My car's original security alarm goes off randomly without any reason. When parked and locked in a parking lot next to a street, the alarm goes off intermittently. After unlocking using fob, the alarm will turn off and then goes off again in a few minutes. This will go on for hours at a time until it stops for a few days and then reoccurs again! very stressful and frustrating. The mechanic says it's caused by faulty body control module and will cost over $1,000 to fix. I see that many people are having the same issue and have to pay over $1,000 to repair. This faulty reequipment should be recalled so owners can recoup their damage.
The car hesitates to start and while driving jerks at around 20mph. This happened a few times in the last year. When taken to dealer, because they could not reproduce incident, said it can’t be diagnosed. I told them it jerks when accelerating at around 20mph and keeps doing it every time I have to stop at light and go again.
Vehicle began hesitating when starting, but not all of the time. One day after refueling it would not start. Lights on the dashboard flashed and flickered and the keyless start button made a clicking sound, but the vehicle would not start. Vehicle was towed to the nearest mechanic. The next morning the mechanic started the vehicle and found nothing wrong. Mechanic kept the vehicle for a couple days and the problem reoccurred. Vehicle will not start. Computer diagnostics shows the 2018 Acura Rdx control unit part number 38320-tx4-a31 is faulty. This part is backordered and likely will not be available in the near future. The intermittent starting failure poses a safety risk and could leave a driver stranded.
The vehicles adaptive cruise control is unreliable. Guidance system goes haywire and cannot stay on track to destination. Carplay becomes inoperable. Have had tameron eastern shore Honda who sold car to me check problem on multiple occasions and they cannot find problem.
The car kept stalling while I was trying to accelerate on the highway. I pulled over and turned it off and the problem resolved itself.
