Toyota RAV4

"O2 sensor heating element failed"

"Replace all oxygen sensors and catalyst converter"

"old and not working properly"

"Catalytic converter failed under warranty."

"The emissions indicator came on and the mpg dropped a little. Did not affect car operation and ignored until I had to repair to pass the Maryland emissions testing."

"The fuel intake tube needed to be replaced and the cap because the emissions says there is a leak. The mechanic spent many hours trying to find the small evaporation leak, but could not. So, I am careful to not top-off when I fill the tank. That seems to keep the emissions/check engine light off"

""Check Engine" light due to fuel injectors needing replacement"

"Engine keeps cutting out. Issue still not resolved."

"Wiring became corroded and had to be replaced"

"The timing chain gear on the camshaft has a variable timing function and after changing the sensor we will have to change the gear and that will cost over a thousand dollars"

"O2 Sensors seems to fail quickly and need replacing often. (Two banks of sensors)"

"I have had to replace O2 sensors nearly a half dozen times. I don't know why, other than they were not working and then obviously causing other malfunctions."

"check engine light on - findings were oxygen sensor failure - car was running fine"

"A check-engine light keeps coming on indicating the 'evap system'. All parts have been replaced so we're guessing a sensor is failing."

"Oxygen sensor failure, total of 2 thus far. This vehicle has 4 total sensors, and the sensor itself costs $250 plus cost of replacement"

"Check Engine Light warned of the issue. Not unexpected because of the age of the car"

"Check engine light on, need 2 new O2 sensors and catalytic converter--seems like too much to spend on 14 yr old car"

"Check engine light, bad 02 sensor. Could have gone up to $2200, cost $500"

"The check engine light goes on for several months and off for a few months. The diagnostic check shows catalytic converter but it is not the problem. Without having a spare O2 sensor or cat converter to swap out to confirm. I live with the light on"

"O2 sensor heating element failed"

"All four O2 sensors have had to be replaced over the last three years"

"The oxygen sensors frequently go bad. I believe its due to the ethanol gas we put in our vehicles"

"Had to have an o2 sensor replaced"

"Warning light came on and therefore may not pass inspection."

"Have now needed to replace all four O2 to date"

"I have had to replace the O2 sensor twice in the last 2 years, i.e., about 12,000 miles. I think this is excessive."

"Engine light came on; I had it checked and replaced the sensors"

"Engine light indicates O2 sensor problem. A few years ago, we heard there had been some sort of recall but that we were outside of the timeframe. So we sent for/replaced the motherboard and the engine light stopped coming on. This past year, the engine light started coming on again."

"While driving, the computer malfunctioned causing the vehicle to sputter as though it was not getting gas. I almost got rear ended by a tractor trailer. Thankfully, the Toyota dealer replaced the computer and the vehicle has been running perfectly"

"This was a recall problem that Toyota busted their asses trying to straighten out, but if my wife had not complained (bitched about) when three times the car was "FIXED" but didn't run correctly we would never have solved the problem!"

"over a 5,000 mile period had to replace 3 out of 4 O2 sensors. I'm ready to sell now"

"Engine check light on in conjunction with weak acceleration and rough running. Fix was to replace power train control module; total cost about $2000."

"Oil pan gasket is wet and will soon be dripping"

"Valve gasket leak causes oil to burn (smoke) on start up"

"Leaky valve head gasket causes oil to burn when engine is first started, emitting blue smoke of a minute or so. Once engine is warmed up, it's fine. Not worth the expense ($3K or so) to fix."

"oil was leaking from the area of the oil filter, everytime I had my oil change I would check to see if they put the filter on tight and would see a small drop of oil on the ground and would just think it was residue from the oil change right after my"

"Leak at main seal"

"leaking around gasket which was replaced"

"slight oil dripping from a cracked seal where engine is attached to chain housing"

"Had to replace gaskets & seals"

"Problems for the auto transmission to engage in the lower gears, would hesitate and slip, buck, before changing to next gear. Common problem with 2001 to 2003 RAV4"

"Transmissin began slipping and jerking suddenly. We took the vehicle to the garage. So didn't do excessive damage to the transmission. Computer was replaced and transmission tested. Cost more than $1500. No further problems"

"Car started bucking when accelerating. Thought transmission was going out, Research on Internet revealed 2001-2003 rav4 computers have a defect that sends wrong signals to transmission causing it to buck and that Toyota refuses to acknowledge or fix"

"At 222,000 miles, this car needed a new transmission computer"

"The electronic device that tells the transmission when to shift was defective and needed replacement. So I guess that would be the Transmission Computer. ??"

"The ECU module had to be taken out, since it made the car stop shifting gears. It was over $900 repair and should have been a recall, since it is a common problem with this year car"

"Transmission computer failed at 110,000 miles. RAV4 forums helped me determine what the issue was and an after market replacement (core swap) for ~$300 saved me the price of a new transmission + computer module. Toyota warranty expired at 80,000"

"ECM module defective and caused gear slippage. Had to replace the ECM for $1500"

"The computer failed causing a transmission failure"

"Harsh shifting from transmission. Replaced ECM as possible option as opposed to replacing transaxle. It worked!"
