Latches, locks and linkages: “On Mercedes GL350, the trunk/ hatch door will not open from outside. It just stopped working. Therefore, I tried to open it from inside, but there is no manual latch inside to open the trunk/ hatch door. It is a safety issue. The dealer, Mercedes Benz of Richmond, 8225 West Broad Street, charged $235 to open the hatch door. The dealership billed total $1322.48 (after 10% discount $1219.66) to replace the latch and its motor. Kindly help the GL350 owner to have latch installed inside open the door in case of emergency.”
