Hyundai's entry-level crossover in its simplest form. The 1.2 MPI uses a naturally aspirated four-cylinder with port injection and a timing chain, making it one of the least complex new cars sold in Europe. Paired exclusively with a 5-speed manual, it avoids the turbo, GPF, MHEV, and DCT issues that affect the 1.0 T-GDI Bayon. Backed by Hyundai's 5-year warranty and competitively priced, it targets buyers who prioritise low running costs over performance.
5-year unlimited-km warranty
Very simple, low-maintenance engine
Underpowered at 84 hp
Front brakes wear quickly
Buy if: You want the cheapest possible crossover to own, do mixed or urban driving, and prefer mechanical simplicity over performance.
Avoid if: You need motorway performance or plan to carry heavy loads regularly, as 84 hp is marginal for sustained high-speed driving.

Common Problems
Front brake discs show above-average wear, with squeaking or vibrations often appearing after 25,000 km · more· less
The Bayon's front brake system is a documented weak point across all engine variants. Owners report squeaking, pulsation when braking, and visible disc scoring appearing as early as 25,000 km, with many requiring disc and pad replacement by 40,000 km. This is unusually early for a light crossover. Contributing factors include the relatively thin front disc specification and the car's regenerative-braking-style engine braking behavior that loads the front axle. Hyundai developed an updated brake pad compound to address the issue under warranty. When replacing outside warranty, budget for discs and pads on the front axle: approximately 150-250 euros at an independent shop with aftermarket parts, or 250-350 euros at a Hyundai dealer with OEM parts. Rear brakes are not affected to the same degree.
EPS motor or steering angle sensor can fail, causing heavy or erratic steering, typically after 50,000 km · more· less
Electric power steering issues are a known concern across several Hyundai small car models. On the Bayon, symptoms include the steering becoming unexpectedly heavy at low speeds, sudden lightness, or intermittent assistance loss, often accompanied by the EPS warning light. The steering angle sensor is the most frequent failure point, but the EPS motor itself can also fail. A sensor replacement or recalibration at a specialist costs 300-500 euros. If the EPS motor or complete column assembly needs replacement, costs rise to 800-1,200 euros at a dealer. The issue affects a relatively small percentage of cars, and Hyundai has acknowledged it on certain VIN ranges. The problem can appear suddenly without warning, which makes it a safety concern worth checking during a test drive.
Front radar sensor loses calibration or gives false warnings, requiring recalibration or replacement · more· less
The Bayon's forward collision avoidance assist system (FCA) is reported to malfunction periodically, displaying the 'Check driver assistance system' warning. Common triggers include dirty or obstructed radar sensors (rain, snow, road grime), temperature extremes affecting the front camera, and minor sensor misalignment from speed bumps or kerb impacts. In most cases, the system resets itself after the ignition is cycled, costing nothing. Persistent faults require sensor recalibration at a Hyundai dealer (100-200 euros) or, in rare cases, sensor replacement (300-500 euros). This is an annoyance rather than a mechanical reliability issue, but it occurs frequently enough across the Bayon range to be worth noting.
Chain tensioner can weaken at high mileage, causing cold-start rattle if oil changes are neglected · more· less
The Smartstream G4LA 1.2 MPI uses a timing chain designed to last the engine's lifetime. The hydraulic chain tensioner maintains correct tension via engine oil pressure, but can weaken over time if oil changes are neglected or if incorrect oil is used. This produces a brief metallic rattle on cold start that disappears within a few seconds as oil pressure builds. On the G4LA engine, this typically does not occur before 120,000-150,000 km with proper maintenance. If ignored, the chain can eventually skip a tooth and cause catastrophic valve damage (interference engine). Preventive replacement of the chain, tensioner, guides, and sprockets costs 500-800 euros at an independent shop or 800-1,200 euros at a Hyundai dealer. Regular oil changes every 15,000 km with the correct specification are the best prevention.
Touchscreen occasionally freezes or goes black, typically resolved by a system restart · more· less
The Bayon's infotainment system can experience intermittent freezing, unresponsive touch input, or a black screen while audio continues to play. This appears related to software stability rather than hardware failure and occurs across all Bayon variants. Connecting a phone via Apple CarPlay or Android Auto during system startup seems to trigger freezing more frequently. In most cases, a long-press of the power button for 10 seconds forces a reboot and resolves the issue at no cost. Hyundai has released software updates that improve stability. In rare cases where the head unit hardware fails, replacement costs 300-400 euros. This is a quality-of-life annoyance rather than a safety concern.
One of the simplest and lowest-risk crossovers available
The Bayon 1.2 MPI benefits from an extremely simple powertrain: naturally aspirated, port-injected, chain-driven, no turbo, no GPF, no mild hybrid system, and manual gearbox only. This eliminates the turbo, DCT, GPF, and 48V issues that affect the 1.0 T-GDI version. The G4LA engine is proven across millions of Hyundai and Kia small cars with no catastrophic failure patterns documented. The main concerns are premature front brake wear (cheap to fix) and occasional ADAS sensor glitches. With regular servicing and Hyundai's 5-year warranty providing good coverage, this is among the lowest-risk small crossovers on the used market.
Recalls and Technical Service Bulletins
Fuel pump impeller swelling causing potential engine stalling (April 2021 - December 2022 production, recall 51DT07)
Verify completed
Contact a Hyundai dealer with the VIN to verify the fuel pump recall (51DT07) has been completed. This recall affects Bayons produced between April 2021 and December 2022, covering approximately 181,000 vehicles worldwide. The repair involves replacing the fuel pump and is free of charge. Note: the DCT recall (41DT05) does not apply to the 1.2 MPI as it is only available with a manual gearbox.
Warranty Status
Factory warranty (5 years / unlimited km)
Check remaining coverage with VIN
Rust perforation warranty (12 years)
Active on all Bayon models
Roadside assistance (5 years)
Included from first registration
Hyundai's 5-year unlimited mileage warranty is one of the longest in the segment and a major advantage for used buyers. Early 2021 models will be reaching warranty expiry in 2026, while 2022-2023 models have several years of coverage remaining. The warranty transfers to subsequent owners within the coverage period. Verify the exact expiry date with Hyundai using the VIN.
