A rattle (vibration) noise when car is idling and when you accelerate.
When the car is put in reverse or drive the rattle from a heat shield or something else becomes very loud
my local independent repair shop simply removed the heat shield.
My vehicle has the same problem. When taken to a mechanic, they can't find the problem.
Exhaust heat shiel rusted through on clamp closer to engine. Rattles almost constantly
Shield at exhaust manifold rattles when cold.
I too had the rattle noise from a heat shield. The dealer corrected the problem.
rattles on cold start, but after it worms up, it stops.
There is a rattle noise when I drive and it's coming from the left side. It also does it when I move the gears
Strong noise when accelarate
heat shield making a tinny noise on acceleration taking it to dealer hope it is covered under 5/yr 60k
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.
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???
