BYD ATTO 3 Standard Home Charger

Owning an electric vehicle like the BYD Atto 3 promises a green and efficient ride, but like any other electric car, it isn’t immune to occasional hiccups. In this post, we’ll explore some of the common BYD Atto 3 problems and issues reported by Atto 3 owners and offer insights into potential solutions.

Radio and electrical system malfunction

  • The radio turns on itself after parking the car, even when everything else is turned off.
  • The frequency of occurrence has increased over time.
  • Suspected connection to the 12V battery issue, which drains quickly if the traction battery charge is low.

Severe fogging issue

  • Locking the car normally causes windows to fog up.
  • Fogging can be prevented by performing a specific lock/unlock sequence multiple times an hour.
  • Believed to be an HVAC configuration issue.

Windshield fogging issue

  • Extreme fogging is observed in specific conditions.
  • Inability to run the air conditioning on recirculation mode and heat on maximum to manage moisture absorption.

Power failure issue

  • The car suddenly became unresponsive without any warning or indication of a problem.
  • Discovered the starter battery had a very low voltage reading.
  • Recharged the battery successfully and installed a Bluetooth battery monitor.
  • Highlighted deficiencies in customer care and support, including limitations on battery replacement.

Sunshade issue

  • The sunshade is stuck in the fully open position and unable to close.
  • Attempts to resolve through menu options and initialisation methods have been unsuccessful.

SIM card issue

  • No data activation despite waiting for the specified period.
  • The original DiLink screenshot lacked an ICCID number, indicating a problem with the SIM card or reader.
  • Frustration with customer care’s failure to identify the issue initially.

Apple CarPlay issue

  • Apple Map lacks turn-by-turn voice activation.
  • Attempts to resolve this by adjusting Bluetooth and iPhone volume have been unsuccessful.
  • Suspected a software bug causing the lack of sound.

12V battery issue

  • 12V battery frequently becomes completely discharged, rendering the car inoperable.
  • Temporary revival is achieved through trickle charging, but the battery quickly drains again.
  • Seeking information about the discharge-recharge cycle in EVs and when the 12V battery is topped up from the main battery.

Rubber Tree mats issue

  • Unsatisfactory customer service experience with Rubber Tree regarding feedback on their mats for Atto 3.
  • Requested a full refund due to the length and misleading photos of the mats.
  • Suggests considering Evgogo mats as a better alternative.

Rust issue  & explanation from the dealership

BYD atto 3 rust problem

  • Upon removal of parts of the damaged Atto 3,  there was a gremlin of rust.
  • The dealership explains that the rust issue was found in a car sold at auction as a statutory write-off after a severe accident.

Charging issue and lack of quick response from BYD

  • Error message “Check OBC System” prevents charging attempts.
  • The car has been sent back to BYD for investigation; it took a long time to respond.

Newly Reported Problems

  1. Another annoying voice alert, “For your safety, please turn off your high beam” whenever turning in a roundabout. BYD expert suggests turning on the ‘Auto headlight’ to fix the issue, but doing so turns on the headlights every time the car is parked in the garage.
  2. The GPS seems to keep rerouting every time and providing the wrong direction. Using AirPlay or Google Maps seems to overcome this issue but has no step-by-step voice assistance and it consumes phone data.
  3. When receiving phone calls, the volume seems to be set by the phone. Had the phone volume set to full and suddenly got a call through and my voice thundered through the speakers.
  4. ACC color on the driver’s display cannot be seen, making it very difficult to know if the ACC is engaged, the same applies to the speed set color. The contrast between the two colors is minimal, especially in high ambient light conditions.
  5. The washer/wiper on the rear window of my Atto 3 sprays water and wipes for no reason at all, often emptying the washer bottle. It will do this up to 8 times per day, particularly on hot and dry days.
  6. EV power limited is coming on the dashboard. Given to the dealer, probably need to change the battery. Only been one year.
