2006 Toyota Matrix ProblemsCheck Engine Light and Harsh Shifting
The 2005-2008 Toyota Matrix 1.8L I4 models have issues with the circuit board in the electronic control module (ECM) cracking. There is no advanced warning for the issue, and when it occurs drivers will experience:
- Harsh shifting
- Possible check engine light
- Engine stalling while driving
Toyota issued a recall for this issue, and notes the need to replace the ECU if this problem occurs.
Drivers of the Toyota Matrix may notice excessive oil consumption between oil changes, even to the extent of the engine oil warning light displayed on the multi-function display.
This issue is known to be caused by infrequent oil changes causing engine sludge, or worn piston rings.
The engine should be cleaned of oil sludge, and if oil consumption remains excessive, the engine may need new piston rings, or other internal components replaced.
To avoid this issue, change the engine oil and filter every 3,000 miles, and ensure the proper grade of oil is used.
The 2003-2008 Toyota Matrix 1.8L engine has a known issue with the valves that if left unchecked, will cause burned valves and engine performance issues.
The engine ‘breathes’ through valves that are pushed open by the camshaft, and closed by springs. When valves are closed, they seal against a valve seat. In this vehicle, the valve seat is too soft, so after the valve contacts it thousands of times, it becomes crushed. Once it is crushed, the valve can no longer make a proper seal, and the valves erode due to extreme temperature (burnt valve).
Symptoms related to this issue:
- Rough idle
- Backfiring through exhaust or intake
- Illumination of the check engine light
- OBD Trouble Codes P0300, P0301, P0302, P0303, P0304
- Loss of power
- Engine Stalling
To repair the burnt valves, the cylinder head must be removed and rebuilt, which is a costly internal engine repair, however, this issue can be prevented through inspection and adjustment of valve clearances every 40,000 miles.

2006 Toyota Matrix RecallsFront Passenger Air Bag Defect
When deployed due to a crash, the passenger side air bag can deploy abnormally, or with excessive force. The inflator may come apart, causing debris and fragments to strike and injure occupants. The dealership will replace the passenger air bag assembly free of charge to resolve the concern.
Toyota is recalling certain 2005-2008 Corolla and Matrix models because a crack may develop on a circuit board inside the engine control module (ECM). Consequences associated with this defect include: illumination of the Check Engine Light and harsh transmission shifting. The engine may not start or it could stall while driving, which can increase the risk of a crash. Dealers will inspect the ECM and replace as necessary.
Southeast Toyota is recalling 2005–2011 models for failing to comply with federal safety standards on tire selection and rims. Affected models were sold without the proper load-carrying capacity modification labels, which may cause the driver to overload the vehicle, increasing the chance of a crash. Dealers will mail the correct labels to the customer or install the label free of charge.
