What 90 owners told NHTSA about the 2018 Nissan Titan

The crankshaft broke on original engine then my warranty company CARS plus protection sent another engine with 80k miles and mechanic installed and made it 60miles and the crankshaft broke on that engine as well.

The truck left me stranded on the side of the road resulting in a total engine failure. Zero warning signs. Truck was towed at my expensive resulting in 29 days without the vehicle while nissan replaced the engine

I was driving the truck down the interstate with the cruise set at 70-75 mph and without warning, the truck starts shaking violently and making very loud noises from the wngine and then the engine shuts off and power steering is lost while traveling at highway speeds in traffic. The failure was diagnosed as a crankshaft failure which snapped the crankshaft in the engine. The quote from Nissan to replace the engine out of warranty varies between 35k-42k which TOTALS this vehicle for an engine failure that they are at fault for. Nissan knowingly sold vehicles with faulty engines by putting the safety concerns and financial burden for the public to the wayside. This needs to be addressed soon before someone is seriously injured due to Nissan’s negligence and recklessness for customer safety.

My vehicle was driving down the highway at 70 mph when without any warning the engine shut off resulting in the loss of power steering. I had to navigate through traffic to get to the shoulder of the road. I had the vehicle towed to Nissan dealership after a couple weeks I was made aware that the engine needed to be replaced. The truck suffered. A broken crankshaft and main fuel components were replaced as well.

Was driving down the interstate going 70 mph truck started loosing power without any warning or check engine light's. Truck started vibrating violently to the point almost lost control of truck. Dealer says broke crankshaft in motor truck only has 77k miles on it. This should be looked into as it’s happening a lot with models with the Cummings diesel motor. Please look into this before someone is killed. Thank you for keeping us safe.

Elk hunting on a mountain towing trailer with UTV, road was somewhat rough in 4wheel drive suddenly engine goes into limp mode. It took almost 4 hrs to get off the mountain in limp mode....once off towed vehicle 200 miles to nearest dealer (redding,ca). Cause: A sensor in the overflow for the radiator failed and put the truck into limp mode. There was no actual engine failure or any low coolant. Just very poor design on cummings part....

While Driving in normal Driving conditions, The Auto at 30 mph will Rev the RPMS up to as much as 5000 rpm before the Transmission will catch and accelerate loosing the ability to accelerate on demand when needed such as merging on to a Highway of speeds of 55 mph or higher. This behavior happens almost every single time acceleration is demanded and is not due to a lack of ATF fluid in the transmission. As the vehcile has done this after The local Service center of nissan in my area had just done the 20k mile check up. This has been on going and constant behavior since I purchased This nissan Titan in 2021. Truck currently has 35k, and has had all service suggestions done. This is a danger to my family and myself as lack of power can cause extreme danagers when you are trying to gain speed to merge onto a busy highway and you are running out of roadway to gain speed and you have to use the emergency lane to have access to safe area to gain enough speed to safely merge. This is a well known issue with this model, as I have been seeing other owners complain for sometime online in forums, when I researched if anyone else had this issue.

The truck loses power and drops to 3000 rpm. When it gets to 3000 rpm the trucks shakes as the rpms jump from 3000 to 3500 rpm. I have videos that site will not allow upload of.

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.

while I'm driving my truck, it has a Cummins Diesel engine, at certain times I guess that the engine goes through a regen process, when it odes this process then the cab is filled with noxious gases. This process last a few minutes and causes you to lower the windows to get rid of the toxic gases. I reported it to my Nissan Dealer twice when I took it in for it's service, they acted like they had never heard about it before and told me that there was no issue with my truck. that I had to drive it more to get it to stop ding it. Is this normal or are we being poisoned or getting cancer from these events?

1. THE VEHICLE HAD TO BE BRAKED HARD ON THE HIGHWAY TO AVOID A CAR THAT FAILED TO YIELD WHILE MERGING. THE OTHER VEHICLE THEN BRAKED HARD AND I ATTEMPTED TO ACCELERATE TO GET IN FRONT BUT THE VEHICLE WOULD NOT RESPOND TO THE GAS PEDAL. THE ENGINE DID NOT SHUT OFF, BUT THE TRUCK WOULD NOT REV THE RPM'S OR HAVE ANY RESPONSE TO THE GAS PEDAL FOR ABOUT 3 SECONDS. LUCKILY A COLLISION DID NOT OCCUR. 2. WHILE TAKING A RIGHT HAND TURN ONTO A STEEP INCLINE DRIVE FROM A HIGHWAY THE TRUCK ONCE AGAIN WOULD NOT RESPOND TO THE GAS PEDAL. THE TRUCK WAS JUST SITTING ON THE INCLINE FOR ABOUT THREE SECONDS BEFORE IT RESPONDED TO THE GAS PEDAL AND CLIMBED THE HILL. THERE WAS A VEHICLE FOLLOWING BEHIND INTO THE DRIVE AND HAD TO STOP TO AVOID COLLIDING INTO MY REAR END AS THE TRUCK WOULD NOT GO FOR A FEW SECONDS. I AM NOT EXACTLY SURE HOW TO DESCRIBE THESE TWO INCIDENTS OTHER THAN IT IS A "DEAD PEDAL" FOR SEVERAL SECONDS WHEN PROPULSION IS TRULY NEEDED

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.
