While the vehicle was unattended (no driver present) and transmission was engaged in park; I was present when using the remote started. Upon starting (vehicle was started), it rolled up a slight inclined driveway roughly 3-6 inches, under power; then rolled back she same distance. Then a distinct click was heard. The car continued running in idle as normal with the remote start. Acura has reported transmission issues with the potential for the car to disengage from park (model sh-AWD) and roll away. This car was recalled for "roll" while parked and not running, , but passed and inspection by the dealer. Unlike the previous recall this issue entailed a "shift into forward", from park, under power while unattended. I notified Acura customer service to report it, was told to bring it in, but if the issue cannot be recreated then it cannot be repaired. This event coupled with the previous recall, has me concerned that Acura is not addressing serious safety concerns of its consumers.

Vehicle has inconsistent shifts in lower gears. Also, shifting is inconsistent when pushing down on the accelerator.

I noticed the first time I accelerated quickly to merge onto the interstate that the engine hesitated at least a second to second and half before accelerating. After that, I started noticing the same hesitation whenever I punched the gas pedal to either merge into traffic or pass someone. I have read on the internet where other owners of this vehicle have the same problem. I just took the car in for it's first oil change and I complained about this issue. The dealer ran several computer software updates on my car and said that it was up to date and that basically that is the way the car is. I feel this is a big safety issue. I have adapted to driving the car with this hesitation, but I'm not happy with it. I think Acura needs to address this problem before someone gets hurt.

1. step on accelerator and the car jolts forward like it is in the wrong gear or you slam the accelerator, or the clutch is released rapidly. Jerks ones head back. 2.come to a stop, transmission downshifts hard causing the car to lunge forward overpowering the brake. (engine at idle). Most of the time it feels like someone has tapped you from behind.. when it occurs it is usually the first 2-3 times I come to a stop in a trip. 3.driving on level or slight decline, let off accelerator and slow to make a turn to go up a hill, step on accelerator as you transition uphill transmission slips out of gear (as if you are holding the clutch in and releasing it too slowly) then searches for the correct gear required to go up the hill and accelerate. (engine near idle) 4.most of my driving is in the city.. stop and go.. slow and go...

- Kansas City, MO, USA

Attempted to merge into an appropriate gap in traffic that was going approx. 45mph. Car hesitated for roughly 2 seconds before downshifting into a lower gear in order to pick up speed, this caused other drivers to react to my much slower car not picking up speed as it should have. Acura has been contacted many times and has failed to fix this problem, inherit in these cars from reading complaints online about this car.

- Sugar Land, TX, USA

The contact owns a 2015 Acura Tlx. The contact stated that the vehicle experienced abnormal jerking between gears, abnormal acceleration when starting, and abnormal shifting while driving 45 mph. The vehicle was taken to a dealer where it was diagnosed that the transmission fluid needed to be replaced and the shift point software needed to be updated. The vehicle was repaired but after 500 miles, the failure recurred. The manufacturer was not made aware of the failure. The approximate failure mileage was 1,500.

- Puyallup, WA, USA

This car continues to jerk back and forth, fail to find the right gear, and downshift suddenly regardless of what driving mode you're in. There have been times when pressure is applied to the pedal and nothing happens creating dangerous road situations. The transmission is a complete failure and I've been told that there is nothing the dealer can do about it.

- Fresh Meadows, NY, USA

When driving at approximately 40 mph the car suddenly accelerates. I first noticed problem when coasting downhill, but now occurs on level highway also. Also there are periods when one tries to accelerate from a stop or from reverse to drive that the transmission hesitates before shifting into gear. At that point the engine has revved up causing the car to lurch forward when the gear does engage. Additionally even after a recall, the parking gear slips allowing the car to roll down hill. These problems have resulted in near accidents. Updated 11/18/15

Transmission is very jerky at low speeds when cold and hits a hard shift between 2nd to 3rd gear. All other gear changes are unnoticeable however 2nd going to 3rd always shifts hard. Read online and other owners are having the same issue. Despite the fact that certain cars are being recalled for transmission issues, all Tlxs should be checked

It seems like my brand new Acura Tlx is having issues with its zf 9-speed transmission. It hesitates and shifts hard going from 2nd to 3rd gear. A lot of Tlx owners having this issue and there is currently a 9-page thread on acurazine about this issue. You can read more about this issue from this thread: acurazine.com/forums/problems-fixes-420/9at-hard-shift-1-2-2-3-A-919230/ I took the Tlx to the dealer and they have done a tcm reset and idle relearn. It seems that for a couple of days, the shifting was smoother after the reset. Unfortunately, the issue then recurred. My Tlx still shifts hard between 2nd and 3rd gear. I'm a little bit concerned about safety. Sometimes, this hard shift or hesitation happens as I am turning left from a stopped position. I am concerned that I wouldn't be able to turn as quickly as I need to be. In fact, this exact thing happened this morning. I am thankful that the car that was going straight saw me and slowed down.

9 speed zf transmission shifts roughly from 1-2 and 2-3 with 2-3 being the worse. Dealer service states this is normal for the transmission do to torque matching or something like that. I find that hard to believe based on all the other issues this transmission is having in other manufactures vehicles.

- Livermore, CA, USA

The contact owns a 2015 Acura Tlx. While driving at 60 mph, the vehicle shook violently. The failure also occurred when shifting from first to second gear. The failure recurred numerous times. The vehicle was taken to a dealer, but was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 550.

Trans shifts are very jerky up or down. Sometimes does not downshift when braking. Scares you when you have to slam on the brakes to slow down or throw car into "N". pulling out into traffic can be scary as there is often a delay between acceleration and the engagement of the tranny. Then the jerky shifting occurs. I am not always sure if my car will pull out into traffic quickly and safely without me being rear ended. I will not let my wife drive the car. I will be going to the dealer this week for service. I have waited this long because the sales person told me the car needs 5,000 miles to "break in" the tranny. I have noticed reading on the web that this seems to be a common problem with the new model (8 speed double clutch auto with 4cyl. Engine.) it seems that american Honda has issued a tsb #15-021 (dated April 23, 2015. That addresses the problem, but I keep reading that this fix is not working and that many dealers are telling the customer "it's the way you drive it. We are not getting any bad computer codes". american Honda in concert with their dealership network are covering up a defect that is very dangerous safety problem. This is growing into a major problem...I will begin to document all future dealership paperwork in anticipation of filing a claim under my states lemon law. I will never buy another Acura again. My first was an Acura tsx and it was an excellent car. I am very surprised that Honda has done down the tubes. By the way, this is the first Acura model built in the usa versus Japan. Had I known that, I nwver would have purchased this car.

Car jerks noticeably when shifting from transmissions gears 1 to 2 and then from gears 2 to 3.

- Lewisville, TX, USA

The car has times where it stalls or hesitates significantly - this occurs worst in shifting from reverse to drive (there is a several second delay and then a surge forward), and there are hard shifts between 1-2 and 2-3 gears. There are also times where when coasting and you apply throttle, it is unresponsive. There have also been situations where the car downshifts very hard and lurches forward almost uncontrollably (this has only occurred in sport+ mode).

- Flower Mound, TX, USA

I leased an Acura Tlx (4-cylinder) in October 2014. Almost since the beginning, the transmission of the car has been very jerky and stiff, especially when cold. There are times when pressing the gas pedal produces no effect, and there have been times when I have pulled out into an intersection and the transmission seemed to shift into neutral, leaving the car motionless for seconds. The hard shifting occurs primarily when the car is cold, and in the lower gears. The feeling of shifting into neutral occurs randomly with no obvious contributing factors. I returned the car to the dealer when the car had about 200 miles on it, and they claimed to find no problems. I have not returned to the dealership since (the car has about 5300 miles on it now), but I will be returning in the near future.

To whom it may concern, I own a 2015 Acura Tlx (4 cylinder model with 8 speed automatic transmission) which I purchased a few months ago and would like to file the following complaint: 1.on stop and go traffic the transmission is jerky (almost every time). This means that when the transmission shifts, it creates a shutter that reverberates throughout the car. 2. after driving 1 mile or so and coming to a complete stop, especially during cold start, the transmission lurches forward very hard ( like someone rear ended) doesn't happen all the time but happens often to dislike (four times total). Very scary when you feel like you may rear end someone. 3. when slowing down, say coming to a traffic light and not coming to complete stop and making right or left turn at say about 10mph speed or so, and hit on the gas pedal to speed up, the transmission hesitates and doesn't know which gear to engage thus making very jerky feel. 4. every time cold start, transmission shifts in 1st and 2nd gear are very hard. Dealership claimed to test drive the vehicle and then proceeded to tell me that this was "normal" for the transmission to do that. I find this very unacceptable! this car needs to be recalled and they need to find a resolution because this is a severe safety issue and a threat to my own personal safety. Acura, take some responsibility and fix this issue, I'm not the only one experiencing these problems.

I leased this vehicle in September of 2014 and immediately had concerns with the transmission. The shifts between gears were extremely rough and choppy. When the vehicle was at a stop, I would press on the gas to move into traffic, but the vehicle would not respond; instead, the rpms would rev all the way up to 4-5 and after a couple seconds, I would be lurched into oncoming traffic. I have almost gotten into two significant accidents due to this issue. I have now had to change my driving completely to allow for more time in an intersection to avoid being seriously hurt or killed. The dealership and Honda motor vehicles both refuse to be responsible for this issue and despite my vehicle being in for repairs four times now, claim they are "unable to duplicate the issue." Rather than taking responsibility for this issue, they accuse me of driving "aggressively." Please do not buy or lease this vehicle. It is a major safety issue that the company will not/has not resolved.

- Elk Grove Village, IL, USA

It is shifting hard when it downshifts, it is slamming into gear when downshifting. When starting from a dead stop it sometimes will just rev up and not move, you have to let off accelerator then push again to get it to move. When cold the transmission jerks during normal shifting. This does not happen all the time, is only does it occasionally, it is at dealership right now and they say nothing is wrong.

- Panama City Beach, FL, USA

I least a 2015 V6 Tlx in 10/16/2014. Few days later I started felling the transmission shifting roughly and jerky from 2nd to 3rd gear causing the car to jump forward. This happens almost every time especially in stop and go traffic.another issue am having with this brand new car is the unresponsiveness in acceleration and the delay while trying to merge on the freeway or trying to change lanes passing another vehicle. By the time it accelerates, am either close to the vehicle in front of me or the approaching vehicle is close to rear ends me. Also while accelerating through an intersection, this car fells like there is now power or the gear in neutral mode. These are very dangerous issues am facing with my daily driver. I don't fell the safety in this car for me or my family, especially we are expecting a baby in couple of weeks. Acura dealer keep on saying this is the way the car is and they have no solution.
