Edge is back in the dealer service again for a recurring problem. It first appeared when driving at speed near 70-80 mph. The car will vibrate when turning the wheel to the left as in changing lanes. It actually feels like you are riding on a rumble strip. The vibration seems to be coming from the passenger side. Took it to the dealer and they replaced the tire on the passenger side. The vibration occurred a second time which was after the tire replacement, and it was at the same speed 70-80 mph but it not only was vibrating while turning the steering wheel to the left it was also happening while going straight. The vibration was more pronounced this time. The vibration lessened when taking your foot off the gas but increased when accelerating. In both instances, the car was driven at highway speeds to a destination, parked then driven back on the highway again. The vibration only occurred when the car was driven on the return trip. This is not the lane sensing which was off and the vibration is not coming from the steering wheel as it does with the sensor. Any ideas about what it could be? The dealer is having difficulting figuring it out.
