On several occasions I have experienced issues with the performance of my vehicle. Upon start up and attempting to move forward while the car is in drive the vehicle hesitates to move and feels like it is going to choke and stop. I have experienced this same issue at stops while the car is in operation. There is an open recall for 2015-20 TLX no SH-AWD Fuel Pump Mtr Saf Recall Exp2, RECALL DATE:12/18/2023 which has yet to be fixed. I have been told by Tempe Acura that the parts are not available and basically I will be called when the parts are available. My safety and the safety of others are at risk when the car is not accelerating and causing a stalling or non-movement of the car. I have experienced the car stalling abruptly and coming to hard stops. The problem has been confirmed by the dealer by notice in the mail. The vehicle has been inspected when another recall was fixed which took over a year to resolve. This specific issue has yet to be resolved. There was another issue of the car stalling, which the dealer states that the electronic system needed a computer update. The problem first appeared when I purchased the car from {XXX].

I received two recalls and multiple notices saying the parts are not available for the recall. Over 6 months later I receive a notice the parts are finally available. I tried to make an appointment with my local dealer and was told they will not repair unless the check engine light is on. If what happens in the recall (fire, crash or injury), how will I be able to get the check engine light to come on? I'm afraid to drive the car because I don't want to be stranded, plus I don't want the car to catch fire, cause a crash or be injured. Why isn't Honda/Acura making the parts to correct this problem and why is the dealer not complying with the recall notices I'm receiving? On the Acura recall website, when I enter my VPN, it notes to please take immediate action to have your vehicle repaired but the dealer won't do it! As I'm looking at the additional details below...it appears that a fire, crash or injury needs to happen. Unbelievable!

We have almost been rear ended multiple times, the transmission stalls and will not “go” when you press the gas or the car won’t even turn back on. We have contacted Acura and a local dealer. Both say they do not have a remedy for this issue yet even though it’s part of the recall and keep pushing it off to the next season. Each time I call for an inspection, I get told there is nothing they can do. I ask about seeking legal advice and they just tell me they don’t have a remedy so a lawyer can not help me.

PE25008 · Engine Failure

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.

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. 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. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign.

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.
