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.

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.

My family and I were going down the road and there was a weird noise and the engine started to rev up and the speedometer was going down to 30 miles an hour, at the same time the RPM"S were going higher. I pulled to the side of the road because the shift gage on the instrument panel was flashing weird. It had a D with a line thru it. We had to shift it manually from 1st gear up to drive. It was scary since there was a truck with a trailer behind me coming up fast. It has done this to us twice in the last two weeks.I have seen that there are other people having the same problem or similar. Something should be done. When we have a warranty we still shouldn't have to pay a deductible for some problem with this brand car" power train and speed control sensors. Going out and needing to be replaced.

While sitting at a stop sign, I decided I was a little to far into the road. I shifted into reverse and noticed it shifted really hard. I put it into drive and pulled out onto the road - again it shifted hard. When trying to speed up, the car wouldn't shift out of 1st gear, the check engine light came on and I couldn't speed up. I've been told it is a bad transmission range sensor.

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.

Owner states that the check engine light comes on and loses power..car will go from drive to a different gear. This happened on numerous occasions (when at red lights..going uphill ( which is dangerous if there is a vehicle behind you) and regular driving. Took vehicle to transmission shop 6 times and after spending over $750 on range sensor and computer board problems...still having the same issues with check engine light..loss of power and gear slips.

My transmission range sensor has been replaced twice, both within a 12 months time frame. Both times my car jerks at low and high speeds and my engine light is invoked. The second time the dealership replaced my transmission range sensor...the very same week my vehicle is still experiencing the same exact issues, inclusive of my engine light coming on and staying on for 3 days. Upon return, the dealership says my jerking, hard gear shifting and on board engine light is being caused due to an engine skipping issue, which is "possibly" due to the electronic control module not communicating with the transmission control module. I'll have to pay the dealership $210 to see if the connector between the ECM and the tcm is bad, and if its not bad, I still pay the $210, but then they'll tell me what the next possible step would be?? I feel I'm in a no win situation, it sounds like, just keep writing checks. My issue sounds the same as the countless others that have been documented, my issue should be covered since Suzuki is more than aware that these are known issues.

Forenza 4-cyl

  • 55,000 miles
I noticed after purchasing the car with 40,000 miles on it after owing the car for 5 months I put the car it reverse and it made a loud clunk when it was shifting in gear and repeated the same noise when putting the car in drive. After putting the car in drive the car would not accelerate like it was not shifting into gear. The issue has persisted and I had my brother, a licensed mechanic look at the car and he determined that it is a sensor in the transmission causing the problem. The car will not shift into gear until it reaches 45mph until it shifts into gear the rpms will jump like the car is straining to get into gear. After researching the problem I have learned that a lot of Suzuki owners have this same problem.

Forenza 4-cyl

  • 95,000 miles
In less than 2 months, I've had to replace several parts of my car that I don't believe is part of regular service maintenance. Thermostat, coolant hose, spark plugs (twice in a year), brake lights and headlight bulbs (replaced twice in a year), transmission control module and motor mounts because of the tcm that made my car jerk all the time whenever I accelerate. Either at a traffic light or on the freeway, my car hesitates to accelerate and jerks every time I shift gears. Now, possibly the transmission range sensor needs to be replaced (I am currently in the process with this one). I'm afraid in the next few months, I'll be spending more on car repairs than the car is worth and it's only a 2008!

Forenza 4-cyl

  • 50,782 miles
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.

  • 30,000 miles
The contact owns a 2008 Suzuki Forenza. The contact stated that while driving approximately 10 mph, the brake pedal was depressed and the vehicle suddenly accelerated. The vehicle was then shifted into park in order to stop it and the check engine light illuminated on the instrument panel. The vehicle was taken to an authorized dealer for diagnostics, where the technician stated that there was a failure with the transmission. The contact was unaware of the repairs that were performed. After the repairs, the failure occurred a second time. While driving approximately 5 mph and attempting to park, the engine revved up and the vehicle suddenly accelerated while the brake pedal was depressed. As a result, the vehicle crashed into a glass window. The vehicle came to a stop when the contact placed the gear shifter into park. There were no injuries. The police reported to the scene and a report was filed. The vehicle sustained damage to the front end and under carriage. The vehicle was taken to an auto body shop for an estimate of the repairs. The vehicle was not repaired. The approximate failure mileage was 30,000. Updated 10/04/11
