“We were driving locally at normal speed and the car suddenly lost power as though we ran out of gas. We were able to slide somewhat to the side of the road. After a while, the car started again and we thought it was just some kind of fluke. We are senior citizens and do not drive a great deal however we thought all was well and in august we road on the highway 95 to connecticut and the exact same thing happened after we arrived and were pulling into a local mall, once again we had to be towed. If this had happened to us on 95 we would have been killed. …”
NHTSA complaint #10544405, filed 2013-09, 100,250 miles“I was driving on the parkway with my family and I was traveling at approx 60 MPH. Out of no where a tcs and ABS light came on the I decreased to 5 MPH without warning and couldn't go faster. I had my foot all the way down to the pedal and vehicle wouldn't drive. This appears to be a camshaft sensor issue from what I see. There was a recall on this issue but I'm being told my vehicle was not an affected car. Others have all had the same happen with this same vehicle and I find it strange that because our VIN numbers weren't recalled that we are out of luck. …”
NHTSA complaint #10491481, filed 2013-01, 135,000 miles“I was driving my car at 35mph when suddenly the engine stopped without any warning. All the indicator lights got illuminated at that point. That time I was able to get my car stared again. Later same day it happened again. In the mechanic shop I was told that the camshaft sensors have to be replaced. I paid more than $600 for two new sensors,and than I find out that there was a recall in december 2003, campaign # 03v455000. Am I eligible for a reimbursement? Mileage on the odometer is 39350 and the old parts are available.”
NHTSA complaint #10296636, filed 2009-12, 39,350 miles“For the last year the engine of my 2003 Infiniti I35 has been making a noise upon acceleration (while the engine is under stress) especially on inclines. I have brought the vehicle to pepe Infiniti, they've duplicated the noise, yet they haven't done anything to rectify the problem although the vehicle is still under the manufacturer's warranty. I have contacted the Infiniti corporate office to no avail. I am filing a complaint to hopefully get some resolution regarding this matter.”
NHTSA complaint #10160890, filed 2006-06, 40,000 miles“The car suddenly loses throttle control under normal driving conditions; the engine return to idle speed . I was driving on the expressway and all of a sudden the check engine light came on and the car started slowing down. I pressed on the gas pedal all the way down but the car refused to accelerate. I managed to pull over and stop the engine. And then restarted the car and it seemed to work ok for a while and then did it again. I managed to get it to the dealer and it has been there since while they try to figure out why this is happening. This problem started happening about a year ago. …”
