2020 Hyundai Elantra

I got this car right at the beginning of 2020, I didn’t even KNOW HOW to use my high beams until 2-3 years in. I used them all of 4-6 times and they magically stopped working. I don’t need them often so I didn’t notice right away. I’ve known for a while now but didn’t know I could submit a form like this. And no way in hell am I paying that much money for something that broke after a few uses. I’ve heard this is very common for my car make and model; I can hear the doors of the light trying to switch open but they’re stuck or something… I’m definitely not the only one having this issue…

Cruise control on 55mph, car has slowed down going straight no uphill or downhill and accelerator did not work nothing blocking the accelerator. Had to pull over to a shoulder to shut engine off and on to drive. Tapping cruise control up to speed up in regulated area such as from 55 to a 65mph zone.. cruise control speed lowered. Attempting to speed up with accelerator still only slowing down. 3 times this year I had to change spark plugs within a 6 month period Error code p0302. Replaced battery alongside. Continues p0302 code. Replaced all coils and spark plugs still p0302. Climbing uphill vehicle sometimes looses power that happened twice in 2025 and twice in 2022. 3 times in 2024. That i must turn on hazards and floor the accelerator to gain speed on up hills in neighborhoods going 25 mph. I have dropped to 10 mph. I get oil change regularly. Always when due. Every few months I make sure to get a full car inspection to make sure everything is in proper working order.

At around the 120K mile odometer reading check engine light came on and upon checking the oil, noticed it was 1/2 qt. down in spite of a recent oil change. There were no other issues apparent to our mechanic. At the next oil change, we asked the techs to be sure to tighten the oil pan and all components as we mentioned the drop in oil after the previous oil change. This time, only 10 days after the oil change (we have been using hybrid blend since purchasing the vehicle new), the check engine light went on again and the oil was down a quart with no signs of leaking. Our mechanic checked it again and told us of many Hyundai oil consumption issues and suggested we check for a recall. My vehicle was not included in the oil consumption recall despite having the same year, model and engine as many of the other "certain" vehicles. We are currently negotiating a solution with Hyundai Motor Corp.

Engine blew up on the highway almost causing an accident. The car has had problems with rapid oil consumption since 20000 miles on the car. Always checked oil everyday and added oil when needed and regular oil changes every 3000 miles car was very well taken care of. No oil light or check engine light came on when the engine blew up.
