If someone takes there vehicle in for a check engine light then you should get it back fixed right . Nope . not here . I paid them for a so A solenoid replaced and still got the engine light back on next morning.

They did the same to me. Supposedly replace Solenoid, Engine light came back on 10 miles down the road. I new they had not taken it for a test drive because the miles going in were the same as the miles going out. Know I am in a battle with them because they charged me for the service which should have been covered under warranty.

More likely they are bad at being good technicians. My truck was in 5 times with no repair

Could be multiple things wrong with vehicle I've had that problem check engine light gives a code for things that are not working correctly
