2006 Suzuki Forenza Owner Comments

problem #15

  • 119,000 miles


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 Suzuki 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.

When putting the car in gear in either reverse or drive, there is a loud thunk and jumping feeling. There will also be an 'X' on the instrument panel next to the 'd' for drive on the shift selector. I have researched what the problem could be and it is the the range transmission sensor, it appears after researching this is a very chronic problem in the Suzuki Forenza.

Battery indicator and brake indicator illuminated on the cluster panel. When in drive, the display showing what gear you are in flashes an unrecognizable signal. Some trouble accelerating.

I bought my 2006 Suzuki Forenza brand new. The engine gave out on me in 2009. I replaced the engine once. Additional to the engine problems, one day while exiting from a major highway, the car just stopped going about 45 mph and started going about 10 mph, while a noticeable flashing square with a blinking line comes up on the gear indicator, on the dash. I almost caused an accident. I was told it was the transmission range sensor which I've now replaced two times. Note: Brand new transmission range sensors were placed and still have the same issue. When I put it from park to drive (gear), the motor jerks and feels like the motor's going to fall off. The catalytic converter has also failed to pass inspection. The A/C gave out about 2 years from the time I bought it (brand new car). It's not a reliable car, at all. Once I fix something, something else breaks. Then the paint on the door handles is chipped off, I've had two door handles break on the interior, now I hear it has electrical problems under the dash. I haven't had this issue but not looking forward to it. It constantly drains my wallet, therefore the car has been sitting in the driveway pending repairs which might not be beneficial to continue making.

My engine died while driving. My battery (which was replaced 7 months prior) also died. When I tried to get a jump start, the engine would run for a few moments before dying again. I had the vehicle toed to a lot and haven't been able to afford repairs, so I had it scrapped.

I will be driving and the shift gear will automatically shift into another gear. Or I can start the car and the gear will not go into drive and it will not go forward. I have called about getting this fixed and I was told that alot of complaints has been made for this problem on this type of car, and it is very dangerous...this will cause a automatic accident if not death.

I purchased a used 2006 Suzuki Forenza 2006in Oct 2012. The first break down was a week after purchase there was a hole in the water pump. I called the dealership and that was replace in December 2012 I was driving to work I was stopped at a red light and there was a shake in the engine it begin to jerk and did not want to accelerate. I took it to aamco where they said it had to do with the transmission switch. They fixed it after two weeks I was coming off the freeway again at the stop light my car shook and the check engine light went on I took it back and they said it was the same code that had come up the first time. They fixed it again. Then a month later the same thing happen I ended up taking it to a dealership and it was the same thing with a transmission switch. Now the check engine light keeps going off and on everytime I take it in to get looked at the same code pops up with the transmission switch. Now there saying it has to be electrical and it is safe to drive with the check engine light on.

January 2011 as I was driving on the highway the car lost all speed and then just stopped. I could not turn it over and once I got it to the shop they said the piston's went through the engine. They replaced the engine later in the month. June 2013 the same thing happened. Piston through the engine completely blown up and now they will not replace it because I am two months past my warranty. For some reason I thought there would be a warranty on the replaced engine. I bought this car brand new in 2006 and followed all the warranty repairs and maintenance.

My check engine light came on. I went to auto zone and was told it was the transmission sensor. After some research, we discovered this problem runs rampant on 2006 Suzuki Forenza models. We took it to the dealership and the manager over parts and service changed the sensor for us. However, the connector it plugs into was broken and he would look for a used one, as buying a new one means buying a whole new engine harness ($800-$900). Anytime I look up my make and model this is all anyone has to say and Suzuki will do nothing about it except charge more money to keep trying to fix it.they should be forced to recall all of these vehicles until the problem is resolved.

For approximately year prior to the incident date indicated on this form, 06/05/2012, my vehicle has malfunctioned sporadically in the way(s) I am about to describe. Since 6/05/2012, the malfunction has occurred and worsened every time I drive. Upon the initial gear shift from "park" to "reverse, " my Suzuki Forenza jerks. After the shift, the dashboard displays a "P, " despite being in reverse. When I shift to drive, I feel a jerk, and my dashboard displays a multitude of things; at times it remains a "P, " and at other times it shows "N" for neutral, "R" for reverse, a simple "D, " or a flashing "D" with a diagonal line through it. As I press the gas to accelerate, my RPM's increase, the engine revs, but my car does not move forward for a period of anywhere from 10 seconds to a full minute. The vehicle then jerks and shoots forward very quickly, which is greatly hazardous and alarming. Once my vehicle is in motion on the road, a separate but seemingly related incident occurs at various speeds- I can be on a neighborhood street or the interstate. All of a sudden, it feels as if my car is shifting itself into neutral and is still moving due to momentum. Although I immediately remove my foot from the gas pedal, my RPM's shoot up into the 6/7 range, the engine sounds as if it is going to explode, and the vehicle jerks. At this time, the dashboard displays a number of different shifts, alternating from the flashing "D, " to, "P, " and so on. I have researched this issue and found that hundreds of other Suzuki Forenza owners have experienced the same malfunction, due to the transmission sensor. It may be a relatively easy and inexpensive fix, but that doesn't lesson the severity. This vehicle has had 4 other safety recalls thus far, and I am enraged that it is has not been recalled entirely due to this widespread and extremely dangerous malfunction.
