2003 Toyota Matrix Problems

Exhaust & Emissions -- Verified

Oxygen sensor failure may occur, resulting in the illumination of the Check Engine Light.

Exhaust & Emissions -- Verified

The Check Engine Light may illuminate due to an evaporative emission (EVAP) system fault. Our technicians tell us these EVAP system faults can be difficult to diagnose but it is not uncommon to find a failed charcoal canister or a loose or worn gas cap.

Miscellaneous -- Verified

The bolts attaching the front door window glass to the window regulator may come loose. This can cause the window regulator to become damaged and possibly causing the window glass to break. Some 2003 & 2004 models have been recalled for the issue.

2003 Toyota Matrix Recalls (Recent)

Body, Interior & Misc., April 11, 2013

RepairPal Expert Overview:

Airbags use a chemical reaction contained in an inflator module to create the pressure necessary to inflate the bags when deployment is required. These vehicles are being recalled because the front passenger airbag inflator may produce excessive internal pressure when deployed. As a result, the inflator module could rupture, causing metal fragments to strike vehicle occupants. Dealers will inspect and replace any defective passenger front airbag inflator module found.

Body, Interior & Misc., January 30, 2013

RepairPal Expert Overview:

Certain electrical circuits in the airbag system are susceptible to an internal electrical short circuit. A short circuit can create excessive current flow, damaging the electrical circuit. Damaged electrical circuits could result in an inadvertent deployment of the front airbags and/or seat belt pretensioners. This could increase the risk of injury and the possibility of a vehicle crash. Dealers will install a supplemental wire harness containing an electrical filter between the airbag control module and its wire harness to protect the control module from this electrical interference.

Code P0446 which says Evaporative Emission System Vent Control Circuit came up on my scanner. Searched online for code P0446 and found that most charcoal canisters were the problem. I took a look...

2003 Toyota Matrix Reviews

I have 126,000 on mine, the only repair other than the ordinary brakes/hoses/oil/tires, was a $286 repair to the AC for an electrical switch that went out. Car is still getting 30/24 MPG and not burning oil a bit. Outstanding vehicle.

This car has been a huge disappointment in MPG.. Advertised as 31 Hwy and 28 City (?) and the best we have done in almost 6 years is 28 on the Hwy (steady 70 mph) and about 22 around town. Wears out front tires way too fast (14K miles!), or maybe it was the Continentals that it came with. Other brands seem to do a better (about 20K miles which still isn't good). We also had a Mercedes E320 V6 up until last year that had almost twice the HP, torque, and weight and gave better mileage than the Matrix, 24 around town and 30-32 on the Hwy... Both numbers OVER the estimate for that car. And it was a LOT more comfortable.. Also more expensive and not as reliable, so it had to go. The Matirx AC system has needed an almost annual refill of refrigerant which has gotten really expensive. Mechanic can't find a leak, probably because it's too small. As someone else noted, the rear brake light is near impossible to replace and I've found that the rear wiper is a real hassle too; one mechanic who tried mangled the new blade getting it installed.

Have had to replace 4 hub caps and notice other Matrix without hub caps too. Awesome for loading! This car can carry anything. havent had to do any major maintenance until 100,000 miles and its minimal too like driving belt and hoses and brakes. I completely recommend this car.

Air conditioning went out at 80K. Screwy panel illumination when turning on heater, takes about three minutes for lamps to illuminate panel completely. Changing top center rear brake lamp is almost undo-able, almost forcing one to take to dealer to replace lamp in order not to break plastic bezel. Same can be said the cabin overhead lamp. Car emits rich gassy fumes upon start up.
Car is suppose to get 29MPG, it's closer to 24. Not very good MPG for a small car for city driving. Pros: Very flexible in payload to carry items like Xmas trees, bikes, rugs, and water heaters.

I love this car
