Wow, it's good to know I'm not alone in this Santa Fe engine nightmare! I'm in the middle of it with an extra legal battle. I have a long story, mine starts out like everyone else here, but the end might make you feel better about yours....
I have a 2017 Santa Fe Sport and I live in San Diego. I'm the second owner having acquired it at 17000 miles in 2019. I got a good deal for it and I paid for the extended warranty when I got it. Since then I have absolutely loved this car!
At around 75000 I first saw my oil light come on. I'd been meticulous about getting my dealer maintenance done and I hadn't heard of any issues with this car, mostly because I hadn't had a reason to research. After all, per reviews it was the #1 midsize SUV and for reliability in America when I bought it.
I took it in on my next maintenance and told them I had to add 3 or 4 quarts since the last oil change which was odd. They looked and said I had a crack in my oil pan and they would forward the report to the warranty dept. I told them I haven't seen any drips under my card so I don't think I'd lose "quarts" through a crack. I mentioned that I was leaving the country for a couple weeks for work and to just leave me a message of when to come in to get this taken care of.
I come back to no messages. I call them 5 times leaving a message for someone to contact me and of course no return calls. The dealership I take mine to is in another part of town that I normally don't have a reason to go to.
Last October I finally go in to make someone talk to me. They then tell me the warranty submission was only good for 14 days and I need to bring it back in to be looked at again. I ask when is my warranty up and they tell me 92k. I look an at that point I'm at 93k. Now I figure I have to eat an oil pan replacement and I dealt with my oil change on my own then since I'm adding a quart every 2 tanks of gas.
Fast forward to 16 Feb, I'm driving to Lake Havasu and suddenly my check engine light comes on and the engine starts missing horribly in the middle of the desert past Barstow. I luckily made it to the next rest stop and looked around under the hood and car and found nothing visually wrong. I had oil then and when I left the house. No smoke. No leaks. It started right up and ran like crap but we were able to make it into Havasu which was the only decent sized town near by anyhow. In my shade tree mechanic mind, I have a bad cylinder, spark plug or coil.
There are no Hyundai dealerships within an hour of Havasu. So I spend the entire Sat morning trying to find a mobile mechanic to come by and look at it. There's plenty of them in town but either they were busy or they wouldn't answer their phone. One finally said he'd get back to me and take a look. Hours go by, I call him. He says he'll call me right back and that's the last I hear from him. He sends my calls to voice mail.
Here's the crazy part of this story- I find one little auto repair shop that said they would meet me Sunday morning (19 Feb) and at least get a read on the engine code. They were super nice, had been local for a while and had 4 and 5 star reviews online and the only ones that would take me in anyhow. The code they read was what I suspected but it was Sunday morning so the mechanic wouldn't be able to look at it until Monday morning. I had to be in Palm Springs that night so I left it with them and got a rental. This is when I start online researching to find the Hyundai engines lose oil and then fail. Great...
20 Feb they tell me my engine is shot. Compression test shows #3 cylinder is at 0 pounds and #4 is at 100 pounds. The other two read at 190 (normal). So they say they will replace the engine for $4700 and that it would take a week to install after they get it in. I'm thinking that's really not a horrible price for that job. They need $2200 to order the used engine, so I give them my credit card number and I make my way home in the rental.
I call weekly and talk to the mechanic. Friendly, talkative guy. 3 weeks in, he says the engine finally came in and they were going through it to ensure the oil and water pumps were good and then install it. Another week goes by and 12 Mar I call to ensure things are moving along. This time one of the other mechanics answers and tells me that the owners skipped town with all the money and other than the diagnostic, nothing had been done to my car and there was no engine ever ordered. The only thing he can do as the only unpaid employee left is to ensure I get my car back.
After I collect myself I immediately call my bank and dispute the charges first. 15 March I then rent a U-Haul and drive 5 hours to Havasu to get my car, thank the remaining honest guy there and file a police report on the business. Luckily my car was not damaged and they didn't tear it apart. The police inform me that the owner/mechanic I had been talking to is a convicted felon and serial con man and the business is under his daughters name and they are both on the run. The US Marshalls and Havasu Police are looking for him.
I'm normally a very patient man, but I called Hyundai of North America and couldn't take their endless phone tree that only wants to direct me back to a local dealership. Yesterday and today, I have called my nearest Hyundai dealer twice. Both times no one in the service department answers, so their receptionist talks to me, takes my information and problem and says they'll give it to the service dept.
Todays receptionist tells me that she doesn't see yesterdays message in their system. So she tells me she's forwarding todays message to the service department and service manager, labeled as urgent. That was 2 hours ago and they are closed now...
I'm seriously considering selling my car as is to pay off the $5k I owe and start fresh with something else.
