I am filing a safety and compliance complaint regarding execution of Federal Recall Campaign #26V365 by Valley Stream Acura and sales fraud by Paragon Acura. I purchased this 2016 Acura MDX from Paragon Acura on May 29, 2026. I have driven it only 550 miles, placing it strictly within the statutory New York State 60-Day Used Car Lemon Law Warranty window. A certified 6-page independent ASE forensic report documents that Valley Stream Acura bolted the federal recall brackets directly onto severely cracked rear control arms and rusted struts without disclosure. Furthermore, Paragon Acura forced a brand-new front control arm link onto a deeply pitted, scaling, and structurally compromised front steering knuckle to mask pre-sale defects, signing a false NYS highway safety certification. The vehicle was released to me with a bone-dry, empty engine cooling loop, creating an immediate fire hazard. Acura Corporate (Case #16437213) refuses to issue a corrective directive, willfully leaving a non-compliant vehicle on public roads.

I started the vehicle and steering wheel was frozen and EPS, Brake, and lane departure lights on the dash. I shut the car off and let it sit for five minutes. Restarted and the steering wheel came back to normal. but all light remained on. I drove the car about half a mile and the lights went off. When I got home, I shut the car off and started it again. The wheel was frozen again, and all the lights came back on. I shut the car off and re-started and steering came back on. I'm afraid this will happen again but while I'm driving. I looked up the issue but no recall but a lot of complaints with same problem. I cannot drive like this for it can be dangerous if I'm driving and lose control of the vehicle and hurt someone or myself. I took the car to a mechanic, but he said there is no current issues just stored codes. Today I had the same problem.

The vehicle frequently experiences problems while idling at red lights or stop signs. Specifically, the engine suddenly shuts off after displaying a message that "Idle Mode is unavailable." This has occurred multiple times, and on five separate occasions, the vehicle became completely immobile, requiring towing to the nearest mechanic. Initially, I had the flywheel and starter motor replaced, which cost me approximately $5,000. However, just three months later, the same issue reappeared. Most recently, while driving home from work, the idle mode failed again at a stop sign, and the engine stopped running. I contacted Acura/Honda regarding this issue, but they informed me that it is not their responsibility. At this point, I am unsure how to proceed or where to seek a reliable fix, and I am concerned about the safety implications of this recurring failure.

I am [XXX] and I have owned Honda/Acura since I was 16 yrs old. My last vehicle was a Honda Odyssey minivan with 423K when I donated it, running well to a family that fostered kids! I bought a new 2016 Acura MDX and now it is 8 years old and has 180K on it. I get the oil changed and other normal service maintenance done only at Honda or Acura dealerships. I have never had a car accident and I take care of the maintenance early. All of a sudden, on Friday, [XXX], I had just started driving ( ~20 minutes in the car) and every light started flashing and the car sounded funny and it was hard to drive. I immediately got off the highway and found a repair place (Red's auto repair) right off the exit. They had me shut off the car. Then they checked the oil, which was showing 70%, and I had just had it changed less than 1000 miles earlier, and it had plenty of oil. They told me I could not drive the car! They said "something is wrong with the engine". Currently, LaFontaine Acura has my car. I have a loaner from them. They said it "spun a bearing" in the engine. Apparently there is a recall for this same problem for my year, make and model, but "currently" my VIN number is not included? And, it is the exact same problem bearing from the recall! THIS IS CRAZY! My car has been well taken care of and I would expect it to get at least 350k miles at least before any issues. If the same problem was recalled for other cars, why not mine? It is un-drivable now. I think that Honda has changed their manufacturing because in 43 years of driving Hondas they always are reliable and work well for years and years. My 5 adult kids drive Hondas as well! Never a problem. I think I got a vehicle with a defect that should not be, especially when the car has always been maintained so well, with the service records to show that. PLEASE HELP GET THIS INCLUDED IN THE RECALL FOR SAFETY! What is my next step to ensure that my car is included? Thank you very much INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

We have taken our 2016 Acura MDX to our local dealer three times in the past to complain about noises (clicking and thumping) coming from the front end of the vehicle. Each time the vehicle was under warranty and the response we got from the dealer was "no problem found". Two weeks ago (02Sept2023) we took the Acura MDX to the same local dealer and are told both of the front control arms need to be replaced. Since we are no longer under warranty it would cost us $1559.78 to replace both. And we are also informed that control arms on this vehicle do wear out frequently and they keep a supply on hand to replace the for the many customers that have had the same problem. While we have not had a direct safety problem with this car yet, the car is relatively young and does not have high mileage or rough use. Based on the fact that this Acura dealer has experienced many problems with this vehicles control arms I would like to register the problem with NHTSA to investigate further.

AT 1300 MILES. VEHICLE EXHIBITED A CONDITION WHERE THE ENTIRE ELECTRICAL SYSTEM FAILED, TRIGGERING ALERTS FOR EVERY SYSTEM. EMISSIONS, STABILITY, EVERY SAFETY FUNCTION, BRAKES, STEERING. VEHICLE WENT INTO SOME KIND OF FAILSAFE MODE WHERE THE TRANSMISSION DID NOT SHIFT WELL AT ALL, AND THE CAR WAS BARELY DRIVABLE. VEHICLE DID THIS TWICE OVER A WEEKEND. TOOK IT TO ACURA, AND AFTER AN ANALYSIS THEY BLAMED "BAD GAS." THIS IS AN EXCUSE AS THE VEHICLE ONLY HAD 1300 MILES ON IT AND HAD ONLY HAD 2 FILL UPS, AND BOTH WERE WITH TOP TIER PREMIUM GASOLINE. IN ADDITION, I DO NOT BELIEVE SOME "BAD" GAS SHOULD CAUSE THE ENTIRE VEHICLE TO GO COMPLETELY HAYWIRE SHUTTING EVERY SYSTEM OFF. THIS SEEMS TO BE A MAJOR FLAW IF SO. HOWEVER, AS I DON'T BELIEVE THE ANALYSIS THAT IT WAS "BAD GAS", I THINK ACURA HANDLED THE SITUATION WRONG AND IS SIMPLY USING AN EXCUSE RATHER THEN DETERMINING WHY SOME SORT OF ELECTRICAL CONDITION CAUSED THIS MASSIVE FAILURE OF THE VEHICLE.

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.

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.
