Let me start by stating this is my 1st GM product and am greatly regretting that decision while I do love comfort an power of my cruze the customer service is pitiful. For the past few months I have been getting a check engine light about every 2 1/2 weeks on my 14 for NOX sensor 2 light ive been to a few different dealerships and they all have done the same thing start with cleaning plug and next time changing the sensor and then the next time changing all of the sensors in the exhaust with no resolve ive contacted GM twice about the issue and they just keep moving me to different dealerships and saying that dealers are their own entity and cant really do much else I thought I bought a GM vehicle with a GM warranty and all their hype about quality to be backed and supported by GM to resolve any issue I had to ensure I buy another GM product but apparently I was wrong and GM is done with you the second you drive it off the lot coming from Ford where every issue ive ever had is addressed timely and ensure my satisfaction as a customer this is just baffling to me that they refuse to stand behind their product and refuse to have an engineer involved even thou it is still under warranty and are just trying to run me out of it so it Is no longer their problem. So my question is has anyone else been having similar issues?
