“While driving my car on march 26, 2020, my engine light came on. I took my car to keller's professional auto, who detected that my turbo had a crack all the way across, so I had to replace it. I only had 45,352 miles on my car. According to keller's and my research, the turbo should last for 100,000 to 150,000 miles.”
