Had flat tire. Car towed to Midland Ford. Would not allow just the one tire replacement, I had to purchase all 4 tires. No service tech spoke to me about any other issues or tires regarding my vehicle. Finished work, same nigh hit a deer. Car was in body shop 10 days. After picking it up, drove approximately 5 miles, heard thumping sound and car started shaking, turned around to head back, shaking got worse went to pull over, left front tire fell off, studs intact, no lug nuts seen. Towed back to shop. Shop states they had no tires off car during repairs, Midland Ford isn't accepting any responsibility. We know they had all the tires off.
