Is this common on a 50k mile expedition? Went in for a routine oil change and now they’re saying my belt is cracking... should I believe them? Lol

Funny, I just got mine back from service not that long ago and part of the assessments were:
Not sure if that's upsell or true wearing. I guess I'll have to take a gander at the belt myself.
- back of belt is starting to wear/ glaze
- minor play in both front inner tie rods
I currently have about 114,000 kms on it
The serpentine belt is made from EPDM, unlike the older neoprene belts it is not likely to crack in the vehicles lifetime. It will wear and may eventually fray. The tech telling you it is cracked is the first indication that you need to find a better shop.

While in for an oil change and tire rotation, I had a Ford service advisor tell me that my 2015 Expedition’s engine air filter was due for replacement.
I had replaced the filter with a new Motorcraft one the week before.
Nothing wrong with that belt. You can tell by the fussiness of the material on the rib side that it is a EPDM belt. Eventually thousands of miles from now the side of the ribs will start to polish and wear. At that point it will be time to replace it and relegate it as your spare. They even have wear gauges to indicate the amount of wear.don’t see any cracks or fraying.. maybe small white line, which is probably nothing. Felt it, and it’s all smooth.
