Humming noise on a 2011 Cadillac SRX 2wd performance


Asked by Rick May 06, 2018 at 03:38 PM about the 2011 Cadillac SRX Performance FWD

Question type: Maintenance & Repair

I have a 2011 Cadillac SRX 2wd sport
with 84,000 miles on it. It makes a
humming noise while driving it. The
noise gets faster and slower depending
on the speed. It sounds like big truck
tires going down the road. There us no
where or grooves in the rotors.

Maybe just tire noise. Tires do tend to get noisier as they wear.

Did any of you ever find out what this was? My 2012 SRX is doing the same thing.

You have a wheel bearing that needs doubt....when driving if you turn the wheel sharply to the right or left you’ll notice sound’s the bearing opposite of the direction you turned the wheels...I think...but you definitely have a bearing needing replacing...proabably about $500 repair...good luck...mine was under extended warranty I purchased....

any one figuer this out yet? Definitely not the wheel bearing change toe in noise changes


I think it’s in the 4 wheel drive. Some trucks I drive sound like that when 4 wheel drive is engaged. My moms caddy 2009 cts4 is making the sound now. Low or deep sound that goes with the speed of the car ! ?

It turned out to be the bearing needing to be rid of noise completely...been driving it for about a year since and car is like cotton on ice

I hope you are right because i know exactly what you are talking about, mine just started doing it a week ago sound like rubber rubbing plastic and faster you go the faster it sounds. at around 10 to 30 mph you dont hear it as much. At 35 40 it starts i thought my tire was rubbing on the firewall at first

2012 SRX exactly the same noise above 10MPH, changed out the right rear wheel bearing no difference. put the right rear bearing on the right front. no difference. checked the left rear bearing, that seemed fine so i left it in place. the driverside wheel bearing is stuck in the axle and i was not able to get it off yet. i dont have any play in any of the bearings and left to right turns dont make any difference on the noise. no clunking or other noises. i will have to get the drivers side bearing replaced to see if that fixes it.


check rear end fluid first before changing the wheel bearings

Same problem on my 2015 SRX - Replaced all bearings. Auto shop says everything looks good, but it might be stuck in eco mode. Sigh


2014 SRX I just got with 100K on it. Noticed the noise, mechanic checked the axles and bearing hubs. Previous owner change axles and my guy changed the right front bearing hub. Noise persists! Its not the engine or anything related to RPM. Put it in N while at 60 no difference, rev engine son difference, the whining is directly correlated with speed. I do notice a relationship with being under power and coasting that alters the volume of the noise. So I am like the rest of the bloggers. Could it be the transfer case

just had the same problem on my 2013 srx. Changed all 4 hubs, brakes, and tires. Still same drone noise. Ended up being a software update from the dealer for the sound system. (Wierd I know) cost is $100 with warranty or $155 without warranty.

Well my persistent noise turned out to be the transmission. Found a used one with 50,000 for $500 and $1,000 install. Will have it installed next week.


My Cadillac srx 2012 makes a whistling noise only when I get up to 40 miles an hour. When I slow back down the noise goes away. When I slow down and I get to about 19 miles an hour my transmission shift hard going down to first gear. I never have a problem going back up it shifts fine. What could those issues be?
