RPM Fluctuation

[rannel.bradley]

I have a 2011 SLS AWD with just under a 100k miles.

I’ve been having this problem for over a month where my rpms fluctuate around where they should. It does at constant speed with and without cruise control engaged and whether it is in automatic or manual mode.

There is no CEL. There isn’t a whine or any other apparent issues.

I was trying to upload a video but it’s not working. Here is a video of another car doing the exact same thing for reference.





Any ideas? Anyone else ever dealt with something like this?

Try cleaning your throttle body and throttle position sensor. Some seem to think this might be the culprit.
If that doesn't help, take it into a Suzuki service location before your warranty is done for at 100K miles.

Video: that's EXACTLY how my mother in law drives. Makes me car sick.
Does the car actually accelerate bit and then slow down?

Not at all. The speed remains the same and it doesn’t sound like it’s accelerating or decelerating either. It’s really unnoticeable other than the meter.

Did you find out the cause? I’m having the same problem at highway speeds! Just started happening at 88k miles. New transmission fluid at 80k.
