“We bought the vehicle on march 8th and it went in the first time on march 24th for a water leak coming from the sunroof housing. The supposedly resealed the sunroof housing and it went back in for the second time on june 23rd. Same water leak in the exact place again. Now they're saying that the sunroof glass is warped and that's why the seal isn't holding. 2 times in slightly less than 3 months within 6000 miles.”
