A malfunction occurs when I attempt to shift gears from park to any other. 1. it makes a loud, deep sound, similar to "thunk-thunk" and if I don't have my foot on the brake hard enough, the car lurches. 2. the dashboard signal for pdrn etc randomly changes to a weird symbol that is not any letter in the american alphabet. 3. it makes a revving sound which should indicate a higher velocity when in fact it is at a lower velocity. 4. it will not accelerate properly. When entering a high frequency road or highway, I have to floor the gas pedal to go normal speed then maintain it. 5. it shifts out of drive into neutral while I am driving and independently of my activity, thankfully approximately only about once every month. 6. the check engine light is always on. 7. the mechanic said it was related to the transmission but was called a range something or other. 8. I notice these problems more in stop-and-go city traffic than on long uninterrupted distances. 9. I consider these random car behaviour problems unstable and unsafe. 10. to any driver new to handling/driving my car, I would have to explain its quirks for them to drive and not have a tragic vehicular accident involving the improper response of my car to normal use. 11. the warranty ran out long ago. It was only for three years. The problems started occurring after the warranty expired, of course. 12. it will cost me about $200 to get the range whatchamacallit fixed, $200 of which I believe Suzuki should pay. Unrelated problem, sometimes the seatbelt buckle unclicks itself.

I have had so many problems with this car!! it started out as I was shift into or past reverse. Now it shifts on it's own while driving, while pulling into traffic, while at stoplights/stop signs. You will be driving and it will jerk and put itself into park but still go. It's like driving a stick shift without letting off the clutch. This is a very dangerous vehicle to drive. You don't know when it's going to act up. I have my daughter in the car and wait until it's absolutely clear to pull out due to this. Tonight (10/13/11) I was driving, hit a bump in the road that I've driven over a million times and simultaneously, my brake light and my battery light came on. I drove to my destination with my lights dimming slowly and pulled into the spot and the car died. I spoke to the local Suzuki dealership and asked the service tech is he gets alot of issues with this sensor and he says "the numbers are higher than they should be for this car. "

My 2006 Suzuki Forenza looses acceleration while driving; simply put the gas pedal doesn't work. While driving on the highway at speed, and with out cruise control, I will let up on the accelerator and when the accelerator is pressed in again I have no acceleration. This type of incident has occurred numerous times on the highway; even while attempting to pass a vehicle. This is very concerning because I feel I might be run over by a vehicle behind me if I loose acceleration. The vehicle has a tendency to lunge forward while stopped due to this malfunction of the throttle body. The car is not safe to drive anywhere with the possibility that it will not accelerate properly or lunge forward into a car at a stop light. I have contacted Suzuki and they tell me it is not a malfunction and will not honor their 7yr; 70,000 mile warranty. I have had several trips to the mechanic to try to fix the problem; and we have worked our way through everything down to the very expensive throttle body. I went to a dealership and all they did was clear the codes; 10 miles down the road the car started doing the same thing all over again. I would like this fixed before there is a sever accident because I'm driving a defective vehicle.
