How a UK vehicle safety recall works on paper: notification, the 90% threshold and what gets published

When a car maker (or the supplier of a part fitted after the production line) finds a safety defect, the paperwork that follows is governed in the UK by codes of practice issued by the Driver and Vehicle Standards Agency (DVSA). The code covering vehicles and their original-equipment components was updated 6 March 2024; a companion code for aftermarket parts carries a date of 14 May 2021. Neither is a newspaper story about a single campaign - they are the standing rules that describe who must be told what, how quickly, and what the public gets to see.

This explainer walks through that process as the documents describe it: how a defect becomes an official recall, how owners are contacted, when a recall is counted as closed for reporting, and what appears in published lists. All figures below apply to the UK market and come from the DVSA documents named.

The notification duty and the investigation window

The legal trigger is confirmation of a safety defect, not the start of a recall campaign. The vehicle code states the obligation plainly: "Where a producer or distributor is aware of a safety defect with a product there is an obligation to notify DVSA." The code links this duty to the General Product Safety Regulations 2005 (GPSR), the UK product safety legislation, noting that notification "ensures that DVSA are aware of the issue at the earliest stage" and so complies with Part 2, section 9 of the GPSR.

When DVSA passes on a defect reported by a member of the public, the producer is expected to investigate and respond quickly. The code asks producers to "respond to DVSA in full as soon as possible, normally within 28 days." If that window cannot be met - because testing takes longer, or a vehicle maker abroad has to be involved - the producer must explain early and keep DVSA updated. The aftermarket code sets the same rhythm for parts: "Producers and/or distributors will have four weeks to respond to DVSA with their initial findings/information." The investigation must, in the vehicle code's words, be "expedited in line with the potential risk that is being considered."

Not every defect becomes a safety recall. Where the safety-defect criteria are not met, the vehicle code lists two non-code actions:

• a Non-safety Recall (non-code action), for defects that "Does not meet the criteria for safety; however it would be in the customer's interest to have the work completed"
• a Service Campaign (no recall), where "There is no safety risk, and it is not deemed to be in the interests of all users of the vehicle"

Reaching owners, and phasing

Once a recall is agreed, DVSA has a say in how it is communicated. The producer's communication is treated as a "call to action", and "DVSA must be given the opportunity to comment on the content of the communication prior to instigating a safety recall." A single letter is not assumed to be enough: the code expects that "a number of communications may be necessary to ensure that the message has been received and understood by the user." The notification process includes a provisional contact plan agreed with DVSA, reviewed against response rates; if those rates run roughly to plan, "it would be expected 3 notifications per motorist would be seen as reasonable."

Large campaigns can be spread out, but not on the producer's word alone. "Where the recall involves large numbers of vehicles or the remedy is extensive or dependent on a limited parts supply the recall may be phased, however this must be agreed with DVSA." The phasing must rest on "an understanding of risk across a product range - including its usage profile."

The 90% closure threshold

Producers report their progress to DVSA at three-monthly intervals until the recall is complete, or until DVSA agrees it can be "closed for reporting purposes." That closure has a numeric benchmark: "A recall is considered to be closed for reporting purposes when the producer can show that a high proportion of vehicles (normally 90%) believed to be in service have been rectified and the remaining safety risk is low." The 90% figure is not fixed: DVSA, with input from the producer, "may adjust the completion rate for recall closure (to a level lower or higher than 90%)," weighing factors such as the age of the vehicles and the quality of the owner data held against them.

Closure here is an accounting term, not an amnesty. The code notes that a recall closed for reporting "is still in place, and producers or distributors are still expected to act upon it should a vehicle be presented, even though active management of the recall may have ceased," and that its details would still appear in published material.

What gets published

Transparency is written into both codes. For vehicles, "All Safety and Non-safety Recalls will be published on GOV.UK - at least as a list of recalled vehicle and component types," with all recalls also available monthly to those who sign up for alerts. For aftermarket parts, "All safety recalls will be published on DVSA's website" and "published bi-annually in the recalls e-bulletin." DVSA also reserves "the right, under ministerial authority, to publish at any time, information of public interest" in the aftermarket context, after consulting the producer concerned.

Published lists answer a type-level question, not always an individual one. In a DVSA blog post dated 14 October 2024, the agency explained the limit - the searchable list does not "tell you if your individual vehicle or vehicles have had any recalls either outstanding or dealt with" - and noted how that gap is being closed: DVSA has "started working with vehicle manufacturers for them to share their data with DVSA on outstanding recalls for individual vehicles," with the shared data appearing on the MOT History Service. At the time of that post, the commercial-vehicle producers sharing data this way were listed as MAN Trucks plus Ford, Mercedes and VW vans.

How to check a vehicle yourself

A reader can verify the picture without taking any manufacturer's word for it:

• search the recall list DVSA publishes on GOV.UK for the vehicle type in question
• look up the individual vehicle's history on the MOT History Service by entering its registration number, where any manufacturer-shared recall data DVSA holds will appear
• sign up for DVSA's alerts, which make recalls available monthly
• for a part or vehicle bought for use outside the UK, check the recalls list for that market's own authority, since publication arrangements differ by market

Because DVSA revises its codes and data services, check the dates on the GOV.UK pages before relying on any figure in this piece: the vehicle code carries an updated date of 6 March 2024, the aftermarket code 14 May 2021, and the data-services blog post is dated 14 October 2024.

To check the result for yourself, read the DVSA codes of practice on GOV.UK and search your vehicle's registration on the MOT History Service; if you own a commercial vehicle, note that individual-vehicle recall data there is limited to the manufacturers that share it, as listed by DVSA in the October 2024 post.
