My 2008 Suzuki forenza loses power hesitates and regains power slowly I have had it into the dealer ship and they said it was fixed The car had to be towed back to the dealer ship last week for the same thing and they said it was a spark plug I am still having this problem my car is still under the power train warranty how can I get this repaired

I also have a 2008 Forenza. It is currently at the dealership because the transmission failed. I took it to the dealership and asked them to look into it when I got an oil change, they said they found nothing. Two days later, the check engine light was on and the car was severly jerking like it could not catch the correct gear. At first they said it was a sensor, and fixed that. I picked the car up, drove 1 mile, and it started jerking again - needless to say, I went back. They told me it could be the transmission module, but if not, they would have to replace the entire transmission. My advise is to be persistant with the dealership to find your problem or they will continue to pacify you and brush you off.

I also have a 2008 Forenza 62,900 miles and my car is doing the same thing...The problem with my car is the Throttle Pedal Position Sensor (TPS OBDII Code P2135) attached to the throttle body. You can not just replace the sensor because it is sealed to the throttle body. However, if your car has less than 80,000 miles your engine, it components and labor is still covered under the engine warranty. Have them check the codes...I bet one of them is the TPS code. They will have to replace the throttle body (a $400 part). Give them your year, mileage and VIN...Good Luck! Mine is getting replaced tomorrow.
