Wire fretting in Engine compartment- have you noticed any?

Interesting...

I went out and looked at mine (2018 PHEV Touring), and the wire that you identify with the fraying does not exist in mine !
Do you have a BEV? I have the orange high-voltage wire, and the other black wire that has the "Y" just before leading to the ground bolt, but the 3rd wire that is fraying for you (in the middle and Zip-tied to the "Y") just isn't there !

 

Be interesting to know both build dates/VINs--could be a manufacturing change early in 2018 when someone noticed some fraying...

I'll go look at my (~March 2018 built) touring PHEV when I go out next; probably midweek (my car is in a commercial garage, I'm in NYC)

 

Just to illustrate, here is what mine looks like:



My manufacture date is - 8/'18... The VIN ends in 017995

 

The plot thickens...I may have to make a field trip later tonight

 

My 2019 looks like yours.

 

@MrFixit , mine is identical to yours, no third wire. 2018 Touring, vin ends in 009561. Manufacture date 03/18. @Nemesis, it will be interesting to hear why these are different.

 

@Nemesis -
Have you had this car since new?
Could previous owner have added some accessory with this wire?

 

Hi Nemesis Just checked, mine is the same as Mr Fixit... no gray wire; just the black ones, no fraying.. Canadian Touring Red 2018...

 

2019 Canadian Base. No 3rd wire. Bizzare!

 

My 2019 (made in Dec 2018) looks the same as Mr Fixit's.

 

So it looks like a very early car--it does sound as if they made the change, probably because of the chafing, early in 2018...

 

Please take pictures at both ends--those with a different routing can then take similar pictures--maybe you can get the dealer to install a new harness on the new routing as a warranty fix.

 

Interesting. I wonder if Canadian cars have an engine block heater?

Anyway, I'd take it back to the dealer for a warranty fix.

 

Glad you found out what that third wire was and thanks for letting us know. I was going crazy tying to find it in mine (mfg 12/18).
BTW, that zip tie looks way too tight and appears to be digging into the inner wrap on that wire bundle. I’d definitely replace it with one just barely snugged in after adding some padding like electrical tape. No way to replace the loom without removing one end of that wire. That may be why it wore through the outer loom.
