Elantra GD (2013+) :: Poor Shifting - Car Hesitates Then Surges Forward
Oct 23, 2015
I've been having an issue with my Elantra GT where the car appears to be shifting poorly. The issue is very intermittent and usually only occurs just after starting to drive for about 4 to 5 minutes. But it never occurs consistently during every time I start driving the car. It is an Auto transmission but it feels as if a poor downshift is being back (car hesitates, then surges forward). From my research the transmission in the GT appears to be fairly reliable.
Background
2013 Elantra GT
KMs: 98500 km (high mileage commuter to work and back)
Note: Installed K&N Typhoon around 95,000 km, issue persisted before and after.
Initially started to feel the issue around 80,000 km. At this point I took it to the dealer and had the transmission flushed. The issue went away until about the 87,000 to 90,000 km mark and then started to return. Went back to the dealer and they said they performed an updated and couldn't replicate the issue during test drives. Currently my car is at 98,500 and this morning when driving to work the issue was particularly severe and the check engine light came on.

We are traveling and the 05 gx isn't doing so well. It has a bad hesitation and speed and getting really bad mpg. Like 14 mpg on highway. Cel is on but the only code is o2 sensor. Bank 2 sensor 1. Would that really cause this big of an issue?

2006 Chevy Express 3500 ... Vehicle surges, hesitates, stalls, backfires, and is hard to start after stalling.No codes are thrown, and have had the fuel system checked out without results. 159.000 miles. last mechanic said it was not a spark plug issue. Been an ongoing problem for several months and getting worse all the time.

03 supercrew 5.4. I've been having problems climbing hills. I'm on a trip and the truck surged fron do then to drive and stopped. Let it sit for 30 mins or so and it was good. Drove another 500 miles ans started again going up some hills. The first time it was 110 out and the 2nd it was 90. I'm pretty sure it's a cop but of course no cel. It does not seem to of over heated either. Can the cops overheat? Do you recommend a diagnostic, will this show up if no cel has show?

I owned a 09 Prius for 8 weeks, and after a total loss accident, we replaced it with a 08 Touring model. I have never experienced anything like this with the 09, but have multiple times on the 08 (though no real rhyme or reason as to when/why)
The originally happened the night we picked up the 08. I stopped at target to pick up some milk while the wife sat in the car. the car was left in ready mode. when the ICE engaged the car "surged" forward and was enough to startle my wife (who was the usual driver of the 08) enough for her to think the car was not in park (which it was)
We tried to recreate it after i was finished at the store, and while the car did rock forward, it was not as pronounced as the first time (though much more then We feel the car should move upon the ICE starting.)
Took the car back to toyota, and they preformed a full inspection and stated that everything was within toyota's spec, and to keep an eye on it if it were to happen again.
Well it has done this about 5 times in the last few days. The Dealer is looking in to it.

I am having issues with my 2002 chevy cavalier.
The car occasionally surges forward while idle and revs up to 1500 rpm approximately occasionally when the air conditioner is on... if the brake is not applied I move forward.. the lurches are continuous every 3 seconds or so.
I am getting a code for an evap leak.. I have replaced the purge solenoid valve, gas cap, and checked all connections with no luck... slightly decreased gas mileage has occurred.
A little bit of a slick substance has been leaking from the car.. it has the consistency of water, but leaves a slight brown tinge on concrete.

My 2013 Elantra won't shift out of park. I know that I should check fuses, but what fuses might be associated with this. (The brake lights are not affected).

I have a 1999 toyota tacoma 70,000/mi. While idling, at random intervals, truck surges forward. Have to stay on the brake. Cannot drive in winter. Took to Toyota dealer and other mechanics... described problem and that A/C seems to be on all the time. No one has been able to fix. My brother disconnected the A/C and surging has stopped, but I need a better fix that will allow my using AC.

So this doesn't begin until I put it into a forward gear, but after about 30 sec of smooth running, I will get a sudden momentary loss of power, then a surge, which repeats and intensifies as the van lurches forward until the engine finally stalls. Throwing it into N in the middle doesn't work. Babying the gas had no effect. It happened both at higher(2.5-3K) revs and at lower (.8-1.5k).
After killing the battery starting and restarting it just to keep it moving, I had it jumped, at which point I sat with it in P for 20 min to charge the battery and in all that time, it ran fine. I'd love to hear some possible diagnoses. Don't know if I should have it towed from where it's sitting, or try to drive it to the shop, or if it's something I can repair myself (think 1-star difficulty).

2010 F150 for the past 15,000 miles I have been experiencing a nasty repetitive surge when moving slowly forward with the brakes on, as you would do going through a drive through. The truck shakes when this happens and is very noticeable. Ford reprogrammed the transmission module, and now the surge happens twice as fast. What was the remedy? This is my first Ford after only GM products for the past 30 years.......and I hope they can find a resolution soon.

Here is a video I made of the "Blow off" noise I hear when accelerating/shifting (more than 50% throttle). Sounds kinda cool IMO

I recently bought my GL less than a week ago with under 10km on it. Its been great so far but I noticed a weird movement when shifting into 3rd gear (both up and downshifting). It started happening about 2 days into driving the car.
As I shift into third gear I feel a little kickback against the forward motion. It doesn't happen all the time and it doesn't seem to be dependent on the car speed or the speed of my actual shifting. Although it happens a lot more when I shift quickly into third.
I've been told that 3rd and 5th gears are the longest and I might just need to get something adjusted at the dealership.
This kickback doesn't happen on any other gear except third (MAYBE I felt it a little on 5th but I may have been searching for it after being told about 3rd and 5th gear being long).

Overall, my wife and I like the car. It feels solid, and so far we have about 950 miles on it. Today though, something weird happened.
I was driving, and we were getting on the freeway after crossing an overpass, so it the on-ramp was one of those sweeping, downhill, 270 degree curves to the right. Nothing out of the ordinary.
So I let off the gas, and I'm taking the turn, and there was this "thump!" noise - almost as though the transmission was shifting. The car shuddered. Then it did it again.
It was disconcerting, almost reminiscent of our wacky dual-clutch transmission issues we had with our 2011 Ford Fiesta. Now granted, its a bit of conjecture since I don't know what could have caused it. I wasn't going quickly enough where any stability control mechanism (ESC) should have kicked in... so I'm not sure what else could have caused it. Undoubtedly I'll be testing it again to see if I can reproduce it, but its got me concerned.

Well something I never thought would happen with only 14,313 babied miles on my 2013 silver Elantra. I was driving home from my mothers house and I thought I hit a pothole, next I stopped at a stop sign took off and it started shifting very rough through most of the gears. I drove it around for 30 minutes and it was pretty bad. I decided to get it towed, I don't feel like breaking down in it.

I have a 1986 Volvo 240. It has a button to push on the stick shift to put it in 5th gear. It drives and works fine except when I downshift from 5th gear. ..then it seems confused and has a hard time getting back into gear, it kind of hesitates and lurches forward. It will not go into reverse after it has been in 5th gear until I turn off the ignition, and start it again.

When cold starting the transmission shifts into reverse perfectly, then after backing up the car and shifting into drive it hesitates for 4 or 5 seconds before it engages the forward gear.

2002 Santa fe 2.7l v6 trouble code p1529 p0121 p0129 p0740...
I'm having erratic shifting problems and poor gas millage. The issue began approx 2 weeks ago and is always present. The issue is hard shifting between all the gears, jerking, high tac revving , difficulty shifting from 3rd to 4th gear and throttle at times unresponsive, and like i stated earlier poor gas mileage.
This past weekend I replaced the TPS, but the TPS codes are still present. One concern I have with the replacement is that I din't detach the negative cable, which I've recently learned should be done. So I'm not sure if by neglecting to remove the battery cable I may have damaged the new TPS.
Is it true that the negative battery cable should be removed with TPS replacement?
I've also read that a faulty TCM can cause these types of symptoms as well and one resolution may be to reset the TCM by removing both battery cables.
Any information on resetting the TCM? Also, in case I decide to replace the TCM, where the module is located ?

My 2016 Forrester hovers or rolls back for at least 2 seconds after shifting into Drive after Reversing, even though the gear feels fully engaged in Drive and I am stepping on the gas. Consequently I was almost hit by a truck when reversing out of my driveway. I was stuck hovering for 2 seconds before I could drive forward. I brought it back to dealer who said it is "normal" with all makes of new cars. I have not experienced this, nor have my friends.

I have a 2007 Chevy Equinox with 104,500 mi. For the past 20,000 miles (2-1/2 yrs.) or so the transmission hesitates when shifting from 2nd to 3rd gear. When this happens, the engine revs and the wheels lose power for a second or two, and then the shift completes.It happens anywhere from once or twice a week, to once a month.It never produces a "Check Engine Light" nor a "Code" when scoped the same day.It is more of a nuisance, although doing it while pulling into traffic could cause a nasty safety issue.I have had it checked by independent mechanics and a local Chevy Dealership and nobody has an answer.

Our 2004 LeSabre has the following symptoms - there's a clicking that occurs whenever the car is in motion, the car occasionally hesitates/bucks when shifting between gears (but not always), the radio sometimes does not go off when the keys are taken out of the ignition, we're losing about a quart of oil about every 2500 miles but there is no sign of a leak on the ground, we also seem to have reduced mileage (using more gas).
In this corner, Mechanic 1 (high price) - replace front lower control arms, sway bar, and bushing, front end alignment, throttle body gasket and EGR tube, oil pan gasket replacement, ignition switch replacement, brake fluid and coolant flush. $1900
In the other corner, Mechanic 2 (low price) thinks it's just the spark plugs and wires that need to be replaced, the wires, replace air and fuel filter, and PCV valve - $450
We had the oil changed about 2500 miles ago, replaced the air filter then. The oil change place suggested a coolant and brake fluid flush. I've used mechanic 1 in the past and they have replaced my head gaskets a couple of times and I suspect they are ripping me off.
