NHTSA Complaint #11607744 — 2017 CHEVROLET VOLT

I took my car to Platinum Chevrolet in Santa Rosa, Ca. They did a checkup and claimed that both of the spindle axle washers were cracked and should be replaced ASAP. They told me that it could be very dangerous if I continued to drive the car without repair. They told me that this flaw was quite common on Chevy Volts. I researched on the internet and this flaw is reported quite often and is said to be dangerous. There is no recall for this flaw. If this flaw is very dangerous, WHY is there no recall?
