I own a 2018 Acura TLX with approximately 41,384 miles. While driving, multiple safety-system warnings suddenly appeared simultaneously, including: Lane Keeping Assist Problem Adaptive Cruise Control Problem Auto High-Beam Problem Collision Mitigation System Problem Road Departure Mitigation System Problem Brake System warning I safely stopped the vehicle, shut it off, and restarted it. The warnings initially disappeared but later returned, including when I started the vehicle to take it to the Acura dealership. An authorized Acura dealership inspected the vehicle and retrieved multiple diagnostic trouble codes, including U3000-49, indicating an internal electronic failure associated with the multipurpose camera/driver-assistance system. The dealership cleared the codes, retested the vehicle, and confirmed that the fault returned. The technician also tested the battery, alternator, starter, and camera ground. The brake system was inspected, and no separate braking problem was identified. The dealership diagnosed a failed monocular camera requiring replacement. Safety concern: Multiple driver-assistance systems became unavailable unexpectedly while I was driving, including collision mitigation, lane-keeping assistance, road-departure mitigation, and adaptive cruise control. The simultaneous failure of these systems creates a safety concern because the vehicle's collision-prevention and driver-assistance features may be unavailable without advance warning.

I’ve bought my 2018 Acura TLX used from Holiday Mazda in [XXX] in XXX Now that my nightmare with the Auto Engine Idle is over(the shop that replaced my starter in November 2025 some how got it so it doesn’t work anymore. But that’s not my issue. I’ve had this issues 5-8 times in the last 2 years. I will be driving and my top screen in in the dash(it usually displays navigation, CarPlay, etc) will turn off and flash a couple times. Then it take out my “radio” screen. It’s like it’s resetting because the screens remind me when it electronics reset snd start up. It goes for a total of 2-3 times. Thank the Good Lord my car keeps driving safely. Here is the second issue. I’ve had my parking, forward collision, and the one where it says” object approaching.” Off for 2 years now. When they are on they will start beeping and freaking out. I’ve cleaned in front of wheee those cameras are located. I’ve researched online. And can’t figure it out. Now that I have my newly licensed son ([XXX] old) driving the car I want to get every safety issue working. Acura can’t figure it out and so I don’t know Where else to turn. A fiend recommended I do This. I do have video of these things happening. I can included them if asked to. Thank you. Ps. I wasn’t able to upload video, I can email them if you send me an email address I’ll get it to you asap. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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?!

Engine
Filed May 27, 2026CA

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%.

I was rolling up to a stop light at approximately 20 mph when the frontal crash mitigation feature suddenly slammed the brakes on fully to a complete stop. I searched the web and found that there are other owners of this model that have had similar occurrences. I could easily have been rear-ended if someone had been following. I was lucky that didn’t happen. Since that day, I have been afraid to drive the car until I have disabled the feature.So every time I start my car I have to disable this mode. There is no known fix. No technical service bulletins etc. regarding this problem. Honda Acura needs to find a solution to this. I should not have to disable a safety feature that is actually making my car unsafe!

Engine

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 misinf

Suspension
Filed Jan 12, 2026TN

While performing routine maintenance on my 2018 Acura TLX, I discovered a critical structural failure in the front right (passenger side) lower control arm. The factory weld connecting the stamped steel control arm to the compliance bushing housing has failed and separated. Visual inspection reveals a clear manufacturing defect: there is a significant crater and void in the weld bead, indicative of incomplete fusion or a "start/stop" error during the manufacturing process. This is a latent structural defect, not a stress fracture from mileage or impact. The weld has begun to separate from the housing, leaving a visible gap. Safety Risk: This failure compromises the suspension geometry and structural integrity of the vehicle. If the weld completes its separation while driving, it would result in the control arm detaching from the subframe, leading to immediate loss of steering control, wheel collapse, and a high probability of a collision. Status: No warning lights were illuminated prior to discovery. The vehicle has not been involved in any collisions that would affect this component. The defective part is currently on the vehicle but is available for inspection by NHTSA or manufacturer representatives upon request.

Odometer Fraud. The contact purchased a 2018 Acura TLX. The contact stated that it was discovered that there was a mileage discrepancy. The vehicle was purchased on September 10th, 2025, as a dealer sale. At the time of purchase, the vehicle mileage was 76,410. At the time of registration, when the title was received, it was discovered that the mileage was 176,410. The title read, "Not Actual Mileage, Mileage Tampering," which indicated odometer fraud had been detected. After ordering the Carfax Report, the report indicated that the mileage 176,000 miles at the time of purchase. The contact had not reported the odometer fraud to any other parties.

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.

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 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.

While driving, my vehicle has randomly shut off mid-drive on multiple occasions without warning. This has happened both at low speeds and on city roads, creating a serious safety risk as the engine cuts out without any dashboard lights, alerts, or codes. I lose power steering and acceleration, which could easily cause an accident if it happens at higher speeds or in traffic. The issue is intermittent and unpredictable, making it difficult to reproduce. I have taken the vehicle to the dealership multiple times, but they have been unable to replicate the issue or find a cause through diagnostics. Honda has advised me to tow the vehicle the next time it happens, which is unreasonable given the uncertainty and safety risk of being stranded. At the time of each incident, there were no warning lights, error messages, or unusual noises. The vehicle has restarted after turning it off and on again, but the underlying cause remains unknown. I have opened a case with American Honda, but no resolution has been offered beyond repeating the same inspections that have already failed to diagnose the issue. To date, neither the manufacturer nor the dealership has confirmed the issue or replaced any parts. I am deeply concerned about the potential for this to happen in a more dangerous situation. I am reporting this to NHTSA in hopes that this issue is investigated and resolved before it leads to an accident or injury. Cause of issue: UNKNOWN. Vehicle available for inspection.

I was driving down the road out of town about 3 hours away from home when I heard a beep and car started to stop, later finding out it was going into “limp mode”. It was then towed to a car shop which was not any help, they stated that they didn’t know what was wrong with it and that I needed to take it to Honda down the road 2.5 miles that it just needed a system update; very mistreated and rude not offering towing service suggestions or anything told me I can still crank and drive it just not fast. I got into my car and drove it to Honda which would not go over 15mph trying to get there before closing on a Friday afternoon. After their diagnosis, I was told it was a fuel pump issue but my VIN was not included upfront but prompted me to file a claim report with Acura to see if I could get a reimbursement later on, which was denied due to no recall listed on my VIN which led me to file this claim to get my VIN reanalyzed as I believe it should be included since it is directly related to the known recalls on Acura and don’t agree that is enough to exclude or disprove my VIN. Unfortunately Honda did not have any courtesy vehicles to offer at the time so I had to have someone come pick me up 3 hours from home. The low pressure fuel pump was initially replaced but then stated there was still issue with my car and it was also the high pressure fuel pump as well, both of which are recalls listed on other various year and models of Acura.

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?

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.

Is the 2018 Acura TLX a good car?

It is not among the TLX years to avoid. Owners filed 97 complaints, against about 83 for a typical TLX year. The most common complaint is about the engine (37%). In NHTSA crash tests it scored 5 stars overall.

What is the most common problem with the 2018 Acura TLX?

The engine: 36 of the 97 complaints (37%) are about it. Owners most often say it knocks, grinds or clunks (42%), stalls (19%) and loses power (14%). The typical report comes at 89,000 miles.

How many recalls does the 2018 Acura TLX have?

4 safety recalls on file with NHTSA, the most recent filed May 21, 2026. 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 2018 Acura TLX problems start?

Half of the complaints that record an odometer reading came in before 47,700 miles. For the engine the midpoint is 89,000 miles.

Has NHTSA investigated the 2018 Acura TLX?

Yes, 3 times. The latest, PE25008 ("Engine failure"), was opened Aug 20, 2025 and is still open. 2 investigations are open.

Are there service bulletins for the 2018 Acura TLX?

The manufacturer filed 92 technical service bulletins and other notices for it with NHTSA, most of them about the engine (29), the fuel system (24) and the electrical system (14). 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

No unusual pattern of severe incidents in the complaint record.

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.
