With only 50,800 miles check engine light produced several codes. I took this vehicle to 3 different places for a diagnostic test. They said it was power steering / a/c coolant leaking. With the 2nd diagnoses they found a leak with the auxiliary cooler (transmission fluid). So I had a complete transmission flush work done, but it's still leaking. .
