What's the most common problem on the 2005 Infiniti Q45?

No problem area has crossed our reporting threshold yet, which is a good sign for this vehicle.

What's the most expensive thing that goes wrong?

Major repair items haven't been flagged often enough on this vehicle to single one out.

How do I check if my Infiniti Q45 has open recalls?

Paste your VIN into the decoder at the top of this page. We pull live from NHTSA, so you'll see exactly which campaigns apply to your vehicle and whether the dealer has logged the fix. Recall repairs are always free regardless of mileage or warranty status.

Is an extended warranty worth it on a 2005 Infiniti Q45?

Math is straightforward: a quality service contract runs $1,800–3,500 over 3 years. With 4 complaints on file, one major failure more than pays for it. The catch is reading the contract — many providers exclude wear items and require pre-authorization, so cheaper plans aren't always better value.
