After driving it for two days light came back on so I took it back and got charged again telling me it was an oxygen sensor and charging again for diagnostics. Oxygen sensor showed up before they erase the codes according to Colorado Air. Anyway I thought this would fall under the same first diagnosis but it didn't so I got charged again . Awesome people. Just thing that charging twice was disappointing.

The most unprofessional service. Got my water pump changed, got the car back with a p0410 code…read more They denied being near the part, although the part is right above the water pump. I called to see if they had changed the housing thermostat with the water pump because I've changed everything else and I'm still getting codes. Won't even answer my calls. Tells me if I want them to fix it that they're basically gonna keep my car for a prolonged period of time because they "don't know what happened". The only thing wrong with the car originally was the water pump. I've been lied to every single time I've spoken to them.

I have felt taken advantage of many times using other auto repair places, but never at Aptitude Auto. They make the effort to explain exactly what is wrong and have shown me the bad parts to back up their work. This week I brought my car in because the brakes were squeaking. Juan told me what he could do to resolve the noise, but made sure I knew that I was safe without the repairs as well. It is rare to encounter such an honest mechanic- people who would rather be honest than just make some easy money. Thank you, Aptitude Auto!! You've got lifelong customers because of your fantastic service.
