Good Morning everybody!

So here's the situation. My mother has a 2014 KL, 3.2L with Active Drive 2. Owned since new, only 29000 miles on it. I put new tires on it in January (Goodyear Weatherready's) in stock size. She has recently noticed that there is a gentle knocking / clunking noise while she is a driving. It is not a very loud or forceful noise. You can only hear it with the windows up, radio and climate control off. It sounds like it increases and decreases based on speed of the vehicle. I have not been underneath it to take a look yet, but will do it this weekend.


Just curious if anyone else has had similar problems and if there is a common problem that may cause this.

 

It the knocking when she presses the accelerator pedal and then again when she lets off? Mine does this. Just another KL issue to add to my huge list.

It's more in relation to speed, faster you go, faster the noise. I took a quick look and didn't notice any problems. Although I did notice the brake rotors (all 4) are a bit scored. The brake pads must be pretty lousy.

 

So, after doing a quick look around, nothing jumped out at me, and it seems as though the noise has vanished. So, we'll see what happens.
