Alarming rate of oil consumption causes sudden loss of power / acceleration which definitely increases probably of causing an accident. Local repair shop confirmed extremely low oil level with no evidence of where oil went shortly after oil change and annual safety inspection. All the dashboard warning lights came on when it happened but low oil warning light came on prior to event. No warning whatsoever, just sudden loss of power and completely lit up dashboard.

My hyundai elantra is a lemon. I have been having accelerating problems, stalling problems fresh from the lot even before 5,000 miles with my hyundai not accelerating took it to dealer said nothing is wrong with it 5 years ago. It still continues to stall on me! It broke down on me twice in two days in a row. One on 8/8 and 8/9! Could have killed me or others if I took it on the highway. My car has been stalling and I had to pump the break to rev up the engine at the same time while turning! Could have killed us! I am sitting in a lemon! It is not safe on the road at all!! I lost my job because of this and the time it took me to try and get a rental. Hyundai won't let me get a loaner car! I cannot afford uber all the time. All the lights are on. Check engine light too and airbag light. My transmission seems to be slipping too and the double clutch. Crank and cam shaft problems! Headlightw are very dim too. Airbag weight front seat sensor is turning on. Engine is stalling. Slows down! Will not accelerate after 60mph goes super slow down to 55 MPH up hill. I want hyundai manufacturer to pay or I am getting a lemon lawyer and contacting the bbb and the state of arizona.

UNKNOWN- intermittently - multiple times a day for the last month the car starts making clicking noises like a card in the spokes of a bicycle. Mechanic could not find the cause. UNKNOWN- two times in 2 weeks- while making a turn my car stalled in the middle of an intersection, all the lights on the dash went on, and wouldn't start up again for a couple minutes. Then car starts and runs fine besides the intermittent clicking

Engine completly stalled while driving, was parking in a parking garage, and was driving up on an incline to park and my car just stalled and all warning lights came on. No warning lights were present prior to, and all power was still on. I was stuck in the middle of the lane, blocking cars in. I was able to turn the car off and restart it and it started up with no warning lights and as if nothing just happened. I do not feel safe driving this car and will be having it inspected immediately

In regards to my 2018 Hyundai Elantra Limited currently with 47000 miles, driving and noticed the a/c temp display which also controls fan speed stopped working, display was blank. Checked all other electrical equipment inside car with no problem except that the heated seat function didn't work also.while doing an exterior inspection noticed that all lights except the headlights worked.After the interior and exterior inspection and no error codes or indicators on the dash, I had the alternator, battery and starter checked along with probe testing every fuse in the car and under the hood checked and everything was fine. The Car has been perfect up to this point which is alarming because if the headlights go out while driving at night or in the rain this is a safety problem and driving citation. My only indication of when this happens is if the a/c control display goes out. The problem is intermittent and Hopefully it won't happen again and I couldn't find any other similar things like this happening to others.

While driving the vehicle this past January, I experienced a brief “clunking” noise in the engine, and the car stalled. The check engine came on briefly and then disappeared. The code identified was a “faulty crankshaft” code. I made an appointment with the dealership to take it in to be inspected, but later that day my son was driving to pick me up from work and the vehicle literally died in the middle of an intersection. No warning, all lights came on in the vehicle, the electrical system terminated, and the vehicle died. I had to have it towed to the nearest garage, which was a Pep Boys, and they diagnosed the problem as an alternator and battery, serpentine also. So. 1300 dollars worth of work later…. Turns out the car has an engine issue.
