to whoever it is that can help, I am reaching out to submit a formal complaint regarding my 2017 Hyundai Elantra due to ongoing mechanical and structural issues that began very shortly after I purchased the vehicle, which have progressively worsened. I made the purchase in January 2024 for approximately $13,000 with 60,000 miles. The vehicle now currently has approximately 108,000 miles. Since purchasing the car, I have experienced consistent time consuming and serious issues that I believe indicate defects in manufacturing or design. First, the thermostat had failed during the first winter season I owned the Elantra, despite replacement the vehicle’s heating system still does not function properly. I’m not a fan of the cold. Also, the engine burns oil at an extreme rate. I am required to add oil literally every 2–3 days to prevent the engine from running dry, which presents a serious risk of engine failure and potential safety hazards while driving. And is also costly as oil is not cheap. In addition, the vehicle’s headlights developed spiderweb pattern cracking and shattered from the inside after approximately nine months of use, without any external damage. The paint has chipped across the vehicle, including in door jambs and other protected areas, suggesting poor paint quality. And recently, the lower engine underbody cover has completely broken down and disintegrated over time due to clips constantly falling out. Given the age of the vehicle and the normal use, the amount and severity of these issues are unacceptable. These defects have caused significant financial burden and raise serious concerns on vehicle safety and manufacturing quality. I am requesting that this complaint be reviewed for potential defects or recalls. I would also like Hyundai to be held accountable, either through compensation for the repairs required or replacement. Thank you for your time and attention to this matter. Sincerely, Owner of the 2017 Hyundai Elantra

Car will lose power and quit suddenly on the highway with no warning lights. It has happened twice in the last month on a trip both times. Light’s low beam randomly won’t turn on either but high beams work. Had it into the Hyundai dealership and another mechanic shop but cannot find the problem.

Driving at 70mph, another vehicle that is sitting on the grass on the side of the road decides to pulls out in front of me as I'm approaching(no warnings occurred from the collision assist system). I swerved to avoid the other vehicle and then he decides to pull into the lane that I'm trying to get into to avoid him. I break hard but not hard enough to lock the tires up or set off the ABS. Moments after that incident, faults begin to pop up on my instrument cluster, Check Lane Departure Warning System(LDWS), Check Autonomous Emergency Braking System(AEB) and Check Smart High Beam System. I figured that since some of these are safety related that I should report it. My vehicle has approximately 38000 miles.

Receiving intermittent warnings to check Automatic Emergency Braking System, Lane Departure Warning System, and Automatic High Beam Light System. All three warnings occur together and happen intermittently while driving. Problem may or not begin when first start driving. The problem will also seem to rectify itself after a period of time then begin to cycle again several minutes or hours later. Will occur at any speed or while idling.

When driving at night, sometimes the headlights and taillights will shut off leaving the car totally in the dark. This is a SEVERE SAFETY ISSUE as you can no longer see the road and other cars cannot see you. The problem appears to possibly be associated with the light switch, as you can jiggle it and get the lights back on. Also related to this problem of the lights shutting off is the fact that occasionally the lights will come on long after the car has been parked in the garage, which tends to drain the battery. After experiencing this problem, I checked the internet and found numerous other cases of Hyundai Elantra owners reporting the exact same symptoms, so it seems to be a somewhat generic problem. Hyundai’s service department has been unable to isolate the problem on my car. The problem happens randomly and is infrequent but serious when it happens. It has happened approximately 10 times over the past two years.

Bought 2017 Hyundai Elantra in May 2020 car had no paint peeling at Odometer reading 82,888. In October 2020 the paint on the hood of the car near the headlights started peeling the odometer reading was about 92,897 at that point. A couple months later the roof next to the windshield start peeling too. Now those spots have grown each time it rains. These spots are now starting to rust. Obviously this is bringing down the value of the car. Not to mention it makes the car look terrible. After I bought the car I went out and put new tires and wheels on it plus other accessories to make it stand out only to have the paint start peeling and have it look terrible. As a consumer I should not have to pay for Hyundai mistake in painting thier cars incorrectly.
