2007 Nissan Xterra SUV Off-Road 4dr SUV 4WD (4.0L 6cyl 6M)
Coil Packs
 We bought our Xterra very used...... 161K miles but was told that it was a solid vehicle. It had already had the transmission work done. Within 2 days of taking it home the Service Engine Light came on..... I figured it was a gas cap sensor..... WRONG..... It has been back to the dealership 3 TIMES. The first time they just reset the SEL as it came up as a random misfire..... SEL came on within 60 hours of it being home. wasn't even driven!!!!! Back in.... sent it home with replacing one coil pack...... 48 hrs later SEL is on AGAIN..... Had a friend plug it in and the code read...."Random: Multiple Cylinder Misfire"..... REALLY. I drive it 10 miles a day and the only real miles I have put on this vehicle is taking it to and from the dealership to be worked on(36 miles one way). Back in there for the past 4 days... SCARED about the reliability of this vehicle. I know it's old and has miles... But I truly like it and only drive a few miles a day... Winter is coming.... Do I let it go back or keep it????
