The Most Common
Lemon Law Defects

When a vehicle has a defect that substantially affects its value, use, or safety, it is commonly referred to as a “lemon.” The question that commonly arises is what types of defects usually affect a vehicle’s value, use or safety? Restated different, what types of problems will make my car a lemon?


It’s important to recognize that each car is distinct, carrying its own set of idiosyncratic concerns that could potentially push it into lemon territory.  With that in mind, the following is a list of serious defects that might lead to a vehicle earning the lemon label:

Engine Problems

The engine domain is rife with potential complications capable of compromising a car’s performance and safety. Among these challenges are:

1.     Stalling: This perturbing phenomenon transpires when an engine unexpectedly shuts down during operation.

2.     Misfiring: A condition where one or more engine cylinders fail to ignite optimally, resulting in uneven or rough idling.

3.     Engine Overheating: Typically triggered by a congested radiator, a faulty thermostat, or leaks in the cooling system.

4.     Engine Pinging or Knocking: A disconcerting auditory occurrence stemming from excessively swift detonation of the fuel and air blend.

5.     Unorthodox Engine Noises: A medley of noises like ticking, knocking, or squealing that raise concerns about the engine’s health.

6.     Decline in Engine Power: Often instigated by clogged air filters, fuel system irregularities, or worn-out spark plugs.

7.     Engine Warning Light: A dashboard signal indicating potential critical issues or mere glitches within the system.

8.     Total Engine Failure: The catastrophic scenario of an engine ceasing to function altogether.

Transmission Turmoil

The transmission bears the responsibility of transferring engine power to the wheels, making transmission issues a weighty safety concern. Among these issues are:

1.     Slipping: Occurs when gears can’t be sustained, leading to elevated engine RPM without a corresponding increase in vehicle speed.

2.     Hesitation: A delay in transmission engagement after depressing the accelerator pedal.

3.     Hard or Delayed Shifting: Involves sluggish or abrupt gear shifts, which can be both untimely and jarring.

4.     Transmission Fluid Leaks: When transmission fluid escapes, it could indicate potential issues with the system.

5.     Burning Odor: Arises when transmission fluid overheats and deteriorates, emitting a distinct burnt smell.

Electrical Malfunctions

Electrical glitches impinge on various aspects of the car’s electronic ecosystem, from the main electrical system to onboard systems like computers, lighting, audio, and more. Notable problems encompass:

1.     Alternator Failure: Impairing battery charging functionality.

2.     Faulty Wiring: Triggers a range of electrical dysfunctions, often a manufacturing glitch.

3.     Electrical Shorts: Can lead to power loss, gauge anomalies, light malfunctions, and even fires.

4.     Gauge Malfunctions: Discrepancies in fuel, speedometer, or tachometer readings are indicative of electrical concerns.

5.     Audio and Navigation Failures: Frequently tied to electrical complications, exhibiting symptoms like static or intermittent power issues.

6.     Dimming or Flickering Lights: Pervasive electrical quandaries that, while not jeopardizing safety, erode vehicle utility and value.

Brake Debacles

Brake issues take center stage in terms of safety implications, serving as a potent factor in classifying a car as a lemon. Notably, this pertains more to inherent defects in the brake system rather than issues arising from owner negligence. Instances include:

1.     Complete Brake Failure: A consequence of deficient system design or installation, exemplified by a malfunctioning brake cylinder causing total loss of braking power.

2.     Vibrations While Braking: Resulting from defective or misaligned brake rotors.

Recalcitrant Repairs

Vehicles may veer into lemon territory if persisting flaws resist dealership attempts at rectification. Even seemingly minor issues can lead to lemon status if they impede vehicle functionality or utility. For example, a convertible’s leaky roof, though not a dire safety concern, could secure lemon status if repairs prove elusive. Likewise, recurrent issues such as persistent whistling from the air conditioning system could nudge a car into lemon territory, hampering its utility and operational soundness despite multiple remedial endeavors.
