Last year we started having an oil consumption issue with the car. Our mechanic told us we had to bring it to the dealer. The dealer told us we needed a new engine, or they could perform some sort of soaking Band-Aid. That lasted approximately 9 to 10 months. Now we’re back to needing a new engine again. The car is only a 2018 and should not need a new engine. The oil consumption issue seems to be a known problem with Hyundai yet they haven’t done anything about it.

Hyundai sold me a car with a faulty engine that requires a weekly oil change, and millions of others. I have visited Hyundai countless times in an attempt to have the dealership inspect the faulty engine that my vehicle has. Unfortunately, my concerns were ignored and brushed off and I was told to have other repairs instead. I continued to go to the dealership and complain and finally after an oil change, I returned to the dealership a week later because my car ran out of oil after just one week, and I was told by a service employee at that dealership that they can see how the engine is over consuming oil and advised me to let me engine BLOW up so that Hyundai can replace it, otherwise they were not going to because they don't want to spend the money. I was outraged!

I have gone to multiple mechanics who have confirmed that I have a faulty engine and that there is a recall on it. I have called multiple times in an attempt to speak with a manager, recently I was told there were no other options except for me to pay for or fix an engine that I did not damage. I am now considering on hiring an attorney and filing the proper paperwork that is needed or getting a NHTSA inspector. I have spent THOUSANDS just on oil changes. I have to get an oil changed every 10 days because my car runs out of oil after a week! It makes it a lot more difficult and infuriating that Hyundai have ignored my claims and refused to help unless I spend more money. It is very disappointing that I am not being heard or helped unless I take legal action. The amount of money I have spent on this vehicle plus the oil changes is really a shame. They are selling cars to people under the impression that it is a good vehicle but that is a lie and millions of others would agree.

Keep wasting money for parts that do not fix the oil consumption problem.

I purchased my car a little over a year ago from a dealership and after about 7 months I started having to add a quart of oil in between oil changes. Now I have to add 1-2quarts of oil every week!!
