Why can't the Roewe RX3 start?
4 Answers
Roewe RX3 may fail to start due to a dead battery or spark plug failure. On November 15, 2017, SAIC Roewe officially launched its new compact SUV, the RX3. The vehicle is equipped with 1.6L/1.3T engines and offers a total of 7 models. Here are the correct methods for maintaining your car battery: Regular battery cleaning: Pay attention to the battery's condition during daily use. Over time, the battery may become covered with dust, powder, grease, etc. To ensure normal operation, promptly clean dirt from the battery panel and terminals to extend its lifespan. Avoid prolonged parking: If the vehicle remains unused for an extended period, the battery will self-discharge. Therefore, even if the car is not in regular use, it is recommended to start it once a week and take it for a short drive to keep the battery fully charged. Regular inspection: The typical lifespan of a car battery is 3-4 years. For high-end models with more electronic systems, the battery's lifespan may be shorter. Regular checks of the battery's charge level can help maintain it in optimal working condition.
I've been driving for over a decade, and this kind of failure to start is most commonly caused by battery issues. It happens most frequently on winter mornings when the dashboard lights are dim, and turning the key only produces a clicking sound. It could be due to an aging battery that can't hold a charge, or you might have left the headlights on after parking, causing the battery to drain. A jump starter is an essential tool to keep on hand for emergencies. If the battery frequently drains, you should also check if the alternator belt is loose or if the battery terminals are corroded. If the battery is over three years old, it's bound to need replacement sooner or later—otherwise, it might suddenly fail when you least expect it. Nowadays, new batteries come with fast-charging technology, allowing the car to start in just 15 minutes even when the battery is low.
Last week I helped a neighbor with this issue - the starter just clicks but doesn't turn over when trying to start. It's most likely the starter gear getting stuck. These old-style starters wear out their carbon brushes over time, and when voltage drops they can't turn the flywheel. Or it could be the starter relay (that little black box) short-circuiting from water ingress - just replace it for about 30 yuan. Some cars may have a failed crankshaft position sensor, causing the ECU to not inject fuel or spark at all. I remember one time after car washing it wouldn't start - turned out water got into the engine bay and shorted a 15A fuse for the starting system (clearly marked on the fuse box cover). Repair shops using diagnostic tools to read trouble codes give the most accurate diagnosis - don't go taking things apart randomly yourself.
Fuel system issues are particularly easy to overlook. Last time, right after leaving the gas station, the car wouldn't start—it turned out to be low-quality gasoline with so much water content that it clogged the fuel injectors. Or if you don't hear the fuel pump humming, opening the fuel tank cap makes it clearest. Not changing the fuel filter for two years can also cause insufficient fuel supply; this part is located near the right rear wheel. When the anti-theft system locks the engine, a small car icon flashes on the dashboard—just pull out the key, wait ten minutes, and reinsert it. A dead key battery is the most frustrating; everything seems normal except the car won't start, and replacing the coin cell solves it.
