2017 HYUNDAI ELANTRA Complaints

The car randomly dies on de-acceleration. It gives no warning and I have seen online this is a known issue with this year/model. I have 55,000 miles on it, it's been regularly serviced. When I got to slow down then start to accelerate it shuts off. I've nearly been hit multiple times going to merge from a stop. It's very dangerous. I've replaced all 4 spark plugs, all 4 ignition coils, air filter, cabin filter, oil filter, PCV valve and I've only owned it 6 months. No engine light comes on and no reader is picking up any codes. I'm at a loss as to what causes this.

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.

My car has been dying while on the road when I'm slowing down. I have spent $2,700 to get this issue fixed, and after replacing everything the computer said was wrong, the auto shop has determined that the issue is, in fact, the computer itself. There is nothing left to fix, but the car still will completely shut down while driving. Not safe at all, especially since I live in a high traffic area. There are no warning signs before the car shuts down, but lights do show up on the dash when it has shut down. The check engine light, oil light, and battery light come on.

The contact owns a 2017 Hyundai Elantra. The contact stated while driving to the emergency room at approximately 50 MPH, the vehicle began to lose motive power and the contact had to pull to the side of the road. The contact stated that when the vehicle was restarted, there was a knocking noise coming from the engine. The contact continued to drive the vehicle to the emergency room, and after leaving emergency room when the vehicle was started, the knocking sound continued. The contact stated that while coming to a stop light, the oil and check engine warning lights illuminated. The contact drove to a nearby gas station where 2.5 quarts of engine oil was added to the vehicle however, the engine continued making the knocking sound. The contact discovered an unknown NHTSA Campaign related to the engine however, the VIN was not included. The vehicle was taken to the dealer where it was diagnosed with Low Oil Pressure, Low/No Engine Oil, Lower End Rod Block, and the dealer recommended that the engine be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and a case was opened. The failure mileage was approximately 131,000.

My passenger doors will not open from outside or inside when it is unlocked. It sometimes open when it wants but it causes trouble if I would have to get out of the car.

My car has been stalling shortly after purchasing when slowing down and turning. Then it started stalling on the freeway which is a safety big time issue multiple times. Dealership spoke of maintenance they said it needed. They changed a part and parts on my car has been changed multiple times it doesn’t make since.

When driving about a month ago my car all the sudden started making a clinking noise not so much knocking in the engine or near the engine. And then it died all the sudden at a red light out of no where. Well I put the car into park and started my car again when I accelerate the rpm takes a lot longer to catch up to the speed I'm trying to go, so it takes longer to accelerate which is dangerous because cars usually accelerate alot faster than that and I almost got rear ended twice because of it. I parked it for a few days but moved recently so I had to move the car it started and everything but the knocking, or clinking was still there. The following day I went to start my car and know it won't even start and the anti theft light comes on, on my dash board. So now my car is stuck at a motel because of it. I think it may be the crank shaft position sensor. Yes my vehicle is available for inspection upon request. No my vehicle has not gotten in any accidents. It has not been inspected by a manufacturer.

Right Rear Door (Right rear passenger) will not open. all other three doors open and close. Right rear door will not unlock to open. This is a safety concern.

Entire engine needs to be replaced due to cylinder malfunction. My safety was at risk because the car would turn off randomly at red lights or when making wide turns. Sometimes, the car would not start and sometimes it would. The problem has been confirmed by an independent service center. No messages or lights appeared indicating an engine issue.

The Issue started back in December of 2023.The Engine failed while driving to Lake Worth, TX. Vehicle Information: Model is a 2017 Hyundai Elantra Limited 2.0 Engine, US Built. Mileage during the1st incident was at 100,125 miles and the VIN Number is [XXX] . I was on a Maintenance plan the first 2 years with Clay Cooley Hyundai of Dallas with Dealership Warranty when I first purchased the vehicle back in 2017 so I kept up maint.Stalling began & was making a significant tapping noise.Dgnstcs were performed and I initially got Misfire codes P0303, P0300 &P0301. Ignition coils and sprk plugs were observed and replaced. Instantly following I ran another diagnostic and began receiving Camshaft codes P011.The VVT Solenoids were also replaced and this still did not resolve the issue. I was losing oil after every oil change and the oil was not lubricating the engine. I then took to a local shop and they said engine was beyond repair and had it towed to dealership. loud knocking noise from the engine that increases in frequency as the engine rpm increases. Then there is Reduced power and/or hesitation and vibration. With these issues the Illumination of the “check engine and Engine Oil Pressure” light come on in the instrument cluster. Safety Concerns: Stalling and Shutting off of the engine while driving at accelerated speeds is a Dangerous Manufacturing issue that could have resulted in a major car crash not only jeopardizing our safety but the safety of other drivers. Similar Incidents: There have been several reports and forums that we have read that report the same issues with their Elantras. Impact on You: This has impacted me Tremendously as the Dealership states that they cannot assist with the Damages and that I would have to come of pocket by paying over $8,000 to replace the engine. Financially this is beyond my means in what I can afford and stalls my primary source of transportation for commuting back and forth to work, taking care of day to day priorities.
