Sonata I45 (YF - 2011+) :: Hard Shift Roughly - Make Clunk Noise And Surge At Start Up
Aug 8, 2011
So, I took my 2011 Sonata SE in for service because I was having some transmission problems (18,000 miles). After starting the car and putting it into drive or reverse, the car would make a large clunk noise and surge forward or reverse. This happened only twice. I was also periodically getting some very hard shifts. They told me that they were getting an error showing a bad temperature sensor for the transmission fluid so they had to replace it. A lot of this started after the update. We will see if that fixes the problem.

I have a 2011 Sonata GLS with 86k miles. Sometimes, like once every 2-3 days, when I start the car, nothing appears in the box that says "P, R, N, D". The transmission also acts very strange. I often don't notice the blank box when I start the car, but immediately notice it when I put it in reverse or drive. There is an awful "clunk" from the transmission, and the car drives like I'm driving it through 6 inches of mud. I stop, put it in park, restart the car, the problem is gone.
The dealer said if it is a problem with the shift lever, that is not covered under the drivetrain warranty. I really don't have the money for the dealer to do expensive diagnostics/repair.

Just bought my new ride last week and already noticed strange clunk sound when braking. It doesn't happen all the time but seems to happen when I make full stop, like at a stop sign or stop before turning.

The past couple of weeks I have noticed my car is hard to shift out of park when I first start it after a few hours. After I get it out of park it is good until the next time I let it cool off for a little bit. It will sometime thump too when I shift to reverse no matter if im on an incline to parked flat. I have changed the transmission fluid twice and I have 60k on it so I don't think that would have anything to do with it. Also, is this something that could cause serious damage because if it isn't I don't really care about it but if it does I would like to fix it.

2011 Sonata, 42,000 miles. Every now and then the car wont start. Press the start button, everything lights up. Instead of the car then starting I hear a small clunk and then no start. I DO NOT get the "Press the Brake pedal" message. The last time this happened we tried repeatedly to start with no luck. The car then sat for a day. I tried it again with no luck. I them removed the battery clamps and cleaned the battery terminals, reinstalled, put a Start/charger on and tried it again, with the same result. I then opened the engine compartment fuse box and attempted to remove the two "start" relays. They would not come out, but I was able to jiggle them slightly. The next attempt the car started normally. Started normally again this morning.

A few weeks ago I noticed a 'clunk' noise when turning the steering wheel. It only did it the first turn on a trip. Over time it has gotten worse - the sound is the same, but it happens for several turns, maybe 10 or so, before it stops. After the car sits, turned off, for a while, the cycle starts again.
I replaced the rubber coupler on the MDPS, but my old one looked fine, and it made no change in the noise.

I don't know if this is related, but my car has not shifted as well as it did before I gave it my oil change. The car only has 3K miles, new Hyundai oil filter, and Mobil 1 Synthetic 5w-20.
It's not a major dip in performance, but enough for me to know its different. One example is when I come to a stop, the car seems to surge forward a little bit. Another is that is shifts hard from time to time when I give it gas.
Going uphill, it just doesn't have the power like it did. Also, it feels that it's not in the right gear..like 5th or 6th gear. It's hard to describe the symptoms. The weird part is that the MPG is the higher than normal.

I've had this ongoing issue where unless I first shift car from park to neutral and back again, the push button start will not work. After I do this car starts up fine every time.

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.

I've been driving my wife's sonata to work this week and notice as I start to slow down at around 20MPH the car almost surges a little bit. Maybe I am not diagnosing it correctly but it's almost like it's downshifting rough.

Today while backing into a spot at work (parked on a flat surface) my 2011 Sonata GLS automatic tranny, when I went to shift the car in reverse felt a big jerk and rather loud noise from shifting.... Haven't heard it since.... I think this happened to me once before many months ago... also on a side note why do I hear a almost a crunching noise when I am steering the car in reverse... I just had my car in for a oil change too.. I'm the only driver and owner of the car it has about 42k on the odometer.

2011 Sonata. I just started hearing, and feeling as well, a clicking noise from the shift lever while in drive. I understand this is the interlock feature, however, I do not recall feeling this before. I also thought it only activated while in park, but I could be wrong. Is this normal?
I also am noticing a loud rattling noise coming from the engine bay, behind the speedo, under certain conditions. If I use light throttle, the 1-2 shift produces a loud rattling near 1900rpm.

I have 2011 SE, it won't start at all. The car won't start all thou all electrical are working (radio, NAV, Dashboard) but when trying to press the break pedal is hard as a rock. Dashboard computer at times tells me to press the break pedal - but it wont start, it actually turns off when i press the break and hit the start button. It happen twice before was able to start it within couple minutes.

I have a 2011 Sonata with 4,000 miles. Recently, I have noticed that when coming to a stop, I hear a light thump noise in the center console area near the gear shift lever. If I put my hand on the gear shifter, I can feel it move ever so slightly at the time of the noise. The noise is very repeatable. If I take my foot off the brake and start rolling and then I reapply the brake (either softly or hard) it will make the thump noise. It is not very loud and can be drowned out with loud music, but if listening to news, it is very noticeable and annoying in city traffic, where stops are very frequent. I put the car up on ramps and looked underneath and did not see anything noticeable. It will probably require the center console between the seats to be removed.

My 2005 Impala will have from time to time a hard shift where there is a big clunk_usually 1st gear. I had it at a transmission shop last year and they could not find anything wrong. What is going on.

I have a 2005 Ford Explorer 4wd with 4.0 SOHC 6 cyl Flex Fuel. For months the vehicle has idle rough and increasingly becoming difficult to start. I decicded to replace the spark plugs and wires hoping to solve this issue! gap set to 052. When I started the vehicle it went into engine fail safe mode and wrench light came on. I then replaced the TPS on the throttle body and had no diference (I may have installed incorrectly! when I put it on the armature felt like it broke free inside the sensor). DTC codes read P0223, P2106, P2110 and with P0122 pending, P0223 pdg, P2106 pdg, & 2110 pdg.
With the old tps installed and wiring harness disconnected the truck will start in fail safe mode, but will not start at all with wire harness connected. A volt meter reads at computer end of wire plug 3.69 volts at pin one (gray/red wire +) and pin three (gray/white wire -) with key to on but not running.

So I just put in 6000k hid's in my 2011 Sonata Turbo and I want to make my DRL's brighter as well as my high-beams brighter. Is this possible? Also, I'd like to make my fog lights match my HID's, but don't know if I should put HID's in there or LED's.

I just recently bought a 95 F150 with a 351. The truck has high mileage, about 190k, and I am not sure how long the transmission has left. It rides smooth down the road, but when I put the truck into reverse it hesitates for a moment then makes a loud clunking sound(as if a door is being slammed) and then jerks into gear. The reverse works great at the moment though. Should I be worried, is there anything I can do to fix this?

Problem: The care currently has a hard start, and a fluctuating idle. I bought the car a year and a half ago it still has low miles about 94,000. The care used to start fine but had a fluctuating idle in the range of 750 to 2500 rpm. My brother who is a mechanic and doesn’t live near, do all the gaskets when he visited. Then the idle fluctuation dropped to 750 to 1000rpm, when the car rpms fluctuate there is a whirring sound I can hear from the cab, like a pump or pull system. On occasion there is a vibration as well but it is inconstant and irregular. Fuel pressure seems to fluctuate as well. If the car will not start I give it a little gas and it will run fine after a minute or two, but then the idle starts to fluctuate.
No fuse issues I can tell and relays seem to be fine.Checked for lose wiring connections found, none. I have replaced:
- Hoses and gaskets
- Starter motor
- Battery
- Fuel Pressure regulator
- Fuel Filter
- Spark plugs and wires
- TPS
- Idle Air control Valve
- Crank shaft sensor
- PCV.
Right now I’m thinking it could be the fuel pump (a nightmare to change on this car), a fuel injector failing, and the ignition switch.

I got my Sonata at 27k, its now at 76k and the cars been great although I had the following issues.
I've noticed sometimes when I startup and shift into reverse the car jerks a bit and its not a smooth transition. However other times the car is very fluid in switching gears. Should I take it in to have a look at it?
Also when I am turning onto a unleveled road (usually a higher road), I notice a creaking/knocking noise coming from the front of the car, also notice it when I reverse into a parking space sometimes.

I have a 2000 mercury cougar 2.5 liter. I bought the car without doing much research. now that i have the car did research and found out all the great problems that this car has. My transmission started to make a clunk clunk noise inside and it started to slip. At first it would go on all gears. then very rapidly started to slip in all gears. In matter of hours went from being good to being crap. i had to accelerate the car to 3000rpm or higher to make the car start moving. So i bought a transmission from a junkyard. I install it and did not work. The car did not move on any direction. I pull it out and look at it and found the small shaft that goes from the torque converter to the gear body was broken. I end up getting another transmission from the junkyard. I check it and everything looked good. I install it and got everything back together and that work on reverse but no forward. To get it on reverse I had to accelerate the car to 3000rpm. I being told that if I change the solenoid inside the transmission might fix the problem. It could be the transmission module that is burned out.
