I purchased the vehicle new in july 2018. When the engine started making a knocking sound I took it to a nissan dealer ship to be diagnosed. I was told "they were aware of issues with some of these engines and 2 other vechicles have already required the motors be replaced by their service department. I decided to get a second opinion so I went to another nissan dealer. This dealership confirmed that they have a factory notice stating there are issues with this motor. The dealership is tellling me they can not perform the factory required test for three weeks and if it is determined it is a defective engine it will be another 3 to 4 weeks until the engine can be replaced. In the mean time I am still driving the vehicle. In the event that this engine fails at a high rate of speed there is a potential for loss of steering and loss of brakes. Currently there have not been any recalls or notices sent out to the consumer and from what I am told it is unknown how many of these vehicles are defective and currently on the road.
2018 Nissan Titan engine complaints
Page 3 of 3: complaints 41 to 45 of 45, newest first, as owners wrote them.
When flooring the accelerator pedal (as to pull out on entrance ramp) it has diesel lag response (just take a few seconds to accelerate) and also transmission has shifting issues during this time. Sometimes intermittent I had a near miss experience when this happened to me I was pulling out onto the highway from the entrance ramp..
Truck has bad hesitation when automatic transmission is shifting from gear to gear and the rpms fluctuate badly. No low end power. This condition is worse when towing. Dealer said they all do this. I have owned 4 titans including my 2018 none of my other trucks did this. Wish I didn't trade in my 2013
In a rolling stop vehicle hesitates/lags/stalls 2nd visit they did a software up grade problem still continues not fix was told takes 2000 miles for truck to get used to new software now at 11000 miles same issue
My job requires me to travel a lot and in doing so when I'm either merging onto the interstate or needing to pull out at intersections from a dead stop . It's as tho my truck stalls and my throttle response goes dead . Leaving the other cars do come close in rear ending me . It's scary especially when I have my wife along with my three kids ranging from 8 to 12 months of age .
