Is It Advisable to Purchase a 2019 Stock Vehicle?

Stock vehicles can be purchased, but the following conditions must be met: First, the discount must be substantial enough; second, the condition of the stock vehicle must be good. Although manufacturers do not neglect stock vehicles and perform a certain degree of maintenance, it is still difficult to guarantee that internal plastic components won't deteriorate. Additionally, you can request the 4S dealership to replace the engine oil, oil filter, and other components. For vehicles stored for an extended period, you may also ask for a battery replacement. The differences between a stock vehicle and a new car are as follows: 1. After leaving the factory, various fluids, electronic components, the battery, rubber seals, and tires in a new car may suffer from moisture damage and aging if left idle for a long time without periodic inspection and maintenance. 2. Only a very few dealers perform periodic inspection and maintenance measures, which are not costly but require manpower and time. Some 4S dealerships even store vehicles in open-air lots, exposing new cars directly to sun, rain, and wind. 3. For stock vehicles stored for too long, without proper warehousing management, the aging of electronic components and rubber products often goes undetected without professional testing equipment. Many vehicles stored for too long also experience issues like oil and power shortages.

Should I Go to the Vehicle Management Office or Inspection Station for Vehicle Inspection?

Vehicle inspection requires visits to both the Vehicle Management Office and the inspection station. The Vehicle Management Office primarily handles applications for motor vehicle driver's licenses, replacements, renewals, inspections, and other related services for vehicles and drivers. On the other hand, the inspection station focuses on comprehensive performance testing of motor vehicles. While the two are related, their functions are distinctly different. More relevant information is as follows: 1. For vehicles requiring on-site inspection, both the Vehicle Management Office and inspection station must be visited: After the six-year exemption period or for vehicles requiring on-site inspection, the normal procedure is to first complete the inspection at the station and then proceed to the Vehicle Management Office for stamping. However, in some areas where the inspection station and Vehicle Management Office are networked, the entire inspection process may be completed directly at the inspection station. 2. Vehicles applying for exemption from inspection must meet the following conditions: 1) Motor vehicles registered within 6 years: Non-commercial cars (including large cars) and other small and mini passenger vehicles. 2) Excluding minivans: Vehicles with 7 or more seats. 3) Vehicles not registered for over 4 years: Excluding vehicles that have not been registered for over 4 years since their manufacture date. 4) Vehicles involved in no injury-causing traffic accidents: And have no pending traffic violation records.

What causes the key symbol to flash on the Sylphy display screen?

When the key light flashes on the dashboard, possible reasons include the vehicle not detecting the smart key, low battery in the key, etc. Electromagnetic shielding can also affect the signal transmission of the key. The flashing key icon on the dashboard is the anti-theft system indicator, indicating that the anti-theft system is activated. When this light is on, the car cannot be started, and repeated ignition attempts may lock the engine, also known as engine immobilization. The anti-theft indicator has armed and disarmed states, with different flashing frequencies for each state. The indicator will flash in a regular pattern, and the flashing frequency will also vary when unlocking and driving. Methods to resolve the flashing key light: Check if the key is inside the car or nearby; replace the key battery—the Sylphy key uses a CR2025 battery, which must be replaced according to the model; take the vehicle to a professional repair shop or 4S store for a detailed inspection of the key signal transmitter and receiver. Common dashboard indicators while driving: Engine malfunction light: If the engine malfunction light comes on, it indicates a fault in the engine system, and you should contact a 4S store or repair shop immediately for maintenance. Coolant temperature warning light: If this light appears, it means the vehicle's coolant temperature is too high, possibly due to insufficient coolant. You should stop and check the situation. If the temperature is too high, do not continue driving. Tire pressure indicator: If the tire pressure light comes on, it may indicate that the tire pressure is too high or too low, possibly due to a leak or over-inflation. Use a tire pressure gauge to check the current pressure. Brake system warning light: If the brake system warning light comes on, it indicates a fault in the vehicle's braking system, which could be due to mechanical failure or insufficient brake fluid. You should stop and inspect the situation. Fuel indicator: If this light comes on, it means the vehicle is low on fuel, and you should find the nearest gas station to refuel.
