What stands out
Engine accounts for 21% of all owner complaints filed against this vehicle, across 5 categories tracked.
No new NHTSA engine complaint has been filed on this vehicle in over 5 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Follow the guidelines outlined in this bulletin to inspect and clean or replace certain components of the engine intake system accordingly during engine short block or sub-assembly replacement.

The failure pattern owners describe
Fourteen owners of 2017 Hyundai Accents describe a severe pattern of premature engine failure tied to rapid oil consumption. Multiple complaints note that oil dipsticks show little to no oil within weeks of a service interval—one owner checked oil daily only a month after a scheduled change and found "nothing but fumes." These low-oil conditions accompany ticking or knocking noises, burning smells, and stalling without warning, sometimes in traffic, creating dangerous situations.
The excessive oil burn destroys catalytic converters; three separate owners report replacing the same converter two or three times before finally giving up. One owner replaced it three times and suspects the pattern will continue. At least one mechanic confirmed rod bearing damage; another noted low engine compression on a repeat failure. Several complaints mention GDI engine defects, with mechanics telling owners that the problem is well-known but Hyundai avoids acknowledging it officially.
Hyundai's response is consistent: no recalls, warranty denials citing insufficient maintenance records (despite owners producing oil-change receipts), and refused corporate assistance. One owner's goodwill request was denied via email with no phone explanation. Failure mileage ranges from 80,000 to 138,400 miles—some within the standard powertrain warranty period, yet coverage was withheld. Anecdotal reports suggest engine replacements happen in some regions but remain inconsistent and difficult to obtain.

Failure modes owners describe
Excessive oil consumption / low oil condition
Engine consumes oil rapidly despite recent oil changes; owners find little to no oil on dipstick within weeks of service, damaging internal bearings and catalytic converters.
When: 80,000–138,400 miles; occurs within weeks to months after oil changes
Symptoms owners cite: No oil or only fumes on dipstick after recent oil change; Ticking/knocking noise from engine; Burning smell; Check engine light illumination; Multiple catalytic converter failures (some owners on third converter)
Codes mentioned: Check engine light (unspecified codes), Oil warning light
Repairs/costs cited: Rod bearing damage confirmed in at least one case; some owners replaced catalytic converters multiple times ($2,500+ in one case); some dealers replaced entire engines but availability and approval unclear
Recalls/TSBs owners mention: No official recall acknowledged by Hyundai as of complaint dates. Anecdotal reports that some owners in certain regions (New Hampshire mentioned) received engine replacements outside warranty via unconfirmed 'goodwill.' Hyundai corporate refused to take information from owners; warranty denials citing insufficient maintenance records despite documented oil changes.
Sudden loss of power / stalling
Engine abruptly loses power and stalls while driving, often at low speeds or in traffic, creating hazardous situations. Vehicle may restart but may not accelerate normally or may stall repeatedly.
When: Throughout ownership; mileage ranges 80,000–138,400 miles
Symptoms owners cite: Complete loss of power while driving; Stalling without warning; Inability to accelerate above 5–15 mph after restart; Sputtering, shaking, hesitation; Check engine light illumination (sometimes delayed or absent)
Codes mentioned: Check engine light, Camshaft out of sync (reported in one case)
Repairs/costs cited: One owner reported replacement of engine cylinder and catalytic converter; low compression diagnosed in follow-up; second stall event occurred months after initial repair. Other owners did not receive diagnosis or repair.
Recalls/TSBs owners mention: Claims filed by at least two owners were denied. Dealer offered no assistance in at least one case.
Engine knocking / internal bearing failure
Abnormal knocking or ticking noise from engine; diagnostics confirm rod bearing damage or low compression, indicating internal engine wear or manufacturing defect unrelated to external catalytic converter failure.
When: 80,000–118,000 miles
Symptoms owners cite: Audible ticking or knocking noise from engine; Noise present during acceleration or at idle; Check engine light and/or oil warning light; Vehicle stalling during or after knocking onset
Codes mentioned: Check engine light, Oil warning light
Repairs/costs cited: Rod bearing replacement quoted; compression replacement noted in dealer service for one owner; no successful repairs reported by owners
Recalls/TSBs owners mention: No recall or warranty coverage confirmed. Hyundai corporate complaint filed but no follow-up received in at least one case.
Engine misfire / acceleration hesitation
Engine misfires, hesitates on acceleration, or jerks intermittently; owner reports multiple shop visits with no root cause identified beyond 'engine misfire' warning light.
When: Throughout ownership; one case at ~80,000 miles
Symptoms owners cite: Jerking during acceleration; Slow initial acceleration; Engine misfire warning light; Multiple failed repair attempts with no diagnosis
Codes mentioned: Engine misfire code, Check engine light
Repairs/costs cited: One owner reported issue 'fixed' at dealer/CarMax but problem persisted; multiple shop visits without root cause identified
Recalls/TSBs owners mention: No warranty coverage or recall confirmation in narratives.

In october of 2020 the car had an oil change. About a month later while driving down the highway I started to hear a ticking noise. When I got to my house we started to investigate what was going on. First we checked the oil which was nothing but fumes but the oil light never came on. Confused as to why there was no oil we kept investigating because as stated before the car had an oil change the…

Like many of the other complaints, in 2 years I have now replaced 3 catalytic converters. Everything will be fine and then BAM car stops working. No one can find any other issues. The car is in the shop again after the engine misfire light came on. Let’s see what it is this time. I am guessing it is an engine problem but no matter how many times I look, there are no recalls. Not sure what…
I had two different mechanics I trust tell me that this car has a particular engine that had an error in manufacturing, but Hyundai didn't correct it, because it would cost them too much. The error is heavy oil burning, such that it destroys the catalytic converter. I am now on my third catalytic converter in this car, and the check-engine light is beginning to flicker. Mechanic recommended…
This car has a GDI engine, which is now known to be defective due to excessive oil consumption. I bought the car used, with Hyundai's certified inspection before selling it to me. While my daughter was driving the car on the highway, the engine suddenly balked and stopped. She pulled over to the side of the road and called for assistance. As I write this, there is still no recall on anything…
Vehicle lost power in traffic, stalled and wouldn't restart without constant and repeated attempts. Place consumer is dangerous situation for rear collision. Vehicle restated but would not engage to where acceleration would occur above 15 mile per hour, sputtering, shaking and hesitating. Vehicle had to be towed where mechanic determined Computer code Cam Shaft out of sync. The vehicle is not own…
I purchased my car in February I was told everything was fine, my car does this jerking everytime I drive sometimes acceleration is slow at first I took my car to carmax and was told the issue was fixed unfortunately my car is still having this issue it’s upsetting because this is my first car & I shouldn’t have this issue when it was supposed to be fixed before my warranty ended.
