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!

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.

The contact owns a 2006 Suzuki Forenza. While parked, the contact noticed that the lights on the instrument panel would not illuminate. The contact was pulled over by a police officer who informed her that the rear passenger side tail light was not functioning. The contact replaced the fuse twice but the failure continued.

Driving down interstate had smell coming from the dash like melting wires. Dash high/low beams stopped working, luckily daytime running worked but not good enough to see well at night periodically they will come back on for a few then cut back off. Most often they do not come back on at all and doesn't stay on long..afraid of fire or if working going out while driving and wrecking with my kids in the car. We purchased this car last year from a used car dealership and it was fixed under the recall or 07 in Jan 2008, called dealerships and Suzuki and they are telling me even though there is a new recall out for the same thing.. for 2004-2006 Forenzas manufactured between the dates of Sept 2003 and March 2006 that my car that was manufactured 11/2005 doesn't fall under the recall? just need to know what to do since its obviously a manufacturer defect. Or if maybe some information was crossed and hopefully ours can be fixed under the recall.

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 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.

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).

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. "

Two years and 29K miles after I drove my brand Forenza off the lot I was on the highway at the beginning of a road trip when my sensor first went out. I had to turn around, take it to the dealership an get it replace. Now I am at almost 90K running into the same issue and will have to replace the sensor again at a cost of abou $250. Quite a few highway miles, not alot of city miles not confident in making Suzuki a new car choice again.

Forenza 4-cyl

  • 38,000 miles
My 2006 Suzuki Forenza looses acceleration while driving; simply put the gas pedal doesn't work. While driving on the highway at speed, and with out cruise control, I will let up on the accelerator and when the accelerator is pressed in again I have no acceleration. This type of incident has occurred numerous times on the highway; even while attempting to pass a vehicle. This is very concerning because I feel I might be run over by a vehicle behind me if I loose acceleration. The vehicle has a tendency to lunge forward while stopped due to this malfunction of the throttle body. The car is not safe to drive anywhere with the possibility that it will not accelerate properly or lunge forward into a car at a stop light. I have contacted Suzuki and they tell me it is not a malfunction and will not honor their 7yr; 70,000 mile warranty. I have had several trips to the mechanic to try to fix the problem; and we have worked our way through everything down to the very expensive throttle body. I went to a dealership and all they did was clear the codes; 10 miles down the road the car started doing the same thing all over again. I would like this fixed before there is a sever accident because I'm driving a defective vehicle.

I have a 2006 Suzuki Forenza, and it also is having all the problems everyone else is talking about. My car has about 47,000 miles. It started with the engine light coming on and off at random times and then my car would barely go when I pressed the gas pedal. I still can push the pedal all the way to the floor and it will go very slow and my car engine sounds soooo loud. Recently I put my car in reverse and then it jerked back and when I put it K into drive it jerked forward and didn't want to go even tho it was in drive, then on the odometer it had a box with a line going through it and a line going across as it was flashing. Sometime I will not have problems with my car and then I will do it for days. How do you fix this? this car is dangerous and should be recalled!! I have 2 toddlers that drive in my car with me everyday and this is very unacceptable!! will be getting a new car as soon as I can.

Air conditioner will not maintain forced air after two hours of use on warm or hot days. Must turn off conditioned air for about an hour to let the system rest. This is very annoying while traveling long distances with children in the back seats.

Range sensor is defective. This is a known latent failure that is not covered after 36,000 miles. The dealership informed me that the part, although part of the main engine, is a known failure and that the replacement was a $55 part. The main dealership in huntsville has replaced over 1000 range sensors when my car was repaired in October.

Forenza 4-cyl

I own a 2006 Suzuki Forenza and have had numerous problems with this car. Since purchasing new in 2006, I have had the gas gauge, gas tank, radio, center console, front door handles & catalytic converter replaced. The factory tires went bad within a year, and because it is an odd tire size cost over $400 to replace. Currently the check engine light is on stating there is a problem with the catalytic converter which was just replaced about 3 months ago. I left the car overnight at the dealer & got a rental car (which cost $75) and the dealer and Suzuki tech support can not figure out why the catalytic converter error continues to show up. The power steering light is also on & I was told that it requires a sensor - not covered by warranty - that will cost over $300. I have had a problem with the engine jerking and slipping gears on acceleration. It would also stick in neutral or not change gears and hesitate to the point of moving very slowly. I was told this was an oxygen sensor which cost me over $300 to replace. I have had this problem once since. The struts - front and back - also need to be replaced which is a $1200 repair because they are leaking. Currently both front door handles are broken causing me to have to open the windows to open the doors. I have had them replaced once before under recall, but now it will cost over $200 a piece to replace. I didn't even know there was a light to indicate that the daytime running lights were working until it just appeared one day. The daytime running lights indicator won't stay on - it comes on, then goes back off. I think Suzuki needs to make good on these cars because there are so many problems.

The contact owns a 2006 Suzuki Forenza. The contact stated that he experienced several electrical failures with the windows opening independently, failed headlights, flickering instrument panel lights and a failed battery. The vehicle was taken to a local repair facility where it was diagnosed. The mechanic advised the contact that the electrical failures caused the battery to fail. The dealer was contacted and advised the contact that the warranty was expired therefore; he would be responsible for the diagnosis and repair costs. The contact stated that the vehicle was taken to the dealer previously for the failures and the dealer cleared the computer codes but the failures persisted. The failure mileage was 15,000 and the current mileage was 66,401. Updated 01/11/2011
