Power train

3 reports
“Automatic transmission is slipping badly. Results in temporary loss of power & speed. Taking my foot off the gas pedal, for two-to-three seconds, seems to remedy the situation. It's quite scary losing control of the vehicle during that period. Below, I am identifying an "approximate date"; however, this issue has been ongoing for quite some time - At least one, perhaps two, years. A mechanic's remedy may be checking the transmission fluid, or having the fluid replaced. I ensure I keep the fluid at its' proper level and I'm not replacing the fluid. I don't believe any transmission fluid ever needs draining and replacing - I think that's a scam when it's suggested!”

Engine

2 reports
“The contact owns a 2009 Lincoln MKX. The contact stated while driving 45 MPH, there was an abnormal sound coming from the front passenger’s side of the vehicle. The contact stated that the engine power reduced message was displayed and the wrench warning light was illuminated. The contact pulled over to allow the engine to cool down. The contact removed the oil cap and stated that the engine oil looked like chocolate milk. The contact took the vehicle Precision Tune to get the oil changed and was informed there was a major coolant leak. The vehicle was not repaired due to the cost. The manufacturer was made aware of the failure and the contact was informed to call the NHTSA Hotline for assistance. The approximate failure mileage was 125,000.”
