All 4 Known Issues
The IVT (CVT) transmission in 2017+ Accent models can fail prematurely, with symptoms ranging from shuddering and slipping to complete loss of drive. The chain and pulley system wears, especially with aggressive driving or neglected fluid changes. Rebuilds are typically not cost-effective given the vehicle's value.
Common Symptoms
- Shuddering at low speeds
- Rubber-band effect on acceleration
- Droning noise at highway speed
- Complete loss of drive
- Transmission warning light
How to Fix
Regular IVT fluid changes every 30,000 miles (not lifetime as Hyundai suggests) using SP-CVT1 fluid. If shuddering, a fluid drain and fill may resolve mild cases. Severe cases require transmission replacement ($2,500-4,000). Given the Accent's value, a used transmission ($800-1,200 installed) may be more practical.
What Owners Are Using
Parts and tips from 350+ owners who fixed this issue
- UpgradeHyundai SP-CVT1 fluid is critical - do not use generic CVT fluid (Hyundai SP-CVT1 Fluid)
- TipChange IVT fluid every 30,000 miles regardless of what the owners manual says - this is the single best thing you can do for longevity
- NoteIf the transmission starts slipping, get it inspected immediately - IVT damage progresses rapidly once it starts
The crankshaft position sensor on the 1.6L Gamma engine in the Accent fails prematurely, causing no-start conditions, intermittent stalling, and rough running. The sensor's internal hall-effect element degrades from heat exposure near the engine block. Common failure between 60,000-100,000 miles.
Common Symptoms
- Engine stalls randomly while driving
- No-start with cranking but no fire
- Check engine light with P0335 or P0336
- Intermittent rough idle
- Engine dies at red lights
How to Fix
Replace the crankshaft position sensor (Hyundai part 39180-2B000). The sensor is located near the transmission bellhousing on the engine block. Parts cost $30-80, labor $80-150. This is a common DIY repair taking about 30-45 minutes. Always use an OEM sensor as aftermarket sensors have high failure rates.

Parts and tips from 520+ owners who fixed this issue
- UpgradeHyundai OEM sensor 39180-2B000 is only $35-45 and lasts much longer than aftermarket options (Hyundai OEM #39180-2B000)
- TipKeep a spare crank sensor in the glove box - it takes 30 minutes to replace on the side of the road and costs under $50
The rear torsion beam axle bushings on the Accent wear out prematurely, causing clunking over bumps, wandering at highway speeds, and uneven rear tire wear. The rubber bushings crack and deteriorate, allowing excessive movement of the rear axle. This is accelerated by rough roads and pothole impacts.
Common Symptoms
- Clunk from rear over bumps
- Vehicle wanders at highway speed
- Uneven rear tire wear
- Loose feeling in rear end
- Thud sound on rough roads
How to Fix
Replace rear torsion beam bushings (Hyundai part 55274-1R000 for each side). This requires pressing out the old bushings and pressing in new ones - typically done by a shop with a hydraulic press. Parts cost $40-80 for both, labor $200-400. Complete rear beam replacement is $600-1,000 if bushings are severely worn.
What Owners Are Using
Parts and tips from 410+ owners who fixed this issue
- UpgradeMoog rear torsion beam bushings are a quality upgrade over OEM rubber (Moog Rear Axle Beam Bushing)
- TipHave an alignment done immediately after replacing torsion beam bushings - the rear toe changes significantly with new bushings
The A/C compressor on the Accent fails prematurely, often between 50,000-80,000 miles. The compressor clutch bearing seizes or the internal reed valves break, sending metal debris through the system. When the compressor fails catastrophically, the condenser, expansion valve, and accumulator also need replacement to remove debris.
Common Symptoms
- A/C blows warm air
- Squealing noise when A/C is on
- A/C cycles on and off rapidly
- Grinding noise from engine belt area
- Oily residue around A/C compressor
How to Fix
If compressor clutch is failing (noise but still cooling), replace the clutch assembly only ($150-250). For complete compressor failure, replace the compressor, condenser, expansion valve, and flush the system ($800-1,400 total). Use a Denso or SANDEN aftermarket compressor rather than cheap eBay units. Always replace the receiver drier with a new compressor.
What Owners Are Using
Parts and tips from 380+ owners who fixed this issue
- UpgradeDenso aftermarket A/C compressor is reliable and half the cost of OEM (Denso A/C Compressor)
- TipWhen replacing the compressor, always flush the system and replace the condenser and drier - leftover debris will kill the new compressor
