Dodge Grand Caravan Problems
RepairPal has identified the most common problems with the Dodge Grand Caravan based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
A dirty throttle body may cause low engine idle speed or frequent stalling, as oily residue blocks air flow in the throttle when the throttle is closed. Throttle body cleaning may be necessary to correct this condition. Our technicians caution against spraying cleaner directly onto the throttle body as this may damage the throttle position sensor (TPS).
On higher-mileage vehicles, engine oil leaks from the valve covers and front crankshaft seal are common.
A "tapping plate cage" on the driver side frame rail may cause a squeak or tick noise while driving, this is often misdiagnosed as a suspension problem. The tapping plate is a threaded plate which accepts one of the front sub-frame mounting bolts. The "cage" of the threaded plate may be touching the frame rail causing noise as the vehicle is driven. "Adjusting" the rear tab on the tapping plate cage so it no longer is touching the frame should eliminate this noise.
A malfunctioning switch in the steering column can cause the front windshield wipers to self-activate or not turn off. A failed windshield switch will require replacement.
Often when replacing the front left wheel speed sensor, the wrong part is used (it's from a later model year). If the wrong sensor is used, it can damage the wheel speed sensor wiring.
An intermittent loss of speed control can happen soon after the transaxle input or output speed sensor has been replaced. The problem is most likely caused by bad connectors.
The speedometer may become inoperative due to a failed vehicle speed sensor (VSS), . A failed sensor will require replacement.
A delay in the transaxle engagement (greater than three seconds) may have multiple causes, including a defective pump, defective internal lip seals, valve body components, park-reverse-neutral-drive lever switch, and the output speed sensor. Proper diagnoses will be necessary to determine the exact cause.
Under heavy acceleration in temperatures above 80° F, an engine spark knock can be heard. The powertrain control module may require replacement.
Voltage spikes can cause erratic behavior in the electrical system (lights, locks, wipers, head lamps). This is often caused by relays. Inspection and replacement of relays is required; revised relays are available.
Sometimes the vent windows' latch can pop open; if it will not stay closed or rattles, the latch assembly should be replaced.
