My check engine light will come on and go off every once in a while. It just went back on today. I noticed the acceleration was less when I came off a stop light almost like the car was in the wrong gear. I took it to a parts shop to see what the check engine was. It came up as a transmission range sensor. I have read that other people describing this same exact events happening in Suzuki vehicles over 70,000 miles. This could be a real safety risk to the public if the transmission was to confuse itself as being in the wrong gear at high speeds.

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 was driving down the road like normal and came up to a stop light. As I was slowing down it downshifted hard and when I tried to accelerate from the stop light it took more gas than normal to pull away. I then noticed that my check engine light was on. I took my car to an auto store the next day to read the codes. It gave the codes PO700 and PO734. When this happened I had a loss of power and acceleration and was unable to go normal highway speeds. Also when shifting from park to reverse or from neutral to drive it shifts hard and kind of clunks into gear. The next day I tried again and it was shifting just fine, but still had the check engine light. Later that day the same problems from the previous day returned. When the second incident occurred I was trying to make it back home through a heavy snow storm. If this problem had caused me to stop on the side of the road I could have been hit due to the zero visibility. I have seen many complaints about this same problem and trouble codes and I believe something should be done about this.

  • 103,000 miles
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.

  • 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.

I bought a used 2006 Forenza sedan and a few days later, the transmission range sensor went out. I just researched and there are several complaints about this issue. Also, the airbag light turned on. Suzuki need to own up to this problem and fix it. Also the 02 sensor went and needs replacement. What is going on.

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.

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.

The contact owns a 2006 Suzuki Forenza. The contact stated when the vehicle was shifted into drive an "X" mark appeared over the drive sign. The contact was not sure what the "X" mark indicated. In addition, the vehicle stalled and shook abnormally as the contact shifted into drive. The vehicle was taken to a local mechanic who advised the contact that the gear shift sensor needed to be replaced. The contact did not have the gift shift sensor replaced. The failure mileage was 70,000.

When I start the car it clunks into reverse and clunks into drive. Seems the throttle sensor and the transmission range finder is out. I have been all over the internet and it seems this is a common problem. I want to know why this hasn't been recalled. Also replace both of my front struts 6 months ago which obviously is another problem with this car. I still owe on a loan on this car and can't even get to work because of all the problems it has.

Accelerating up a hill, the check engine light came on solid (not flashing) and the "D" on the dash display where "drive" is signaled was flashing an incomprehensible icon that was not found in the owner's manual (looked like a square with two slashes through it.) the new transmission signal would flash for 10-15 miles or so starting during acceleration. The part that the dealership replaced was a "transmission range switch."

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..

I have a 2006 Suzuki Forenza. Often when I put the car into gear, it "clunks." Then when I am driving down the road, no matter what the speed, the car shifts itself into neutral. I can drive if I put it into 1st, 2nd, or 3rd gear after it shifts into neutral. After several minutes or later in the day I can get the car into drive again, but the problem repeats itself daily.

The contact owns a 2006 Suzuki Forenza. The contact stated that while accelerating from a four way stop, the vehicle down shifted on its own and then shifted into neutral. The contact had to apply the emergency brake to stop the vehicle. The vehicle was taken to the dealer for a diagnosis and the contact was informed that the transmission ring sensor would need to be replaced. This was the second time the sensor was needed to be replaced. The vehicle had not been repaired. The VIN was unavailable. The failure and current mileages were 98,000.

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.
