Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: 2008 is the first year of the 2nd generation Highlander, & it may be a model year to avoid as Toyota most likely worked out some production quality issues with the new model.

The 2009 Highlander is the has far fewer complaints.

rubber oil line broke rubber oil line broke

Engine began revving upon acceleration from a stop light. Engine warning light came on indicating low oil pressure. Quickly pulled into auto repair shop who found dipstick was dry. They poured oil into engine only to see it leaking out from below passenger side. Prior to this occurring, there had been no evidence of oil leakage at all.

Car was then towed to local toyota dealer. Dealer replaced oil cooler hose 15767-31010 which had failed (see photos) with 15767-31020 (all metal assembly). One of the hoses had developed a small (less than 1 cm leak). Replaced oil and restarted engine. Engine began making tapping sound and dealer recommended full engine replacement. Depending on option, quoted cost was between $7500 for a used toyota engine to $8300 for jarco engine (rebuilt). This occurred in South Carolina while we were vacationing from Maryland. Thankfully, we were not on the highway when the hose burst.

Decided to ship car home on flatbed to have local dealer give second opinion. After lead mechanic and service manager listened to engine, they recommended no additional maintenance. While a slight tapping can be heard with hood open, the tapping noise is not as noticeable now (500 miles later). Service Manager instructed me to check for oil leaks (none so far) and listen for change in engine noises. So far so good, keeping my fingers crossed. Confidence in car definitely shot, not to mention SC dealer....

Some additional information:

The single pipe oil hose was replaced in May 2010 under the SSC 90K recall at 33k miles. That is not the part that failed. This is the dual manifold rubber hose that Toyota has now replaced with an all metallic assembly. As far as I know, this part was never recalled, but there is a TSB 02011-11 available (describes possible oil seepage). If I had been aware of this potential problem with my HL, I would have taken proactive steps to have the part replaced. Toyota realizes that this problem is more serious than simple oil seepage. Otherwise, they wouldn't have completely redesigned the part and removed the rubber hoses. There are numerous posts online with customers detailing the same issue. Owners with the legacy oil cooler hose should consider proactive replacement for piece of mind.

Highlander Limited V6

  • Automatic transmission
  • 61,000 miles

Toyota claimed they had a recall on this rubber oil line in May of 2010, but we didn't get a notice. Had vehicle in the Toyota dealership in Daytona Beach, FL in August of 2010, but no mention of recall.

Toyota replaced the rubber line with a metal line on the 09 Highlander.

Now vehicle has been at Cox Toyota in Burlington, NC for 5 days, and still no answer from Toyota, and no offer of a loaner car.

Who would trust a car which is knocking and will probably cost $$$$ to fix, and don't yet if Toyota will cover.
