#3838 of 4699 Re: Taking 2007 In. [toyotagal] by tomd Dec 12, 2006 (8:04 am)
Replying to: toyotagal (Dec 12, 2006 6:54 am) From what I've read, the Lexus RX350 which uses the same 3.5L engine is actually quieter and more refined than the RX330 was. I think that in part,it is a function of how much sound insulation they put in. The insulation pad on the firewall (inside the engine compartment) in my Highlander is really not that thick. The pad in my old ES300 was thicker. The vibration could also be a function of the motor mounts which I believe are active control. Keep in mind that some of this might be marketing strategy meaning that Toyota/Lexus might not want to make the HL too quite because it so that the RX still has something to more to offer than the Highlander IMO. My guess is that the new Highlander will be quieter but still not as quiet as the RX350. Replies to this message: toyotagal (Dec 12, 2006 12:43 pm)

Replying to: tomd (Dec 12, 2006 8:04 am) My Consumer Reports Auto Guide for the 07 Highlander notes "SUV is quiet and refined" while for the 07 Lexus RX it notes "very quiet interior". Perhaps all the "quiet" for the Highlander is on the outside? (smile)

I recently had a chance to drive my brother in law's 2007 Lexus with the 3.5 L engine. I compared it to my 2006 Highlander Limited which I bought in June. I can honestly say that I could not detect any difference in ride or quietness in either vehicle. The Lexus may be a little quicker with the bigger engine, but better ride quality was not at all apparent to either of us. I think he expected a noticeable difference in ride or quietness, but to me and him, there was not. Replies to this message: toyotagal (Dec 13, 2006 6:19 am) gencon (Dec 13, 2006 8:55 pm)

Replying to: supersonic45 (Dec 12, 2006 8:04 pm) Thanks for the reassurance, Supersonic45. Your comment will save me about 10K when I get my new wheels in a few months. Some of the recent comments about lesser noise insulation etc. in the Toyota had gotten me a little concerned. Although I have test driven several Highlanders and they seemed quiet relative to other vehicles driven.   Besides I don't want to fall asleep while driving.....................

#3845 of 4699 bearing / driveshaft problem by gencon Dec 13, 2006 (8:55 pm)
Replying to: supersonic45 (Dec 12, 2006 8:04 pm) The problem of Highlander is making noise when reduce speed to full stop (starting from 25m / 10m rangge) decscribed as distant siren noise in previous posts. Mine 06 4wd purchased still have such noise. Anyone new 06 has such issue?

Replying to: tomd (Dec 13, 2006 6:28 am) Tom, I took the car in today. The dealer said there is nothing wrong with it. I filed a complaint on NHTS web site. I have an appt on 1/04/07 with the Regional Toyota Technical Representative. I also have my application for arbitration filled out. This transmission is not safe.

Replying to: garywi (Dec 13, 2006 9:06 pm) Gary,   Did they hear/feel the vibration at ~1850 RPM? How about the resonance when idling? I still don't get why the engine should be so much louder than the previous generation Camry with the same engine.   BTW, when my car is fully warmed up, the temp guage needle is a little shy of the 3:00 position. It's just a hair above the next tick mark down. However, when warming up, it spends quite a long time below that tick mark, about half way between that tick mark and the next lower one. I don't know if this is normal but even on 60 degree days, it is like this. Seems awfully long to fully warm up. I wonder if the thermostat is opening too soon. I hesitate to mention this to them because I'd rather not have them tinkering around if there is no problem. Can you comment?   Thanks
