Hi Guys,

Just want to ask some advise and complain.

Honda City E Spec 2014
Owned for 4 Years up to this month (December 2014)
Renewed my insurance(HIP) from Honda
Serviced two weeks ago (Major Service RM 900+ and changed CVT oil)
Not an expert in cars but have some basic knowledge

Q1: Is there any significant difference in renewing your insurance from other company?

Q2: Is it okay for me to service outside because the service inside Honda service center is expensive compared to outside as most of my colleagues already did so? I am worried about warranty part and left one more year to go until the 5 year warranty over.
Complains:
1. Each time I service every 6 months, seems unnecessary as it wont reach 10K(Average 5-7K) millage.
2. They don't give back any extra black oil that wasn't poured finish and sometimes when I checked the black oil level it's around 70-80% full.
3. Bought their engine oil cleaner and treatment and then I specifically demanded that they don't pour it in except the treatment(As they always say will just pour into the engine when service) but provide me the bottle when completed the service. So, I asked supervise when he gave back my key but he told me sorry that he poured it in when I asked "Where's my engine oil cleaner?". Fine!. Later on I went and pump petrol to full to maximize it and noted a really good millage of 18km/l(maintained until my petrol left 30%) until I pumped air today and noticed that they pumped to 280kpa (WTF!) almost had some accident previously when people do emergency break and my car easily slide to the front but stopped in time because I maintained a distance(Lucky). Normally they never each service they pump to 220kpa only but this time was weird for them to pump to 280kpa.

Q3: My reverse sensor haywire(Starts to beep continuously when shifted to "R" that sounds exactly like near impact and cannot reverse anymore) after the last service a week later. So is it cover under warranty and needed honda to fix it? or I should just get it fixed outside as my colleague told me that it might be a loose cable only?

Q4. Obvious and stupid question but still need to ask. When my car cornering it feels like the car is going to lift up unlike 2 years back(Noted on wear and tear) when it's still new and I've done the standard alignment and balancing but still the same.
Heard some advises such as:
1. install a car balancing bar inside the engine compartment but VSA wont work at intended
2. Change suspension (Pay the price)
3. Get Honda to tighten those lose screws and etc

Complain on the CAR:
Front Passenger door side, produce sound such as pressing door sound onto the body when cornering despite slow or fast speed. Fixed twice at Honda service by changing the rubber at the door and adjust the door (Just adjust but dont know what in detail) but still the same after 2 weeks and then I gave up. The technician suggested that I poured some liquid solution onto the rubber that doesn't makes sense when affect on part only. Anyone who had the issue and fixed it?
