Radiator Problems of Toyota RAV4

The contact owns a 2010 Toyota Rav4. The contact stated that while driving at an undisclosed speed, the vehicle made abnormal sounds. The vehicle was taken to the dealer, but the dealer could not duplicate the failure. The vehicle was taken to another dealer, nashville Toyota north (2400 gallatin pike n, madison, TN 37115) and diagnosed that the rear differential coupling was leaking oil, the rear driver's side axle bearing was faulty, and the radiator was leaking. The rear differential coupling, rear driver's side axle bearing, and radiator needed to be replaced. The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure and informed the contact that the vehicle was past the nine-year extended warranty coverage. The failure mileage was 97,900.

We were on the road (on a family vacation). The day that we were coming back the check engine light, the vsc light and the slip warning light came on as we were pulling out of the hotel parking lot. On the way to the dealer, I also felt like the car was misfiring. The dealer found "multiple codes p0304, p0305, p0306, p0356, p1578, c1201. #6 coil malfunctioning. Recommend replace #6 coil pack and recheck. Possible that other coil may fail from the result of #6 coil failing. " #6 coil pack was replaced and the Rav4 has been running fine since. The dealer also said that "typically after one coil goes the others follow shortly after", so I will keep an eye open for that. It is strange since ignition coils have a long life expectancy. I checked on-line and there seems to be a high failure rate with coil pack part # 90919-02251, which is the original part that came with the car. I made sure the part was replaced with the latest revision (90919-a2007) of the new part numbers (90919-a2002, 90919-a2004 or 90919-a2007) that Toyota changed to. It is also interesting that most of the failures happen with #6, #4 and #5 coils (in that order). The failures seem to concentrate around the right front corner, which is close to the radiator (hot fluid) exit. Maybe that is why the later revision part # coil packs have a double metallic screen outside the plastic housing, to protect the assembly.

My 2004 Toyota rav 4 started overheating/smoking while driving at 20 mph in a parking lot. I pulled into a parking space and saw leaking antifreeze and I hoped it was just a hose or the temperature gauge. I ran to the store, bought antifreeze, filled the radiator and was able to get it home. The next day, I drove it to a friends mechanic. The engine is leaking antifreeze due to the engine bolts stripping. Apparently Toyota installed steel bolts into an aluminum block and if the engine heats too much, the bolts strip out, causing the leakage. The shop said the repair will cost me 5k at a dealership and 3. 5k at a private garage. I contacted Toyota in California and their response was: discussion thread response (rob browning) 10/11/2011 06:11 am dear ms. _______________; thank you for contacting Toyota motor sales, u. S.

Car was serviced may 28, 2009, then driven across country, from new york state. About two hours outside of austin, texas, the car began to overheat, was found to be completely empty of coolant. Car brought to Toyota dealership where no radiator or other cooling system leaks were detected, but the head gasket was blown. When they tore down the engine to replace the head gasket, they stated that "the bolts are stripped" and now the engine had to be replaced -- at a cost of $7000 +. The mechanic stated that he had seen other Toyotas with this problem and there might be a TSB out on it -- but it was past warranty and so were "stuck". No one can explain why the bolts would have spontaneously "stripped". The car has been sitting at the dealership for three weeks while we try to figure out what to do with it. The head mechanic says it isn't worth anything but he'll take it off our hands for the cost of the partial repair bill ($600). We're not getting the straight story, Toyota refuses to cover the repair, but there are postings all over the internet with very similar stories, including that Toyota has selectively "participated" in the repairs. There is no TSB for this car apparently -- but there are for cars with the same engine.

Was driving on the freeway when my oil light turned on an seconds later white smoke started coming out of the engine. Had car towed to dealership. After looking at the car the dealership determine that the radiator had cracked due to the sludge in the engine. Said I would need to replace the entire engine. Told them I had a 100,000 mile 5 year warranty. My car had about 85,000 miles on it at the time. Toyota dealership said that they doubted that the warranty people would cover that and they rarely saw people get coverage for sludge in the engine. Reported to warranty people and they told me that my car was "very poorly maintained" and because I did not change oil or maintain my car they would not cover. I told them that I had changed my oil several times since I owned the car. They said I need all receipts. I had a few receipts but not all. Took my car to a private shop and got rebuilt engine. Still have not been able to get car out because I am financially strapped. It costs 3500. 00. Toyota said I would have to pay 8000. 00 for a new engine and 5000. 00 for a used engine. Had to rent car that has cost me 1100. 00. Must take car back because I cannot afford it. Won't have transportation. I am disappointed because one of the reasons I bought a Toyota was because of its reputation for manufacturing dependable, long lasting cars. I am a single mother and have so much on my plate to worry about broken down cars.
