Detroit - Mazda is recalling about 174 000 small cars in the US because the seats can change angles suddenly, making the vehicles hard to drive.
The recall covers the Mazda 2 subcompact from the 2011 model year and the 2010 and 2011 Mazda 3 and Mazdaspeed 3 compacts.
'Increased risk of crashing'
The company says the seat height adjustment links can break or detach from the seat frame, changing the seat angle and increasing the risk of a crash.
Dealers will inspect the seat links and either install a reinforcement bracket or replace the whole seat adjustment unit. The recall is expected to start on March 31.
