bring your vehicle to Twin City Motors for a transmission inspection. Transmission repairs can be complex and expensive, ranging from a few hundred dollars for a fluid flush and filter change to several thousand for a rebuild or replacement.

Pro Tip: Record the noise! Use your smartphone to capture the sound. This can be incredibly helpful for our technicians in diagnosing the issue, especially if the noise is intermittent.

Dealing with Fluid Leaks

Finding a puddle of fluid under your car can be alarming. Identifying the color and location of the leak can help narrow down the source.

Identifying Common Fluid Leaks:

Oil Leak: Usually black or brown and greasy. Common leak locations include the valve cover, oil pan, and front or rear crankshaft seals. Solution: The cost varies greatly depending on the source of the leak. A simple valve cover gasket replacement might cost around $100-$200, while a rear main seal replacement (which requires removing the transmission) could cost $500-$1000.
Coolant Leak: Typically green, pink, or orange (depending on the type of coolant used). Look for leaks around the radiator, hoses, water pump, or head gasket. Solution: Hose replacements are relatively inexpensive ($50-$100). Radiator or water pump replacements can cost $200-$500. A head gasket leak is a more serious issue requiring significant labor (potentially $1000+).
Transmission Fluid Leak: Usually reddish-brown and thinner than oil. Common leak points include the transmission pan gasket, seals, and hoses (if equipped). Solution: A transmission pan gasket replacement is a relatively simple repair ($80-$150). Seal replacements can be more involved and costly.
Brake Fluid Leak: Clear to light brown and has a slippery feel. Leaks often occur at the brake lines, calipers, or master cylinder. Solution: Brake fluid leaks are a serious safety concern and require immediate attention! Repairs can range from replacing a brake line ($100-$200) to replacing a master cylinder ($200-$400).

Safety First! Never drive with a significant brake fluid leak. It can compromise your braking system and put you and others at risk.

Warning Lights: What Do They Really Mean?

Besides the check engine light, other warning lights can indicate various problems. Understanding these lights is essential for safe driving.

Understanding Important Warning Lights:

Brake Warning Light: This light can indicate a low brake fluid level or a problem with the braking system, such as a faulty sensor or a parking brake that's still engaged. Solution: Check your brake fluid level. If it's low, add fluid, but be aware that a constantly low level indicates a leak. Have your braking system inspected by a professional.
ABS (Anti-lock Braking System) Warning Light: This indicates a problem with the ABS system. Your regular brakes will still work, but the anti-lock function won't be available. Solution: An ABS sensor or module issue will need to be diagnosed and repaired by a technician.
Battery Warning Light: This light usually means your charging system (alternator) is not properly charging the battery. Solution: Have your battery and alternator tested. A faulty alternator replacement can cost between $200 and $500.
Tire Pressure Monitoring System (TPMS) Light: This indicates that one or more of your tires is underinflated. Solution: Check the pressure in all your tires and inflate them to the recommended pressure (usually found on a sticker on the driver's side doorjamb). If the light persists after inflating the tires, there may be a problem with a TPMS sensor.

Regular Maintenance is Key: Many of these issues can be prevented with regular maintenance. Following your vehicle's recommended maintenance schedule, including oil changes, fluid checks, and inspections, can help catch problems early and prevent costly repairs down the road. Here at Twin City Motors, we offer comprehensive maintenance services to keep your vehicle running smoothly.
