I was stopped at a red light and started to drive the car when the light turned green but my car did not want to go forward, my car pulled. I had to step on the accelerator with more pressure for it to go forward. I finally got to a safe area and turned the car off. I left it off for about three minutes then proceeded to turn it on and drove off, I notice my check engine light was on at that point, and drove to my mothers home nearby where my brother who is an auto tech scanned my car and the transmission range sensor code came up. Help is there a recall on this?

This Suzuki needs to be recalled altogether! no one should still be driving these. Not only can the headlights or brake light sensor switches go bad and just stop working, they overheat, drain the battery, overwork the alternator, which then needs to be replaced, the fall displays every gear all at once even while in drive and displaying a speed the vehicle is traveling. The door handles brake off, so you can not escape the death trap. They have blown head gasket, many small oil leaks, tire pressure gage problems, tires/wheels won't align, this balds the tire lop sided so tire blow outs occur more frequently. Half the tone it won't even go, now or won't start at all. Many more issues with this vehicle, buyer beware, do not buy these cars!

When operating in drive position the vehicle went into neutral with loss of traction, drive power could only be restored by selecting drive position 3. there were several subsequent occurrences of the problem one of which nearly resulted in a rear end collision. A transmission repair shop diagnosed a neutral safety / transmission position switch failure. This appears to be a repeating complaint theme with this vehicle model. The occurrence is unnerving and could result in severe (potentially fatal) consequences.

My daughter (16) was on the highway and the service road when out of no where the car started jerking and slowed speed. She then tried to accelerate and it drug. Instead of catching back up to speed it took a minute to reach the speed. And since then its been very hard to drive. We took it to shop they said I need a new transmission range sensor a brake light switch and an input and output system and a speed sensor. They also said this is a very common issue with Suzuki Forenza. But its very dangerous I do feel that this should qualify for a recall before someone gets killed. Is anyone only listen to these reports at all? [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I keep having to stick a key in my shift lock just to get the car out of park and has been occurring for a while now. The part you put the seat belt into when you put it on keeps sticking down so you can't wear a seat belt sometimes and I have had to replace my transmission range sensor about every 3 months since I have had the car which is ridiculous.

Coming home from work, my transmission suddenly shifted into 3rd gear as well as my speedometer started bouncing. During this episode the cruise control began to drop out. A while later, about 2 miles, the engine lost power and I had to pull off the free way and got towed home. I googled my car situation and found that there have been numerous events as mine. Has Suzuki addressed this issue and if so, what is the fix?

Before taking my kids to school, I put my car in reverse to back out of my parking space, as soon as I switched it from reverse to drive, my car would not move. I noticed that on the digital screen that the "D" had a slash mark as if to say "no driving", and the check engine light came on. I put the car in park and turned it off. I restarted it to see if maybe it was a glitch in the system. This time, I went from park to drive and the slash mark was still on drive, however I was able to drive the car very slowly.. it wouldn't go over 5mph. I reversed and parked back into my parking space. Once this happened, I decided to do some research. Turns out, it is the transmission range sensor, and a lot of owners are having the same issue. The next day, I decided to attempt to drive it again.. because we all know these cars have a mind of their own and seem to decide to go bad one day and act completely normal the next! I started the car and the check engine light was on, but seemed to drive fine. I drove it to have it tested at the auto store. The test confirmed that it was the transmission range sensor. I then stopped at a store on my way home. I was in the store less than 5 minutes, came out to my car, and it would not start! I thought the battery had ironically died. My brother in law came to jump it, but had no success. I turn the key all the way over, and the service lights come on, but it wont even try to turn over.. its almost as if the car has nothing under the hood... crazy that it wont even attempt to start. My brother in law says it may be the starter, but something tells me this all has something to do with the transmission range sensor. Please put this part on recall! I've seen enough complaints from owners that I cant believe there hasn't been one yet. Enough is enough! recall the transmission range sensor! this is dangerous!!!!

Put my car in R (reverse) on a level driveway and it made a clunking sound as if it were being forced. The dash gave a signal instead of an R for reverse, a square with a line through it. As I put it into D (drive) it dragged to accelerate. The check engine lamp came on and the local mechanic said his computer read transmission range sensor. He said the trs and the catalytic converter need to be changed. The car needs a couple of motor mounts. This will easily cost me over $800 including labor. I just finished having the transmission coils and wires replaced ($350) having just purchased this vehicle (used) from a private party; my concerns are high regarding safety and costs for repairs. What of a recall concerning the transmission range sensor? please help!!

I am the owner of a 2007 Suzuki Forenza. As I was getting ready to travel across a bridge when the car appear to change gears even though the shift was in drive. I immediately changed the shift to 3rd gear and slowly made my way across the bridge. Had the car inspected, I went with the mechanic on test drive and it happened again. They diagnosed the problem to be the manual level position shift sensor. Car worked fine until about a month ago, it did the same thing. Now I drive very cautiously.

I had defective plastic door knobs that broke and replaced with the same type door knob by the dealer and charged me labor. Replaced strut mounts within the last 9 months I have replaced: Transmission, water pump, the valve cover gasket 4 times, the valve cover, the radiator, the timing belt, the ac compressor, front axles, wheel bearings, lower intake manifold hose, and it is still leaking antifreeze. The car seem to be very hot and the key is very very hot in the ignition. I also need to replace the fuel assembly........ I definitely would like to be included in a class action lawsuit or I will do my own. This is not fair to the consumer to pay all this money into keeping this car repaired. I've invested more into this car than what it is worth. Please advise.

The car indicates that it is no longer in drive. Even though on the shifter it says it is still in drive. Also when driving down the road the car will come out of drive. To fix the problem you must pull the car into third gear, wait a few minutes then put it back into drive.

Forenza 4-cyl

  • 14,000 miles
I am the owner of a 2007 Suzuki Forenza with a recurring transmission range sensor failure. Out of the 7 years I have owned the vehicle, I have had to replace the transmission range sensor every 14 months like clockwork. No other dealer other than an authorized Suzuki dealer is able to replace the range sensor. The failure causes the vehicle to abruptly engage into neutral without warning. On several occasions, I have attempted to accelerate from a complete stop and the vehicle would drag or would not accelerate over 10 mph. On one instance, I was rear-ended due to the failure but luckily no one was injured. I believe that Suzuki knows there is an issue with the sensor, which is a major problem for an such an important component on the vehicle. This could cost someone their life! please do something or at least have Suzuki stop replacing the failure part with a defective part that they know is going to fail within 14 months. The failure mileage was 14,000 and the current mileage was 92,000.

After being parked for a while the car jerks when I shift to reverse as well as makes some kind of clunking sound. Afterward, when I shift to drive, there is a marked delay prior to acceleration. This also happens whenever I come to a complete stop at traffic lights, stop signs etc. I'm wondering if this is the transmission sensor again which I had to replace in 2011 @ 30K miles because my car would stall while in operation. This transmission sensor issue is way too common in these cars for Suzuki to not have issued any kind of statement or provided any restitution yet. I'm dreading having to pay another $200+ for repairs. This is a dangerous defect and they shouldn't wait like GM to deal with it. These vehicles should be recalled.
