2006 Nissan Titan Problems

What owners report

Owners of the 2006 Nissan Titan most often write about oil leaking from the rear axle seals, which sprays differential fluid onto the rear brakes, and about rear differential noise and failure. Complaints also cover broken rear leaf spring shackles, cracked exhaust manifolds, and slow or sometimes unexpected ABS and brake behavior. Many of these reports arrive between roughly 30,000 and 130,000 miles, and several owners say dealers replaced seals or whole rear axle assemblies under warranty.

   Rear axle seal leak onto brakes

   • 169 complaints (39%)
   • median 60,000 mi at 4.9 yrs old (156 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $800 (median of 17 quotes)
   • filed 2006–2024

   Owners describe gear oil seeping from the rear axle seals at the wheels and being thrown onto the brake rotors or drums, sometimes on one side and later the other. Complaints say the leak reappears after a seal or rear end replacement, and one owner reported repeat failures within a few hundred miles. Several owners say the dealer replaced the seal or the axle assembly under warranty, while others were told it was normal wear and were quoted several hundred dollars per side. Most reports come between about 15,000 and 130,000 miles, with several under 35,000 miles.

   What to check: Look under the rear of the truck at the inside of the rear wheels and brake backing plates for oily residue, and ask whether the rear axle seals or axle assembly have been replaced. Check the differential fluid level as well.

   “I have a 2006 Nissan Titan. I was on vacation with my wife and granddaughter this past week when I noticed the braking on my truck felt wrong. It took much further to stop than it should. It could have caused an accident. I pulled over to a rest area and noticed a burning smell coming from the rear of the vehicle. I checked the fluids and everything looked ok. I went to a garage to have it looked at. …”

   NHTSA complaint #10405976, filed 2011-06, 84,500 miles

   “I noticed that my 2006 Nissan Titan with 54,000 miles was leaking oil from the right rear axle the other day. I called my Nissan dealer and he told me my warranty ended in january and the rear axle seals would not be covered. The dealership knew all about the problem but would not fix the problem unless I paid 450 dollars. They called it normal wear and tear. They offered even to sell me a new Titan. I declined. I had the problem fixed with a local mechanic for 300 dollars. …”

   Cracked exhaust manifold / exhaust smell

   • 64 complaints (15%)
   • median 85,873 mi at 6.4 yrs old (51 state mileage)
   • 2 mention a crash, fire or injury
   • owner-quoted repair $2,200 (median of 8 quotes)
   • filed 2009–2025

   Owners describe a ticking or clicking noise and an exhaust smell inside the cab, traced by dealers to a cracked or fractured exhaust manifold, sometimes both sides. Complaints mention dealers confirming the crack, and in some cases a failing catalytic converter was found at the same time, with owners paying for the repairs once the warranty was over. Typically reported between about 50,000 and 135,000 miles.

   What to check: Listen for a ticking exhaust leak when the engine is cold and check for exhaust smell in the cab. Ask whether either exhaust manifold or the catalytic converters have been replaced.

   “I think it was in 2009 when I took my vehicle to Nissan to check engine light and light smoke out of exhaust. Ran diagnostic and found out that catalytic converters broke up and broken material went back (suckback) into engine and damaged piston rings which was causing it to smoke. Told me I needed to replace engine cause it was pretty much no good. This truck was 3 yrs. Old at the time. Warranty was out and was and cost me a fortune to replace engine and exhaust system. I had no idea til now how many 2006 Titan owners have had the same issue. …”

   NHTSA complaint #11242423, filed 2019-08, 60,000 miles

   “Catalytic converter failure many Nissan titans are experiencing premature catalytic converter failure. Some failures are causing the engine to seize, as particles of the core of sucked up into the engine. This has caused failures while driving, and as of yet has not caused any crashes or fires. I believe it is an issue that needs to be addressed. There are are large number of failures before 80,000 miles, and a large number of failures right after 80,000 miles which leaves it up to the consumer to pay $1700+ to have the repair done. …”

   Brakes

   ABS, brake shudder, and warning lights

   • 124 complaints (29%)
   • median 53,837 mi at 4.8 yrs old (116 state mileage)
   • 5 mention a crash, fire or injury
   • owner-quoted repair $1,200 (median of 13 quotes)
   • filed 2006–2024

   Owners describe the brake pedal and steering wheel shuddering or vibrating under braking, grinding or crunching sounds, and ABS or brake warning lights coming on. Some say the brakes pull or engage unexpectedly and that a shutdown and restart clears the condition temporarily. Complaints mention a failed brake booster stroke sensor being diagnosed, and several owners said the dealer reported no fault or no fix. Reported from as low as about 12,000 miles up to around 80,000 miles and beyond.

   1 related service bulletin

   What to check: Test the brakes at a few speeds and watch for shudder through the pedal or wheel, and check whether the ABS and brake warning lights come on during a test drive. Ask about ABS sensor or brake booster service history.

   “I purchased the truck in oct 2006. The truck has been back to the dealer four times in less than a year and is going for the fifth time 11/23/07 with brake problems. I was just told by my dealer that there is no fix for the problem I will just have to live with the problem.”

   NHTSA complaint #10209646, filed 2007-11, 7,381 miles

   “Brakes - replaced 3 times within 16000 miles. Would have been more or sooner if I had known how to identify the problem earlier. There are no specific events that lead to the these warranty replacements. I was reassured that my normal driving did not contribute to the problems. Rear axle replacement - 15800 miles. This was also not due to my normal driving, as reassured by the Nissan service station. I was literally shaken off the road. …”

   Rear differential whine, noise, or failure

   • 38 complaints (9%)
   • median 30,000 mi at 2.5 yrs old (35 state mileage)
   • filed 2006–2021

   Owners describe a humming or whining from the rear end from very low mileage, sometimes with gray or low fluid and metal debris, and in some cases a loud snap when starting off or turning. Complaints say dealers replaced the entire rear axle or differential assembly under warranty, often without explaining the cause. Some owners who were past warranty paid for the repair themselves. Reported from as little as a few thousand miles up to around 120,000 miles, with several cases under 15,000 miles.

   What to check: Listen for a whine or hum from the rear while decelerating or coasting and ask for service records showing whether the differential or rear axle assembly was replaced.

   2 excerpts from owner complaints in NHTSA records

   “Ever since I bought my Titan (3-3-06) I noticed a whining noise at speed when I let off of the gas. I always thought it was tire noise. Well on november 15, 2006 I noticed a real bad grinding/whining noise when I decelerated. There was only 6900 miles on the truck. I took the truck to the dealership and a mechanic rode with me up the street and back and said that my truck had problems. I left the truck at the dealership overnight and they replaced the entire rear end. …”

   NHTSA complaint #10174351, filed 2006-11, 6,900 miles

   “Had been hearing a 'clank' when putting vehicle into gear, similar to when a u-joint is failing. While towing my boat trailer (boat was in the water), had the vehicle in 4wd, and turned hard left to exit the parking spot. Heard a loud snap in the rear end, then heard another one. Used truck to pull the boat out, but then disconnected the trailer and had my friend tow the boat home. Took truck to dealership next morning, and they replaced the entire rear axle assembly under warranty (thank god!).”

   Rear leaf spring shackle breaks

   • 28 complaints (7%)
   • median 61,750 mi at 5.3 yrs old (28 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2008–2015

   Owners report the rear leaf spring shackle breaking at the weld, letting the spring punch up through the bed floor, often with a sudden shift in the truck's handling or a lopsided bed. Complaints say the dealers replaced the shackle and sometimes the damaged bed, and several owners say the part was strengthened in later model years. Some owners say they were told the failure was not covered because the truck was bought used. Mostly reported between about 25,000 and 65,000 miles, some while driving or towing.

   2 related service bulletins

   What to check: Inspect the rear leaf spring shackles and their welds for cracks, and look inside the bed floor for dents or fresh repairs. Ask whether a shackle has ever been replaced.

   “I didn't hauled any heavy load in my Nissan Titan 2006 at the time it happened to the broken leaf spring shackle. As I driving I felt the truck have an odd moving motion on the road. I parked the truck and the truck bed seems like its lop-sided when you look straight to the truck bed. I look underneath the truck bed and saw the rear driver side leaf spring shackle broken apart and punctured a large seam to the top of the truck bed.”

   NHTSA complaint #10459758, filed 2012-05, 61,000 miles

   “I have a 2006 Nissan Titan with 31,000 miles on it. The rear bracket that holds the passenger side leaf spring snapped at the bend and sent the entire leaf spring assembly through the floor of my pickup bed. I have contacted Nissan and will be dropping the truck off tomorrow. I have seen numerous complaints of this on the internet. It seems that the original shackle wasn't strong enough for normal driving. Hopefully they will replace the shackle and truck bed.”

Buying note. Evidence on a 2006 Titan should focus on the rear axle seals and differential, the rear leaf spring shackles, and the exhaust manifolds, since these come up repeatedly in owner complaints. Service records showing that any of these parts were already replaced are helpful, and a pre-purchase inspection that includes the underside is worth doing.
