Recalls on the transmission
“The transmission is slow, hesitant and jerky in models with the v6 engine. I almost got into a major car crash due to the transmission’s very hesitant behavior. Other owners have experienced this slow and clunky transmission behavior, after looking in many online forums. The transmission has been way since the vehicle first came out but Honda still has not addressed the issue with the 9 speed transmission.”
Owner complaint, filed Jun 8, 2024
“Upon braking, when coming to a full stop, the transmission (ZF 9-speed automatic) makes a very hard downshift into 1st gear and causes the car to lurch forward. This issue appears to be worsening over time. The car is becoming more and more difficult and dangerous to drive due to this issue. The car was very recently brought into an Acura dealership (DCH Montclair Acura) to address this issue.”

I am reporting a catastrophic safety defect and a failure of a federal recall remedy on my 2015 Acura TLX. My vehicle was previously identified as part of the connecting rod bearing recall (NHTSA Campaign Number: 23V751000). The dealership performed the official recall inspection/remedy in February 2026. However, in September 2026, the engine suddenly developed a loud, metallic knocking sound coming directly from the motor. A metallic knock is the primary warning sign of imminent rod bearing failure, which poses a severe safety risk of sudden engine seizure and stalling while driving at highway speeds. I contacted Acura Customer Service to report that the recall remedy failed and that the vehicle is unsafe to operate. Acura corporate has completely denied my claim and refused to take corrective action, despite this being a direct, unmitigated failure of the recalled component.

While driving my 2015 Acura TLX, warning lights illuminate and the vehicle unexpectedly shifts into neutral while the vehicle is moving. When this occurs, the vehicle loses the ability to accelerate normally, creating a serious safety concern in traffic. These symptoms appear consistent with the condition addressed by Acura recall KC2 (NHTSA Recall 16V-640), involving the transmission wire harness/connection and transmission control system. The recall describes a condition in which the transmission can unexpectedly shift into neutral while driving. My VIN is not coming up under recall yet my vehicle has done this same thing multiple times over the past few months. I need my VIN added to recall list so this serious issue can be repaired under recall by Acura.

The 2015 1st generation Acura TLX is affected by a defective torque sensor inside the steering gearbox that malfunctions sending error codes displaying as LKAS, ESP, EPB, ACC, Driver mitigation control, etc. these driver assisted technologies are dangerous when faulty. a fault code triggered in the driver assist system tech causes the vehicle to lose power steering under power and at speed causing an unsafe operation of the vehicle that can result in death. Honda motor corp is aware of this because they extend the warrantee for this part to be replaced. Honda issued a superseding memo to cover the cost of repairs between 80-100 percent of the repair. the original TB (tech Bulletin) 15-056 was for 2013-14 Honda Accord, however the 2015 Acura TLX shares the design of that vehicle and supplied the parts for the first generation Acura TLX. the revision classifies the gearbox as no longer a controlled part, a replacement must be ordered when hard codes are repeating 53-02, 53-02. I have spoken to Honda and they are denying this issue is a recallable issue. it has to be recalled and if research is conducted I am sure that it will be seen to have caused collisions on the roadway, I have had several near miss incidents and my vehicle has very low miles to be affected by an issue like this and the car has never been hit.

The vehicle is experiencing extensive factory paint failure and clear-coat delamination on the roof, around the rear windshield, C-pillars, and upper door frames. The condition began approximately 12 months ago around the rear windshield and has progressively spread to multiple upper body panels despite normal ownership and maintenance. The paint is peeling in large sections, exposing the underlying paint layers. Research indicates Acura previously acknowledged a similar paint adhesion defect affecting certain 2015 Acura TLX vehicles around the rear windshield and issued a warranty extension for some vehicles. Although my vehicle may not have been included in that program, the failure pattern appears substantially similar. The vehicle has not been involved in any collision affecting these areas, and the paint appears to be the original factory finish. The condition continues to worsen over time. The vehicle is available for inspection upon request. Acura Client Relations has been contacted, and a case has been opened requesting inspection and review.

The vehicle is throwing a steering code of LSAK. The steering is being compromised as the vehicle cannot determine if it is being steered correctly or not. After researching this code, I have seen hundreds of other people so far complaining about the same code for this year, make and model. One person had stated that his steering stopped mid way on his drive. I looked up the prices of correcting this issue and it ranges anywhere form 1800.00 to 2000 .00. My vehicle only has 65,000 miles on it and this is a potentially very dangerous situation. With the hundreds of customers that I have seen so far that are complaining of the same issue, I do not feel that this should be the customers responsibility to fix but rather a recall or at the very least a class action lawsuit if the dealer will not correct this potentially very dangerous issue.

The fuel delivery system, specifically the fuel pump, has malfunctioned. This vehicle is subject to a fuel pump safety recall, which was reportedly repaired in 2022; however, the vehicle continues to experience the same failure symptoms and is available for inspection upon request. The vehicle has stalled multiple times at highway speeds, resulting in sudden loss of power while driving and creating an immediate risk of collision with surrounding traffic. My family was in the vehicle during these incidents, significantly increasing the risk of serious injury or death. The problem has been reproduced multiple times, including after the vehicle was taken to an authorized Acura dealership. During the most recent visit, diagnostic trouble codes were cleared, but the recalled fuel pump was not repaired or replaced. After being released by the dealership, the vehicle stalled again under similar driving conditions. The vehicle was inspected by the dealership, but no corrective repair was performed beyond clearing codes. The manufacturer has not yet properly remedied the recurring safety defect. Prior to stalling, the vehicle exhibited intermittent hesitation, loss of power, and engine shutdown. Warning indicators and fault codes were present at times and were cleared by the dealership without resolving the underlying issue.

Atleast 5-10 different messages displayed and all sorts of warning lights showed up. The vehicle then shifted to Neutral (N) and flashed N repeatedly. I was able to pull off the road safely but I was unable to put the car in Park, Drive, Reverse. I was only able to use the parking brake and shut the car off. I tried turning the vehicle on twice and both times it was in Neutral. After letting the car sit for 30 minutes I tried starting it again and at that point the vehicle was in park and only displayed approximately 3 messages; I was able to drive the vehicle again. I’ve owned this vehicle for 10 years and it’s gone into Neutral once before. I’ve also had the vehicle display multiple messages while driving. The vehicle was drivable with the few messages and after a few days the messages went away and functioned normally.

My 17 year old son drove across town about 6-7 miles from home, on a back road. Out of nowhere, his 2015 TLX started to make a sound like knocking or thumping. Just moments afterwards, most if not all of the engine warning lamps illuminated at once.. He pulled off as best he could there was a loss of power and massive amounts of steam pouring out from the under hood. At sunrise I went to the car to wait for AAA I was astonished at the mess on the pavement under and around the car, and even more surprised to hear from my mechanic told that the engine had seized. I remember my mechanic using the word "warped" to describe it to me. I had him replace the engine, as I was I unaware of the recall at that time. It was not inspected by anyone besides my mechanic.

Connecting rod bearing seizure leading to engine failure on the TLX 2018 engine 3.5 liter V6 engine. Our 2015 TLX Acura we had to replace our engine because of the connecting rod bearing seizure and our extended warranty covered it around 2020. In 2023 the second the Acura motor which is TLX 2018 engine 3.5 liter V6 failed due to same problem, connecting rod bearing seizure. Acura will not do a recall on that motor. They say because its was manufacture in a different warehouse its not covered or a problem. I know there are other people struggling with the same issues on the 2018 engine. I know there are other investigations on this motor.

Hi, I have had a couple instances where the engine revved up between gears. Both times, I remember it happening rather soon after starting off from a stop sign. I didn't pay it much mind, but noted it. Just today, I asked my wife ([XXX]) whether she had noticed anything with the car. I purposely didn't ask any leading questions. She said a few times it would jump instead of smoothly going to the next gear. In Seaside, OR, I started to pull out onto [XXX], planning to take a right and head south bound. There was a Southbound car approaching from the North, but I had plenty of time to pull out and get up to speed. Immediately after starting out, the car popped into neutral and the RPMs raced. I already had some momentum and was on the highway, so I couldn't brake, and because it went into neutral, I hadn't finalized my turn so I was still pointing SE. As the car quickly approached, all I could do was use what little momentum I had and continue into the Northbound lane so the oncoming car could pass. Because of the slight slope to the Northbound shoulder, I was able to slowly come to a stop. I put the car in Park, turned it off, then back on, and everything came back to normal. I cannot begin to express how scared I was. I have lost brakes before in a car, but I know to use the emergency brake. I was completely dumbfounded as to how to react. Had there been oncoming traffic, it would have been an awful accident. Why is there no recall on this? I researched on Google and found a

The car is constantly throwing codes for faulty emissions system problem and parking brake problem but the car runs fine. The dealership will not do anything unless I pay them a fee to diagnose it and then they suggest replacing the catalytic converter even though it’s very likely a faulty fuel hose or faulty sensor. This needs to be recalled and fixed immediately

Three years ago, the car started stalling at traffic lights coming to a stop battery was replaced and the problem went away. A new battery was installed a few months ago and in the last week the same stalling situation has occurred three times. Acura says there’s a software update, and when the car was brought in for the recall on the connecting rod bearings, they said they refreshed the software pertaining to this issue, but obviously it does not work others say that it has to do with the idle stop and that disabling it resolves this problem. I haven’t tested this yet, but I am going to, but it’s an ongoing problem. That’s a major safety concern and could cause a fatal accident.

While driving on the freeway/highway my vehicle went into limp mode and shifted into neutral. My vehicle would not allow me to shift gears and the car would not let me accelerate anymore. I had to think quickly and move out from upcoming traffic. With little speed I had on my vehicle I could only shut down the car and wait for a tow truck. This happened to me twice in 2020 and the mechanics could not find any issue or replicate what had happened. They said this was a software issue. I was still scared to drive my car thinking this would happen again. Then 2 years after ( 2024) again this happened and it was when I was on the freeway. Luckily I was on the left side and was able to stop on the shoulder but stressing out and still traumatized from what occurred 2 years ago. I took it to the dealer and same thing they could not replicate the issue and did re programmed the software. I believe this car is not safe to drive at all knowing this can happen again and again at random times. The attached document is what the dealer gave me stating this remedy was done to the vehicle. This need to be investigated.

Unable to get an appointment to address the Connecting Rod Bearing recall until May 12, 2025 which is the earliest available. Apparently, Acura is not providing their dealers with enough required tools and parts to do more than 5-6 recall appointments per week with some weeks having no parts available. Given that the engine can actually seize if this issue is present, being asked to wait until May 2025 is simply I unacceptable and does not meet your comment on your website about effecting the repairs in a “timely manner”. I have contacted 4 different dealers and all report the same issues with lack of tools and parts. Acura needs to step up acquisition or manufacturing of tools and parts.

The transmission is slow, hesitant and jerky in models with the v6 engine. I almost got into a major car crash due to the transmission’s very hesitant behavior. Other owners have experienced this slow and clunky transmission behavior, after looking in many online forums. The transmission has been way since the vehicle first came out but Honda still has not addressed the issue with the 9 speed transmission. This poses a huge safety risk to me and all other owners.

I received notice of a recall on my 2015 Acura TLX in January 2024. The notice indicated parts were not available for repair and I would receive further notice when parts became available in early spring. I heard nothing by May 1 so called the dealer. They said parts are coming in slowly and the first available appointment they could give me for repair would be in AUGUST. I am planning to transfer this car to a family member in June, so this is unacceptable. It also means that I continue to be exposed to any safety problems that arise.

2015 Acura TLX: questions buyers ask

Is the 2015 Acura TLX a good car?

Going by the federal record, it is one of the TLX years to avoid: owners filed 344 complaints, 4.2 times as many as a typical TLX year. The most common complaint is about the transmission (34%). In NHTSA crash tests it scored 5 stars overall.

What is the most common problem with the 2015 Acura TLX?

The transmission: 118 of the 344 complaints (34%) are about it. Owners most often say it jerks, lurches or bucks (40%), shifts hard, late or not at all (23%) and hesitates before moving or accelerating (22%). The typical report comes at 4,000 miles.

How many recalls does the 2015 Acura TLX have?

6 safety recalls on file with NHTSA, the most recent filed Dec 18, 2023. The largest, 23V858000, covered 2,490,460 vehicles. Recall repairs are free at a dealer; whether a specific car still has one open depends on its VIN.

At what mileage do 2015 Acura TLX problems start?

Half of the complaints that record an odometer reading came in before 17,000 miles. For the transmission the midpoint is 4,000 miles.

Has NHTSA investigated the 2015 Acura TLX?

Yes, 2 times. The latest, EA25004 ("No Restart After Auto Start/Stop Engages"), was opened Mar 26, 2025 and is still open.

Are there service bulletins for the 2015 Acura TLX?

The manufacturer filed 430 technical service bulletins and other notices for it with NHTSA, most of them about the electrical system (84), the transmission (69) and the engine (45). They include a warranty extension, Defect Code 6T6,, filed Jun 15, 2022. A bulletin is a repair instruction to dealers, not a recall: the fix is usually free only under warranty.

Reading this record

Complaint volume is well above typical for a single model year.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.

Most recent recall on file: Dec 18, 2023. Source: NHTSA Office of Defects Investigation.
