The BMW 7 Series might catch your eye when searching for a luxury sedan.

However, not all model years of this prestigious line-up are created equal. Some years are notorious for issues that you should be aware of as a car buyer.

By knowing which BMW 7 Series years to avoid, you can make a more informed decision and avoid potential problems.

In this article, you’ll learn about some important factors to consider when looking for and smartly securing the best BMW 7 Series car.

Bad BMW 7 Series Years

Years to Avoid in BMW 7 Series

First Generation (1977-87)

There isn’t much information on widespread issues for the first-generation BMW 7 Series, so you can feel relatively safe considering these models.

Second Generation (1987-94)

During the second Generation, specifically from 1988-1998, 7 Series models like the 735i, 740i, and 750i experienced various problems.

These problems included electrical faults, fuel pump malfunctions, and leaky radiators. It’s wise to approach these years cautiously and thoroughly examine each unit before purchasing.

Third Generation (1994-2001)

The third Generation faced fewer issues compared to the second Generation. However, the 740i or 740 Li models did have a common problem: oil filter gasket leaks.

These leaks could lead to oil spillages and contamination. If you’re interested in a 740i or 740 Li from this Generation, thoroughly inspect and ensure the gasket is in good condition.

Fourth Generation (2001-08)

Out of the four years that the BMW 745 was in production, the 2003 model should be avoided. This model had numerous cooling system, engine, and steering defects.

Ensure you avoid the 2003 model year when looking at BMW 745 units from the fourth-generation 7 Series.

The E65 7 Series, available during this Generation, also experienced its share of issues. Be extra vigilant when researching these models to avoid potential pitfalls.

Fifth Generation (2009-2015)

The 5th Generation is known for having fewer issues and complaints than previous generations. However, it is still important to thoroughly assess any 7 Series model from this time frame, specifically the 750i, 750Li, 760i, and 760Li.

Sixth Generation (2016-Present)

Although the sixth Generation has not experienced widespread issues, it’s still essential to inspect each vehicle extensively, especially the 750i and 750Li models. As always, ensure you thoroughly test-drive and vet any car before making a purchase.

Common Issues in Problematic Years

Electrical Problems

During the 1988-1998 generation of the BMW 7 series, models like the 735i, 740i, and 750i experienced a variety of electrical faults.

You may encounter issues such as malfunctioning dashboard displays or frequent blown fuses. Make sure to regularly inspect the electrical system, wiring, and connections to prevent any disruptions or costly repairs in the future.

iDrive System

The iDrive System is an in-car communications and entertainment hub. In some years of the 7 Series, you might face software glitches, freezing displays, or slow response times.

To ensure a smooth user experience, keep your iDrive System updated with the latest software, and be prepared for potential hardware replacements if needed.

Transmission Failure

Transmission failure can be a costly and frustrating issue. In certain years, the BMW 7 Series has been known to experience sudden transmission failures, which may lead to jerking, slipping, or complete power loss.

Regular maintenance and monitoring of your transmission fluid levels can help you catch any issues early and prevent major repairs.

Suspension Issues

The BMW 7 Series may suffer from suspension problems, such as noisy or deteriorating parts or total component failure.

To keep your car’s ride smooth and comfortable, inspect your suspension components regularly for signs of wear or damage, and replace them as needed.

Airbag System

Safety is paramount, and the airbag system in some BMW 7 Series models may experience faults or malfunctions.

Pay attention to the warning lights on your dashboard, and get your airbag system checked by a professional if you notice any irregularities.

Power Steering

Power steering is crucial for maneuvering your BMW 7 Series with ease. Power steering issues like leaks or mechanical failures can occur in certain years.

Keep an eye on your power steering fluid levels and seek professional assistance if you experience any power steering symptoms, such as heavy steering or unusual noises.


Brake issues, ranging from worn brake pads to damaged brake components, could arise in the 7 Series.

Regularly inspect your brake parts, replace worn components, and maintain adequate brake fluid levels to ensure a safe driving experience for you and your passengers.

Factors Affecting Reliability

Engine Performance

When considering a BMW 7 Series, knowing different engine options is important.

The V8 and V12 engines may offer more power, but they can also have a greater risk of reliability issues than more modest engines. For example, the 335i and 550i models have faced some problems.

Maintenance and Previous Owners

The reliability of a pre-owned BMW 7 Series depends heavily on its maintenance history and previous owners.

Always verify service records and warranty information to gauge how well the car has been cared for. Remember that your long-term costs may be higher in case of incomplete or improper maintenance.

Climate and Driving Conditions

Extreme climates and rough driving conditions can also affect the BMW 7 Series’ reliability. Icy or sandy environments can lead to more frequent repairs, while heavy city traffic may cause extra strain on the car’s systems. Be mindful of these factors when making your decision.

Mileage and Age

Lastly, consider the vehicle’s mileage and age. High-mileage vehicles, especially older models, are more likely to wear and tear.

As a general guideline, aim for a BMW 7 Series with lower miles and a more recent production year to benefit from the latest build quality and reliability improvements.

Alternatives to Problematic Models

Other BMW Sedans

To avoid problematic BMW 7 Series models, consider exploring other BMW sedans. The BMW 5 Series offers a more reliable option with lower repair and maintenance costs.

You’ll still enjoy the luxurious features and performance you expect from a BMW without the frequent issues plaguing some 7 Series models like the BMW 750Li.

Other Luxury Sedans

If you’re open to exploring other luxury sedans outside the BMW brand, consider Mercedes-Benz, Audi, and Lexus options.

These brands offer competitive performance, styling, and features while maintaining a reputation for reliability.

For example, the Audi A6 and the Lexus LS have fewer reported issues with transmission and heat problems and better track records with doors and other components.

Here are the Lexus LS-460 years to avoid, a completed Audi A6 worst or bad model years to avoid, and different issues you don’t want to deal with!

Consider the luxurious Alpina models, which offer a solid alternative to a used BMW 7 Series.

Current and Future BMW 7 Series

New Technologies and Features

The redesigned 2023 BMW 7 Series brings bolder styling and futuristic tech to upgrade your luxury sedan experience. You’ll enjoy a plusher cabin and more advanced features.

Plug-In Hybrid and Electric Models

BMW now offers the plugin hybrid and electric i7 models, giving you better fuel economy with powerful V8s for a perfect executive sedan choice. Embrace a greener future without sacrificing performance.
