Engine
My engine has almost completely burned through its oil twice. I have done routine oil changes and maintenance on the vehicle and the first time this happened, I had driven 3,000 miles since my last oil change (full synthetic, so it should be able to go up to 5,000 miles). The second time, it was out of oil at 1,200 miles. I took…

My engine has almost completely burned through its oil twice. I have done routine oil changes and maintenance on the vehicle and the first time this happened, I had driven 3,000 miles since my last oil change (full synthetic, so it should be able to go up to 5,000 miles). The second time, it was out of oil at 1,200 miles. I took the car to Hyundai after the first incident and they said no error codes came up, so there was nothing they could do. This safety issue could cause my engine to stall mid drive, causing a potentially fatal accident. There are no warnings that the engine is low on oil, making this an even more alarming and dangerous defect. Hyundai will not help consumers with this issue, and there is a class action lawsuit against them right now for this problem. Many are saying the exact same thing happened when taking the vehicle into the dealer; they were turned away and charged for no help. I was told to just keep putting oil in my car, but it has gotten exponentially worse since this all began.

Engine
88,750 miles - Engine began profuse knocking suddenly when traveling down the road under 50mph. Stopped at a service center and they found no oil in the engine. Like THOUSANDS of others with the same complaint, the engine burned the oil which caused it to destroy itself LONG before the oil change interim had arrived.

I believe it is the transmission/ power train that failed. It slides gears and the engine stalls. While driving, I was almost hit because I could not speed up. I had to decelerate in order for the gear to not stutter.

Engine
At 75,000 miles my engine randomly blew on the freeway, I rolled down the off-ramp where I lost all power and had to put it in neutral and put the emergency brake on so I didn’t roll through a red light at the bottom of the ramp. Absolutely no warning, nothing else was wrong with the car, mechanic said oil and everything else lo…

At 75,000 miles my engine randomly blew on the freeway, I rolled down the off-ramp where I lost all power and had to put it in neutral and put the emergency brake on so I didn’t roll through a red light at the bottom of the ramp. Absolutely no warning, nothing else was wrong with the car, mechanic said oil and everything else looked perfect but that it was a manufacturer defect due to the pistons in the engine. Now I owe 8.5k on a car I can’t drive because neither insurance nor Hyundai will take responsibility. Great 👍🏻

On 06/10/2022 Going down the road went to shift gears and it was stuck in 5th gear. Finally got it released and safely made it home. Ever since you can shift the gears and reverse while engine isn’t running but once I turn on the vehicle it refuses to shift into any gears including reverse. I have a FIXD OBD2 sensor and it showed no warning messages before, during, and now. No codes are showing up when plugged in. Matter of fact it says there’s no issues with my car ? I had a mechanic take a look since he was willing to come to my house considering I currently don’t have the funds to get it checked out & he said it’s probably my clutch has went out, but that can’t be the case considering it will turn on still. I have no messages appear on the dash & I have plenty of transmission oil. Today is 07/08/2022 and it has just been sitting there due to the fact I’ve lost my employment and can’t afford to have it looked at

The paint is peeling off my Hyundai Elantra and I only have 28000 miles on it. It started peeling 2 years ago. I can supply pictures. I visited my local Hyundai dealership, where I bought the car, they made me wait for an hour then told me there was nothing they could do. I noticed someone scratched the paint with a fingernail from their workshop. I also called the Hyundai corp and they said there was nothing they could do.

1DP21003 · Throttle Control System Vulnerabilities
Opened Nov 12, 2021 · Closed Jun 20, 2023
Status: closed (inferred from source dates) · Vehicle Speed Control:throttle
The Office of Defects Investigation (ODI) of the National Highway Traffic Safety Administration (NHTSA) received a petition letter dated October 10, 2021, requesting an investigation of possible defects in the electronic throttle control (ETC) system on certain Kia vehicles resulting in the opening of DP21-003. Accordingly, Model Year (MY) 2005-2016 Kia Optima/K5, MY 2006-2015 Kia Sorento, MY 2007-2016 Hyundai Elantra, MY 2007-2016 Hyundai Santa Fe, MY 2006-2015 Hyundai Sonatas are all part of the subject population. The petition was originally filed as a Vehicle Owner Questionnaire that can be reviewed at NHTSA.gov under reference (ODI) number 11439675.On November 12, 2021, ODI opened Defect Petition DP21-003 to evaluate the petitioner?s request. ODI performed trend analyses of the VOQs related to vehicle speed control issues for all the subject vehicles and found that none of the 52 Model/Model Year Hyundai/Kia vehicles demonstrated any actionable trend that warranted an investigation.Petitioners submitted 1119 VOQs and non-VOQ cases in which sudden uncommanded acceleration (SUA) or loss of motive power (LOMP) incidents were alleged.For the 1119 reports, 220 were incidents involving crashes, from which 69 subject Hyundai-Kia vehicles were inspected by Hyundai/Kia dealer technicians, Hyundai/Kia engineers, and/or third-party representatives.ODI found the inspections identified no vehicle defects related to the ETC system.Of the 220 crash-involved reports, 13 Event Data Recorder (EDR) records were downloaded successfully and 11 of those indicated driver error: (i.e.) pedal misapplication.A condition where the accelerator pedal is mistakenly applied instead of the brake pedal when the driver wants to stop the vehicle.In addition, ODI reviewed a scientific journal paper published in Forensic Science International in 2016 by Mr. Park et al ., as well as related test videos. ODI does not believe there is any evidence of uncontrollable SUA occurrences in any of the tests reviewed. NHTSA's Office of Vehicle Safety Compliance (OVSC) reviewed the allegations regarding the potential noncompliance with Federal Motor Vehicle Safety Standard No. 124.Based on the information provided, the Agency concludes there is insufficient information for us to determine if a possible non-compliance exists.Finally, both Hyundai and Kia informed ODI that all their vehicles manufactured after 2012 were equipped with an ETC management system, in which the engine speed will go to idle when the system sees signals from both the brake pedal and accelerator pedal at the same time; this is commonly known as the brake-throttle override system.After thoroughly assessing the material submitted by the petitioner, information already in NHTSA's possession, information submitted by Hyundai and Kia in response to an Information Request letter, and the potential risks to safety implicated by the petitioner's allegation, NHTSA does not believe that a formal investigation is warranted. After full consideration of appropriate factors, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA?s reasons for denial of the petition will be published.
