10 Reasons Why BYD Atto 3 Won’t Start

The chances are high that somehow low battery charge, faulty wiring, clogged fuel filter, blown fuse, empty gas tank, dead key fob battery, overheated battery or engine, damaged battery, etc might be potential reasons behind such an issue. But there is nothing to worry about it. Luckily, we’ve managed to share you with a couple of workarounds that should come in handy. Now, without wasting any more time, let’s jump into it.

1. Battery Overcharging

One of the first reasons can be battery overcharging or a poor charging habit which can easily damage the EV’s battery without any second thought. The first reason may be related to the battery overcharging or a poor charging habit. Most users do not care about overcharging or how frequently they charge the battery in a day unnecessarily. In that case, the battery draining might be increases or the battery lifespan will be reduced drastically.

It’ll definitely affect the EV starting scenarios a lot. Obviously, overcharging the EV’s battery might damage the chemical due to excessive heat. You should maintain a time schedule to charge your EV daily or at least try charging it once the battery level drops to 20%-30%. If the battery level is more than 50% then avoid charging on the same day or frequently for a long time. Meanwhile, if you’ve battery range anxiety then make sure to get it checked by a professional technician or visit the manufacturer’s service center.

2. EV’s Battery or Inverter is Overheated

Sometimes the overheating issue can be a major reason behind the EV’s battery or inverter not running. Mostly the inverter unit may get overheated due to the consistent use of EVs on a daily basis. Both the converter and inverter units do generate plenty of heat which can easily impact the battery level and the engine’s performance. Though EVs do have a dedicated ventilation system, it might require some time to transfer heat by turning off the EV or parking it in a cool place.

The C/I unit or Inverter is quite necessary for an EV due to the supply of electricity to the electric motor. Now, if the C/I unit or Inverter unit isn’t running well or gets overheated, your EV won’t start properly or may get power off after detecting overheat.

3. Check the Battery Life Cycle

It’s also possible that the battery life cycle is completed after using the EV thoroughly on a single charge. Sometimes the battery status may show sufficient charge but it can suddenly start showing that the battery level is too low. Now, this kind of situation can leave you in splits especially if you’re driving miles away or driving at midnight. It’s also worth mentioning that even though EVs do have certified battery capacity for the better driving range, that might not be applicable for highways or normal roads.

The chances are high that either the battery life cycle is completed or the software is conflicting somehow. If in case, your BYD ATTO 3 EV is newly purchased and you haven’t driven it that much, it may be a factory defect unit as well. Try contacting manufacturer support or directly visiting the service center to get it checked professionally. Though the complete battery life cycle gets completed after a few years of usage, sometimes the battery health may get reduced drastically.

4. Factory Faults on your EV

As mentioned in the above step, sometimes your electric vehicle may have some factory defects which can be delivered to you by mistake or due to mismanagement with quality checks. Now, it’s quite expected that you won’t notice the vehicle performance or battery-related issues on the very first day after purchase. If you drive your EV on a daily basis then you may notice weird or unexpected things within a couple of days or so. Once noticed, we’ll recommend you visit the service center asap.

Every EV brand does offer a manufacturing warranty and free service facilities to its users across the globe. So, there shouldn’t be any major issue with that. Whatever is required, the brand support will do the necessary steps regarding the repair or replacement procedure. Sometimes a minor defect or hardware-related faults can also trigger the EV not to start issue which can be fixed within a couple of hours by the technician.

5. Road Salt is Troubling your EV

BYD ATTO 3 SUV model does have a subtle sedan design as compared to other EVs. You might not be able to see any major issues with the traction motor, converter, controller, batteries, charger, gear reducer/transmission, cooling system, etc. But that doesn’t mean there is no issue with the car. Sometimes water logging or road salt corrosion can become a major issue behind it.

Basically, EV engine motors are placed near the wheels which indicates some salty elements may easily get contacted and can damage. Due to the moisture and salty corrosion, your EV might get damaged internally or leads to short circuits as well.

6. Dead Key Fob’s Battery

Another thing you can check is whether the key fob’s battery is damaged or not. There are some EVs that can get started without using a key fob. Whereas the keyless car or unlocking the car using a smartphone app can also be a better solution in some cases. But if your BYD Atto 3’s key fob isn’t working to unlock the car or even start the engine then the chances are high that the key fob’s battery is expired.

You should replace the key fob’s battery to start using it again. If in case, replacing the key fob’s battery, didn’t help you out, make sure to get it checked at your nearest official service center.

7. Your EV Requires a Restart

Just like other electric devices, your EV may also require a quick restart which can eventually fix multiple glitches in no time. It’s always recommended to reboot the electric car before heading to the service center or manufacturer support. Just restart the EV and then wait for around a couple of minutes before using it. As always, if restarting your electric car didn’t help to fix the BYD ATTO 3 Won’t Start issue then you can follow the next method.

8. Charging Port Issue

The charging port issue may also be one of the 10 reasons behind the BYD ATTO 3 Won’t Start issue. If you’re living in a colder place and you haven’t charged the BYD ATTO 3 EV for a couple of days or more then it’s quite possible that the EV’s charging port switch is frozen. In that case, you can try keeping it under a high-voltage light or use a hair dryer to slightly heat up the charging port switch.

By doing so, you should be able to use the charging port again to keep charging the battery. While sometimes the battery charging cable can get stuck to the charging port unexpectedly. In that scenario, you should manually try unlocking it using the manual cable from the trunk. Please note that you’ll have to unplug the charging cable from the port and power source before performing it to avoid electrocution issues.

9. Issues with your EV Software

BYD ATTO 3’s software seems good enough as of now apart from minor glitches or bugs. But talking about the software updates, we’re not sure whether the software update is consistent enough or not. It’s better to always keep checking the software updates manually and install them whenever available. A new software update not only brings new features or improvements but also includes bug fixes and other enhancements too. For updating issues, you can contact BYD support.

10. Dead High-Voltage Battery

If none of the methods come in handy, then try checking the battery whether it’s dead or not. Sometimes, your BYD ATTO 3 EV might not start the engine due to the dead high-voltage battery issue. If the EV’s battery produces more than 200 volts then there can be a possible risk of electrocution. So, we’ll recommend you get your electric vehicle checked by a professional mechanic.
