Early KB Centuras also experienced quality issues with interior fixtures, with door trims cracking, and torn vinyl trim near stitching lines not uncommon. A story going around is that no Centura models were fitted with starter motor relays, which simply put the load onto the ignition switch when cranking instead, which reduced the ignition switch life in some cars. The starter motor relay is attached to the firewall above the starter motor in all models. Traction in wet weather proved to be poor, with an open differential, relatively large six-cylinder Hemi engine and very light weight over the rear wheels.
