11MKZ

Alright final update. Lincoln dealer agreed that the coolant hose was the issue. They fixed it (after 4 days) and reimbursed my monies, also while reading the services they did while it was in looks like they fixed other issues that the body shop had done that I hadn't realized. They installed some fasteners to a splash shield and rerouted a wiring harness for a coolant sensor. Unfortunately I did not get a chance to talk to a manager my Fiancé and I were in a rush and grabbed the car and left. I will however post on dealerrater.com as I am not happy at all with how things have gone with them. We will not be taking the MKZ back to them and I hope from here on out I am able to fix the remaining issues that arise (I could have fixed this but why do that when I can bitch at them). If it ever needs serviced I will be taking it to the Ford dealer that did the first diagnostic I have a friend who used to work at the shop I am employed at who works there. He kept me updated the entire time it was there lol. Thanks for the input everyone.

Update - Took the MKZ to a Ford dealership told them the issue and about the accident. Got a call the day after (tuesday) and said they wanted their transmission guy to look at it. He then determined that the coolant hose from the transmission to the cooler was collapsed from the routing the body shop did. Seems it isn't completely collapsed if I can drive around town but once the system is under a larger load it can't flow enough to keep cool. Paid the the diag fee and took it to the Lincoln dealer down the street where the work was done. Explained the situation and rather than ask why I chose to take it to Ford first, the service writer literally called me an idiot for taking it to the Ford dealer not a Lincoln dealer. Which obviously pissed me off pretty good and I told him I didn't trust the techs there after the terrible job on the repair work they did to which he said it wasn't his department so he didn't care. Will definitely be the last time I take it there unless its more issues related to their work. And I will be talking to a manager once I pick up my MKZ. That was this afternoon(thursday) so I'm hoping they agree on Fords diagnostic fix it reimburse me so I can drive it around again.

Agreed with the accident issue, we got it back on May 1st and haven't had an issue until now. The hybrid system showed all OK immediately after the accident radiator was replaced along with entire front bumper fogs lights, headlights, ect. On my 2011 MKZ Ford Dark Green Antifreeze is the specified coolant. I doubt the warranty has been voided that would be absolutely ridiculous I think. Was trying to diagnose and fix myself but if I can't figure it out by tuesday may take it to the dealer and have the extended warranty from Carmax pay for it or at least have them diagnose it for me. The MECS pump does not have a malfunction monitor on it simply a plug for power. On the FEHs the MECS pump is common and it too has no MIL code for just the pump simply puts the car into safe mode from what I have researched. Woman turned in front of me and must not have seen me. Hit her left rear wheel and bent that in at a 45* angle. Caused just under 15K in damage thankfully on her insurance.

Thanks for the replies. Went into the shop tonight, the reservoir was slightly low topped off with Ford dark green (Vehicle was in a front end collision 3 weeks after I purchased it, Dealer did a bad job fixing it and I have been fixing their mistakes as I find them). There is not a single drop of coolant under the vehicle or on the protective shield when I took it off. It doesn't look like I can pressure test the MECS side, does anyone know if I pressure test the coolant reservoir for the engine if it will pressure test both? I touched the MECS pump and it was vibrating as it should and the coolant could be seen flowing in the reservoir. When doing a vehicle self check there are no issues everything checks ok. When scanning for codes there are codes in the memory (the two already posted). When doing a self test with the Snap-On Modis Scanner there are no codes that pop up. According to the flowchart if the codes don't pop up in a self test I'm supposed to go through a symptom based diagnostic which I will do further tomorrow as well as try to get the freeze frame data. I am at the moment thinking the MECS pump is intermittently going out, which seems to be a common Ford issue(not saying for everyone but pops up often) from all their previous hybrids

Hi all first post and hopefully someone has some insight. 2011 MKZ Hybrid started to act horribly while trying to go to WV. Whenever we(my Girlfriend and I) would try to go up a hill the car felt like it would shift into neutral and the Pull over safety light illuminated and lost power. Did the vehicle check and it showed a issue with the hybrid system. Turned around(after it acted up several times) to go to the shop I work at scanned the vehicle and showed 2 fault codes. P1A14 - Hybrid Powertrain Control Module - Transmission Disabled. P0A3E - Generator Inverter Over Temperature. Looking up the codes on ALLDATA both show to replace the transmission as the first step and then to check to see if the engine is seized. I haven't done any diagnostic, haven't checked transmission fluid, and while driving it acts perfectly fine until the light appears and you can feel the transmission bump out of drive. With it being a holiday I wont be doing anything with it for now and luckily I have a spare car for my girlfriend to drive while it gets looked at. We purchased it a few months ago from carmax with an extended warranty and just rolled over 21k while driving back home so there is a chance it will be taken care of. I was wondering if anyone has had a similar issue or codes? Tried to look up similar issues on google, nothing came up and I apologize if this has been discussed before.
