We have a 2012 RT-SE5 semi-automatic with about 2500 miles. It developed a squeeling noise in the front left (my wife says rear) suspension not long after delivery (new). Once up to speed it goes away. My dealer says "not to worry, it's just bushings settling in and will go away after about 4,000 miles". Brakes have also developed some squeeking as well. Has anyone experienced this problem? Thanks in advance for any advice. JMT
