Infiniti FAQ
Do you service the Infiniti Q50 and QX60?
Yes. We service all Infiniti models including Q50, Q60, QX50, QX60, and QX80 for all maintenance and mechanical repairs.
What are common Infiniti CVT problems?
The CVT on QX50 is known for overheating and slipping. Regular fluid changes every 30,000–40,000 miles extend its life. If you notice hesitation or shuddering, bring it in before the issue worsens.
Why does my Infiniti rattle on cold start?
Cold start rattle on VQ35 and VQ37 engines is usually the timing chain tensioner. Diagnose promptly — a stretched chain can cause serious engine damage.
How often should I service my Infiniti QX60?
Oil every 5,000–7,500 miles with synthetic, CVT fluid every 30,000 miles, brake fluid every 2 years. Multi-point inspection included with every oil change.
