My Regal started vibrating badly while accelerating into left hand turns. I took it to the dealer (only 24,000+ miles on it, turn 25,000 today coming back from FL), they finally found a bulletin about a "weak" transmission mount, and ordered me a new one. I went back there 4 days later when the part came, the vibrations were worse than ever, the mount had broken!
They replaced the mount, I left the dealership (also, I recently had a rotation/balance/alignment done) and the da*n thing is still vibrating, just not as badly... anyone got ideas or had the same problem? TIA, Liz
