Common BMW Defects That Could Qualify for Lemon Law Claims

A BMW is a status symbol. After all, it is “the ultimate driving machine.”

The luxury brand consistently earns high praise from drivers and industry experts alike. BMW ended 2024 with the most number-one-ranked vehicles in its class - showcasing its commitment to quality and innovation.

However, even the best automakers have their shortcomings.

Some BMWs come off the production line with irreparable defects. If yours is spending more time at the repair facility than on the road, you may have a case under BMW lemon laws.

In this guide, we’ll take a closer look at some common BMW defects and why they could qualify for lemon law protection.

What Counts as a Lemon in California?

Lemon laws exist to protect car buyers from vehicles with serious defects. To qualify as a lemon in California, a vehicle must:

• Be covered under the manufacturer’s warranty when the defect or issue was first reported.
• Have a defect that substantially impairs the car’s use, value, or safety.
• Have undergone a reasonable number of repair attempts by a manufacturer-authorized service center to address the defect.
• Have been out of service for repairs on the defect(s) for a total of at least 30 days.
• Not have a defect or issue caused by driver misuse, neglect, or improper maintenance.

**Note:

Under AB 1755, lemon law claims must also be filed within one year after the warranty expires and no later than six years from the vehicle’s original delivery date. Also, most standard used cars sold with only the balance of the factory warranty no longer qualify. Protections are now generally limited to new cars and manufacturer-certified pre-owned (CPO) vehicles purchased with a new warranty.

If your BMW meets these conditions and you have the necessary evidence, you can file a lemon law claim. Once your case is validated, the manufacturer must provide you with a buyback or a replacement vehicle.

Over our years of practicing lemon law in California, we’ve seen many lemon BMWs with the following defects.

1. Timing Chain Failures

Powerful engines are a hallmark of BMW, but certain models equipped with N20 and N26 engines have been prone to timing chain failures.

The timing chain synchronizes the engine’s valves and pistons. When it stretches or fails, it can cause catastrophic damage like engine misfires, poor performance, or complete engine failure.

Any form of engine trouble is a major safety concern that should be addressed immediately. If your BMW exhibits signs of timing chain issues - such as rattling noises, loss of power, or dashboard warning lights - we recommend taking it to a manufacturer-certified mechanic as soon as possible.

If the problem persists despite multiple repair attempts and your car is still under warranty, you may have grounds for a lemon law claim. Reach out to a BMW lemon law lawyer to explore your legal options and potential remedies.

2. Defective Batteries

BMW batteries are routinely criticized for being unreliable. Many owners report that they only last a few years before needing to be replaced. The most common battery-related issues include sudden failures, charging problems, and reduced efficiency in colder climates.

A weak or failing battery can leave you stranded without warning. So, it’s non-negotiable to have it tested or replaced by a manufacturer-certified mechanic to prevent unexpected breakdowns. Should the issue resurface repeatedly, you may be in lemon law territory.

3. Fuel System Issues

Faulty fuel systems are a chronic concern with some BMW models. The brand issued three separate recalls in 2010, 2015, and 2021 for problems related to the high-pressure fuel pump.

Fuel pump failures are dangerous because they can lead to power loss, engine hesitation, or an inability to start the vehicle. If your BMW is experiencing fuel pump issues, you’ll need to have it serviced immediately.

In this regard, be sure to check if your vehicle is part of an open recall. Repairs for recall-related defects are usually covered by the manufacturer.

Vehicles still under warranty that continue to experience fuel pump problems despite repeated repairs may be eligible for a buyback under the BMW lemon law.

4. Steering and Suspension Problems

A damaged, sluggish suspension takes all the joy out of driving a BMW. Owners frequently complain of:

• Vibrations at higher speeds, caused by worn bushings, defective control arms, or improper wheel alignment.
• Power steering failures where the system loses assist or stops working altogether.
• Air suspension leaks that result in uneven rides, reduced comfort, and expensive repair bills.

Steering and suspension problems can make your car unpredictable and uncomfortable to drive. If your BMW is pulling to one side. Or, if you’re feeling every bump on the road, it’s time to take it to a manufacturer-certified repair shop.

Persistent steering or suspension problems may qualify your vehicle for a buyback or replacement under lemon law. Contact an experienced California lemon law attorney to explore your options and protect your investment.

5. Faulty Automatic Headlights

Automatic headlights make driving easier by turning on and off without needing driver input. However, some BMW owners have faced issues like the headlights not turning on or activating at odd times.

Driving at night or in low-visibility conditions without proper lighting puts you and others on the road at risk. If your BMW’s automatic headlights aren’t working correctly, have them checked by a BMW-certified facility.

How to File a BMW Lemon Law Claim

Finding out your prized BMW is a lemon can be frustrating. Fortunately, owners have the right to seek reimbursement for defective vehicles under state-specific lemon laws.

Here’s how to file a BMW lemon law claim in California.

1. Document Everything

Gather all the necessary documentation, including repair invoices, diagnostic reports, your vehicle’s warranty, and all correspondence with the dealership or manufacturer. Detailed records showing recurring defects and repair attempts can help build a strong lemon law case.

2. Confirm Eligibility

CA lemon laws require that the defect occur during the warranty period, and that the manufacturer has multiple opportunities to fix the issue without success. For most cases, this means:

• At least two repair attempts for a defect that poses a substantial safety risk.
• At least four repair attempts for non-safety-related defects that significantly impair the vehicle’s use, value, or safety.
• A total of 30 or more days (not necessarily consecutive) that the vehicle has been out of service for repairs due to the defect.

Review your warranty terms and repair history to make sure your case meets these criteria.

3. Notify the Manufacturer

Before taking formal action, notify BMW or your dealership about the unresolved defect. In some cases, they may offer to resolve the issue directly or negotiate a settlement without further steps.

If the manufacturer denies your claim or fails to provide a satisfactory resolution, you can proceed with a lemon law case.

4. Hire a Lemon Law Attorney

While you’re free to pursue a lemon law claim on your own, it’s important to remember that manufacturers like BMW have powerful legal teams working to minimize payouts to consumers. Their sole focus is to protect the company’s bottom line, and they’re well-versed in strategies to delay, deflect, or diminish the value of your case.

To level the playing field, consider hiring a competent BMW lemon law lawyer who knows how to navigate the process and hold manufacturers accountable. With professional representation, you’ll have a much better chance of getting the settlement you deserve.

Furthermore, most lemon law attorneys work on a contingency basis, meaning you won’t pay them anything up front. Their legal fee is included in the compensation awarded by the manufacturer.
