I'm having major buyer's remorse on a new car purchase. Occassionally the car will buck forward when accellerating, especially going from one gear to the next. It's a bang sound with a lurching. Oher words that could be used to describe it are: misfire, cough, hesitation.
Any idea what could be the cause? We took it to the dealership and of course no computer code came up and it didn't happen on the drive with the mechanic. I have to believe this is under warranty, right? I just made my first payment! Given this, how should I proceed? I'm concerned that I'm damaging the vehicle by driving it and that it may be unsafe. |

New new?
Or used new? |

| You’ll get better advice if you provide make/mode/mileage. |

| New. Bought the last 2017 Hyundai Santa Fe on the lot a month ago. 35 miles on it. Occassional banging/hesitation started at about 2,000 miles last week or so. |

| When does the banging sound happen? Is it when you are accelerating, going up a hill, or otherwise requiring a sudden increase in power from the engine? |

| When requiring a sudden increase in power, sometimes at low speeds. Its like it cant decide when to switch gears and when it finally does, its sudden startling and low with a kick forward. |

| Sorry, low = loud |

Log onto carcomplaints.com and search your year, model and transmission hesitation. There is a long list of people with what sounds like the same problem that you are having with that car. Somewhere in there you might find a solution. If the dealer continues to blow you off contact Hyundai USA and get them engaged. They may also have a twitter or Facebook page where you can register a complaint. Big companies hate social media complaints so they usually respond quickly. Good luck! |

Check online to see if there are recalls on anything anywhere in this model car.
Then look to see if others have posted on auto forums (not DCUM, I mean places like "Hyundai owner forum" etc). Do these first two steps pronto, OP. Then check your warranty. Print it out and go to the dealership with it in hand. (Seeing paper in a customer's hand can make some businesses...nervous. Good.). Tell the dealership they need to give you a loaner car while they keep and drive your car enough to experience the problem. If they balk, immediately take it up to the next level, dealership manager or beyond. The car is so new that you should be very assertive about this. If you do find a recall issue or a problem that other owners have reported, mention it. Dealerships do not want to deal with you coming back with a new car like this. They'll try to say you put in the wrong gas, you're doing something wrong, etc. I've had it happen. You'll have to TELL them to give you a loaner and find the problem. |

| I had the same problem with an mpv several years ago. The first time or so, I actually checked my rear view mirror believing someone rear-ended me. I needed new cylinders at 30k, just under warranty, and a new transmission at 58k....thank goodness for the extended warranty |
