Vibration/rattle underneat when starting/accelerating

After we bought it 1 1/2 years ago, the dealer later said it was a simple heat shield fix, not covered under warranty and cheaper for us to do ourselves. Is that really what it is?

In the winter, when I start it, I hear the vibration/rattle for about 3-5 seconds while warming up...very loud! I don't hear it in reverse, but in shifting to drive I can hear it occasionally until fully warmed. Now that its summer and the outside temp/garage temp is 70 degrees or above, I don't hear it when I start the engine. But, when I shift to drive I'll hear it a couple of times, for 1-2 seconds, then it stops.

I had the same issue. They replaced the muffler that was cracked inside, as well as the heat shield. Problem solved.
They even showed me the pieces as they fell from the muffler.
A common problem with this vehicle and covered as long as it is within the 36 month/36,000 mile bumper to bumper deal.

I don't think its actually a problem, its just because the engine is cold, i don't think you have something to wary about.

Heat shield rattling noise engine


Go to a a large hardware store and buy 2 band clamps that will fit around the heat shields and clamp them tight. This is the manufacturers approved fix for heat shield rattle. The fix sure beats the $1000.00 for a new catalytic converter assembly. I have done this fix dozens of times over the years of my car repair career.

2010 Kia Sedona rattle in front when accelerating


As the dealer was unable to find anything, it's possible that this could be normal operation.

All modern auto engines will knock under heavy acceleration; could you be confusing engine knock with "vibration"? (The knock is by design to allow the knock sensor to determine how lean to set the computer. This can be changed by a change of gasoline to a different brand or different grade. Don't run mid grade ot hi-test for more than one tankfull if your car calls for 87 octane however.)

In that the light came on (and off), will set a code in the computer that the dealer can read. Take it back to the dealer and tell him the history. He will be able to read the error and narrow down the cause.

When the car is cooled off bang on the exhaust. It's possible you have a heat shield that is loose. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

VIBRATION


Does the rattling occur whilst you are sitting still, and run the rpms up? Does it come in at a particular rpm, and then go away? If so, the heat shield is the problem. I see this quite a bit. If you can get it to do it at a specific rpm, have someone slide under the truck and, with a large screwdriver, pry on the front pipe and the converter shields. See if the vibration changes.
