Odometer Fraud. The contact's aunt purchased a 2007 Toyota Corolla. It was discovered that there was a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 180,000, and at the time of registration, it was discovered that the mileage was 195,000.
I had my vehicle in idle and retracted my drivers side power windows down to pull my nephew into my lap to say goodbye to him. At this time about 5 minutes after starting my car the window panel, as well as below the door panel towards the speaker a heavy smell of burning plastic spread around the car and white smoke started billowing out through the slit the window glass retracts back into. At this time I shut the car off and waited until the toxic smoke had escaped. This issue with the master switch has been reported by Toyota for 2009 corollas only. This could have posed a serious health risk had it gone unnoticed. After doing the diagnostic, it was found that it was in fact a faulty switch that probably "got wet". If a car is catching on fire after a simple florida rain shower, that is not the consumer's fault. Faulty manufacturing is the case here. …
Tl* the contact owns a 2007 Toyota Corolla. When the contact started the vehicle in the driveway and depressed the accelerator pedal, the vehicle surged with a high rate of speed and crashed into the garage. The air bags did not deploy. There were no injuries. The insurance company had the vehicle towed and was to have a facility inspect the vehicle. The vehicle was not diagnosed. The dealer was not contacted. The manufacturer was notified. The vehicle was not repaired. The approximate failure mileage was 130,000. Consumer stated unintended acceleration at great speed.
The car wouldn't break a few months back causing it to smash into the person infront of me ever since then and getting repaired nothing has fixed it.
Shortly after having the ssp, computer replaced under recall, the check engine light started to come on and go off intermittently. I brought it to the dealership to have it checked out and was told that the fault code #741 was a transmission code and they had top remove the pan to check it out for a cost of $350.00. We are the first owners of this car and being in the auto field for over 30 years I told them that the transmission felt no different than the day we got the car and suggested that the problem might be in the computer that was replaced but they insisted that they would have to remove the pan to investigate and wouldn't even consider the possibility that the computer might be the problem. I refused to be charged $350.00 to have them find what I already knew and then incur other charges for them to troubleshoot to find the true cause of the light. …

Started car in December 2015, two weeks before christmas. Dash lights did not come on automatically as they always did at night, nor did they come on after manually turning them on, but after 10 minutes of driving they came on. Next night again no lights, this time I hit a bump, dash lights flashed on then off again until next bump in road and came on and stayed on. Next night, no lights. Hit bumps in road but still no lights. My dash lights never came on again. I looked online and found that post after post after post of 2007 Toyota Corolla owners are experiencing same problem. That's when I found out I also had no tail lights! Mechanic checked fuses and tail light relay, all fine. Checked for loose wires, no loose wires. Mechanic puzzled. Walnut creek Toyota dealer wants $350.00 just to look at it. After seeing all these posts with same problem, Toyota dealer should know what it is! …
Looked up a recall on the emc of 2007 Toyota corollas. My car was rear ended on 12/31/2014. Ever since, my car has been having electrical problems. My radiator fan is not working and had to be hot wired by a mechanic for it to stay on while running. My ac is not working, my shifter is stuck in park which is caused by a bad solenoid. I have had it inspected for over 8 hours by certified mechanics at midas, and they couldn't fix it. They said that every test they did was reading that nothing was wrong but my ac and radiator fan and solenoid are not working. My car stalls out occasionally, it wont start sometimes, and it is idling louder than before.
Tl* the contact owns a 2007 Toyota Corolla. The contact stated that the power outlet was defective. When the power outlet was used, a burning odor would penetrate through the vents. The vehicle was taken to the dealer several times for the failure. The dealer replaced the power outlet fuse several times, but the failure was not corrected and the power outlet fuse continued to fail. The manufacturer was made aware of the failure. The failure mileage was 12,000 and the current mileage was 50,000.
Started car this morning and the check engine light came on. Took to parts store and hooked it up to the computer and found codes (p2401, p043e, p043f, p2402, p2419) everything I have researched comes back to EVAP canister failure, and possible wiring failure. More research shows these issues causing people getting stranded and others with no problem other then light, and others with a strong gas smell. If this causes a gas smell, then a potential fire hazard is formed.
