2003 Toyota MR2Fuel systemTransmission & drivetrainEngine & cooling

The design of the computer controlled power train makes throttle, transmission and starter inter-dependent. My vehicle has repeatedly lost power and coasted to a stop. The vehicle has been recently inspected by a toyota dealer, who says there's nothing wrong with it. But the vehicle operator's manual anticipates stalling while underway and gives directions to re-start - sometimes successful, sometimes not and the vehicle has to be towed, in my experience. Manual directions (page 153): if your engine stalls...

while driving ... Reduce speed gradually, keeping a straight line. Move cautiously off the road to a safe place... Manual transmission, na sequential manual transmission: turn the ignition key to the ?Acc? Or ?Lock? Position. Approximately 5 seconds after, try starting the engine again. If your engine will not start, see ?If you engine will not start -? On page 150 of this manual. How can one "move cautiously off the road to a safe place", if the engine won't run? This car is unsafe as manufactured, imo. *Tr

2003 Toyota MR2Transmission & drivetrainEngine & coolingFuel system

Purchased used from carmax and within 100 miles the transmission light came on, it would not shift out of first gear. I had it delivered to have the vehicle looked at, and it refused to go into reverse gear next. When they attempted to drive it only 1 st and 2nd gear would work. After having a brand new transmission installed from toyota by aamco transmission as soon as the vehicle made it back to the car dealer, it started leaking fluids all over the lot. The transmission solenoid had quit working and starting spraying hot fluids all over the vehicle. It has been towed back for followup repairs and they are considering refunding due to excessive vehicle damage. *Tr

2000 Toyota MR2Engine & cooling

Similar to the hundreds of other early affected 1zz engines (mr2, corolla, matrix, vibe and others) my engine is currently burning 1 quart every 400 miles. My mechanic has noted that it is due to piston rings or the off shaped bore in earlier 1zz engines. So the engine is burning oil and my head is also being starved for much needed oil. I am now jeopardizing the oxygen sensors and catalytic converter which were just replaced. *Tr

1993 Toyota MR2Engine & cooling

I was driving at approximately 30 mph when suddenly the throttle went wide open and the tachometer went to maximum rpms. I depressed the clutch while the engine continued to rev at maximum rpms for approximately 45 seconds. I was startled and did not have the presence of mind to turn the ignition switch to the accessory position. Eventually the revving subsided from maximum but continued to surge until I finally parked the car and shut the engine off. Upon restarting the engine the operation was normal however there was a loud knocking noise and the result of this malfunction was engine damage that required rebuilding the engine. *Tr

2000 Toyota MR2Engine & cooling

In june of 2006 I heard a ticking noise in the engine of my 2000 mr2 spyder. When I brought t to the dealership they told my I had spun a bearing due to oil starvation, even though I had my oil changed every 3000 miles. The dealership replaced the bearings and crank and the noise was gone. 2 Months later, after driving 4000 miles and having the oil changed after 2500, the ticking noise returned. The dealership again stated that I had a spun bearing due to oil starvation. When investigated further the tech said...

2002 Toyota MR2Engine & cooling

I bought a toyota saquoia limited 4x4 used in 2003. When I tookit to a friends house her husband siad I should get that ticking noise checked out. I told him that all of the suv's at the dealership made the ticking noise. Well, he was right. When I took it in to be inspected I was told that I had a cracked manifold. The mechanic said that all of the toyota suv's and trucks have problems with their manifolds. If this is true, why have they not done a recall to correct the problem? I manifold is not a cheap part to replace.
