1995 Pontiac Sunfire Problems

What owners report

Owners of this model year most often describe coolant loss and engine overheating traced to the cylinder head gasket, frequently repaired more than once. Electrical complaints are the second theme, with ignition switch heat and smoke reported before the switch recall, plus failures of alternators, lights and blower fans. Most reports in the sample come in between roughly 50,000 and 115,000 miles.

1. 1
   Engine cooling

   Head gasket coolant leak and repeated replacements

   • 28 complaints (24%)
   • median 84,500 mi at 8.3 yrs old (5 state mileage, few)
   • filed 1998–2004

   Complaints describe coolant loss, an illuminated coolant or low-coolant light, hesitation, white smoke from the exhaust and engine temperature climbing toward hot. Several owners say the head gasket was replaced under warranty or a special policy and then leaked again, and that later repairs were declined as out of warranty. Others report a cracked head or internal engine damage found at the same time. Most sample reports fall between about 12,000 and 115,000 miles, with several owners describing a second or third failure after an earlier repair.

   What to check: Check the coolant reservoir level and look for residue or oil film in the coolant, and ask for receipts showing whether the head gasket has already been replaced and when. A pressure test of the cooling system before purchase is worthwhile.

   2 excerpts from owner complaints in NHTSA records

   “When driving and speed reached 40 MPH the car vibrates, when speed reached 60 MPH it vibrates again. When decelerating after driving for a little while, and speed reached 10 MPH (while decelerating) the car vibrates violently, then shuts off. When I restart the engine it runs noisily while still in park, then shuts off again when put in gear. I have to wait a minute or two before I start the car and put it in gear and it runs, until I decelerate again and the cycle starts over. …”

   NHTSA complaint #10005100, filed 2003-02, 90,000 miles

   “For more than a year my car has completely shut down. Fuses blow. I've had head gasket replaced, 2 clutches installed, and a new ignition module. Various other small problems. Mechanic does not know what to repair next. The most recent shut down occured on highway during rush hour traffic. Was towed home. Now sitting in driveway.”

   Electrical system

   Ignition switch heat, smoke and steering column fire

   • 15 complaints (13%)
   • median 157,000 mi at 13.5 yrs old (1 states mileage, few)
   • 10 mention a crash, fire or injury
   • filed 1998–2008

   Owners describe difficulty turning the key or starting the engine, a grinding or strange noise at the ignition, and smoke or flames from the steering column area, sometimes with the vehicle parked and switched off. Complaints also mention melted column parts and dash components, and that the ignition switch recall repair was delayed by parts availability or not performed correctly. Reports in the sample span a wide mileage range, from very low mileage to about 157,000 miles, and several describe the fire occurring with the vehicle parked.

   Recall 02V070000

   What to check: Ask whether recall 02V070000 for the ignition switch was completed and keep the paperwork; also check that the key turns smoothly and that no burning smell or melted plastic is present around the column.

   “Strange noise came from ignition when vehicle was cranked. Engine continued to run after ignition was switched off. After several attempts to switch off, the engine shut down and smoke came from the ignition area. Smoking stopped, but later vehicle was found with the interior engulfed inflames.”

   NHTSA complaint #531829, filed 1998-03

   “Key was not in the ignition when the horn started to blow on its own . Also, within minutes consumer noticed flames coming out of steering column. Prior to this incident ,consumer had tried to start vehicle, but ignition did not turn over, and heard a grinding noise.vehicle was a total loss.”

3. 3
   Brakes

   ABS noise, warning light and inconsistent braking

   • 17 complaints (14%)
   • median 100,000 mi at 9.6 yrs old (3 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 1995–2010

   Complaints describe ABS pump or motor noise when the brakes are not applied, the ABS warning light coming on, a clunking or pulsating pedal, and the brakes grabbing and releasing so stopping distance increases. Some owners report the ABS activating when it should not, and dealers variously adjusted the system, replaced the ABS module, or could not find a fault. Most sample reports fall between about 54,000 and 96,000 miles, and a few owners link the behaviour to wet pavement or to rain.

   1 related service bulletin

   What to check: Ask whether the ABS module or pump has been replaced, and test the brakes on a quiet wet surface if possible; a steady ABS light or pump noise with the pedal released is worth investigating before purchase.

   2 excerpts from owner complaints in NHTSA records

   “We have had this car for about 2 years, and have had problems since the beginning. First thing was the cooling fan. It quit working about 6 months after we bought the car. We had that fixed then started having other electrical problems. The brake lights would work here and there, the turn signals would work one day and not the next, now they don't work at all. The ABS light would flash off and on and the brake light would come on also. …”

   NHTSA complaint #10098031, filed 2004-10, 100,000 miles

   “1995 Pontiac Sunfire rear of car squats when braking I've had the brakes checked / adjusted numerous times NHTSA already has this listed as service bulletin 735018 I would like to add our vehicle to this complaint.”

   NHTSA complaint #10023685, filed 2003-06

   Transmission and drivetrain

   Transmission slip and shift indicator mismatch

   • 5 complaints (4%)
   • median 90,000 mi at 8.3 yrs old (1 states mileage, few)
   • filed 1998–2003

   Owners describe the automatic transmission going into neutral or slipping when it should kick down, such as driving uphill, and revving without moving. Others report the shift indicator showing a position the transaxle is not actually in, and one complaint mentions vibration linked to the torque converter clutch. Reported across the sample from moderate to higher mileage, generally around 90,000 miles and above.

   Recall 96V003000

   What to check: Check that the shift indicator matches the gear actually engaged, and drive the car up a grade to confirm it holds gear without flaring or slipping between shifts.

   2 excerpts from owner complaints in NHTSA records

   “Torque converter clutch failure caused a vibration in the drivetrain from 35mph to 50mph. The dealer suggested disconecting the clutch as the cheapest way to stop the problem. The car has since lost about 3mpg. This was not the right way to fix this problem. The head gasket started leaking around 55,000 miles. A Pontiac service manger told me it would cost about $500.00 to fix the leak,,or I could put some bars leak' in the coolant to seal up the leak. Again this is the cheap way out for a while, but not the correct way to fix the problem. …”

   NHTSA complaint #706792, filed 1999-05

   “Automatic transmission failure. Whle driving uphill vehicle went to kick into overdrive and instead went into neutral wher eengine idled and would rev up but not go into any gear.”

   NHTSA complaint #533284, filed 1998-03
5. 5
   Air bags

   Airbags not deploying in a collision

   • 10 complaints (8%)
   • typically at 3.2 yrs old
   • 7 mention a crash, fire or injury
   • filed 1995–2002

   Complaints describe frontal impacts in which the driver or passenger airbag did not deploy, and in one case deployment occurred a few seconds after impact. Occupants report bruises and back injuries, and some owners also mention seat belt concerns in the same incidents. Sample reports cluster in the late 1990s through the early 2000s, and mileages are not recorded for most of them.

   What to check: Ask whether the airbag warning lamp comes on with the key and then goes out, and have the system scanned for stored airbag codes; an illuminated or non-functioning airbag lamp deserves attention.

   2 excerpts from owner complaints in NHTSA records

   “Consumer has been experiencing problems with driver's and passenger's side air bags. During a front end collision, air bags failed to deploy. As a result, the consumer was bruised very badly. The manufacturer has yet to be contacted.”

   NHTSA complaint #834406, filed 1999-02

   “Accident at 11:30 position at 35-40mph drivers shoulder belt did not hold and hit her face on steering wheel seatback flew forward and driver airbag delayed. Tt the seat belt was a two point type. The driver suffered some injuries.”

   NHTSA complaint #973120, filed 1995-10

Buying note. On a car of this age the head gasket and cooling system history matters most, so ask for service records and expect to budget for cooling system work. Also confirm whether the ignition switch recall was completed and have the brakes and airbag system checked by a mechanic before buying.
