Sonata I45 (LF 2015+) :: Airbag Warning Light Comes On Intermittently
The airbag warning light came on last week and stayed on for my hour commute home. Later on that same evening, I took the car out again, and the light was off. Stayed off for about 3 or 4 days and now comes on intermittently. I called the dealership today to try and set something up, and they said if if it's coming on intermittently, check under the seat for anything obstructing the airbag sensor and whatnot. I looked today and found nothing (I keep my car extremely clean) but none the less found no issue. The service advisor from the dealership also said that I need not bring it in unless the light stays on all the time. But I'm insisting on bringing it in in the next few days. I'm just concerned that either the airbags may inflate without cause, or may not inflate in the event of an accident. Should I wait until the light stays on? Going into the service department at my local dealer is always at least a 2 hour ordeal and they don't issue loaner vehicles unless they absolutely have to. I just don't want to waste my time.

I was driving this morning after doing a brake job (nothing to do with the problem, just anger coming out) made it about 10 kms and noticed when i took my foot off the accelerator, the heater fan powered down a bit, and back up when I gave it gas...noticed a knocking sound from the engine...pulled into a gas station and put it in park. After a hard time idling, it cut out. I started it again and the idle was not good at all. kept cutting out. Got it going and made it home with the same sort of power issue. Tried to start it a couple times and same issue with the idle. Sputtering quite a bit and noticed quite a bit of exhaust coming out. When I backed it out of the garage, I noticed a small puddle of oil.

2016 Hyundai Sonata SE
6000 miles, 3 months old
2.4 GDI engine, auto trans
Variable-Displacement Compressor (no clutch, anyway, so that's what I'm assuming)
Is it OKAY to drive the car without refrigerant to circulate lubricating oil, or am I going to be looking at a new compressor in a few years?
A week ago, a grasshopper put a hole in the condenser. Yes, a friggen BUG, complete with bug guts and wings stuck around the tiny dent and pinhole. I'm arguing with Hyundai over the warranty coverage, they say "outside forces" and I'm saying "defective part or crappy engineering"...
The dealer's service writer said there would be no problem driving the car while we wait for parts, as long as we didn't turn the AC on. Okay, it's not summer anymore, but doesn't the compressor want to be on in DEFROST setting? Supposedly the system won't try and turn on the compressor if it's low on charge, but...being a variable displacement compressor with no clutch...
Sonata I45 (LF 2015+) :: Parking Brake Light Came On While Driving
My parking brake light came on while driving. The car would coast at a low speed OK, so I think the brake was not on.
This happened in Yellowstone National Park at altitudes above 7,600 ft. and happened 4,000 miles ago and hasn't happened since. Taking the car in for an oil change today and I am going to ask about it.

I have a 2016 Sonata Sport. My logos on my radio will be there when I start the car and when I start to drive they disappear. I have tried to reset my radio using the little reset button but nothing seems to fix the problem permanently.
View 3 RepliesSonata I45 (LF 2015+) :: Instrument Cluster Restarted While Driving
This happened around 3pm yesterday on Limited 2.0T.
I had Hyundai Navigation going to see what the 3D view looked like (8" display on map fullscreen), along with my iPod Classic playing music. On the instrument cluster, I started cycling quickly through the tabs on the center LCD starting from the MPG/speed page to the navigation page (via the menu button on the steering wheel). I overshot it and cycled through again.
I was doing this very quickly when the whole instrument cluster restarted as if the engine was off and turned back on. The LCD and numbers on speedo and tach completely went out, the needles on speedo and tach went to zero and returned (while cluster was still off), and the cluster did a system check, with all icons displaying for a second then turning off and the System Check screen displaying on center LCD.
In addition, I previously had AUTO HOLD on and when the instrument cluster restarted, AUTO HOLD was displayed in red and could not be turned off or activated (car would not auto hold) and the traction control icon (I believe) stayed on. The main 8" display was unaffected when all this happened.
I was able to turn the car off and back on later and everything seemed fine after. It freaked me out quite a bit, especially when all this happened while I was driving.
Sonata I45 (LF 2015+) :: Collision Warning Signal Go Off When Driving Randomly
On my limited sometimes when I am driving randomly and a car is in front of me but not far up my collision warning signal goes off.
It's only happened about 4-5 times and I am not sure what sets it off or how it even really works?
Sonata I45 (LF 2015+) :: Squeaky Sunroof While Driving On Bumpy Roads
The sunroof seems to squeak a lot while driving on bumpy/ uneven roads.
Before I didn't know where the squeaking sound was coming from, I assumed it was from the doors. But when I opened up the sunroof the squeaks went away and when I closed it the squeaks came back. The sound is so irritating sometimes that I am forced to drive with the sunroof open.
Sonata I45 (LF 2015+) :: Collision Warning Popping Up On Dash While Driving
Have any of you noticed the collision warning popping up on the dash while driving? The first couple of times I missed what was popping up since I was busy driving and not getting into a collision. The last time, however, I did notice. A car was making a right turn up ahead and had almost stopped in the lane..

As I am driving the steering wheel will randomly lock for about 2 seconds. It has happened while changing lanes on the highway, also happening while making turns in intersections. Took it in to the dealer, all they did was clear the code and give it back to me. I have notified Hyundai Customer Care and they are supposed to contact me but right now the car is unsafe to drive.

I've been noticing an oil burning smell after driving recently, it's been going on for a few days now. My oil level is good, I have 8,500 miles on the car. Today I finally had a chance to look under the hood for any visible leaks, and I noticed some oil stains on what I think is the valve cover gasket.

Sonata I45 (LF 2015+) :: Engine Just Sputtered And Shut Off
I was driving and got off the freeway exit ramp and while I was waiting to make a left turn, the car all of a sudden started sputtering (RPM's were low up and down on idle) and eventually died while waiting to make a left turn.
Turned on the engine again.. same sputtering occurred and had to gas it so it wouldn't turn off.. Finally got to the side of the road.. turned the car off checked the oil.. no issues.. engine temperature was fine.. no check engine light.
After about 30 min later, turned the car on and it seemed to be normal again so I carefully drove to the dealer and encountered no issues. Took the car to the dealer and they couldn't find anything.
I drive a 2015 Hyundai Sonata Limited with about 19k miles now.
Sonata I45 (LF 2015+) :: Engine Shudder At 108km/h Upon Accelerating
Well, my MIL came on, and hasn't left (yes, my gas cap was tightened). My bigger concern is that when I'm on the highway, if I have to slow down for traffic, upon accelerating again, when I hit 108km/h, the car does a crazy death shudder, and slows down...I have to release the pedal, let it slow to around 95, and then I can accelerate again. I'm gunna wait and see if the light goes off after a couple of days, but this is worrying.
View 25 RepliesSonata I45 (LF 2015+) :: Long Beep After Shutting Engine Off
Recently, my car (2015 Sonata GLS) has been making a long beep after shutting off the engine, similar to the beep you get if you exit the car and leave the smart key inside. The beep is outside the car, not inside. The beep happens immediately upon hitting the ignition button, before I even have a chance to open the door. There is no indication of anything on the LCD screen.
This is really annoying, especially when it happens in my driveway late at night because I'm sure the neighbors can hear that 5 second-long beep. What it means?
Sonata I45 (LF 2015+) :: Transmission Would Not Move Into Park When Turning Engine Off
I pulled into my garage yesterday and when I tried to move the transmission into Park it would not move. I tried turning the engine off and nothing would allow the transmission selector to move. I thought I would have to push something into the transmission lock slot but the only thing I had that was close to being able to fit into the small slot was the key in the FOB but it would not fit. By pure chance I happen to push on the transmission selector to the right and it moved over and then I was able to push it forward into Park. I must have pushed the selector into the sport mode when I entered the garage.
View 5 RepliesSonata I45 (LF 2015+) :: Engine Vibrate And Sound Strained While Cruising
Eco model (1.6T/DCT). driven 17k miles.
My biggest concerns seem to be the DCT transmission. It's....rough to say the least. It jerks and makes terrible noises in parking lots, which can be quite embarrassing if someone else is in the car. Just today, someone said "is your car okay?" I understand that DCT's are different, but I have driven this car since brand new, and it was never this bad.
The car also seems to shift to a gear that is too high for the speed, making the engine vibrate and sound strained while cruising. This problem occurs around 1500 RPM with the gas pedal pressed and just driving along. I can easily reproduce the issue by putting the car in manual mode, selecting the highest gear possible and then trying to accelerate without hitting the kick-down on the accelerator.
I use synthetic oil from the dealer, changed the air filter already, did the fuel injector cleaner additive and also use ethanol free gas.
Sonata I45 (LF 2015+) :: Engine Lost Almost All Power When Pushed The Accelerator At 30 MPH
I pushed the accelerator all the way to the floor at 30 MPH and the engine lost almost all power? As soon as I let up to about 9/10 throttle everything reverted to normal. Took it to the dealer and it showed no codes. The Tech and I took it for a road test and it did it only one more time. He said to keep an eye on it but was baffled. I tested it later in the sport drive mode and it would bog down every time if pushed hard to floor at about 30mph.
My best guess is that I got some bad regular low octane gasoline and the ECM is sensing a knock and retarding the timing or cutting off fuel flow similar to over revving condition. I will fill it up with 93 Octane Premium next time I get fuel and se what happens. Usually runs fine on 87 Octane but most of the time I don't floorboard the accelerator pedal. As I said at 9/10 throttle it runs fine.
Sonata I45 (LF 2015+) :: Grumbling Noise From Engine When Accelerating Uphill
I have a 2015 Sonata SE 2.4L with 15k miles. Sometimes when accelerating, and almost always when accelerating uphill, the vehicle makes a noise that I can best describe as sounding like a grumbling or rattle from the engine. It almost has a "diesel engine" sound to it. I have noticed this going back to when the vehicle was brand new, but I have recently noticed it more.
