The vehicle entered dealer custody in 08/2025 after a dead battery / lockout repair event and was returned by the dealer on 01/08/2026 after months in dealer custody for repair work. Before entering dealer custody, the vehicle was drivable. The dealer documented a completed road test and inspection, but the vehicle was returned in unsafe and inoperable condition. Immediately after dealer return, on the drive home, the vehicle shook violently and emitted a strong burning smell, requiring multiple stops. The condition was later duplicated with dealer personnel during a road test. Despite that, the dealer refused meaningful diagnostic work and later returned the vehicle by flatbed. Since that return, the front brakes appear seized/engaged. If the vehicle is placed in drive, it remains stationary. If throttle is applied, it moves only slightly while squealing as though the brakes are locked on. The vehicle is not safely drivable and has remained inoperable since 01/08/2026. This created a safety risk because the vehicle was returned for use on public roads despite violent shaking, burning odor, and what appears to be brake seizure/drag. The symptoms were reproducible and were brought to the dealer’s attention immediately. The vehicle remains available for inspection.
My husband and I own two G55's purchased on the same day. They both started leaking fuel infrequently within two weeks of each other. You can actually see the fuel dropping to the ground and smell the gas. I filed a complaint for the other VIN as well. That complaint number is 10490150. The link to the youtube video showing the leak is in the text of the other complaint. When we have taken it in, the service department cannot detect it; they keep trying to send us home. This is incredibly dangerous.
