How it works and why it fails

Driver assistance and automatic emergency braking

Automatic emergency braking, adaptive cruise control and lane departure warning use radars and cameras. A dirty or poorly calibrated sensor, or immature software, can disable them or, conversely, cause braking for no reason, and some manufacturers have corrected this with campaigns.

What to do

Keep the front radar and the windscreen camera area clean. After replacing the windscreen or work on the front end, have the sensors calibrated. If the car brakes on its own for no reason, document it and take it to the official dealer: it is usually fixed with an update.

General explanation by MotorFiable. The specific faults of each engine and car, with their sources, are on the linked pages.

Problems with driver assistance systems by car

Faults documented on specific cars, which occur with any engine. From most to least important.

  1. 1Critical severityVery frequentFrequency: Very frequentToyota Auris IIThe Takata driver's airbag inflator can degrade and fragment when deployedOn units built between 2006 and 2017, the propellant in the Takata inflator of the driver's airbag can degrade over time and with humidity; if the airbag deploys, the inflator can rupture and throw metal fragments at the occupants. Toyota fixes it by replacing the inflator free of charge at the official dealer.
  2. 2Critical severityOccasionalFrequency: OccasionalMazda 3 IVSmart Brake Support can brake the car unintentionally while drivingOn cars built between November 2018 and October 2019, an unintended activation of the Smart Brake Support automatic braking system can stop the car unexpectedly while it is moving, with a risk of the vehicle behind running into it. Mazda inspects it free of charge at an official dealer.
  3. 3Critical severityOccasionalFrequency: OccasionalMazda CX-30Smart Brake Support can brake the car unintentionally while drivingOn cars built between November 2018 and October 2019, an unintended activation of the Smart Brake Support automatic braking system can stop the car unexpectedly while it is moving, with a risk of the vehicle behind running into it. Mazda inspects it free of charge at an authorised dealer.
  4. 4Critical severityOccasionalFrequency: OccasionalToyota C-HR IThe pre-collision system radar can fail without warning the driverOn vehicles built between 2020 and 2021, a faulty radar sensor installation can stop the pre-collision system (PCS) from detecting a vehicle ahead, with no warning or assisted braking and no message that the system is not working. Toyota fixes it by inspecting the radar at an official service centre.
  5. 5High severityOccasionalFrequency: OccasionalAudi Q3 IICalibration errors in the driver-assistance sensorsA specialist reliability profile documents errors in the Q3 II's adaptive cruise control, lane-keeping warning and automatic emergency braking, which it attributes to poor sensor calibration.
