A hard starting condition may be due to low fuel pressure.

Correcting this condition may require updating the PCM software.
2005 Suzuki Forenza Recalls (Recent)
RepairPal Expert Overview:
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.
RepairPal Expert Overview:
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.

2005 Suzuki Forenza Reviews
Very disappointed in the gas mileage. Sometimes it's taking 2-3 tries to start up. A/C compressor just went out. I didn't do any research prior to purchasing so I paid much more than the average.
Forenza Wagon with maual transmission.
Paint chipping from side view mirrors.
Clutch and slave cylinder replacment at 54,000 miles - $1,450
The value of the car is reflective of it's book price. Low.
In this case you get what you pay for.
for a compact car with a 2.0L 4 cylinder to get such poor mileage is bizarre. it's not a barn burner for sure, so it seems like the mpg would be better? there's no check engine light that the dealer says would be on if there was a problem, but seems like something is wrong
