Selected complaints filed with NHTSA by 1996 Toyota 4Runner owners, lightly cleaned up (personal details are redacted by NHTSA).
Shock absorber completely went threw the frame causing the 4 runner to go size to size while driving. Frame is rusting from inside out. Very very dangerous. The same exact frames on the tacomatacoma got a recall, they replaced them. Why wasnt this recalled on the 4runner? And the seatbelts just pop out of the buckle while your just driving. Something has to happen soon or somebody is gonna get very hurt ,or killed. 1 more thing. I had a wheel pop off also from the ball joint breaking luckily that was in my driveway, luckily I wasn't on the main road I could've killed somebody.
I am the owner of a 1996 Toyota 4runner. The 5vz-fe bi-metal engine suffered a catastrophic failure. According to the the authorized dealer (Toyota 101 of redwood city), the engine overheated which subsequently LED to the aluminum heads to crack around the vales. I am aware that Toyota had a national recall on the head gaskets for the 5vz-fe v6 engines for most model trucks (4runner & tacoma) manufactured in the 1990's.the recall was under the guise of a special service campaign ssc-x01. I believe that the defective head gaskets are the core reason for the catastrophic failure of my 4runner's engine. I contacted Toyota motor sales corp. In san ramon, ca & torrance, ca on numerous occasions complaining of the engine failure. I asked for assistance & good will warranty, but received unsatisfactory service. …
Head gasket blew on 5vz-fe engine. This was exactly 3 years & 53K miles after the Toyota ssc (special service campaign) x01. In which they replaced the faulty head gaskets on my 4runner. Also replaced at the time were the; timing belt, water pump, & thermostat. The truck has had all of it's dealer/manufacturers recommended services and oil changes. Upon tear down the Toyota dealership found that both aluminum heads were cracked between the valves at 2-3 places.
Oil sludge problem. Coolant is leaking and oil sludge is building up within the manifold. It is using 2 to 3 quarts of oil on a monthly basis and smoking will badly when first cranked. Car checked by Toyota dealership and says nothing is wrong with car.
My engine catastropically failed at 71K miles. My vehicle had major maintenance performed by Toyota dealerships. The failure of a connecting rod in my engine endangered my life and those of my wife and son by causing my engine to seize up in traffic. The total time elapsed from when my engine was properly functioning to when we were completely motionless was 45 seconds. We narrowly escaped being hit by large commercial vehicles while I was attempting to get to the road shoulder. Toyota was of no assistance to me in this matter. Since my vehicle was out of the 60K warranty, they were not interested in discussing my concerns. My bill to repair this vehicle exceeded $5100.00. I still posses the failed block and componensts. The Toyota dealership threw away some of the components that I asked them to save (oil pump, etc.). …
My sister also owns a 1996 Toyota 4 runner with almost identical build and the exact same 3.4 l engine and she also had the same head gasket failure on her engine. My engine was impeccably maintained, new oil every 3000 miles etc and still had the same failure. My concern is that I don't see a recall for this listed and since its the only problem that both me and my sister have had on two nearly identical '96 4 runner's, it seems a tad coincidental that we're the only ones having this problem. Thanks, erik hord
Consumer was losing alot of coolant. Vehicle was overheating by the temperature gauge. Also, vehicle missing and hesitating. Consumer was unable to drive vehicle because of the overheating problem. The dealer replaced both cylinder head gasket as part of recall, but it failed again after a year.
While driving the vehicle smoke came from the front engine and there was a fuel smell. Manufacturer said defective head gasket was the cause. Consumer stated if manufacturer was aware of problem, why not notify the consumers.
Consumer notice while traveling exhausts leaking sound coming from the engine. Vehicle was service by dealer technician notice corrosion on the crossover pipe. Please provide further information. Ts
The engine stalls when driving and when approaching stop lights. Approximately a month ago I was crossing three lanes of traffice and it stalled. This vehicle is unsafe and warrants repurchasing.
