2019 Hyundai Elantra: excessive oil consumption

Filed Jul 23, 2026 · Engine · NY

The engine failed for my 2019 Hyundai Elantra. We bought it at Atlantic Hyundai dealership. They used a passing recall inspection to clear a defective engine, misdiagnosed the ensuing failure as an oil pan leak, and abandoned me with a vehicle that stalled dangerously in traffic. We brought car to Atlantic Hyundai told them that the car just stopped on the highway in the middle of driving. Our mechanic told me to tell Hyundai the car was rapidly consuming oil. Hyundai said oh no it’s just an oil pan snd we trusted them allowed them to fix it. Several weeks later the car completely stopped in middle of driving on exit ramp. Police came to make sure traffic was diverted so they could help me get car to side of road safely. It was towed back to my mechanic who said same exact thing car is dangerous bring it to Hyundai they need to fix this for you it’s the engine recall. We had it towed to dealership and after 2 weeks they said oh yeah you need new engine. We brought it to independent mechanic because Atlantic Hyundai knowingly sent me off in a dangerous vehicle the first time and no longer did I trust them with safety of myself and others on the road

The car was driving on the highway and out of nowhere the car just stopped in the middle of the highway. I brought it to my mechanic who said the car was rapidly consuming oil and my cars engine was seizing. and he safely brought me and the car to Atlantic Hyundai where I had bought the car to have them diagnose and fix the issue. After several days they diagnosed the issue as a simple oil pan issue and replaced the oil pan and sent me on my way. The same issue with the engine seizing up in the middle of driving on the highway endangering my life and others. I am still terrified thinking of this. We brought car back to Hyundai by tow truck because I was scared to drive it and after 2 weeks of waiting they then told me the car needed new engine however they never mentioned what I later discovered was a serious recall for this specific engine . Upon further research my car was listed under the recall however before I bought the car it says it passed the test to see if it needed engine replacement under recall 203 . They knowingly said my vehicle was safe they sold it to me knowing it was unsafe and then they put a bandaid ( oil pan) and sent me on my way knowing I was in danger. I am lucky to be alive because the car stalled out on a major highway .

2019 Hyundai Elantra (VIN: [XXX]) suffered engine failure at 152,061 miles — abnormal knocking, loss of power, towed to Clay Cooley Hyundai of Sherman, TX. Diagnosed with crank/rod knock requiring long block replacement. This is the exact failure progression documented in the federal safety agency Recall 21V301 (Hyundai Recall 203): defective piston oil rings causing cylinder bore scuffing, accelerated oil consumption, connecting rod bearing failure, and engine block damage. Coverage was denied solely due to mileage — 2,061 miles beyond the 150,000-mile threshold. I am also reporting a critical discrepancy: a VIN search on the federal safety agency's website shows zero open or unrepaired recalls on this vehicle, despite the following facts: 1. This is a 2019 Elantra with a 2.0L Nu MPI engine — the exact population covered by 21V301. 2. The vehicle experienced the exact failure mode 21V301 was issued to address. 3. The dealership repair order references TSB 25-01-054H (tied directly to Recall 203) and performed an ECM software update under that bulletin during this visit. It is unclear whether this VIN was improperly excluded from the recall population, or whether the recall was marked remediated based solely on the software update — despite the engine already having suffered catastrophic internal damage. Either outcome warrants investigation. I am requesting the federal safety agency examine whether this VIN should have been included in 21V301, and whether Hyundai's practice of applying a software update to an already-failed engine and closing the recall is consistent with the intent of this safety recall. Repair estimate: $9,245.58. Vehicle is undrivable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Engine failure. Less than 150,000 miles and engine has gone bad. Burning oil, and loud noise when car starts. Had multiple mechanics look at the car whom said the motor went bad. I’ve been consistent with oil changes, tune ups, etc. maintained the car well so I don’t know why or how this happened.

Engine burning oil

My 2019 Hyundai Elantra sel had catastrophic engine failure at 95k. I was riding at 40mph on the highway when the engine failed. It had zero warnings lights whatsoever before it happened. I was barely even able to make it off the road. I had it towed to the dealer. They said it was a rod bearing. My catalytic converter also failed. They said I was burning oil which again had no idea I was since I didn’t smell it nor did I have an engine light. However the dealer said my vin wasn’t part of the recall.

The Knock Sensor Detection System (KSDS) software malfunctioned by failing to detect abnormal vibrations or knocking sounds. As a result, there was significant internal engine damage that caused the vehicle to seize unexpectedly in the middle of traffic on 4/10/25. The car started and abnormal noises were noted from the engine though not significant. week later, car stalled several times on interstate. Prior to the failure, the vehicle exhibited a progressive knocking noise in the engine. After seizing, the vehicle would struggle to start, idle briefly, then stall. It also randomly shut off while driving, creating a serious safety risk. The vehicle was taken to Precision Tune Auto Care, where technicians confirmed problems with the crankshaft, excessive oil consumption/leakage, and metal shavings in the oil, which they attributed to rod bearing and crankshaft wear consistent with Hyundai Campaign 203 (improperly heat-treated piston rings). Despite the KSDS being installed during the initial recall remedy, the system did not activate prior to engine failure. Additionally, no engine or oil warning lamps were illuminated. An oil change was performed at the time, but the vehicle had already burned through excessive amounts of oil since the prior change. Precision Tune Auto Care advised me to take the vehicle to Allen Turner Hyundai. At the dealership, staff confirmed issues with the engine but refused to acknowledge Recall Campaign 203, even when presented with documentation. They also failed to address the malfunctioning KSDS system or the lack of functioning engine/oil warning lamps. They were asked to perform inspection relating to piston ring and rod bearing, though refused. This situation raises major safety concerns, as my engine seized in the middle of traffic without warning. Other owners with a malfunctioning KSDS system could face the same risks, leading to sudden engine failure, potential engine fires, or serious traffic accidents.

Engine light is on. Noticed engine shaking and burning of engine oil. Checked by Hyundai dealership who states engine EXHAUST CVVT AND CAMSHAFT needs to be replaced which is the engine timing chains. The engine is burning oil quickly which could indicate damaged piston rings as well. It is an extreme safety risk as the engine smokes and can cause a fire! Car has been regularly maintained with oil changes being done twice a year at Cocoa Hyundai
