This vehicle burns oil at an alarming rate. I am getting oil changes every 3K miles, and when I take it in, the dipstick is dry. I receive no oil lights to tell me it is low. I just had to get spark plugs and the mechanic at the garage told me this was due to the oil consumption issue in these vehicles. I am at 71,000 miles.

I was driving down [XXX] from my house.My engine light started to flash.I tried to accelerate my car barely went 10 miles an hour.I got Home 2 minutes later.There was major knocking.I had the car towed to [XXX], Hyundai, the only code that is showing up on the diagnostics, is P1326 there is an open class action lawsuit for this exact code. For the rod bearing failure, Hyundai is denying the claim, saying there's a gap in maintenance history on a car. I didn't own yet when I bought the vehicle. It passed a 190 point inspection. There's no way there was anything wrong with this vehicle.I am under fifty thousand miles , and if I was on the highway , it could've been deadly i could not accelerate. No other lights were on in the vehicle, except for the flashing engine light.I have already reported to the better business bureau and they have sent it to arbitration. I have contacted the escalation department for Hyundai.They opened up to separate cases.The agent that was assigned to me didn't even get the code from [XXX], they just denied the claim without it.I have the emails to prove that I had to give it to her. I have.\n All my maintenance history, but as you can see from the text message from XXX Hyundai, they are requesting maintenance for a car that wasn't in my possession yet. They're asking for dates from a year before I had the car, I bought it through EchoPark. I have everyone on my side including fFdelity , as I tried to go through Fidelity and they said they couldn't approve the warranty because of the class action lawsuit against Hyundai for that exact manufacturer malfunction.

Forward crash avoidance system keeps activating causing the car to brake on it's own. This was previously fixed on my car once back in 2022 and now in 2026 it is happening again. I have been trying to communicate with Hyundai regarding additional years to current recall but their not going to even though they have known for years this was an issue and included older models than their current recall. This is not a one time issue this is the second time and until fixed it continously caused the vechile to randomly brake, it's going to get someone seriously injured or killed if they don't address it.
