“Three weeks after I purchased my Forenza the check engine light came on, so I took it in to the dealership & was told it is a known problem with the Forenza .the problem had to do with the '02 sensor' and currently there is no fix for the problem. At that time they reset the code problem. Each time the problem recurred I went back to the dealership and they caused the light to turn off. …”
NHTSA complaint #10171850, filed 2006-10, 100 miles“Within the first three days of purchase,started to have trouble starting the car in the mornings. Took the thing back. They have had the thing almost two weeks now. They cannot tell me anything about the problem. All they have said to me is you have a rental .”
NHTSA complaint #10160312, filed 2006-06, 100 miles“I have a 2006 Suzuki Forenza and have issues with the transmission range sensor and the airbag light staying on. I have looked online and there are several complaints about the same issues. Whenever the car is put in reverse or I have to go down the gears to drive, the car jerks and then drives very slowly. It is as though I am driving a stick-shift and not letting off of the clutch. The whole car jerks when this happens. I do not and have not had the money to fix this problem. The dealership told me it would $350.00 plus labor to fix this part alone. …”
NHTSA complaint #10392595, filed 2011-03, 63,000 miles“I bought a new 2006 Suzuki Forenza from a dealer on 23 may 2006. After one week with the car, I began having problems in that it does not start after it sits for a while. I called the salesman on 2 jun 06 and told him that for the third time that week, it didn't start. He didn't inform me of any problem with the vehicle and just stated it shouldn't happen and to have it towed in. I went back to the vehicle and it finally started but I have had the same problem starting it every day since. …”
NHTSA complaint #10160358, filed 2006-06, 350 miles“Ahhh yes...the range sensor going out. My car started doing this in october 2010 and I was told that I need a new sensor too. My car jerks when this acts up and when it is gear, you can see the both the r and the d on the instrument panel. I took my car to midas and the mechanic (that works on my car) take a look at, he showed me where the sensor is (if you're facing the engine it's the little black round looking thing with a handle and yellow stripe on it). He did something to it and it ran fine for a few days and then did the jerk and the engine light came on again. …”
