My 2015 Acura Tlx hesitates when changing gears, does not accelerate when gas pedal is pushed and the shifting out of parking position is noisy and harsh. Acura has provided a defect code for my complaints (03214) and software updates (operation number 1255A2 and 1255C9), which have been performed on my vehicle. None of these have fixed the problem. Lemon law favored in the manufacturer's side and the arbitrators say it is not a nonconformity. Honda's lawyer says that I did not take it in enough times and that hesitation for a moment is not a concern. Acura says they would not change my car because they all drive the same and that I am just not used to driving a vehicle like this one. The biggest problem with the car is that as it comes to a stop at an intersection or traffic light, it lurches forward extremely harshly as if I was hit by another vehicle in the rear. This is so bad that I have been experiencing lower back pain and have to take pain killers at times. And of course, I have to take this into account every time I have to brake, in order to avoid an accident. You must know how frustrating it is to have to worry about this each and every time I am reaching a stop sign or traffic light.. the car does it sometimes and others it doesn't, so I have to try and predict how it is driving that particular day. This takes away from me the ability to control my car in an emergency situation.also, there was one time when I needed to make a left turn and my car felt as if it were in neutral, did not accelerate and then after a moment decided to drive forward. Thankfully no car was coming, if not it would have been an accident. I have to now make sure that cars are far enough so that if it does hesitate again I won't be putting my family and I at risk. I hate having to drive my vehicle because it is unpredictable and I feel very unsafe.

Can you please investigate the 2015 Acura Tlx with the 9sp transmission? there is unintended acceleration when slowing down, unanticipated surging, and unexpected hesitation when attempting to accelerate. This is a known issue within Honda but there has been no recall or public fix from Honda. I included the purchase date of the car but the above happens at various times. acurazine.com/forums/5G-Tlx-problems-fixes-420/9at-hard-shift-1-2-2-3-A-919230

I have a 2015 Acura Tlx 4cyl. It is a very nice looking car however there is something wrong with the transmission. I have taken it into the Acura dealership and they have confirmed that there is something wrong however they are not sure what. All they tell me is that there are no codes coming up telling them what it is. They just tell me that everything is documented so if and when there is a recall I have proof that it has been ongoing. When you are stopped and then proceed to go the car will jerk and hesitate to shift to next gear. This can happen while you are driving also, if you have to brake and then start again. Its very upsetting I have owned Acura before, the Acura TL and the Acura integra, both cars had a high performance. This car not so much. When is Acura going to do something about this?? there hasn't been just one episode this is an everyday occurrence.

I own a 2015 Tlx V4 tech and there seems to be an obvious problem, which the dealerships seems to neglect, with the transmission. I've had my vehicle checked out 2 times since I first purchased it back in July of 2015, and the dealership tech. Specialists know it is there but they aren't able to resolve the problem even through a "software update". the problem is that the vehicle jerks forward, sometime when making a stop it launches forward- as if someone had rear-ended me. The secondary problem is that when I merge onto the freeway there is a major lag and the transmission fails to shift. Takes about 3 seconds to engage to full speed which in terms it's extremely hazardous because of of other vehicles that cease to slowdown and give me the right-of-way. I demand the manufacturer be aware of this issues that I contemplate on a daily basis before something tragic happens to me or my fellow Tlx drivers.

Car has 15K miles-from the time of purchase of my 2015 Tlx shawd, vehicle exhibits ( 1)rough shifting, (2) unpredictable transmission response on downshifts on highway affecting the throttle and (3) freefall feel when downshifting on downhill. Issue (1):service bulletin done to "fix" the shifting, and although better, still exhibits the rough shift. Brought the car 3 times to Acura and response is "working within spec" even when the tech noticed the hard shift and compared it to a 2016 model with no shifting issue. Now every time I know the 2-3 shift is coming, I anticipate a hard shift and have to tighten my neck muscles just in case it jerks and could cause a whiplash feel. Issue (2): When stepping on the gas pedal to make a pass on the freeway, transmission reaction time is unpredictable when at times, nothing will happen for 2 seconds, then the car will surge. This poses a safety issue due to: A. not being able to keep up with the speed of incoming traffic due to delayed reaction and, B. the sudden surge after the 2 second delayed-reaction could result in hitting the car in front. Acura released tsb 16-012 to fix this issue but does not cover earlier VIN, which include mine. Issue (3):when going downhill and car downshifts, whether manually or automatically, car surges forward giving a freefall feel before it slows down. Again tsb 16-012 was supposed to fix this but does not cover early VIN ranges. Acura continues to insist that the transmission is within spec and yet, the 2016's have a different part number for their transmission. The fact that it performs differently also proves otherwise that the early versions are faulty.

The contact owns a 2015 Acura Tlx. While stopped at an intersection, the vehicle jerked and stalled. The contact had to depress the accelerator pedal to get the vehicle to move. The vehicle was taken to the dealer where it was diagnosed, but the cause of the failure could not be determined. The manufacturer was notified of the failure. The VIN was unknown. The failure mileage was 21,000.

E-shift provides no feedback when shifting to P or D (only when shifting to R). E-shift often fails to engage. On one occasion, while reversing, I attempted to engage P, but it did not engage, and car rolled back into an object, causing damage. E-shift also requires excessively deliberate inputs, which has caused difficulty executing 3-point turns in traffic.

Transmission issue as follows: Shifts abruptly in 2 and 3rd gears. Car seems to shift up when braking then shifting down so it seems the car speeds up when it should be shifting down to slow down. When putting the car in park, the car rolls back abruptly.

- Flower Mound, TX, USA

Acura Tlx hesitates 1-2 second when turning left, right, making U turns and switching lanes on the highway. The response of the car is unpredictable and I will not let other family members drive it due to safety concerns. The shifts from second to third gear are overly harsh. I have taken the car to the dealer three times but the dealer states that the car is operating normally.

- Gaithersburg, MD, USA

Car shifts roughly when accelerating, just one of the lower gears, at around 10-15 mph. Jerks noticeably all the time, whether car is warm or cold. I did not say anything to see if it was as bad as I thought, and a frequent passenger finally noticed and asked me about it. Car does not take off quickly like I am used to. Feels very slow and heavy. Not sure if this problem will get worse with age/mileage, but I'm just hoping it won't become a safety issue.

While driving ~40 mph on an expressway the car started flashing all these warnings on the dashboard including pull over and check transmission. Looking down I saw that the car was automatically put in neutral and the gas pedal wasn't working. I maneuvered the car to the shoulder and since it wouldn't shift into park I pressed the parking brake. If the road was any more crowded we could have been killed.

When coasting at low speeds, transmission downshifts and engine revs higher and car accelerates. Must brake to avoid possible conlission

While slowly driving my 2015 Acura Tlx into my home garage and putting the car into park with the red light indicating the parking gear was engaged and letting my foot off the brake my car suddenly lurched forward about two feet before I could stop the movement resulting in damage to my drywall. The first time this happened was shortly after I purchased the brand new car and I assumed I may had not had the car properly in park and no damage occurred and it may have been caused by so called driver error. When it happened the second time 8 months later my wife and I were both in the car and observed the red parking light was on indicating the car was in park when my car suddenly lurched forward causing the damage. The Acura dealer asked to keep my car in an attempt to "replicate" the problem for about 17 days until it could be inspected by dpsm (Acura's description) and I was told no problems were detected. In researching this problem I discovered this was very similar to a prior 2015 Acura Tlx recall instituted last year by NHTSA. The Acura service department reacted as if they had never heard of that recall until I gave them a copy of the information posted on the internet. The only suggestion offered by the dealer after their inspection was to keep my foot on the brake when the car is in park until the engine is completely stopped and engage the parking brake. The mileage on my odometer was under 4,000 miles at the time of their inspection and my car is kept in a garage when I am at work and at home so environmental causes should not be a factor. I feel very fortunate that minor property damage was the only loss we encountered from this undisclosed safety defect and hope this problem can be remedied before more serious consequences occur to other Tlx drivers.

This car is a total lemon - do not purchase. I have had this car to the dealer 9 times in 12 months for non routine maintenance issues and it is getting towed there again today. Myriad of issues from lack of brakes to jerking transmission to flat out won't start. I purchased an Acura for a reliable car and that is most certainly not what I own now. I have an open case with Acura corporate but the dealer (pohanka Acura, chantilly va) will not stand behind the vehicles they sell. Buyer beware of this car!!

Leased the vehicle on 12/7/2015. After a few hours off the lot the the transmission shifted roughly from 2-3 gear. Also experienced sporadic gear shifts.

- Plantation, FL, USA

From takeoff, the gear shift from 2nd to 3rd is "hard"/firm/jerky. Almost as if there is a power hesitation then slams hard into gear. This is only gear shift position where a problem exists. Only happens from dead stop takeoff.

- Franklin, TN, USA

Hard shifts on 1st to 2nd and 2nd to 3rd causing whiplash-like reaction. Shifts occurs after what it seems to be a pause in acceleration then engine revs for 500 to 1K RPM before shifting, then the car will lunge forward. Acura has performed software updates. It reduced the hard shifts but it is still there. I have to tighten my neck and brace for a hardshift I know is coming.

Vehicle 'hesitates' or 'stumbles'. usually between 10 - 30 mph when trying to accelerate such as turning in front of oncoming traffic at a light, entering an expressway, or passing. Engine/transmission pauses 1 - 3 seconds before rpms move vehicle forward. Seems like transmission doesn't know what gear it is in or needs to fulfill the demands of the driver. I am afraid to drive not knowing when it may fail completely placing me and other motorists in harms way. Related may be the car on cruise control. Vehicle speed can vary by 10 - 15 mph. Dealership and Acura claims vehicle is performing as designed. If this is true then I have no recourse but to drive an unsafe vehicle. There are an excessive amount of similar complaints on the internet along with a class action suits. This failure was evident during test drives but I felt it was my driving technique. In all I have driven three of this exact model and they all exhibit this failure.

- Berkley, MI, USA

Hesitation when pressing on the gas pedal not safe when changing lanes on the highway and needing to gain speed quickly. Hard shift from 2nd gear to 3rd gear causes the car to jerk when driving normally on city streets. Unsuspecting passengers may experience whip-lash.

There is an issue with the Tlx AWD transmissions. Car doesn't shift properly and reports or surging or gears not engaging are being reported. acurazine.com/forums/problems-fixes-420/9at-hard-shift-1-2-2-3-A-919230/
