Service brakes
1 report
“On July 19, 2019, with 8800 miles on my 2018 Bentley Bentayga, I took it into an authorized Bentley dealer repair shop for routine service. I was advised that the brakes, front, and back were dangerously low. There was no prior warning or indication of this problem. I had the front and back brakes replaced. In September 2022 with approximately 16,000 miles on the car, I noticed a squeaking noise coming from the front end of the car. On November 14, 2022, I took it back to the same authorized Bentley Repair shop. I was advised that the front brakes were dangerously low and needed to be replaced. The service man advised me that he had customers having their brakes go bad in this car in as little as 5,000 miles without notice..”
