Figures show that police are unable to solve three out of four car thefts.
In the 12 months to June, more than 100,000 vehicles were seized without a perpetrator being identified.
Compared to the previous year, the value has increased by a fifth.
A total of 107,451 reports of stolen cars remained unsolved – 77 percent of all cases.
At the Met Police in Greater London, the proportion rose to 86 percent.
In the South Yorkshire and Essex forces, 83 per cent of car thefts were unsolved.
Only four percent of cases nationwide resulted in someone being charged or cited.
An analysis of Home Office figures by the Liberal Democrats shows that an average of 5,916 crimes go unsolved every day.
This corresponds to an increase of ten percent compared to the previous year.
Alistair Carmichael, Liberal Democrat home affairs spokesman, said: “As the vast majority of burglaries and car thefts continue to go unsolved, it is clear that the Conservatives are failing to get the basic things right when it comes to stopping crime .” Thousands of victims are cruelly denied justice and feel unsafe in their own homes as criminals get off the hook every day.
“Yet the Interior Minister appears to be asleep at the wheel while communities pay the price.”
Meanwhile, thefts from caravans and motorhomes have tripled in some parts of the UK as criminals cash in on the camping boom, police figures show.
