Infiniti Engine Diagnostics and Repair

Familiar With the VQ V6 and Infiniti's Shared Drivetrain Systems.

Infiniti is Nissan’s luxury division, and its cars are built on Nissan’s engines and transmissions, which is where both their strengths and their weak points come from. Around Clarksville, that shared engineering means an Infiniti’s issues line up closely with the Nissan patterns we already know, so they’re familiar rather than exotic.

The VQ V6 that powers much of the lineup is a strong engine with a known timing chain tensioner wear pattern, and the QX60 shares the continuously variable transmission found in Nissan’s larger models. Add the oil use some of these V6s show and the front brake wear the sport sedans are noted for, and most of what an Infiniti needs is a known quantity.

Infiniti Problems We Diagnose and Repair

Known Repair Concerns by Model.

Issue
Timing chain tensioner rattle on the VQ V6
Models
G35, G37, Q50, and Q60 with the VQ engine
A rattle on startup from the front of the engine often points to a worn timing chain tensioner or guides on the VQ V6. It's more common on the higher-mileage examples, and it's worth confirming with a listen and a scan before it worsens.
Issue
CVT problems on the crossover
Models
QX60 and the earlier JX35
These share the continuously variable transmission used in Nissan's larger models, which is prone to shuddering, whining, and overheating. Some of it is serviceable and some is a failing unit, so a proper diagnosis determines the path rather than jumping to a replacement.
Issue
Oil consumption on the V6
Models
Higher-mileage G37 and related VQ models
The VQ V6 can use more oil than expected as it ages. The concern is running low between changes, so we measure the actual consumption and decide whether to monitor it or look deeper based on what we find.
Issue
Rapid front brake wear
Models
G35 and G37 sport sedans
These are noted for going through front brake pads and rotors faster than many cars, a trait of their setup rather than a defect. Owners often notice the wear sooner than expected, and staying ahead of it protects the rotors.

A Shop That Knows the Nissan Platform

We Diagnose the Drivetrain Before Recommending Major Repairs.

Because an Infiniti shares its engines and transmissions with Nissan, working on one means knowing that driveline: the VQ timing chains, the CVT in the crossover, and the V6 oil use. We diagnose a CVT complaint before recommending a replacement, since some of it is serviceable, and we handle the luxury features on top. You get accurate service without the dealer’s rate for the privilege of the badge.
