Power Train Problems of Acura TLX - part 2

In 2022, my 2019 Acura Tlx a-spec received a warranty engine replacement due to a spun bearing. At that time, recall 23v-751 (connecting rod bearing defect) did not yet exist. Recently, the replacement engine developed a pronounced knocking/ticking noise at idle and during light acceleration. Multiple independent mechanics and an Acura service department confirmed the noise is abnormal and consistent with connecting rod bearing wear as described in the recall. Acura advised that my VIN is not included in the recall because the original engine was replaced. However, the replacement engine was supplied by Acura prior to the recall and may contain the same defective components. The dealership and Acura corporate did not inspect the internal components or verify whether the replacement engine used the revised bearing parts — they only referenced the VIN and engine number to deny recall eligibility. I currently have an open case with Acura, and the vehicle is scheduled for diagnostic inspection. I was informed that if the issue is determined to be related to recall 23v-751, diagnostic costs may be reimbursed, but there is no guarantee. This situation raises concern because my symptoms, timeline, and component failure are consistent with the known defect, yet my vehicle remains excluded from coverage. Given the safety implications of possible engine seizure or loss of power while driving, I am requesting that NHTSA review whether vehicles with Acura-supplied replacement engines should also fall under recall 23v-751. All service records and warranty history with Acura are available for review upon request.

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. These symptoms have continued intermittently since the recall repair. This appears to be a failure to properly diagnose and correct a known safety defect, resulting in repeated dangerous highway stalls and placing occupants at serious risk.

The awd components fail and turns the car into front wheel drive only. Yes it’s available. This puts mine and others after at risk due to expecting the car to accelerate at a full stop instead, it causes me to slowly accelerate <5 mph until the system recognizes it’s in fwd only. I fear that someone will rear end me expecting the car to go faster than it can in that moment. Yes, this has been reported to a reputable dealer and was told they could not create the issue once clears after turning car off and back on again. This car has not been inspected by anyone other than the local Acura dealership. There were no prior warnings other than when it was cuts out. This pops up on the dash and is effective immediately putting the car into a limp state. This is happening one a week and has been occurring for once the car hit ~40k miles.

Transfer case blew. Awd was not working.

Subject: complaint - safety recall failure (#23v75100) - engine failure summary: this is a complaint regarding a failure of the safety recall repair performed under recall #23v75100, which addressed a rod bearing issue that can cause engine failure. Details: 1. On or about April 4, 2024, southern Acura of newport news, va replaced the long block under recall #23v75100 after the original engine failed at approximately 130,810 miles. 2. On or about September 5, 2024, at approximately 173,722 miles, the replacement engine failed again. 3. The vehicle is currently located at hall Acura of virginia beach, va. , where the dealership has verified that the engine is seized and available for inspection. 4. The failure occurred while driving at approximately 70 mph in a construction zone, where there was no immediate shoulder or safe area to pull off. The sudden loss of power nearly caused a rear- end collision. 5. An independent service center, american pride - fort eustis in newport news, va. , also verified the problem and found metal shavings and bearing metal coming from the oil pan. 6. There were no warning lamps or alerts prior to the engine failure; all warning lights illuminated only after the loss of power.

Date of incident : August 31,2025 around 9pm on August 31, I was fixing to accelerate at a green light. I pressed the gas pedal, my car went up to 40 mph and then the engine failed. This is due to a recall on the bearing rods for 2015-2020 Acura Tlx. The incident occurred a month after financing the car. I don't have a warranty, so I opened up a case with the manufacturer to get help with the repair cost (which is 25,500 for a new engine block and 2 new cylinder heads). Unfortunately, Acura denied assistance. The car only has 68880 miles on it. The rod snapped and put a hole through my engine block. Shame on the manufacturer for denying assistance. I'm now stuck making payments on a car I cannot drive. Yes I have insurance, but it was not involved in an accident so I'm helpless there.

- the transfer case failed causing the awd system to stop working -it is a safety concern because you may lose control since no power is going to rear wheels, especially in inclement weather that we receive in the northeast. -yes the problem has been confirmed by dealership by putting car on lift and seeing that no power is being sent to the rear wheels. -there are no warning lights or any signs, you just hear a loud bang while driving and lost of traction while accelerating.

Transfer case has gone out. No longer getting power to the rear wheels as it is a awd car. Problem has not been checked by the dealer yet. There were no warning lights on the dashboard when it went out.

While performing a right turn, under normal acceleration a loud "pop/clunk" occurred. I immediately pulled into a parking lot as the vehicle was still able to drive. The vehicle runs as normal, no leaks of any kind present. Nothing visibly broken. Afterwards, I was able to determine with the vehicle suspended off of the ground, I am getting power only to the front wheels. Utilizing google, it's easy to see that this has become a massive issue on this particular model Tlx type s. The vehicle will be taken to Acura on Monday Aug 18th 2025 for diagnostics, but it's quite obvious that the splines on the transfercase at the transmission mounting location have sheared completely, thus making the vehicle front wheel drive powered only. Given my current situation, my hope is that Acura will honor the power train warranty as it is my understanding that both the transmission and the transfercase are required to be replaced in this instance. Acura also needs to issue an updated transmission/ transfercase combination and a recall because this is happening way to often and it's quite an expensive repair.

While driving my 2021 Acura Tlx type s, I began losing traction frequently during normal daily driving, especially when turning corners or accelerating from a stop sign or stop light. At first, I believed the issue was related to my tires, so I replaced them, but the same problem continued. After researching online, I discovered that transfer case failures are a known issue on these vehicles, affecting both new and used models. Currently, my vehicle is at the dealership, but they were unaware of this recurring transfer case problem and have no information about it. This is concerning because the failure of the transfer case directly affects traction and stability, creating a potential safety risk to myself and others on the road. It appears to be a systemic issue that Honda/Acura has not yet acknowledged.

The all wheel drive failed do to transfer case splines being sheered off between the transmission and transfer case. No warning lights are on to warn of the rear wheel tires not receiving power to them. I was not aware of this problem and this could have contributed to and accident, as I though the awd was working, but it wasn't.

Car shuts down randomly when accelerating from a stop or red light . All the mechanical lights come up on the dash.

Blown transfer case.

The all wheel drive (awd) system of the vehicle became partially inoperable after hearing a loud bang under normal vehicle acceleration some time in early 2025. The vehicle did not trigger or display any warnings stored in the onboard computer or on the dash display that the awd system had any faults or issues. Had this system failed during an emergency situation involving hazardous or dangerous driving conditions like snow, ice, heavy rain, it could have caused me to not have improved capable vehicle handling. The vehicle's ability to distribute power evenly to all 4 wheels was hindered and operating as front wheel drive only after the loud noise was observed. Additionally, transmission gear oil began leaking underneath the vehicle around the transmission casing. The issue has been reproduced, confirmed, and validated by technicians of a local Acura dealership. The dealership was approved to completely replace the following two components of the awd system under the manufacturer's 6 year / 60k mileage powertrain warranty: 1. Transmission 2. Transfer case - also known as power transfer unit or ptu.

The component that failed or malfunctioned was the transmission and transfer case on my 2022 Acura Tlx type s at 45k miles. I was driving the car on the street and the car was shaking and stuttering violently and at certain points it would not move requiring a tow. The problem was confirmed by the dealership to be the transmission. And inspected by the manufacturer (Acura) there were no warning, lights, messages or other symptoms prior to failure. They started appearing around 45,000 miles.

The contact owns a 2020 Acura Tlx. The contact stated that while operating the vehicle, the check engine warning light, the emission system failure, and electronic parking assist messages were displayed. Additionally, the awd feature had become inoperable, making the vehicle difficult to steer. The contact stated that the failure was intermittent. After disconnecting and reconnecting the negative battery terminal, the system was reset and the failure was corrected, but eventually reoccurred. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failures, but no assistance was offered. The failure mileage was unknown.

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 recall on 2015 Acura Tlx 6-cylinder transmission due to a bad wiring harness on their 9-speed transmission. I know mine is an 8-speed, but would it not use the same wiring harness with slight modifications? information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My car has suffered a well known issue in the 21-25 Acura Tlx community. At 71,000 miles my transfer case splines stripped also with the transmission splines. Resulting in me having to pay out of pocket to replace both the transmission and transfer case. I’m really hoping Acura does a recall for this issue. I really like this car and don’t want to have to replace them again. Like I mentioned before. I’m in a facebook Tlx group and people are constantly posting about theirs blowing.

Transfer case broken; no longer sending power to the rear wheels. Car loses traction when accelerating from a stop.

Transfer case documented as leaking on 3-22-2025/ 35,846 miles while doing regular oil change in my driveway. Brought to the dealership and they confirmed the transfer case needed to be replaced. If the transfer case went during operation, it could have lead to a dangerous situation with loss of power and control to the rear wheels. Problem was confirmed after dealership performed visual inspection. Component was not inspected by police, insurance, or others. No warning lamps, just accumulating liquid on the under-body panels and seeping from the gasket. The transfer case was replaced on 11apr2025 with the same part number: 29000-5yk-060. I asked if this would happen again since there was no revision to the part number, the dealership was unable to reply.

Awd system is no longer working. Every time I accelerate the front wheels are slipping and there are no warning lights or system failure messages. I believe this is a transfer case issue as there are now videos on youtube about Tlx type s's having this issue.

-transmission and transfer case failed, specifically the splines on the input shaft connecting the two, rendering the vehicle fwd instead of awd. Parts are not available to inspect as they were returned to dealer. -while the vehicle could still function in front wheel drive, the lack of awd could be a safety risk in poor weather or road conditions, especially given that the vehicle does not send an error code for this issue. -problem was reproduced by the dealer, who replaced both parts after a 2-month wait for parts. -there is zero indication that these components failed, no error codes or anything. The car also displays how much power is going to each wheel on the gauge cluster, and displays just as it did when everything worked. The problem can only be noticed when using awd, so many drivers may not know they have this issue. I experienced the traction control light blinking on hard acceleration due to front tire slip and understeer during turns, but beyond that there was no indication anything was wrong. -the dealer informed me this would be a $12,000 repair out of warranty, which I find unacceptable given that the car doesn't give any error codes. Many many people may not know their car is effected.

• transfer case failure, leading to transmission damage. • vehicle gives no indication of transfer case failure, in turn, giving the driver the impression that the vehicle is awd. Potential risk to safety as the failure happened under normal driving conditions, vehicle suddenly jolts, with loss of power. • problem addressed by dealership service dept. But not able to recreate, as this is a drivetrain fault. • vehicle and components inspected by dealership service dept. Only. • no indications or warning lights for tc failure. Awd system on dashboard indicates power is going to all four wheels when this is not the case.

Transfer case failure. Spline is stripped after 40k. Awd is disabled. Requires new transfer case and transmission.

While driving normal, I heard a pop sound coming from the bottom of the car which resulted in my awd not working. On acceleration the car would spin the front wheels and the traction light would light up. Took to dealer and they confirmed the transfer case and transmission failed and had to be replaced. The splines between both components had stripped.

The contact owns a 2015 Acura Tlx. The contact stated that while driving at undisclosed speeds, the vehicle hesitated while accelerating. The message to stop driving and have the vehicle serviced immediately was displayed. The vehicle was towed to the dealer, who diagnosed that the automatic transmission fluid (atf) warmer had failed. The dealer diagnosed the vehicle with other undisclosed failures due to the atf warmer failure. The vehicle was not repaired. The manufacturer was informed of the failures and opened a case. The failure mileage was approximately 77,000.

I was driving on the freeway for about 5 minutes and literally out of no where my car began to make a strange noise and then my engine light came on. Following that my car shut off and I immediately lost power I pulled over as best I can and turn my hazard on eventually the car died because I couldn’t get a tow out fast enough and I’ve had it sitting at a shop ever since this incident. . Tell.

The vehicles awd system has prematurely failed as confirmed by the car dealership Acura of pembroke pines that I have taken it to. The lack of traction to the rear wheels causes excessive torque steering and constant engaging of the vsa system if the road is even remotely wet and the vehicle is under anything more than mid level acceleration. There are several Acura Tlx type-s trim vehicles that are being reported to have this common issue and Acura / Honda is keeping this quiet and replacing the prematurely failing transmission and transfer cases with what I fear are the same faulty parts instead of properly developing a revised updated part that will properly correct the issue. An awd system is meant to give the driver confidence on the road and premature failure under slippery road conditions be it rain or snow is putting peoples lives in jeopardy.

Went to accelerate and heard loud bang. Transfer case shaft snapped internally into transmission. Transfer case and transmission assembly both replaced under warranty. Will happen again in another 40-50k miles.

Transfer case failure with no warnings or symptoms of problem prior to failure. This is a safety issue as my car was only operating in front wheel drive due to the transfer case failure. This is a common issue that needs to be investigated.

The all-wheel-drive stops working and the car becomes front wheel drive only. There are no warning lights on. The only way you could tell is to jack the car up with all four wheels off the ground and put it in drive to see if all four wheels are spinning. Also the driveshaft should be turning out of the transfer case. The the roads are wet or with snow the front wheels brake free very easy and the traction light comes on, which is also sign. I took it to the dealer and they verified the issue. They said it needs a new transmission and transfer case because the splines on the output shift of the transmission strip out and also damage the splines on input shaft of the transfer case.

The transfer case splines between the transfer case are stripping causing the car to lose power in the rear wheels forever. This is a safety hazard as now the wheels lose traction and massive oversteer. This is dangerous in many conditions especially rain as turns are much more prone to sliding and losing traction. It was confirmed at the dealer and is a known issue in the Acura car community. The only way to diagnose the problem is putting it on the left and putting the car in drive to see if the all wheel drive system is working (all 4 wheels spinning). This is a scary problem for owners as no codes are generated since there is no sensor to catch this . The cars other system were also designed with the intention of the car being all wheel drive so this could lead other systems to fail causing a likely accident or collision.

Transmission harsh and delayed gear engagement, sometimes it won’t shift unless it’s done manually, few times it didn’t shift even though I shifted manually, I had to increase engine speed to about 5000 rpm so it shifts, transmission goes into neutral when trying to to accelerate while it’s in drive and intermittent vibration caused by hydraulic circuit pressure issues, I’ve had the vehicle since it had 7900 miles and all these issues been present in the car since then, the car now have 29000 miles and it’s only getting worse. These issues have been reported by a lot of Honda/Acura vehicles owner with the 9 speed transmission.
