Audi SQ6 e-tron J3
Weaknesses, engine ratings and buying advice
Engine Overview
The Audi SQ6 e-tron J3 is available with one engine variant at 204 hp.
PPE platform dual-motor in the Q6 e-tron quattro and SQ6 e-tron. Two PSM motors (front and rear axle). 800V charging system. SQ6 variant with 360 kW sports tune.
- !! PPE platform software: many faults at delivery from 1,000 km
Q6 e-tron vehicles were delivered with numerous software bugs: missing CarPlay connection, no sound, doors not opening, wrong language setting, Plug & Charge certificate not recognised. Update KD2 (Nov. 2025) resolved many bugs.
Symptoms: CarPlay does not connect, door lock does not open via app, security system warning without reason, warnings in wrong language. Reboot temporarily resolves symptoms. - !! Electric motor vibration — harmonic resonance noise from 10,000 km
Several Q6 owners report harmonic resonance noises from the front area from around 50–60 km/h. Audi plans balance weights for the electric motors in H2 2025/2026 as a solution. Dealers initially classify the noise as normal.
Symptoms: Harmonic humming or droning from the front at 50–60 km/h, independent of tyre brand. Gets louder at higher speeds. - !! 12V electrical system — deep discharge during standstill
Early owners of PPE platform vehicles also report 12V issues. The vehicle requires regular use; extended standing periods without a charge connection can drain the 12V battery.
Symptoms: Vehicle not ready to start after several days of standing. All systems unresponsive. Jump start or workshop visit needed.

Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Driver assistance systems trigger falsely Owners report falsely triggering driver assistance systems: autonomous emergency braking without any obstacle, excessively aggressive lane-keep assist. Software campaigns (06XM, 06XL) are intended to resolve the issue. Symptoms: Autonomous emergency braking with no visible obstacle, uncontrolled steering input from lane-keep assist | Low | |
| Driver assistance systems trigger incorrectly Identical to the Q6 e-tron: autonomous emergency braking without a visible obstacle, overly aggressive lane-keeping assistant. Software campaigns are ongoing. Particularly frustrating in the SQ6 as a performance variant when the assistance system intervenes. Symptoms: Automatic emergency braking without cause, uncontrolled steering input from lane-keeping assistant | Low | |
| Infotainment audio failure after software update After software campaigns some Q6 e-tron units lose all audio functionality: radio, streaming and other sources no longer work. Known issue following over-the-air or workshop updates. Symptoms: No sound from the speaker system, radio and streaming inoperative, complete silence inside the vehicle | Medium | |
| High-voltage battery requires software monitoring Early 2024 Q6 e-tron units require continuous software monitoring of the high-voltage battery until new firmware (Q1 2025) becomes available, according to Audi. Root cause not fully communicated. Symptoms: No typical driver-facing symptoms; warning messages on the display possible | Low | |
| Driver's door lock sticks On some Q6 e-tron units the driver's door cannot be opened from outside, while other doors operate normally. Known issue on early 2024 production vehicles. Symptoms: Driver's door cannot be opened from outside even though the vehicle is unlocked | Medium | |
| Audio system dead after software update After software campaigns some SQ6 e-tron units lose all audio functions. Radio, streaming and voice control stop working. Known early-production issue. Symptoms: Complete loss of sound from all speakers, streaming and radio non-functional | Medium |
