I got 2019 QX50 Essential trim.
5 month: Car stopped in the middle of local intersection due to hypersensitive proximity sensor.
I’ve had drivers seat ratting problem, had it replaced, twice. I’ve had navigation system problem, had it replaced once. Map screen fizzles all the time, drivers seat belt warning goes on sometimes while I am driving, with the seat belt ON.
Now, my undercarriage cover fell off,,,

Infiniti car sucks so bad, only the sales and svc reps are great.

Sorry to hear about these multiple issues. I would be just as frustrated if not more. It sounds like you have a bad unit. I have not had any service issues in the 2+ years that I have had my 19 QX50. Maybe these can get worked out and your issues will be over going forward.

So what did you run over to cause the under carriage cover to fall off 😱

A Curb ? Parking Block ? Road Debris ?


Nissan / INFINITI assembles the post 2017 ~ new 2019 and newer QX50 in Mexico ( Cost Savings )

The old EX ~ EX35 ~ EX37 ~ QX50 which ran from 2008 to 2017 model years were assembled in Japan


Sorry to hear you're so sour on the brand - ever consider trading down the previous QX50 version ?

you can get 2016s or 2017s with low milage in the low $20K price range

You'll get a 325 HP 3.7 V6 that is based on a RWD drive platform instead fo FWD one.

You'll get a smooth shifting 7 speed ( non CVT ) transmission but by Nissan Partner Mercedes Benz.

You'll get the Japanese Builf Quality.

You'll get a bunch of Options included on all trim levels - like: Quality Leather, Sun Roof, Great Sound System, etc.

You'll get a fabulous handling car with mechanical steering and sport car like suspension.

Yeah.... definite damage to the underside there. You hit something. Most noticeable on the left side with the undercarriage rash. Kind of hard to blame Infiniti if you hit something. Document. Photograph. Get it resolved. Infiniti is one of the top luxury brands and will not leave you hanging. Contact your insurance company first.

Seems like undercarriage shield has faulty fasteners, or is is too flimsy for it's intended purpose that is has fallen off on 2 members here.

And to add insult to injury, the sensors think it is something to avoid when it flaps around when driving.

Seems like perhaps a design flaw coupled with with choosing too light of a weight of plastic that fails to properly adhere to the underside.

This part failure warrants further investigation into the commonplace of these occurrences.

The NTSB - National Transportation Safety Board - has a web site where can open what appears to be a manufacturer's flaw for possible action ~ fixes ~ Bulletins ~ and ultimately recall if it is dangerous enough of an event.

Hey - it could always be worse. My Nissan Rogue had engine carriage bushings wear out - found out later this was a known problem. Caused the front end to wander all over the place once the bushings started to go. I then found out that Nissan does not authorize bushing replacement - they only offer the entire cradle assembly.

The good news in this story - I traded my Rogue for my 2016 QX50 and never looked back. I really liked the Rogue when it held together, but quickly loved the V6 AWD of the QX50
