The dealer got H's approval to replace the shocks (even though my VIN was not in the range). It's been two days now and I definitely think that the metal clunking sound from the rear suspension is gone. The suspension is not as quiet as other carmakers' but I believe we're now at the 'functioning as designed' stage. Does anybody know any good sources to buy sound proofing rubber mats ?( about 1/4 - 1/2" thick )

Dealer Checked My Car's Rear Struts without me asking by rhduke00

Took my car to the dealer today for a tire rotation and balancing. The service writer told me that while they had my car up on the lifters they checked to make sure I didn't have the k thump problem. I knew I didn't but was curious as to the inspection procedure. The service writer told me all you have to do when the car is off the ground is to grab each of the rear struts and try and shake. If either one or both moves you have the problem. I asked if the problem is more likely to occur with 17" wheels. He said yes but it can also occur with 16" wheels.

Just one strut replaced???? by tuckg

As promised, here is a report to the issues submitted in my first post:
  
Had my 2007 Sonata Limited (manufacture date 8/25/06)into the dealer for two things mentioned in these forums:
1) K-thunk: Dealer said that there was a recall on the rear strut and they subsequently replaced the strut. Odd thing was that they just replaced the right strut. Sure made a big difference. When asked about the right one only, service manager said that was the only one listed. Sound familiar to anybody or did many of you get both replaced?
2) Transmission had a tough time finding a gear at around 40 MPH after slowing from a higher speed: An Adaptive re programming was done and seems to have taken care of the problem.
  
Hope this helps somebody.

From what I understand 'Adaptive Reprogramming' just means disconnecting the battery and shorting the two cables together. I was told that's all the service folk can do.

Presumably the + and - battery cables?? I am constantly amazed by the total and absolute lack of knowledge about the most basic function of an auto by many. I am not an ASE certified tech either but geez..... I once asked a co-worker what engine he had under the hood of his, by then, several year old Windstar. His answer? "I don't know I never opened it" (the hood). Don't know..don't care as long as it starts. I guess its just me!!
 Anyhow the reprogram is via a connector found under the dash. It connects a handheld diagnostic tool (Hi Scan) to the automobile electronics. There are many control modules incl. engine,transmission,ABS/traction control,stability control and probably lots more.

Um, well, how 'bout we have the conversation right here in order to benefit all of our members. It would be a good idea for you to read through the previous posts here, by the way. All of them are about this issue.
