Engine reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

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 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%.

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.

The engine has been making rattling noises when you start the vehicle from a long rest, mostly over night, since it has about 24k miles on it, when I purchased it used. I noticed it some time after I purchased it. Took it to Honda dealer in Hickory, NC, but they couldn't hear it. Later also took it to Acura dealer in Charlotte, NC. They couldn't hear it either. I recorded the sound and played it back to them.

The contact owns a 2018 Acura TLX. The contact received notification of NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling). The contact stated that while driving on several occasions at various speeds and while the vehicle was idling, there was a valve tap coming from the engine compartment, and the vehicle failed to restart. The vehicle was towed to a dealer, where it was diagnosed, and determined that a rod had pushed through the wall of the engine, and the engine needed to be replaced. The vehicle was repaired, but the failure reoccurred three years later. The manufacturer was notified of the failure. The failure mileage was unknown.

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.

While I was driving in the fwy I tried changed lanes and needed to speed so that incoming car wouldn’t hit me but my car was stalling. It has happened 3 times!!! I took it to the dealership and they said it’s the camera and that they don’t have the part on stock. I asked for a rental car meanwhile we wait for the part and they said they can’t do that. I stated to them that the car is dangerous not only for me but for the public if I keep driving it like that. They said there’s nothing they can do!

I am from Philadelphia PA and I was driving my car on a highway in rural WV and the engine stalled while driving. I was lucky enough that no other cars were around and I was able to veer the car off the road into a parking lot. The car would not re-start. I had to tow my vehicle to a local mechanic shop who could not help. I was stranded out of state on a holiday weekend with no acura in a 2 hour radius. I ended up renting a u-haul and towing the car 8 hours from WV back to a local Acura in Philadelphia. Acura replaced the engine due to the known re-call but refused to cover the cost of the tow or U-haul.

The contact owns a 2018 Acura TLX. The contact stated the vehicle was included in NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling), for a possible failure with the connecting rod, and the vehicle was repaired. Approximately 2-3 years after the recall repair, while driving 65 MPH, the vehicle started losing motive power while accelerating. The contact coasted to the side of the road and became aware of oil leaking from the vehicle. There were several unknown warning lights illuminated. The vehicle was towed to the dealer, who diagnosed the vehicle with 4 blown pistons, causing the engine to fail. The contact stated that the previous recall stated that the engine would be replaced as needed. The dealer informed the contact that the engine was no longer covered because the vehicle exceeded the mileage and time limitations. The vehicle was not repaired. The manufacturer was informed of the failure and opened a case. The failure mileage was approximately 110,000.

I was driving home from work and I started hearing a knocking noise and I was trying to get off the highway on the next exit but I didn’t make it the engine locked up and jolted. The car went into neutral luckily I was able to coast to the side of the highway.After getting it towed to the dealership they said it was a rod bearing failure and they needed to change the engine block. I had to fight for it to be covered under warranty but finally they covered it and they changed out the engine block.

Hi, I’m having issues with my fuel pump / engine and I seen online there was a previous recall for this issues regarding my year make and model but when I search my vin it’s not included? Not sure why when I’m having issues related to that exact recall. I believe it can be related. I took it to Acura and they want to charge me 5,000 dollars for repair. I have a 2018 Acura tlx 3.5 v6 which is stated in this photo attached. Can I get some more clarification please? I’m having all issues notated on the photo. Regarding car idle, fuel issues, stalling and more. My car slid into Neutral while I was driving twice! Super scary. When I took it to Acura they diagnosed everything that was in the recall? Not sure why my vehicle isn’t included when it’s very obviously related

My engine makes sounds and possibly there's some shifting noise when I'm not changing gears while driving on the highway. the dealer routinely checks my fluids,so the transmission fluid is fine. I even had a transmission flush after reading an article about this engine. The engine ticks like the rows are sticking. These are all characteristics of the published letter last year recalling Hondas and my car year make and model. Please furnish me with a recall letter so I can have this engine fixed before it dies or burns out on the highway causing injury or death

Vehicle starting making ticking noise, I called Dave White Acura. It very quickly turned into a very loud knocking noise. I called back and they told me to have it towed in which I did. I also took a video of the car knocking. Dave white Acura called me first thing the next day and said, we started your car and it is knocking so loud we immediately shut it off. But no updates were made to my service papers other than my initial phone call. I was advised by Dave White Acura I needed a new engine. I of course asked why, their response was, it’ll be cheaper for you to just put in a new (rebuilt) engine in than for us to tear it apart to find out exactly what it is but you definitely need a new engine. Again, Dave White failed to provide the necessary updates through the process and now Honda is refusing my reimbursement. I paid over $8016 to have a rebuilt engine but into my 2018 TLX.

My name is [XXX] On [XXX] while driving to lunch from work. I heard a faint knocking noise from my car. Came back to work and schedule an appointment with my mechanic dealer in Atlanta and there i notice a recall regarding the rod bearing. On the way back to where I was staying in Savannah Ga, the noise gotten a little louder when i pulled up in the driveway. I didn’t want to drive it so i call a local Acura dealership in Savannah. The tow truck that came to pick up the car ask if the car was drive-able to load on truck. When i crank it…he said that the rod. From the car was towed to Southern Motors Acura in Savannah. My dealership mechanic is Nalley Acura in Atlanta Ga. Since Nov 30th, i been in a rental out of pocket since Feb 25, 2024. Each time i speak with American Honda they tell me the parts are not available as of yet. This has been an expensive and frustrating process dealing with them and nothing seems to be heading in the positive direction. At this point i want a new engine. Reason being, the car has been sitting idle for months and the existing parts that’s not being in operation may no longer be of good use with any new parts. I work in Manufacturing as a manufacturing engineer. This happens in Aerospace all the time. Trying to install new part along with existing parts that haven’t been in use, may have corrosion, will eventually go bad due to shelf life and seasonal weather changes. Please assist me in this matter. My number is [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Acura has a safety recall on my vehicle for the rod bearing causing engine to seize and my engine seized I purchased the car in 2022. I was not aware that the engine was replaced in the vehicle before. The engine serial number does not match the vin but Acura is saying they won't replace it because the engine serial number doesn't match the and want me to pay 8k-10k to have it replaced. Being as though this is a known problem with this engine for years it's possible the previous owner could've replaced the engine for the very exact same reason there's a national recall for it now.

My car broke down on me in August of 2023 with a rod that connects to the engine being the issue. Now here we are 7 months later and I still am paying for a car that does not run. They won't inspect it to figure out if it's covered under the recall because there is no remedy for the recall. At this point, I have had to buy other cars while still paying on this one with no timeline of when to expect a fix.
