The 2017 BMW 740i is a luxury sedan that combines performance with comfort, but how does it hold up in terms of reliability? For auto owners, understanding the reliability of key components is crucial to making an informed decision. This model is equipped with a powerful engine, a smooth transmission, and a sophisticated suspension system, but there are some nuances to consider.
Engine Performance
The heart of the 740i is its 3.0-liter inline-six engine, which is turbocharged to deliver a robust 320 horsepower. This engine is known for its smooth operation and impressive acceleration. However, like any high-performance engine, it requires regular maintenance to keep it running at its best. Owners should be aware of potential oil leaks, which can occur if the engine seals wear out over time. Regular oil changes and inspections can help mitigate these issues.
Transmission Reliability
The 740i comes with an 8-speed automatic transmission that shifts seamlessly under normal driving conditions. While this transmission is generally reliable, some owners have reported issues with rough shifting or delayed engagement. These problems can often be traced back to software glitches or low transmission fluid levels. Keeping an eye on fluid levels and ensuring software updates are performed can help maintain smooth operation.
Suspension System
The suspension system in the 740i is designed for a plush ride, utilizing air suspension technology that adjusts to road conditions. This feature enhances comfort but can also lead to potential issues. Air suspension components can fail, leading to a bumpy ride and costly repairs. Regular inspections of the air springs and associated components are essential to catch any problems early.
Other Key Components
Beyond the engine, transmission, and suspension, other components such as the electrical system and brakes deserve attention. The electrical system in the 740i is complex, and while it generally functions well, issues can arise, particularly with sensors and infotainment systems. Brake components are typically reliable, but it’s crucial to stay on top of brake pad and rotor wear to ensure safety and performance.
In summary, the 2017 BMW 740i offers a blend of luxury and performance, but like any vehicle, it has its quirks. Regular maintenance and attention to key components will go a long way in ensuring that this luxury sedan remains reliable for years to come.
Understanding the 2017 BMW 740i
The 2017 BMW 740i is a luxury sedan that stands out for its combination of performance, comfort, and advanced technology. However, like any vehicle, it has its strengths and weaknesses when it comes to reliability. For auto owners, it’s essential to dive into various aspects of this vehicle to fully understand what to expect in terms of durability and maintenance.
Build Quality and Materials
The build quality of the 740i is impressive, featuring high-grade materials throughout the interior. From leather upholstery to real wood trim, the cabin exudes luxury. However, some owners have reported issues with interior components, such as:

Keeping the software updated and addressing any electronic issues promptly can prevent more significant problems down the line.
Maintenance and Repair Costs
When it comes to maintenance and repair costs, the 740i falls into the higher end of the spectrum. Routine maintenance, such as oil changes and brake servicing, can be more expensive than average due to the premium parts and labor involved. Here’s a breakdown of typical costs:
| Service Type | Estimated Cost |
|---|---|
| Oil Change | $150 – $250 |
| Brake Pad Replacement | $300 – $600 |
| Transmission Service | $300 – $500 |
| Annual Inspection | $100 – $200 |
While these costs can be daunting, staying on top of maintenance can help avoid more significant repairs that could arise from neglect.
Typical Problems and User Feedback
Understanding common issues reported by owners can provide valuable insight into what to expect. Here’s a summary of typical problems and user feedback:
| Problem | User Feedback |
|---|---|
| Oil leaks | Common, especially in older models; regular checks recommended. |
| Infotainment glitches | Frustrating but often resolved with software updates. |
