Key Takeaways for your Infiniti

Here are the 4 key takeaways summarizing the common problems detailed below for Infiniti

Engine & Timing

Infiniti models commonly face engine problems, crankshaft angle sensor failure, and timing chain wear, especially in VQ-series engines after 100,000 km. Symptoms include oil consumption, stalling, and rattling noises. Timely diagnostics, oil changes, and timing chain service are crucial to avoid major engine damage.

Transmission & Drivability

Infiniti transmission issues—such as jerky shifting, delayed engagement, and steering wheel lock failure—can reduce drivability. These problems often occur in G37, QX60, and JX35 models after 100,000 km. Transmission fluid service and software updates improve performance and prevent sudden immobilization or gearbox failure.

Brakes, Tires & Lighting

Common Infiniti wear-related issues include premature brake wear, uneven tire wear, and brake light malfunctions. These faults typically emerge before 80,000 km and affect safety and handling. Routine inspections, alignments, and bulb replacements help reduce costs, extend component life, and improve road visibility.

Fuel & Electrical

Infiniti owners often report fuel pump failure and electrical issues, leading to starting problems, hesitation, or dashboard warnings. These occur around 100,000 km in models like the QX60 and G35. Early fuel system diagnostics and electronic control module servicing help avoid breakdowns and maintain reliability.

Top 10 Infiniti Problems

A breakdown of the top 10 common repair and maintenance problems in Infiniti cars.

Electrical problems are common in Infiniti models like the G35, QX60, and Q50, including intermittent power loss, dashboard glitches, and sensor failures. These issues often result from faulty wiring harnesses, worn BCMs (Body Control Modules), or battery drain after 80,000–120,000 km. Symptoms include non-working lights, audio malfunctions, and interior system failure. Diagnosing Infiniti’s complex electronics requires advanced scanning tools. Regular battery checks, module software updates, and fuse inspections help maintain system integrity and avoid costly electrical system repairs in luxury Infiniti vehicles.

Top 5 Most Frequently Asked Questions About Infiniti Vehicles

Answers to the most common Infiniti problems, maintenance questions, and repair concerns.

The most common problem in Infiniti vehicles—especially the G35, QX60, and M35—is timing chain and engine sensor failure, particularly involving the crankshaft angle sensor. These issues often occur after 100,000 km, leading to check engine lights, stalling, or rough idling. Infiniti’s VQ-series engines, while performance-oriented, are prone to timing chain stretch if not serviced. Addressing sensor errors early, maintaining oil quality, and inspecting timing components can prevent serious engine damage and keep Infiniti’s drivetrain running smoothly for the long term.
