I bought my wife a 2019 Atlas V6 To replace a Porsche Cayenne. Love this car, never liked the Porsche. Only issue. On initial acceleration there is a grinding noise up to about 2,500 RPM. It is most noticeable when starting on a hill. I know the car has electric cooling fan but it sounds like a bad fan clutch on an old car. Dealer said it is normal. Drove another v6 and it was not there. Possibly a bearing going bad in the turbo?
