Vehicle started to begin takeoff really slow and hesitant, and then shift really hard with a jerking motion into second. Not safe for taking off with traffic or crossing intersections. Very scary to operate. Could ruin transmission, shafts, and other parts. Quote from dealership to replace ECM is around 1500+. then transmission around 3000+. I am currently dealing with Toyota back and forth on getting repair approved. Parts are available. All necessary calls have been done up the chain of command. They are not warranting this claim at this time.

My husband was driving to the grocery store when he heard a grinding noise. Soon after, the check engine light went on. He immediately took our vehicle to the local Toyota dealer. We soon discovered our 2003 Toyota rav 4 has a defective ECM and the transmission has been severely damaged due to the ECM. It costs over $5,000 dollars to replace the ECM and the transmission. We are unable to drive the vehicle because we feel it is dangerous for ourselves and others.

2003 Toyota Rav4. Started having vague problems last year with the car not wanting to shift at the appropriate times. On Dec 22, 2010 we took it to greentree Toyota in danbury ct and they replaced an ECU unit. It seemed to be working better but not optimal. It started shifting bad again and at times not wanting to shift at all so we returned the car to milton ruben Toyota in augusta ga on 4/25/11. These symptoms are sporadic and some days it runs better than others. Upon driving the car they are telling me that because the check engine light is not on and the codes are fine, as well as the fact that they can not get it to reproduce any of the symptoms I am complaining of I.e. difficulty merging into traffic B/C it will hardley go at times, upon taking off on an incline, at times, it will not go over 30 mph with the gas pedal to the floor, at times it will go over 4.5 RPM before it decides to shift, I will not let my daughter drive this car because I am afraid she will pull out and not be able to go in time. The symptoms are very obvious but I am being told that they don't see any symptoms at all and the car is running beautifully and that they can not put forth a claim to Toyota for this issue without a set criteria. This is so frustrating and now I will have to pay them money to tell me that the car is fine when it is not. I so wish I had not bought this Toyota and will never buy a Toyota again.

Hi, I am writing to complain about my 2003 Toyota rav-4. I have experience some troubles with what seems to be the ECM and transmission. I have been in extremely close calls for a major accident because of the transmission malfunctioning while accelerating. The ECM/transmission suddenly downshifts or accelerates out of sequence and it causes the entire vehicle to abruptly jerk in a forward/backward motion. The estimated cost for repairs is well above $4,000 dollars for what does not seem normal for a vehicle that only has 100K miles. In an economy like this, it is difficult for me to obtain that amount of money for repairs. I trusted Toyota for its reliability but after this my thoughts have changed. I am extremely disappointed to be dealing with this frustrating issue. I have read many more complaints on this issue on edmunds.com under costumer reviews. I wish that Toyota recalls this problem like they have for other models since this problem can be life threatening.

In October, 2010 my 2003 Rav4 started acting sluggish and shifting poorly. It would almost stall out in traffic and several times I was almost rear ended because the car would balk shifting from second to third gear. I took it to arlington Toyota in palatine, Illinois. They could find nothing wrong. In January, 2011 the problem got worse. The dealer reflashed the ECM module which controls the transmission. The problem got worse. They told me that I would need a new ECM.cost $1400. Mileage out of warranty so it would not be covered. They contacted Toyota regional who also said they would not cover it. I contacted Toyota customer relations but they also said even though I had received a recall notice, they would not cover the cost.

I was recently warned that my 2003 Toyota Rav4 had many, many transmission complaints. Not 2 days later, my rav began showing signs of transmission failure. I researched the issue on the internet to find that there were an unusually large number of owners with similar problems, but found no relief with Toyota. After taking my vehicle to the dealer for analyzing, I was informed it needed a new transmission to the tune of almost $4,000. This is on a vehicle that has been driven by only me and had preventive maintenance done regularly.

My wife's' 2003 Toyota Rav4 just started having transmission problems. We took it immediately to a repair shop. On the way there were serious problems with the transmission shifting which was particularly dangerous during the acceleration and deceleration in intersections. The dealer repair shop said the computer and transmission would need to be replaced. I called Toyota customer service and they told me a service bulletins had gone out, but that our particular VIN was not part of the bulletin, even though the problem is exactly the same as has been widely noted and recognized by Toyota.

Toyota Rav4 2003 has transmission problems. The mechanic said this is common with this car so I did some research and quickly found that many other people had the same problem. There is a problem with the computer asking the car to shift to first and second gear at the same time. This causes the car to slow down then rapidly accelerate.

I was about to merge with traffic on a local highway when I stepped on the gas pedal and the car did not accelerate. It terrified me because there was a tractor trailer to my left that almost hit me. As I pressed harder on the pedal to accelerate the car, the engine made a loud revving sound, and the car started to jerk forward, in the sense that there seemed to be transmission slippage: Sometimes the car accelerated harshly while at other times it was like it was on neutral. This occurred with no warning at all, as something like this had never happened before, nor was there any hint that something like this would happen. This transmission slippage occurs at low speed, right at those crucial moments when you need the car to accelerate because you are merging with traffic, or are crossing an intersection after having stopped at a light or stop sign. After searching online, I found many similar complaints. People reported that the problem was the engine control module (ECM), so I had that fixed, and now the car seems to be running fine. The worst thing is that online people discovered that Toyota issued an internal memo in 2006 notifying dealers of this problem, but it did not notify the owner, let alone recall the cars and have the problem fixed. Apparently, Toyota did not feel the problem was serious enough, though I am convinced that it was only luck that I survived that day on the highway!

I own a 2003 Toyota Rav4 with only 63K miles on it. The transmission failed while my son was driving the car. We took it to a local transmission shop to have it fixed. The transmission shop had so many problems trying to install a rebuilt transmission that they contacted a Toyota dealership. They were told that the year and model Toyota I have was know to have a faulty computer that caused transmission failure. It was then towed to the dealership. They deemed the computer faulty and fixed the car free of charge. Once the Toyota dealership put in the new computer, the transmission still wouldn't work. It is back at the transmission shop. I have not had the car for over four weeks. I am now in the process of contacting Toyota to get reimbursed for the cost of the rebuilt transmission.
