Hi! First time poster. We bought my mom a 2007 Veracruz back in January. Ever since about halfway through January, it has had the check engine light and the airbag light on. Being that my scan tool isn’t a fancy one, the only codes I got were an O2 sensor voltage code and an evap code.

However when it was taken to autozone by my mom, it was revealed to have 32 codes present… multiple O2 sensor codes, transmission codes, evap codes, voltage codes, the works. Upon doing a bit of research, I found that many of these things supposedly setting codes were all on the same grounds. So I cleaned them and cleared the codes. 3 days later, all of them came back. Car runs and drives perfectly fine with no issues. Is it safe to assume that there’s something failing and causing the PCM to go haywire or could it be a bad PCM? Any help is appreciated as the local Hyundai dealership won’t look at it because it’s “too old”. Thanks!!
