I had two case numbers with Hyundai related to my brakes and fuel efficiency; the first was Hyundai Consumer Affairs case#: 12894630 and the second was Hyundai Consumer Affairs case#: 15512885. Both cases were closed prior to me having any say in the decision (email/phone records show this). After my braking unit fails for the second time and I noticed a significant drop off in fuel performance (mpg), I asked for another Hyundai rep to test my fuel consumption. When the results proved to be better than I had ever seen my car perform, ever, I asked for the rest specks. This was escalated to Hyundai corporate, who responded 'unfortunately your case manager cannot provide any tsb's because it is proprietary information. As far as warranty extension, regrettably that is not an option. However, if you were to have brake concerns outside of warranty, Hyundai will review for goodwill if the problem is something that was previously repaired under warranty.' This answer failed to consider the mileage I was already losing in my hybrid which performed worse than a non-hybrid model whenever the brakes were failing. I made good faith efforts to report my problems in the hope Hyundai would resolve them.
