There are occasional reports of daytime running light problems.
The 2005-2008 Toyota Corolla 1.8L I4 models have issues with the circuit board in the electronic control module (ECM) cracking. There is no advanced warning for the issue, and when it occurs drivers will experience:
- Harsh shifting
- Possible check engine light
- Engine stalling while driving
Toyota issued a recall for this issue, and notes the need to replace the ECU if this problem occurs.
The bolts attaching the front door window glass to the window regulator may come loose. This can cause the window regulator to become damaged and possibly causing the window glass to break. Some 2003 & 2004 models have been recalled for the issue.
The Throttle Position Sensor can get out of adjustment due to wear in the throttle body or due to carbon build up. This will cause the idle timing to advance more than 30 degrees which will cause very high HC and NOx emissions. Conversely, the Throttle Position Sensors can wear out and not properly advance the timing which causes a lack of power and poor fuel economy.
