Frequent and intermittent appearance of ABS, traction control, engine warning and 4WD Error lights on dashboard. All lights appear simultaneously and when they appear, cruise control fails, vehicle downshifts and slows substantially and engine RPMs increase 10-20% above norm for each gear. If vehicle is stopped, turned off and then restarted, conditions return to normal, only to appear again later. During a recent 3,000 mile Florida-Michigan-Florida trip, these incidents occurred a total of 56 times, all while on interstate highways driving 55-70 mph. The incidents do not occur during daily low-speed driving around town. After the recent 3k mile trip, I brought the vehicle to Nissan dealer however they would not service because dashboard lights were not on and vehicle was operating normally. Dealer advised I should wait until lights reappear, then bring vehicle into dealer service bay immediately and -€œDO NOT TURN OFF IGNITION-€ because lights will disappear. This situation is difficult because lights only appear when I am driving on the interstate, usually far from home, and they disappear upon restart. Also I would need to immediately find a Nissan dealer with an open service bay.

2019 Nissan Titan pro-4X while driving the truck, the battery voltage will drop below 12 volts (as low as $11.75 volts). When the voltage is low I've noticed that the transmission is constantly 'hunting' to find the right gear. Also the throttle control becomes 'sluggish'. when trying to lightly accelerate it will not gain speed until the transmission downshifts harshly. On a handful of occasions I've experienced an issue where I can push the accelerator pedal to the floor and it would not accelerate at all. The engine rpms would slowly increase but the truck would continue to slow down as if the transmission was not fully 'engaged'. once every 2-3 uses of the truck it will not start and acts like the battery is dead. I jump start it and then it cranks right away. I've load tested the battery and it is still in good condition. The problem was intermittent for the first year of ownership but now is a consistent problem. I've had to buy a portable battery jump starter to keep in the truck because I keep getting stranded. This is also a possible safety issue because the electrical control system is designed to operate above 12 volts. When the voltage drops below 12 volts then it is possible to render some of the vehicle control systems (including safety systems) inoperable which could possibly result in a crash causing injury and/or death. I am a control systems engineer and have over 25 years of experience in industrial electrical controls.

My 2019 Nissan Titan, with only 6500 miles, has twice failed to shift from lower gear when pulling away from a stoplight or stop sign causing me to have to pull out of traffic on a city street. Eventually, it shifted as normal. The electrical issue is more perplexing. Without having the ignition key in even remotely close proximity to, and with the vehicle stationary and not running, the vehicle radio begins playing.

Truck has a shake between 45-75 mph. Depends on rpms and tire pressure. Does not matter if it is highway or city. Most notable between 65-72mph. Have had it to the dealer 3 times. 1st time, they said it was the tires as there were new and overinflated. Told to drive it a few hundred miles. 2nd time at dealer, the road forced balanced and replaced a tire. No fix. 3rd time, a service tech actually rode with me. Let the vibrations, noted them as well. After we arrived back to the dealer, waited 20 minutes until the service tech came back. Tech stated that the truck has stiff springs and performed as expected. The tech looked like he didn't even believe it. I have heard all three of these scenarios for "fixes" from other Titan owners. It must be the line they sell us. Also, why do not all Titans have the shake? disappointing that Nissan won't acknowledge the issue or attempt to really fix it. Issue has been since day one of ownership, July 2019.
