We both bought a pre-owned 2020 Acura MDX around the same time and we were sure it was a reliable car. Now that there have been recalls for 2 issues 8oz the 2016 - 2020 models, is there need for concern. Thanks
Here is the NHTSA report for recall 23V751000:
https://static.nhtsa.gov/odi/rcl/2023/RCLRPT-23V751-4249.PDF
The rate is pretty low...
Estimated percentage with defect : 1 %
The issue involves mis-shaped crankpins. Report says:
If the connecting rod bearing seizes, the engine can be damaged
I am not an engineer, but it seems to me that if the engine did not seize, then there shouldn't be damage.
The remedy for affected vehicles:
The remedy components have properly ground crank pins and are within applicable specifications.
I think that means you get a new crankshaft, thus resolving the issue.
I would probably keep the car.
Hope that helps.


@imperator thanks so much, I’ll do it! I appreciate you researching and explaining this.

Maybe. What's the recall for?
@imperator rod bearing replacement, fuel pump recall, auto idle stop restart, tail light not sealed properly. Thanks for the advice
only certain ones. Did you check your VIN to see if your vehicle is affected?
@imperator yes, I received recall notices for all 4 from Acura
so what is your question exactly? I mean you get the recalls fixed now. Worrying doesn't really help anything.
@imperator i’m wondering whether to get rid of it. When I scheduled the recall service, the dealer told me it could take a day if it was just the recall issues or longer if the engine needed to be replaced! Fortunately, they just did the recall issues and it’s running fine but I’m wondering whether to get rid of it in light of the seriousness of the problem that could’ve damaged the engine over the previous five years.
how many miles?
@imperator 33,965, thanks again
Is Acura extending powertrain warranty for these cars?
@imperator not trust I have been told but I will look into it. I’m assuming the main concern is the rod bearing replacement?
That would be my main concern because engines are expensive. The other things seem trivial in comparison. I haven't researched the issue too deeply, so I don't know how bad they are, but a cursory read suggests the problem isn't very widespread. As for the other things, almost no vehicle is perfect from the factory. I'd say you still stand a good chance of coming out of this with a good vehicle.
@imperator “Acura is not explicitly extending its powertrain warranty solely due to the connecting rod bearing recall. The recall itself provides the remedy for the defective rod bearings and potential engine issues. While Acura isn't extending the original powertrain warranty due to the recall, the necessary repairs or replacement are covered, and any new engine installed will have its own warranty.”
Now that there have been recalls for 2 issues 8oz the 2016 - 2020 models, is there need for concern.
That depends on the recall. Cars could possibly be recalled due to something as stupid as faulty TPMS sensors, or, in the case of my 2017 Mustang, backup cameras. I haven't taken it in for recall work, because I use my mirrors, not the backup camera. Now, Ford has recalled their 10-speed automatic transmissions at least three times now, because of poor quality design. Backup cameras are just a nuisance and don't affect drivability. With a transmission, that's another story. I wouldn't touch any GM-Ford 10-speed automatic transmission with a 10-foot pole because of all of their recalls.
