Vehicle sporadically stalls while driving, not a stop light or sign but while the car is actively being driven and the accelerator is depressed. Most recently it has begun to rev up between 4,000 and 5,000 rpm. When this happens, I put the car in neutral to try to get it back to normal. 2 days ago when this happened it caused me to hit a pot hole hard enough to break my driver side ball joint and lower control arm. I see recalls for other, same year model Suzukis that experienced this same issue. I don't think I should have to pay to repair a known mechanical defect. There is also an NHTSA id describing this issue as well. It is extremely scary to have the car reving that high and trying to control it. I am thankful that I only hit a pot hole and not another vehicle or worse.
I brought a 2006 Suzuki Forenza on July 11, 2006. In two or three days I noticed something wrong in the way it was driving. I took it back and the general manager drove the car and stated nothing was wrong. The next day the car would not start. I took it to the dealer they stated it was a software problem and it needed new spark plugs. The car wouldn't start again. I was told it needed an upgraded software. The car doesn't start it sounds as if it wants to cut off and it drives rough and stalls. This car is brand new and montgomery keystone motors were fully aware of this and still decided to sale me a lemon. I have contacted an attorney regarding this.
Rough idling problems / no start problems after owning new 2006 Suzuki Forenza three days. First time happened at gas station. Took four attempts to get car running . Happened intermittently. Took car to dealership. Replaced spark plug and installed new computer. Same problems occurred two days later. Have had newer problems occur. Car on four occasions has almost died while driving, warning lights coming on when they shouldn't. I contacted manufacturer about the rough idle/no start problem. Am in process with them now to try to get a refund. Problem is thought to be with software glitch downloading improper fuel data into cars computer. Rep from manufacturer said software downloaded usage of summer fuel rather than winter which is why I have had the problem with intermittent rough idle , no start, car trying to die while driving. It is my understanding there is a fix for automatics but not for manuals like mine. Although rough idle and no start problems are more of an annoyance , the car trying to die is more of a concern which I feel is a safety issue.
