2007 Ion · 170,000 miles · Nov 2019 · crash

While traveling between 70-75mph on I-35 southbound between 2nd st. Merge and 15th street exit in edmond OK, we went to change lanes (middle lane to right lane) and there was a sudden boom, the car lost control, began to spin out of control (numerous slides and 2-360 deg turns and being flung in a backwards motion). As we attempted to get to the side of the road, our car began to spin out of control - we spun into a 360 degree turn, car caught fire as the oil was dumped from my car and sprayed all along the underneath of my car and tires, we slid sideways towards concrete barrier separating n-s bound traffic, went into a second 360 degree turn, slid sideways - as we started heading once again forward towards oncoming traffic the vehicle suddenly started going backwards (even though car was in drive)... We finally stopped facing oncoming traffic in sideways motion. …

My daughter was going to work - she backed out of our driveway - put the car in drive - started forward and the car engine cut off - she could not steer the car and ran into two other cars on our street - hit one in the side and the other vehicle in the front on its driver side - we called Saturn and notified them of the issue - they sent a tow truck and took it 70 miles to the nearest dealership - they said that they had to call in a special representative to check it out - he called us back and said that he could not find anything in the computer that would have caused the issue and told us to come back and get the car (about a 140 mile trip to pick up a car we were afraid of which we paid over $15000.00 for) this caused over $2000.00 of damage to her car it caused our insurance company to pay out a unknown amount for the damage to the other 2 vehicles the issue also went on her …

2005 Ion · 110,000 miles · Nov 2020

Was guaranteed that nothing was wrong with it. I originally got a 2007 Ford escape by trading in my vehicle and 500 cash. They wanted me to put down an additional 900 down which I ended up not being able to do. So they offered to put me in another vehicle that was cheaper and I would not have to put any more money on. The 2004 Saturn Ion I received on 08/23/2016 not only had clutch issues which I said I would fix, but the battery light kept coming on and they assured me that nothing was wrong with the car mechanically. We did not even make it down the road before the vehicle broke down and had to have it towed. So now the car sits in my yard and I am out my original vehicle and the 500 cash I used originally plus towing charges and a vehicle I have to pay on that I cannot drive. I want them to come get the car and give back the 500 I wasted on two junk vehicles. …

2004 Ion · 191,000 miles · Aug 2016

The Saturn Ion recalled ignition was replaced, but the problem continues to happen. On 3/20/15, I was driving on the freeway in rush hour traffic. The car turned itself off, and the brakes went out. I steered the car to the shoulder, and managed to bring it a stop eventually with the emergency brake and changing gears. I took the car straight to the dealership, per instructions from GM customer service, but haven't been able to get satisfactory information from either the service center at the dealership or GM customer service so far. The new ignition failed, causing the car to turn off while driving and my brakes to fail. This caused a serious safety risk. The recall failed to correct the ignition problem for my vehicle.
