I was driving home from work on a very busy street, driving about 55 miles an hour. It was dark and raining and my car completely shut down! No headlights, no dashboard lights and nothing was running...it completely shut off no hazard lights either! Luckily I was able to pull off to the side. I pulled my key out of the ignition, then put it back in and nothing happened. I repeated putting my key…

What stands out
Of the 6 model years of Acura TL we track for electrical problems, this one carries the most owner complaints on file — 27.
Owners have filed 27 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
The failure pattern owners describe
Buyer takeaway: The 2006 Acura TL has a well-documented Hands-Free Link Bluetooth module that drains the battery, potentially leaving you stranded after just a couple of days without driving. Expect to replace batteries frequently or disconnect the HFL entirely; the dashboard may also crack around the passenger airbag, and multiple owners report undiagnosed electrical problems and complete shutdowns while driving.
The standout issue is the Hands-Free Link Bluetooth module draining the battery continuously, even when the vehicle sits unused. Owners go through 5–6 batteries in a few years, or one every 18 months. The car won't start after sitting 2–3 days without driving; some report battery drain overnight. The HFL sits above the rearview mirror and overheats in sunlight—owners describe it as too hot to touch. Acura dealerships suggest disconnecting the HFL fuse (costing $100–$400) or replacing the entire module ($400–$700), but the manufacturer stopped making the part and won't recall it.
The dashboard cracks around the passenger-side airbag, sometimes splitting from the windshield down to the seat. Cracks widen on hot days, and owners can see bolts or hinges beneath them, raising concerns about airbag function.
Multiple owners also report complete electrical shutdown while driving—all lights and power suddenly cut out at highway speed, forcing them to pull over. Interior lights and dashboard displays quit independently. One owner's vehicle caught fire; Acura refused to investigate it as a defect.
Several owners replaced batteries, alternators, and starters trying to pinpoint the electrical problem, only to discover the HFL was the culprit. Disconnecting it fixed the drain, but owners lose the Bluetooth feature and are stuck with expensive, out-of-warranty repairs.

Failure modes owners describe
Hands-Free Link (HFL) Bluetooth Module—Battery Drain
The HFL Bluetooth module draws power continuously from the battery even when the vehicle is off, causing premature battery discharge. Owners report the module heats up excessively when exposed to sunlight (mounted above the rearview mirror) and eventually fails or continues to drain the battery. Replacing the battery does not resolve the issue; disconnecting the HFL is the typical workaround dealers suggest.
When: Occurs after 10+ hours of non-use or immediately after starting. Battery drain becomes critical within 2–3 days of non-operation; some owners experience drain overnight.
Symptoms owners cite: Battery dead after 2–3 days without driving; Car will not start after sitting overnight; Slow starting even with a new battery; Multiple dead batteries over short periods (owners report 5–6 batteries in 4 years, or one per 18 months); HFL module gets very hot or becomes too hot to touch; Intermittent starting failures that worsen progressively
Repairs/costs cited: Dealers charge $100–$400 to disconnect the HFL fuse; replacement of the full unit costs $400–$700. Some owners report dealers are unwilling to cover replacement under warranty. Owners cite that the problem is widespread and Acura knows about it but refuses to recall or fix it. Trickle chargers recommended as a long-term workaround.
Recalls/TSBs owners mention: Acura customer care stated they stopped making the replacement part and that parts are only required to be available for 10 years. Dealerships typically suggest disconnecting the module as the fix. No formal recall issued.
Dashboard Cracking Around Passenger-Side Airbag
The dashboard cracks and splits, particularly on the passenger side around the airbag area. Cracks run from the windshield to the passenger seat and widen further on hot days. Owners can see the hinges or bolts behind the cracks, raising concerns about airbag deployment safety and integrity.
When: Cracks develop within 3–6 years of ownership; they widen noticeably on hot days.
Symptoms owners cite: Spider cracks on dashboard in front of passenger seat; Cracks widening on hot days; Visible hinges or bolts through the cracks; Cracks appearing on both sides of the airbag cover
Repairs/costs cited: Dealers have assured owners the cracks are safe and the airbags will deploy correctly, but owners report this assessment is unverified. No repair or replacement cost information provided in narratives.
Recalls/TSBs owners mention: Dealers have inspected and assured owners it is safe, but no formal repair program or recall has been issued.
Complete Electrical Shutdown While Driving
The vehicle loses all electrical power while in motion—headlights, dashboard lights, and all systems shut down. The car does not respond to key ignition attempts until several minutes later. In one case, the vehicle completely shut off at 55 mph in rainy conditions on a busy street.
When: Reported at various mileages; one owner with recent battery replacement experienced shutdown at highway speed.
Symptoms owners cite: All lights (headlights, dashboard, hazard) go out while driving; Vehicle stops responding to ignition; Keys must be removed and reinserted multiple times before vehicle restarts; After restart, vehicle may not start again for hours or until next morning
Repairs/costs cited: No repairs attempted by owners in the narratives; cause was not identified.
Navigation System and Dashboard Display Failure
The navigation system stops responding or gets stuck in a rebooting loop. When the HFL battery-drain problem triggers a battery replacement, the radio and navigation systems lose synchronization, causing the navigation voice to stop working and the clock to become un-adjustable. One owner reports the navigation system has a DVD-based system with read errors.
When: Navigation fails independently within 3–5 years; display issues typically follow HFL battery drain and battery replacement.
Symptoms owners cite: Navigation system stuck on 'rebooting' screen; Navigation voice stops working even though the radio still functions; Dashboard display shows a black rectangle or fails to display information; Clock cannot be reset; Radio and navigation no longer communicate
Repairs/costs cited: One dealer suggested replacing a CD to update the system; full system replacement cost approximately $500. Owners report dealers said they don't know the cause.
Interior Light Failures
Multiple interior lights, including dashboard warning lights and panel illumination, stop working. Owners report most of the inside lights go dark, particularly the dash lights controlling radio and air conditioning.
When: Occurs concurrently with battery-drain issues and electrical failures; no specific mileage provided.
Symptoms owners cite: Dashboard lights go out; Radio/HVAC control lights inoperative; Interior cabin lights stop working
Repairs/costs cited: One owner replaced the alternator, battery, and starter trying to resolve the problem, with no success.
Engine Fire
One vehicle caught fire while the owner was driving through a McDonald's drive-through at low speed. Smoke came from under the hood; the fire grew rapidly despite the owner's attempt to extinguish it with a jacket. The fire department arrived and extinguished the fire completely.
When: November 9, 2007, at approximately 10:00 PM CST.
Symptoms owners cite: Smoke under the hood while driving at low speed; Fire ignition and rapid spread
Recalls/TSBs owners mention: Acura refused to accept the fire as a potential defect in the vehicle.
Windshield Wiper and Washer Fluid Inoperative
Windshield wipers and washer fluid dispensers stop functioning. Works neither when parked nor while in motion.
When: Not specified in narrative.
Symptoms owners cite: Windshield wipers will not operate; Washer fluid will not dispense
Automatic Headlight Sensor Failure
The automatic headlight light-sensor system is damaged or non-functional.
When: Not specified in narrative.
Symptoms owners cite: Automatic headlight sensor does not engage
