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.

2006 Honda Ridgeline Owner Comments

problem #6

May 082012


  • 105,000 miles


The contact owns a 2006 Honda Ridgeline. The contact stated that the hose that connected from the radiator to the engine became disconnected, causing oil to drain from the engine. As a result, the vehicle could be started but could not be moved. The vehicle was towed to a mechanic where the contact was awaiting a diagnosis of the failure. The failure and the current mileages were 105,000.

Ridgeline 6-cyl

  • 93,528 miles
We love our Honda's (3 other), I was so excited about my purchase of a Ridgeline from a la dealership in Dec 2006. My nephew purchased it from Honda finance directly and shipped it to Utah for me and I have meticulously cared for and loved my Ridgeline! in December at 93,460 miles my truck lost its perfect harmony... it began putting out white/blue smoke. I had an incident where the accelerator took off and I had to shift down and brake real hard to gain control of the speed. I was traveling South on I-15 through salt lake county at the time, speed around 65 mph. Very scary! soon after the "check engine" light came on and when I idled it flashed. I was told that this is probably the moment that the cylinder "blew out". I took it in and was told that my #4 spark plug was "gummed" up and needed replacement, it was suggested that because of the increased mileage I should do a full valve replacement. $785 later, the smoke exhaust was the same and 3 weeks later the light came back on. I took it back and they "scoped" the cylinders and found #4 had "pouck" marks and had lost compression. I needed a new engine. I called 5 auto shops in my general area and found that 2 of them had seen the same issue with a 2006 ridgelne and a 2007 Pilot. Both mechanics told me that the owners had taken them to Honda dealerships & Honda had replaced their engines, they "were under 100,000 miles". I did so, $97 later I was told that "no. Honda had deemed my situation not worthy of a warranty." What?! I can't even trade it in to a Honda dealership to purchase a new one without the $5K reduction in value! I have a history of timely and meticulous care with my local Honda dealership and a mechanic shop, this is not what I expected from Honda! you must have an issue if in my little suburb 2 others have had #4 cylinders go bad just before 100,000 miles.

I was leaking engine coolant so I went to the dealership to get it checked. I figured that while the truck was at the dealer I should get the check engine light that keeps going on and off looked at. Turns out my radiator had blown and the valves in my engine were too tight and they needed to be adjusted. It cost me 800 for the radiator plus 400 for the valves and I've noticed a huge gain in my gas mileage.

  • 88,000 miles
On or about January 9th, 2010, I started my 2006 Ridgeline to and turned the heat on high to warm it up before leaving my home. When I returned to the vehicle to leave, the entire cab was filled with smoke. My husband located the source of the smoke, coming from under the dash on the passenger side. He found wires sticking out and determined that they were burnt and that we needed to bring the vehicle to the dealership for repair. The vehicle was taken to our local Honda dealership and partially repaired. The cost was $451.71. Still, the high low fan switch / knob does not always respond. Occasionally, when the control switch is in the "fan high" position, the fan will cut off. The dealer advised it will be an additional $400 for the new switch, not including labor.
