“1992 Toyota 4-runner, 3.0 liter, v-6, 4 wd truck in shop for blown head gasket & possible cracked block. I understand this vehicle has a design flaw which causes head gaskets to blow over and over in spite of so-called gasket fix by Toyota which I had after 50,000 miles. Toyota should make it right to their customers by either fixing the flaw or reimbursing for costs to repair, tow & rent replacement vehicle.”
NHTSA complaint #10135700, filed 2005-09, 145,000 miles“My wife and I own a 1992 4runner. The head gasket in the engine malfunctioned causing oil and water to basically get mixed. We took it to the local Toyota dealer in our area (kendall Toyota in miami florida). We tried to explain to them what is listed on your web site as known defect in our car's model and year. However they refused to acknowledge that. We ended up spending $2896.62 at the dealership shop to fix the engine problem. Considering that problem is a known defect as published on this web site. …”
NHTSA complaint #10023788, filed 2003-06, 92,000 miles“I have a 1992 Toyota 4runner with v6 3vze engine which Toyota knows has a bad head design and head gasket failure. They have a recall for one time only replacement which was doen in 97 at 51k mi. By the previous owner. Last dec. I started having problems and the Toyota dealership did not advise me that I had a blown head gasket. They wanted to change out fuel injectors since it was running rough. The roughness was from coolant leaking into the cylinders. After research I found all this info. Out. At the time I was ignorant as to this problem. …”
NHTSA complaint #10086618, filed 2004-08, 139,000 miles“Mysterious coolant loss, pressurized system found no external leaks. Watched problem for about a month, kept topping up coolant. Driving home last night sudden loss of power on free way temperature spike, almost caused a major accident getting off freeway. Head gasket failure. Towed. Campaign has been done, Toyota dealer will not honor labor or even the part, and it is quite an expensive repair for something that will fail sooner than later. My nissan has over 300,000km on it and never had a problem. Flawed design in head or block.”
NHTSA complaint #10249070, filed 2008-11, 213,000 miles“I have a 1992 4 RUNNER. I purchased it in 1997. I took it in for the recall on the head when I bought it. I now has another problem, on of the cylinder is only producing 20% compression. My mechanic said that it has to do with a problem with the head. Is this covered under the recall also?”
