- 2019 TourX Essence, Ebony Twilight Metallic
Front differential was replaced. The day after I bought my CPO TourX with 11,000 miles on it, I put it up on my lift, and spotted a drop of trans fluid by the right front axle. Dealer found a hairline crack in the differential. No diff could be located in their parts system for 10 days, then GM went on strike. 2 1/2 months later, the dealer had a new differential installed. I was overjoyed. Drove my nearly repaired car for all of 100 feet out of the dealer's lot, heard a terrible sound under my car, and pulled over. The propeller shaft had fallen out from the new front diff, and immediately bent when it hit the ground. New driveshaft installed a few days later. All has been fine since then. Note that it is a 2-piece driveshaft, so the forward portion was replaced. I now have 16,400 miles on the odometer.
