2017 Hyundai Elantra Engine

Original catastrophic engine failure in Sept. of 2022 while exiting the highway, was able to safely leave roadway. Determined that the motor had suffered symptoms shared with models related to Recall 203. Hyundai honored "goodwill" repair, but the repaired motor began suffering substantial and sustained loss of power with evidence of cylinder scoring 1 year/20,000 miles after replacement. Secondary incident occurred while merging onto highway and required evasive maneuver to avoid collision. Car is now parked and cannot be driven due to inability to operate safely on the road. Summary of events, related correspondence to repair, goodwill repair sheet, and original purchase documentation attached.

Oil consumption. The engine eats oil and is now becoming a concern because timing is off. not to mention the numerous bills for other things going wrong now due to the oil consumption.

The engine failed without warning! The car stalled and could not be started again. There were no warning lights or indicators that the engine was having problems. The car had fresh oil and luckily I was just completing the safety check after an oil change. Had I been on the road, this could've been dangerous. The Hyundai dealership noted a seized engine with no further explanation without an extra $1000 charge. It will cost $10,000 to replace the engine that was well taken care of and only had 106, 748 miles on it.

The vehicle engine is burning oil. I found my oil pan having little to no oil and having a burnt smell to it and only 70,000 miles on the odometer. Hyundai made me pay for to have a combustion cleaning to help with the issue and would not cover it! This could have had my car blow up having no oil

I've heard that 2017 Hyundai Engines have had some recalls and looking online at others with these vehicles also experiencing same problems. Car only has 82,000 miles and now cutting off in the middle of driving under 1500 RPMs also shaking until it cuts off. Seems these cars engine warranty should cover the attached repairs as we've always done excellent service on these vehicles. I'm trying to see if there is anything I can do as we now have a $3500 repair and have to get a rental car in order to get to work.

While driving on three occasions I was driving and my car completely shut off where I had to pull over once to restart the car. The other two times I was on the freeway and had to put the car in neutral and restart the car. I almost got hit both times on the freeway when this happened.

I bought my used Hyundai Elantra 20017 in July of 2022. It's at the shop again for the same thing. While driving, it will just shut off. In traffic. My son was with me a few times when this happened, almost causing accidents. It's in the shop, second time, for engine failure! This car is crap and needs a recall on the engine before someone/ people get hurt while they are driving it.

My 2017 Hyundai Elentra Sport engine failed with 127,000 miles on it. Hyundai had a class action lawsuit for many models that guaranteed engine replacement and extended the life of the warranty to 15 years/150,000 miles. Unfortunately, it is the same issue with my model. Oil consumption issues resulting in a Blown piston. Oil was changed a week prior. Preston Hyundai confirmed that it was a Rod failure in the second piston. Paid the diagnostic fee and they put in a “Good Will claim and it was denied within 30 minutes. Preston Hyundai still has not sent me a receipt detailing their diagnostic or a copy of the goodwill claim after multiple requests. I want the record of this because the class action lawsuit that ended up protecting owners many years later

Safety concern is that the car lost power without warning while driving on 4 lane highway. My son was attempting to pass another vehicle and he noticed the hyundai was not accelerating with his foot on gas pedal. he had to coast back across the lanes of traffic to avoid being hit. Confirmed issue:The car had to be towed and Hyundai dealer states the vehicle needs a new engine. Vehicle has been inspected by Hyundai dealer no warning signs at all

Ignition coil failure. Causing misfires and rough idle. Misfire initially found in cylinder 2 when check engine light illuminated and check with an OBD II reader. Swapped the cylinder 1 ignition coil with cylinder 2. Check engine light returned the next day with the same signs. Check engine light and rough idle. OND II code scanner now says misfire in cylinder 1. The rough idle makes for slow acceleration until above 20mph.

Car has faulty engine. Have spoke to mechanics all over the state saying Hyundai Elentras have engines that are bound to die on you . Car started out stalling while driving on highway at about 85,000 miles , I bought it used at 78,000. Have replaced the vvt solenoids because this is what the engine light codes have said were the problem. I have been to hyundai dealerships and they aren't doing anything because its no recall even tho since 2017 people have been reporting this problem all over the internet . Mechanic says I have another 2,500 miles if that left on the engine even though its barely at 120,000 miles . Ive seen online people having to get new engines as low as 50,000 miles . This is a obvious problem and with Hyundai’s being a foreign car I would think the government would push for a recall on there faulty products .

When I stop at stop signs or stop lights, the car will stall out. I have to turn off the car fully, turn it back on, and immediately step on the gas pedal in order to start the car up again. This was incredibly dangerous as the first few times this happened, the stoplights had turned green, but I could not move the car. I am also afraid that the car could potentially stall in the middle of driving. The engine light has turned on and the car was inspected by Hyundai and a third party auto shop. The third party auto shop informed me that they had seen multiple models of my car with the same issue. The car is available for inspection upon request.

The vehicle has about 136,000 miles and was driving when the engine just started knocking. There were no engine warning lights or any other indications there might be an issue. We Towed the vehicle to the dealer, and they advised that it needs a new engine. We are the original owners and maintained the vehicle with regular service and oil changes.

The car engine is consuming too much oil causing the oil to run out of the car too soon. The car engine starts knocking & the car keeps cutting off.

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.

The index pin from the CVVT got stuck in my exhaust camshaft. I have replaced multiple sensors hoping those were the issue and not my CVVT and Exhaust Camshaft

The entire engine failed and threw a rod on cylinder 3. My safety has been put at risk twice since the beginning of the engine troubles. The safety issue is I was merging onto a busy highways just fine until the accelerator wasn't doing anything. So frantically I had to start checking Visuals and there were none. There weren't any warning signs of the impending doom of the engine. It would just die out of no where like someone unplugged it, but then it would start right back up. Upon Making it home safely, thankfully. I start looking at all the basics and decided to change the oil as well as it was coming due in mileage very soon. To my surprise I was a missing half of the oil I put in it last change. There are no oil puddles or marking where I park my car nor have I seen any oil leaks after driving it for a while. It's like the oil disappeared. Needless to say the oil was quite dirty looking but no metal chunks or pieces and low some how. That same night I was driving and out of no where I heard a knocking and within seconds of that mh car died/stalled/seized up. Rendering the car useless and could of been a very serious safety issue has it happened in traffic. I couldn't stare it or anything, buy luckily somehow just made it to the shoulder barely before it stopped for good. 2 questions. 1) where did my engine oil go as I know I put just under 5 qts of fresh oil in it in August and only a couple months later the issue started and I had almost been running the engine dry due to excessive oil consumption of the engine amd I never received a low oil light or anything warning on the dashboard 2) how the heck did the original brakes last longer than the not even 7 year old engine? 3) why is nothing being done to help us out as I seen hundreds of the same type of complaint. Low oil engine from excessive consumption, the random power cut offs, and the knock emanating from the same exact place as others in the engine. BigManufacturers defects

The number 3 cylinder threw a rod through the cylinder wall. Previous to this happening the car HVAC fan wouldnt turn on unless switched to the on position and waited a while then it would suddenly turn on. It also would randomly shut down, not a stall, or the engine would lose power which happened to me the first shutdown of the engine merging onto the highway creating a huge safety problem. None of the warning lights were on and the car gave no indication of what was wrong or going on. The only time I got a warning light was a after the engine threw the rod. It shut down multiple times and/or had a loss of power. The engine only has 130k miles on it. Has been well taken care of with regular oil changes. It showed 0 signs before throwing the rod and made no noise. I'm only submitting it, because I can't be the only one who had this experience and would like there to be a record of it in order to ensure the safety of others and myself on the road.

On 6/3/2022 my car stalled in my work parking lot. My coworker was behind me and had to slow down as to not hit me. I took my car to a local Service Station who services our Company's cars as driving to the Hyundai Dealer would have been too far. They told me that it was out of oil. The oil light never went on and there were no oil stains in our garage where I park my car, nor anywhere else where I parked. I had 89,210 miles on my car at that time. Then on October 20, 2022, at 99,666 miles I was driving and it stalled again. Fortunately I was at a stop sign. When I brought it to the same service station again, they said it was out of oil. Again, the oil light never went on at any time to warn me. My VIN number does not come up in any of the Hyundai safety recalls for engine related issues, nor for the extended warranty yet I have the same issues as other engines included in the recall. Additionally they will not cover the repair (my engine needs replacement) as I did not go to a Hyundai Dealer. Yet I went to the closest place when I initially had the issue and I have had bad experiences with the Hyundai Dealer by my home. I had no idea the issue was related to the powertrain warranty or that Hyundai engines had these issues or I would have taken it to a different Hyundai Dealer before the 100,000 mile warranty was up. I know that is not the focus here but rather the safety issue however I just wanted to include that information for what it is worth. Currently, I travel with the risk of my engine stalling if it runs out of oil with no warning due to the warning light never coming on to date. The only recourse is to continually check the oil. This has occurred even in between oil changes. I can provide my Service receipts as well.

On 4/3/2023, our 2017 Hyundai Elantra was taken to Bob Howard Hyundai in Oklahoma City, Oklahoma to diagnose why it kept dying after putting gas in it. It was eventually serviced on 4/17/23 by determining they needed to replace the intake camshaft oil flow control valve, as well as a synthetic oil change, including filter and gasket-engine oil plug. Almost three months later, on 8/20/23, in Tulsa, the car just stopped running suddenly, with no active warning lights, and we found it had completely spewed out all its oil! My [XXX] son could have been killed had it happened on the highway! We had it towed to Danny's Auto Repair in Sand Springs, OK. They determined the oil drain plug had completely fallen out while driving, causing the total oil loss- and resulting in the car to come to a stop, and the engine to be ruined. They documented the undercarriage of the vehicle to show there was no other damage, and after contacting our extended warranty plan we had purchased, we were told this was not covered under the warranty. Danny's then contacted Bob Howard Hyundai in OKC, explained the issue, and Bob Howard's requested the vehicle be towed to them as they would need to see for themselves. We had it towed 108 miles back to OKC. After inspecting the vehicle, Bob Howard's contacted Danny's on 9/5/23 to inform them/us, they are NOT responsible for the engine. We sent certified letters to both Bob Howard and to Hyundai Consumer Affairs, and they opened case #[XXXXXXX]. They said Bob Howard would have to address the issue & they would follow up with them. They did, and Bob Howard again said not responsible. We reported to Better Business Bureau, and have left a message for an attorney to review the circumstances. Then today researched several Hyundai lawsuits about this same issue hundreds of other customers have had. Nothing has been done. Hyundai won't take responsibility.
