2019 Honda Civic: adaptive cruise control problems

Filed Oct 24, 2026 · Fuel system · NJ

Vehicle experienced immediate severe engine stalling, power loss, and sudden total engine shut-off while moving in live traffic on the road following the execution of the federal safety agency Recall Campaign MGJ (Low-Pressure Fuel Pump Replacement). The engine stall occurs when mechanical and electrical loads engage, such as the AC compressor or cabin heater at idle and while driving. Diagnostic scan confirms permanent active codes P2187 (System Too Lean at Idle) and P0451 (Fuel Tank Pressure Sensor Performance), indicating fuel starvation from the recalled fuel pump assembly under the rear seat. When the engine sputters or shuts off, an immediate electrical warning cascade triggers across multiple safety systems, including Brake Hold System Problem, Power Steering System (EPS) Problem, and Adaptive Cruise Control (ACC) Problem. Authorized dealership (Joyce Honda) and American Honda Corporate (Case # 166-940-04) refuse to perform a zero-cost inspection and remediation without requiring out-of-pocket diagnostic fees, creating an extreme active road hazard. Video evidence of dashboard failure recorded on-road.

Since April of 2024, my steering has been sticking when making the slightest of turns. It has progressively gotten worse. I initially thought that I needed power steering fluid but that did not correct the issue. This sticky causes my vehicle to veer to the left and right abruptly into other lanes. I am fighting to keep the vehicle straight. I can hear the sticking noise constantly due to the lack of lubrication in the steering gearbox. I am fearful that I may cause an accident and injure myself or others when driving and I would like assistance in having the dealership correct this issue. This issue also causes the sensors for my ABS, Adaptive Cruise control, lane departure etc to malfunction and alarm.

On multiple occasions, at least 10, my automatic braking detector system has engaged when no other cars were in front of me or around me on the road. It has happened while driving in the city at slow speeds, on the highway at 70-80mph, and most recently while going up ramp to merge onto interstate. The automatic brakes will engage causing my car to slightly brake and I then have to accelerate, especially while on the interstate, to keep the car moving or else it could just stop in the middle of the road with a potential to cause a deadly accident. My cruise control no longer works either. I wonder if these issues are synonymous? My safety and the safety of others is definitely at risk with my car randomly braking with no cars in front of me or next to me. The vehicle routinely gets inspected at my Honda dealership every 6-8 months when I get my oil changed and they have not reported any issues. There have been no warnings on the car prior to these incidents happening. This car has no accidents and currently has 30,000 miles. I would estimate the car had about 28,000 miles when the last incident happened while going up the interstate ramp. The braking system malfunction started at the beginning of 2023 from my knowledge.

There have been 3 times that this has happened. The first time I was driving and no car was in front of me. There was a car parked off to the side and my car sensored the car off to the side and the emergency braking system came on. My car slammed on the brakes automatically and I was going 45 mph and the seat belts locked up, while my car dived forward. I had to slam on the gas to avoid someone rear ending me behind me on a busy road. The other two times this happened occurred within 2 days of each other. The first was in broad daylight and my car sensored a shadow on the road, setting off the emergency braking system, making my car automatically brake and locking up the seat belts again. I was going 65 mph on this road as it was an interstate. I had to also slam on the gas to avoid an accident. The third time was 2 days later driving at night with no one around me, and I was on an exit 3 minutes away from my apartment. I’m not sure what set off the emergency braking system this time, as I didn’t see a shadow since it was dark out, but once again, it came on, locking up the seat belts. This time I was going 35 mph. I’m lucky each time I was able to get out of it and avoided an accident but I am truly scared to drive my car as this happens out of the blue when the cruise is not on or whether the cruise control is on.

2019 Honda Civic EX was running normally. Next day I start it up and nearly every warning light on the dash illuminates—no power steering, lane assist, adaptive cruise control, braking system, and more. Car is not drivable. At 39K miles Honda says it’s out of warranty.

The power steering didn't work. There were warning messages displayed for Tire Pressure Monitor Problem, Adaptive Cruise Control Problem, Lane Keeping Assist Problem, Brake System Problem, Brake Hold System Problem, Power Steering System (EPS) Problem, Vehicle Stability Assist (VSA) Problem, Hill Start Assist Problem, Collision Mitigation System Problem, Road Departure Mitigation System Problem when turning the car on. This condition was verified by the dealer on both occurrences. First occurrence was 6/8/21. It was towed to Spreen Honda dealer in Corona, CA. According to the the first invoice dated 6/8/21 for the repair there was "Confirmed fault code for C1420 main torque sensor and sub torque sensor, C1421-14 malfunction to steering angle, confirmed multiple fault codes due to rodent damage to the steering system sub harness chewed thru replaced the steering torque sensor sub harness and calibrated the steering angle sensor, cleared fault code now OK." Same problem occurred 7/8/2021. Taken to Spreen Honda again on 7/9/21. Wire harness again replaced, steering angle sensor replaced and power steering calibration performed. I have the wire harness that was replaced. Service advisor stated this is a problem with Honda wire harnesses because the insulation on the wires is soy based. He has seen it many times, including one customer at Riverside dealer who had rodents eat his wire harness four times while he was working there. Not having operational power steering makes driving the vehicle very difficult and potentially dangerous.
