Been lurking here for a while. Finally decided to register. Hope you will allow me to vent.... My 06 Taco has had the ticking engine since 7500 miles. (just turned 30K) It's been in and out of Toyota dealers so many times I lost count. First time I mentioned it at 7.5k dealer took it right in and replaced exhaust headers, nothing changed. I've been through Toyota Motor Sales, with two different case numbers/case managers. TMS and the dealers just keep telling me "it's a known problem, don't worry about it." or "all of them do it". I know 8 guys who have the same truck and theirs don't do it. The ticking worries the hell out of me. An engine should not sound like that! Everytime I pull into a drive thru or into the parking garage I hear it. It's driving me crazy. (they're coming to take me away, haha hehe) What bugs me the most is they (TMS) will never say exactly what causes the ticking. It feels like they are just dragging me along untill the warranty is up. Case manager slipped up one time and quoted a much higher mileage in an effort to blow me off, saying it was out of warranty. I think TMS is at their wits end with me because I've been persistent. Their final option now is to offer to go to arbitration to buy the truck back. Anyone gone this route? What was the outcome? (I know it can't possibly be in my favor) Anyone got one of these engines with a 100k miles or more on it who can say it really has not been a problem? I'm just distraught. This was my dream truck and I planned to run her to well over 150k. With life and raising kids I have not purchased a new truck since 89. I've owned 9 different Toyotas since my first in 89. And run them all to over 130k, and never had these type of problems. Any input is appreciated.
