This page covers 3 recalls, 20 owner complaints and NHTSA crash-test ratings for the 2024 Audi Q4 E-Tron.
5/5 Overall
NHTSA 5-Star Safety Rating
Electrical system complaints dominate what 2024 Q4 e-tron owners report, covering a range of behaviors that interrupt normal driving. Several owners describe complete or near-complete electrical failures, including loss of vehicle function while parked at high battery charge. A recurring pattern involves the driver seat occupancy sensor cutting power mid-drive when the driver shifts position, causing the car to abruptly shut down during maneuvers like reversing. Multiple owners also report AWD system malfunction warnings appearing repeatedly, with some returning to the dealer several times for the same alert without a lasting fix. A smaller but notable pattern involves braking irregularities: owners describe sudden, uninstructed hard braking during acceleration from a stop, after which the car drops out of gear and requires a restart. One report describes regenerative braking failing to respond at low speed before the wheels locked abruptly.

By System
The 2024 Audi Q4 e-tron has 3 recalls, the most serious involving the on-board charger, which can fail to keep the 12-volt battery charged and cause a sudden loss of drive power while the vehicle is in motion.
On the charging side, a separate issue affects the AC charging system: the outlet or charging cable can overheat during a charging session, raising the risk of fire. For exterior lighting, incorrect software in the headlight control module can cause the parking lights to behave unexpectedly when the headlights are on and a turn signal is activated, reducing how visible the vehicle is to other drivers.
