| Traveling at 1 mph, my 2011 infiniti qx56 bumped another vehicle. there was no damage to either vehicle, but my driver airbag deployed. infiniti is refusing to look at the vehicle unless my insurance company asks them to. i feel this low speed deployment is from a defect in this week old vehicle, but cannot get help. i am concerned infiniti is attempting to ignore the problem and brush it under the rug. | |||

| 04/30/2011 | 15000 | ||
| Our 2011 infiniti qx56 cannot be properly controlled at speed when any rough pavement, pot hole, bridge connection joints, or similar is ran over. the vehicle shakes violently with little if any control by the driver. on numerous occasions the vehicle drifts out of the lane. no accidents have ever occured but at least three near misses on interstate driving have occured. at highway speeds it is scary and quite dangerous. | |||
