If the Roewe RX5 has no power, you can use the jump-start method to charge it. The specific steps are as follows: 1. Before connecting the jumper cables to the power-supplying vehicle, make sure to turn off the engine first. 2. After connecting the jumper cables to the power-supplying vehicle, be careful not to let the positive and negative terminals of the jumper cables come into contact, as a short circuit can be very dangerous. 3. When removing the jumper cables, disconnect the negative terminal first, then the positive terminal. The reasons for a car having no power are as follows: 1. The car's alternator is malfunctioning. 2. Electrical circuit issues, body wiring harness grounding, or unauthorized modifications to the wiring causing excessive current that burns out the wires. 3. If the entire car loses power when the engine is not running, it may be due to loose or corroded battery terminals or a blown main car fuse.

Last year when I was repairing a car, I encountered a Roewe RX5 that was completely dead. The owner said there was no response when inserting the key. In this situation, the first step is to confirm the battery status to see if the battery is old or dead. Use a voltmeter to measure the battery voltage—if it's below 12 volts, you'll need to charge or replace it. If it's not a battery issue, then check the 15-amp starter fuse in the main fuse box, as many cars experience a complete power loss due to this fuse blowing. Next, inspect the wiring connection of the ignition switch, especially the connector at the base of the steering column, which is prone to loosening. Also, verify whether the anti-theft system was accidentally triggered—try using the spare key near the start button. If the cause still can't be found, it's best to visit a 4S shop for professional diagnostic tool testing rather than tampering with the wiring yourself.

Last month, my neighbor's Roewe RX5 suddenly had a complete power failure, and I took a look at it for him. First, I tried unlocking it with the remote key, but there was no response, which basically ruled out the issue with the remote battery. Upon opening the hood, I found the battery terminals covered in white crystals. After rinsing the terminals with hot water and tightening the connections, there was still no power. Later, I opened the driver's side fuse box and discovered a 30-amp fuse labeled 'IGN' that was burnt black. Replacing it with a spare fuse immediately fixed the problem. Such issues are often caused by the smallest fuses, so it's advisable to keep a fuse kit for your specific car model in the trunk. If you're not comfortable replacing fuses yourself, it's best to call a tow truck and take it to a repair shop.

A complete loss of power in the vehicle is usually related to the power supply system. First, open the engine compartment and check if the battery terminals are loose or corroded. Clean them and tighten them to see if that helps. Next, open the fuse box in the driver's seat and locate the main relay and main fuse to see if they are blown. If these are all normal, the key sensing module may be faulty. Try using another key near the ignition switch. It could also be that the body control module has crashed. Disconnect the negative terminal of the battery for five minutes to reset the system. If these simple methods don't work, it's likely time to send the car for repairs.

I've dealt with several RX5 models that had no power, and my experience suggests a three-step troubleshooting process. First, check the power supply side: measure the battery voltage, clean the terminal posts, and inspect the alternator output wires. Next, examine the transmission side: check the fuses and relays related to starting in the fuse box, and determine the status of low-current power supply by seeing if the cigarette lighter in the center console has power. Finally, inspect the control side: pay attention to whether there's a faint flicker on the instrument panel when pressing the start button—if there is, it indicates the circuit is intact but the control module is faulty. Throughout the process, remember to disconnect the battery before performing any operations to prevent the risk of short circuits.
