2017 Honda CR-V: engine knocking or ticking

Filed Jul 31, 2025 · FL

On July 31, 2025, my 2017 Honda CR-V was diagnosed by a certified Honda dealership with complete air conditioning failure. The A/C compressor produced a loud knocking noise and was found to have leaked black debris (burned oil/metal), contaminating the entire system. I was informed the system required full replacement, totaling $4,500. The defect has disabled the ability to cool the vehicle cabin, which poses a risk to drivers with health conditions. It also affects window defogging and visibility, especially in humid, rainy conditions. This matches hundreds of similar complaints and class action lawsuits filed against Honda for known A/C system defects in 2016–2021 CR-V and Civic models. My car is outside the standard compressor warranty, and Honda refuses to provide assistance. This failure should be considered a safety hazard, particularly for individuals who require temperature control for medical reasons.

I purchased a 2017 honda brand new from my local dealer on 9/28/2017 I had the oil changed as required . A few months ago I had a oil change done at the dealer at the same visit they did a fuel injection software upgrade. Since the upgrade my engine runs very rough when first started this never happened be fore the upgrade. The reason for the upgrade was that there was gas getting into the oil causing the oil level to rise which stated in the owners manual can cause engine damage. Today I listened to my engine and the ticking noise is getting much loader than when I purchased the car .iam very concern that there is engine damage its seems that honda is in no hurry at all fixing the problem and when they do its going to be to late and the engine will be ruined

Purchased 2017 honda crv exl with awd in october 2017. Immediately after purchase, there was a loud knocking noise coming from the rear of the vehicle. Vehicle was taken to lia honda in williamsville, ny where I was told "that's just the sound of the fuel pump, turn your radio up." the sound progressively got louder so the vehicle was taken back to lia honda in december 2017. Tech that heard the noise said "it sounded like the vehicle was in a crash, the sound was that bad." vehicle scheduled for repair in jan 2018. Repair was made to vehicle in jan 2018 which included added insulation around gas tank and tightening of the gas tank straps. Noise went away for approximately 1-2 weeks. Noise is now back louder than ever as of feb 2018. Car was taken back to lia honda again and we were told "honda told them not to touch the car" and that they "would not make any repairs to the vehicle." I am concerned there is something wrong with the safety system and it is not being taken seriously by honda or my dealership. I do not feel safe driving the car knowing the gas tank or fuel pump is knocking abnormally. The knocking noise happens all the time but is louder when there is a full tank of gas. The knocking can be heard best from the rear of the vehicle near the gas tank.
