The rear differential appears to be an issue on these vehicles. 2021-2022 models/vehicles were recalled for having an issue with the rear differential. Fortunately there was not an accident with my vehicle as I was able to determine that it shouldnat be driven. However, Iam told by the dealership that there are 155 vehicles waiting for the same repair (a rear differential replacement), and that the part to repair it is unavailable. With this information, I canat Imagine how many vehicles are still on the road with this problem. There does not appear to be a recall on older models, nor has this issue been reviewed by the mechanics that work for the company. At the very least, this issue should be reviewed during routine maintenance.
