"Service bulletin - American Honda is announcing a powertrain warranty extension as a result of a settlement of a class action captioned, Soto et al.v. American Honda Motor Co., Inc., Case No. 3:12-cv-1377-SI (N.D. Cal.). The piston rings on certain cylinders may rotate and align, which can lead to spark plug fouling. This can set DTCs P0301 No. 1 cylinder misfire detected, P0302 No. 2 cylinder misfire detected, P0303 No. 3 cylinder misfire detected, P0304 No. 4 cylinder misfire detected, and cause the MIL to come on.

Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
HONDA: SPARK PLUGS MAY BE FOULED. THE MALFUNCTION LIGHT COMES ON WITH STORED TROUBLE LIGHTS.

The failure pattern owners describe
The 2010 Crosstour's 3.5L V6 shows a clear pattern of excessive oil burn and secondary ignition failure. Owners consistently report consumption of 1 quart per 1,500–2,500 miles despite regular oil changes and on-time maintenance. This isn't normal; one mechanic told an owner "oil doesn't disappear from the vehicle." Some drivers caught their car bone-dry between services—risking catastrophic engine damage.
The heavy oil consumption dirties spark plugs faster than normal, causing cylinder misfires (usually #3, #1, or #4). Check engine light comes on, the engine runs rough, and power drops. Owners replace the fouled plugs, but they re-oil within months. Dealerships have applied software updates and oil pressure switch replacements with inconsistent results. Honda issued TSB 13-079 addressing piston ring wear and TSB 11-033 for the misfire chain, and a class-action lawsuit is in motion—some owners report being offered piston ring replacement under extended warranty. One dealership refused to acknowledge the consumption as a defect, telling the owner it's normal to top off between changes. Owners also report stalling at highway speed (dealership-attributed to software) and oil pressure sensor faults that recur within days of service. The net risk: unattended oil level leads to seized engine, and recurring misfire issues plague long-term ownership despite multiple trips to the dealer.
Failure modes owners describe
Excessive oil consumption
Engine consumes more oil than normal between service intervals. Owners report consumption rates of 1 quart per 1,500–2,500 miles, requiring regular top-offs between scheduled oil changes. Some owners state they add oil regularly despite keeping up with service intervals.
When: Observed from early ownership (some within months of purchase) through high mileage (135,000+ miles); affects both newer and older examples in the cluster.
Symptoms owners cite: Oil level drops rapidly between changes; Frequent need to add oil between scheduled services; No obvious external leaks
Repairs/costs cited: Honda service procedures include formal oil consumption test (monitored over multiple oil change cycles). One owner reports dealership stated excessive oil consumption is 'normal' and does not warrant service. Some owners mention engine can run dry if consumption goes unnoticed, leading to secondary damage.
Recalls/TSBs owners mention: Honda TSB 13-079 addresses ring wear (re-ring service). One owner received 8-year extension warranty (unlimited miles) for this problem only, suggesting class-action involvement. Dealership response inconsistent: some acknowledge and test, others dismiss as normal.
Cylinder misfire from oil-fouled spark plugs
Oil coating builds up on spark plugs, causing ignition failure in individual cylinders. Check engine light illuminates (often flashing), engine runs rough, and power output drops. Occurs recurrently even after spark plug replacement.
When: Reported across the ownership timeline; one case at 135,000 miles, others recurring within months to a few years of initial complaint.
Symptoms owners cite: Check engine light on or flashing; Engine runs rough or hesitates under acceleration; Abnormal engine noise; Reduced power / sluggish acceleration; Idle roughness or fluctuation; Spark plugs visibly oil-fouled or saturated on inspection
Codes mentioned: P0303 (cylinder 3 misfire), P0301 (cylinder 1 misfire, implied), P3400 (Bank 1 pressure switch), P3497 (Bank 2 pressure switch)
Repairs/costs cited: Spark plug replacement alone does not resolve the problem permanently; plugs re-foul within months. One owner replaced cylinder 4 spark plug three separate times over 4–5 months with no lasting fix. Some dealers recommend software update and/or rocker arm oil pressure switch replacement. One owner reports piston ring replacement (upper engine rebuild) recommended under warranty claim.
Recalls/TSBs owners mention: Honda TSB 11-033 and TSB 13-078 address this issue. Software updates offered. One dealership replaced rocker arm oil pressure switch and performed software update, with limited success. Another applied engine software update and promised upper-engine rebuild if failure recurred (8-year warranty). Class-action lawsuit referenced in complaints.
Engine stalling or loss of power at highway speed
Engine cuts out or loses power while driving at highway speed, requiring vehicle to be stopped and restarted. Dealership attribute to software issue.
When: At least one occurrence on freeway at highway speed.
Symptoms owners cite: Engine cuts out while driving; Loss of all power / unable to accelerate; Requires stopping and waiting to restart
Repairs/costs cited: Dealership described as 'known software problem.' One prior occurrence blamed on a sensor replacement.
Recalls/TSBs owners mention: Dealership stated this is a known software issue but no recall issued per complaint.
Oil pressure switch malfunction
Oil pressure switches (front and rear rocker arm) report false or stuck conditions, triggering check engine light and preventing proper engine operation.
When: Multiple occurrences within the same owner's experience, recurring within days to weeks.
Symptoms owners cite: Check engine light on; Eco mode will not function; Engine light comes on repeatedly even after service
Codes mentioned: P3400 (Bank 1 pressure switch), P3497 (Bank 2 pressure switch)
Repairs/costs cited: Rear rocker arm oil pressure switch replaced; front rocker arm oil pressure switch later diagnosed as faulty. Problem recurred within days of service. One owner notes Honda service bulletin covers this as a computer and oil pressure monitor issue.
Recalls/TSBs owners mention: Honda TSB addresses this. Service covered, but recurring failures within short timeframes suggest underlying design or calibration issue.
Engine will not start or restart
Vehicle stops driving in the middle of the road with no restart attempt. Loud noise heard, but cause undiagnosed despite dealer evaluation.
When: On roadway during normal operation.
Symptoms owners cite: Vehicle stops suddenly; Loud power sound prior to stall; Will not crank or start
Repairs/costs cited: No diagnosis made despite dealer evaluation.

Engine cut out at highway speed on freeway. Would only restart after coming to a stop and waiting a few minutes then retrying. This has happened previously after which dealer changed a sensor, this time dealer said this was a known software problem. Surely there should be a recall loosing all power on the freeway could be deadly. *tr
Excessive oil consumption observed with Honda crosstour 2010. Since the car was purchased new, the car consumed 1 quart of 0w20 engine oil per 2500 miles. This is a safety issue, since not all drivers pay close attention to engine oil level. Driving with insufficient engine oil level could cause potential engine failure while driving. I have contacted american Honda motor co. And log a case# to…
The vehicle will use about a quart of oil every 1500 miles. The number 3 cylinder plug will become fouled and case the engine to run rough and engine light flashes. This is under Honda tsb 11-033
Have been advised the eco system is causing oil to leak out into the engine cause oil build-up and other issues.
