2007 Nissan Xterra Problems

What owners report

Owners of the 2007 Xterra most often report coolant mixing with automatic transmission fluid, which is followed in many cases by transmission slip, loss of power or complete failure — often with no warning light beforehand. The second frequent theme is a failed fuel level sending unit that makes the gauge read low or empty and turns on the check engine light. Engine noises traced to the timing chain, plus air bag warning lights after recall work, appear in a smaller share of the sample.

1. 1
   Transmission and drivetrain

   Coolant mixing with transmission fluid (radiator cooler)

   • 218 complaints (39%)
   • median 113,000 mi at 8.4 yrs old (195 state mileage)
   • 2 mention a crash, fire or injury
   • owner-quoted repair $4,750 (median of 66 quotes)
   • filed 2010–2025

   Owners describe the radiator's internal transmission cooler failing and allowing coolant and transmission fluid to mix, producing a brown or pink milky fluid visible in the radiator or overflow tank. Symptoms commonly begin as shuddering, slipping or delayed shifts, a racing engine at highway speed, or a periodic clunk uphill; several complaints describe total loss of power while driving and a tow. Shops and dealers typically say the radiator must be replaced and often the transmission as well, with owners frequently citing repair quotes in the thousands. Spread across the sample from roughly 80,000 to over 180,000 miles, with many reports in the 100,000–150,000 range.

   What to check: Inspect the radiator and overflow bottle for a milky, pink or brown fluid, and check the transmission dipstick for the same; ask whether the radiator has been replaced or an external cooler added. A transmission-to-radiator internal leak can progress quickly, so a clean fluid check and recent service records matter more than mileage alone.

   2 excerpts from owner complaints in NHTSA records

   “I've noticed that Nissan has been under investigation for receiving a number of complaints from consumers in regards to sudden, catastrophic transmission failures in 2005-2010 Nissan pathfinder, frontier and Xterra's. Well I am writing to tell you that my 2007 Nissan Xterra has fallen victim to this. …”

   NHTSA complaint #10490939, filed 2013-01, 124,000 miles

   “Our 2007 Nissan Xterra, purchased brand new, began to overheat. Upon checking the fluids I noticed the coolant level was dangerously low. I was certainly puzzled where the fluid had gone because there has never been any visible leaks or any warning lights or any other symptom to draw my attention. I began to look into the situation because I was puzzled and quickly learned of the massive number of Nissan owners experiencing the same problem. Sadly, I was now one of those victims. …”

   Fuel system

   Fuel gauge reads wrong, sending unit failure

   • 202 complaints (36%)
   • median 55,000 mi at 3.9 yrs old (185 state mileage)
   • owner-quoted repair $450 (median of 29 quotes)
   • filed 2009–2021

   Complaints describe filling the tank and having the gauge read only part full, drop to empty, or stick at about a quarter tank, usually alongside a check engine light and codes P0461–P0463. Some owners report running out of fuel on the road because the gauge showed fuel that was not there. Dealers generally diagnose the fuel level sending unit and quote replacement of the sending unit or pump assembly, and several owners were told their vehicle identification number was not included in a related fuel system recall. Mostly reported between about 27,000 and 95,000 miles, frequently soon after refueling.

   What to check: Note the gauge reading right after a fill-up and ask whether the sending unit has been replaced; scan for stored P0461/P0462/P0463 codes. Until it is fixed, tracking distance per tank is more reliable than the gauge.

   “My Nissan Xterra is having the fuel gauge problem with the fuel level sending unit. At this time its intermittent. I called Nissan and filed a complaint with them they ran my vehicle id # that doesn't show up as one having this problem. They want me to pay for a diagnostic check for the fuel level sending unit and repair. This is a recall item. I was mail a notification r1010 10v-074.”

   NHTSA complaint #10344751, filed 2010-07, 106,000 miles

   “Filled the tank 100% but it only showed 1/4 of a tank of gas and then goes to empty immediately after. The full tank did not register and the check engine light came on. I visited an auto shop and was told that it was a fuel sending unit/sensor and that it was no longer covered after 30k miles. I have seen the same problems posted online and there needs to be a recall if this is the case for many 2006-2008 Nissan xterras.”

   Air bags

   Air bag warning light on

   • 26 complaints (5%)
   • median 90,150 mi at 8.5 yrs old (18 state mileage)
   • 4 mention a crash, fire or injury
   • filed 2007–2025

   Complaints describe the air bag warning light staying on or flashing, sometimes with a passenger-side air bag deactivation indication, and in some cases the light appearing after recall repair work was performed. Dealers have pulled body codes and identified parts needing replacement, and some owners were told the condition was normal or that recall parts were not yet available; one owner reported no deployment in a rollover crash. Mileage varies widely, from near-new to over 150,000 miles, and several reports follow recall service.

   Recall 08V690000

   What to check: Turn the key to the run position and confirm the air bag light goes out after the self-test; ask whether open air bag recalls were completed and whether the light was on before or only after that work.

   “Takata recall, the airbag faulty light is flashing in the dash of the car even though the repair was preformed at Nissan for the recall. Flashing allways in park or moving.”

   NHTSA complaint #11254770, filed 2019-09, 188,942 miles

   “The contact owns a 2007 Nissan Xterra. The contact stated that the air bag light illuminated, which indicated that the passenger side air bag was deactivated. The dealer and manufacturer stated that it was a normal occurrence and could not be repaired. The VIN and engine size were unavailable. The failure mileage was 20 and current mileage was 3,000. *updated 12/12/07 updated 12/12/07”

   Engine cooling

   Overheating with coolant loss and no visible leak

   Mentioned in 4 of 60 sampled complaints

   Owners report the engine running hot with the coolant level dropping noticeably and no puddle or warning light to explain it. On inspection the loss is often traced back to the radiator assembly and, in several cases, to coolant moving into the transmission circuit. Cooling system flushes and radiator replacement are the usual remedies described. Reported from roughly 85,000 to 130,000 miles in the sample.

   2 related service bulletins

   What to check: Check the coolant level and color when the engine is cold, look for residue around the radiator and overflow bottle, and ask whether the radiator or water pump has been replaced.

   “Noticed a strawberry colored fluid coming from the radiator overflow reservoir. Checked the radiator and found that the whole cooling system had the same color of fluid. I took my Xterra to a radiator shop and had the cooling system flushed and antifreeze replaced. I was told that what happened was that the transmission cooler had failed and that antifreeze and transmission fluid mixed together and went through the cooling system and transmission. I first got the radiator replaced and cooling system flushed again. …”

   NHTSA complaint #10735854, filed 2015-07, 160,000 miles

   “Last month the car seemed to start slipping gears when I got up to around 40 miles per hour. It was sporadic and once I let me foot off the gas for a second it seemed to clear and be ok. I started to see a slow leak of what I thought was oil in the garage where I parked the yesterday. When I mentioned the leak to a buddy and also told him that my heater was not working, he said we should check the coolant in the radiator. When we opened the radiator cap, there was a slimy brownish sludge all over the bottom of the cap. …”

Buying note. The most consequential thing to verify on a 2007 Xterra with an automatic is the radiator and transmission fluid, since mixed coolant and fluid is the failure owners describe most and repairs can be expensive. Confirm the fuel gauge reads correctly after a fill-up, listen for timing chain noise at cold start, and check that any open air bag recalls have been completed.
