A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
The cruise control does not work going down a hill. It works on a level road. It works going up a hill. I set it at say 50 MPH on us route 30, boswell, pa going down a hill and without applying the brakes the vehicle would be going 60 MPH at the bottom of the hill. This is dangerous. Dealer told me not to use the cruise control going down a hill!
Went to start car after it was sitting over night (and temperature had dropped) and it would not start, requiring a jump. Nothing was left on overnight. Car required jump start two more times until I was able to take to dealer. I was told it was a defective battery and battery was exchanged. Three weeks later, after stopping for gas at 5am on way to work, car would not start again. Again nothing has been left on. Car is currently dead in my driveway. It is a 2019!
On three occasions the battery in my 2019 qx80 has died for no apparent reason. The car is a 2019 and the battery died 8 months, 10 months and now 13 months after purchasing it brand new. Each time the car has driven fine in the morning on my way to work but when I tried to turn it on to head home it didn't start. I was initially told it was a bad battery and then told it was an alternator issue. I have two young children and am now scared to drive them in our family vehicle out of fear of being stranded again.
I was driving down the road, only vehicle on the highway and it was a clear, hot, and sunny day. I heard a loud noise like a gunshot and then could hear the sound of air like riding with the window down. I looked around inside my car and didn't see anything so I pulled the shade a little from the sunroof and it was shattered.
