A connecting rod bearing is failing in my 2014 Acura MDX which could have led to complete engine failure while driving my family. Absolute Auto Center of Berlin, CT confirmed the issue and noted that Acura has recalled 2016-2020 MDX models due to connecting rod bearing defects but have not expanded the recall to include earlier model years that are also impacted. There were no warning lamps or messages prior to or during the issue, it was identified due to a loud knocking with the engine around 3-4,000 RPMs.

I change my own engine oil every 3,000 miles. During the past year with three oil changes completed, I have observed aluminum pieces in the bottom of the oil change black pan. Because my wife's 2017 Acura TLX was the subject of the crankshaft and connecting rod campaign (the dealer had to replace the crankshaft and all of the connecting rod and main bearings) I am familiar with the issue of non-concentric crankshaft connecting rod journals, and so have been surprised that my 2014 MDX with the same 3.5 L V6 has not yet been included. I am pretty sure it does suffer from the same defect as evidenced by the aluminum in the engine oil. If it fails at hihway speeds, that would possibly cause a safety incident.

I'M seeing several reports where ACURA has a major recall on their MDX models from 2016-2020 however i have a 2014 model but I have suffered the same engine failure due to a connecting rod issue that has caused what they call a spun bearing I have tried to contact American Honda to file a complaint but they just keep denying me since my vehicle is not part of the recall but by sheer coincidence my engine has failed I had no warning signals that would of indicated this problem and I have had the car fully maintained by ACURA Dealerships since I bought the car in 2017 I see where several hundred other complaints have been filed due to ACURA's faulty issues - ACURA needs to expand their recall list to go back as far as possible since they seem to be having the same issues with previous models not included in the recall

There is a known issue of Certain Acura MDX models having a "judder" (i.e. bouncing rev counter) at certain speeds. This causes the torque converter to not lockup and continue to find the right gear, per se. This is a known issue and Acura has a TSB (16-062) for this: https://www.tsbsearch.com/Acura/16-062 The issue is, even though, unaddressed in a timely manner and continual use of the vehicle may deteriorate the transmission, Acura doesn't fix this free of charge for vehicles not under warranty. Dealer quotes $800+ for a total 1.6 hours of work (based on the TSB bulletin). This is outrageous and monopolistic behavior in a free market. Moreover, typical mechanics doesn't have access to the special computers needed to perform the software update, required by this TSB. I am reaching out to request Acura (Car manufacturer) to cover this under recall and not charge the customer this ridiculous ~$400/hr labor rate just because I can't update the software from a local mechanic.
