Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I own a 2003 Nissan 350Z, while driving at approximately 30mph, there was a sudden loss of power, and the check engine, vdc ,and slip lights all came on. Engine now runs sluggishly. I fell this is related to the NHTSA recall campaign 03v455000, but that campaign only allows for a very small VIN range of 2003 350zs. I have read many instances of this failure and situation online.”

NHTSA complaint #10361090, filed 2010-10, 105,000 miles

“While driving on the freeway my car died out and tcs slip lights came on. There was a loss of power and I had to pull over to the side. While doing so I almost got into an accident because several cars almost hit me and the area that I had to pull over had a very small median. I restarted the car and every thing was fine. The next week the car died out many times while going up a hill on the way to the Nissan service dealer. They changed 2 cam position sensors, and 1 crankshaft sensor.”

NHTSA complaint #10411840, filed 2011-07, 64,000 miles

“I own a 2003 Nissan 350Z, while driving at approximately 30mph, there was a sudden loss of power, and the check engine, vdc ,and slip lights all came on. Engine now runs sluggishly. The error code is p0340, which is crank sensor failure. I feel this is related to the ntsa recall campaign 03v455000, but that campaign only allows for a very small VIN range of 2003 350zs. I have read many instances of this failure and situation online. The recall should be expanded to all 2003 350zs.”

NHTSA complaint #10361092, filed 2010-10, 105,000 miles

“The vehicle turned off in the middle of a rainstorm when I was driving on the highway and ended up on the road where I didn't have much of a pull out which could have been disastrous if another vehicle had not been aware due to the conditions on the roadway. The result of this is due to burning of oil which the manufacturer has no idea of what causes this! They just order a consumption test and rarely does what they are supposed to! …”

NHTSA complaint #10146319, filed 2005-12, 28,000 miles

“2003 Nissan 350Z shuts down in traffic without warning. Nhtsa has this car listed on their recall list but the manufacturer says there is no recall on my particular vehicle. I contacted Nissan, they told me there was nothing they could do until I had it diagnosed by a dealership. I went to my local Nissan dealership and had my car diagnosed and they said it was the cam position sensor which would cause the car to shut down without warning, the service engine light goes on, the tcs light, and slip light, light up after restarting and it takes a few cranks to restart. …”
