Sonata I45 (LF 2015+) :: Driving Car With No Refrigerant In AC
Nov 10, 2016
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...

if I start my car and leave it in park and turn the air on max, on the 1st or 2nd fan setting, I usually get no cold air, its just normal temperature. if I begin to drive for a bit the air turns cold, then if I stop and park, the air usually stays cool sometimes.
however, last week we had a heatwave here in SoCal and it was around 100 or so, and my car was outside for a while. I started it up and the air was not blowing cold for quite some time, I had to drive for a while to get it going.
I drive mostly on the highway and my A/C works fine but I noticed hiccups like these here and there and want to know if its something I should look into before it gets worse

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.

On my way home tonight, I received several messages on the screen that a battery drain is happening and I should start the car. However, it WAS running!

Had driven about 3 miles, engine warmed up. Stopped at the store for about 5 minutes and cut motor off. I started engine, put in drive and after about 20 ft., the motor cut off. Luckily I was in a parking lot and coasted to a stop. Started up again and everything seemed ok. One thing I did notice was after the cutoff, all dash icons, (oil, brake, engine, etc) were on. I especially noticed the key icon, indicating key was not in car, was on. What happened? Is this something that I should have the dealer look at? I doubt they could ever replicate 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.

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.

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?

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.

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.

I've got a friend who had a leak repaired on his '98 Chevy S-10 pickup but didn't have the system recharged. I have a vacuum pump and gauges and told him I would pull a vacuum and recharge it for him, but he doesn't know the refrigerant capacity and I don't have manuals on this model. What is the capacity? I'm figuring 1.5-2 lbs but would like to know exactly what's recommended by GM before starting on it so I can tell him how much refrigerant to buy.

My AC is slowing down and needed diagnostics. Fan system is fine. So I hooked up my manifold guage set from HF and got 90 on both high and low static, and 35/175 under load. Temp was 83 Fahrenheit with 36% humidity.
My diagnosis - refrigerant low. (i.e. low/low)
So what kind of quantity can I assume I'm down? Do these german ac run on the high side? I'm going to pour in the PAG 46 myself through the yellow line, and that runs roughly 5 to 1 to the refrigerant. NO SEALANT. Just a 12 ounce can of 134a and 3 ounces of PAG 46.
Just to verify - it is PAG 46 for the 2004 Jetta 2.0 GLS?

My 01 excursion is leaking refrigerant. Added UV dye, and still can't find leak. It takes about 5-7 days to lose charge.

I'm replacing the compressor and accumulator on my Explorer. I'm having the shop evacuate the system, but they want to fill it with R134, so I'd rather use the cans if I can find out how many ounces it needs. I'm seeing conflicting information on the refrigerant capacity for the 94. Is there an authoritative source, like the factory service manual?

I've been driving this Sonata 2015 Limited and while going very light on the pedal in eco mode it is barely hitting 18 to 20mpg. I find that very odd, and presume something is either calculating wrong or the car has an issue.
2015 limited
Eco Mode
2.4l engine
City driving but very soft on the pedal.

Seeing issues with A/C not getting cold? I thought it felt a little warmer than it should, and then my wife got in my car and instantly called it out, and now it is pretty close to room temp. air....Could it be low pressure in the lines? Or the fluid itself (freeon...? =s) ?

Here is a quick video I shot the other day. This is the second time this has happened where the Cruise just won't engage. There is no error showing other than the message that comes up when I try to engage the cruise (Cruise on, press switch to the bottom to set.)
I've seen this same error if I try to Resume speed without having previously set the speed, but this was not the Resume being selected, but the Set.

2002 1500 4WD 126K miles. A/C not working, compressor does not engage when A/C is switched on. Is there an interlock if the refrigerant level is too low to keep the compressor from engaging? Original owner, A/C has never been recharged. Is recharging my best first step.

2004 Santa Fe, 130k, auto, 2.4L engine, FWD
Bought this car during the winter and didn't need to use the air conditioning until recently, which as you could guess blows warm. Filled up with R134a and all was good for a few days, nice and cold.
Then after about 5 days it was blowing warm again. About half of the refrigerant had leaked out. Looked like the schrader valve/valve core was leaking on the low side so pulled it out and put in a new one. Filled up with new refrigerant, same thing... lasted a few days and now warm air again.
Is there a common spot for leaks on this model? I know I need to get a can of r134 with dye in it to try and find the leak, but I heard it can be the evap core which you can't see openly. Do the hoses normally leak? should I replace all the O-rings, etc?
