Reason for failure of Geely gx7 back door automatic lock: 1, poor line contact of central control system; 2, the car lock is rusty; 3. The motor lock position of the door lock moves; 4. The door lock motor is broken and the tension is not enough; 5. The remote control lock is invalid or the antenna of the remote control transmitter on the vehicle is aging; 6. There is strong magnetic signal interference around the car. Geely GX7 draws lessons from the chassis of RAV4, so the overall structure is almost the same. GX7 front subframe adopts "composite" full frame structure, which is optimized on the basis of ingot beam. The left and right longitudinal beams of the subframe are detachably connected, and the axle shaft is obviously corroded. Although the semi-axle is not seriously rusted, it will not affect the quality of the whole vehicle, but such details are enough to show that the manufacturer is not strict with the quality control of suppliers. The longitudinal beam of Geely GX7 chassis has a high degree of shape recognition, and the transverse reinforcement attached to the eight-shaped longitudinal beam can improve the torsional capacity of the chassis and have a positive impact on power transmission. The thickness and area of the anti-corrosion coating on the chassis are comprehensive, covering more than 95% of the chassis area. The oil tank is made of resin, and the oil pipe of the chassis is embedded in the longitudinal beam, so it is not easy to damage the oil pipe when the vehicle supports the bottom. Non-metallic fender cover under carbon canister. The only disadvantage is that the coverage of the chassis insulation layer is small.
