Infiniti Repair Frequently Asked Questions
Answers to the questions Infiniti owners ask us most
Q.How much does Infiniti repair cost compared to the dealership?
A.Our labor rates are typically 25-35% lower than the Infiniti dealership while using genuine OEM parts. For major services and turbo work, customers routinely save $200-$600. You get factory-level expertise without the dealership premium.
Q.Can you service my Infiniti under warranty?
A.Yes. Under the Magnuson-Moss Warranty Act, we can perform maintenance and many repairs without affecting your Infiniti warranty, using OEM parts and factory procedures. We provide documented service records. For warranty-covered failures, you'd return to the dealer, but routine service and out-of-warranty repairs are our specialty.
Q.My Infiniti has a CVT — should I be worried?
A.The CVT transmissions on older Infiniti models (QX30, some QX50, JX35) have a higher failure rate. We recommend more frequent fluid changes (every 30,000 miles) and diagnose shuddering, slipping, or warning lights promptly. If your CVT is failing, we offer rebuild and replacement options.
Q.Do you work on the Infiniti Q60 Red Sport and VR30DDTT engines?
A.Yes. We service the Q50 Red Sport, Q60 Red Sport, and all models with the VR30DDTT twin-turbo V6. We understand the turbo wastegate issues, the electronic wastegate actuators, and the specific service requirements of the twin-turbo powertrain.
Q.Can you fix the InTouch infotainment problems?
A.Yes. The InTouch infotainment system has known freezing and rebooting issues. We diagnose the control unit, update firmware, and in some cases can improve performance. If the unit has failed completely, we can replace it with OEM or quality refurbished units.
Q.Do you service Infiniti QX80 and large SUVs?
A.Absolutely. We service the QX80, QX60, QX50, and all Infiniti SUVs. These share platforms with Nissan (Patrol, Pathfinder, Murano) and we have extensive experience with the V8 engines, heavy-duty brakes, and the suspension systems these luxury SUVs use.
