The 2006 Mazda5 has 4 recalls, the most serious being a fire risk: under high engine RPM, heat can build up excessively in the exhaust system, particularly around the main silencer, and cause the vehicle to catch fire.
The remaining recalls both involve the sliding door latch. In cold weather, water can work its way into the manual door latch mechanism and freeze, which jams the latch components and can leave the sliding door unable to close and latch properly. If the door appears shut but the latch has not fully engaged, the door can swing open while the vehicle is moving. These recalls are scoped to vehicles registered in colder-climate states where freezing temperatures are common, and prior repair attempts did not fully resolve the issue, resulting in more than one campaign addressing the same underlying problem.
