Consumer Reviews for the INFINITIÂ QX50
Read recent reviews for the INFINITIÂ QX50
Great car with a couple problems
S Scranton, 11/01/2015
2015 INFINITI QX50 4dr SUV AWD (3.7L 6cyl 7A)
I have owned and loved my previous G35 Infiniti for several years and many other vehicles that were high and medium end vehicles. This is a great car but it has a couple engineering flaws that even Infiniti acknowledges. The first and most important is the outside temperature reporting. It's always wrong! Infiniti knows that the problem in placement of the temperature sensor next to … the radiator. So, why not fix it? The outside temperature then drives the automatic temperature control in the vehicle. Another problem is blind side visibility. It's addressed with an add-on package at the factory, but cannot be added once you take delivery. Not to be a Scrooge, this vehicle deserves justice for the facile buggy it is. Fast, fun to drive, responsive and it has substantial room for luggage, garden equipment/supplies and dog cage used for our trips to the park. I'd buy it again, but engineering needs fine tuning, as alluded to above.
Comment after 1 year: The new buyer comment is still on the money. Great car with above caveats.
