2004 Toyota Matrix ProblemsExcessive Oil Consumption
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 timing chain tensioner on the 2003-2005 Toyota Matrix is designed to use oil pressure to keep tension on the timing chain. When it develops a leak, it can no longer provide tension, and the timing chain will begin to make a slapping or rattling sound at all times.
If left in this condition, the timing chain may fail, leading to costly internal engine repair.
To correct this issue the timing chain tensioner must be replaced with the revised part.
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.

Brakes have been grinding for a little while now and I'm worried about the rotors being damaged from it. How could I at least get an idea of what condition they're in?
2004 Toyota Matrix RecallsUnexpected Airbag Deployment
The airbag control module can fail prematurely due to electrical noise beyond the tolerance it was designed for. As a result the front airbags, side airbags, and/or seatbelt pretensioners could deploy inadvertently while the vehicle is being operated, increasing the risk of personal injury and/or a crash. Dealers will replace the airbag control module and front and/or side impact sensors as required to correct this concern.
This limited regional recall is for vehicles currently registered or first sold in southern Florida, along the Gulf Coast, Puerto Rico, Hawaii, the U.S. Virgin Islands, Guam, Saipan and American Samoa. Upon deployment the passenger airbag inflator could rupture, increasing the risk of personal injury. Dealers will replace the passenger side air bag inflator to correct this concern. If a replacement inflator is not available, as an interim measure, the dealer will disable the front passenger air bag and advise the customer not to use the front passenger seat until a replacement inflator is installed.
This limited regional recall is for vehicles currently registered or first sold in Florida, Puerto Rico, Hawaii and the U.S. Virgin Islands, and equipped with Takata-brand air bag inflators. Upon deployment the driver and/or passenger airbag inflator could rupture, increasing the risk of personal injury. Dealers will replace the affected airbag inflator modules to correct this concern.
