Electronic Alerts & Nags
7 issues reported

When shifting into drive with sliding doors or trunk open, the Carnival lacks an immediate beep warning, only alerting after driving for a couple seconds, posing a safety risk.
The Carnival's sensors incorrectly detect sliding doors as ajar even when physically closed, causing persistent beeping; power doors require repeated opening/closing or manual intervention to resolve.
The Carnival's Idle Stop and Go auto stop-start system shuts off the engine at stops, triggering unexpected warnings at low speeds that require settings adjustments and cannot be permanently disabled.
Tire pressure monitoring shows low PSI alerts that persist even after inflating tires to spec using the onboard compressor, with discrepancies between display and actual pressure.
The Reverse Parking Collision-Avoidance Assist system auto-brakes unexpectedly when reversing with a bike rack or hitch, lacking a permanent disable option.
The driver attention warning repeatedly prompts to 'consider taking a break' on rural roads or highways due to road conditions, with no disable option.

The shared knob for audio volume and climate adjustment leads to accidental changes, like cranking heat when intending to adjust volume.
