problem #26

  • 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.

The vehicle was stationary each time this occurred (3 times at stop lights, and yesterday, 4/27/16, in a parking lot). When I come to a stop (with foot on brake), the car starts to accelerate hard trying to go forward. Each time I put both feet on brake, and it still couldn't stop it, so I jerked it into park, then turned off key. Each time that kept me from crashing. It was scary because I have children in the car. Suzuki dealership in winston-salem didn't seem to know what it was, but said I could tow it in to get it looked at (cost $$$). then I called Suzuki dealer in raleigh nc and they said to bring it in for $110 for them to just look at it. It only happens randomly, so I don't trust that they will be able to figure it out. Please see the following weblink that described others having the same problem, but no solution (even after they took it to be worked on at Suzuki place). www.carcomplaints.com/Suzuki/Forenza/2008/engine/vehicle_speed_control.shtml thanks.

The contact owns a 2006 Suzuki Forenza. While driving 30 mph, the accelerator pedal was depressed and the vehicle failed to respond. The vehicle was taken to an independent mechanic to be diagnosed. The contact was informed that the throttle body sensor needed to be replaced. The vehicle was not repaired. The contact stated that the failure was intermittent. The manufacturer was not notified of the failure. The approximate failure mileage was 42,800.

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.

I was driving my Suzuki Forenza when it went from "drive" to basically neutral. I was driving on the interstate and was almost hit from behind because my car stalled. This has happened multiple times since and each time I've been lucky enough not to be hit. This is a seriously dangerous issue because it happens mid drive.

While in drive car suddenly switches to idle and will not accelerate with the pressing of gas peddle. It was only able to coast. The range selector part is the issue. It cannot function repeatedly since this is a reoccuring event. The only way to drive is in drive 3rd gear with the engine light on. The great concern is that will lead to an accident since the time of it ceasing to function is unpredicatable. From research it is clear that this is a nearly universal problem with Suzuki Forenzas and as a safety issue it needs to be a part properly replaced under a recall by dealers.

My transmission range sensor has failed for the third time in as many years. Each time I have it repaired by the dealership. This malfunction causes the vehicle to spontaneously throw itself in to neutral or reverse either while driving or when vehicle is at a complete stop. While driving my car suddenly jerked very hard then slowed to an almost complete stop causing the car behind me to slam on its brakes and hit my bumper. I stopped, restarted the engine and then was not able to accelerate past 15mph even with my foot firmly on the gas pedal. Like I said before, this is the 3rd time this has failed and I am glad that the person who was behind me stopped quickly and only tapped my bumper. This has also happened at higher speeds and is just an accident waiting to happen. Suzuki needs to do a major recall!! I don't understatnd how so many people are having the same problem yet it is not being investigated!

Driving down residential street vehicle stalled and began to idle high while in the "D" position. Applied brakes and tried to put it in to "P" position but dash read reverse. Turned ignition off and gears shifted as designed. 4 incidents followed this one have not had it repaired.I was putting gas in with the engine off one I got back into the vehicle cranked it and immediately the scrambled symbol appeared I cut the engine back off and tried it again and the scrambled symbol was still visible I shifted down through several gears with clunking noises and heavy jerking until I was able to find drive 3, I was able to move the vehicle at a slow pace to a parking space until I had it towed to my home. Sent it to a mechanic had throttle repaired put the very same day the very same problem occurred while my children and I were on the interstate headed home from their school. Was able to shift to drive 3 and get it off of the roadway.turned off ignition and cranked it up again the vehicle ran normally took it to an autozone so that the check engine code could be read and it came back as P0700 and P0705 have not had the funds to have it looked at by Suzuki dealership. With this as an recurring with other vehicles as well as mines something has to be done before someone is greatly injured or killed just stating the obvious. Love the vehicle but afraid to drive it even if the necessary repairs are made I don't want to feel as if im driving my and my kids death mobile.

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.

I slowed down to turn off of a busy street onto a side street. As I went to speed up to about 15-20 mph the car slammed on the brakes itself, my foot was on the gas. I put my foot on the brake for 20 seconds and then put my foot on the gas to try to drive again. The car again slammed on the brakes. I put my foot on the brake, put car in park and turned off the car. I turned it back on and was able to drive to a safe spot. I am terrified to drive it again. What if I had still been on the main road?

I thought my vehicle was stalling but the engine was still running and my tachometer was accelerating. It would stop while I was driving and the engine would rev, I tried to move but could not. I drive a busy highway speed limit 65, I had to pull off the road so I would not get hit by a semi. One day pulling out of my community, accelerating at 45mph the vehicle just stopped in the middle of two lanes, another vehicle swerved to avoid a crash. A police officer pulled over, I explained the car just stopped. He saw the symbol flashing on dash, a rectangle with line through it. Went home in 3rd or 2nd gear, that symbol is not in manual. Had a diagnosis and only O2 sensor I was having replaced. I received recall notice from Suzuki. I was scared to drive the car but had no choice, so drove slow in 3rd or 2nd, when D failed again. I had appointment for recall repairs, while at dealership was asked if I had trouble with the shifter going into gear, I said it had been happening, that I tried to get it checked, it didn't show on diagnostic performed earlier and it was dangerous. They said I need a transmission range sensor, they could fix it. I wanted to take it elsewhere, to save but I was scared to death to drive it. They said they have been seeing this in Forenza's. this is dangerous, life threatening issue. There are tsb's issued and have been incidents like mine and nothing has been done. Someone is going to cause a huge accident if they have not already, would anyone even know if a car is burned up or completely wrecked? I did contact american Suzuki to advise them of my problem so they would have it on record. I advised them that before this dangerous situation developed the shifter was getting stuck in park and that I had reported that to the original dealer and was told they could find no problem so nothing was done.

With the Forenza when you put it in gear to drive or reserve periodically it will flash a symbol in the gear indicator with a line through it this causes the car to make a loud clunking noise and barely move at all this is a big issue because the car barely moves and it does it randomly I could be driving and it losing its gear and starts to move slowly it can cause an accident with me never knowing when it will happen needs to be fixed read online lots of people are having the same issue with this car and I had a Suzuki prior and it did the same thing had the car less than a week and its doing this.

Forenza 4-cyl

  • 60,400 miles
My 2006 Suzuki Forenza switched into neutral at 60 mph on a road with no shoulder. I had my three small children in the back seat and was terrified that I would be rear ended injuring and possibly killing them as I had no power to accelerate. I was also unable to get far enough off the road because I was unable to reverse. I had to call my husband help me to get my kids out of the vehicle on the side of a busy and narrow road. This incident was caused by a failure of the trans range sensor which has become and extremely common problem with the Suzuki Forenza. This part must be recalled as it presents an immediate and ongoing risk to the to the lives of Suzuki owners and passengers as well as other drivers. It is unacceptable to have a vehicle repeatedly pose such a risk to the lives of families and for Suzuki to refuse to recall the part that is causing the problem.

When driving, the Forenza's transmission will not engage into drive. Recently, reverse has also not wanted to fully engage. Research indicates that this is not an uncommon occurrence with Suzuki Forenzas nearing 70K miles. The most common part that is malfunctioning is the transmission range sensor.

I purchased my car brand new in June of 2006. Since then I have had the transmission range sensor replaced four times. This is the part attached to the transmission which controls the speed and gear changing. My car suddenly falls out of gear and refuses to accelaerate at an appropriate speed. It refuses to take off properly. This part has been replaced twice since Jan 2012 and is currently being diagnosed for the same issue. I ahve researched several times and have found this issue to be a concensus amongst many Forenza 2006 owners. This vehicle needs to be recalled due to this faulty part. It is unsafe and endangers not only the life of the driver of the vehicle but also others.

I was driving on the freeway when all of a sudden my car stales.. thank god I was close to the right shoulder. I just got the car back from the mechanic and spent 500 to fix the timing belt, new battery, valve, oil change.. I took it to them for this problem in the first place and they couldn't figure it out. I called Suzuki corporate and they said there is nothing they can do. I explained the huge liability if my call just stops in the freeway.. they offer to hold my hand through the process. Suzuki needs a rude awakening. Recall on the transmission range sensor.. I am not sure if that is the problem because no body at the shop could figure it out. But I see on these forums I am not the only one..

Today my wife noticed that the battery indicator and brake indicator lights illuminated on the cluster panel this morning while driving to work, as well as the speedo needle bouncing around when coming to a stop. I picked up the car and drove it to auto zone to see if there were not any obd II codes stored. I too noticed the brake/battery lights, as well as the speedo needle would jump when I used my turn signals. I got it to auto zone and there were no codes stored. It was after the code scanner was hooked up my real problems began. When putting the car in gear (either D or R) it would slam into gear, the speedo didn't work and to top it all off, the car had no acceleration. I had this issue before, and it turned out it was the transmission range selector. Well, that was replaced no less than 10K miles ago. Please, someone place this car on the lemon list so I can recoup my losses. When there is next to no acceleration, it can cause an accident because the car can not move fast enough to avoid getting clipped (or worse).

A malfunction occurs when I attempt to shift gears from park to any other. 1. it makes a loud, deep sound, similar to "thunk-thunk" and if I don't have my foot on the brake hard enough, the car lurches. 2. the dashboard signal for pdrn etc randomly changes to a weird symbol that is not any letter in the american alphabet. 3. it makes a revving sound which should indicate a higher velocity when in fact it is at a lower velocity. 4. it will not accelerate properly. When entering a high frequency road or highway, I have to floor the gas pedal to go normal speed then maintain it. 5. it shifts out of drive into neutral while I am driving and independently of my activity, thankfully approximately only about once every month. 6. the check engine light is always on. 7. the mechanic said it was related to the transmission but was called a range something or other. 8. I notice these problems more in stop-and-go city traffic than on long uninterrupted distances. 9. I consider these random car behaviour problems unstable and unsafe. 10. to any driver new to handling/driving my car, I would have to explain its quirks for them to drive and not have a tragic vehicular accident involving the improper response of my car to normal use. 11. the warranty ran out long ago. It was only for three years. The problems started occurring after the warranty expired, of course. 12. it will cost me about $200 to get the range whatchamacallit fixed, $200 of which I believe Suzuki should pay. Unrelated problem, sometimes the seatbelt buckle unclicks itself.

I have had so many problems with this car!! it started out as I was shift into or past reverse. Now it shifts on it's own while driving, while pulling into traffic, while at stoplights/stop signs. You will be driving and it will jerk and put itself into park but still go. It's like driving a stick shift without letting off the clutch. This is a very dangerous vehicle to drive. You don't know when it's going to act up. I have my daughter in the car and wait until it's absolutely clear to pull out due to this. Tonight (10/13/11) I was driving, hit a bump in the road that I've driven over a million times and simultaneously, my brake light and my battery light came on. I drove to my destination with my lights dimming slowly and pulled into the spot and the car died. I spoke to the local Suzuki dealership and asked the service tech is he gets alot of issues with this sensor and he says "the numbers are higher than they should be for this car. "
