1996 Subaru Legacy Problems

What owners report

Owners of this model year most often write about air bag behavior — both failure to deploy in crashes and unexpected or violent deployment — followed by brake complaints involving warped rotors, a low or soft pedal and long stopping distances. The sample also shows a recurring fuel filler pipe rust-through on older, higher-mileage cars and a cluster of engine misfire and valve guide reports, most of which appear well past 60,000 miles.

1. 1
   Air bags

   Air bag did not deploy, or deployed unexpectedly

   • 21 complaints (17%)
   • median 103,483 mi at 12.9 yrs old (2 state mileage, few)
   • 17 mention a crash, fire or injury
   • filed 1996–2011

   Complaints describe front-end collisions at highway and low speeds in which neither air bag deployed, and a separate pattern of deployment with little or no impact — one at a standstill in a parking-lot bump, one at 5 mph in a rear impact. Several reports mention the passenger-side bag breaking the windshield and sending glass through the cabin when it did fire. Owners generally say the dealer could not explain the behavior or declined to take it up with the manufacturer because of the vehicle's age and mileage. Reported across a wide range of ages and mileages, from near-new cars to examples past 100,000 miles.

   Recall 98V315000

   What to check: Ask whether the air bag system has ever been serviced or diagnosed, and have a shop verify the air bag warning light behaves normally on startup. Note that a recall covers deployment from tow-hook contact with curbs, so confirm whether that repair was done.

   2 excerpts from owner complaints in NHTSA records

   “My 1996 Subaru outback experienced an air bag malfunction on 6/14/2005. While driving down our local highway at 55 MPH the vehicle's air bag suddenly deployed. The sudden deployment caused the vehicle to stall. The vehicle was taken to the dealer but due to the mileage on the vehicle they refused to contact the manufacturer about repairs. The insurance inspector believes that the failure was due to a malfunction in the system because there was no damage to the front end of the vehicle to indicate a 55 MPH crash.”

   NHTSA complaint #10128579, filed 2005-10, 98,966 miles

   “While stopping vehicle idled highly w/no warning. A few minutes later the husband drove because he thought his wife pushed accelerator. Again, vehicle accelerated, resulting in rear end collision w/no air bag deployment. Dealership unable to detect defect.”

2. 2
   Brakes

   Brake pedal low or soft, rotors warped, long stops

   • 12 complaints (10%)
   • median 85,123 mi at 8.9 yrs old (1 states mileage, few)
   • 4 mention a crash, fire or injury
   • filed 1997–2004

   Owners describe a pedal that sinks toward the floor at stops or after the car has sat, pulsation when braking, and stopping distances longer than expected, in a few cases ending in a collision. Front and rear rotors were replaced repeatedly on some cars, with a repair shop quoted as saying the rotors warp and cannot be resurfaced. In other reports the master cylinder was replaced after the pedal went away without warning. Some owners say ABS performance in snow, ice and rain felt poor while the dealer considered the system within specification. Spread from low mileage up to roughly 145,000 miles; several pedal and ABS reports involve wet, snowy or cold conditions.

   1 related service bulletin

   What to check: Test the pedal for firmness at a stop and after the car has sat a while, and check the rotor surfaces for scoring or pulsation on a test drive. A service bulletin describes adding lubrication at the caliper and pad clips to reduce pad drag and uneven wear.

   2 excerpts from owner complaints in NHTSA records

   “The vehicle was slowly moving into driveway and the brakes were applied and failed to stop the vehicle and hit the house. The vehicle was towed. The consumer was informed by dealership that the master cylinder failed. The master cylinder needed to be replaced. The consumer stated that there was no warning. The failure of the master cylinder caused the front brakes rotors and pads to burn up.”

   NHTSA complaint #10091563, filed 2004-09, 85,123 miles

   “Car did not stop in time to prevent crash. Raining. Car in front stopped. Our car going about 25mph. Braked at about 25 yards from other vehicle; crash occured. Is there a requirement that a vehicle stopped within a certain distance at a given speed if properly braked? Thank you. Jonas morris”

   Engine cooling

   Engine misfire and rough running (valve guide wear)

   • 14 complaints (11%)
   • median 75,000 mi at 7.5 yrs old (5 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 1997–2004

   Complaints describe an intermittent miss, shaking and hesitation under acceleration, sometimes severe enough that the car loses power or stalls, often with the check engine light on or blinking. Several owners report repeated repairs with plugs, wires, sensors and coils before a shop identified worn valve guides or a cylinder head problem. Others describe knocking at startup that led to short-block or piston replacement, and one report covers a head gasket failure that stopped the engine. A service bulletin mentions a rubbing mark on the timing belt. Reported from very low mileage up to about 110,000 miles; several owners note the miss is worse when the engine or weather is cold.

   1 related service bulletin

   What to check: On a cold start, listen for ticking or knocking and watch for a rough idle or hesitation on acceleration. Ask for compression or leak-down test results and any history of valve guide or cylinder head work.

   2 excerpts from owner complaints in NHTSA records

   “I have a 1996 Subaru Legacy l with an intermittent engine miss with a p0304 (miss in cylinder 4) code. Most of the time it runs fine but when it misses, it is very violent. It seems to resonate. Changing speed usually makes it go away. When it first started, it only occurred once a month. Over the past year, and after several mechanics visits, it now occurs nearly every trip.I have replaced spark plugs (yes ngk), spark plug wires (Subaru original equipment), gas filter, air filter, coil, pcv valve, knock sensor, cam and crankshaft sensors. …”

   NHTSA complaint #10025205, filed 2003-06, 75,000 miles

   “On august the 12 after going up a steep hill the engine started missing really bad to the point I thought it was going to quit . This problem has been reoccuring every time the car is driven. I contacted my dealer on august the 11 and they had me to bring in the car to decarbon the engine . This didnot stop the problem. Itook the car back to the dealer on sept. 12 to have it decarboned again. …”

   Fuel system

   Fuel filler pipe rusted through and leaking

   Mentioned in 4 of 60 sampled complaints

   Owners report a fuel smell and a puddle of gas under the car while parked or while filling the tank. The cause given in most of these complaints is the fuel filler pipe rusting through, with one owner noting that the stone guard around the pipe traps dirt and blocks the drain so water sits against it. Dealers replaced the filler tube in some cases; in others the owner was told it was not a safety matter and no recall applied. Mostly reported between about 85,000 and 133,000 miles on older cars, often in states that use road salt.

   What to check: Look at the filler pipe and the area behind the stone guard for rust and trapped debris, and check the ground under the tank for fresh stains. Ask whether the filler tube has been replaced.

   “Stone gaurd protecting fuel filler pipe caused dirt to be trapped blocking drain and water to accumulate against filler pipe. Rusted filler pipe causing leaking.”

   NHTSA complaint #10133663, filed 2005-08, 144,000 miles

   “The contact owns a 1996 Subaru Legacy. While filling the gas tank the contact noticed a puddle of gas forming under the vehicle. The filler pipe rusted through and caused thin holes. The current and failure mileages were 110,000.”

   Electrical system

   Charging system and alternator failure

   • 11 complaints (9%)
   • median 53,869 mi at 6.5 yrs old (1 states mileage, few)
   • 1 mention a crash, fire or injury
   • filed 1999–2010

   Owners describe the battery warning light coming on, followed by dimming lights and the engine stalling, with the alternator found at fault. One report notes battery acid leaking and a melted fuse box; another describes a full electrical shutdown the dealer could not explain. Several say the alternator and battery were replaced and the problem came back. Reported mostly between roughly 50,000 and 108,000 miles, with some at unknown mileage.

   What to check: Have the charging voltage checked with the engine running and look for acid residue around the battery and any signs of heat damage near the fuse box. Ask whether the alternator has been replaced and when.

   “While driving engine stalled, lost all power.battery acid was leaking from battery cap. Alternator failed which melted fuse box. Battery lost all charging capacity. Dealer contacted. Over a $1000.00 in repairs.”

   NHTSA complaint #8008581, filed 2002-08, 53,869 miles

   “When car started after having stopped for 3 hours, battery warning light and brake warning light illuminated. Checked brakes/fluid and alternator belt - no problem found. Continued driving; various lights, including check engine light continued to go on and off. Car finally stalled on highway and had to be towed to dealer. Alternator replaced.”

   NHTSA complaint #702504, filed 1999-01

Buying note. These are old cars now, so condition and records matter more than the model itself: have the brakes and charging system checked before purchase and look closely at the fuel filler pipe for rust. Air bag behavior is the hardest item to verify, so an inspection of the system and its warning light is worth the effort.
