Sonata I45 (LF 2015+) :: Slight Stutter At Highway Speed When Going Uphill
I just picked up a Sport. I've noticed 1,2 quick stutter type thing happening intermittently at highway speed going up a hill. Dealer service probably won't be able to have it happen as it only has happened 3 times in my 400 miles.

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.

My new LS460 AWD 2008 is jerking on 60-80KPH(37-50)MPH, when you driving without any acceleration.
I have only 900km on odometer. And it's started jerking from 0. I gave my to Lexus for a test. They tested it over 7 days, and now they are saying nothing is wrong with it. And it's normal for AWD version.( WHAT???? )
They have one more new AWD 2008 and it has the same jerking issue.
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Occasional Miss At Highway Speeds / Bucking And Jerking During Even Gentle Acceleration
165k miles 4x4 6 speed, bone stock unmolested
Slowly progressing problem over 6 months. Occasional miss at highway speeds uphill has progressed to bucking and jerking during even gentle acceleration attempts.
I hadn't got my cam sensor recall done but no change after that procedure completed yesterday. Oil recently changed as well.
I have a torque pro but it never finds any fault codes even though 'service engine' light comes on sporadically. I'm not sure I'm operating it properly but it at least reads rpm when its running.
I'm contemplating the hutch mod but I'd like to have an official diagnosis beforehand if its possible in my case.

View 21 RepliesSonata I45 (LF 2015+) :: Cabin Vibration At Highway Speeds
So about 5 months ago I started feeling vibrations in my seat and steering wheel. I got my tires road force balanced and it solved the issue. I just got back from a weeks long vacation in Maine. Before I left I had the tires road force balanced again to ensure a smooth ride up. I left some shaking in my seat so I wanted to get it ironed out.
While driving up my seat and the entire cabin shook when I exceeded 70 MPH, it got worse and worse the faster I went. The steering wheel didn't shake at all. I figured the tech balancing the tires did a bad job so I visited the BJ's in Portland. They re-balanced all my tires, I was present when the job was being done and noticed they were all out of balance.
The BJ's tech said it look like the shop that did the balancing over balanced each wheel (too much weight on each wheel). As soon as I hit the highway the same thing happened, shaking above 70MPH. At this point I determined it was probably a bent wheel. I visited a local wheel repair shop, they checked out both my rear wheels, since the steering wheel wasn't shaking I didn't bother checking the front ones.
It turns out both rear wheels are ever so slightly bent, they attempted the straighten out the more bent one. They tech repairing the wheel said he was surprised I even felt anything at all. So I had my hopes up that the problem would be fixed but as soon as I hit the road the same shaking returned. At this point, what's wrong with my car. I'm thinking of buying 4 new wheels, the car came from the factory with low profile 18 inch wheels which have been a curse.
A few more details about my car:
Toyo Proxes 4 Plus - Ultra high performance tires (Maybe contribute to harsh ride?) 20K miles on them
Installed thicker 20mm rear sway bar 6 months ago (But I never had shaking until now)
Installed front tower strut bar 6 months ago.
Total mileage 32K
I have hit lots of pot holes the past 2 winters lost 2 OEM tires and bent 1 wheel last year which was repaired.
Also I can't drive through it, the shaking doesn't stop with more speed it only gets worse. And the back end has started to feel squirrely over bumps.
Tiguan :: Misfire Occurs At Highway Speed Under Acceleration
Misfire occurs at highway speed under acceleration, the service writer stated "we have to do a coil swap" meaning they just swap them from around, and this is the SECOND time they have done this, according to them this is how VW wants them to address this, now I understand factory procedures cuz I work for a Porsche dealer, but wouldn't you think second time around you would replace those things.

During very smooth acceleration at any speed, steering vibration is felt which seems to come from bad engine support absorbers. Dealer said this is normal due to powerful V6 engine. Also hear disturbing exhaust sound when accelerating. Wonder if these conditions are related to steering vibration?

I have been having a grinding/metallic sound when going up hills in 4th/5th gear. It sounds like if you threw metal into moving parts. I believe it's coming from my engine or transmission. When i was at the dealer last month for a campaign and ecm upgrade i mentioned this problem and they replaced the vcm motor assy, however the problem still exists. What could be causing this problem?

New Sonata owner. Got myself a 2015 Ultimate. Is there much difference in acceleration between "Sports Mode", and just running the car in manual mode (shiftronic)?
I know my Elantra used to have a huge acceleration bonus if I ran it in manual mode. Not sure if that caries true here.
Sonata I45 (LF 2015+) :: Hesitation Upon Acceleration And Check Engine Light Came On
I bought a pre-owned 2015 Sonata Limited in November. I only had less than two weeks before the car hesitated upon acceleration and the check engine light came on. At the time, I thought it was a loose gas cap as I'd just gassed up. I took it to the dealership, they pulled the code and it said to replace the accelerator pedal. That required a second trip to the dealership 2 weeks later when they completed the work. Two weeks later and the light came back on. I took it back and asked them to keep it until they found and fixed the root cause while I took a loaner. They kept the car about 2 weeks and when I picked it up, I found that no work had been completed. Two days (!!) later the light came back on.
View 11 RepliesSonata I45 (LF 2015+) :: Engine Starts Hesitating Around 5k RPM Under Hard Acceleration
I'm on my second '15 Limited Turbo. Only have 2k miles, but I've noticed an issue with acceleration. When under hard acceleration, especially in 3rd or 4th gear, around 5k RPM the engine starts hesitating. It feels like it runs out of steam. This feeling lasts through beginning of next gear, then the car picks up again. It is actually faster when applying less throttle.
What it could be? It did it since new, I took it to the dealer once, but got some stupid response that it was just rev limiter kicking in (at 5k, right), unfortunately had no time to leave it with them again/show it to them. I also thought it might just go away on it's own, plus I don't usually drive it that hard anyway...
Sonata I45 (LF 2015+) :: 2016, Low Speed Solenoid Noise
2016 LTD 7200 miles. Been to the dealer twice for routine service (oil change both times, tire rotation and air filter change as well second time. First and last time they are changing air filters; what a freakin rip off)
So this noise occurs at very low speed (1st or second gear) and very consistently occurs when lightly pressing the throttle and usually occurs when releasing as well. It sounds like a clock tick and in fact sounds very similar to the shift interlock solenoid sound you get when tapping the brake while in park.
Furthermore it doesn't happen from a cold start. Car has to be driven a bit and brought up to normal operating temperature; for example I can't reproduce the noise at all first thing in the morning before heading to work, but can with no problem once I'm at work creeping though the parking garage. So I think this rules out any gear slack or other such mechanical slop that could make noise when load is first applied and then again when released. Also it's not audible with the windows down. Cabin has to be very quiet to notice (again, like that shift interlock solenoid tick).

My 2009 sonata started having issues with slight up and down accelerations while cruising and the check engine light would come on Then during start up the engine would accelerate up and down about 1500 rpms. I have taken it to two dealers neither could find anything wrong and said their was no record of an event on the computer. Now the car is stalling while driving, once at highway speed. It has happened three time this week. After coming to a stop, I wait a few minutes and the car starts up like their is nothing wrong. The engine light comes on for a while.
View 9 RepliesSonata I45 (LF 2015+) :: Cruise Control - Transmission Will Downshift To 4th Speed Whenever Go Downhill
The cruise control on my 2013 works as I expected.
However the cruise control on my 2016 Sonata does not.
When driving at highway speeds (65 to 70 mph) in cruise control and the shifter set on "D" (drive) the transmission will down shift to 4th speed whenever I go down hill.
This might be intentional as a way to keep the car from exceeding the set speed, but I have never heard of this and it would seem to place more wear an tear on the transmissions.
Do the down shifting is engineered in or if it is a service problem that I need to have addressed...
