The MG ZS, a subcompact crossover SUV produced by Chinese automaker SAIC Motor under the British MG make, has gained popularity among drivers across international markets. However, like any other car model, the MG ZS is not without its share of common problems. In this comprehensive guide, we will explore the most frequently reported issues with the MG ZS and provide insights on how to tackle them effectively.
Section 1: Engine Problems
The MG ZS has encountered several engine-related problems, as reported by drivers. These issues can manifest in various ways, including a loss in engine performance, engine noise, and frequent misfires. It is important to address these problems promptly to prevent further damage to the engine.
One common cause of engine power loss and other symptoms is a clogged component within the vehicle, such as the air filter, fuel filter, or catalytic converter. Over time, these components can become blocked with debris, resulting in a decline in engine performance. If you experience any of these symptoms, it is recommended to have a trained specialist inspect your car to identify the exact cause of the problem.
The average cost for an engine repair on the MG ZS is £169.29 when booked through WhoCanFixMyCar, a platform that connects car owners with trusted mechanics.
Section 2: Head Gasket Problems
Head gasket failures have been reported in several MG car models, including the MG ZS. The head gasket plays a crucial role in sealing the combustion chambers and oil passages between the engine’s block and the head. When the head gasket fails, it can lead to various issues such as higher temperatures and depleting coolant levels.
Owners of older MG models, such as the K-series, TF, and GS, have experienced head gasket failures. The K-series MG cars, in particular, had poorly designed gaskets that couldn’t withstand the heat generated by the engine. It is important to have your MG car inspected promptly if you suspect a head gasket failure. Early diagnosis and repair can help prevent costly engine damage.
The average cost for a head gasket repair on the MG ZS is £382.00 when booked through WhoCanFixMyCar.
Section 3: Suspension Problems
The MG ZS has been known to experience suspension issues, particularly with the front suspension system. Drivers have reported hearing noises when driving over bumps in the road, indicating possible wear in the suspension components.
When the suspension fails, the car may feel off balance, and the impact of driving over road surfaces may be more pronounced. It is crucial to have the suspension system checked and repaired by a trained specialist to prevent further damage.
While the exact average repair cost for suspension problems in the MG ZS is not available, repairs for other MG car models on the WhoCanFixMyCar platform have averaged £139.57.
Section 4: Gearbox and Transmission Issues
Both manual and automatic versions of the MG3 model have been prone to gearbox and transmission problems. In the manual version, drivers have reported issues with gears getting stuck, making it difficult to shift smoothly. The automatic version, on the other hand, experiences slow gear changes, especially when shifting into higher gears.
Dealerships and experts have identified the clutch system, synchronizer ring, and hub sleeve as common culprits behind these gearbox issues. Diagnosing and fixing manual transmission problems is generally easier and more affordable. Replacing the synchronizer ring or hub sleeve can effectively resolve gear shifting problems. However, automatic transmission problems are more complex and expensive to repair.
The average cost of replacing a transmission in the MG ZS, including labor and parts, ranges from £1,100 to £3,000.
Section 5: Premature Rusting
Rusting is a common issue in many older cars, and the MG ZS is no exception. Certain models, such as the 2019 MG Hector and MG ZS, have been particularly prone to premature rusting problems.
Rust occurs when cars are exposed to wet weather conditions, leading to corrosion. While some level of rust is expected over time, premature rusting within a few months of purchase is a cause for concern. The MG ZS, equipped with coated Zintec-steel, was designed to prevent rusting for a longer period. However, owners living in wet coastal areas have reported rust spots appearing on their vehicles.
Proper care and maintenance can help prevent rusting for an extended period. Using anti-corrosion products can add an extra layer of protection against the elements. If you notice rust spots on your MG car, it is advisable to contact the dealership to check if the warranty covers rust repair and protection.
Minor rust repairs can cost around £50 to £200, while major repairs may range from £500 to £2,500 for older MG models.
Section 6: ABS Warning Light Issues
The ABS warning light is a crucial indicator on the dashboard that alerts drivers to faults in the antilock braking system. MG ZS owners have reported intermittent ABS warning light issues, with the light sometimes staying on while driving over bumps on the road.
The ABS system is responsible for preventing tire lock-up during abrupt braking, ensuring that the car remains in control and minimizing the risk of accidents. The MG ZS has had a persistent problem with the ABS warning light, often indicating a disabled or malfunctioning ABS system.
Various factors can cause an ABS warning light to illuminate, including a failing wheel speed sensor, a malfunctioning ABS control module, blown fuses, or faulty relays. Diagnosis usually requires the use of a diagnostic tool to scan the system.
A faulty wheel speed sensor is a common cause of an ABS light staying on in MG ZS models. These sensors measure the speed of the wheels and communicate this information to the ABS control unit. Wheel sensors are susceptible to damage due to their proximity to the wheels and the road. Diagnosing speed sensor issues requires specialized tools.
Another potential cause of an ABS warning light is a malfunctioning hydraulic control unit. The hydraulic component of the unit can develop faults that require diagnostic tools to determine the specific problem. ABS hydraulic control units are generally reliable, lasting around 120,000 miles before encountering issues.
Blown fuses or bad relays can also disrupt the ABS system and trigger the warning light on the dashboard. MG ZS owners have reported instances of bad relays and blown fuses affecting various electronics in the car, including the ABS unit. Fortunately, repairing blown fuses and replacing relays is a relatively simple and affordable fix for ABS warning light problems.
Section 7: Oil Leak Problems
Oil leaks are a common issue in both new and old cars, and MG vehicles are not exempt. Detecting oil leaks is relatively straightforward; simply check under the car after it has been parked for a while. The MG3 model and older MG versions have been known to experience oil and coolant leak problems, which can originate from various sources such as gasket covers, pressure hoses, filters, or plugs.
Identifying the location of the oil leak is crucial in determining which components are causing the problem. For example, leaks from the rear of the car may indicate issues with the rear axle and differential, such as leaking pinion oil seals or rear hub seals and gaskets.
Minor oil leaks can typically be fixed quickly and affordably. However, larger problems, such as leaks from the head gasket, may require more expertise and incur higher costs.
Section 8: Reliability and Owner Satisfaction
Despite being the best-selling car model from the Chinese automaker, the MG ZS fares disappointingly in owner satisfaction and reliability. In the 2022 owner satisfaction survey carried out by Car Buyer, MG finished in 28th place out of a total of 29 manufacturers. 35.2% of MG owners reported a fault in their first year of ownership, which contributed to the low rating. The model itself placed 61st out of a total of 75 cars in the survey due to reports of unreliability and poor build quality.
In terms of safety, the MG ZS also failed to match the standard set by its rivals. In the Euro NCAP 2017 crash test, the ZS scored a mediocre three out of five stars overall, with adult and child occupant safety ratings of 71% and 51% respectively.
