2006 Toyota Matrix Problems

What owners report

Owners of this model year most often describe the engine stalling or losing power while driving, frequently with the check engine light on and sometimes traced by dealers to the engine control module (ECM). A second common theme is premature and uneven tire wear on the inside edges, which many owners link to the rear alignment and report replacing tires well before expected. Airbag recall notifications and unavailable replacement parts also appear in the sampled complaints.

   Engine stalls or loses power while driving

   • 32 complaints (19%)
   • median 47,000 mi at 4.3 yrs old (31 state mileage)
   • owner-quoted repair $867 (median of 7 quotes)
   • filed 2007–2015

   Complaints describe the engine quitting at speed, at intersections, or when pulling into a parking space, often with the check engine light coming on and sometimes with no restart until the car sits for a while. Several owners say the dealer replaced the engine control module (ECM) or throttle body, and a few note the same fault returning afterward. Some say the dealer could not duplicate the problem on the first visit. Reported from roughly 11,000 to 140,000 miles, with many between 30,000 and 75,000 miles.

   Recall 10V3840005 related service bulletins

   What to check: Ask whether the ECM has been replaced or reprogrammed and whether campaign 10V384000 applies to the VIN. During a test drive, watch for a check engine light, hesitation, or rough idle, especially after the battery has been disconnected.

   “2006 Toyota Matrix stalled when I was driving. It would start, but then it would stall in approximately one minute. I tried to start it many times, but it would stall after a minute. Towed car to Toyota dealer and they replaced the ecu.”

   NHTSA complaint #10336793, filed 2010-06, 55,000 miles

   “The ecu on my 2006 Toyota Matrix died suddenly, after the ecu failed the car to halt immediately. Luckily for me this did not happen on a freeway , in which case I would have been rear ended and possibly seriously injured. When my car was towed into the dealership , the tech at the service desk guessed that it was the ecu as he had seen quite a few of these fail. After tests they determined it was the ecu. The ecu was replaced by the dealer as it was under warranty.”

   Tires

   Premature, uneven tire wear (cupping)

   • 36 complaints (21%)
   • median 16,400 mi at 2.2 yrs old (27 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2006–2011

   Owners describe tires wearing out far earlier than expected, with cupping, scalloping, and heavy wear on the inside edges, along with road noise or vibration that grows with speed. Many report replacing all four tires at low mileage and repeated alignments that did not stop the wear; some say a dealer replaced a rear differential or suggested an aftermarket rear shim kit. Complaints also describe the dealer attributing the wear to the tires or to driving habits. Reported mostly between about 5,000 and 25,000 miles, with some owners seeing a second or third set wear the same way.

   Recall 10V035000Recall 10V036000

   What to check: Inspect the inner edges of all four tires for cupping or uneven wear, ask for alignment records, and check whether a rear shim kit or suspension work has been done. Listen for tire roar or vibration on a highway test drive.

   2 excerpts from owner complaints in NHTSA records

   “First and only owner. Excessive tire wear on all 4 tires at only 20,000 miles. All tires have excessive wear at the inside rim. I didn't have any accident and my driving was never aggressive. The tires have to replaced at 20,000 miles. The concerns are the new tires will be gone in about another 20,000 miles. Toyota should correct this problem with the car.”

   NHTSA complaint #10244680, filed 2008-10, 20,000 miles

   “2006 Toyota Matrix. Tires wear out every 16,000 miles. The problem is in the rear axle. Toyota has consistently told me there is no problem. Today I am on a discussion board and find it is a common problem for the Matrix/vibe. The solution is an aftermarket rear wheel shim kit costing $50 plus labor. Why is Toyota allowed to continue denying the problem exists and not recall and correct the problem.”

   Vehicle speed control

   Sudden or unintended acceleration

   • 26 complaints (15%)
   • median 40,000 mi at 4.3 yrs old (25 state mileage)
   • 10 mention a crash, fire or injury
   • filed 2007–2015

   Complaints describe the car surging forward or revving on its own while parking, at a stop with the brake applied, or at low speed, in some cases resulting in a low-speed impact. Owners say the brakes sometimes did not hold the car, and that dealers either found nothing wrong or could not duplicate the event. A few report the engine returning to normal after shutting off and restarting the car. Mostly reported under about 30,000 miles, often at parking or stop-and-go speeds.

   What to check: Ask whether any throttle or pedal-related campaign applies to the VIN and whether the throttle body or ECM has been serviced. On a test drive, check for a high or hanging idle and confirm the floor mat is properly secured.

   “I was parking our Toyota Matrix, 2006 and it jumped ahead and I hit the car in front of me. My accident report indicated a jump in the car. When I read about the Toyota accelerator problems, I am convinced our car suffers the same flaw and I hope that 2006 will be included in the recall. I have never had any other accident and I am over 50 years old.”

   NHTSA complaint #10306896, filed 2010-02, 60,000 miles

   “November 18 my 2006 Toyota Matrix began to accelerate uncontrollably after filling up tank with fuel. I pulled the vehicle to the side of the road turned off the engine. The engine then would not start so it was towed to windsor Toyota dealership. Test drove & check for water in tank elimated code p0171 and gave me free injector cleaner. Should the dealer check gas pedal recall on his 2006.”

   Air bags

   Airbag recall notification and parts delay

   Mentioned in 5 of 60 sampled complaints

   Several complaints concern the passenger airbag inflator recall: owners received notices but were told the replacement part was not yet available, or were quoted long waits for an appointment, and some describe crashes where the airbags did not deploy. Others report trouble confirming recall status through the VIN lookup. Compliance and service paperwork describing the inflator issue are also covered by bulletins. Reported at various mileages from about 60,000 to 120,000 miles, typically years after purchase.

   4 related service bulletins

   What to check: Check the VIN for open airbag recalls and ask for documentation that the inflator replacement was completed; confirm the airbag warning light behaves normally on startup.

   2 excerpts from owner complaints in NHTSA records

   “Vehicle completely stopped in a line of traffic. While waiting to move on, with my foot on the brake,the engine all of a sudden roared and the vehicle shot forward and hit the vehicle (approximately 5 to 7 feet) in front of my vehicle. The air bags did not open and the hit to the other vehicle was more like a punch. I tried to stop my forward thrust but the brakes would not hold the vehicle. Upon striking the other vehicle the engine roar stopped and everything seemingly returned to normal. …”

   NHTSA complaint #10203648, filed 2007-09, 28,450 miles

   “Your website where I enter my VIN returns a request was invalid message. One or more parameters were invalid. Nothing is explained. Why did this message show?”

   Transmission and drivetrain

   Transmission jerking or harsh shifting

   • 29 complaints (17%)
   • median 45,556 mi at 4.2 yrs old (25 state mileage)
   • 5 mention a crash, fire or injury
   • owner-quoted repair $1,200 (median of 7 quotes)
   • filed 2006–2015

   Owners describe hard jerking on the shift out of first gear, stalling in heavy traffic, and, in one case, bearing noise from a manual transmission. Some report the dealer replaced the ECM to address the shifting behavior, while others were quoted substantial repair costs. One complaint notes the car rolling backward on a steep hill from a stop. Reported from about 7,000 to 142,000 miles, with several between 70,000 and 120,000 miles.

   1 related service bulletin

   What to check: Drive at low speed and through several upshifts and downshifts, listening for clunks or noise, and ask whether any transmission or ECM work has been performed.

   “I was on a steep hill at a stop sign. I had let go of the brake to step on the gas because it was my turn to go and my car rolled backwards dramatically to the point where my tires where screeching for a few seconds till I was able to get off the steep hill. This is not the first time it has happened, I usually avoid streets that have a steep hill because this happens every time I'm on a steep hill. I've noticed this has happened for several years now.”

   NHTSA complaint #10543155, filed 2013-09, 137,000 miles

   “As I was driving to work on december 28, 6:50 am I gradually felt my car slowing down so I tried accelerating with no success! When I looked if I had forgotten to lower the safety brake, I checked my board and saw a check engine sign so I pulled of to the gas station (lucky there was one when this happened and no traffic). I called for a towing and turned of the car. When the towing guy came, he tried my vehicle and nothing seemed to be wrong except for the check engine sign that was still up... …”

   NHTSA complaint #10373181, filed 2010-12, 116,849 miles

Buying note. Check the VIN for open recalls, especially the airbag inflator and ECM campaigns, and ask for service records showing whether the ECM was replaced or reprogrammed. Inspect tire wear closely and budget for alignment or suspension work, since owners often report short tire life on this model year.
