The 2018 BMW 740i is a luxury sedan that combines performance with comfort, but how does it hold up in the reliability department? As an auto owner, you want to know if this car can stand the test of time without draining your wallet on repairs. Let’s break down the key components and see how they fare.
Engine Performance
The 740i is powered by a 3.0-liter inline-six engine that delivers a solid 320 horsepower. This engine is known for its smooth operation and impressive acceleration. However, some owners have reported issues with oil leaks and coolant system failures. Regular maintenance is crucial to keep this engine running optimally. If you’re diligent about oil changes and monitoring fluid levels, you can mitigate some of these potential problems.
Transmission Reliability
The 740i features an 8-speed automatic transmission that shifts seamlessly under normal driving conditions. While it generally receives high marks for reliability, there have been isolated reports of transmission issues, particularly related to software glitches that can cause rough shifting. Keeping your software updated at the dealership can help avoid these headaches.
Suspension and Handling
The suspension system in the 740i is designed for a plush ride, utilizing air suspension for added comfort. However, air suspension systems can be prone to failure, leading to costly repairs. Owners should be aware of potential issues with the air compressor and air springs, which can wear out over time. Regular inspections can help catch these problems early.
Electrical Systems
The 740i is packed with technology, which can be a double-edged sword. While features like adaptive cruise control and advanced infotainment systems enhance the driving experience, they can also lead to electrical issues. Problems with the battery, alternator, and various sensors have been reported. Keeping an eye on warning lights and addressing them promptly can save you from bigger issues down the road.
Braking System
The braking system on the 740i is robust, featuring large disc brakes that provide excellent stopping power. However, some owners have noted premature wear on brake pads and rotors, especially if the vehicle is driven aggressively. Regular brake inspections and timely replacements are essential to ensure safety and performance.
