| Engine And Engine Cooling problems |
The twin turbo failure is a known issue with Infiniti. I took my vehicle to the dealership and it was diagnosed with having a passenger side turbo failure. I have 145k miles on my vehicle. It is outside of the warranty period and very expensive to repair. Infiniti knows there is a problem regarding turbo failure in the Infiniti Q50 and the consumer is forced to deal with expensive repairs $7k for one turbo per the dealership. Had I been made aware of there being a problem, I would not have purchased an Infiniti.
Shortly after purchasing the vehicle, I began experiencing serious performance issues. While driving, the vehicle suddenly lost power, would not accelerate properly, and warning lights appeared on the dashboard. The vehicle eventually shut off while in operation. The vehicle was inspected by a dealership, which initially stated there were no issues. However, the problem continued and worsened. The vehicle was then inspected by an authorized Infiniti dealership, where technicians identified a consistent knocking noise coming from the engine. The dealership indicated that the noise is consistent with internal engine damage and recommended further inspection and likely engine replacement. The issue developed very shortly after purchase, and there were no prior indications that the vehicle had been damaged or misused. The sudden loss of power and engine failure created a potential safety hazard, especially while driving in traffic, as the vehicle was unable to accelerate and could have led to a dangerous situation. The vehicle is currently available for inspection, and the issue has been confirmed by a certified dealership. The cause of the failure is currently under further evaluation.

While driving, my vehicle suddenly shut off without warning. After restarting, the vehicle would not accelerate over 40 miles per hour. I had the vehicle inspected by the dealership, and they informed me that the engine oil filter contained metal debris. The dealership explained that the presence of metallic particles in the filter could indicate internal engine wear or damage, and they recommended a full engine replacement at a cost of approximately $20,000. At this time, I have not been shown the filter or the debris, but I was advised that this condition may require further diagnosis and possible engine repair or replacement.
