Vehicle purchased new in 2006. Under 16,000 miles one owner. Hard shifted out of park or reverse. Lost power when in drive with normal RPM's~ diagnosed as faulty transmission range sensor by independent repair shop. Replacement part also faulty. Please note mechanic used term "faulty". Extreme safety issue. I expect suzuki motor company to issue a safety recall with parts that are designed not to fail at such low mileage.

Transmission range sensor is failing and caused a loss of power almost causing a major accident. This is a common problem with this model year, and needs to be investigated for a safety recall.

I was driving down the road like normal and came up to a stop light. As I was slowing down it downshifted hard and when I tried to accelerate from the stop light it took more gas than normal to pull away. I then noticed that my check engine light was on. I took my car to an auto store the next day to read the codes. It gave the codes po700 and po734. When this happened I had a loss of power and acceleration and was unable to go normal highway speeds. Also when shifting from park to reverse or from neutral to drive it shifts hard and kind of clunks into gear. The next day I tried again and it was shifting just fine, but still had the check engine light. Later that day the same problems from the previous day returned. When the second incident occurred I was trying to make it back home through a heavy snow storm. If this problem had caused me to stop on the side of the road I could have been hit due to the zero visibility. I have seen many complaints about this same problem and trouble codes and I believe something should be done about this.

I have a 2006 suzuki forenza. I bought it new, off the lot in york pa from a suzuki dealer. About 3 months after my purchase, the car began bucking and when I took it to the dealer, they could not find anything wrong. Over the last 3 years, the car has continued to buck on cold mornings and after sitting for more than 24 hours. The car now has approximately 59,000 miles on it. Then, last week, as I was driving, the car suddenly lost power. The engine light came on and the "d" (for drive) began flashing at me but it had a line through it, making it look more like an "8". I had to floor the gas pedal to get the car to accelerate. I immediately took it to a local dealer (not a suzuki dealer). They found that the transmission selector switch was bad. Over the past several days, I have read of other peoples' stories, very similar to mine. Had this problem happened on the highway, I could have been in a serious or even fatal accident. I am now going to have to put out a great deal of money to get this problem corrected.

Tl*the contact owns a 2006 suzuki forenza. The contact noticed that the tranmission shifted eratically since purchasing it in january 2008. He first. While driving on approximately 55-60 MPH, the vehicle slowed down, sped up, lunged forward and shifted into gear without warning. There was also a roaring noise on the front end of the vehicle, a clicking sound near the dashboard, and every light turned off except the check engine light. The radio and air conditioner intermittently turned off and after five minutes, they both began operating normally. The dealer was unable to duplicate the failure; however, the manufacturer would not authorize the dealer to inspect or repair the vehicle. On one occasion, the windows would not close causing rain to enter inside of the vehicle, 20 minutes later he was able to close the windows; however, the vehicle began to lose power with the motor on and fully functional. The service advisor at the dealership stated that the acceleration pedal sensor could have caused the failure. The manufacturer once again authorized the dealer to disconnect the battery. The current mileage was approximately 23,800 and the failure mileage was approximately 13,000.
