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…
Ongoing failure to start, multiple battery replacements in less than 2 years. Purchased a warranty and of course the vehicle will not replicate its failure to start when it is at the dealership for the warranty claims adjustor to review. Car has had to be towed to the dealership with no resolution even after being there multiple times. Dashlights have gone dim - issues with multiple lights coming…
I have had this vehicle for a little over a year and since april, I have been stranded in different places. The reason is because I would go to get in my car and the battery was completely dead. The first time this happened, the dealership said it was a recall issue that they claimed to fix. This happened again 3 months later, at night with my baby at the grocery store. I went to get into my…
Something keeps killing my battery. There’s no lights that come on to indicate a problem. I’ve been stranded twice at work and now today, I get ready to leave and the battery is dead again!! I’ve gotten a new battery three times in a year’s time. I’ve searched for a recall because I see where others are having the same problem, but apparently there’s not one. Hopefully, the dealership will have…
My wife is in quarantine with our daughter in oregon. Drives the qx80 every 2 or 3 days, to go to the store for food. Qx80 started up just fine, drove it to the store and parked it. 35 minutes later, came out of the store with perishable groceries, the battery was too weak to start it. Had to be jump started. Seeing that others are having the same issue. Called the dealership about the…
I have been stranded numerous times with this vehicle. Some battery gremlin or electrical gremlin. Brought to the shop and they said there was a recall that was fixed. I went to the store 2 days later , came out with $400 worth of groceries and go to start my truck and nothing . Blinking flashing electric glitching . It took 15 minutes of just trying to jump it off!!! Annoying and dangerous !!…
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…
