Problems with 2002 Toyota Highlander ENGINE AND ENGINE COOLING

Tl* the contacts owns a 2002 toyota highlander. the contact stated that while driving at various speeds, the vehicle would leak antifreeze and the temperature gauge warning light illuminated. the vehicle was taken to an independent mechanic, who discovered that the motor needed to be replaced. the vehicle was not repaired. the manufacturer was not notified of the failure. the approximate failure mileage was 150,000.

A couple of months ago white smoke emitted from the exhaust pipe. last week, on a trip within 400 miles of my home, the engine and vsc light came on intermittently. i immediately called toyota and was told that the car could stop suddenly and leave us stranded so i made an appt for monday morning. the car rode very rough for the last two hours and it seemed as if it is ready to stall anytime. toyota charged me $ 321.00 for a compression and diagnostics test. toyota found that i had low compression. toyota also offered to take apart my engine for 2667.00 to see if the rings were damaged. i refused the work and picked up my car. we called an engine repair business. the owner knew the make, model and year of my car and asked if we had just hit the 100,000 mile marker. we had. he told us of the oil sludge problem, settlement and faulty aluminum engines. i have researched similar characteristics with the highlander and see that it is a common problem for the 2002 highlander. the sludge situation would only be covered if it was within 8 ...

Vehicle has toyota 2az-fe (2.4 l) 4 cylinder engine. oil & coolant leaking from back of engine. head bolts on main gasket failed. in searching internet, countless other owners have unfortunately experienced the same failure which is due to an inherent design problem by toyota. bolts between gasket and main engine block fail and cannot be repaired or replaced. have to buy and install a new engine. called toyota usa headquarters in torrance, ca. and spoke to them, they said they will do nothing for me. spoke to dylan and the case number is 1111291430. i believe that a recall should be issued and that toyota should assume financial responsibility for these failures, which are obviously due to a design and manufacturing problem of toyota. *kb

I purchased a new 2002 toyota highlander from sierra toyota of lancaster, ca. i have experienced no problems with this vehicle until 25 jan. 2011 when the engine overheated while driving 40mph on city street. i took my vehicle to my mechanic and he informed me of a problem with the 2.4l 4cyl toyota engines in which some of the head bolts become loose/stripped where they attach at the engine block. i called sierra toyota of lancaster and they denied any knowledge of this problem. on further investigation, i discovered that sierra toyota had a specialist servicing one of their vehicles by placing inserts into the stripped holes the very next day. sierra toyota refused to give me any monetary assistance in repairing my vehicle. after researching the bolt problem on the internet, i have found numerous toyota owners with the same engine, that have had the exact same problem with their vehicles. the only fix is either a complete engine replacement or having an expensive anchor-bolt redo. my costs look like to be about $2500, if there is no other damage found due to the over-heating. at this point, i don't even know if the new anchor-bolt system will ...

Some earlier models of toyota's 2az-fe 4 cylinder engine are susceptible to sudden failure and are dangerous. the engine is widely used in toyota's popular camry, highlander, rav4 and scion tc models. toyota needs to accept responsibility and investigate the engine. on 9/11/2010, 2002 toyota highlander's 2az-fe engine failed and left occupants stranded. event took place immediately after exiting the highway. the vehicle's engine sputtered and ceased to function. the vehicle had about 75,000 miles on it. the vehicle was towed to a toyota dealership which reported the following: - oil and coolant leaking from the back of the engine head - hydrocarbon in the coolant - oil severely burnt due to overheating the estimate to open up and repair the engine could run anywhere from $2,000 to $7,500 depending on whether the engine block needed to be replaced. the vehicle had been regularly maintained according to the manufacturer's schedule with all the records to prove it. toyota denied request to investigate and defray costs. while engine was opened by a local mechanic it was discovered that two of the ...

My 2002 toyota highlander v6 broke down on the side of the road. i had it towed to the toyota dealership where they informed me that oil sludge has clogged my engine and i would have to have it replaced to the tune of $6000. i was shocked because i always got my oil changed well before the suggested 7500 mile mark. i did some research online and found out my car was part of a recall and class action suit. they never sent a recall notice. we purchased the car when it was 2 years old. i contacted toyota usa and they confirmed that it was oil sludge but since a was a couple months beyond the class action suit of 8 years. i argued that they never sent us a recall notice. they pretty much said tough luck. i was lucky i was able to get my car to the side of the road safely ( my 5 year old daughter was in the back). i don't feel toyota made enough of an effort to let the customer know of these issues.. i feel they were interested in protecting their reputation above ...

I noticed coolant leaking from underneath the plastic into intake manifold in the rear of the engine. i brought it in for repair and the mechanic said he noticed a large piece of foam rubber between the intake manifold and the engine block and head.the leak was behind the foam piece. the only option to discover the source of this leak was to remove the plastic intake manifold, which the mechanic did. after this was removed, it became obvious that coolant had been leaking a minor amount for quite some time due to build up between the cylinder head and block. the only option left is to remove the head, which requires an extensive disassembly (r and r cylinder head). after loosening the bolts in sequence, he noticed three of the head bolts in the back of the engine were loose. after he removed the head sure enough, one bolt came out with aluminum in the thread thus indicating a stripped bolt. and the other three were loose. he said the only option was to replace the engine block, which will cost about $6000 including shipping/labor. i can not afford this and so had the highlander towed ...

4 cylinder engine blocked warped where head meets block. head bolts were stripped and could not be tightened down. following link describes the problem we encountered with our 2002 highlander which has the same 2.4 ltr 4 cylinder engine as the camry. http://www.tundrasolutions.com/forums/ camry/148454-camry-with-stripped-head-bolts/ all diagnosis and repair of our highlander was done at a toyota dealership in roswell, ga. *tr

In june 2008, i was driving when my engine apparently melted down. it went completely hot. i pulled over and there was what appeared to be coolant pooled under the car. prior to this all scheduled maintenance had been done and there was no indication of any trouble with the car earlier that day. i later took it to my mechanic who said he had never seen anything like that in his life. the engine had literally melted. he then tried to call toyota and got in contact with someone but they couldn't figure out what happened either and was unwilling to deal with it. he said it obviously had to be a factory defect. it cost me a whole new engine. *tr

2004, my highlander was serviced for gel in the valve seals. on april 2, my car was brought to leith toyota because the car made a loud noise after being cranked and the oil light was on. as i drove a couple of miles, all computer lights came on and the car cut off. i was told testing was done and i had oil although it was not being pumped to the engine for some reason. (i have oil changed every 3,000 miles). the next day, i went to check on the progress and the service manager told me they drove the car around and it never cut off and he really did not know what was wrong with it. i decided to take it to another mechanic to find out and 10 miles away, the engine blew up. now, i have no car to drive and i am a single mom that has to work. i feel that the service manager should have been honest with me regarding toyota's past engine defects and to drive my car would be fatal. after having it towed to another toyota dealership to check for oil sludge and requesting that my mechanic be ...

Have regularly maintained my vehicle with all required and suggested toyota maintenance schedules, through the dealership, and with only 68,000 miles, i now have learned i have an oil leak between the motor & transmission. *jb

I have owned a 2002 toyota highlander 4 cylinder, 2wd. my car stalled on the road about tow weeks ago and i had it towed to a toyota dealer. i have taken very good care of my car and can provide some partial paper work of my maintenance. the dealer is telling me that i need a new engine, and my bill will go over $5000.00. it has only 77000 miles and no physical damage to the car (no accidents). i have heard about the oil sludge law suit but it covers only 6 cyl but not 4 cyl. could you please help me out on this issue. thanks. *jb

2002 toyota highlander stall-reduce speed to 1000/2000 rpm and shut off engine during cold/hot weather. *jb

Past couple of months have seen smoke coming out of the tailpipe. sludge has built up and clogged the pvc system and inside of the valve cover causing oil to sit inside and damaged the valve seals. dealer wants to clean the sludge under the valve covers and replace the valve seals - cost of 3,900.00. *nm
