Engine And Engine Cooling Problems of Acura TLX - part 1

- the engine ceased while the car was moving, causing (a) a sudden stop (b) engine stopping and the car becoming inoperable in the middle of a street. - there were no injuries because the failure happened at low speed. The same failure on an expressway would be a major safety concern since the car came to sudden stop. - the failed engine was inspected by an authorized Acura dealer. Cause identified as cylinder 2 rod bearing failure. - there was a slight knocking sound right before the incident occured - the car was driving fine before the incident. There were no warning indicators. - the engine (short block) was replaced previously on the same car due to a knocking sound.

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. Injuries: no crash: no fire: no speed at time of incident: idle.

I drive a 2021 Acura Tlx type s around 85k miles. I heard a loud clank when I was driving one day, and I loss traction. When I was accelerating I was losing traction and it seem like I lost power while I was moving as well. It seems like I'm driving front wheel drive. I let me foot of the gas and it seems like it's back to normal sh-awd. I hope this gets looked into and fixed soon.

Acura Tlx 2017, with only 112,000 miles. On [xxx], while the consumer was driving, the vehicle caught on fire. The consumer saw what appeared to be smoke coming from under the hood. The consumer stopped the vehicle immediately at a 4-way intersection, put it in park, and turned it off. The hood latch was open. When the consumer opened the hood, the engine compartment was on fire, and the car was engulfed in fire within seconds. Fire department and police depratment arrived at the scene. The car was deemed a total loss, and the fire was determined to have started in the engine compartment. In may 2024, Acura stated that the connecting rod bearing needed replacement and that it was covered under the recall. However, 6 months after replacement, in October 2024, the knocking noise returned. The vehicle was brought to the Acura dealership, which noted at that time that the engine needed to be replaced, but the repair was denied under the recall this time. As required and recommended by the Acura dealership, as well as by the recall, which noted safety risks, the consumer moved forward with having the engine replaced by the Acura dealership, and the cosnsumer paid out of pocket. The vehicle was at the Acura dealership in westwood for service from October 2024 until February 2025. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

- the engine system failed and it is available for inspection -while driving on the highway at normal traffic speed, my vehicle suddenly developed a loud knocking noise and the check engine light lit up. Within moments, the engine lost power and became inoperable, leaving me unable to continue driving while being 300 miles away from home. This incident occurred at about 5-6am, having to maneuver through traffic before the sunrise. This created a serious safety risk because surrounding vehicles were traveling at full speed increasing the risk of collision. There were no warning signs of this failure and I was unfortunately stranded on the highway in an unfamiliar town for hours with minors in the vehicle. -yes, the vehicle was towed to a local dealeriship, hahira automotive services, where the engine failure occurred and they confirmed that they were unable to start the car and the knocking sound was indicative of engine failure. I towed the car to an Acura dealership local to my home and they confirmed the same vehicle condition and that a takedown is required to fully inspect the engine. -the engine has not been inspected by anyone only the vehicle condition -there were no warning signs of engine failure prior to the incident.

My 2017 Acura Tlx stalled dangerously on the highway due to an unexpected fuel delivery failure, creating an immediate traffic hazard. Hiley Acura of fort worth diagnosed the vehicle with code p0087 (low fuel rail pressure) and confirmed it needs a new low-pressure fuel pump assembly for $1,540. 62. They also pulled code p0430 (catalyst system efficiency) showing my front catalytic converter has failed, costing $2,461. 77. The low-pressure fuel pump failure starved the engine of fuel, causing the highway stall. This fueling issue directly overheated and destroyed the catalytic converter substrate. This pump failure is the core subject of the oliver v. Honda class action lawsuit. Honda previously issued a temporary corporate software update on my vehicle that deliberately altered how the computer reads errors, masking the physical fuel pump defect. This software update is the exact reason my car currently shows no open recalls on standard databases, despite still containing the defective, unreplaced factory hardware. This temporary software fix has now failed, resulting in a dangerous highway stall, and Honda is using the software-cleared VIN status to deny safety coverage.

On 07/01/2026, at approximately 8:00 am, during steady acceleration, flashing of mil with loss of power presented northbound after merging from 235 west bound to I-135 north bound near park city, KS. Particularly dangerous resulting in near rear end collision. Upon taking nearest exit ramp, attached bluedriver . Obd ii reader, and fault code p0303 - cylinder 3 misfire and u0401-68 pgm-fi/ecm/pcm system event code was logged, with multiple warning indicators that safety system, awd, brake, and other systems were disabled. Note, vehicle has had TSB 20-053 update w/ flash of pgm-fi which did not resolve the fault, fault associated with hot and humid climates or period of rain fall, apparent water vapor, condensate build up in intercooler. For Honda accord and Acura rdx w/ 4 cylinder 2. 0 tdgi engine TSB includes redesigned intercooler replacement, that is not available for Tlx 21-25 which is currently out of production. This has occurred previously during humid and hot weather, but no intermittent flashing mil does not store code. Thankful in this instance p0303 and u0401-68 code is stored, and scheduling service at dealership to diagnose misfire.

The contact owns a 2019 Acura Tlx. The contact received notification of NHTSA campaign number: 23v751000 (engine and engine cooling). The contact stated that while driving approximately 55 mph, the vehicle lost power and the steering wheel failed to responded as needed. The vehicle stalled in the middle of the road. The vehicle was restarted but stalled immediately. The contact inspected the vehicle but found no fault. The vehicle was towed to an independent mechanic where it was diagnosed that the rod bearing had failed and the engine needed to be replaced. The vehicle was not repaired. The vehicle was then towed to a dealer where it was diagnosed that the rod bearing had failed and that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 120,000.

I have this car 2017 Acura Tlx v6 shawd from Acura dealership 3months already. I hear little knocking sound from my bottom block.

Driving car and suddenly all the lights on the dash light up and car goes into “limp” mode. Upon pulling over turning car off and turning back on lights are all still lit up. Plug car into obd2 scanner and car is showing code p0087 low fuel rail pressure. This is extremely dangerous as the car will randomly do this and will go into limp mode which can easily cause me to get into an accident. No active recalls on this but I’m seeing this is a common issue with these Acura Tlx models. Why hasn’t this issue been addressed yet Acura?! for reference I drive a 2018 Acura Tlx base model 2. 4 cylinder.

I drive a 2021 Acura Tlx 2. 0 l turbo 4 cylinder. I was driving to work on [xxx] on a busy street in boyle heights, CA. When all of sudden I get a warning indicator “engine temp is high do not drive”. Pulled over immediately. Good thing I was in the far right lane and was able to pull over and not stall or get rear ended by another vehicle behind me. There were no warning, symptoms and indicators of the engine's overheating. My vehicle has been in great condition prior with no major or minor issues with my vehicle. We took it to two dealerships for diagnostics. The head gasket blown, empty coolant reservoir, cracked engine block, and other parts of the engine were affected. What if I was on a highway and the car stalled. I could’ve been seriously injured or seriously injured someone else on the road. Acura corporate is aware of our situation and refuse to own their engine safety defects. They want us to pay out of pocket to repair our vehicle. My car is 5 years old there is no way out of nowhere my vehicle should have this type of engine issues. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I bought my 2018 Acura Tlx a-spec v6 in Nov. 2021, certified pre-owned from an Acura dealer. It had warranty through 100k miles. At just under 70k miles, around mid-2023 I believe, the engine seized and would not start. Warranty covered engine replacement. This was just around the time of the 3. 6l v6 engine recall. I waited on the recall because the engine was brand new at that point. A year or so later, deal did inspect the engine for recall, but determined it was not part of the recall. Come current to late April 2026, just before engine #2 hit 70k miles (total miles on car ~139,000), engine has seized again. Driving on freeway and car went into limp mode, thankfully close to home and made it safely. Had car towed next day to mechanic who sent a video of the knocking noise (can send video if requested; unable to upload here) and refused to work on it. He later drove the car down the block and that is when engine completely failed; no longer would turn on. Towed home, towed to dealer a week ½ later when they had opening. Dealer performed diagnostic and confirmed crankshaft seized. However, now, well past warranty coverage. I called Acura customer relations and opened a case; they will only cover "half" of the engine replacement, at a cost of $13,817 to me. My car is less than 10 years old, less than 150k miles overall and should not need engine #3. Will same issue happen after another 70k miles? Acura refuses to acknowledge and take care of it 100%.

My car broke down on 04/05/2026 on the highway at a light with on coming traffic. I took it to express oil change 04/06/2026 they told me my car need a crankshaft so I proceeded to get more information and come to find out it was a recall on the crankshafts on my car. This is the second recall I have had done to my car the first recall was for the motor. This second one is for the crankshaft recall number- ch7. I was told by Acura a month and a half after them having my car that the serial number on my motor doesn’t fall up under the recall, but my VIN number does and there saying they can not fix my car. Only had this motor for 2 or 3 years from the first recall it had on it.

I am formally requesting a neutral third-party arbitration review under the magnuson-moss warranty act to compel american Honda motor CO. To provide a permanent mechanical remedy—specifically, the sourcing and installation of a brand-new, redesigned engine assembly (engine #four)— this vehicle frame is now on its third engine block. Car was bought 11/30/2024. At grubbs Acura, fuel pump safety recall that involves flashing/re-calibrating the engine control unit (fi-ecu) software was done. Just a few weeks after new fuel pump, the vehicle displayed sudden stalling symptoms. The engine suffered a terminal, catastrophic internal collapse. The vehicle was towed to grubbs Acura where corporate Honda directed a forced out-of-pocket internal engine teardown. The physical teardown explicitly confirmed a catastrophic connecting rod bearing failure (spun bearing) identical to the structural manufacturing flaws currently under active federal investigation by the NHTSA under preliminary evaluation pe25008 / rq24-025. Corporate Honda subsequently issued a verbal agreement to fully reimburse my out-of-pocket teardown fees. Because a manufacturer will never fund diagnostic labor if evidence of owner fault is present, this corporate reimbursement serves as formal validation that no owner maintenance neglect occurred, and that the engine died exclusively from an inherent component defect. Gunn Acura (san antonio, TX) confirmed with my VIN, that engine #3 was a warranty/dealer-installed replacement unit at 22,000 miles. It failed after less than 40,000 miles of total operation. A professionally manufactured and dealer-installed engine is reasonably expected to last well beyond 40,000 miles. The manufacturer network cannot utilize arbitrary part-ownership rules or uncooperative, fragmented dealer communications. The original factory-installed engine and the dealer-installed replacement engine both suffered identical connecting rod bearing failures.

My 2017 Acura was involved in a low-speed collision where it failed to stop in a timely manner, resulting in a total loss declaration. This vehicle had open safety recalls (including the fuel pump/rod bearing issues) that remained unrepaired for over 1. 5 years. Despite multiple inquiries, the manufacturer failed to provide a repair timeline or remedy. I believe these unresolved defects directly contributed to the braking failure and subsequent safety incident.

I have a 2016 Acura Tlx 3. 5l j35y6 awd that initially had the safety recall xg1 and the engine was replaced at roughly 140k miles, 40k miles later the replacement engine suffered the same problem, and I am aware that I am not the only person this has happened to as there is currently a NHTSA investigation pe25008 that is related to these replacement engines failing. I have pushed the dealership for full replacement as this is not right and they have not budged as to the replacement. There were no warning lamps as to before the failure. The engine just threw me into limp mode.

The emergency brake system continues to come on and read all the type of stuff on the screen, as well as the lkas keeps coming on the screen showing problems and when it does, the transmission or engines stalls a little and slows up and speed down on its on.

This vehicle was sold to me on July 18, 2025 with campaign ch7 open and unperformed. The dealer's disclosure form falsely stated that I had been informed of all recalls with the vehicle. No specific mention of campaign ch7 was ever made. Separately, Acura manufacturer records (evrm/techline) confirm that this vehicle's original engine was previously replaced under warranty following a seizure (defect code: seized) — directly related to the defect type covered by the ch7 recall. The replacement engine subsequently seized approximately eight months after I purchased the vehicle. I am requesting NHTSA investigate whether the open campaign ch7 recall contributed to the engine failure, and whether fsl motors' practice of selling vehicles with open recalls while falsely certifying recall disclosure warrants further review.

Vehicle displays two warnings under normal usage. First warning is emissions system issue and second is brake system failure. The vehicle runs completely normal and operational, however these two warnings flash on the vehicle. The parking brake indicator also flashes. Vehicle has been to dealership/shop for multiple repairs; around 3-4 repairs within two months with no resolve for the same warning/issue.

The contact owns a 2015 Acura Tlx. The contact received notification of NHTSA campaign number: 23v751000 (engine and engine cooling). The dealer was contacted several times for the recall repair; however, the dealer informed the contact that the part to do the recall repair was not yet available. The contact stated while driving 45-50 mph, the vehicle lost motive power. The contact was able to veer to the shoulder of the road. The vehicle failed to restart and was towed to firestone, where it was diagnosed and determined that the engine had seized. The vehicle was not repaired and was towed to the residence. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not notified of the failure. The failure mileage was approximately 99,000.

Vehicle has been recalled for a speed sensor issue that still persists. Recall repair was not properly executed. Vehicle engine still randomly shuts off while in idle at stoplights and during travel. Engine won’t start at this point.

Pe 25008 the engine knock started on 12/22/25. Motorcars Acura recommended get a case number & have the 2020 Tlx towed in for a diagnostic. Online case # xxx towed to motorcars on 12/23/25. Talked to michelle with customer relations & she was going to call motorcars for info. Motorcars, without my permission, pulled the oil pan & inspected the bearings. #6 rod bearing failed. On 1/15/26, michelle with customer relations told me that they will not offer reimbursement to repair. I told motorcars to do the repair on 1/15/26. Picked up the car on 1/21/26 info & pictures attached. I told michelle I hope you reconsider reimbursing me for the repairs. As I told michelle, I am very loyal to Acura as I own (4) Acura’s. Now two of them have engine issue. The 2020 Tlx rod bearing issue that was not included in the recall & my 2012 mdx with the 3. 7 oil consumption issues. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Recall performed on 2020 Acura Tlx 3. 5 for rod bearing recall. Crankshaft and bearings were replaced. 24000 miles later, the engine spun a bearing again with all the new internals. All maintenance records were supplied when the car was brought in. Acura is wanting me to pay 40% of the cost for a short block.

While braking and attempting a left turn at an intersection, my vehicle completely shut down with no braking or steering control. Fortunately there were no damages and the vehicle started up again and I was able to clear the intersection. I took the vehicle to an authorized dealer for repair. They indicated that this was a known issue and they were familiar with it. They installed a battery sensor and did brake work as they said there was air in the system. I paid for the repair and approximately a month later, while slowing down for a red signal, the same thing occurred, only this time my vehicle impacted another vehicle, causing damage to both vehicles. I had my vehicle towed to the shop that did the initial repair, but they said they could not find any codes that would indicate that their repairs were faulty.

My 2015 Acura Tlx’s engine has internal issues with rod bearings, as mentioned in other recalls of the same year, yet my VIN does not fall within the recall.

The contact owned a 2019 Acura Tlx. The contact stated that while driving at approximately 65 mph the vehicle was losing forward velocity and the steering was pulling slightly to the right. The contact stated that the vehicle suddenly and violently turned to the right. The contact was not aware of any warning lights. The contact was unable to counter turn and the vehicle crashed into the guard rail on the right front bumper. The contact stated that the force of the crash shot his vehicle to the left, crossed two lanes of traffic and crashed into the guard rail on the left side of the highway. The contact stated that this crash with the guardrail deployed the drivers side curtain air bag. The contact stated that the force of the crash shot the vehicle to the right and he drove off of the roadway down a slight embankment. The contact was able to stop and exit the vehicle. The contact saw that front bumper had sheared off and that the right fender and wheel well were crushed. The contact stated that the he could see the right tire suspension and control arms were exposed and fractured. The contact stated that the damage of the left side of the vehicle was not as severe. The contact stated that the passenger side curtain air bag had also deployed. The contact stated that the police were on scene and wrote a report. The contact stated that he was transported by ambulance to the er. The contact stated that he had bruises and cuts on his right temple and check and swelling, cuts and bruises on the left cheek and left temple and forehead. The contact stated he was released after treatment. The contact stated that the vehicle had been towed to an impound lot. The manufacturer was not informed of the failure. The contact had received recall notice for NHTSA campaign number: 23v751000 (engine and engine cooling) and related the failure to the recall. The failure mileage was approximately 48,000.

The vehicle experienced vibration symptoms and stalled on the road. The day before it stalled, there were rattling noises which prompted me to take the car to the dealership the next day. I had just received the letter about the recall so I knew it was likely related. The car was towed to the Acura dealership but the dealership denied recall coverage, stating the engine number did not match the recall list. During the discovery process, it was later discovered that the engine had been swapped by the dealership in 2018 — a fact that was not disclosed to me at the time of my purchase. The installed engine still falls within the recall defect interval of 2015-2020 but they are resistant to repair. Upon initial inspection of the vehicle, the dealership found metal shavings in the oil indicating internal engine damage. The manufacture requested my oil change records suggesting that this was my fault. I presented the oil change receipts but they still refused recall coverage and the dealership requested approximately $5,000 for diagnostics, if determined my fault. If it is determined that the defect damaged the engine, they will cover the 5k. After several weeks of inspection and going through the manufacture recall process, the dealership determined the recall issue applies my car. However, due to the engine number not on the “list” they are denying my recall coverage. They are seeking $25k for service repairs. After almost 2 months of back and forth, I have been misled and misinformed. I am struggling to get my car repaired under recall.

49,622 mark on my 2020 Acura Tlx awd… auto stop was enabled, car was at stoplight, engine attempted to re-engage but did not and car went into “neutral”… and the lights stayed on. I immediately turned on blinkers to avoid crash and and attempted to re start car, I shifted into park, shut down car and re-started it successfully. I am seeking repair or disablement of the auto stop system, this is a safety hazard to myself and my family as well as others who had to go around while the issue was being troubleshooted. This appears to be related to investigation:ea25004.

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.

On or about October 21–22, 2025, I brought my 2020 Acura Tlx (brown, 99,000 miles, VIN [xxx] ) to goodson Acura of dallas for a recall repair related to engine concerns. The vehicle was returned to me on October 24, 2025. Shortly afterward, the car began to lag and hesitate while accelerating. On November 3, 2025, while driving to a doctor’s appointment on the bypass bridge in morning traffic, the vehicle suddenly stalled and lost power completely. This created a dangerous situation in active traffic. I recently underwent surgery following a serious burn injury, so limited mobility made this stall especially hazardous. After restarting the engine, multiple adas and system-fault warnings appeared. I contacted goodson Acura and was advised to bring the vehicle in. Upon arrival, the service advisor confirmed the warning lights but required a $205 diagnostic fee despite the recall work. Acura client relations opened case no. Xxx and advised the charge should not apply if related to the recall. After waiting several hours, I was told the battery had died and that front camera/adas systems were returning codes. This stall occurred less than two weeks after recall repair and could easily have caused a serious crash or injury. I am requesting a full investigation into the recall repair, the stalling issue, and any related safety defects. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My engine has been replaced under warranty for connecting rod bearings failing before the recall 23v-751 existed. 40,000 miles later it failed again. I have paper work and other information available upon request. The vehicle is currently on it's third short block replaced by Acura. No cel or anything prior to when the knocking started.

The contact owns a 2016 Acura Tlx. The contact received notification of NHTSA campaign number: 23v751000 (engine and engine cooling). The vehicle was taken to the dealer; however, the contact was unsure if the vehicle was inspected. The contact stated that the dealer had not provided a status update regarding the vehicle or the repair. In addition, the contact stated that the vehicle had been at the dealer for several days. The contact stated that it was expensive paying out of pocket for a loaner vehicle while waiting for the vehicle to be repaired due to the recall. The manufacturer was not made aware of the issue. The contact had not experienced a failure.

The contact called on behalf of the owner of a 2015 Acura Tlx. The contact's son received notification of NHTSA campaign number: 23v751000 (engine and engine cooling), and the vehicle was taken to the dealer; however, the dealer had cancelled all three recall repair appointments because a technician was not available to repair the vehicle. Most recently, the contact's son was informed that the vehicle needed to be inspected to determine whether the recall repair was needed. The manufacturer was not made aware of the issue. The vehicle owner had not experienced a failure.

My 2021 Tlx type s front wheels started to spin upon acceleration at 44k miles. I immediately scheduled an appt for the dealership. Was informed I needed a new transfer case unit, as the splines were shredded. With this, I also had to replace the transmission. All replaced and picked up today 12/2/2025.
