Out of the blue, my car would not start tonight. It's brand new - 2008, and 6000 miles. It's been working wonderfully, but is is dead as a doorknob. Would not even attempt starting. The door light was on, but extremly dim. Something under the hood was making a very meek pathethic sort of whirring noise. I did recently have an oil change, and have gotten the Shift to P message - both seem to have been mentioned in other forum postings where the HiHy does not start, but I did not see anyone posting about the weird noise too. Any ideas?

Replying to: jldavis (Jun 24, 2008 8:18 pm) May I suggest you perform a test of the battery charge. Should be fully charged and between 12 and 12.5 volts. If you cannot start the engine, try a jump start like you would with any other vehicle. Once running measure the battery voltage again, should be more than 12.5 volts, between 13 and 15 would be normal. If this fails, it seems a trip to the dealer is in order. I am beginning to think there is a systematic failure in the charging systems for HH based on what I have been reading in these posts. I have a hard time believing all the people experiencing problems with the battery running down and failing is because the owners have left a light on.

Replying to: rodonnell (Jun 25, 2008 9:58 am) You would think that Toyota would have sprung the 50 cents or so for a circuit to shut off the interior lights after 10 minutes. My last three cars have had this feature. |

We've accumulated 85,000 miles on our 2006 Highlander Hybrid, and I'm wondering what Toyota recommends as the timing belt change interval. Does anyone know? BTW, so for our only failure has been a window lift motor, under warrantee.

Interesting issue. One day a few weeks ago when temp reached 115 in parking lot at work. Drove in to work at 8AM, HH 2006 Limited 2WD, 60,440 mi. Parked in parking lot all day cam out at 4PM to go home thermo in dash said outside ground temp 115. Car started like dream. Drove out of PL made a couple of stops to merge. couple of L&R Turns. Then enroute to freeway entrance accelerated and moved to center lane to pass city bus disgorging passengers. All of sudden warning displays all over, but no bells, saying "hybrid failure, go to service" of words to that effect. Luckily work only 10mins from Toyota Dealer and was able to avoid getting onto freeway and take back road to dealership. Left car running with failure displayed on dash for all to see. Grabbed my serivce writer and then sat down for what turned out to be 2hr wait. End result was diagnosed as ECU failure but part out of stock. Dealer was able to reset/overcome failure mode and let me drive off, thinking part was coming from CA and I could come back in three days to get fix (covered under Hybrid warranty.) Had two appointments canx as part remained out of stock, and then magically delivered. After two hours of work I have had car back now nearly two weeks. Runs like a dream and even the problem I had when travelling at 70mph and feeling car hunt as it tried to maintain steady speed has gone away (even though dealer had "reprogrammed" ECU firmware about three months ago -- and complaint still remained.) Was wondering if others had this problem, especially since ECU was so hard to come by. Either this ECU (failed little so no need for stocks in USA) or (failed a lot and spares across USA were being depleted as a result.) Thoughts, comments? Chuck |

Replying to: gree (May 09, 2009 6:01 pm) By the way, I had it changed at Priority Toyota in Petersburg VA. I was quoted $290.00 for the job over the telephone. When I took it in for the appointment, was questioned by the service writer who thought I had a chain. After verifying it indeed has a belt, was called an hour later by the writer who mentioned the price was quoted wrong because the Hybrid requires much more work. Seems funny to me because there is no serpentine belt or other parts to remove from the front of the engine. The dealer honored the price as quoted. Got a call two hours later informing me the work was completed. Interesting, the Toyota Website and All Data quote 2.7 hours for the belt replacement on the HH. Dealer gave me back the old belt and reported there was no leakage in the seals or in the water pump. |
