2018 Nissan Titan Electrical Problems

The vehicle has recurring starting issues. The battery frequently becomes weak or completely unable to start, sometimes without warning. The issue occurs intermittently and appears electrical in nature. The vehicle may require jump starts or fails to start after sitting or after driving. This raises concern for an electrical or charging system defect. Battery has been replaced 4 times in the past 5 years. Jumped and charged numerous times in between.

I am experiencing engine stalling. I have also experienced dome light flickers or not turning on on occasion along with radio and phone charge connection not always working, like a short of some sort. Also the mirror button allowing the driver and passenger side mirrors to open close sometimes fails as if wiring is OK sometimes and other times not There is not an exact date for the issues as they have occurred on and off since 2019 I did take the truck into Nissan 11/2023 as the radio blacked out and would not turn on. I was told the Main Harness had a shorted out wire and a jumper wire should be installed. Nissan installed a jumper wire for the radio. Occasional flickering lights, charging connections, mirror operations, and engine stalling still remained.

While driving my car would almost stall on the highway, if I gave it gas while merging onto the highway it doesn't respond and then almost stall, but then respond after 2 seconds when it was not as clear to merge on the highway. I have had to replace the battery twice and been stranded in the last 3 years, the engine would pretend to start but not kick over. I have seen that this is a common problem when looking into Nissan TItan Forums

The vehicle has loss of power and goes into limp mode unexpectedly. It has done this numerous times on the interstate and regular roads. It is a safety hazard. This has occurred on several dates and we were lucky to be able to pull over safely. We we traveling in Georgia last month and Nissan didn't even have a qualified diesel tech with 3 hours of where we were. We have had ten of thousands of dollars of work to the truck and it still is not fixed. They replaced the computer screen, wiring harness, and I believe parts of the exhaust system. They had the truck for months.

Traveling home from working nightshift. I fueled up my truck with diesel and started my commute home which is 85 miles to my residence from work. 60 miles into my commute without warning and no alerts my truck suddenly lost power to everything… engine, steering, acceleration, and electrical. Final able to pull off the road with difficulty steering. Came to a stop and everything shuts off. All the warning lights lit up but no exact detail to what caused it. Had it towed to service shop after failure to start and the sound it made trying to start wasn’t normal. Technicians ran my codes and found nothing that could diagnose the problem.

1.The Engine Sub-Harness Assembly failed; melted, I feel due to the engine heat, because this harness insulation is not heat rated and melted off the wire. 2.The dashboard engine light came on and would not go off. 3.The Robbins Nissan Dealership I took my truck to in Humble, Tx. 77338 lied and said this failure was caused by rodent damage; which I know for a fact that my garage is very clean and I've never even seen any signs of rodents. 4.I first noticed a problem approximately in June of 2021 when the dashboard engine light came on and never went off. 5.By this dealership blaming it on rodent damage, this defective harness was not covered by the Nissan North America, Inc. Warranty, so I was charged $1,522.14 for this repair.
