Radio and Electrical System Malfunction

Problem: A number of BYD Atto 3 drivers have encountered an issue where the radio turns on by itself after parking and switching off the vehicle. It has been speculated this could linked to the 12V battery, especially if the main traction battery's charge is diminished. There have been reports of the radio spontaneously turning on after the car is parked and turned off. This issue has shown a tendency to worsen over time. A connection with the 12V battery is suspected, which drains quickly, especially if the traction battery's charge is low.

Solution: The BYD service team should be contacted for a thorough check, as the 12V battery issue might be part of a larger electrical system anomaly.

Windshield Fogging Issue

Problem: Owners have noticed severe fogging of the windows when the car is locked normally. Some have pointed to an HVAC system issue, requiring an unusual lock/unlock sequence to clear the windows.

Solution: This appears to have been resolved with an OTA to v1.6 A of the car's software. If this issue persists consult with BYD's customer support can offer insights into any updates or recalls that address the HVAC configuration problem.

Power Failure Issue

Problem: There are instances of power failure where the car becomes unresponsive with no prior warning. The starter battery displays a very low voltage which may require recharge and the addition of a Bluetooth battery monitor.

Solution: BYD's support and warranty services should assist with these power issues, especially concerning battery health, which is a crucial component of an EV’s reliability.

Sunshade Trouble

Problem: Some users have experienced the sunshade getting stuck in the open position, impervious to menu option adjustments or initialization attempts.

Solution: This mechanical issue may require physical inspection and potential replacement by a qualified BYD technician.

SIM Card Connectivity

Problem: A lack of data activation and missing ICCID number on the DiLink system suggest problems with the SIM card or reader, leading to customer care frustrations.

Solution: Persistence in coordination with customer service is necessary. A replacement or technician visit might be needed to troubleshoot the SIM-related concerns.

Apple CarPlay Malfunctions

Problem: Users also report issues like the absence of turn-by-turn voice navigation via Apple Map due to suspected software glitches.

Solution: Keeping all software and applications updated might resolve some issues, but ongoing bugs should be reported to BYD or checked at the dealership.

12V Battery Issue

Problem: There are reports of the 12V battery frequently discharging completely, temporary fixes like trickle charging provide only short-term relief.

Solution: BYD should be contacted for support on this recurring problem, which may include a permanent fix or replacement advice.

Rust Issue

Problem: Rust has been discovered on certain parts of damaged Atto 3 vehicles. However, the issue seems isolated to vehicles that have been through severe accidents and sold at auction as statutory write-offs.

Solution: Despite being an isolated issue, regular maintenance checks and inspections for rust can identify and eliminate early signs of rust.

Charging Issues and Response Time

Problem: An error message 'Check OBC System' has impeded charging attempts, with slow response times from BYD reportedly adding to the problem.

Solution: Persistent follow-up with customer service is key to expedite investigation and resolution.
