2011 GL 450 Accelerator Feels Stiff
Hi,
I'm new to the Mercedes. I just purchased a 2011 GL 450 and it's a beauty with less than 27K miles on it. BUT......it's a 2011. I've had to replace parts on the suspension and now I've noticed that the accelerator feels like there is a rock underneath it when I try to accelerate. It will accelerate when I push down really hard, but it doesn't seem normal. It also has a sound coming out of the tail pipes on the right side that, the only way I can describe it, sounds like helicopter blades hitting the air. The car idles fine and "seems" to be okay in terms of the engine. But, I have no clue what the sound is and why the accelerator is so stiff.
Thanks for your help.

Welcome. This sub forum is for newer model year GLEs. You should repost here since your model is an older GL x164:
