My vehicle has the same problem. When taken to a mechanic, they can't find the problem.
Notice rattling noise.I was told a type of sheild was missing.It was repaired with some type of clamp. I paid $60 for repaires.The heat shild wasnt replaced.The rattling sound is back now.
Noise in rear. Mitsubishi dealer thought it was muffler hitting trailer hitch. Only happens when I travel for some time so I believe that heat has something to deal with it.
Repair heat shield by finding exactly where the vibration is coming from, replace heat shield or repair by welding the lose part of the heat shield.
heard the rattle. independent dealer removed it. He is calling Mits. to see if warranted. Has not been repaired yet. No idea how this will progress...betting mits won't cover it.
Loud rattle noise coming from the heat shield. More noticeable when RPM's get higher between each gear. I tried clamps and exhaust wrap, but nothing would stop the rattle!
I had a rattle that continued to get worse as I reached approximately 2400-2600 RPMs no matter what gear I was in. This was more annoying than anything else. I had the local shop rip it off the bottom and no vibrations or noise since.
rattle and bery annoying sound due to loose heat shield.
rattles on cold start, but after it worms up, it stops.
When the car is put in reverse or drive the rattle from a heat shield or something else becomes very loud
Exhaust heat sheild rattles once in a great while, but hasnt done it to much yet, butwill fix soon sometimes on those you only need to tightend something or bend something a little bit away from what its rattling against.
Same rattle. Is the heat shield needed???
Rattling Heat shield. Developed suddenly...very loud.
Rattling heat shield, came out of nowhere! checking if dealer can remove it, since I have a 100,000 mile warranty if not going to have local repair shop remove it. This is quite annoying
