1993 Toyota 4RUNNER Problems

What owners report

Owners of the 1993 Toyota 4Runner most often describe head gaskets that fail, sometimes again after a repair, with coolant leaks or overheating. Other reports include a steering relay rod recall with repair or parts delays, fuel leaks, and steering wheel vibration, especially when braking. Where mileage is given, the head gasket complaints involve high mileage, and many complaints were filed in the early 2000s.

1. 1
   Engine cooling

   Head gasket failures, sometimes repeated after repair

   • 17 complaints (33%)
   • median 150,000 mi at 14.3 yrs old (3 state mileage, few)
   • filed 1996–2008

   Owners describe head gaskets blowing, with white smoke, overheating, or coolant leaking into the oil in some complaints. Some report the gasket failing again soon after a repair, and some describe several replacements over the years, with the manufacturer paying for only some of them. Some say the dealer or manufacturer did not assist, or that a recall or special service campaign was done but the problem returned. Where mileage is listed, it ranges from about 127,000 to 187,000 miles, and these complaints were filed between 1999 and 2008.

   What to check: Ask whether any head gasket work has been done, and request the repair records and any campaign or recall applied to the VIN. Ask a technician to check the oil and coolant for signs of mixing, since some complaints describe coolant leaking into the oil.

   2 excerpts from owner complaints in NHTSA records

   “I own a 1993 Toyota 4RUNNER 3.0 l with approximately 150k miles on it. About a week ago, I was driving home from work and my head gasket blew causing the engine to seize. I was stuck on the 395n in washington, dc in the cold for 3 hours before the tow truck came with my 1 year old son. I did some research and found out that the 3.0 engines had a recall on it for the head gaskets back in 1996. I called Toyota and gave them my VIN only to find out that my car isn't eligible. …”

   NHTSA complaint #10112763, filed 2005-03, 150,000 miles

   “My 1993 Toyota 4-runner has gone through four head gaskets in the last seven years. And now it needs a fifth! Toyota actually replaced the first two at no cost. Toyota had issued a recall on the head gasket (though I received no notification of the recall even though I purchased this vehicle new from the dealer). So the first head gasket was replaced at no charge, then it failed within nine months, so they paid for the second. But they have not paid for the third, forth, nor now not the fifth.”

   Steering

   Steering relay rod failure and recall repair delays

   • 6 complaints (12%)
   • median 129,766 mi at 13.7 yrs old (2 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2005–2007

   Some owners describe the steering relay rod falling off after striking a pothole, which required forceful steering to pull over. Others say recall parts were unavailable at the local dealer, that the manufacturer had to analyze the situation before any response, and that they could not reach a dealer. Some seek reimbursement, and a complaint includes a FOIA request for information on the steering notice. Where mileage is listed, it ranges from 79,532 to 180,000 miles, and these complaints were filed between 2005 and 2007.

   Recall 05V389000

   What to check: Check the VIN on the recall lookup for recall 05V389000, and ask the dealer to confirm in writing whether the steering relay rod part is in stock. Ask for proof that the steering relay rod work was completed, since some complaints describe repairs being delayed or reimbursement requests going unanswered.

   Fuel system

   Fuel leak or vehicle fire reported

   • 9 complaints (18%)
   • median 185,000 mi at 18.2 yrs old (3 state mileage, few)
   • 2 mention a crash, fire or injury
   • filed 1997–2018

   Owners describe fuel leaking from a failed pressure damper or injector valve onto hot engine or exhaust parts, sometimes with a fuel odor entering the cabin. Some describe a fuel line leak that led to an engine fire, and another describes an engine that shut off, smoked, and then the vehicle burned. A complaint says online forum posts describe fires from the same failure. Where mileage is listed, it ranges from 123,800 to 200,000 miles, and the complaints were filed across a wide span of years.

   What to check: Ask a technician to inspect the fuel pressure damper, fuel rail, and fuel lines for leaks, and ask whether any fuel leak has been recorded for the VIN. Check the engine bay and exhaust area for fuel smell or residue during a walk-around before buying.

   2 excerpts from owner complaints in NHTSA records

   “Fuel pressure damper failed spilling fuel onto exhaust crossover. I had an odor of fuel coming from vehicle for approximately 1 month. Unable to locate issue. Fuel smell would also come through the A/C into the cabin. Upon researching the issue, I came across many forum threads with owners complaining of this issue. This is a known issue and many fires have started due to this failure. Clues to failure are erratic RPM due to loss of fuel pressure and strong odor of fuel coming from engine compartment. Many owner complaints on forum threads. …”

   NHTSA complaint #11083477, filed 2018-04, 200,000 miles

   Brakes

   Steering wheel or car vibrates, often when braking

   • 5 complaints (10%)
   • median 181,240 mi at 15.3 yrs old (1 states mileage, few)
   • 1 mention a crash, fire or injury
   • filed 1996–2008

   Owners describe the steering wheel vibrating, often when stopping, and some link it to rotors or brake parts that needed replacing or resurfacing. Some say the wheels were out of round when the car was bought, which made the tires jump and the rear brakes lock. A complaint after a crash describes uncontrollable steering wheel vibration at speed, and the dealer said the alignment had been done improperly. Mileage is listed in only some of these complaints, where it is about 181,000 miles after a crash, and the complaints were filed between 1996 and 2008.

   What to check: Ask whether the rotors, brake pads, or wheels have been checked or replaced, and ask for alignment records if the car has been in a crash. Ask a technician to check wheel roundness and balance during a test drive that includes gentle braking from speed.

   “Consumer states that the effectiveness of the brakes are wearing. When coming to a stop, the steering wheel vibrates and it takes longer to stop. The dealer has repaired two times for the same problem. There is a TSB out for this problem.”

   NHTSA complaint #816430, filed 1997-09

   “Wheels were bent when vehicle was purchased, defect in roundness of rim. The center of the rim is not in the true center, causing tires to jump/lose contactwith road surface, allowing rear wheel brakes to lock up.”

   NHTSA complaint #807991, filed 1997-02

Buying note. When considering this model year, ask for proof that any head gasket or steering relay rod recall work was completed, and check the VIN on the recall lookup. Also ask a technician to check the fuel lines and pressure damper for leaks and to look for signs of coolant in the oil.
