NHTSA 5-Star Safety Rating
The 2021 Audi A6 Allroad has 8 recalls, the most serious involving liquid spilled in the rear seat reaching a gateway control module and causing a sudden loss of engine power while driving.
On the safety equipment side, the passenger airbag may not have been manufactured correctly along its score line, meaning it could fail to deploy properly in a crash or send plastic fragments into the cabin. A separate recall covers rear seatbelt retractors that may not properly secure a child restraint system. There are also two overlapping rear visibility concerns: a software error can prevent the rearview camera image from displaying when reversing, and a related infotainment issue can also leave the camera screen blank. The instrument panel display can fail due to a software fault, potentially hiding the speedometer or warning lights while driving. On the chassis side, rear axle misalignment can cause uneven or accelerated tire wear. Rounding out the list, a brake fluid reservoir cap may be incorrectly labeled, which can lead to the wrong fluid being added and reduced braking performance.
