MG HS AS23 — Problems & Common Faults

Weaknesses, engine ratings and buying advice

★★★★★

Everyday hassle beyond the engine: low from 6 vehicle weaknesses (electrics, body, interior, suspension)

The MG HS launched on the German market in 2021, offering an unusually generous price-to-equipment ratio as a compact SUV: lots of kit, a decent interior and a punchy 1.5-litre turbo petrol engine with 162 hp, available with a manual or a 7-speed dual-clutch automatic. From the start there was also the EHS plug-in hybrid with 284 hp system output and a 16.6 kWh battery for around 50 kilometres of electric range. A facelift arrived in late 2023 with a revised front end and infotainment, sold alongside the second generation until mid-2024.

For a used buy, the dual-clutch gearbox deserves close attention: several independent sources describe hesitant, jerky shifting at low speed and on hills - a test drive in city traffic will reveal the issue reliably. The infotainment system is also a known weak point: the touchscreen often reacts sluggishly, and dropouts of the radio or hands-free function have led to workshop visits lasting weeks. The driver-assistance systems - traffic-sign recognition and attention monitoring - stand out negatively for false alarms and misread speed limits.

The EHS plug-in hybrid brings its own model-specific issues: AC charging is modest at single-phase 3.7 kW maximum, so a full charge takes a while. In winter the petrol engine frequently kicks in for heating, even with a full battery, which drags real-world electric range down to 30-45 kilometres. In isolated cases a complete hybrid-system failure with limp-home mode has even been documented - rare, but with a long repair time. Important for buyers of early EHS cars (built 2021/2022): a KBA recall covers a potentially loose grounding cable on the heater element with a fire risk, so the recall status should definitely be checked against the VIN before buying.

Other, rarer issues include water ingress from clogged panoramic-roof drains (one case cost around €2,500 out of warranty), peeling paint on the alloy wheels, and isolated early corrosion on brakes and exhaust. Structural engine problems such as timing-chain or turbocharger failures are not yet backed by independent sources for the 1.5-litre turbo - though for an engine that is still relatively young and not very common in Germany, that may simply reflect a lack of long-term experience rather than genuine robustness. The UK's What Car? reliability survey rates the petrol HS at 87.9%, below average, while the PHEV scores 92.5%, close to the family-SUV average.

For a used purchase: take a city-traffic test drive paying attention to gearbox behaviour, test every infotainment function, check recall status and charging behaviour on EHS models, and look for dampness in the footwell on panoramic-roof cars. Anyone after affordable everyday comfort who can live with the noted weaknesses gets a lot of SUV for the money.

Engine Overview

The MG HS AS23 is available with 2 engine variants — from 162 to 284 hp.

1.5L Turbo GDI · Petrol· 162 PS
2021 2024

The turbocharged 1.5-litre four-cylinder with direct injection is a comparatively young design from SAIC Motor with little long-term track record on the European market. Structural long-term weaknesses such as timing-chain or turbocharger failures are not yet backed by independent sources. What stands out is the relatively high fuel consumption for its displacement class recorded in testing, which also showed up negatively in the Green NCAP environmental rating. Buyers considering a used example should insist on a complete service record, since reliable data beyond 150,000 kilometres is still missing.

No known weaknesses documented.

Vehicle Weaknesses

WeaknessCost
✖Recall: grounding cable on heater element (fire risk)

On early EHS plug-in hybrid models, an incorrectly routed grounding cable on the electric heater element can loosen and overheat. The German KBA recall warns of a fire risk in the footwell.

Low
✖Hybrid drivetrain failure with limp-home mode

In isolated EHS cases a complete hybrid system failure was documented: the car drops into limp-home mode or stops altogether, and the gear selector can no longer be moved out of position P. One documented case took around 16 months to be repaired.

Symptoms: Warning message in the instrument cluster, car can no longer be moved out of the park position, significant power loss in limp-home mode.
