full bulletin at NHTSA ↗12 VOLT BATTERY TESTING FOR IN-SERVICE VEHICLES SERVICE INFORMATION The following Service Information lists NNA procedural recommendations for establishing good connections while performing 12V battery testing. These recommendations are expected to promote uniformity during the connection process, therefore reducing the number of incorrect âTest with DCAâ and âReplaceâ results. HINT: If 12 volt batteries are allowed to discharge for a prolonged period of time, battery life may be drastically reduced. This condition may lead to premature battery replacement and customer dissatisfaction. IMPORTANT: ï· CPX-900 is now an accepted testing tool to use along with or in place of the DSS-500

The failure pattern owners describe
The 2009 Nissan Altima electrical system generates two primary failure patterns. The most prevalent involves the electronic steering column lock (ESCL) mechanism, which prevents the vehicle from starting without warning. Owners press the push-button ignition and get nothing—no crank, no accessories. The steering wheel locks, brakes feel stiff, and dashboard warning lights appear (red or amber "key" icon, intelligent key warning). The ESCL failure leaves vehicles immobile in parking lots, gas stations, and shopping centers. One owner reported being stranded 35 miles from home; another was stuck in below-freezing temperatures waiting for a tow. A dealership service advisor told one complainant she had seen many 2009 Altimas with this failure.
The second pattern involves the brake light switch (part 25320-AX00C), which fails prematurely and prevents the push-button start from recognizing brake pedal depression. Some owners report the part failing again after replacement, with evidence of burning or internal connector damage. One owner replaced the switch three times.
A third, less common electrical issue involves rapid battery discharge when parked. One owner's battery drained completely in 10 hours despite the automatic headlight shutoff, freezing the vehicle in park and disabling the trunk release.
Additional reports cite steering wheel control switches acting erratically (triggering the horn instead of audio controls) and dashboard indicators switching between display modes on their own. One crash involved sudden unintended acceleration during a low-speed turn and airbag non-deployment, which an owner suspects resulted from a pinched wiring harness affecting the CVT sensor inputs.
Nissan extended the ESCL warranty to 6 years from purchase date but did not notify most owners by mail. When the extended warranty expired (usually around 2015–2016), Nissan denied reimbursement requests, leaving owners responsible for repair costs between $725 and $1,411.

Failure modes owners describe
Electronic Steering Column Lock (ESCL) Failure
The ESCL mechanism malfunctions and prevents the vehicle from starting. The system fails to recognize the key fob or allow ignition, rendering the vehicle immobile and potentially stranding the driver.
When: Varies; one owner at 25,290 miles; another at 63,200 miles; another at 80,000 miles; another at 97,000 miles. Most failures occur between 2014–2016, often after 60,000+ miles.
Symptoms owners cite: Vehicle will not start despite key fob recognition (doors lock/unlock normally); Push-button start unresponsive, only shows 'LOCK' or 'ACC' mode; Steering wheel locks in place; Brake pedal feels stiff or unresponsive; Red or amber 'key' warning light on dash; intelligent key warning light illuminated; No crank or engine attempt; Part occasionally fails intermittently, then works again temporarily
Codes mentioned: ESCL system malfunction, Electronic steering lock module failure, Part 48700-JF00A, Intelligent key system failure
Repairs/costs cited: Replacement of ESCL unit costs $725–$1,411. Parts frequently on backorder. One owner reported mechanic advised the part is 'so faulty that it will go out again in time.' Nissan changed the lock mechanism on 2010+ models but did not retrofit earlier vehicles.
Recalls/TSBs owners mention: Nissan extended the factory warranty to 6 years from purchase date for ESCL failures (later tightened to specific VIN ranges). Extended warranty expired for most vehicles by mid-2015. Nissan did not send recall notices to owners; most learned of the extended warranty through online research or when visiting dealers for service. Nissan Consumer Affairs denied reimbursement requests after warranty expiration, citing that vehicles were 'too old' or had 'too many miles.' A voluntary recall campaign was launched in 2013 (referenced in complaint #1), but coverage was inconsistent and did not reach all affected VINs. One owner received a 2020 recall notice but was turned away at the dealership and charged $900 out of pocket when the part failed in 2021.
Brake Light Switch Failure (Keyless Start Incompatibility)
The brake light switch (part 25320-AX00C) fails to recognize brake pedal depression, preventing the push-button ignition from engaging the starter. This is a critical component for keyless start operation.
When: One owner reported failures at under 23,000 miles. Replacements were done in June 2015 and August 2016, with recurrence. Another failure occurred at approximately the same point in ownership on a different vehicle.
Symptoms owners cite: Push-button start unresponsive even when brake pedal is depressed; 'PUSH BRAKE' warning light remains illuminated on dash; Ignition only goes to 'ACC' mode, not 'START'; Intermittent start failures that resolve temporarily; Burning smell near brake pedal area; Internal connector corrosion or evidence of heat damage inside the switch
Codes mentioned: Brake light switch failure, Part 25320-AX00C, Nissan Service Bulletin NTB10-139
Repairs/costs cited: Part costs vary; one owner paid $127–$173 for replacement plus labor. A second replacement with the same part showed internal connector corrosion and heat damage; owner opened the part and found connectors 'frozen to the contacts' with evidence of electrical flash or burning. Third replacement with aftermarket part resolved the smell and start issues. One owner reported having to replace the switch three times since the vehicle was new.
Recalls/TSBs owners mention: Nissan issued Service Bulletin NTB10-139 acknowledging the brake ignition switch defect. Nissan Corporate has refused reimbursement even for customers offering to pay labor separately. No recall issued.
Rapid Battery Discharge When Parked
The vehicle's electrical system drains the battery at an abnormally fast rate when the engine is off, despite the automatic headlight shutoff feature being functional. The battery becomes completely depleted in a matter of hours.
When: One owner reported failure within 3 weeks of purchase (vehicle purchased Dec. 7, 2008; battery dead Jan. 23, 2009). Battery failure occurred after approximately 10 hours of parking.
Symptoms owners cite: Battery completely dead after a short parking period (10 hours); Keyless entry does not work; Push-button start does not respond; Vehicle frozen in park; shift lever will not move; Trunk cannot be opened via switch on dash or trunk button; Radio loses programming after jump-start (requires full reprogramming of time and stations); Vehicle can roll away if shut off in neutral due to power loss
Codes mentioned: Electrical discharge design flaw, Battery drain with ignition off
Repairs/costs cited: AAA jump-started the vehicle; it ran normally for 3 days after. No permanent repair documented. Owner expressed concern that safety systems relying on battery power (brake hold, shift lock, airbag deployment) could fail if battery dies during operation.
Steering Wheel Control Switch Malfunction
The steering wheel-mounted audio/cruise control switches send incorrect electrical signals, causing unintended activation of horn, dashboard indicators to shift modes randomly, and MPG display to flicker between analog and digital formats.
When: One owner reported audio control switch acting up approximately 1 month before a sudden acceleration event. Issue was intermittent and recurred during collision center testing.
Symptoms owners cite: Audio control buttons trigger horn instead of volume/track control; MPG indicator switches between bar graph and digital display without driver input; Switches work normally intermittently, then malfunction again
Recalls/TSBs owners mention: One collision center technician mentioned a 'pinched harness' as a possible cause during post-accident investigation.
Sudden Unintended Acceleration with Non-Deploying Airbag
During a low-speed parking lot turn with brakes applied, the vehicle suddenly accelerated to full throttle, was uncontrollable, and collided with a wall. The airbag did not deploy despite impact exceeding 15 mph. Owner attributes the failure to a cascade of electrical system problems.
When: Approximately 25,290 miles (approximately 2 years of normal usage after purchase)
Symptoms owners cite: Brakes initially unresponsive to moderate pedal pressure; Loud revving; throttle opened to full without pedal input; Vehicle accelerated approximately 1.5–2 car lengths before impact; Airbag failed to deploy despite collision impact; Steering wheel control switches had malfunctioned 1 month prior (horn honking instead of audio control); Dashboard MPG indicator was switching between display modes involuntarily; Owner sustained knee laceration from steering column and head impact
Codes mentioned: CVT sensor failure (suspected by owner), Pinched wiring harness (suggested by Nissan technician)
Recalls/TSBs owners mention: Nissan technician mentioned a pinched harness as a possibility but did not perform a complete electrical system investigation or recall any related components.
Battery Terminal Corrosion and Venting
The vehicle battery vents excess gas that should condense within the battery compartment. Instead, the gas causes heavy corrosion on the positive terminal and cable. Corrosion reaccumulates rapidly even after replacement.
When: Original battery developed heavy corrosion around positive terminal. After dealer replacement, heavy corrosion reaccumulated within 3 months. Owner noted similar issues reported by other Altima owners.
Symptoms owners cite: Heavy white/blue corrosion buildup on positive battery terminal; Battery failure requiring replacement; Corrosion reaccumulates within 3 months of replacement; Cable must be replaced along with battery
Repairs/costs cited: Dealer replaced battery. Subsequently, positive terminal and cable required replacement due to heavy corrosion. Dealership acknowledged that harness and cable should have been replaced with the original battery but were not recommended.
Recalls/TSBs owners mention: Dealership stated that batteries 'routinely vent excess gas' but did not explain why this design issue was not corrected or why the harness/cable were not proactively replaced.
Power Door Lock Actuator Failure (All Four Doors)
All four power door lock actuators failed simultaneously or sequentially over 1–2 weeks, preventing doors from locking or unlocking via remote or dashboard button. Manual mechanical locking/unlocking remains functional.
When: September 2014. Vehicle had no accident or exposure to water/fire. Failure occurred over 1–2 week period.
Symptoms owners cite: Front and rear passenger doors stop responding to remote or power lock button; Driver side doors follow over next 1–2 weeks; All four doors ultimately unresponsive to keyless entry remote and power button; Manual mechanical locks still functional
Repairs/costs cited: Quoted repair cost $250 per door. Owner did not pursue repairs due to cost. Locks remain unresponsive 9–10 months later.
Passenger Occupant Sensor Failure
The passenger seat occupant airbag sensor fails, causing the amber passenger occupant warning light to remain illuminated on the dashboard and the airbag control panel to show a red flashing airbag light.
When: Failure occurred without prior warning or incident.
Symptoms owners cite: Amber passenger occupant warning light permanently illuminated; Red flashing airbag light on control panel; Sensor does not detect occupant even when appropriate-sized adult is seated; Vehicle has never been in an accident
Codes mentioned: Passenger seat occupant airbag sensor failure
Repairs/costs cited: Dealership quoted $2,400+ for passenger seat replacement. Owner unable to pay; seeking recall or technical bulletin.
Recalls/TSBs owners mention: Owner notes that other model years of the same make and model were fixed by manufacturer at no cost and is hoping for similar treatment.
