Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Driving along when all of a sudden the engine just cut off, I still had electrical power, all systems were still working. I got to side of road turned everything off. I then tried starting the engine, after about three or four times the engine would start. I then drove the car trying to get home, when I would come to a stop light the engine would stall again. This could cause a very bad accident if on an interstate at high speed.

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!

Forenza 4-cyl

  • 67,000 miles
I recently lost my car which was a '07 Suzuki Forenza to what has been described as a mechanical car fire brought on by some sort of mechanical failure. I believe this was a culmination of a series of failures over time despite whatever action I took to avoid it. Initially I encountered intense flickering with my headlamps. Headlights would stay on even after removing the key from the ignition. I believe that the consistence of this occurrence, has caused my vehicle's battery to fail. I ultimately had to have the battery replaced. I would also have a toxic smell come through the ventilation system from time to time. It smelled like something burning and melting. However, I was never able to determine what it was. This was going on intermittently for quite sometime. Then eventually my car was lost to the mechanical car failure fire. I was fortunate to get out of the vehicle with only minor injuries such as burns and smoke inhalation.

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.

Was driving and transmission range sensor went bad and car jumped out of gear no warning. Traffic behind almost collided. My 4 year old was in back seat. Very scary. Called Suzuki and they said this is an extremely common problem considering my make, model, mileage. So why am I, a single disabled mother, responsible for getting a well known, unsafe manufacturer issue repaired..... I can't afford this and from what I was told most people with similar issue had this problem not only once but few months after getting repair done. This is extremely unsafe! car shifting and stalling while at full speed! me and my son could have been seriously hurt! planning to call Suzuki customer relations to see if they can fix issue because it is not fair that I have to come up with way to repair such a dangerous problem so many Suzuki owners have experienced.

I was on the highway when out of no where my car jerked and slowed speed. I almost got rear ended. I then tried to accelerate and it drug. Instead of catching back up to speed it took a minute to reach the speed of what was posted. And since then its been very hard to drive. I took it to shop they said I need a new transmission range 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. For a reference the Suzuki dealer sales the transmission range sensor for $38.99 and the mechanic charged $25 labor.

Why isn't any thing being done about this problem with the transmission range sensor!!!!! Suzuki needs to acknowledge that this a serious problem. I initially just got on here to file a complaint and started reading there are alot of people with this same issue. Please take some kinda of responsibility for this issue. I have had to fix my transmission range sensor more than once. This week will make the 2nd time in a year! I was driving in a 35 mile zone and my car would not even go the speed limit a car alot rammed me from behind. It slows in the middle of traffic and sometimes wont go backwards. Something needs to be done. It seems clear that there is an active issue with the transmission range sensor in Suzuki Forenzas.

Forenza 4-cyl

  • 70,000 miles
I could really use some assistance. I have a 2007 Forenza and yesterday as I was putting the car into reverse, it made a loud clunking noise. The gear selector display on the dash seemed to go haywire displaying all the letters (D, R, N, etc) with a diagonal line through it. It then went back to normal, then the "check engine" light came on. They hooked up the diagnostic computer and it came up with codes PO700 and PO705, which varies in wording but seems like it's the transmission range sensor.I have read that many other people have had the same problem. This is a problem that Suzuki should take care of a sensor cost to those who bought their cars.

  • 49,000 miles
My check engine light came on to find that my transmission switch had gone bad causing it not to shift correctly....thinking no big deal, I took it to my mechanic. He said these transmissions were known as throw away transmissions. I came home and googled my problem to find numerous lower mileage Suzuki Forenzas with the same issue, some almost causing accidents. Please consider a mandatory recall on this part.

Forenza 4-cyl

  • 85,000 miles
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!
