Transmission rough abnormal shifts at RPM 1000, stop and go driving.

- Mechanicsville, MD, USA

Did my latest software update that came out on 02/09/15. Unfortunately it did not fix the problem. I am big Honda/Acura fan but the new Tlx 8 speed dual clutch transmission is a big letdown. This is my first Honda product that I am tired of and want to be replaced. Here are some of the scenarios that the transmission does not act normal and could be dangerous long lag and heavy clunk shifting from "R" to "D"; delay during acceleration after momentarily letting off gas - engine revs up and then the car slams into the gear that it finally selects - especially dangerous when coming out of a corner or attempting to accelerate after yielding in an intersection; occasional hard jerk when stopping (like the car has been rear-ended); random rough shifting at slow speeds, etc. These problems are not just uncomfortable, they're extremely dangerous! 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. 4. 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.

Long lag and heavy clunk shifting from "R" to "D"; delay during acceleration after momentarily letting off gas - engine revs up and then the car slams into gear; occasional hard jerk after stopping (like the car has been rear-ended); random rough up and down shifting at slow speeds (under 40mph) car was purchased new and has had these issues since purchase.

I leased my Acura Tlx V6 advanced 2 wheel drive starting in September 2014. Right away, within the first week I started noticing performance issues. This vehicle has an extremely hard shift between 2nd and 3rd gear, causing the car to lurch forward unexpectedly. It is particularly noticeable in "sport" mode. It happens more consistently in stop and go traffic, which coincides with a situation that allows for less reaction time. It also has serious acceleration hesitation throughout all speeds. There have been multiple situations where while merging in traffic or accelerating onto a major highway I have almost been hit because my vehicle was unresponsive. My car has been into Acura twice so far for this issue. The first time I was told it was a "known" issue but there was no fix. The second time I took my car in for the safety recall Acura "changed out the transmission fluid" which was supposed to help - and it didn't. I have another appointment next week for the same issues. Acura client care acknowledged that this is a known problem but that Acura corporate does not have any solutions and it must be taken up with the dealership. The dealership just acknowledges the problem and says to take it up with Acura corporate. This is a dangerous driving situation and I do not feel safe in this vehicle. Acura obviously rolled this car out of the factory knowing they had issues (hence their launch delay in the first place) but were willing to take advantage of the consumer and had no concern for their customers' safety. Buyer beware - do not purchase a Tlx.

The vehicle has a bad hesitation which makes maneuvering in and out of traffic dangerous. Several times while trying to accelerate and pass another vehicle I was almost rear-ended because of this hesitation. After several seconds of hesitating the vehicle lunges forward the RPM indicator shows a drastic increase and the engine fails to down shift properly. I have also noticed after I park my car and get out I notice a burning smell resonating from underneath the vehicle. I have brought my vehicle is for service the dealership has told me there are flaws in the Tlx model and there is nothing they can do. I have also contacted Acura corporate and they have been unresponsive. My feeling is the issues plaguing this car could pose a danger to the driver and other vehicles.

The contact owns a 2015 Acura Tlx. The contact stated that while driving at various speeds, the vehicle jerked and changed gear aggressively. The vehicle was taken to the dealer several times for the failure. The dealer downloaded the computer software but the failure persisted. The manufacturer was not made aware of the failure. The approximate failure mileage was 5,000.

- Jackson Redmond , WA, USA

The car lunges forward when I take my foot off the gas and have very little time to apply the brake. As a result, the car seems to pull forward and require additional braking to stop. Very rough shift between second and third gear. There is also a delay or hesitation with acceleration. The dealer told me they could not pull any diagnostic error codes, all the other cars on the lot they tested have the same problem and they received numerous complaints. The dealer is waiting on Acura to come up with a solution.

Car jumps when shifting between 1st and 2nd and 2nd and 3rd. If I take my foot off of the accelerator right before it shifts, it shifts and jumps forward. I own the V6 advanced 2 wheel drive model.

- Boca Raton, FL, USA

The safety incident(s) to be reported: 1) vehicle seemed to jump into neutral' when decelerating almost to a stop (e.g. to make a turn) resulting in the engine revving and no power when the accelerator is pressed. Tach did not move and the transmission display still reads D. this left me in the middle of an intersection with no power being delivered to the wheels. There was no oncoming traffic. Unfortunately this has happened repeatedly when the engine is cold. So far there have been no accidents. Each of the following safety problems are also ongoing: 2) intermittent and variable duration hesitation from a stopped position (or slowed down to around 10mph or less and then accelerating) makes it dangerous to turn swiftly across oncoming traffic. 3) intermittent and variable duration slipping when trying to accelerate from a slow (10mph or less) coast makes it dangerous to perform any maneuver that requires a swift and reliable response from the transmission. 4) intermittent and variable duration revving between gears when kicking down to try to pass another vehicle makes such maneuvers risky.

I own a 2015 Acura Tlx 2.4L 4 cylinder: 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. 4. 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. 5. every time cold start, transmission shifts in 1st and 2nd gear are very hard.

I returned the car the day after purchase because it was lurching forward upon shifting gears, the shift was very jerky. The dealer did not diagnose a problem. I tested the car in all 4 drive modes and there did not seem to be a difference in the jerking forward. The jerking problem continued and I again took it to another dealer in fl. This dealer also stated no problem. I called the dealer that I purchased the car from, Chevy chase Acura, and the sales person suggested I return the car to their dealership when I return to md. I emailed the service manager but have not had a response. The jerking forward issue remains a problem.

I was accelerating from 40 mph to 50 mph when the car suddenly stopped accelerating, beeped, and started flashing all system errors in orange on the dash display. The car would not go above 50 mph, as if the gas was being choked off at that point. Car was towed to dealer. They had the car for a week before it was "fixed". the exact same error just occurred for a second time while I was accelerating and merging into a busy highway lane. Car is again at the dealer for almost a week and counting. While it hasn't caused an accident yet, this is extremely dangerous. I was nearly rear-ended when my car stopped accelerating and started decelerating on a busy highway. In between these occurrences, I have had other random errors, such as the lane departure warning system activating while driving straight down the center of a lane. When this occurs, the steering wheel is "tugged" towards the direction it thinks it needs you to go. Very dangerous when the car is trying to tug you out of your lane into another. The random errors that occur are all with the same systems that flash error warnings all over the dash on the two occasions that the car has stopped functioning properly. Ldw, acc, braking system, vsc...all important safety systems!

The car has a had a hard or delayed shift from reverse to drive when cold from the time I bought the car, but last week the car slipped/shifted out of gear like it was in neutral when I accelerated from a stop to go through an intersection. The car was in economy mode at the time. Acura did an update on the transmission for hesitating and lurching around January 15, 2015. The car is at the dealership now.

- Bedford, TX, USA

When accelerating from a stop when the transmission is cold, there is a lag time from the time the accelerator is pressed to the time the car moves, and when the car moves, it lurches through the first few gears. Can be dangerous if not totally paying attention. Also, when approaching a stop, as the electronic transmission downshifts to the lower gears, the car also can lurch when getting to the first gear. When backing up and going from R to D, there is a 2 to 3 second lag until the car goes into D mode. When backing out of driveways, give yourself plenty of time! I have had the car in 4 times for "software updates", but it does not address any of these issues.

Issue 1 - basically, when the car is cold (as in hasn't been driven for about 3 hours or more) it shifts pretty hard 1-2, 2-3, etc. Regardless of the ids mode. However, it seems that it is less pronounced in "econ" mode, probably because it softens the shifts a bit. Sometimes it is more noticeable than other times. It also seems that it is even slipping a bit when accelerating from a stop, kind of like in a manual transmission when you let the clutch slip too much. When the car warms up to operating temp, I really don't notice it shifting hard at all, and in fact the shifts are almost imperceptible 90-95% of the time. Issue 2 - 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 a very jerky feel. Issue 3 - I have noticed is that when coming to a stop, sometimes it really slams into first gear, and I mean hard enough to shake the car. This happens rarely, but when it does its very disconcerting. Issue 4 ? there is the 3-4 second delay when I engage the car into the (D) drive position either from (P) park or reverse.

There was no accident. This car is the 4 cylinder, tech model. The transmission hesitates shifting from reverse to drive. It also will hesitate when turning a corner sometimes. The other problem with this car is the climate control system (listed as electrical above). It simply doesn't work correctly. The driver side tested 8 degrees different than the passenger side. So if I have the drive side set at 75 degrees for heat it feels like 68 degrees. When on the heat setting, the fan appears to disperse more out of the defroster than it does below the dash. I have to turn the car climate control setting on the driver side to 80+ degrees and use the ac dash vents to keep my upper body and hands warm. There are many complaints on the Acura Tlx forum about the climate control issue. I have made attempts to get Acura to address the heater climate control issue.

There is a very rough upshift from second to third, on a long right hand turn when transmission is cold, in the middle of the turn, power to wheels disappears and reappears when road straitens, transmission/car surges forward on down shift 3 to 2 (sometimes).

- Acworth, AL, USA

Issues with transmission shifting. 1. delay of acceleration at low speed such as at an intersection (4 occurrences) where making a turn car does not readily accelerate due to being in too high of a gear while in automatic mode. After about 2 seconds, car downshifts and resumes normal acceleration. Has not recurred in at least a month. 2. rough shift (lag) when car upshifts from 2nd to 3rd. This has been present since purchase and occurs regardless of what mode (auto/manual) is selected. Has not improved. 3.within last 30 days, vehicle is not downshifting correctly when coming to a stop. Car does not actually downshift into 1st until after it is at a complete stop resulting in a lurch. No matter how smoothly the car is brought to a stop, the final downshift in auto mode doesn't occur until after reaching a stop. The problem does not start to happen until engine/car is warm as the first few complete stops when cold are 100% ok, then after warmed up it will occur every time thereafter. 4. when engaging drive or reverse, the vehicle will begin to accelerate slightly without pedal input such as when backing out of a parking space. Contacted dealer and dealer said no instructions from maker or tsb's yet and that transmission was new model and maker not sure what to expect. Told dealer I would drive the car for a few more weeks to see if situation improves. Did not take car in for check based on dealer comment that there was no instruction from Acura yet for a fix. Vehicle is now 3500 miles and issues 2, 3, 4 still occurring.

Transmission has extremely bad jerk from 2nd to 3rd gear. Also, transmission tends to make car accelerate on its own sometimes. Also, downshifting is too slow to make an effective pass on a highway. Horrible, unsafe feeling transmission.

- Austin, TX, USA

The contact owns a 2015 Acura Tlx. The contact stated that while driving approximately 50 mph, his foot was removed from the accelerator pedal. The vehicle decelerated to 40 mph and then rapidly accelerated without warning. The failure recurred while decelerating to 20 mph. The failure recurred on several occasions. The vehicle was not taken to the dealer or diagnosed. The manufacturer was not made aware of the failure. The approximate failure mileage was 10. Updated 4/20/15 the consumer stated when the vehicle was warm, it accelerated when down shifting and the RPM's would to 200-300. Updated 04/23/15
