Azera HG (2011-16) :: Stiff Brake Pedal At Start Up - 3300 Miles

3300 miles in, and my brake pedal is extremely hard/stiff when I attempt to start the car. I don't have issues getting it to turn on, but it literally moves maybe 1/4 inch at most. It just randomly started doing this.

Sonata I45 (YF - 2011+) :: 2013 - Vibrating / Shaking When Slowly Release The Brake

I've recently noticed that my 2013 hyundai sonata would start vibrating/shaking, if I were to release my brakes slowly (It doesn't shake if I release it fast). I was wondering if there are any problems with that?

I do not feel any vibration in the car when I press /slam the brake. The only time I feel the car shaking is when I would slowly release the brake.

Sonata I45 (YF - 2011+) :: 2013 - Start Is Delayed A Few Seconds

I have a 2013 Sonata Limited with an odd problem. Once every 10 starts or so, I depress the start button and the car starts up but only after a few seconds' delay. I don't hear anything during those few seconds, no cranking, clicking, or other noises. Normally, the engine turns over immediately, but every now and then, there's that odd delay.

When I get into the car, the photo of the car and the word "Sonata" do show up on the center of the dashboard, so the car seems to be detecting the key OK (and I already changed the batteries in the smart keys). This delay in turning over seems not to be related to the coldness of the car (it has happened both when the car hasn't been used for a few days and when the car was used maybe 15 minutes ago). I should add that this does NOT seem to be the brake sensor issue that I had with the 2011 Sonata SE that I leased previously, as the ESC light isn't coming on.

The car is on its original battery, so I'm wondering if this indicates that the battery is weakening. Also, the car has been in a garage where there is construction work occurring with a fair amount of dust.

Sonata I45 (YF - 2011+) :: 2013 - Remote Start Won't Work

I bought my 2013 Sonata GLS back in October w/ 15k miles on it. For Christmas, I got an OEM Hyundai remote start (part # 3S056-ADU02). I took it to a local parts shop to get it installed. Turns out, I needed the jumper harness so I ordered that and they installed it today.

Now for the bad part - everything is installed, and the remote works fine. However, when I go to start the car, it stays started for 2 seconds, beeps, and cuts off and tries several times before giving up. The audio shop said to take it to the dealer to get it programmed, but I took it there and they said it would be $150 to program it. BUT they don't know if that's the problem or not. I've went through the forums and I see nothing about programming. I have found posts with problems similar to mine, but I can't find an answer. Why would it need programmed if everything else on the remote works? How can I make it stay started?

Lexus ES 2013+ :: No Power / Brake Stiff And Shift Locked In Parking Position

Mine is a 2015 ES350. I drove it normally on last Friday. Today Monday morning, the car can't be started. Other symptoms are no any lights, stiff brake, shift locked in parking position, no clank with a jump starter.

The battery connection is tight; I also tried both keys and holding it right next to the start button. It seems like the car system is shut down.

I may call AAA to tow to dealer. However, the shift is in parking mode. Is there any way I can override the shift to N?

Sonata I45 (YF - 2011+) :: 2013 - Remote Start With Keyless Ignition

2013 Sonata Limited. I requested that a remote starter be added to a vehicle with keyless ignition. They mentioned that it can't be done, as I would need an extra keyfob that would sit inside the car at all times, and that if I leave the car unlocked, anyone could get in, start it, and drive off with it. That seemed ridiculous to me, so I called another dealer to ask and got essentially the same answer, saying it was not available yet for keyless ignitions.

Sonata I45 (YF - 2011+) :: 2013 - Engine Takes A Little Bit Longer To Start

I got the 2013 sonata gls, 5700 kms.

I live in southern Ontario, in Canada and the weather is starting to drop here in the mornings and nights.

The mornings are not 0-3 degrees Celsius and at night a little bit colder.

I have notice that when I start my car in the morning it seems like the engine takes a little big longer to start. It takes no longer than 2 seconds to actually start, it just sounds like its struggling a bit more.

I notice once i drive the car for a bit, park and then start the car again it seems like it fires up quicker and without ease.

Is this due to the drop in weather? or something else at play here.

Also it seems like in the mornings when the car has been sitting for like 9 hours, after it starts the engine sounds louder than usual.

Sonata I45 (YF - 2011+) :: 2013 - Recycled Cabin Air Mode Stays Off On Start Up

I just got the Hyundai Sonata SE 2013 and it's great so far. I have a question about the recycled air button. It seems to be controlled by the internal computer for different scenarios.

My issue is that when I have the air turned on and let's so that I turn it off (set to 0) the recycled air mode disables and I start smelling the outside air coming in. So I have to manually push the button to enable recycle air to close the outside vents.

Also, when I turn off the car and later start it back up again recycled air is disabled again! How can I get the mode to stay on recycled air (or the mode it was previously on) when I start the car!?

Sonata I45 (YF - 2011+) :: Brake Pedal Hard And Car Would Not Start

I tried to turn on my car, and the brake pedal was hard and the car wouldn't start. I did a search on the forums regarding the brake light switch. I tried the 30 second hold the start button, car would not start. Radio/lights works fine so I don't think it's a battery problem. My g/f said she can see all of my brake lights turn on when I try to depress them. I'm kind of a lost. It was working fine earlier this morning.

Honda Accord :: 2014 I4 CVT - Tight Steering And Stiff Brake Boost / RPM Fluctuates On Cold Start

My 2014 Accord i4 CVT has 7000miles and it has acted a little strange ever since I pushed it to 3500rpm at Sport mode and then I maybe abruptly shifted it to Drive mode, at which point it made some whining noise shortly. But don’t get me wrong, acceleration was gentle and I don’t ever beat a car.

Since that incidence, it idles at 1500rpm upon cold start at P and fluctuates between 1000rpm and 1100rpm after it warms up a little bit (still in Park). When on stop (brake) on D, it has slight rough idle that periodically comes and goes, which gets better when the A/C is off but not completely resolves. Acceleration is sluggish and lagging, and it has some “dragging/sluggish” feel on coasting as well. When braking, it takes more effort and brake feels stiffer as if it lacks some break boost. Also, the electric power steering gets heavy/tight (I think this could be more of a sensor/input problem rather than the motor).

All these symptoms come and go together except for the fluctuating idle upon cold start, which is persistent. Gently pushing gas at 1200 rpm for, say 10 seconds, tend to “free” the tight steering wheel, and car starts to act more normally with better coasting and acceleration, and more responsive brake for a while. And problem comes back. Also, turning off the A/C seems to make the car act behave notably better but I am cautious of this point since it is known that Honda’s A/C system really takes away the engine power.

I had the dealer shop check for vacuum leak. The report says “check idle, check idle control, check for vacuum leaks ok, check or any codes, checks ok”, basically saying there is no vacuum leak. But I think it is still possible that they missed something. Dealer shops and some independent shops I visited aren’t so willing to figure out what is going on, and I basically need to ask them “check this and check that”.

Sonata I45 (YF - 2011+) :: 2013 Radio Not Working

Shortly after buying a used 2013 Sonata the radio started working intermittently then quit working at all.It's the base model radio with no navigation and no reset button. I have tried disconnecting the battery, re-seating fuses and even pulling the harnesses off of the radio and it is still not working. Before replacing the radio I want to see if i can use a battery to power it up on the bench to see if the radio is bad or if the problem is somewhere else in the car.

I tried checking the level but it has no dipstick. what should I do? my car has 54,000.
