Paul Hollick, chair of the industry body, explained that individual car and van operators reporting issues to OEMs were often told they were isolated cases. However, discussions with fellow fleet operators helped demonstrate that the problems were, in fact, more widespread.

He said: “We’re living through a period when vehicle faults are becoming ever more common, largely as a result of increasingly complex design and technology, increased levels of specification, and the widespread adoption of electric vehicles (EVs).

“Problems range in scope but frequently raise safety issues or take cars and vans out of service. As a result, some fleet managers spend a disproportionate amount of time talking to dealers and manufacturers about how to resolve them.

“Increasingly, our members share issues through a variety of AFP channels and, based on the responses received, are able to approach OEMs armed with information that shows their experiences are common across a number of fleets.”

Vehicle faults discussed at the most recent AFP Megafleets Committee, made up of some of the UK's largest vehicle operators, covered areas such as handbrakes, tyres, windscreen sensor software, alarms, traction batteries and more.

Paul said: “This is very much a transitional moment for vehicle technology – not just electrification, but the amount of software found on modern cars and vans. With greater frequency, things are going wrong, and the availability of parts and technicians is often lacking.

“We have one AFP member who has resorted to installing replacement traction batteries in their own workshops, supplied by the manufacturer under warranty, because the franchise network for the vehicle didn’t have the skills or capacity required.”

He added that the attitudes of OEMs varied widely, but AFP members quickly learnt which manufacturers were the most responsive, providing clear, honest feedback and strong support. These suppliers became trusted partners, while other manufacturers lost out.

“To an extent, almost all cars and vans supplied to today’s fleets suffer from at least some problems, so the degree of willingness a manufacturer shows to resolve issues is key. Fleets want to see decisive, timely and effective action – not to be told their issue is a one-off when it is clearly not the case.

“In recent months, we have noticed that some manufacturers have improved considerably, but others remain apparently disinterested. We have certainly seen cases where AFP members have ended relationships because support was inadequate, something which has a very real impact on brand reputation.”
