I bought a 2010 MDX, and it has only run over 70,000 kilometers. Recently, it suddenly lost power, and the anti-theft system went off in the middle of the night. I took it to the repair shop and replaced the battery. A few days later, it lost power again. The repair shop thought the alternator's output voltage was low and suggested replacing the alternator. I replaced it as required, and the check results showed no issues. However, a few days later, it lost power again. Can anyone help me out?

It seems fine when not driving on the highway, but as soon as I do, the light comes on and stays on. Can any experts advise on how to fix this issue?
