✅ 2025 Overview: Versions, Strengths, and Limitations
In 2025, the BYD Tang is a 7-seater SUV available in a 100% electric (EV) configuration and, in some markets, a plug-in hybrid (DM-i PHEV) . It is powered by the BYD Blade Battery (LFP) platform, features a spacious interior, and is fully equipped with ADAS.
- Strengths: 7-seater habitability, LFP battery safety, equipment, price/content ratio.
- Typical limitations (from real-world feedback): high weight → brake/tire wear; infotainment/ADAS software bugs ; rapid charging curve variability; noise from trim on rough surfaces.

🔧 BYD Tang Main Issues (2025 Update)
Collection of the most reported critical issues on the BYD Tang EV/PHEV: 12V battery , software/infotainment , AC/DC charging , brakes and suspension , air conditioning/heat pump , ADAS and sensors , finishes/noise .
1) 12V battery and energy management: “dead car”, random errors
- Typical symptoms: car that won't "wake up", multiple error messages, unavailability of systems (climate, infotainment, ADAS).
- Common causes: 12V battery weakened by prolonged stops/cold, sleep systems that do not recharge correctly, abnormal module absorption.
- Quick fixes: 12V battery test, smart battery maintainer if the car is stationary, BMS software update, DC-DC control. If replacing, use the correct specification (AGM/EFB or equivalent provided by BYD) and follow the post-installation reset procedure .

- Symptoms: Screen freezing , random reboots, lost user profiles, apps not connecting to the car.
- Causes: Outdated firmware, full memory, conflicting apps, weak modem/antenna signal.
- Solutions: OTA update (or workshop update), factory reset (backup preferences first), certified smartphone data cables, check unit ground/power connections.
3) AC/DC Charging: Fluctuating Curves, Sensitive Ports, Cables
- Symptoms: Charging times take longer than expected, sessions that drop out, difficulties with some fast chargers, port that won't unlock.
- Causes: non-optimal battery temperature, charging management firmware, handshake with particular columns, non-compliant or worn Type 2 cable .
- Solutions: Precondition the battery when available, try another charging station/operator, use a good-quality 32A certified Type 2 cable , check the door lock and actuator; OBC/DC-FC updates if applicable.

- Symptoms: noisy brakes after rain/parking, vibrations during prolonged braking, “dry” ride on potholes, uneven tyre wear (heavy weight).
- Causes: prevalent use of regeneration → less disc cleanliness, vehicle mass on arms/bushings, non-uniform wheel tightening torques.
- Solutions: Regular "cleaning" of the brakes to keep the discs shiny, check the bushing/rod clearance, check the alignment and tire pressure (loads/7 seats). If vibrations occur: resurface or replace the discs/pads, clean the caliper supports.
5) Air conditioning/heat pump: low performance in cold weather, odors in cold weather
- Symptoms: Interior takes a long time to warm up/cool down, initial odor, persistent fogging.
- Causes: conservative heat pump logic, saturated cabin filter, condensation in the exchanger, humidity/temperature sensors out of range.
- Solutions: HVAC software update, premium cabin filter (carbon/HEPA where applicable), air circuit sanitization, sensor and duct check; use pre-air conditioning while charging.
6) ADAS/sensors: false alarms, misalignments, calibrations
- Symptoms: Overly sensitive collision/lane keeping warnings, continuous beeps in rain/fog, “nervous” adaptive cruise control.
- Causes: camera/radar to be recalibrated after work on the windshield/trim, dirty sensors, outdated firmware.
- Solutions: ADAS calibration with official template after glass/suspension, cleaning sensors and front mask, updating control units.

7) Interior finishes: creaks, vibrations, door panels
- Symptoms: Noises on uneven surfaces, plastic vibrations, panels that “play”.
- Causes: Clips/fixing points with tolerances, thermal expansion, cable glands touching.
- Solutions: application of anti-friction felt/foam, tightening torque check, panel realignment in the workshop.

❓ Frequently Asked Questions
Is the BYD Tang 2025 reliable?
Overall, yes, but like many new-generation EVs, it may require periodic software updates and attention to the brakes/suspension due to its weight. Timely maintenance and OTA reduce the risks.
Why is fast charging sometimes slower than advertised?
It depends on battery temperature, state of charge (SOC), charging station, and firmware. Use preconditioning when available and aim for 10–60% charging to maximize power.
Noisy brakes after rain: is it normal?
Yes, on many EVs, the discs tend to rust due to poor braking. Perform "clean" braking and consider having the calipers/discs cleaned at a workshop if the problem persists.
BYD app: doesn't always connect to the car
Check data coverage, update apps and car firmware, and re-pair your account/vehicle. If the problem persists, perform a factory reset (after backing up).
🏁 Conclusions
The BYD Tang 2025 is a fully-featured 7-seater electric SUV/PHEV. Understanding recurring issues (12V, software, charging, braking/suspension) and addressing them preventatively with updates, targeted maintenance, and suitable spare parts helps keep costs down and extend the vehicle's life.
