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.

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.

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

I am concerned because the 2018 TLX Acura I purchased is having stalling and starting issues . When I first purchased the car and it had fewer than 17,000 miles problems appeared with the lights coming on, parking break and emission issues. It had to be repaired 3 times. The recalled Fuel system/fuel pump (recall # 19v060000) was replaced in Feb. 2020, which I hoped fixed any mysterious stalling. The first time it stalled I was in a COVID parade at work to support the community. It started up and I did not think about it again. That was in the spring of 2020. Again on Thurs., July 8,2021 the battery light came on and the car stalled while I went to push the gas peddle to go at a light that turned green (It occurred twice in one day). Instead the car stalled. I went to restart, first it said stuck in gear, then it was fine. The dealer claims it is because the gear selector switch had crumbs and too much dirt in it. I find it strange that Acura left such a vulnerable part exposed to elements with cup holders next to it and in a society that has a drive-thru for almost any food. Approximately one week before I got the same messages when pulling into a parking spot just before stopping. I restarted the car and it was fine. Also on May 24, 2021 my car, which had 71,657 miles had another issue with the Green key light flashing and the car did not start. The dealer replaced the control unit for keyless entry. It first appeared when my brother couldn't start my car. He told me and I went to start the car and it was fine. He was not familiar with my car and I thought maybe he didn't hold the brake to start it. Not long after I went to leave for work in the morning and the car did not start at all. I saw the blinking key. my car was towed to the dealer and repaired it. I have never had a car with this type of repeated problem of stalling and not starting. It may be different parts, but are they band aids for something bigger?

I BOUGHT THIS CAR ON OCTOBER 7, 2017 AND BY DECEMBER 22,2017 (DEALER REPORT ATTACHED), I HAD ALREADY EXPERIENCED AND REPORTED FOR THE FIRST TIME THE MALFUNCTIONING INFOTAINMENT SYSTEM ON MY 2018 ACURA TLX. THIS ISSUE IS ONGOING. THE TECHNOLOGICAL FLAW (PICTURES ATTACHED) IS THAT THE INFOTAINMENT SCREEN WILL FREEZE DURING OPERATION OF THE VEHICLE. THIS IMPACTS SEVERAL ESSENTIAL SAFETY AND DRIVING CAPABILITIES. WHEN THE SCREEN IS FROZEN, THE BACKUP CAMERA FAILS TO DISPLAY AS THE FROZEN SCREEN WILL NOT UNFREEZE UNTIL THE CAR IS TURNED OFF AND BACK ON. THIS MEANS THAT YOU HAVE TO PARK ON THE SIDE OF THE ROAD TO RESET THE SYSTEM. THIS FREEZE ALSO CAUSES YOUR PROGRAMMED GPS ROUTE (ON-SCREEN AND VOICE DIRECTIONS) TO GO HAYWIRE AND COMPLETELY FAIL, AGAIN REQUIRING YOU TO LEAVE THE ROAD AND FIND A PLACE TO PARK, TURN OFF THE CAR AND TURN IT BACK ON. ON SEVERAL OCCASIONS, I HAVE BEEN ON FAMILY ROAD TRIPS AND THE INFOTAINMENT HAS FROZEN AND I HAVE HAD TO LEAVE THE HIGHWAY AND RESET THE SYSTEM. THIS IS DANGEROUS FOR ME AND OTHERS GIVEN THE TERRAIN IS UNKNOWN AND DRIVING (ESPECIALLY AT NIGHT) CARRIES A LOT OF RISK. I HAVE ATTEMPTED TO ADDRESS THIS ISSUE NUMEROUS TIMES WITH FIVE DEALERS IN THE SAN FRANCISCO BAY AREA. NONE OF THEM HAVE TAKEN ACCOUNTABILITY NOR ACKNOWLEDGED MY PROBLEM, SAYING THEY CANNOT REPLICATE IT. HOWEVER, I HAVE NOTICED THE INFOTAINMENT FREEZINGS TEND TO OCCUR ON RELATIVELY LONGER DRIVES. THIS INFOTAINMENT DEFECT IS NOT UNIQUE, THERE ARE SEVERAL COMPLAINTS AND ONGOING LAWSUITS REGARDING THE INFOTAINMENT SYSTEMS IN ACURA TLX AND RDX OF VARIOUS YEARS (2019-2020), BUT MY MODEL'S YEAR HAS NOT BEEN ADDRESSED. MY FAMILY AND I DO NOT FEEL SAFE IN THIS CAR. I BOUGHT IT WHEN IT JUST CAME OUT AND IT HAS BEEN A DISAPPOINTMENT, COMPOUNDED BY THE LOW-QUALITY CUSTOMER SERVICE THAT HAS CONSISTENTLY IGNORED ME FOR THE PAST 2+ YEARS BECAUSE THEY CLAIM THEY CANNOT REPLICATE IT. *TR

Opened Aug 20, 2025 · No close date supplied
Status: open (inferred from source dates) · Engine
The Office of Defects Investigation (ODI) has received 414 reports of connecting rod bearing failures in the 3.5L V6 engine used in the following vehicles: Model Years (MY) 2018-2020 Acura TLX, MY2016-2020 Acura MDX, MY2016-2020 Honda Pilot, MY2018-2020 Honda Odyssey, and MY2017-2019 Honda Ridgeline. The subject engine failures were analyzed as part of a Recall Query (RQ24013). It was determined that these engine failures are outside the scope of Honda Recall 23V-751. Further, evidence gathered in conjunction with RQ24013 does not suggest this failure is caused by the same crankshaft manufacturing defect that is addressed by Honda in Recall 23V-751. Based on analysis of data from RQ24013, NHTSA has closed that investigation. The significant number of reports of engine failure in vehicles outside the scope of RQ24013 presents a potential safety risk that warrants further investigation. ODI is opening this Preliminary Evaluation (PE) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy.

RQ24013 · Engine Failure
Opened Nov 8, 2024 · Closed Aug 20, 2025
Status: closed (inferred from source dates) · Engine
On November 8, 2024, the Office of Defects Investigation (ODI) opened Recall Query RQ24013 to assess the scope of Honda recall 23V-751 after receiving complaints that alleged connecting rod bearing failures in vehicles that were not within the scope of recall 23V-751. In November 2023, Honda recalled 248,999 various Model Year (MY)2016–2020 Honda and Acura vehicles equipped with the 3.5L V6 engine. Honda recalled these vehicles due to a crankshaft manufacturing defect that caused premature connecting rod bearing wear and engine seizure. While the out-of-scope failures involved in these complaints appear to have a very similar failure mechanism as the recalled engines, a thorough analysis of all available data from Honda has not indicated that the same manufacturing defect exists in the out-of-scope engines as the engines recalled by 23V-751. Based on this analysis ODI has determined that Honda has properly defined the scope of recall 23V-751. Consequently, ODI will close this RQ investigation. NHTSA will continue to investigate these complaints of engine failure as part of a new Preliminary Evaluation Investigation (PE25008). The Agency reserves the right to take additional action if warranted by new circumstances.
