This page covers 3 recalls and 25 owner complaints for the 2015 Audi A4 Allroad.
On the 2015 Audi A4 Allroad, engine and powertrain complaints make up the largest share of owner reports, with steering close behind. On the engine side, owners report issues with the turbocharger cooling pump failing, specifically the auxiliary pump that runs after shutdown to cool the turbo, with some describing extended waits for replacement parts. Powertrain reports include concerns about unintended acceleration and a rolling-forward behavior when the transmission is shifted into reverse on a downhill grade. Steering complaints describe the wheel becoming progressively harder to turn, with at least one owner reporting that the difficulty became severe enough to make highway cornering a real struggle before the car would respond.

By System
The 2015 Audi A4 Allroad has 3 recalls, all carrying fire risk: wiring in the auxiliary heater circuit can corrode and overheat, and the electric coolant pump can become blocked or short-circuit, in both cases generating enough heat to start a fire.
All three recalls share the same core danger. The auxiliary heater's electrical connector can develop corrosion that causes the wiring to overheat and melt. Separately, the electric coolant pump on 2.0L turbocharged models can become clogged with debris from the cooling system or develop an internal short, causing the pump itself to overheat. Prior repair attempts did not fully resolve the coolant pump issue, which is why it appears across more than one filing.
