| Problem Category | Number of Problems |
|---|---|
| Vehicle Speed Control problems | |
| Accelerator Pedal problems |
Vehicle will accelerate on its own when put in gear as soon as consumer takes foot off brake. This has happened. Dealer cannot remedy problem. The master cylinder leaks brake fluid and brake pedal was low. The consumer uses brake excessively because of lack of engine deceleration. There is coolant leak at right rear intake manifold.
When foot is removed from accelerator pedal to decelerate, it takes approximately ten seconds or more before vehicle starts to slow down. Speed plays no factor in deceleration. When brakes are applied, pedal goes to floor. Taken vehicle to dealer & mechanic refused to write up problem until representative drove vehicle.
