2021 Honda Passport engine problems

“I was at a traffic light, when the light turned green I gave the car gas it hesitated, then went into neutral, the battery sign showed on the dash, the car would not go. I was 1 line under half a tank of gas, so I wasn’t empty. Also, just before this happened the radio became full of static on an FM channel. It wouldn’t allow me to switch to park to try and restart it. Scary and Frustrating!!!”

“The vehicle experienced a sudden internal mechanical failure while driving, resulting in loss of propulsion and complete engine failure. The vehicle was towed to an authorized franchised dealership service center (Gardena Honda) for inspection. No check engine lights, warning lights or any pile pressure warning! Oil change was 2,500 miles until next service. Upon complete teardown and diagnostic inspection, factory-certified technicians confirmed internal engine damage, specifically connecting rod bearing failure leading to a seized engine requiring a complete engine replacement ($9,375.00 total repair cost). This internal failure presents a severe safety hazard: an unexpected engine stall or lockup at highway speeds risks loss of power steering, loss of power brakes, and an immediate crash. Symptoms align directly with NHTSA Recall 23V-751 and ongoing federal investigations regarding Honda 3.5L V6 engine connecting rod bearing failures, where out-of-spec manufacturing leads to premature bearing wear and sudden engine seizure. The vehicle is maintained according to manufacturer specifications and has 55,649 miles. The failed components remain preserved at the…”

“Failed engine rod bearing, And a full engine replacement is needed. As I was driving it completely lost acceleration power and became difficult to manage. The dealer verified the issue. All the warning lights including engine flashed on and off as the vehicle lost acceleration power.”

“This is related to service bulletin, 23–010 Honda will not fix my vehicle under the extended warranty unless the problem is replicated while they are doing a performance test”

“There is a known issue with auto idle feature. If you do not manually turn off every time it stays on and occasionally will cause car issue when stopping. I have had it happen in vehicle about a dozen times. When you fully depress brake engine is suppose to i gel to save gas however on occasion the vehicle will completely stall out. I have had this issue happen when approaching stop signs or in traffic situations. The biggest problem is trying to reengage car. Sometimes you can feel it starting to do this and if you quickly apply gas you can avoid it however sometimes the car will lock up with display lights and you have to keep pushing the Engine stop button to turn off the vehicle and turn vehicle back on. It is sometimes difficult to even turn off engine vehicle when this happens but seems to be only way to get vehicle to respond. I have had vehicles behind me almost hit me while I try to get vehicle out of this mode. I know it’s an issue as it’s all over the forums when you search for fix.”

“The engine experienced a catastrophic lower-end bearing failure at approximately 63,000 miles. The vehicle had been maintained according to the manufacturer's recommended maintenance schedule at the dealership service department. There were no missed oil changes. The failure occurred without any prior indication that a major internal engine problem was developing. The vehicle was taken to a Honda dealership, where the engine was disassembled. The dealer confirmed a lower-end bearing failure and reported significant metal debris inside the engine. The engine was determined to require complete replacement. A sudden internal engine failure creates the risk of an unexpected loss of power while driving, which can increase the risk of a crash, especially in traffic or at highway speeds. The failed engine is available for inspection through the servicing dealership if requested. The failure has been confirmed by the Honda dealership. No warning lamps or messages provided sufficient advance notice to prevent the failure beyond symptoms associated with the engine failure itself. I am submitting this report because I believe this may represent a manufacturing or design…”
