Kw T680

Great review. The turbo overspeed code is a warranty code and will not clear without Paccar's approval.

Also one came in my shop last night that had a startling 9.5 MPG indicated on the dash. It had a MX with a 10-speed UltraShift.

 

2015 with mx problems so far , signal light on fender burnt off harness and both lights replaced on warranty ghost codes which don't affect performance or fuel economy just annoying and self clear after 10 hrs of driving . Had a small air leak from the start which became a big air leak which required half the truck to be taken apart to reach valve 1400$ bill not covered by warranty .. Turbo farts like a cummins same style of turbo . Had to get doors and cubby doors re sealed off the hop to stop water intrusion covered by warranty ... Otherwise good fuel economy and power once motor breaks in around 80,000 miles I'm at 125,000 miles now never been towed yet or down for more than a day for warranty or air problem . Overall I'm happy that's all that's gone wrong for a Emmision truck Pulling heavy 80 to 100,000 lbs daily

 

Had a few issues with our 2013, nothing too serious. Over all it's a great truck, no real complaints.

 

Starting in may a 2013 I got a company issued 2014, I trained newbees in it.. Its a little to small inside for that but workable. Had it for approx 170,000 miles. Someone backed into it in a truck stop which put in the shop and I was issued another make.. During that 170000 mpg wasn't less then 7.6 per gal. The fuse blew over and over on a 12 volt plug in. The fuel sending unit for the gauge on the dash on drivers side was replaced. It developed a electrical problem kwnworrh couldn't figure out, in 5 minutes with the key in the off position or taken out and put in your pocket a beep started then it shut down anything electrical in use or not. Lights on the inside, any 12 volt power supplies and whatever.

If the was left in the on position, one click away from starting the motor, the use of cooler, fans laptop etc was back with out any problems.. The drain line for the ac would seal itself off at the tip just enough to back up the water and it would drain inside the cab.. I went through the windshields which I believe has something to with the design they broke to easy

Other then this .. It was alright

 

Amen on windshields, been through a few in two years.

Have been in KW all day trying to get the 103 code problem taken care of, turns out it was a bad sensor but of course the mechanic had to waste several hours trouble shooting per Paccar before they would approve replacing the sensor.

As for the gauges/fault code stuff on the navigation computer, well they have pulled the entire dash along with every inch of wiring and still can't find the reason for it not working. Tried a new head, new screen, new main harness and nada so now waiting on a "specialist" from Paccar/KW to decide what to do.

Can't find the source of water intrusion in the CB compartment so I'm going to get a tube of 100% clear silicone and fix that myself.

 

Good god if I could voice my complaints about Paccar's 'SupportLink' I would not have many favorable things to say.

 

About a year later, how goes everything? Thinking strongly about a t680 when my current lease is up in October.

 

You all crack me up lol. Guys say it has never been in the shop once! BTW their CB and carpet are soaked and another get lots of check codes. But it is a perfect truck!

They sure are pretty when l pass them.

 

One of the cheapest Kenworth's made. Enough said.
