I was driving home and the car suddenly went into neutral gear luckily I was able to pull over without being hit in the back, this had now happened 3 times since the first incident. I am afraid to drive my car now. Also when it shifts into neutral gear, on the dash where it shows the gears the D sign is all scrambled.

On numerous occasions the transmission would slip gears, the vehicle jumps and the check engine light goes on. An independent mechanic told me it was the transmission range sensor that was defective and needed to be replaced. This is a seriously dangerous issue because it happens mid drive. Apparently its my transmission range sensor and it has happened to a lot of people. I have done research on this issue with this particular vehicle and have found that this issue is very wide spread. I feel that no matter how well the maintenance on this vehicle is kept up, this issue is destined to become a problem and a safety issue. Because this sensor glitch causes the vehicle to suddenly switch gears and slowdown without warning or brake lights, there is a high possibility for accidents. I believe there should be a recall for this to be fixed. Suzuki motor Corp is grossly negligent for naot making a voluntary recall on this inherently defective part. It is the duty and responsibility of ntsb to compell the manufacturer to issue a recall on these 2006 Forenza vehicles.

Forenza 4-cyl

  • 106,300 miles


My 06 Forenza would not shift into drive and the check engine light would come on then it would get better and the check engine light would turn off. Then I started getting the periodic clunk and scrambled display, usually while in a parking lot or when just starting a trip and driving slow. I finally took it to advance auto and they told me it was the transmission sensor. They sent me to the dealer who made me take the car back home because the check engine light had turned back off and they couldn't read the codes. It's still not fixed because when the check engine light comes on it never at the shop. I have researched online and find that a lot of consumers are having the exact same problem with this car. I think Suzuki should do a recall for this problem because it's not a random problem but seems to be a standard problem.

Been having problems with the check engine light being on/of for as long as I have had the car the gears started slipping or staying 3rd, 2nd or R all the time. Took it in to try and have it looked at or check the transmission for fluids since it has a sealed transmission. First thing that came up was - I had no warranty, and prices for them to check to see why the check engine light is on before they can do anything. Now the airbag warning light stays on as well as the check engine light. And the key will not come put of the ignition. Very unsafe. What can a broke unemployed person do?.

I purchased a used 2006 Suzuki Forenza in California. Biggest mistake of my life. I have had nothing but problems since I brought the vehicle. Two weeks after my purchase the engine light came on. I was visiting family in las vegas who helped me find a near by dealer. After the diagnostic they advised me the valve cover was sealed improperly. Now I just got the car 2wks prior so I called the used dealer I brought he car from and let them know what was going on. Not to mention the passenger door handle broke off. I see I am not the only one with door handle complaints. The dealer in las vegas fixed the leaking valve cover and replaced one spark plug as oil leaked into it. This was fixed under the warranty. A month later the vehicle started to stall and then accelerate by itself. The engine light came back on so I took it to a Suzuki dealer in van nuys, ca. The service manager advised me after the diagnostic it was the battery. I had the battery replaced and paid a diagnostic fee a total of $275. A few months after that the engine light was back on. While on my way to work the car stopped accelerating almost causing a vehicle to hit me. I took it back to the same dealer in van nuys who advised me the throttle was the issue. They replaced the throttle and the same issue is happening. They now claim it's the main engine wiring harness. I called american Suzuki to see if the "engine wiring harness" is covered under warranty. The power train does not cover the wiring harness. The dealer is asking for $1600 to replace it or $489 to repair the wires. I have only had it for 7mos. The dealer also gave a lengthy list of recommended services totaling $2541. I declined all recommended services and currently do not have a working vehicle. I believe the issues with this vehicle are pre-existing and the dealer I brought it from knew about it. I plan to return this car.

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. "

Forenza 4-cyl

  • 656,000 miles
Yes my cars gears when I drive would go in different gears and I almost got hit. I use this car for taking my kids to school and I love my kids very much. I contacted the dealer ship and they acted like they did not care about this problem and I told them that alot of people have complained.these cars are dangerous and a safety hazard and should not be allowed to be sold or be allowed on the road. And if something happens to people and their families then Suzuki and anyone else who allows Suzuki to sell these cars should be held responsible if something happens to someone. I will retaliate if something happens to my children. I and all the other people would appreciate if you either stop them from selling these cars or have them recalled. Or make them go to the junk yard. Thank you
