Truck Maintenance Failures and Liability: How Negligent Upkeep Leads to Devastating California Accidents

Every commercial truck that travels California’s highways is a potential danger if not properly maintained. These massive vehicles — weighing up to 80,000 pounds — depend on their mechanical systems to operate safely. When companies cut corners on maintenance, the consequences can be catastrophic.

From brake failures on steep mountain roads to tire blowouts on busy freeways, negligent upkeep puts everyone at risk. At BD&J, PC, Attorney Michael Madadi and his team have handled countless cases where poor maintenance practices led to severe injuries and wrongful deaths. Their mission is to hold trucking companies accountable when preventable mechanical failures destroy lives.

The Scope of the Problem: Maintenance Negligence in Trucking

Truck maintenance failures are more common than most drivers realize. Federal data from the Federal Motor Carrier Safety Administration (FMCSA) shows that brake and tire defects are leading causes of large truck crashes in the United States.

In California, where thousands of commercial trucks operate daily, the issue is magnified by long routes, high traffic density, and demanding delivery schedules. Many trucking companies prioritize speed and profits over safety, delaying inspections, skipping repairs, or falsifying maintenance logs to keep trucks on the road.

Common Maintenance Failures That Lead to Accidents

A single mechanical failure can make a 40-ton vehicle uncontrollable. Some of the most common — and deadly — maintenance issues include:

1. Brake System Failures

Brake problems are among the most frequent causes of catastrophic truck crashes. Common issues include worn pads, contaminated fluid, air leaks, or faulty anti-lock braking systems (ABS). When brakes fail, stopping distances increase dramatically — especially downhill or in heavy traffic.

2. Tire Blowouts

Overused or underinflated tires can explode without warning, causing the truck to swerve, jackknife, or roll over. Tire debris often strikes other vehicles, leading to secondary crashes.

3. Steering and Suspension Defects

Loose or damaged steering components make it difficult for drivers to control the vehicle, particularly during turns or lane changes. Neglecting suspension inspections can also lead to dangerous instability on uneven roads.

4. Lighting and Visibility Issues

Broken headlights, taillights, or reflectors reduce visibility, increasing the risk of nighttime or fog-related accidents. California law requires all commercial trucks to maintain functional lighting systems.

5. Engine and Transmission Malfunctions

Ignoring fluid leaks, overheating issues, or engine warnings can result in sudden breakdowns or loss of power while driving — both of which can trigger multi-vehicle collisions.

Each of these issues is entirely preventable with proper maintenance schedules and inspections.

Regulations Governing Truck Maintenance

The FMCSA enforces strict maintenance and inspection standards for all commercial vehicles operating in the U.S. These rules require:

• Regular pre-trip and post-trip inspections by drivers.
• Detailed maintenance records for every vehicle.
• Immediate repair of any defect that affects safety.
• Annual Department of Transportation (DOT) inspections by certified mechanics.

California also enforces state-specific requirements through the California Highway Patrol’s Biennial Inspection of Terminals (BIT) Program, ensuring commercial fleets remain compliant.

When trucking companies fail to meet these obligations, they can be held legally liable for any injuries caused by their negligence.

How Negligent Maintenance Leads to Legal Liability

In a truck accident case, proving that poor maintenance caused the crash is key to establishing fault. Trucking companies, fleet owners, and maintenance contractors can all share liability when:

• They ignore mechanical warnings or inspection reports.
• They fail to replace worn or defective parts.
• They falsify maintenance logs to appear compliant.
• They pressure drivers to operate unsafe vehicles.

Under California law, these actions can be considered negligence per se, meaning that violating safety regulations automatically demonstrates fault.

How BD&J, PC Proves Maintenance Negligence

Attorney Michael Madadi and the legal team at BD&J, PC employ a meticulous, evidence-driven approach to uncover maintenance failures. Their process often includes:

Securing vehicle maintenance records and repair logs.

Obtaining black box (ECM) data to detect pre-crash mechanical warnings.

Interviewing drivers and mechanics about inspection procedures.

Collaborating with forensic engineers to analyze failed components.

Reviewing corporate policies on maintenance scheduling and reporting.

These investigations often reveal patterns of systemic neglect, where companies knowingly risked public safety to save time or money.

Real-World Example: Brake Failure on a California Grade

Consider a truck descending the Grapevine on Interstate 5 — one of California’s most treacherous routes. If the truck’s brakes have not been serviced properly, the driver may lose control entirely. In such cases, the driver is often blamed, but the real cause lies with the company’s failure to maintain the braking system.

Through expert reconstruction, BD&J, PC can prove the driver was operating a vehicle that should never have been on the road — shifting liability to the trucking company or maintenance provider.

Compensation Available to Victims

Victims of maintenance-related truck accidents in California may be entitled to significant compensation, including:

• Medical expenses: Hospitalization, surgeries, physical therapy, and future care.
• Lost wages and earning capacity: For missed work or permanent disabilities.
• Pain and suffering: Physical pain and emotional trauma.
• Property damage: Vehicle replacement and related losses.
• Loss of enjoyment of life: Impact on daily living and relationships.
• Punitive damages: When companies show reckless disregard for safety laws.

BD&J, PC ensures that every category of damages — both economic and non-economic — is fully documented and pursued.

Challenges Victims Face Without Legal Representation

Trucking companies and their insurers move fast after accidents. Their goal is to limit financial exposure by:

• Blaming the driver or another vehicle.
• Repairing or destroying evidence quickly.
• Denying access to maintenance records.
• Offering quick settlements before victims know their rights.

Without an experienced attorney, it’s nearly impossible to counter these tactics. BD&J, PC acts immediately to preserve evidence and prevent corporations from covering up their negligence.

The Importance of Acting Quickly

In maintenance-related accidents, evidence like repair logs, black box data, and mechanical components can disappear within days. California law also limits personal injury claims to two years from the date of the crash.

Hiring a lawyer early ensures that:

• Crucial documents are preserved.
• Mechanics and witnesses are interviewed promptly.
• Legal notices (spoliation letters) are issued before evidence is lost.

Early action can make the difference between a denied claim and full compensation.

How BD&J, PC Supports Victims Across California

With over $1.5 billion recovered for clients statewide, BD&J, PC is recognized as one of California’s top personal injury firms. Under Michael Madadi’s leadership, the pre-litigation department is dedicated to:

• Detailed case preparation and strategy.

• Client-centered advocacy focused on compassion and results.

Their track record demonstrates that justice for truck accident victims starts with experience, persistence, and attention to detail.

Holding Negligent Trucking Companies Accountable

Every truck on California roads has a duty to operate safely — and that duty begins long before the engine starts. When companies neglect maintenance and put profit over people, they must be held accountable.
