Vehicles with delco ECM have a common issue where the fuel injectors leak into the cylinder causing engine to loose compression. The lowered compression causes hard start (if able to start at all) and if and when it starts the vehicle emits a cloud of white smoke for several minutes. When vehicle is in drive the engine idles hunts constantly. Engine stalls while driving making braking and steering very difficult and dangerous. ECM has been replaced but unfortunately the damage is done to the engine and needs a rebuild. Multiple vehicles have reported this issue from 2009 - 2013 Toyota Corolla ranging from 100 miles - 179,000 miles. It doesn't seem to have any different effect with mileage or maintenance.

01/02/2014 at 7:15am: Vehicle idled normally for approx 15 minutes while I cleared snow from driveway. I entered vehicle, put my foot on the brake and shifted into reverse. Accelerator suddenly went to full throttle. I managed to shift back into park and the engine RPM increased to red-line level. I shut off the ignition and the engine stopped. I re-started the vehicle a minute later and everything seemed to be fine. I checked the floor mat which was not close to the accelerator pedal. At least 4" away. My foot never depressed the pedal. I am a mechanical designer and I am convinced that this was not a mechanical issue. I never experienced any accelerator issues previous to this event. I am scheduling an appointment with my local dealer to look into this.

The contact owns a 2009 Toyota Corolla. The conact E stated that while driving at unknown speeds, she heard an unusual noise coming from the vehicle. The contact shut off the engine and restarted it, and the noise stopped. She also noticed that when attempting to brake in rainy weather or wet road conditions, there was an abnormal hesitation, an increase in stopping distance and the check engine warning light would illuminate. The vehicle was towed to the dealer where the dealer advised the fuel sensor was causing the check engine light to illuminate. The vehicle was not repaired or diagnosed. The manufacturer was not contacted. The failure and current mileages were 18,393. Updated 10/27/10.

Purchased a 2009 Toyota Corolla on Jan. 31, 2009. Immediately noticed "unwanted acceleration", the car wanted to go when stopped unless the brake was applied hard and did not slow down immediately when foot was taken off the gas pedal. Gas pedal did not always come all the way up when foot taken off, but would pop up if brakes applied hard. Cruise control did not work properly. Mentioned concern several times to Toyota service dept. They told me that what I was describing was normal for those cars. The car was in an accident on 12/22/09. Hit another car from behind. I think that the "not slowing down immediately when foot taken off gas pedal" was a contributing factor to the accident. There were no injuries but the car was badly damaged. Toyota sent recall notice but said VIN#'s beginning in J not affected. Our car begins with J. recently send letters to Toyota and waiting for reply.

The contact owns a 2009 Toyota Corolla. She noticed that whenever she added fuel to the gas tank, the fuel gauge didn't register that it was full. The computer chip failed to register the correct amount of fuel that was in the vehicle. She took the vehicle to the dealer three times for the failure. The dealer stated that they did not locate a failure and she should avoid adding fuel to it's capacity. The dealer also stated that if they take apart the gas sending unit they are not sure it that would determine the failure; therefore, no parts were replaced. The failure mileage was 1,000 and the current mileage was 17,200.

The contact owns a 2009 Toyota Corolla. The contact stated that the steering wheel was very loose and had a lot of "play" in it. Also, he was advised that the vehicle should receive a mpg rating of 35 for the highway. However, the vehicle only received approximately 27 mpg. The vehicle was taken to the dealer where the failure could not be duplicated. The manufacturer had not been notified concerning the issue. The failure mileage was 2,000 and the current mileage was 13,000.

Very often, my 2009 Corolla will have a very low idle, the car acts as it is going to stall. It shudders, the tach drops low, but then will come back up. It happens several times per week when I am either backing up or going from a stop into first gear. I have driven only manual transmissions for over 26 years, and this is the first vehicle I have owned that this has happened with. I fear I will be hit from behind, or T-boned when the car acts as if it wants to stall. It never has stalled, but it frightens us. As I mentioned, the car shudders, shakes when this happens to us. We feel it may have something to do with a low idle problem, either with the electronics or software. We have taken it back to the dealer a few times, but it's the famous "can not duplicate" answer. We only drive this vehicle usually from April to late October. We live in the snowbelt of Ohio and drive our 4X4 Jeep Nov. Through March. I also drive a 2001 manual transmission Honda civic, with never theses issues. I can't give incident dates, this happens frequently during each week, ever since I took delivery of this car in March, 2008. Again, this is a 2009 Corolla S.

I was driving my 2009 Toyota Corolla. Once, prior to the event in question I had briefly noticed a lack of acceleration. I pressed on the accelerator and nothing happened. The car just quit moving forward. No noise or anything. But, in a few seconds, I tried again and it seemed normal so, I decided it was just my imagination. Then, in Jan /Feb I was coming home from the gym (thankfully not on the freeway) about 9pm on a city street traveling about 30 mph. I tried to accelerate slightly to the speed limit of 35mph and discovered (again, with no warning) that my car would not move forward. None of the systems worked steering etc. But at that speed I did manage to stop. I called 911 and the police stopped 3 lanes of traffic and pushed me to the side. I waited an hour for aaa and had the car towed to the Toyota dealer. It took them a whole day to decide it was an electronic problem and to "fix" it. I was scared to drive it, but I did for maybe another month before deciding that he constant fear of it happening again (maybe on the freeway) was not worth it. The dealer made me a "deal" on a trade for a 2010 Corolla. I drove this car until 2 weeks ago. I could not live with the anxiety of having another (in my mind) electronic failure. I am one who is convinced the Toyota problem is electronic and not related to mechanics. I now have a Ford. Thank you for your attention.

2009 Toyota Corolla, "S" automatic transmission. The problem was initially identified by me when my car would not catch while on a slope in drive. The transmission would roll back. The dealership said this was normal due to a loss of pressure, however it would do it even if I barley stopped on a gradual incline for a few seconds. This has caused me to roll back unless I had one foot on the brake and one foot on the gas while to keep me steady to start. This happened at from the time I purchased the car. Recently, I my engine has been running really rough and winding at a high pitch while driving. It now intermittently goes between gears and downshifts automatically into gears that are not appropriate for the speeds traveling. This causes a drastic down speed, and example is I will be on the freeway traveling speeds between 50-65 and it will downshift and reduce my speed to 40 mph or less, then I will try to accelerate and it will redline out, as if I am in neutral and I will have no control to regain speed until it automatically pushes itself back into gear, and then increases my speed at a rapid pace, without me putting my foot on the gas. At this point, I am required to place my foot on the brake to control my speeds. The dealership has taken my car back twice and claimed to have fixed it twice based on the reads, but I have had the same problem. The reads on the computer will say that it is an electrical malfunction... however they can not identify where the malfunction is coming from. Parts have not been replaced and no repairs have been made to fix this at this time. Toyota is not assisting with the recall and I am left with lots of shop hours. Thinking about registering for the lemon law about my car, I drive apx. 1000 miles week and my car is not saving, consistent, and is a safety issue since have no control while my car malfunctions. I can only react to what is happening. It also makes a loud clunking sound, and a high winding sound when redlining.
