2006 Nissan Xterra Problems

What owners report

Owners of the 2006 Xterra most often write about the fuel gauge failing to read correctly after refueling, typically showing empty on a full tank or a quarter tank when the tank is dry. Two other recurring themes stand out: coolant mixing into the automatic transmission fluid through the radiator, which owners report leads to transmission replacement, and stalls or loss of power while driving or pulling away from a stop. Most reports in this sample come in between about 35,000 and 140,000 miles, and many owners mention that a fuel-sender recall or service bulletin did not cover their VIN.

1. 1
   Fuel system

   Fuel gauge reads wrong / fuel level sender failure

   • 333 complaints (43%)
   • median 59,000 mi at 4.6 yrs old (315 state mileage)
   • owner-quoted repair $500 (median of 49 quotes)
   • filed 2007–2022

   After filling the tank, the gauge sits at empty or low and the fuel warning light may stay on; some say the needle climbs slowly over days or swings between full and empty. A check engine light often accompanies it, with code P0461/P0463 pointing to the fuel level sensor. Owners report being told at the dealer that the sending unit needed replacement, and several say their VIN was not included in the fuel tank sender recall, so the repair was at their own expense. A few describe running out of fuel with the gauge still showing fuel remaining. Reported from roughly 36,000 to 130,000 miles in this sample, often within a short time of a fill-up and sometimes worse in hot weather.

   Recall 10V075000

   What to check: Fill the tank and watch whether the gauge reaches full and holds; scan for stored P0461/P0463 codes. Ask whether the fuel level sending unit has been replaced and, if a recall applies, whether the VIN was covered.

   “2006 Nissan Xterra recall id from NHTSA: 10v075000 they said it doesn't apply to my car!? It's on a recall list for my model but they said my VIN is not in there system? Wth is going on with Nissan and my VIN not being in their system for a recall. Issue came up engine light on with code p0463, which is what the recall is for.”

   NHTSA complaint #10380895, filed 2011-02, 82,500 miles

   “I have experienced this failure on my current 2006 Xterra im at 39000 miles and they refuse to repair it. Warranty on this item is 36000 miles. They even tried to bs me when I said there is even a service bulletin out for this common repair. This is how it went: me - is there a current recall or service bulletin for a fuel sending unit failure or DTC p0461/2/3 dealer - let me check sir. …”

   Transmission and drivetrain

   Coolant mixing with transmission fluid (radiator failure)

   • 238 complaints (31%)
   • median 112,000 mi at 8.6 yrs old (221 state mileage)
   • owner-quoted repair $4,700 (median of 76 quotes)
   • filed 2010–2021

   Owners describe coolant and automatic transmission fluid mixing inside the radiator, often noticed as a strawberry-colored milkshake in the coolant or fluid. Symptoms reported include shuddering or jerking on shifts, slipping, revving without acceleration, overdrive engage/disengage at 40-60 mph, overheating and low heat from the heater. Owners say shops diagnosed contamination and recommended replacing both the radiator and the transmission. Several mention extended warranty notices about the radiator, and that their claim for the transmission was declined as unrelated. Mostly reported between about 75,000 and 170,000 miles, sometimes first noticed during cold weather or on a climb.

   What to check: Check the coolant and transmission fluid for color and consistency, look for a milkshake appearance, and check the radiator and transmission cooler lines for seepage. Ask whether the radiator has been replaced as a preventive step.

   “My transmission went....the coolant was leaking into the transmission and over time ruined it. Barely made it to the transmission shop who charged $3900 that I didn't have. This is a Nissan fault and I should be compensated, even though I'm over the absurd low mileage limits. Please help!”

   NHTSA complaint #10534930, filed 2013-08, 115,000 miles

   “I have warranty extension notices sent out by Nissan. They are for a leak in the radiator they may go into the transmission..my radiator was replaced because the dealer said it had a leak. There was no fluid in my garage or driveway.. Now my transmission had to be replaced 76993 miles. …”

   Transmission and drivetrain

   Harsh shifting, slipping, or transmission failure

   Mentioned in 6 of 60 sampled complaints

   Owners describe the automatic transmission shuddering or jerking into overdrive at 40-60 mph, high revs with slow or no acceleration, and occasional loss of propulsion while driving. In some reports the engine would rev to 2,000-3,000 rpm while the vehicle barely moved or would not move at all from a stop. Shops frequently diagnosed transmission failure and recommended replacement; some owners say they were told transmission or valve body work was needed. Mostly in the 90,000-145,000 mile range in this sample, often appearing as a shift-quality change before full failure.

   2 related service bulletins

   What to check: Test drive at steady 40-60 mph under light throttle and up a hill to feel for shudder or delayed engagement. Check transmission fluid level and condition and ask whether the transmission has been replaced or serviced.

   “I was driving about 45mph when my vehicle jerked and briefly lost propulsion. This has happened approximately six times on different occasions and at different speeds. I feared that it would happen while pulling out in traffic. About two months after the first incident my mechanic has diagnosed that the transmission has failed, which is related to this phenomenon.”

   NHTSA complaint #10496765, filed 2013-02, 82,000 miles

   “I was driving Nissan Xterra on the busy street and suddenly I notice smoke coming from under the hood. I stopped the car on the closest parking lot and tried to go away from the car. I was scared it will blow up. After few minutes the smoke stopped coming from under the hood. I called towing and my mechanic told me it is transmission problem. It was truly horrible experience.”

   Engine

   Stalling and loss of power while driving

   • 103 complaints (13%)
   • median 105,168 mi at 8.5 yrs old (95 state mileage)
   • 5 mention a crash, fire or injury
   • owner-quoted repair $2,500 (median of 22 quotes)
   • filed 2006–2026

   Complaints describe the engine shutting off at a stop light or at speed, sometimes restarting normally and sometimes repeating over weeks. Others report the vehicle losing motive power or refusing to accelerate from a stop, with the engine revving but the truck not moving. Some owners tie the stalling to electrical or fuel supply behavior, one mentions the engine control relay and another mentions an unreadable OBD port; in several cases the vehicle was not diagnosed or repaired. Spread widely from about 90,000 to 225,000 miles in this sample, with no clear pattern of weather or driving condition.

   Recall 10V5170003 related service bulletins

   What to check: Ask whether the vehicle has cut out or hesitated and whether the engine control module relay or IPDM has been serviced. Have a scan tool confirm the OBD port communicates and check for stored codes.

   “The first incident was a couple months ago when my car just decided to stop in traffic all the sudden. Just shut down. Then yesterday I was driving to work and a car in front of me decided to slow down. When I hit the breaks to slow down the car would not accelerate back up it decreased. I could not get it to go. I restarted the car and it turned on and went again. I looked at this website and saw all the complaints.I have had all the same issues with stalling, not starting, and no acceleration. …”

   NHTSA complaint #10749583, filed 2015-08, 117,400 miles

   “As I came up to stop at a red light, the Xterra began to shudder and the tachometer started rising and falling until I finally stopped, then the tachometer dropped below 500 RPM and the truck turned off. Restarted it fine, but it stalled again. I quickly figured out that although it is an automatic, I needed to drive it like a manual. So I put it in neutral, started it again, it did not stall, then I revved the engine to 2,000 RPM and put it into drive. Off I went, and it did not do it again that day. …”

   Timing chain guide wear and engine noise

   • 46 complaints (6%)
   • median 94,000 mi at 9.0 yrs old (35 state mileage)
   • owner-quoted repair $2,123 (median of 11 quotes)
   • filed 2006–2024

   A small number of owners report a tapping or chirping noise from the engine on cold starts that becomes more noticeable over time, attributed by technicians to worn plastic tensioner guides on the secondary timing chains. Complaints say the guides wear well after warranty and that continuing to drive carries risk of further engine damage. Separately, one owner reported a shaking vehicle traced to an engine misfire and a catalytic converter replacement. Reported anywhere from about 14,000 to 160,000 miles, with cold-start noise as the commonly described first sign.

   What to check: Listen for a rattle, tap or chirp at cold start and ask whether timing chain guides or tensioners have been inspected or replaced. A pre-purchase inspection that includes listening at startup is worthwhile.

   2 excerpts from owner complaints in NHTSA records

   “This vehicle was designed with plastic tensioner guides to the secondary timing chains. The engine is designed with an interference timing chain which means that if the timing chain breaks, it results in catastrophic engine failure without warning. Although Nissan did not design the timing chain as a maintenance item, the plastic guides wear out long after the vehicle warranty expires. …”

   NHTSA complaint #11204794, filed 2019-04, 134,700 miles

   “Secondary timing chain shoe failure. Known problem with multiple Nissan vehicles due to inferior quality product, as explained by service technician. Technician stated that multiple Nissan vehicles come in to the shop weekly with this issue. It occurs so often, the service technician had examples of the inferior and worn parts in the cabinet to show customers. Expensive and timely issue to fix. If left unfixed, will cause serious damage to engine.”

   NHTSA complaint #10449371, filed 2012-02, 53,000 miles

Buying note. Check the fuel gauge operation right after a fill-up and scan for fuel-level codes, since that is the most frequently reported item and recall coverage varies by VIN. Also inspect the radiator and transmission fluid for contamination and listen for cold-start engine noise, as both point to repairs that owners describe as expensive.
