Common Manufacturer Arguments and How to Counter Them

California’s Lemon Law provides strong protections for consumers who purchase defective new vehicles covered under the manufacturer’s original warranty. But even when a vehicle has repeated problems, manufacturers rarely admit liability without a fight. Instead, automakers and their attorneys often rely on a familiar set of defenses designed to minimize or defeat lemon law claims. Understanding these common manufacturer arguments—and knowing how to counter them—can help consumers better protect their rights and strengthen their claims for a repurchase or replacement.

California Lemon Law Basics

Under California’s Song-Beverly Consumer Warranty Act, a manufacturer must repurchase or replace a vehicle if:

• The vehicle has a defect covered under warranty;
• The defect substantially impairs the vehicle’s use, value, or safety; and
• The manufacturer cannot repair the defect after a reasonable number of opportunities.

While the law strongly favors consumers in many situations, manufacturers frequently challenge whether the defect is substantial, whether enough repair attempts occurred, or whether the issue was even caused by the manufacturer at all.

“The Problem Is Not Covered by the Warranty”

One of the most common manufacturer defenses is that the issue falls outside warranty coverage. Automakers may argue that the defect involves maintenance, wear and tear, cosmetic conditions, or excluded components rather than a warrantable defect. For example, a manufacturer may characterize repeated battery failures as “normal degradation” or describe transmission hesitation as a “performance characteristic” rather than a defect.

How to Counter This Argument

Consumers should focus on consistency and documentation. Repair orders that repeatedly reference the same symptoms help establish that the condition is ongoing and abnormal. If dealership technicians attempted repairs under warranty, that fact itself often undermines later claims that the issue was never covered. It is also important to document how the issue affects the vehicle’s reliability, safety, or usability. A defect does not need to render the vehicle completely inoperable to qualify under California Lemon Law.

“The Consumer Misused or Abused the Vehicle”

Manufacturers frequently argue that the consumer caused the problem through misuse, neglect, unauthorized modifications, or improper maintenance.

Examples may include claims that:

• Aftermarket parts caused the defect
• The owner failed to maintain the vehicle properly
• Off-road driving damaged suspension components
• Charging practices caused EV battery issues.

This defense attempts to shift blame away from the manufacturer and onto the consumer.

How to Counter This Argument

Maintenance records are critical. Keeping receipts for oil changes, tire rotations, inspections, and scheduled service helps demonstrate responsible ownership. Consumers should also be cautious about relying on verbal dealership statements. If a dealership suggests misuse caused the issue, request that explanation in writing. Often, the written repair records do not support the manufacturer’s later litigation position. Additionally, manufacturers must do more than speculate. They generally need evidence connecting the alleged misuse directly to the defect at issue.

“We Could Not Replicate the Problem”

Many modern vehicle defects are intermittent. Electrical failures, infotainment glitches, transmission hesitation, warning lights, charging failures, and software malfunctions may not occur every time the vehicle is inspected. Manufacturers often exploit this reality by arguing that technicians could not duplicate or verify the complaint.

How to Counter This Argument

Consumers should thoroughly document defect occurrences themselves. Videos, photos, screenshots, timestamps, and written logs can become powerful evidence. It is also important to describe symptoms clearly and consistently during every repair visit. Vague complaints like “car acts weird” are less effective than detailed explanations such as:

• “Vehicle lost acceleration while merging onto the freeway.”
• “Charging stopped repeatedly at 42%.”
• “Backup camera screen went black intermittently.”

Even repair orders stating “unable to replicate” still help establish that the consumer repeatedly sought repairs for the same issue.

“There Were Not Enough Repair Attempts”

Manufacturers often argue that they were not given a reasonable number of opportunities to repair the defect. California Lemon Law does not establish a strict universal number of repair attempts, although presumptions may arise in certain circumstances. Manufacturers use this ambiguity to claim that additional repair opportunities should have been allowed.

How to Counter This Argument

Consumers should continue bringing the vehicle in for repair whenever the defect occurs. Each visit strengthens the repair history and demonstrates ongoing problems. Importantly, repeated visits for software updates, inspections, diagnostic procedures, or recall-related attempts may still count as repair opportunities if the defect remains unresolved.

Four unsuccessful repair attempts (or two attempts if the problem involves a serious safety issue) are enough to create a legal presumption that the car is a lemon. Additionally, if the car has been in the shop and out of service for a total of 30 days, regardless of the number of attempts, this fact qualifies for the lemon presumption as well. The effect of the presumption under California lemon law is to shift the burden onto the manufacturer or dealer to prove the vehicle is not a lemon.

“The Defect Does Not Substantially Impair the Vehicle”

Manufacturers frequently minimize defects by arguing that the issue is merely inconvenient rather than substantial.

They may claim that:

• The vehicle is still drivable
• The condition is cosmetic
• The problem does not affect safety
• The issue occurs only occasionally.

How to Counter This Argument

California Lemon Law focuses on whether the defect substantially impairs the vehicle’s use, value, or safety, not whether the vehicle still technically operates. Consumers should explain how the defect affects everyday driving, reliability, resale value, or confidence in the vehicle. Safety-related concerns, repeated breakdowns, loss of power, stalling, braking issues, or persistent warning lights often strengthen this element of a claim.

“The Vehicle Was Fixed”

In some cases, manufacturers argue that the most recent repair resolved the issue, even if the consumer continues experiencing symptoms. This defense is especially common when litigation begins shortly after a repair attempt.

How to Counter This Argument

If the problem returns, consumers should promptly return to the dealership and report the recurrence. Waiting too long can allow manufacturers to argue that the issue was successfully repaired. Maintaining a timeline of recurring symptoms is important, particularly for intermittent defects.

Why Documentation Is the Consumer’s Strongest Tool

Most lemon law disputes ultimately revolve around evidence. Manufacturers rely heavily on repair records, dealership notes, and technical data. Consumers who maintain organized documentation place themselves in a much stronger position.

Helpful records include:

• Repair orders and invoices;
• Photographs and videos;
• Text messages and emails with the dealership;
• Tow receipts and rental car records;
• Notes regarding defect occurrences.

The more consistent and detailed the documentation, the harder it becomes for manufacturers to dispute the existence or severity of the defect.

Legal Representation Changes the Dynamic

Manufacturers deal with lemon law claims every day. They have internal legal departments, technical experts, and established defense strategies designed to limit buybacks and settlements. An experienced lemon law attorney understands these tactics and knows how to counter them effectively. In many cases, proper legal representation shifts leverage back to the consumer and increases the likelihood of a favorable resolution.

Manufacturers rarely accept lemon law liability without raising defenses. Arguments involving warranty exclusions, alleged misuse, insufficient documentation, inability to replicate defects, and claims that problems are “not substantial” are all common tactics used to resist repurchase and replacement claims. Fortunately, consumers can counter these strategies through careful documentation, consistent repair history, and a clear understanding of their rights under California Lemon Law.
