Bad electric motor?

Bad electric motor?
Howdy folks. I’m new here and have been driving a 2007 FEH for about a a year. My wife and I really like it until lately. I think it has a drivetrain issue or maybe motor going bad? there is an intermittent grinding sound that last for a second and goes away and returns randomly. Still drives normally other than EV mode won’t function. Does anyone have any ideas on what might be going on with this vehicle? Thanks 😊

Intermittent grinding sounds are very difficult to diagnose. Can you localize it better? If the car will not go into EV mode, there are a number of reasons why that can happen. What you need to do is pull the codes, or have someone pull them for you (like Pep Boys or AutoZone if they offer that in your area) and let us know what they are so we can assist.

Have you ever changed the fluid in the transaxle? Also, how many miles are on the car and do you live in a hotter than normal or colder than normal climate (i.e., Death Valley, NV or Nome, AK)?

One more thought: If your air conditioning compressor is running all the time, the car will never go into EV mode because it is driven by the engine.. The grinding sound you are hearing may be the A/C compressor clutch, or the compressor itself.

I will attempt to access codes and report back. It’s a AWD with 143000 miles. I live in northern Indiana so not terribly hot. At first it sounded and felt like running over a small object. Now more like grinding after it gets warned up. The car came with good record of service so wasn’t thinking about trans fluid. I’ll look into that as well. The last time I drove it, it had had a new scent of something hot.
