Front headlights (both sides) flicker(blink) but not all the time. When they flicker I turn them off and then turn on again, then they are fine. But I am worried that it may go bad during driving causing safety issues. Its not the bulb issues as on-board diagnostics wouldn't detect the problem. It has happened several times over last couple of weeks. . Read more...
At 44,000 miles my car has catastrophic failure due to defective parts. It is a safety issue as I stated above because many people experience the engine revving up. The transmission can also be a safety issue because it typically happens under hard braking which all of you know if you are in gear you slow down better if all of a sudden you pop out of gear you car does not have as much holding you back.

Drive by wire (dbw) throttle body system failure. Ecu throws epc code and engine power is compromised. Car may be unable to exceed 40 mph and car may buck uncontrollably. Restarting car may clear condition for a short time. Traffic negotiation was quite dangerous, as dbw system may error at any time. Dbw throttle body seems to be an answer to a problem that does not exist.
