1 Check Engine Light On problem

Failure Date: 03/15/2016

I have had the transmission range sensor replaced on my 2008 Suzuki Forenza twice already and it has malfunctioned again. When it malfunctions, my car jerks heavily when changing gears, and it is an automatic engine. The rpms will not exceed 3000, the check engine light comes on, and "hold" flashes in the dash. The car accelerates very slowly shudders above 50 mph. The speedometer has dropped to zero while I have been driving on the highway, so I cannot tell how fast I am going.

2 Check Engine Light On problem

Failure Date: 11/15/2014

The check engine light came on when putting my car into reverse. The car would jump whenever putting it in reverse or drive. I had a scanner put on it and the codes came out to be the transmission range sensor. The check enging light will continue to go on and off depending on how much I drive it. I am being told this is not under the power train warranty. This needs to be as it is affecting the power train.

4 Check Engine Light On problem

Failure Date: 07/01/2013

Every time I change gears, my car thunks under the hood and my check engine light is continuously on. A machine was hooked up to my car and it reads that there is a bad transmission range sensor. I've done my research, and notice an unbelievable amount of complaints due to the same issue/part. When this happens in my vehicle, it drives very poorly and feels like it cannot shift into the correct gear. This is unsafe.

8 Check Engine Light On problem

Failure Date: 10/09/2012

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.

10 Check Engine Light On problem

Failure Date: 07/10/2012

I am thinking our transmission range sensor went out on our 2008 Suzuki Forenza with over 70,000 miles. Car check engine light was on for a few days, then turned off about 3 days ago, stopped at drug store, when I turned on the car, the check engine light was back on, put car in reverse and clunk, while the display where the r for reverse would have been was scrambled, car still reversed. Clunked into drive, and wouldn't switch out of 1st gear.

11 Check Engine Light On problem

Failure Date: 12/14/2011

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.

12 Check Engine Light On problem

Failure Date: 09/01/2010

The contact owns a 2008 Suzuki Forenza. The contact stated that when shifting into drive with the brakes depressed, the engine would shift abnormally, causing the check engine warning light to illuminate. Neither the dealer nor manufacturer was notified of the failure. The vehicle was taken to a private mechanic who replaced the brake pads however, the failure persisted. The current mileage was 80,000 and the failure mileage was 73,000.

13 Check Engine Light On problem

Failure Date: 07/30/2010

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.
