We have a 2016 Acura MDX and it has automatically shifted to Neutral 3 times (twice while driving on the freeway and 1x yesterday while driving on the street at normal speeds) in the last 2 months. On the MDX dashboard, it will display "Emissions System Problem" and then display "Stop Driving When Safe. Transmission Problem. See Manual." However, the car will automatically shift to Neutral within seconds. My children's lives (7 y/o and 5 y/o) were placed in danger as a result of this system failure. I have contacted the Acura Honda Recall Specialists and Client Relations Representatives. The car is being diagnosed at Cerritos Acura dealership at the present time. A case number has been filed since our VIN shows no recall, despite it having recalls for other 2016 Acura MDXs.

White paint is peeling on roof and exposing bare metal. Risk of rust, corrosion and structural degradation. Background: Acura/Honda knows of an issue with their White Pearl paint from 2016 and has issued a TSB to address the paint on certain VIN numbers. However, many owners are finding that even though they have a 2016 White Acura MDX, the VIN is not covered by the TSB. The TSB extends the warranty to 8 years for any peeling of the white paint. Acura/Honda states that only the VINs that are in range of the TSB are affected, however many owners are experiencing the peeling/chipping of the paint even thought their VIN is not in range. A popular online forum, [XXX] has multiple discussions on VINs not in range but still experiencing the peeling/chipping issue. I have attached links to just a few of the discussions I found.

After traveling about on a 4 hour drive, my daughter who was driving the vehicle slowed down to make a turn. That's when she heard a loud clanking noise coming from the engine. She immediately pulled over and turned off the engine/vehicle. I went to meet her, and replicated the same problem when I turned the ignition switch to to on. It sounded as if there was some large piece of metal loose inside the engine -- it did not have consistency and was highly variable with regards to the sound it was making. The "Check Engine" light was on. Fortunately this did not occurr going at high/freeway speeds, yet the safety was compromised when my daughter was fortunate enough to leverage the momentum to get to the side of the road. Additionally, she was not in a spot where there was a shoulder/it was under an overpass, so she had to be careful and turned on her emergency lights. We had the vehicle towed to the nearby Honda Dealer. I am attaching their report and findings. They recommended engine be replaced; which we agreed to have done. Additionally, we continue to have problems due to the mounting and shacking which we believe comes from the installment of the new engine. We are submitting that report as well. At present, my daughter is not driving the vehicle and is relying on rides or borrowing other people's vehicles.

[XXX] 7 pm. As I was on the highway, warning lights came on the dashboard, “failing transmission, emission failure, and side mirrors failure.” I soon lost a lot of power. I purchased this 2016 Acura MDX in 2019 at Acura of Concord as a Pre-owned Certified with 20k miles. At the time of the transmission failure I had put an additional 17k miles. Total cost for a new transmission was nearly $8000. This does not seem fair to have to replace a transmission with so little miles. It seems as though this vehicle is a lemon. Approximately 3 weeks later, as I coming up the driveway, I noticed a huge chip of paint missing in front of the sunroof area. Now this appears Exactly as the recall or extended warranty demonstrates for 2014-2016 MDX White Diamond Pearl NH-603P. Honda claims this “VIN Does not qualify” for this extended warranty. Even the service manager at Acura of Concord exclaimed, ”How they explain to me that this vehicle does not qualify when it is the same year model, same paint, and that the paint chipped off Exactly the same way as described in the extended warranty recall.” In other words, Honda is forcing me to reach out to you because this VIN is not on the list and they do not wish to acknowledge that they are at fault. I do not feel that it right that I paid $8000 for a new transmission, and now I will have to pay $5303.70 to repair the paint on the roof. Please help me in this matter.

The paint on the roof of my 2016 Acura MDX is peeling, as described in Acura Service Bulletin 19-029 in August 28, 2019. The paint code NH-603P matched the service bulletin but Acura is denying me of any warranty because of VIN. This is a known problem for 2014 - 2016 Honda and Acura White Diamond or Pearl White paint NH-603P many people have the same issues based from a quick search on Google but Honda and Acura are denying many people because they ARE NOT expanding the VIN and or only restricting and addressing certain locations. There are no dent or scratches on my roof, no sign of weather damage. They used the same paint and same problem as service bulletin so obviously the problem was not addressed to all 2014 - 2016 MDX. Manufacture should be held responsible and expand their service to other customers with the same paint code as well.

While driving our well-maintained 2016 Acura MDX on a 30-minute drive on [XXX] , I heard a pop, and then the engine lost power. I couldn't get the RPMs over 2500. A fluttering noise evolved into knocking and the vehicle became increasingly sluggish and heavy. The check engine light started blinking, but the vehicle's temperature gauge showed no changes. There wasn't any smoke or unusual smells. I felt terrified trying to get safely onto the side of the road with cars driving at full speed. I had the car dropped off at our local service station and the owner determined that the engine cylinder was loose and lost compression with a knock. He says that the engine light did not give a code. The owner determined that we need to replace the engine. A rebuilt engine will cost us $8,000. When I called Acura, the service person I spoke with seemed surprised that our 8-year-old car with only 77,000 miles needed a new engine. Since Acura has so many cars to deal with on the latest recall, he said it would be weeks before anyone can look at it. I researched and found that our VPN was NOT included in the recent recall of 2016-2020 model year MDX vehicles all with the same problems. How can that be????

The vehicle was purchased at Mullers Woodfield Acura, 1099 W. Higgins Rd., Hoffman Estates, IL 60169, Tel. 847-519-9550 on [XXX]. I came home with the vehicle when it was dark. In the morning, I inspected the car and noticed paint issues where the bumper meets the painted metal and some areas around the sunroof and side edges of the roof. The dealer would not exchange for different vehicles; they offered to paint the areas, which they did through their insurance. Sometime later, around 2019, I noticed a small patch of paint missing on the roof. I took the vehicle to the dealer, where I found a Service Bulletin regarding this issue. The service bulletin dated 08/29/2019 was for the same problem I was experiencing. My dealer advised me that my VIN does not match the service bulletin. They quoted me $2,400 to repaint the car after they filed with Acura Care, which denied accountability. I went back and forth between the dealer and Honda Care but was nowhere. Nobody is taking responsibility for this manufacturer defect. I contacted them again today and was denied. I could not file a complaint with the person I spoke with, who stated she was the manager. This vehicle had paint issues from the start, and I reported it to the dealer and Honda Care and gave the Service Bulletin the vehicle year, paint color, and the claim the dealer filed with Honda Care. Pictures were taken, and the claim was denied because my VIN number is not listed with the Service Bulletin that came out. I am filing a complaint for a manufacturer defect that occurred with my vehicle from day 1, and neither the Dealer nor Honda Care wants to take responsibility. I am asking for a review of how the manufacturer can get away with this without any responsibility, especially since a service bulletin was issued.

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. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

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.
