Noticed that when drive Sonata cold without having it warmed up and you hit the accelerator even a little bit that it 'jerks' back a bit? Once the car is warmed up you don't feel it anymore.
View 11 RepliesMy problem is this: if I accelerate quickly (either flooring it or close to it), then once I reach about 55-65mph the car suddenly jerks horribly. Sometimes it's one big jerk, other times it's several small jerking movements. ECO transmission ...
It's not a problem at speeds under 50mph, but it seems once I cross that 50-55mph threshold, I can't put my foot all the way down or I will get the jerking. It will also occur if I'm going say, 60mph and need to quickly get to 75-80mph. The first time this happened, I was accelerating onto a highway and the car jerked so badly that I thought I had gotten rear-ended.
I am a proud and recent owner of a 2015 Sonata Sport 2.0T!
Car looks amazing and am very happy with it.
But lately I have been noticing lots of drone noise coming from the engine, and a really loud cold start as well. The "cold start loudness" goes away after a little bit of driving.
Was wondering if this is just the way the 2.0T sounds, or should i get it checked?
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.
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) ?
View 10 Repliesmy 2007 3.2 s80, 75 K miles, will not respond to accelerator for the first 1-2 miles after a cold start, then runs fine, no check engine light has shown. Per shop recommendation switched to 92 octane x3tanks, then replaced fuel sensor, neither solved.
View 15 RepliesI have a Limited with auto-climate. Temp is at 73 outside temp is 90. So obviously it is not just sucking in outside air. But with the AC light on I can tell the compressor is cycling as it pulls on the engine and vibrates the car more than if it is off. But with it off I am still getting cold air. How?
View 9 RepliesWhen I test drove a Sonata Eco last week, I noticed that the AC only pumped out cold air when it was on the "Max AC" setting. As soon as I moved the knob up a bit - still well in the blue territory, mind you - warmish air started coming from the vents. Basically felt like just the fan was on. Power-wise, it was set to "2".
Is this something that's common among Sonatas, or Eco's in particular? Or is this possibly just a result of the car sitting on the lot for a while, and maybe the AC needs a recharge? Living in Florida, good AC is obviously an absolute requirement, and I shouldn't need to keep it on Max all the time just to ensure cold air.
So I brought the Sonata home and she sat in the garage for 5 days as I was traveling. Then when I got back, I was so eager to take her for a drive. At this point she only had 72 miles on the Odometer. When I started her up, I thought the engine sounded rougher and louder than usual. My other car is a Turbo Diesel and that does not make this loud a clatter. After a few minutes of idling and driving, the engine quietened down quite a bit.

I have a 2006 F250 King Ranch 6.0. At approx 45-50 mph when holding accelerator steady, there is a slight jerking like the engine is missing like the old gassers used to do. What could cause this? Have a ScangaugeII and doesn't show anything out of the ordinary!
View 3 RepliesLast night I experienced a somewhat troubling event. My C had a horrendous knocking on a cold start @40 Fahrenheit or so. Shook the whole car. It lasted about 3-5 seconds, and ran perfectly afterwards, even making another cold start later on @30 without issue.
How worried should I be, and what's my recommended course of action?

Just got a DSG 2015 GTI 2-DOOR, and after 2 days of ownership, there is suddenly a shudder/vibration when I start the car in the morning.
RPMs start at around 1000, then drop to 750, and then 650, and the car starts to vibrate/shake a bit, almost like a heartbeat...
After engine oil temperature goes to ~80 Celsius, the shudder becomes much less pronounced. This all happens in "P", and doesn't happen in "D".
I have about 3400 miles on my Sonata 2.0T, and I have experienced a long crank with (puttering in between), and does not start, twice occurrence thus far. I have no warning lights, no lamps (SES) that stay on afterward, nothing at all. I have had to press the "start/stop" button again to make it stop, then let it sit for a few seconds press the button again, re-cranks, and starts this time. I know that if take to the dealer they will not find anything wrong since most concerns they have to duplicate in order to diagnose. The SES light is not on, so I know we have no fault codes to go by. Sounds as if the fuel pump is crapping out, or no spark is being generated.
View 8 RepliesJust as the title states, how do you start your vehicle if you are out and your key fob dies? Is there a method to start the vehicle without having the spare on you?
BTW, what is approximate battery life for the 2015 sonata key fob?
My car is less than 2 months old and randomly in low gears the car will jerk or lurch when shifting gears. Is this common or does this need to be looked at?

Under 1,000 miles. We both noticed it pulling to the right when on any road. The first thing that came to mind was tire pressure. I checked it. 50 PSI from the dealer/factory. We're running the Bridgestone run flats. The pressure in the door well says to set them at 35psi. The dealer was a little shocked when we brought it in that either one of their guys set it that high or someone from the factory did. The sidewall on the Bridgestone says 51psi max.
The dealer knocked down the pressures and gave us a free alignment. They said they road tested the car as well and it was good. We didn't get 2 miles away and when you let your hands off the wheel it will still pull right an entire lane in between 100-200 yards.
Is there a TSB out there on this? I'll be taking it back next week to get it looked at again. I drove a 2.5SEL when we got the tint/spoiler installed, tracked perfectly. I drove a 1.8TSI when we got the alignment done, tracked perfectly.
Also, the 1.8L was pretty impressive for a car that big. I believe it has about the same amount of power than the 2.5 but it seemed to have a lot more get up and go. Transmission however was VERY jerky and had a tough time finding the right gear.
I posted a related video in the fuel pump thread here where the high whine noise is apparent several seconds after a cold start. Now from inside the cabin, looking at the revs, the "sewing-machine-like" whine disappears above 1200 rpm.

I've driven 32k miles now, and I'm having an acceleration problem. It does not happen everyday, maybe once a month. but once I start accelerating hard to merge onto highway, it shifts down and rpm goes up but the speed remains the same.
View 7 RepliesI recently changed my intake to Takeda and I am hearing squeaking noise every time I hit on the accelerator, but only when my windows are down. So I don't know if this is from the intake or something else is wrong.
View 5 RepliesI seem to be having an issue with my air conditioning. I don't think it's an ID-10T error, but it is very peculiar.
My driver side vents blow hot or lukewarm air, however my passenger vents are ice cold. I have the 15 limited, so it does have the "dual" control, and as such I think the issue may be related to that.
Both controls are set to low, max fan, head only, and AC. The "Sync" and "Auto" buttons have no effect.
Any things I can check? I really do not want to bring it into the dealer as they treated me very poorly the last time I came in and my car was out for a month.
I have had JoeZ/PTS catback exhaust on my rc f for a few months. I recently put PPE headers on and when I rapidly accelerate in park/neutral I get a whistling sound especially when backing of the accelerator. What it is?
