Spark plug wires play an important role in your car’s electrical and ignition systems.
These wires are responsible for transferring electrical power from the distributor or ignition coil to the spark plugs.
Faulty wires can affect the car’s performance and lead to a number of costly engine problems, but sadly, many people ignore the symptoms of a bad spark plug wire. It’s important to learn how to spot the symptoms of bad spark plug wires and who you can hold liable for this much-needed repair.
Signs of Bad Spark Plug Wires
The following are common signs that your spark plug wires have issues.
1. Visible Damage on the Spark Plug Wires
Spark plug wires may start to dry out over time, so look for cracks in the insulation.
The wires are attached to the spark plugs, which are located on the engine’s cylinder head, so they shouldn’t be too difficult to find.
The wires can also start to melt if they make contact with certain hot components of the engine. Visible cracking or melting is one of the signs of bad spark plug wires.
Make sure you inspect the entire length of each wire to ensure you do not miss any bad or loose spark plug wire symptoms.
2. The Engine is Idling Rough
The car should have a smooth and steady idle, but the engine may develop a rough idle if the spark plug wires are bad.
A rough idle is characterized by shaking, bouncing, or vibrating sensations. This is one of the most common symptoms of bad plug wires.
3. Engine Hesitation
This is one of the most noticeable symptoms of bad spark plugs and wires, and overall, one of the most common car complaints is engine hesitation.
Your car should smoothly accelerate once you apply pressure to the gas pedal. But, the engine may hesitate or hiccup during acceleration if it’s not getting a steady flow of electricity due to faulty spark plug wires.
4. Engine Misfiring
A car engine converts gasoline into energy that is used to power the vehicle in a process known as internal combustion.
Bad spark plug wires can interfere with the electrical current flowing to the engine, making it difficult for the engine to complete the combustion cycle.
An incomplete combustion cycle can cause an engine to misfire, which means your car may jerk, stumble, or briefly lose power. This is one of the most alarming and startling symptoms of bad spark plug wires.
Who is Liable For Faulty Spark Plug Wires?
If your vehicle is exhibiting one or more of these symptoms of bad spark plugs and wires, it’s in serious need of repair.
First, conduct research to determine if you are entitled to free repairs under a vehicle recall. It’s possible that the manufacturer has issued a recall as a result of faulty spark plug wires.
If there is no recall, look into your state’s lemon laws. These laws protect consumers who have purchased new or used vehicles with defects. Consumers who have purchased a “lemon” have the right to return it to the dealership for a full refund or replacement vehicle.
But, is a car with bad spark plug wires considered a lemon? It depends.
Used car lemon laws only cover certain parts of the vehicle
Lemon laws for used cars vary from state to state.
For example, the used car lemon law in New York explicitly states that the ignition system, which includes spark plug wires, is covered. This means your car may be protected by New York’s used car lemon law as long as it meets the other conditions.
New Jersey has a used car lemon law, but it does not explicitly state that spark plug wires are covered.
Pennsylvania does not have a used car lemon law.
The defect must be significant in nature
The lemon laws in Pennsylvania, New York, and New Jersey state that defects are only covered if they “substantially impair the use, value, or safety of the vehicle.”
If you cannot prove that the faulty spark plug wires impair the vehicle, you may not be able to hold the manufacturer liable.
A good example of this issue is found in Patel v. American Honda Co., Inc. In this case, the court ruled that the plaintiff was not protected by the lemon law because he failed to prove that the defect was significant. This case proves that the presence of a defect is not enough to hold the manufacturer liable under the lemon law. If the defect is not significant in nature, the lemon law does not apply.
These laws are complex, so it’s best to speak to an attorney to determine whether or not you are protected by your state’s lemon law. If the lemon laws do not apply, the federal Magnuson-Moss Warranty Act may provide protection.
