For the 2019 Alfa Romeo Stelvio, it is recommended to conduct regular maintenance every 10,000 kilometers or 12 months, whichever comes first. The main items include changing the engine oil and oil filter, and checking the brake system, tires, suspension, and the status of various fluids. In Malaysia's hot and humid climate, it is advisable to pay extra attention to the cabin air filter and the battery health. When the mileage reaches 20,000 kilometers, the air filter needs to be replaced. At 40,000 kilometers, a major maintenance such as changing the transmission fluid and differential fluid is required. As an imported Italian model, the Stelvio is equipped with precision components like an all-aluminum engine. It is recommended to strictly follow the original manufacturer's maintenance specifications and use certified 0W-20 fully synthetic engine oil. Malaysian car owners should also pay attention to regularly cleaning the vehicle's underbody to prevent seawater corrosion. If you often drive in congested areas, you can appropriately shorten the replacement cycle of the brake fluid. The Q4 all - wheel - drive system and the DNA driving mode selector installed in this car need to be calibrated with professional equipment. It is recommended to choose an Alfa Romeo authorized service center for maintenance. They are familiar with the maintenance points of the unique MultiAir solenoid valve technology of this model, which can ensure that the vehicle maintains its best performance.

The 2021 Lexus ES 250 doesn't use a turbocharged engine. Instead, it's equipped with a 2.5 - liter naturally aspirated four - cylinder engine with a maximum output of 203 horsepower, paired with an 8 - speed automatic transmission. This powertrain is well - known for its smoothness and reliability, making it highly suitable for city driving and long - distance trips in Malaysia. The Lexus ES series has always been promoted for its luxury, comfort, and noise - reduction technology. The 2021 ES 250 also has many upgrades in interior materials and technological features. For example, the Lexus Safety System+ comes as standard, which includes functions like pre - collision warning and lane - keeping assist, enhancing driving safety. For Malaysian consumers, although naturally aspirated engines don't have the same explosive power as turbocharged models, their maintenance costs are relatively low. Moreover, the Lexus brand has a well - established after - sales service network locally, making long - term use more worry - free. If you have higher power requirements, you can look into the ES 300h hybrid version, which strikes a better balance between fuel economy and performance.

The battery life of the 2021 Lexus ES 250 usually ranges from 3 to 5 years, depending on usage habits and the climate conditions in Malaysia. Since the local high - temperature and high - humidity environment can accelerate the evaporation of battery electrolyte and electrode corrosion, it is recommended to regularly check the battery status and conduct timely maintenance. If you often drive short distances or let the car stand for a long time, the battery life may be shortened, while maintaining a stable long - distance driving habit helps to extend its service life. In addition, the original Lexus battery is of reliable quality. However, when it comes to replacement, you can also choose third - party brands that meet the specifications, such as well - known products like Varta or Bosch. In daily use, avoid excessive power consumption of in - vehicle electrical appliances when the engine is off, and you can regularly monitor the battery health with a voltage detector. When the vehicle starts significantly slower or the warning light on the dashboard comes on, you should go to an authorized service center for inspection in time. It's worth noting that the battery system of hybrid models is different from that of conventional lead - acid batteries. As a fuel - powered vehicle, the battery replacement cost of the ES 250 is relatively low, usually ranging from 800 to 1500 Malaysian ringgit. The specific price will vary depending on the brand you choose and the repair shop.

Under normal use and regular maintenance in Malaysia, the 2021 Lexus ES 350 can usually travel over 250,000 kilometers or be used for more than 15 years. This longevity is largely attributed to its reliable 3.5-liter V6 engine and the brand's consistent high-quality craftsmanship. As a luxury brand under Toyota, Lexus is known for its durability and low failure rate. Especially in Malaysia's hot and humid climate, its anti - rust treatment and the stability of the electronic system perform excellently. To extend the vehicle's lifespan, it is recommended that owners strictly follow the maintenance manual for upkeep. In particular, regularly change the engine oil, transmission fluid, and coolant. At the same time, pay attention to checking the braking system and suspension components. The road conditions in Malaysia are diverse, with frequent traffic jams and long - distance driving. Therefore, it is recommended to conduct a comprehensive inspection every 50,000 kilometers, including the chassis and transmission system. Lexus has a well - established after - sales service network in Malaysia, and there is an ample supply of original parts, which is also an important factor in ensuring the long - term use of the vehicle. For consumers considering buying a used car, the 2021 ES 350 is a good choice due to its reliability. However, it is essential to check the maintenance records and the vehicle's historical report. Lexus's hybrid versions usually have a longer engine life because the electric motor shares part of the workload. However, the ES 350 currently only offers a gasoline version. In the Malaysian market, Lexus models generally have a relatively high resale value, which also reflects their long - term reliability from the side.

In the Malaysian market, the Premium Package of the 2021 Lexus ES 250 mainly includes a number of luxury configuration upgrades. For example, there's a 12.3 - inch touch - screen display, a Mark Levinson premium audio system, a panoramic sunroof, semi - aniline leather seats, an electrically adjustable steering wheel, and a more advanced intelligent safety system (such as LSS+ 2.0, which includes adaptive cruise control, lane - keeping assist, etc.). These configurations significantly enhance the vehicle's comfort and sense of technology, making it suitable for users who pursue a high - quality driving experience. It's worth noting that as a high - end brand under Toyota, Lexus has always been well - known for its reliability and after - sales service in the Malaysian market. The 2.5 - liter four - cylinder naturally aspirated engine (204 horsepower) equipped in the ES 250 offers a smooth power performance, but it's more suitable for city driving rather than aggressive handling. In addition, Malaysian consumers can compare it with luxury models of the same class from German or Japanese brands when making a purchase. However, Lexus' high resale value and low failure rate are still its prominent advantages. It is recommended to choose the configuration package according to personal budget and needs, and at the same time, pay attention to whether local dealers have promotional activities for this package.
