Bought a used 2013 Impala at 30,000 miles and a year later i had to get my alternator and battery replaced. Also within that time my Satellite radio just completely stopped working, my traction control kicks in whenever i turn the steering wheel to the far right or left. I just went un to get my oil changed and was told that the cold cranking amps are significantly lower than they are supposed to be. So, now i the alternator/battery issue has come back and the dont want to fix the issue without me having to pay for something. I actually feel they sold me a Lemon cause there is just no way i have these kinds,of issues with a car and its currently at 69000 miles. I hate this place and will never get another car from there again. Ill never buy another GM product again either!!!
