Coming on here as a last resort because I’ve been trying to fix this noise to no avail for months (I am guessing it is coming from the suspension because it gets loud over bumps/potholes and makes no noise on the highway). At the beginning of the summer, I changed my rear shocks and shortly...

I've had an odd noise start up recently with my '13 Optima when turning sharply at speed: there is a sharp CLUNK from the rear of the vehicle, cannot tell if it's coming from the right or left side, but it sounds like it's coming from the left. The suspension has not changed/the car is not...

I have a 2012 Optima LX with the 2.4 L 4 cylinder engine. Whether the car is cold or hot, I can hear a continuous tapping/clicking noise from the top of the manifold area (I cannot pinpoint where the noise is) when the "accessory" is turned on before starting the car. The noise is not...

2016 optima My ac is making a loud flapping or helicopter sound. It sounds like I'm driving next to a motorcycle. I've noticed that if I press the recirculation button (on or off. Just press it) the noise will stop. But it comes back when I decelerate and when I accelerate. Again pressing the...

I've become a proud owner of a 2018 Kia Optima LX (My first Kia!). I love almost everything about it except I've been running into a bit of issues with road noise bothering me enough that my ears ache a little bit after driving it for 30 mins +. I've talked to the dealership and they've even...

I having an issue with my 2013 Optima 2.4 and hoping someone might have an idea what might be going on. When I tap the gas pedal there is an unusual noise that seems to come from the intake ( like burping ). The noise goes away at higher RPM but the REALLY odd thing is it will only make this...

So my 2012 Optima Hybrib had a noise coming from the rear. Took it to the dealer. In the end it was coming from front and back. Ended up replacing front left and right control arms and upper strut mounts as well as both rear stabilizer links. Throw in an alignment and we are at $2500...

Hi Guys, My Front suspension has this nasty clunking noise. Its really weird. Didn't always happen. Its when I do go over bumps but even small bumps. Almost like a reverse bottom out. Any idea? I have my car going in for routine maintenance tomorrow and will have them look at it but I...

I have a 2011 Kia Optima SX. Front brakes are 6mm. Front Rotors are 2 years old. Rear brakes and rear rotors were just replaced. The issue I am having is that when i start lightly braking at slow speeds i get a high pitch squeak. I can hold that squeak if I keep the pressure on the brake pedal...

Hi all, Having problems with my AC airflow. It started with the dash servo/clicking noises back in the fall. After trying the temp changes or vent direction changes I found the noise to be coming from when the airflow was moved from head to toe. So, I ordered the new actuator and put it in...

2012 Optima EX 2.4L GDI, automatic, 72K miles Two days in a row now I've heard a siren-like noise which appears to be coming from under the hood. The first day it happened was about an hour into my commute, and driving about 30 mph. Honestly, I thought it was an emergency evacuation siren...

The brake pedal on my ‘14 SX-T has started making a squeaking noise. I know it’s not the pads/rotors because I can feel it in the pedal and it happens when I’m park and not moving as well. Anyone have this problem and a quick fix for it?

I've had my 2015 Kia Optima EX since it was new. Have about 30K miles. Noticed today when I went out to it to go driving (a few hours after driving earlier) I heard a hissing noise. Sounded like the rear tire, but it sounded just as loud on each side of the car in the rear. I started the car...

At the 7 second mark you can hear a squeak noise that continues while driving. At the 46 second mark you can hear a creaking noise, this happens when slowing down/backing up. Sounds like it's coming from the same area (front right/front middle). Has anyone had this issue...

Hello everyone, first post here and really eager to get some help. I have been having an issue with my 2013 Optima LX for the past 2 weeks. Whenever I am driving with the AC on and accelerate in drive or reverse, I hear a humming noise coming from the engine bay. The noise is only apparent when...

Hi Everyone, I wanted to know if anyone had an issue with their 2012 Kia Optima? For the past 2 weeks I've been hearing a knocking noise in the front of my Kia. I received a recall letter from Kia as well. I am taking it in today. They have also replaced the engine about 1 year ago because...
