2007 Honda Civic power train problems

“On my 2007 Honda Civic SI sedan, the clutch pedal assembly bracket that mounts it to the firewall broke. This effectively disables the vehicle Wherever You Are. You are unable to shift into any gear to safely get off the road or anything of the sort. The clutch pedal assembly bracket cracked on the left side and made the clutch pedal useless. I had to turn off the car when I stopped in the middle of the road in order to put it into first gear without the clutch and then start the car with first gear engaged in order for it to start and have the ability to drive it off the road. Thank God traffic was light to nonexistent. When I searched forums online I found out that this is a pretty common issue with any 8th gen Civic with the manual transmission.”

“Engine Block Cracked. Coolant all leaked out of water jacket. (concurrent with TSB 10-048) Yes it is available for inspection. Car Over Heated, while traveling at speed. Manufacturer is denying inspection. No warning lamps, or lights.”

“Transmission issue reported and the mechanic was surprised bc the car was running very well and I maintain it all the times. Engine light was on as well as the D was blinking Green at the time. Very Safety concerns when the car does have this issues, the car can’t shift to next speed this could lead to a crash anywhere. Of course people start to get upset due to the car doesn’t run as expected on the road. Mechanic changed the 3rd clutch for the transmission but after one week I h am having the same issue again. Transmission issues are very expensive and needs a very experienced mechanic to take care of it. The issue was confirmed by mechanic and certified mechanic place. I had to tow my car and costed my a lot of money. I will attach the communication with the insurance company.”

“My Civic was diagnosed with a cracked engine block, an issue known by Honda to be problematic, as they issued an extended warranty on the engines that ended in 2018. However, the extension has expired despite the fact that many Honda owners continue to experience this problem (see https://www.8thcivic.com/threads/documenting-cracked-engine-block-for-those-out-of-the-warranty-coverage.609546/page-7). This issue should be considered more serious than just an extended warranty, as an engine leaking coolant could easily overheat and cause serious problems on a road trip, especially in the part of the country I live in (Montana), where summers are hot and dry and wildfires are easily ignited. The Carfax report for the vehicle I own--which I purchased used in September 2021--suggested that this would be the perfect vehicle to buy, with a regular maintenance history and lower-than-usual mileage. No indication at all of an extended warranty or potential issues that I should be aware of. Fortunately a friend discovered the issue when he noticed coolant leaking when he changed a tire for me rather than me discovering it while driving to Colorado or Michigan to visit…”

“While driving my 2007 Honda Civic Hybrid at approximately 5 mph, entering a left hand turn from a complete stop, the passenger side driveshaft broke (i.e., the so-called "CV axle" on my front wheel drive vehicle), and a piece of the driveshaft approximately 8 inches long fell into the roadway with a loud audible clunk. We pulled off to the side of the road and were immediately able to retrieve the broken piece. I still have the broken piece in my possession, and I could mail it to an investigator if desired. Photos of the broken axle piece are also attached, together with a dealer repair invoice which lists the Honda part numbers for the replacement parts (due to an availability issue, the dealer used non-OEM parts to perform the repair, whose part numbers may or may not match the original OEM part numbers). It's clear from inspection that the broken driveshaft was initially covered by an anti-rust coating (portions of the coating are still visibly adhered), however most of this coating wore away and the underlying metal was substantially corroded by salt, which ultimately caused the part to fail. This vehicle has been registered in the state of Massachusetts…”
