Check engine light came on. Had code checked at closest auto parts store, it was an evap code. Light went out, but took it to dealer to be checked. Nothing could be done because light was off. Other sensor lights came on..parking and fuel cap, took back to dealer, gas cap and O ring changed. Dealer said not to worry if lights and sensor warnings came on, that truck was safe to drive, and it was suggested I take pictures each time one came on. A couple days later the engine light and sensor warnings kept coming on. Took it back to dealer, said it was a wiring harness from engine to driver's door. 2-3 weeks later was told the wiring harness was on national back order, which tells me a lot of Titans have had this issue and there have been no recalls. The vehicle was sometimes stationary and sometimes going down the road or highway..no rhyme or reason for timing of issue.

Engine fan clutch makes excessive engine noise. Sounds like a jet engine. Dealer claims it is as designed, however, it is excessively loud, and causes extreme drope in overall fuel economy. This is a known failure that the selling dealer refuses to fix.

Error code P0527. Fan speed sensor. When A/C is on and this sensor fails, engine goes into high RPM too incorrectly cool off motor/trans. When accelerating, vehicle performs poorly (barely moves). This happened while waiting at a traffic signal to and from our destination and of course while driving. Driver is left in a precarious situation as you accelerate truck barely moves all due to a bad sensor. Sensor tells vehicle its overheating which isn't the case as temperature gauge / range is normal. Would have a better design if a) a second level verification occurred comparing truck temp before entering safe (limp) mode and 2)error code appeared on dash informing the driver and dealer of the issue. If code had appeared on dash, dealer could have looked up code when I called and simply stated "turn of A/C to resume to normal driving". dealer was baffled upon arrival with no prior reports and with no indication on where to start troubleshooting this issue. Truck had to be towed. Would have been an awful situation in areas where no cell coverage exists and 125 miles from home. Luckily we had planned to ride in someone else's vehicle that day or this actually would have occurred. End users should have a booklet of error codes and possible remedies. Turning off the A/C was the solution and an end user quick fix vs. Leaving the driver in a dangerous situation. Truck has only 11,200 miles and is a 2017 model.

Dead pedal leaving driver in dangerous situations unable to drive. Error code 0506, 0507, 2101, P1750, C1130

The drivers side rear door will lock. You can not unlock the door with the key, pushing any buttons, using the fob, nor can you unlock it from the inside. You must use the master button on the drivers door and in doing so you must lock and unlock the doors dozens of times and only then it may work the rear door. You do not need to lock the door for this to occur. The door will lock on its own. The vehicle can be unlocked, sitting for a day, and I can go out to use the vehicle and the rear door will be locked. You can be driving the vehicle and the rear door will simply lock itself. If you lock the vehicle (and it makes no difference how you do it) the rear door will not unlock with the other doors. My concern is that with a rear passenger (usually a child) and were involved in an accident entering or exiting the vehicle from the drivers side rear door would be nearly impossible because of the locking door. A very dangerous situation if fire were involved.
