It takes two months to get an appointment and service is poor
I made an appointment to fix the lag when applying the gas pedal. It was very noticeable each time I drove it. Two months later I got to drive one of the mechanics around who said he did notice it too. He wanted to drive it home so he could get a true idea of what’s going on. That would have been a 160 mile round trip! Why, if he already acknowledged the problem? He wrote that he found no problem.
I took my car to a certified garage for an oil change, etc rather than wait two months for Hyundai. They said I had a small oil leak, two months later Hyundai said there was no leak, but there was a recall for something having to do with the fuel system. I thought they finally will address the problem. They would call when they got the parts to schedule an appointment.
Meanwhile I replaced the air filter with one that was high performance which did help decrease the lagging.
You guessed it, two months later, I took it in and found there was no part to change but the software was updated! I asked if this update was going to eliminate the lagging and was told no, they needed to add a sticker. I’m not sure what that meant but I’m very dissatisfied with the level of customer service.
