Left a Toyota dealership after having service . It was raining outside I had just jumped on the highway and my 4 wheel drive check engine light and a third light all came on. I then drove to autozone I was told that I needed a 02 sensor. But I had just left the Toyota dealership and was told there was no problems with my vehicle. I read a post on your website and with the same concern and decided to add my complaint. I will be taking my car back to the dealership on Friday.

I have a 2002 Rav4 I purchased used in may 2010 for $9,000. A few days after purchasing it, the transmission started slipping. Almost had numerous accidents when needing to accelerate when pulling out into a busy road and the transmission failed to get out of 2nd gear into 3rd gear. Had the transmission replaced/rebuilt for $3,500, the ecm flashed for $265, 3 new oxygen sensors put in for $900. Now the car is still doing what it did even after all that money spent. Looking up on the web, found many owners had the same problem and almost all had to replace the ecm. I am now trying to get an appointment with a Toyota dealer to get this done. Very disappointed in Toyota.

Whiplash and cervical disc herniation due to negligence of Toyota rav 4 2002 transmission and ecm problems. Around 4/20/10 I took my Toyota to this dealership due to ongoing jerking and forward thrust when starting from a stop position, also the engine light was on. They kept my Toyota from 4/19/10 till 4/21/10. Reset the engine stating that it is O2 sensor problem and replaced it. Also diagnosed transmission problems but I was told by the dealership persona,l" I don't want to stamp your car as condemned, take it back and when problem gets worse bring it back" he did not warn me that if I did not get it corrected right away, I can be jeopardizing my safety and safety of people on the road. It is apparent from the paperwork they handed me that they had diagnosed a serious problem and should have corrected it right away. Around middle of may the problems with the transmission got worse, on 2 occasions the car stalled completely while going at 30 mph and then severely thrust forward again. In another 3-4 days I started experiencing severe muscle spasms and headaches. Since then I had been to er, received CT and mri showing disc prolapse and tear of my 2 vertebral discs. I have been receiving physical therapy, cervical traction, pain medication, cervical collar, and am scheduled to receive an epidural injection in 2 weeks. I have seen my pcp twice, a neurologist, 2 neuro surgeons and have received numerous medication, some with serious side effects and have detailed information about these visits. I am a physician and due to this problem have missed days at work jeopardizing my clinical care. Yesterday almost got in an accident when my car slowed down instead of accelerating and I almost hit another car, this incident made me realize I can hurt other people if I continue to drive this car. I took it in to dealer today and they are going to run a diagnosis on it again, and it might cost me 6,000 dollars. Please help.
After having an oxygen sensor replaced in the exhaust system of my 2002 Toyota Rav4 on 02/02/10, I noticed that my car began accelerating sluggishly. Approximately 50 miles after the service was performed, I noticed my car jerked when shifting through gears 1-3 and the tachometer would rev to 3000 rpms. The car then ran fine for app. 4 days with no gear slippage. A week later the gears started slipping again without warning and the car seemed to have no power when the gas pedal was fully engaged during a right hand turn to merge with oncoming traffic. The car then bucked violently. This resulted with my passenger and I becoming anxious/scared because we didn't know if the traffic coming toward us would have hit us if we suddenly lost power. I immediately drove my car home where it has remained parked and set an appointment with a Toyota dealer explaining the problems. According to similar stories from fellow Rav4 owners, there is a problem with the electronic control module causing irreversible damage to the transmission. I am taking the car to the dealer to have it 'officially' diagnosed although it only codes to have the O2 sensor replaced, which I did.
Engine control module and auto transmission failure. Bought rav used July 2007 with 109,230 mi. Check engine light was on (has remained on) but was diagnosed as O2 sensor & rav operated perfectly (live where emissions check not required). May 2009 tranny started alternating between working good, shifting rough, slipping between gears, and not downshifting at slow down or stop. Had mechanic with over 15 yrs experience at Toyota dealership check it (after hours). He was unaware of connection to faulty ecm so we thought trany was bad & he flushed tranny. That reduced frequency of symptoms but did not stop them. We still thought problem was mechanical & tranny rebuild/replace was inevitable & I drove it longer to save up money for repairs. I live on a semi-rural ohio state route with 55mph posted limit & 65mph average speed. I had numerous near misses when the vehicle would not accelerate properly or began to accelerate normally then slipped, hesitated, or refused to shift. My 18yr old son drove the rav in Dec & pulled out of our driveway in front of a semi tractor trailer rig with what would have been safe distance except that the rav decided not to accelerate. The truck was able to pass, but had there been oncoming traffic, it would not have been able to slow enough in time. Intermittent symptoms continued until 12/14/09 when 2nd & 3rd gear burned out & I drove home 20 miles in 1st. Just parts thru Toyota will cost $2000 for rebuilt tranny plus $1000 for ecm. Independent repairmen can fix the ecm for $65. Had I at least known root cause of the symptoms was ecm not tranny (Toyota's known since 2006 or before) I could have saved $4-5k & avoided 7 months of risky driving. I challenge anyone who thinks this is not a safety issue to drive one of these and rely on it when it fails in 65mph traffic. Or we can wait until someone is killed where there is enough evidence to show this problem was the cause of the accident and not poor driver judgment.

The consumer stated that the engine light kept illuminating in the 2001 Toyota rav 4. The vehicle was taken to the dealership three times. The first time they reprogrammed the computer, the second time they replaced the oxygen sensors and the third time they determined that the catalytic converter needed to be replaced. The consumer planned to replace the catalytic converter in the future. Currently the contact was driving the vehicle with the engine light on. The vehicle was not driving differently. The consumer contacted Toyota and they urged the consumer to work with the dealer, and maybe they would help her with the cost. (11/21/05) the consumer was aware of other same make model and years that have experienced this same problem.
