Best way to determine issues with A/C and car jerking forward.

[Sacheltry]

Hello,

I hope this is the right forum and I apologize if I get to lengthy. Here goes...

We bought a new 2013 CX-9. About six few months later I was driving it and a car jumps out and I hit him going about 40 MPH. Totally his fault, fortunately no one was hurt. Insurance paid about $18,000 to have it repaired - it should have been totaled.

Now, during the summer months, when it is very warm, the A/C blows hot air and has a chemical smell. Additionally, on some occasions (even when the a/c is not on) and you are moving slowly, the car will randomly jerk forward - I cannot reproduce it but it definitely happens.

We have been back to the dealer several times to have this fixed (they had the car for over 50 days total), have tried to pursue lemon laws (can't really because of the accident) and now we are stuck with a car that doesn't work properly and will have to take a loss on. Our attorney says to just take the loss and move on.

Frustrated with this and being a a computer developer (but know only basics of cars) I decided to get the OBDLink bluetooth adapter in the hopes of logging something for proof. But I am in over my head with that. It's cool but I don't know what to make of the data.

Do you have any advice on they best way to proceed with this? We actually like (liked) the car and it is beyond upsetting that this happened. Plus the dealership has been nasty and incompetent.

Thank you.

Try wantagh mazda. I first went to great neck but they sold to another person who changed it to a nissan dealership. Then i went to garden city mazda but didn't like them. They seemed to be not too honest. After that i went to wantagh mazda and have been going ever since.

The chemical smell on really hot days is probably anti-freeze. I'd have the dealer look really closely at the heater core.

As for the intermittent lurching I'd suggest trying to get your data logger to capture the TPS (throttle position sensor). It would be interesting to see what the TPS was reporting when one of these lurching events occurs. Even if you can't read the data just make sure your logger has the correct data/time and make a note of the exact time it occurs. Someone who can read the data should be able to go back in the log and see if the TPS recorded a spike in the throttle.
