2018 Nissan Armada Complaints

  • Electrical System, engine 05/12/2026

    My 2018 Nissan Armada has had SO MANY issues (probably 15-20) with not starting when cranked. Something is draining its battery. We have had to change the battery so many times (usually 2-3 times every year or two.) This happens without any notice! We have been stranded in other cities, stores, &/or at work. We have tried having it checked out by different repair shops, replacing batteries in key fob, replacing battery MANY TIMES, and checking the brake pedal switch. We are at our Witt’s end with Nissans!

  • Engine 04/13/2026

    UNKNOWN - engine developed knock that could potentially lead to catastrophic engine failure during normal driving conditions, causing loss of control or inability to stop. NTB19-057a is a technical service bulletin issued by manufacturer - cylinder 7 scuffing with a short block or complete engine replacement as the fix. Manufacturer will not replace engine outside of vehicle warranty period, even with documented maintenance proving engine failure is not due to lack of being maintained.

  • Unknown Or Other 02/01/2026

    My battery kept dying every 6-12 months for the past 8 years! Every time I took it to the dealer or to other mechanics, they ran diagnostics tests and told me nothing was wrong, even though I knew something was definitely wrong. We found out that MANY other Nissan Armada owners AND Infiniti QX80 owners have been dealing with the exact same thing. They showed us how to cut a wire, that would bypass the IPDM smart charging system. Ever since cutting that wire, my car has been working perfectly, and no more battery dying! Please look into this so others don't deal with what I did. Here's the video that we received that explains everything: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
