1993 Volkswagen Passat Problems

What owners report

Owners of the 1993 Passat most often describe a heater core behind the dashboard that leaks, cracks or ruptures, sending steam and hot coolant into the passenger compartment and fogging the windows. Cooling-system, electrical and brake complaints also come up, and many reports arrive on cars well past 80,000 miles rather than on new vehicles.

1. 1
   Visibility (wipers, defrost, mirrors)

   Heater core leaks or bursts into the cabin

   • 17 complaints (25%)
   • median 107,387 mi at 11.2 yrs old (5 state mileage, few)
   • 3 mention a crash, fire or injury
   • filed 1997–2004

   Complaints describe the heater core behind the dashboard cracking, coming apart at a seam or rupturing, so steam and hot coolant enter the passenger compartment through the vents. Drivers report fogged or filmed windows that block the view, a strong coolant smell, and coolant reaching the floor or the driver's feet. Several say a dealer or shop replaced the heater core; some note the same failure recurred afterward. Sample reports span roughly 88,000 to 160,000 miles, and several describe the failure at low speed, while parking, or shortly after pulling away.

   What to check: Ask whether the heater core has been replaced and when; look for coolant residue, damp carpet or a sweet smell near the dash vents, and check that the windows clear properly with the heater on.

   2 excerpts from owner complaints in NHTSA records

   “While driving at roughly 25 MPH, heater core failed. Interior of vehicle immediately began filling with foul smelling dense smoke, and windows became coated with a film. Driver quickly pulled off the road, which fortunately was easy as we were in a residential neighborhood. Driver and passengers believed the engine was on fire, as the true cause of the failure was not immediately known. We quickly evacuated all 4 passengers, including a 5 year old child who was strapped in a car seat. This was a terrifying experience. …”

   “Driving to airport the temperator indicator light came on, flashing, and the heater core exploded. Interior of the car filled with dense white vapor. I was able to stop the car on the road/shoulder and my wife and I evacuated. Road at the time of incident was basicly clear of other vehicles otherwise it would have been a problem of our survival.”

2. 2
   Electrical system

   Electrical faults: no-start, shorts and window/ignition

   • 23 complaints (34%)
   • median 150,500 mi at 5.1 yrs old (2 state mileage, few)
   • 11 mention a crash, fire or injury
   • filed 1995–2003

   Owners report the car failing to start on repeated attempts, sometimes only starting after moving the steering wheel, with several dealer visits ending as "checks OK." Other complaints describe wiring shorts, a battery-to-dash harness fire, power windows operating on their own until a fuse is pulled, and melted air-conditioning wiring. One owner lists a long record of battery, sensor, harness and control-unit replacements. Reports cover a wide age and mileage range, from low-mileage cars to those past 50,000 miles, and appear as intermittent faults over months.

   What to check: Test-cold starting several times, try every window switch and the ignition, and look for chafed or repaired wiring under the hood and behind the dash.

   2 excerpts from owner complaints in NHTSA records

   “Car fails to start when turning ignition on. Takes repeated attempts. Requires unlocking adjustable steeering wheel and 'thumping' the wheel up and down. Occasionally starts on first attempt, mostly after several thumps. Three times took over 45 minutes to get car started. Dealer replaces starter the first time I took it in for repair. Three more dealer visits have been labeled 'works ok', even though I had to start car for service manager. Came back 'checks ok'. I suspect corrosion of some kind in the ignition wiring. Very frustrating.”

   NHTSA complaint #718791, filed 2000-02

   “The power windows operate by themselves-need to pull fuse to stop this, but then they are not operable at all--this could be extremely dangerous in terms of escape from vehicle, and is very inconvenient from a ventilation stand point. The engine stalls when cornering and braking, creating very dangerous situations. ***dimsii ivoq entry posted after 12/12/02 cut-over to artemis****760759”

   Fuel system

   Fuel smell and leaks near the fuel rail

   Mentioned in 5 of 36 sampled complaints

   Complaints describe a gasoline smell inside or around the car and visible leaking where the fuel hose meets the distribution rail near the engine. Owners link the odor to the hose connection and worry about fire risk. In one report the dealer was aware but the manufacturer said the vehicle did not fall under the recall; another owner reports finding the matching recall after the fact. Mileage in the sample ranges from about 105,000 to 115,000 miles, with leaks noticed while driving or right after starting.

   Recall 92V058000

   What to check: Smell for fuel with the hood open after a cold start and look for damp or cracked hose ends at the rail; ask whether recall 92V058000 was completed.

   2 excerpts from owner complaints in NHTSA records

   “Fuel leakage in the engine compartment and noisy fan motor shaft. Found two recalls referring to these two problems. Never received recall letters from manufacturer.”

   NHTSA complaint #10159058, filed 2006-06, 95,400 miles

   “When getting into the vehicle and driving consumer can smell fumes within the vehicle. When checking out the problem, consumer noticed a fuel leakage coming from the distribution rail near the engine beyound the clamp.”

   Engine cooling

   Cooling fan and radiator problems

   Mentioned in 4 of 36 sampled complaints

   Owners describe a noisy or seized radiator fan motor, burnt fan connectors and damaged wiring, sometimes along with a punctured radiator found after shop work. Complaints also mention overheating, coolant loss and water-pump replacement. One owner reports finding a matching recall for the fan but never receiving notice. Reports cluster on high-mileage cars; the recall covering the fan motor shaft describes wear developing over time rather than at a specific mileage.

   Recall 95V178000

   What to check: With the engine warm, listen for fan noise or grinding and confirm the fan runs; ask whether recall 95V178000 was performed, and check for coolant seepage around the radiator.

   An excerpt from owner complaints in NHTSA records

   “Transmission/heater core/ fan switch and engine cooling t system water pump malfunctioned, causing vehicle to overheat and hesitate. Dealer replaced heater core/water pump etc. Please provide further information.”

   NHTSA complaint #840106, filed 1999-06

Buying note. On a car this old, the heater core and cooling system deserve the closest look, since steam in the cabin is the most common theme in owner reports; also confirm the fan and fuel-hose recalls were done and check the electrical and lighting items on a test drive.
