When I am going in a speed range about 35 MPH I get like shudder/grinding sound coming out of the bottom of the pilot. I am getting very concern because I've driven other pilots and they all do the same and they shouldn't be doing this noise. *js

The failure pattern owners describe
Buyer takeaway: The 2005 Honda Pilot has two major powertrain issues: transmission cooling lines frequently fail and allow coolant and transmission fluid to mix, causing sudden loss of power and requiring $2,500–$6,400 in repairs; separately, the transmission exhibits shuddering at 30–40 mph starting around 50,000 miles and progresses to complete failure, often requiring full transmission replacement at $4,000+. Both defects appear widespread, Honda has not recalled them despite acknowledging the problems are common, and rebuilt transmissions often fail again.
The 2005 Honda Pilot's powertrain is plagued by two distinct failure patterns that owners describe as design flaws rather than isolated defects.
Radiator/Transmission Cooler Failure. The transmission cooling line or cooler inside the radiator fails without warning—sometimes disconnecting, sometimes rupturing internally—allowing transmission fluid and engine coolant to mix. Owners report sudden loss of power, overheating, smoke from under the hood, transmission slippage, and complete immobilization. One owner was stranded 30+ minutes in rural Maine with young children; another experienced loss of power on a highway while driving a family of four. Repair costs range from $825 to $6,400, involving radiator replacement, multiple transmission flushes (one shop used 28 quarts), and often complete transmission replacement. Even after repair, coolant contamination can damage internal transmission clutches, and rebuilt transmissions fail again within thousands of miles. Dealers admit they see this "a lot" and "very frequently." The 2003–2004 Pilot was recalled for the same issue; the 2005 was not, though the Acura MDX (same powertrain) received a service bulletin allowing goodwill repairs out of warranty.
Torque Converter Shudder. Starting between 50,000 and 100,000 miles, vehicles exhibit violent shuddering at 30–50 mph under light acceleration. Owners initially suspect worn tires and replace them to no avail. The shudder worsens over time and can make the vehicle feel unsafe. Dealers confirm it is a transmission design defect and quote $4,000–$5,000 for torque converter replacement or full transmission replacement. Some owners were denied warranty coverage after extended warranty expired despite reporting the symptom beforehand. One owner found over 300 online complaints; another noted Honda "corrected" the design in 2006 models, proving awareness of the defect.
Both failures carry safety implications. A blinking 'D' light warns of pressure switch failure or deeper transmission damage, requiring replacement. Owners consistently report Honda's refusal to recall or provide financial assistance despite widespread acknowledgment of these defects.

Failure modes owners describe
Transmission Cooling Line / Radiator Transmission Cooler Failure
The transmission cooling line or transmission cooler located in the radiator disconnects, fails, or ruptures. This allows transmission fluid and engine coolant to mix, contaminating both systems. The coolant entering the transmission damages internal clutch surfaces and causes transmission failure. Owners report sudden loss of power, inability to maintain speed, high engine RPMs, transmission slippage, overheating, and vehicle immobilization.
When: Between 55,000 and 145,000 miles; some occur very early (4 miles parked) or suddenly after 15 minutes of driving; failures reported in vehicles ranging from recent use to established 10+ year ownership
Symptoms owners cite: Loss of power and inability to accelerate; Engine strain and smoke from under hood; Transmission fluid level depleted / extremely low; Brown oily liquid draining from engine area; Blue oily fluid following brown leak; Milky red transmission fluid (coolant mixed in); Temperature warning light illumination; Transmission slippage or refusal to engage gears; Vehicle unable to climb hills or maintain speed; Overheating; High RPMs with no acceleration response
Codes mentioned: P0872
Repairs/costs cited: Radiator replacement ($400–$825), transmission fluid and coolant flushes (multiple flushes: 6–28 quarts reported), transmission replacement or rebuild ($2,500–$6,400 total repair cost including parts and labor), hose replacement, thermostat replacement, engine flushing. Some owners report rebuild transmissions fail again after thousands of miles.
Recalls/TSBs owners mention: No recall issued. Dealer service departments acknowledge the problem is common and see it frequently. 2003–2004 Pilots were recalled for the same issue; 2005 models were not. Acura MDX (same powertrain as Pilot) issued Service Bulletin 06-003 and offered goodwill consideration for out-of-warranty coverage; Honda did not extend same to Pilot. Honda refuses warranty coverage citing age/mileage, denies transmission cooler failure is part of transmission unit. Owners report Honda has been made aware via internet complaints and NHTSA filings but refuses to recall or provide financial assistance.
Torque Converter Shudder / Transmission Vibration at 30–50 MPH
Vehicle exhibits pronounced shuddering, vibration, or shimmering sensation when accelerating at low to moderate speeds (typically 25–50 mph, most common 30–40 mph). The vibration is felt throughout the vehicle body and is worse under light throttle but stops when accelerator is pressed harder or when shifted to D3. Symptoms worsen over time and mileage. Owners often initially suspect tire imbalance or alignment issues but diagnosis confirms torque converter or transmission design defect.
When: Typically begins between 50,000 and 100,000 miles; has been observed as low as 50,000 miles and persists or worsens through 170,000+ miles; can occur intermittently at first then become constant
Symptoms owners cite: Shuddering or vibration between 30–50 mph (most common 35–40 mph); Vibration felt in vehicle body, not steering; Shudder stops when accelerating harder or shifting to D3; Symptom occurs whether engine is cold or warm; Whole vehicle shakes and becomes hesitant when shifting gears uphill; Instability when vehicle shakes during transmission shifts; Fear of transmission failure during normal driving
Repairs/costs cited: Torque converter replacement ($2,000–$5,000) or complete transmission replacement ($4,000–$11,000). Tire balancing, alignment, and rotation do not resolve the issue. Dealers informed owners that transmission design cannot support vehicle weight. Acura MDX issued TSB 06-003 for torque converter replacement; Honda Pilot owners must pay out of pocket or negotiate goodwill coverage (one owner reported 75% Honda coverage). Rebuilt transmissions reported to fail again.
Recalls/TSBs owners mention: Honda acknowledges problem informally via dealers stating it is 'very popular with Honda Pilots' and 'common.' Acura issued TSB 06-003 for MDX (same powertrain) allowing goodwill replacement even out of warranty; Honda has not issued equivalent recall or TSB for Pilot despite identical powertrain. Honda design corrected in 2006 model year. No formal recall issued for 2005 model. Owners report Honda refused to help despite website complaints numbering in hundreds.
Blinking 'D' Gear Indicator Light / Transmission Warning Light
Transmission 'D' (Drive) indicator light on dashboard blinks continuously while driving, then stops when vehicle is turned off and restarted. Light may reappear after driving for several minutes or miles. Blinking can be intermittent (appearing and disappearing over weeks) or persistent. Indicates a transmission electronic or mechanical fault that may lead to transmission damage if not addressed.
When: Occurs between 62,000 and 107,000 miles; can appear suddenly or intermittently over extended periods
Symptoms owners cite: Continuous blinking of 'D' indicator light on dashboard while driving; Light stops blinking when vehicle is turned off and back on; Light reappears after driving for a few minutes; Intermittent blinking pattern; No engine warning light illuminated (in some cases)
Codes mentioned: P0872
Repairs/costs cited: Replacement of 4th gear pressure switch ($34–$40 part cost; dealer charges $350 for $34–$40 part plus labor). Transmission flush recommended. Switch replacement may be temporary fix if internal transmission damage has begun.
Recalls/TSBs owners mention: Dealers acknowledge this is a 'very popular' problem with Honda Pilots. Part is recognized as defective by dealer technicians. No recall issued. Diagnostic code P0872 (Transmission Fluid Pressure Low) points to pressure switch but may indicate deeper internal transmission issues.
Transmission Slippage and Refusal to Engage
While driving, transmission slips out of gear or refuses to shift into Drive. Vehicle loses power mid-drive, with high RPMs but no acceleration response. In some cases, transmission will not engage at all when attempting to shift into Drive from Park. Some owners experience repeated shift failures requiring multiple restarts to re-engage.
When: Occurs between 70,000 and 145,000 miles; can happen suddenly after vehicle has been running normally
Symptoms owners cite: Transmission slips out of gear during acceleration; No response to accelerator (high RPMs, no speed increase); Refusal to shift into Drive gear; Vehicle must be shifted to Neutral and back to Drive to regain engagement; Repeated slipping and re-engagement; Vehicle speed drops suddenly despite throttle input
Repairs/costs cited: Transmission fluid flushing (multiple flushes), radiator and hose replacement, full transmission replacement or rebuild. Costs range $1,000–$6,400. Fluid contamination (coolant in transmission) is often the underlying cause.
Recalls/TSBs owners mention: No recall. Dealers diagnose and repair but do not acknowledge design defect. Some attribute problem to coolant/transmission fluid mixing from radiator failure.
ABS Engagement Noise / Brake Grab Sensation
Owner reports loud grabbing or clutching noise when braking or under specific road conditions (wet roads, uneven surfaces). Noise is startling and sounds like brakes are being forcefully applied or transmission issue. Honda service manager was able to replicate the noise by applying brakes with one side of vehicle wheels on pavement and other side on grass, determining it was ABS system engaging. Issue described as intermittent.
When: Reported at low speeds (20–30 mph) on wet roads; intermittent occurrences
Symptoms owners cite: Loud grabbing or clutching noise when braking; Noise startles driver; Sound lasts 1–2 seconds; Occurs on wet roads; Noise resembles transmission or rear-end issue; ABS system engagement confirmed by dealer
Repairs/costs cited: Identified as normal ABS system operation in certain conditions (wet surface, uneven wheels on pavement vs. grass). No repair required; issue is normal ABS behavior rather than a defect.
Recalls/TSBs owners mention: Honda service manager diagnosed and explained as normal ABS engagement in specific conditions. No recall or repair needed; customer satisfied with explanation.
