My Kia Optima engine seized up completely at 71,000 miles. Engine totally failed. I was prepared to purchase an engine from CARMASTERS, however they encouraged me to contact Kia to see if this repair was under recall. Sure enough, Kia authorized complete replacement of the engine long block assembly saving me thousands of dollars. CARMASTERS was influential in this turnaround of events and they have my sincere appreciation. They also have my trust when it comes to future repair/maintenance requirements when they occur. Many thanks to CARMASTERS for looking after my best interests. They are a Tier One repair facility!
