Perusing problems reported to agencies , not all inclusive (Dolphins have been in certain dry, salt free regions about a year)
Many of the common logged complaints are pretty meh
but hidden rust all over, getting blasted with white powder from hvac, OTA updates bricking cars, power loss, charger failures and a constantly dead 12v battery are concerning
Multiple “under hood” fires reported (not battery) are also concerning but I lack the language skills to understand the context.
Then there are the “other” domestic BYDs
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.
- Over the air updates sometimes brick the car requiring a warranty visit
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 initialization 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.
Rust issue non-galvanized contact surfaces, brackets and other fasteners unpainted/ungalvanized areas under car and inside panels that aren’t visible during normal use
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.
Evaporator/Condenser Coorsion / Failure
- Large amounts of White powder would blow out the air vents, testing found it was aluminum oxide & hydroxide and car required HVAC components replaced
Despite all the above real common complaints against BYD they are honestly still doing better than most Chinese vehicles but considering the 1970’s Fiat level of rust prevention I would never own one here.
