2001 Infiniti QX4
Engine not specified
| 247380 mi ¤1000 |
This car is falling apart but is still going, although very slowly. Had to replace radiator, a few pipes, filters but it’s getting expensive to keep this car running. It guzzles too much gas and hardly can accelerate. Needs a new engine, maybe. |

SUV was stalling during long trips in hot weather. Very intermittant - once every couple of weeks and unable to reproduce at dealers shop every time it was brought in. |

The intermittant starting/stalling become more consistent and eventually all the time. The problem was a leak in the cooling lines of the throttle body. However, the repair affected the engine computer, which needed to be replaced (with used one). |
