sdonaghey Posted April 19, 2018 Report Share Posted April 19, 2018 Well I had the battery replaced early February and yesterday morning I get into the car and its dead. I had to hook up a 75A start charger and left it on for about 5 minutes and then the car just started up normally. Was heading out on a work trip, so I stopped by the dealership and have another appointment Friday to get it looked at. Car started up just fine today, so who knows what is going on.

enigma-2 Posted April 20, 2018 Report Share Posted April 20, 2018 Could be a parasitic leak. You have anything plugged into the power points? Quote Link to comment Share on other sites More sharing options...
jlsvisalia Posted May 10, 2018 Report Share Posted May 10, 2018 Yes, have had out 2016 MKX in 3-4 times now, first week out of town had to jump several times, dealer replaced battery. Occurred again, months latter, replaced battery... still could not find problem, at dealer again, cant find problem wants to blame battery. Lincoln app tracked low voltage several times but did not send notice till dead. Will not be able to trust this car, wife's car now. Carry jumper battery for backup.. less than 8000 miles...

jlsvisalia Posted May 10, 2018 Report Share Posted May 10, 2018 I have read all these posts and everyone seems to want to blame the battery, I also drive a diesel and pull a 5th wheel...and no problems, replaced batteries at 5 years and yes batteries need tending. But three batteries in less than two years and 8000 miles in a mild climate and garaged vehicle... it is a problem with the cars electrical system.. and my next step is the California lemon law if it is not fixed this time or resolved other wise. This is my first Lincoln, and already starting to miss the Edge. I thought my wife deserved a little more....sure more problems. Quote Link to comment Share on other sites More sharing options...

If the battery lasts at least 3 years then fails, that's pretty normal for modern batteries in modern vehicles. Doesn't mean something is wrong with the vehicle. If the battery is failing within 6-18 months then that is not normal. It may mean the battery is bad and needs to be replaced but that's not the root cause of the problem. Typical problems that cause this are the BCM (body control module), brake pedal sensor/brake shift interlock, park sensor (shouldn't apply to push button transmissions). You need a good dealer that is willing to troubleshoot this type of problem. enigma-2 1 Quote Link to comment Share on other sites More sharing options...
IggyAZ Posted October 10, 2018 Report Share Posted October 10, 2018 I have a 2016 MKX and have not had any problems. Oct 4,2018 My car was hard starting and the Nav screen said it was shutting down things to conserve battery. I started the car and drove it to the dealer. Said battery was bad and replaced it and drove home and drove it on the 5th, 6th. Oct 7 2018 I look at the new updated MyLincoln App and I have a msg from car saying battery is low. (Oct 7 1:15AM) Battery was at 4 volts. Called Lincoln Roadside and verified and jump started car. Being Sunday I decided to keep the car and not have it towed to dealer and place on a trickle charge after driving it around about 30 minutes. Battery showed 12 plus volts. Oct 8 2018 Drove to Lincoln dealer and told him story above.Oct 9 2018 5PM Service Provider called and said that couldn't find any issues over night and put battery on charger and to come pick it up at noon on Oct 10. The only thing that has changed it I updated the SYNC3 to version 3.0 a few weeks earlier. Not sure which build and will turn off my wifi connection when I pickup car. Could that be the drain while parked in my garage? Thanks Quote Link to comment Share on other sites More sharing options...

enigma-2 Posted October 11, 2018 Report Share Posted October 11, 2018 I could be wrong, but I think that WiFi is only on when the car is either in on (or run) or accessory. I'm sure others will chime in here, but my guess is the old battery failed, replaced with a new one and you didn't drive it far enough to give the new one a full charge. A new battery needs to be driven hard at least 1/2 hour or more to fully charge. Quote Link to comment Share on other sites More sharing options...
Adam Posted October 12, 2018 Report Share Posted October 12, 2018 FWIW Mine auto-updated to the newest version of Sync over the course of about a month or so. I only drive the car once or twice a week and probably about half an hour at a time and have not experienced any hard starting or other evidence of battery weakness.

Rick65inlosangeles Posted November 4, 2018 Author Report Share Posted November 4, 2018 My OEM battery failed in April 2016. Now the replacement has also failed. So it had a life of thirty months. Vehicle was going in for six month service tomorrow. Now they get to check the charging system and replace the battery. Quote Link to comment Share on other sites More sharing options...
Cosmos36 Posted November 5, 2018 Report Share Posted November 5, 2018 After following this topic dating to Rick's April 2016 opening post, it appears that two causative factors stand out: (1) Early MKX production model batteries (including some OEM replacements) may have been deficient from the suppliers, and (2) there is a relationship between failed batteries and number of installed vehicle options/packages. Perhaps the OEM batteries (and replacements) were under-engineered (or spec'ed) for the demands placed on them. This is no great 'voila' moment exclusive to Lincoln, other manufacturers have faced the same issues as electronic fitments have multiplied with each model being introduced. My less complex Select Plus MKX with minimal use of even the Nav, etc. seems to have a very robust battery dating to a September 2015 production.

enigma-2 Posted November 6, 2018 Report Share Posted November 6, 2018 There is another possible reason that batteries fail. How you drive. Starting a modern SUV requires a couple of hundred amperes to start. Not a big problem in a well functing battery, taking only a few minutes of driving. But if its cold, or the battery's voltage is low due to its parasitic draw, or high internal resistance, it can take a half hour to fully recharge. Short trips or city driving at low rpms may not provide sufficient time to fully recharge the charge a battery loses after cranking. A battery that is chronicly left undercharged never reabsorbs the led sulphate crystals and leads to early battery failure.

A battery that is chronicly left undercharged never reabsorbs the led sulphate crystals and leads to early battery failure. Excellent point. I only drive ~ 7K miles/year, but since my MKX gets a good workout of highway mileage at sufficient intervals on day trips of ~ 300 miles, I suspect lead sulphate accumulation issues are minimal. Batteries in my vehicles commonly last 5-7 years, e.g. the 2012 Veloster is still on the original OEM battery at less than 40K miles. In my case, engine run times are more important than RPMs for healthy batteries in almost any driving scenario. The 2.7L is a lazy engine at ~ legal speeds of 1500-2000 RPM. In city/suburban driving in lower gears, the MKX is usually running at about the same RPMs, but the drive time is much less with possibly more restarts. In either instance, 3000 RPM is seldom experienced. On the highway 3000 RPM would be considerably above the legal speed limit and I don't play 'boy-racer' between city/suburban stoplights.

akirby Posted November 6, 2018 Report Share Posted November 6, 2018 In normal driving up to 50-55 mph my F150 stays around 1200 rpm thanks to the new 10 speed tranny. That’s the main reason I’m getting 21-22 mpg. And it has so much power it rarely has to downshift much going up hills. Quote Link to comment Share on other sites More sharing options...

That’s the main reason I’m getting 21-22 mpg. And it has so much power it rarely has to downshift much going up hills. I haven't driven a drivetrain combo of the new 3.5 EB and 10-speed tranny, but my imagination runs wild thinking about it. However, even the MKX's 2.7L and 6-speed combo spooks me on occasion when I'm pulling a mountain grade in high gear at nearly idle 1100-1200 RPMs. My concern? LSPI (low speed pre-ignition) under high load & low RPM conditions with the 2.7L direct injection...I'll actually force a downshift to ease any apprehensions albeit LSPI appears to be a larger threat with small displacement modded inline four-jug GDI turbo engines. It's another reason to favor the dual injection systems of the new 3.5EB and other similar engines. And, use of the new spec supplemental API Service SN Plus motor oil will bridge the gap between the current GF-5 and future 2020 (?) GF-6 oils & assist in avoiding LSPI.

This is one reason why (combined with the ability to eliminate turbo lag and slightly improve gas mileage) there is such a surge in new cars with mild hybrid systems. I hope all Aviators will have one (even if not the plug-in model) and that Lincoln makes them standard in future ICE vehicle launches.

akirby Posted November 7, 2018 Report Share Posted November 7, 2018 There is virtually zero turbo lag on Ford's ecoboost engines, at least in my experience with both the 2.0L and 3.5L. Any delays are due to the ETC or the tranny. The instant torque of the electric motor is definitely an advantage but only in a regular hybrid, not a mild hybrid (that's usually used to describe auto stop/start).

The instant torque of the electric motor is definitely an advantage but only in a regular hybrid, not a mild hybrid (that's usually used to describe auto stop/start). Agree, there is very little turbo lag in the two ecoboost engines I've driven. I was speaking generally, referencing the article. And as both you and the article note, mild hybrids don't help with acceleration by using the electric engine directly, but by powering an “E-charger” that "spools up the vehicle’s turbo during a stop/start event and at low engine speeds to essentially eliminate turbo lag and smooth out low rpm torque deficiencies, provide up to a 25 percent increase in low end torque and 30 percent better acceleration." But to the point of this thread, they also give extra power for all the electric and electronic gizmos in today's vehicles.
