enigma-2 Posted October 15, 2018 Report Share Posted October 15, 2018 Are towing a trailer when it comes on? The powertrain malfunction light is warning to reduce load on the engine, especially speed. If you continue, the computer will put the engine into the limp-in mode to protect it. Need to pull the codes to see exactly whats causing it. Could be a malfunctioning sensor or something serious. Quote Link to comment Share on other sites More sharing options...

tberg Posted December 27, 2018 Report Share Posted December 27, 2018 For the second time in the last 3 months, our 2016 MKX with about 20000 miles on it lost all transmission function with the accompanying "Powertrain Malfunction" warning. This time around, it's been two weeks and the dealer is waiting for parts. In the discovery phase, they found significant damage to the trans as well as to what was previously repaired. And this time, it stranded my wife and pregnant daughter on the street. I am now getting to the point that I'm wondering if we'll trust that the car is reliable and if the repair will be sufficient to keep it from happening again. We got rid of our Buick Enclave after having the transmission rebuilt five times. I'm quite concerned that we're headed in the same direction. We don't use it to tow anything, it's my wife's grocery getter. Very disappointed. Quote Link to comment Share on other sites More sharing options...
tberg Posted January 1, 2019 Report Share Posted January 1, 2019 Update! So much damage was done internally, that Lincoln decided it was more efficient to replace the entire transmission as opposed to repairing parts. Tranny arrived yesterday and we should get the car back by next weekend. I am hopeful that this is the last time this kind of repair has to be done for a long, long time. My two Jaguar XKRs, a 2002 convertible with 171,000 miles, and my 2010 5.0L coupe with 155,000, have never had transmission work done except for fluid changes. I don't like transmission problems especially based on our experience with the Buick. Quote Link to comment Share on other sites More sharing options...
