MG HS 1.5T Mk1

The 7-speed DCT fitted to automatic MG HS models exhibits jerky gear changes at low speeds, particularly when pulling away or creeping in traffic. This is partly a calibration issue (improved with software updates) and partly inherent to dry-clutch DCT design. Some owners find improvement by switching to AMT mode in the engineering menu. In more severe cases, the clutch pack wears prematurely, especially in city driving with frequent stop-start. A software recalibration costs around €200-500, while a clutch pack replacement runs €1,500-3,000 depending on whether an independent specialist or MG dealer performs the work. DCT fluid changes every 60,000 km help prolong clutch life. Manual gearbox models are not affected.

This is the most frequently reported complaint among MG HS owners. The 10.1-inch touchscreen can freeze, go completely blank, or reboot unexpectedly. Since the screen controls climate, navigation, and most vehicle functions, a frozen screen is more than just an inconvenience. In many cases a battery disconnect reset resolves the issue temporarily. MG has released software updates that help, though some units continue to malfunction. If the head unit needs replacement, it must be sent to MG UK for reprogramming, which takes approximately 7 days with the car off the road. Head unit replacement costs approximately €500-1,000 at dealer. Most cases are covered under the 7-year warranty.

Multiple owners report the 12V battery going flat after just a few days of the car sitting unused. Parasitic draw measurements show 70-150 mA or more with everything supposedly off, well above the acceptable 50 mA threshold. The infotainment system and T-box (telematics module) appear to be the main culprits. A higher-capacity AGM battery replacement costs €150-250 and helps in mild cases. In some instances the alternator needs replacing (approximately €350-400 fitted). MG has acknowledged this issue on certain production batches and a dealer software update can reduce the parasitic draw.

Owners report intermittent warning lights for TPMS, ABS, ESC, and the ADAS driver assistance systems that appear briefly and then clear themselves. The lane departure and forward collision warnings can trigger in clear conditions on straight roads. These are mostly software calibration issues rather than actual sensor failures. A sensor recalibration at the dealer costs €100-250. In rare cases a faulty wheel speed sensor or TPMS sensor needs replacement at €150-300 per unit. The issue is annoying rather than dangerous but erodes confidence in the vehicle's systems.

Build quality is below European and Korean standards. Interior creaks and rattles from the dashboard, door cards, and rear cargo area develop within the first 12-18 months. The doors sound slightly tinny when closing. While cosmetic rather than mechanical, these issues contribute to an impression of low quality. Dealers can sometimes fix rattles by adding foam dampening material or tightening clips, typically at no cost under warranty. Out of warranty, an independent trim specialist can address specific rattles for €100-300.

On models equipped with the panoramic sunroof, the drain tubes can become blocked with debris, causing water to accumulate and leak into the cabin via the A-pillars or into the glove compartment. Symptoms include a damp smell, foggy windows, and wet carpet in the front passenger footwell. MG states that clearing the drains is the owner's responsibility as per the manual. Clearing the drains is a simple task (compressed air or flexible wire) costing €0-50 if done yourself. If water damage has occurred to carpet, wiring, or electronics, repair costs can reach €300-600. Models without the panoramic sunroof are not affected.
