2004 Suzuki Forenza Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2004 Suzuki Forenza


The Check Engine Light may illuminate accompanied by a code P0133 (bank1 O2 sensor) stored in the powertrain control module (PCM). This is commonly caused by a failed air/fuel sensor. Our technicians tell us a revised a/f senor and (PCM) software upgrade may be necessary to correct this concern.

The head lights may stop working due to a failed connection at the multifunction head light switch. Our technicians tell us there is a harness connector repair kit available which should be installed in conjunction with dielectric grease to seal the connector. 2004-2006 models have been recalled for low beam and daytime running light malfunctions.

A lack of power may develop, accompanied by an illuminated Check Engine Light  with fault code P2106 stored in the powertrain control module (PCM). This fault can be caused by a throttle actuator which has only limited movement. The correction for this condition includes replacing the throttle actuator and updating the PCM software.

Increased resistance due to poor contact between the terminals of certain wires can generate heat that can melt the splice pack used to connect the power circuit wires for the headlamps. This can result in intermittent or total loss of low/high beam headlamp function. If the headlamps fail to function, this will lead to reduced driver visibility, increasing the risk of a crash. Dealers will reconnect the affected wires with two heat-shrink crimps to correct this problem. The Suzuki recall number is NU.

A melted splice pack in the wiring may cause the low beam headlights or daytime running lights not to function. Insufficient lighting could reduce visibility and increase the potential for a crash. Dealers will splice the power circuit wires for the low beam headlights and DRL free of charge. The recall began October 31, 2007. The Suzuki recall number is NB.

The brake light switch may be knocked out of adjustment if an upward/rearward force contacts the brake pedal. If this happens, the lights would remain on whether or not the brake pedal is applied, and will remain illuminated even when the key is switched off. This condition could drain the battery if left, and increase the risk of a rear end crash since drivers will not know when the brakes are applied. This condition would also disable the automatic transmission torque converter clutch, cruise control, and the traction control system. Dealers will replace the brake light switch. The recall began March 16, 2005. The Suzuki recall number is KF.

I have had my 2004 Forenza for almost 7 years now and could not have asked for a better deal. There have not been any major problems. I am starting to see some minor things happening now but it comes with age!
