2001 Saab 9-5 Problems

What owners report

Owners of the 2001 Saab 9-5 most often describe sudden loss of engine power while driving, which many complaints trace to the direct ignition cassette (also called the ignition discharge module). Fuel line and fuel pump connection leaks are the second recurring theme, followed by cooling and electrical accessory problems. Reports cluster from roughly 20,000 to 120,000 miles, and many describe the stall as arriving with no warning at all.

   Electrical system

   Sudden engine stall from ignition cassette (DIC/IDM) failure

   • 42 complaints (40%)
   • median 61,726 mi at 4.8 yrs old (36 state mileage)
   • 5 mention a crash, fire or injury
   • owner-quoted repair $677 (median of 7 quotes)
   • filed 2001–2014

   Owners describe the engine quitting without warning at highway or in-town speeds, sometimes dropping to limp-along power with a flashing check engine light, shaking, or a burning smell and smoke from under the hood. Many say the car would not restart or only restarted after cooling down. Complaints frequently mention the direct ignition cassette or ignition discharge module being replaced, and several owners note that the catalytic converter was also replaced afterward. Mostly reported between about 21,000 and 120,000 miles, with many clustered in the 30,000-70,000 mile range and no clear seasonal pattern.

   Recall 05V399000

   What to check: Ask whether the ignition cassette has been replaced and whether the car's VIN was covered by the ignition module campaign. A scan tool check for stored misfire or ignition codes, plus a test drive from cold, is worthwhile.

   “The engine on our 2001 Saab 9.5 wagon completely shut down as we exited I-10 north of san antonio texas. The vehicle was at a speed of 65 MPH and the engine just quit. We were able to stop the car at the exits intersection because of its length of about 1/4 mile. There was no warning, just no engine and no restart. The direct ignition cassette was replaced.”

   NHTSA complaint #10025942, filed 2003-07, 23,400 miles

   “Add my 2001 Saab 9-5 wagon, 6 cyl, to the list of those with di cassette failure. Traveling at about 50 MPH on a beautiful june morning the engine suddenly lost power. When I pulled off the road, a puff of smoke came from under the hood and there was a distinct burnt electrical smell when I raised the hood. My mechanic believes the faulty di cassette may have been the cause for the 2 previous catalytic converter failures. …”

   Fuel system

   Fuel leaks at pump lines and retaining clip

   • 12 complaints (12%)
   • median 56,000 mi at 5.5 yrs old (9 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2002–2011

   Owners describe gasoline pouring or spraying from the fuel pump area, a strong fuel smell, and the tank draining rapidly, sometimes while driving. Several complaints say the fuel line came loose from the pump because a retaining clip or tab failed, and that a dealer repaired it with a new line or securing bracket. Some owners report repeated occurrences, and a few mention the repair area still smelled of fuel afterward. Reported from roughly 32,000 to 137,500 miles, in a mix of everyday driving conditions.

   Recall 07V087000

   What to check: Ask whether the fuel pump line retaining recall work was done on this VIN. Check for a fuel smell around the rear seat and under the car after refueling, and look for any signs of weeping at the pump fittings.

   “We own a 2001 Saab 9.5 2.3t. My wife is a commuter user of the car and car has very low mileage. Her gas tank has lost the coupling to the fuel tank twice and lost all the gas on the road. She was stranded both times. This is completely inexplicable and the dealership has never answered why this has happened. Due to safety concerns, we felt it appropriate to report. We will have to confirm the incident dates in our records.”

   NHTSA complaint #10181925, filed 2007-02, 32,000 miles

   “Gasoline leak - I was driving with my two small children in the car (2001 Saab 9-5 wagon (4-cylinder) when someone pulled up beside me to tell me that gas was pouring our of my car. I stopped the car and the remainder of the tank emptied on the ground. Once the fire chief okay'ed the car for transport, (this was required by the towing company.) I had the car towed to the dealership. The dealership indicated that the clip for the fuel line had come undone and that the fuel line had come loose. …”

   Engine cooling

   Cooling system and oil light warnings

   Mentioned in 6 of 60 sampled complaints

   Complaints describe the oil pressure light coming on intermittently after extended driving, with no noise or other symptoms, and repeat visits that did not resolve it. Others describe radiator hoses bursting repeatedly and coolant loss. Several reports note that technicians replaced hoses or checked the oiling system but could not give a lasting explanation. Reported from about 23,000 to 120,000 miles, usually during or after longer drives.

   4 related service bulletins

   What to check: Inspect radiator and coolant hoses for bulging or cracking, check the coolant level and for residue, and ask whether the oil pressure warning has ever appeared. A cold-start and long test drive can reveal warning lights.

   “On wednesday, october 30, 2008 at approximately 4:45 pm I experienced a sudden vehicle engine stop. This occurred on a residential 4-lane street while traveling in the right hand lane at approximately 30 MPH. The vehicle was a 2001 Saab 95 arc wagon. . The vehicle suddenly started to run rough and then the engine completely shut off. This caused me to have to glide the auto to the right hand side of the road where there was a curb. I thus remained in a lane of traffic with a disabled vehicle. …”

   NHTSA complaint #10247843, filed 2008-11, 101,507 miles

   “At 8:00 pm this evening, I went to dinner. Everything was working normally on my car. At 8:20 pm, twenty minutes later, I start my car and it enters limp-home mode with a blinking check engine light, indicating misfire. Given the way the car was acting, the timing belt has broken. In my research, I have found this motor is a GM l81 motor, 3.0l v6. This motor has also been used in the saturn vue and cadillac catera. According to the NHTSA records, there was a recall on timing belts for the 97-2002 cateras. …”

   Electrical system

   Dashboard display pixels and warning light faults

   • 15 complaints (14%)
   • median 49,000 mi at 4.6 yrs old (14 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2004–2009

   Owners report dead pixels and lines on the SID instrument display, making readings hard to read, along with bulbs burning out repeatedly on headlights, tail lights and brake lights. Some describe interior electrical accessories such as heated seats and climate modules failing, and a few mention the alarm unit under the driver's seat getting wet when air-conditioning drains block. Reported from around 23,000 to 101,500 miles, with no consistent driving condition noted.

   3 related service bulletins

   What to check: With the ignition on, look over the SID display for missing pixels and confirm every warning lamp and bulb works. Ask about water leaks into the footwell or under the driver's seat after rain or AC use.

   “I have a 2001 Saab aero 9-5. I have taken this vehicle into the Saab service department over 15 times trying to fix my problem. My vehicle shuts down while driving and many times will not restart. I have also had many electrical issues with my vehicle including but not limited to the electrical modules for the heat and air conditioning, heated and air conditioned seats not working and many other electrical modules going out.”

   NHTSA complaint #10137693, filed 2005-09, 30,000 miles

   “I own a Saab 9-5 wagon, 2001. When it was only 3000 miles out of warranty, twice the unit (alarm system) failed, presumably because it had gotten wet. Saab says that when the AC drains are blocked, it can back up into the passenger compartment of the vehicle, thus causing damage to the twice unit. When the twice unit fails, it burns out all 5 door lock motors, since it erroneously sends a constant electrical signal to the motors. I see this problem as a major design flaw. …”

   Throttle body and rough-running faults

   Mentioned in 4 of 60 sampled complaints

   A few owners describe loss of power and rough running that a dealer initially addressed by cleaning the throttle body, with the fault returning later. One owner who disassembled the unit described deteriorated wire insulation inside it. In other reports the same symptoms were traced instead to the ignition cassette or a crankshaft position sensor. Reported between about 58,000 and 101,500 miles, often at steady highway speed.

   3 related service bulletins

   What to check: Ask whether the throttle body has been cleaned or replaced and whether intake decarbonizing or fuel system cleaner was recommended. Watch for an erratic idle or hesitation during the test drive.

   NHTSA complaint #10178721, filed 2007-01, 61,198 miles

   “Random engine cutoff when driving, loosing power steering capability at the same time. Most often happened when approaching intersection at the time when car speed was lowered. Happened on multiple days.”

   NHTSA complaint #10246326, filed 2008-10, 80,030 miles

Buying note. These cars are old enough that service history matters more than mileage, so ask for records of ignition cassette replacements, fuel pump line work, and cooling system repairs. A pre-purchase inspection that includes a fault-code scan and a fuel smell check is worth the cost on this model year.
