Completion rates

  • Volvo recalled all 2019 and 2020 models for a software issue with the AEB sensor inside the windshield, on March 12th accounting for nearly 750,000 vehicles worldwide, 121,605 of which are in the US. The recall is expected to begin May 1st 2020; As mentioned above, in 2019 Volvo had 0 software recalls.
  • FCA is recalling 318,537 vehicles in the US, across 11 models, for 2020 and 2019, due to a software error that can cause the rear view camera image to remain displayed after the vehicle has been shifted out of reverse. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, “Rearview Mirrors”. The solution is an update of the radio display software, delivered by a dealer. The recall is expected to begin on May 22, 50 days after the OEM identified the issue.
  • As of January 30th, 2020, certain 2019 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles (148,055 units) are being recalled for a software update on the software they received in the previous recall, for the Electronic Brake Control Module (EBCM). The first software has an error, and as a result, the vehicle’s electronic brake assist may be disabled. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 126, “Electronic Stability Control” and 135, “Light Vehicle Brake Systems.” The recall began February 24th, making the remedy promptly available in 25 days.

Reflections..

As the number of software recalls will keep rising in the foreseeable future alongside the number of vehicles affected, OEMs must become quicker and more agile in reporting and fixing them in a timely manner. The outcomes of this approach benefits the entire industry by aiding in the reduction of:

  • Unremedied vehicles on the road, consequently reducing crash risks;
  • OEMs overall direct recall costs;
  • Trips to the dealer for each vehicle owner;
  • Vehicles in operation are not compliant with the requirements of federal motor vehicle safety standards;
  • Costs associated with non compliance mentioned above;
  • Indirect costs OEMs might occur in resolving software issues — reputation and brand image, repeated recalls, potential settlements and legal fines.
  • Dealer network efficiency and overall capacity and effectiveness, in having to address only hardware recalls;
  • Overall completion rate numbers and full control over the rate;
  • Software issue fixes: timely, effectively and securely.
