Suspension

“In 2017 had my front control arms replaced after the driver side CV arm came off of the axle due to a recall. 5 years later (about 30k miles) the same exact situation happened now with the passenger side making a left turn. Thankfully both times I didn’t cause an accident but came close due to the wheel coming off of the axle. Brought to dealership, they had to get approval from corporate for the repair. Got a call 6 days later saying corporate denied the goodwill repair due to being “normal wear and tear” and they told me to call corporate. Just called corporate and they say that the dealership makes that decision. I shouldn’t have to pay for something that was recalled, repaired, and happened again 100% in the same fashion. Normal wear and tear on a CV arm is not 20-30k miles.”
