Vehicle Speed Control Problems of Suzuki Forenza - part 2

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.

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).

The car has a big problem changing gear and when I drive sometimes it slows down and couple of times I almost got into accident because of car slowing down and at times when I try to switch gears it clunks so hard and it is becoming very dangerous driving with my kids in the car because either the car wont change gears or looses speed when I am driving and that can cause a big accident and I call Suzuki dealership and its not under warranty, there should be a recall on this vehicle it is very dangerous and they are the ones making poor quality parts for the engine, and from other consumers I am not the only one with the same issue and worries. Please help!.

Car accelerates very slowly. It will stall out if the gas pedal is floored. The check engine light will blink until the car is turned off. The check engine light will stay on for sometimes a few days at a time and then turn off. Others have complained about the transmission range sensor going up many times.

I was driving down the expressway and I was doing 65 mph and my car started stalling as I pressed the gas then I floored the gas because my car was starting to reverse down the expressway all of a sudden my car froze and my computer on my dash had all the letters scrambled for drive, reverse, park etc and had a line through it I was soooo scared I had a big truck behind me.

When turning my car on and putting it into reverse, the check engine light came on and my car jerked into gear and where the r should appear for reverse on the dash, all the letters were scrambled together. The car drove in reverse and then when I put it into drive, it jerked again and then would hardly accelerate. After driving the car for a couple minutes, turning it off, and turning it back on, it would finally accelerate but the check engine light would still be on and the gears would still jerk. The check engine light would go off after a couple days and everything would be fine and then it would all start again. Then my car is starting to switch over into neutral when driving 60mph+ and now it will do this multiple times when driving at any speed. When it switches over to neutral like this while I'm driving, the d for drive on the dash will become scrambled like it does when it jerks into reverse. The problem is getting worse.

I was driving down a busy street in stop and go traffic. While stopped at a stop light, my vehicle made a very loud "clunk" noise, lurched forward and the check engine light came on. When I attempted to accelerate after the light turned green, I had to push the gas pedal almost to the floor to get the vehicle to move forward. I pulled over and parked, turned the vehicle off, waited about a minute, turned the vehicle back on, and the problem had gone away although the check engine light was still on. A day or so later, while I was driving on the highway going approximately 65 miles per hour, the vehicle made the "clunk" noise, lurched forward and the check engine light came on again. This time, because I was already in motion, the rpms jumped up above 3000, which is very high for a 4 cylinder engine only going 65 miles per hour. Again, I pulled over, turned the vehicle off, waited about a minute, turned the car on and was able to drive the vehicle normally again although the check engine light remained illuminated. This issue has been happening randomly about 20 times a year over the course of the last 2 1/2 - 3 years.

Trying to shift into gear the car jerks and the display blinks, not indicating what gear the car is in. The only gears that show are d and p. When trying to accelerate the car moves very slowly and doesn't go any faster than 35-40 mph. Diagnostic test show it is the tramsmission range sensor. I see that this is a common problem in this model vehicle and thinks it should be recalled and fixed at the expense of the dealer not the consumer. This car has only had problems from the beginning and the manufacturer needs to realize this and assume some responsibility for their product.

While driving, car suddenly lost power, unable to accelerate or change gears on it's own, and when I shift from drive to park, it felt like my car got hit, a very hard "bang" and same when shifting from park to reverse or back to drive. Ck engine light appeared. After stopping and turning car off for aprx. 10 minutes then turning back on, light was still on, but now car was accelerating and changing gears. Got the car to the Suzuki 112 dealership in medford, NY and they said codes po700 & po705 were present. They diagnosed a failed automatic transmission range sensor / switch assy. The service advisor told me this is a very common problem, and he replaces 4-6 of these per month between the Forenza and reno model Suzuki vehicles. Service advisor stated this is not covered under the power train warranty since this is just a component that is mounted to the transmission, not actually inside the transmission. $216. 63 later, the dealership mechanic removed and replaced the part. Note: this is the 2nd time I had this problem, but 1st time they couldn't diagnose as check engine light shut itself off before they got to check it out.

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".

When driving my 2007 Suzuki Forenza the engine light comes on and I lose all power in movement. If I stop and start driving again I have to push the gas pedal to the floor to get the car moving again, it takes off very slowly and I cannot get the car to go over 25 miles per hr. When I take it in to a mechanic they run tests but say there is no problem found. I believe this is a manufacturer defect. I have read on the web of many others having the same problem. I fill that this is unsafe and would like this investigated if possible.

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.

The contact owns a 2008 Suzuki Forenza. While driving approximately 40 mph the vehicle began to decelerate. The vehicle was pulled over and shut off. Upon restart the vehicle operated as normal. The failure recurs approximately every 20 minutes in which the vehicle needs to be shut off and restart. The vehicle was taken to an independent mechanic where she was informed the throttle body needed to be replaced. The vehicle was not repaired. The failure and current mileages were 51,094.

I noticed my car having difficulty accelerating and it would occasionally feel the engine jump while driving. The check engine light was on. I was going down the interstate when the engine shut itself off. Luckily it turned itself back on and I was able to safely accelerate to speed. The shop said that it was the transmission range sensor and the transmission control sensor. A year ago the car was displaying funny symbols and would not start occasionally. Again the same sensors had to be replaced. A third time the car check engine light came on and the car was again having difficulty accelerating. The acceleration issue and the light are intermittent, it has now again begun doing the engine "jump" it is scary being at a light and not being able to move. It is very scary stopping to turn left into my apartment complex and not knowing if my car will respond when I have a gap in traffic to turn. Took it to a shop today to find out that the codes from the engine check light are again the transmission range sensor and the transmission control sensor. The car has under 65k and I have had these issues three times. I am thankful that it has not caused a major accident.

The contact owns a 2007 Suzuki Forenza. While driving at speeds of 15 mph and depressing the brake pedal, the vehicle oddly accelerated. The contact was able to stop the acceleration by shifting into neutral gear and applying the emergency brake. The vehicle had not been inspected. The manufacturer was not informed of the failure. The approximate failure and current mileages were 34200. Updated 05/19/2010. Updated 06/03/bf the consumer has since traded the vehicle. Updated 06/09/jb.

The contact owns a 2007 Suzuki Forenza. He stated that upon starting and putting the vehicle into reverse, the engine would idle very high and the vehicle engaged into reverse rapidly at speeds of 20 mph. There were no recalls for the failure. He had not taken the vehicle into the dealer as of yet due to the distance. The failure and current mileages were 31,000.

Car accelerates on its own when it does brakes don,t work acts like anti lock bad has just hard pedal car will accelerate until it decides to stop last time up to 105 mph for about 20 miles it has happened twice on high way 3-4 times in city took car to dealer they said it could be trans control module or engine control module they replaced trans control module told me car was fixed . I asked them how do they know its really fixed because its a intermittent problem . They assured me its fixed I called Suzuki to see how to be assured its fixed because my 17 yr old daughter drives the car they told me to drive it and let them know if it happens again, so I thought well lets see if someone can get killed and drove car as they said car was ok for about 3 weeks well my daughter was driving car again and it happened again this time in city she had to run 3 red lights and finally got car to stop the customer complaint person at Suzuki told me that if a serious injury accrued because of this problem that they would let the insurance company work it out, I asked so what does someone have to get killed before you will do something about this issue ( this is a serious issue ).

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.

The contact owns a 2007 Suzuki Forenza. While driving approximately 45 mph on normal road conditions applying pressure to the accelerator pedal, followed by a low power response, the engine warning light illuminated intermittently. An independent mechanic stated that the failure was contributed to the throttle body. The vehicle was taken to an authorized dealer for a second opinion and the technician stated the failure was related to the throttle body and needed to be replaced. The wiring within the throttle body was replaced. The failure continued after the vehicle was repaired. The throttle body has been on back order for quite some time. The vehicle will be repaired when the part becomes available. The contact is aware of the safety risk involved. The failure mileage was 57,800 and the current mileage was 60,000.

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 my 2005 Suzuki Forenza uphill going 35 mph when it suddenly stopped accelerating and sounded as though it had shifted into neutral. However, the car was still in drive. The check engine light also came on. Leading up to this incident, I experienced rough jolting when my car (which is an automatic) was downshifting from third to second gear. I feel very unsafe driving, because I don't know when the car will suddenly stop accelerating. I have since been told that the problem is likely the transmission range sensor.

The contact owns a 2006 Suzuki Forenza. While driving 65 mph he experienced unintended vehicle acceleration and the vehicle stalled. An authorized technician replaced the timing chain, water pump, timing belt valves , and the cylinder head. The timing chain separated twice after the vehicle was repaired. None of the repairs have corrected the failure. The vehicle identification number was unavailable. The failure and current mileages were 51,000.

The contact owns a 2006 Suzuki Forenza. Whenever the contact depressed the accelerator pedal, the vehicle would not move; however, the engine would rev loudly. She took the vehicle to the dealer and they stated that the throttle assembly was not allowing any gas to enter the engine, which caused the vehicle not to run at times. The dealer stated that this was a very common issue and no recalls were issued. The contact believes that she should not be responsible for the repair and a recall should be issued. The failure mileage was 40,000 and current mileage was 55,000. Updated 05/15/09 the consumer stated the air bag light illuminated. Updated 05/18/09.

The contact owns a 2007 Suzuki Forenza. Two months after purchasing the vehicle, the contact received a recall notice for the seat belts. The recall repairs were performed, but afterwards the seat belt would not latch for approximately one month. At 7,000 miles, the vehicle speed control became inoperable. At 22,000 miles, the driver's side passenger door latch cracked at the base. As a result, the contact had to roll down the window and open the door from the rear in order to exit the vehicle. The vehicle began pulling to the left while driving between 40-70 mph. An independent mechanic stated that the tire had a hole in it and would be patched. Also, the vehicle needed an alignment and the contact was informed to take it back to the dealer to have the specifications checked when the alignment did not correct the issue. The failure mileage was 7,000 and current mileage was 23,450.

The contact owns a 2006 Suzuki Forenza. The contact stated there are many defects with the vehicle. The vehicle was taken to the dealer where they stated all the failures are not cover under warranty and she has to pay out of pocket for all the repairs. The defective parts are the front and rear struts, throttle body, door handle and transmission range censor. The manufacturer was not contacted. The dealer informed her they contacted the manufacturer and was told the vehicle was not covered under the warranty and she would have to pay for all repairs. The failure mileage was 56,000.

The contact owns a 2005 Suzuki Forenza. While driving 5 mph before stopping at a traffic light with her foot on the brake pedal, the vehicle accelerated on its own. The contacts foot remained on the brake pedal when the vehicle changed gears and slowed down. The failure has occurred seven times. The dealer was contacted and stated that they have never had any complaints on her year, make, and model vehicle. No repairs were made to the vehicle. The failure mileage was 6000. The current mileage was 16125. Updated 3/4/2010 updated 06/18/10.

The contact owns a 2006 Suzuki Forenza. The contact stated that the vehicle accelerates or jerks forward when he depresses the brake pedal to stop the vehicle. There were no warning lights present. She must shift into park in order to successfully stop the vehicle. When shifting gears, she hears a thumping sound. The vehicle was taken to the dealer and they stated that nothing was wrong, however, they advised her to apply more pressure to the brakes. The second time she took the vehicle to the dealer they acknowledged the failure. The speed was unknown. The current mileage was 8,500 and failure mileage was 500. Updated 12-12-07.

On April 21, 2006 after coming off i95 interstate coming to a stop my vehicle accelerated, resulting in hitting a parked car. I took the vehicle to the dealer, who "found nothing wrong. " the vehicle continued to have the same performance, accelerating when attempting to slow down after over 45 mph non stop, on 3/27/07 I had the vehicle in for parking lights not shutting off, and spoke with a technician who immediately know the problem.

The contact stated the engine revved, it was racing, and the rpm gauge ran higher than normal. The vehicle will hesitate at any speed. There will be a loss of power, and the vehicle jerked when power went back into the vehicle. There was no prior warning. This happened every time when driving the vehicle. He took the vehicle to the dealer. They said the ecm had to be reflashed. Dealer did the work. The vehicle is still having the same problem since then. Engine check liht came on, and vehicle seemed to run higher when cold outside.
