I've had so many problems with this vehicle. Spent over $4000 in repairs in the last 6 months. The first problem I had was while driving on the highway the reduced engine power light and traction system light would come on and the vehicle would just decelerate and wouldn't go over 15mph. I had it repaired once and was told it was the wiring harness and then 2 months later the same thing happened again had it repaired and was told it was the wiring harness and computer that needed replaced. And now I'm having a similar issue but this time the service engine soon light is flashing but the car doesn't want to accelerate and takes several seconds to even get up to 35 MPH. I had this repaired once and was told it was a wiring/fuse issue and that the car was only running on 3 cylinders and literally 2 days after the repair it started happening again. This is ridiculous. My mechanic even told me I should just get rid of the vehicle because it obviously has major wiring issues. It only has 130,000 miles.

For the third time in about two weeks, my car had the "reduced engine power" light pop up and it just slowly came to a stop while driving on the highway. The second time it happened I also lost power steering. Each time I managed to pull over to the side of the road and I jump started the car. Another reported incident on here said that they just waited a few minutes to restart it, but I have a portable device that allowed me to jump start my car immediately. I went to autozone to test the alternator and the battery and both were fine. This may or may not be unrelated, but whenever I start my car I usually have to press the gas pedal a little bit or the car won't start properly.

Intermittent loss of power, loss of ABS brakes and loss of awd. When you apply pressure to the gas pedal (accelerator) if you depress the pedal for what feels like over a 1/2 inch you lose power and the rpms go sky high and you can hear it trying to rev up. To get going you have to release the gas and press lightly. I loss power, esp. Going uphill since it needs more to go, but you can't give it more gas else it won't go. I and my fianc were almost hit in an intersection because of this loss of power. You can gain speed, but very slowly and anytime you depress the gas pedal further it again fails. Replaced three wheel bearings, all brakes, two calipers and the throttle position sensor. Nothing shows on the readout except for the front bearings aren't reading right, but they're brand new and have been re-checked for defect. Still that hasn't fixed the issue. Upon problem has actually been occurring for almost two months now.

At 65 miles per hour on a highway in rich hour traffic my vehicle stalls out and displays 2 lights 1."reduced engine power" "service traction control system" or something to that effect. The car will not start for 3-5 minutes. Then restarts and continues to do the same thing another 5-7 times before I was able to get to a safe location. When hooked up to a code reader the code that displayed was co240 ABS powertrain control module.. This is extremely dangerous.

The problem happened while driving, the engine shut off without warning. The 'reduced power engine' light came on. I coasted to side of road to let folks get by and sat and waited for about 5 minutes and tried the key and the engine started. No codes stored. No check engine light. I still had power windows, radio, lights and horn. The silent engine happens at least twice every other day. Noone has a sense of what is happening and the safety issue is when I am on the interstate and the engine suddenly dies out. I am a little worried since this is the only car I have to drive to get me back and forth to work.
