I just got a 2011 Chevy Malibu with 68000 miles and it's starting to leak transmission fluid has not been an accident or anything I Drive 55 miles to work.
2011 Malibu- Engine light came on, transmission fluid leaking, car would barely move. Replace transmission connectors. Thought O ring might be bad. Ran for 1 day not leaking transmission fluid and driving okay. Next day, power steering warning light and engine light come on. Leaking again and car barely moving. Any suggestions on how to resolve problems. I'm almost to the point where i will not be buying anoth Chevy. In Jan 2017, i fixed issues with fuel relay switch and melted wires.
