2015 ACURA MDX Complaints

My 2015 AcuraMDX engine seized while driving creating an unsafe condition as it occurred on a busy roadway. I suspect a rod bearing failure. It has been reported to Honda. The same parts listed in the 2015 RDX recall are used in my MDX but the 2015 is not part of the recall. My engine had a knock and had taken it for inspection at an independent Honda specialist. I had learned that the recall covers the 2015 model year for the Acura TLX, the official recall documentation only includes the 2016–2020 model years for the Acura MDX. There were no check engine lights prior to the stall and seizure of the engine.

I saw previous warning when I pulled my credit report on Experian, but I am not seeing any recalls currently. My driver side taillight is malfunctioning. It appears there is a problem with the seal which is allowing water to get inside the assembly, causing it to short out. I realize this vehicle is a 2015 but thought I would mention in case this is still an issue under recall.

For the last 50k miles we've taken our Acura MDX to the dealership for regular oil changes. Almost every visit results in a bad battery. We've had the dealership replace a side mirror due to the electrical and several batteries as well. They've kept it for several days diagnosing issues but haven't to this day found out what's wrong with it. Now my back taillight stopped working, we bought another one and replaced it for it to work for a couple months and stop working again. Now we've taken it to another place for diagnosing, they have said the inter taillight assembly and wiring needs replaced. Seems like this has been the issue the entire 6 yrs we've been complaining. The dealership says they took care of the problem already, clearly this is a safety issue when driving at night especially. Having a taillight that works off and on is not my idea of safe or "fixed" according to the dealership.

Acura issued Warranty Extension TSB 19-029 on 2014-2016 MDX with white diamond pearl paint. The extension covers the roof and rear door. My roof began peeling in or around 2022 and the roof was repainted without issue. The rear door just showed signs of the defect in August 2024, and the issue is clearly the same manufacturer defect as identified in the document, however, Acura is unwilling to correct the defect due to the warranty period now being expired.
