Kia Rondo: Fuel System
Affects Kia Rondo · 2007–2008 — about 5K vehicles.
The hazard
On certain vehicles, an incorrect dimensional characteristic of the fuel pumps upper body can result in a misalignment of the armature shaft, which may cause some fuel pumps to experience poor brush-to-commutator contact conditions. In addition use of a 10 percent ethanol blend fuel can cause a film built-up that creates a high resistance between the brush and the commutator. The misaligned armature shaft prevents the brush and the commutator from making sufficient contact to overcome the high resistance film build-up between the brush and commutator. As a result the fuel pump may produce less pumping pressure than required to supply the fuel injection system resulting in poor starting or hesitation. Loss of propulstion, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash. Correction: Dealers will replace the fuel pump assembly.
