Sonata I45 (YF - 2011+) :: Loss Of Reverse / Gear Indicator Blank
This morning, while backing out of my driveway, I lost reverse for about one second. It disengaged, just revved, then engaged on its own. I looked down and the "R" on the indicator next to the shifter was not shaded red. Put it into drive to go up the street and "D" was not shaded blue. I then looked up at the dash and the gear indicator up there was blank. Turned the car off and back on and everything has been fine since. 2011 GLS, 43000 miles.

I recently (July 2016) bought a 2012 2.0T Limited with 14K miles. Got an awesome deal on it and really love the car. About two months ago the car had a total loss of power/boost. I took it into the dealer and they performed a wastegate actuator adjustment (something I will be doing on my own now if it becomes a problem again). Now at about 21k miles I'm having a different issue. Here is what's happening:
Accelerating from a stop the car feels as if it's falling out of gear intermittently. Once it happens and I press the gas more/floor it, the car doesn't respond. If I let off the gas and then press it again, the car will then start to accelerate again. On the highway cruising at 70ish, the same thing happens and it even oscillates with constant throttle like its down/up shifting. The ESC light came after a 20 mile highway trip of this oscillation. No CEL. When I got off the freeway, the navigation screen said there may be a problem and I should press the bluelink button.
When this is happening the cruise control either doesn't work at all or the "cruise" light will come on but I can't set a speed. Tonight I noticed in the rear view mirror that the brake light stays on or even flutters after I brake which corresponds to when the cruise is or isnt working as well as when the car intermittently falls out of gear/oscillates falling out of gear with constant throttle. If I notice the brake light is on without actually braking, I can take my foot and pull the brake pedal towards me which turns off the brake light and then the car seems to work correctly as well as the cruise control. The car is driveable but definitely something is wrong.
I should mention that I checked the voltage for the wastegate actuator and it is 3.97v which I believe is within tolerance. All of these issues with no CEL.
Sonata I45 (YF - 2011+) :: Braking Noise When Coming To A Stop Near Gear Shift Lever
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.

View 1 RepliesSanta Fe (CM - 2007-12) :: 2011 - Total Loss Of Acceleration Without Warning And CEL Comes On
We have a 2011 Santa Fe we got last October. We have had four different instances where the vehicle suddenly stalled out. The first was within a few weeks of purchase and was blamed on a loose battery negative post that prevented the battery from recharging correctly. When we called the dealership service department we were told that we were not driving it long enough to recharge the battery and that the battery light would go out once it recharged. Well all the lights went out when the car died going through an intersection at night with my wife at the wheel.
The second through fourth issue is that without warning there is a total loss of acceleration then the engine light comes on. The first time this happened my wife was able to steer off the road and after a few minutes was able to restart and drive the car home. I then drove the car about a mile when it happened to me. The car was towed to the dealership where they said there was a required software update. Really?? After that it drove fine for about a month then stalled when my wife was merging onto a freeway.
The dealership checked and found three active codes: P2106 Forced Limit Power, P2110 Force Limit RPM and P0638 Throttle Actuator Control Range. They also checked TSB updates and found (12-FL-004) for ECM. They also called Tech Line and recommended change of Throttle Body Assembly. This is all under warrantly. We got the car back yesterday.
Golf IV R32 :: Hard Acceleration In 3rd Gear / Momentary Loss In Power
Having problems where sometimes the car won't go into gear, other times it's fine? The problem started after some hard acceleration in 3rd, there was what felt like a momentary loss in power. I dipped the clutch as I thought a boost pipe had popped off, all was fine (still seeing boost when revved). After this it got progressively harder to get gears, finally resulting in not being able to get into gear at all.
I found I could get it into 1st with the engine off and could go up gears normally, but couldn't change down without stopping and turning the engine off. The clutch is working fine, the biting point is normal. The problem seams to come and go randomly, it will work fine for a while and then start playing up again. When working the gearbox feels normal, there is no grinding or wining noises. I can move between gears normally and do clutch less gear changes.
There is now a vibration which can be felt at 1000rpm when stationary. It feels like it coming from the engine/gearbox and seems like something is out of balance as it shakes the whole car. The car is on 91k, supercharged running 470hp & 370lb/ft (at flywheel) and is fitted with a Spec stage 3+ clutch and solid flywheel.
Sonata I45 (YF - 2011+) :: Loud Knocking Noises And Power Loss
My car shifted wrong (i don't know how since it is automatic) and heard a loud knocking noises and lost power and then she shut down and turned off. called Hyundai assurance and they towed it to the nearest dealership since my dealership is an hour and a half away from my school. I don't know how this happened. I tried to crank it back up. heard a loud squeal maybe water pump? and she turns on but the rpms wouldn't go past 500 rpms well there she goes.
View 26 RepliesSonata I45 (YF - 2011+) :: Complete Loss Of Power Suddenly Then Reactivated On Its Own
My son is primary driver of our 2011 Limited with push-button start. He phoned me a few minutes ago to tell me he was driving--everything normal-- when there was suddenly a complete loss of power, mechanical and electrical (engine died, dash lights out, nav screen dark, etc.). There was no advance warning of any kind.
The power loss was total but brief, two or three seconds, and then reactivated on its own. My son said he pulled off the road into a parking area, stopped the engine, waited a few seconds and then restarted and is on his way home with everything working normally so far.
First issue with the Sonata--61k miles ....

Ford F-150 (2009-2014) :: 2011 - Transmission Releases And Complete Loss Of Power / Coasts To A Stop
I'm trying to fix a transmission problem with my work truck. It's a company owned, 2011 f150 super cab, 2wd, 5.0 and 6 speed auto. It currently has 225K miles. The problem is very random occurring 2-3 times per week, usually happens on start up, and goes away after a hand full of engine restarts. It has happened twice on the freeway, the transmission releases and a complete loss of power and coasts to a stop. At the same time, the speedometer goes to zero regardless of vehicle speed. Normally, when it happens, the speedometer does not read, all the mpg, miles to E, and related meters show bars "-----". The vehicle starts and takes off ok, but when it tries to shift, it just releases and the truck coasts to a stop. It will repeat this for a while.
After several restarts, the truck goes back to normal. This has happened a couple dozen times now. The wrench and check engine light came on during the very first instance, but the auto shop said there were no trouble codes stored. They kept it for a week, and said it never reoccurred. I have a lousy video that shows, when this happens, the trans starts in 2nd, jumps to 5th, then 2nd, then 5th. I am past due for a new work truck and this one is on its way out, but has to last another couple of months! This truck has otherwise been very problem free and well maintained. I'm actually thinking of trying to pick it up cheap, if the repair is not too bad.
Sonata I45 (YF - 2011+) :: Sudden Unintended Acceleration
The owner of the car claims that there was sudden unintended acceleration, and it was 09' Sonata.
Video .....
I thought this should be very concerned to us, since we all drive 11' sonata & up. I heard Hyundai installs some kinds of system to prevent this incident to all cars manufactured after May of 2012.
Sonata I45 (YF - 2011+) :: Loud Squeaking During Acceleration?
So I noticed, driving to work today, that there was this loud squeak happening while accelerating. It almost sounds like an old belt, or how old brakes sound when they are to worn. I have no idea where this sound is coming from.
The only thing is it happens ONLY when the RPM's are 2k-2.5k. And ONLY while accelerating. Other than that it doesn't make that noise.
I've tried revving to see if the noise is there. I also tried while moving, to hold the clutch and rev match to that zone and still no noise. It only happens while in gear it seems.
Sonata I45 (YF - 2011+) :: Die Intermittently On Hard Acceleration
Driving to lunch today I pulled out on the highway and accelerated hard. The Sonata didnt want to shift higher than about 4th gear (auto trans w/ the "slap stick" that comes standard. I laid off the gas and the car seemed to be running fine at that point. 1/2 mile down the road the car just died. I pulled over the car restarted fine. At this point it didnt want to shift well and died a couple times. I stopped for lunch. Afterwards I took it easy, car acted fine. Outside of work I accelerated hard again and the same thing started again.
View 10 RepliesBuick - Century :: Acceleration From A Stop Is Very Sluggish And Gear Changes Come Slowly
I am having some trouble with my 02 Buick recently. The acceleration from a stop is very sluggish and gear changes come slowly, although they still seem to shift smoothly. The first thing I did was check the fluid levels and I can find nothing wrong there. The trans fluid was last changed 3 years ago, but the level, color, and smell are all normal so surely that couldn't be the culprit ?Unfortunately, that about exhausts my diagnostic skill.

While pushing the gas pedal for acceleration from stop I feel the engine grunts more and then on its smooth. I don't have any lag in acceleration the car moves well. The car is 2008 Sonata 4 Cyl. the mileage is 137000. Is this normal for this mileage or something wrong. When I asked the service center guys, they replied they don't find any issues and everything is fine. It might be due to the mileage on the engine.

I've had my car almost two weeks, but today is the first time I've driven it with the radio off. I noticed some ticking coming from the engine during acceleration, and maybe it's my imagination, but it seemed more pronounced with the ECO mode turned on. I know these GDI engines are supposed to tick at idle, but is it normal to hear it during light acceleration too? My oil level looks fine.
View 19 RepliesSonata I45 (YF - 2011+) :: Uneven Acceleration / Idle Rough
My 2011 Sonata 2.4L GDI has already 76k miles. Spark plugs were replaced around 75K miles, Air filter was replaced. Fuel treatment was done several time since ownership, Intake CRC for GDI was used once about 2K miles ago. The car is doing good until recently. When I accelerate the car acceleration goes uneven. It is not like hesitating but you feel like the car is taking it in steps. Sometimes the first run in the morning, the car idle feels a little bit rough but that's only in the morning. It has been like that for a month now. What do you think it can be? No Check engine light, no pending codes and nothing major except that. I really suspect a bad upstream oxygen sensor (Air fuel ratio sensor). What do you think?
A look through the intake shows a very clean intake. No signs for any carbon deposit. A Hyundai dealer checked the car and told me there is nothing to worry about. Just told me to buy more Hyundai fuel treatment (AKA Chevron Techron) which was done and still I feel uneven acceleration.
