“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.”

“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! …”

“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. …”

“Honda Ridgeline 2006 has considerable hesitation when accelerating from under 10 MPH, especially when turning. I was leaving the parking lot of convenience store rolling at about 5 MPH and then tried to accelerate out into faster moving traffic. Vehicle hesitated for about 3 seconds which put me in a position where cars on the roadway I was entering had to brake. Hesitation is constant and consistent since purchase of the truck. Now I currently have 2000 miles on vehicle. Called Honda and they say it's normal for the system of drive by wire . …”

“Honda Ridgeline 2006 air conditioning lines are located right next to an engine bracket. Over time (3yrs) the aluminum pipe wears out causing the freon to leak out of the system and the compressor to stop working. Parts # 24 & 25 had to be replaced at a cost of 400 usd. The new part seem to be made of a bendable material instead of the rigid original and can be bent out of the way of the bracket.”
