I had a 2017 MKZ Select 3.0 AWD that also had that vibration at exactly 64 mph. My solution - seriously - was to go either 63 or 65 mph, and there was no vibration. It was that mph-specific in my car!
As much as I LOVED that car - and I did! - when the lease ended in April of this year I just didn't want to get the same car again. I ended up, and am very happy with, a 2020 Dodge Charger AWD.
Hi jm. If performed properly, there should be no issues.
First...I would recommend the Motorcraft replacement plugs, not any new-fangled "Double Unobtanium, triple electrode, five prong super plug" replacements.
Second...I would also recommend having a Ford or Lincoln Dealer perform the service, especially since yours is Hybrid. However, if you are looking to save money, I would recommend finding an established shop/tech in your area that you can trust (family/friends recommendations?), as opposed to a NAPA or other big box, oil change type shop. Again, especially since yours is a Hybrid and your Lincoln and Ford Dealers will be more familiar with any intricacies of Hybrid service.
Let us know how you make out and good luck.
Got over 110K miles and it's due for spark plug change as dealer recommended service. Wanted to hear some feedback on spark plug changes at 100K mile services. Any misfire issues any hints? Is this dealer specific service or Napa can handle it? I just want it get done right so to minimize dealing with misfires and coil issues after service.
A great bunch of posts... Since I started this in May my now 16 month old MKZ has 5550 miles on it - a whole 1000 miles in 4 months! But we can now go to the store for shopping and some restaurants are open and have outdoor seating which we have been enjoying 2 or 3 times a week. Plus, I had 5 stents put in 3 weeks ago for now I get to drive 30 miles 3 times a week for cardiac rehab. Yay me!!
Take care all, and drive safely!!
Hi Loki. Congratulations! She looks great!
Best of luck and many happy, safe miles!
EDIT - Loki, do you know there is a button on the dashboard to manually turn off/on the "proximity sensors" on an as-needed basis?
