Chronology of events

1. September 2024

   Following an increase in the number of warranty claims received for DCDC converter failure globally, JLR’s Product Safety and Compliance Committee (PSCC) reviewed the matter in September 2024. It was concluded, given the gradual progression of symptoms experienced by the customer, that the issue did not pose an unreasonable risk to safety. Further reports were received for vehicles globally in 2025 and a dedicated engineering task force was set up to understand the potential causes of the replacements and to focus on ensuring a robust resolution for JLR’s customers. From November 2025, on resumption of system access following a cyber incident, to March 2026, this task force continued working daily on the complex topic, including conducting hardware-in-the-loop testing, physical testing and virtual simulation. The task force reported regularly into JLR’s Quality Forums. In early 2026 and in parallel with this engineering activity, reviews were held with a number of government agencies in which JLR discussed the known field events as well as the progression of customer symptoms and warnings from point of DCDC failure to loss of vehicle power. On 07 April 2026, JLR received input from NHTSA clarifying the Agency’s view of the matter to be one of a safety nature rather than customer satisfaction. JLR reviewed this input in its PSCC Decision Forum on 10 April 2026 and decided to proceed in accordance with the Agency’s viewpoint. It was decided to launch a safety recall in markets where the authority’s assessment of the issue is similar to that expressed by the Agency. Affected vehicles in other markets will be considered for remedy under a Quality campaign. JLR’s engineering task force is working to develop a robust remedy for this concern and notifications will be updated once this activity is concluded. JLR has received 5,952 claims and field reports involving replacement of the DCDC converter in the US between July 2019 and April 2026. There have been no reported accidents, injuries or fires in the US as a result of this concern.
