This shocking footage emerged online after Russel Jones of Bristol took his Kia to a local Kia dealer to fix a problem with the windscreen wipes.
On picking up the vehicle, Russel was told by branch staff that the parking sensors and electric wing mirrors were broken.
Russell said: “I sent my car in as the window wiper was not working.
“They then told me they’d found loads of other problems which needed fixing, but it was becoming too expensive so I told them to stop as I’d found somewhere cheaper online.
“I think they’d created all the other problems themselves.
“I told them to stop so I could go elsewhere, but they carried on anyway without my consent.”
Angered by the footage, Russel later posted an edited version of the footage on YouTube where it has been watched more than 7,000 times.
On posting the video, he wrote: “Wessex Kia Bristol broke my car’s parking sensors, among other things, and tried to get away with it by completely lying about it.
“For the record my parking sensors worked completely fine when I took it in and I took it in due to my windscreen wipers malfunctioning.”
During the video, one of the technicians can be heard saying of the sensors: “He might not even use them.”
The other mechanic replies: “Thing is I don’t know what else that powers, it must power something else.”
“Wouldn’t we be better off just [inaudible]?”
“But his parking sensors don’t work – he’ll know his parking sensors don’t work won’t he?”
“He will when he hits something – it’s not our fault is it.”
Kia Wessex has since said that they had blown the fuse which supplies power to the rear parking sensors during an “investigation of the wiring.”
Mark Hayward, general manager of Kia Wessex, said: “We replaced the fuse and all worked correctly.
“We did apologise as it was our fault the fuse blew, through our first testing of the wiring.”
