2012 Nissan Frontier Owner Comments

problem #6

The 2012 Nissan Frontier has a rubber grommet on the clutch pedal which triggers saftey switch. The grommet goes bad and the vehicle will not start. Cannot be jumped. Must be towd or fixed on the spot. These grommetts go bad in 15,000 miles and it cost $15 for a new one. You cannot maintain a piece of rubber on te clutch. Rediculous

I first noticed the incident today in a downtown area, speed of 35 mph. Upon removing my foot from the accelerator the RPM dropped to 1000, not lower, and the vehicle continued to move at the 35 mph. At every opportunity I was able to duplicate the event. As I entered our street I braked reducing speed. The vehicle RPM remained at 1000 and the speed was lower, but requiring braking to slow completly. I inspected the accelator pedal area, with my wife to verify that nothing was blocking the accelator. My wife and I took the vehicle on another test drive and was able to duplicate the event, crusing at 35 mph with no foot on the accelerator, RPM at 1000. The outside temp. Was approx. 102/104F. Weather clear and dry. The vehicle was used over the weekend for a round trip of approx. 700 miles. The vehicle is serviced on a regular basis, mileage upon parking was 18,135. I think this is potentially a serious safe issue.

Engine coolant smell after driving. Radiator gets low on coolant. Overflow coolant level is full when engine is cold. Radiator is not pulling coolant back from the over flow when the engine cools down after being operated. This indicates a leak. Nissan dealer did a visual inspection but aid they found nothing.

The contact owns a 2012 Nissan Frontier. The contact stated that the vehicle would not accelerate beyond 30 mph. The vehicle then began jerkin violently and caused the contact to bounce off a side railing. The vehicle was taken to the dealer, who advised that the electric control module failed. The vehicle was scheduled for repairs. The manufacture was contacted. The VIN was not available. The failure mileage was 25,012.

Again! while traveling apx 55 mph, vehicle lost power, engine surging, sputtering, some warning lights on dash illuminated. Was able to restart and drive another mile or 2. no luck. Vehicle was towed 80 plus miles back to dealer. Another crank position replaced and problem was fixed for now, this is the second time in less than a year!! id this happened on a busy multi lane highway while towing something it might have had a different outcome!!

Driving on the interstate the A/C stopped working then the engine overheated. The next day went to a dealership and they said this was the fourth engine that had the exact problem. The engine has to be change and I was 300 miles away from home. Loosing money and time.
