So car was involved in a small collision but after it being repaired I'm having these problems. I did a visual inspection but could not see anything broken. Any ideas what I need to replace? Collision was on the front passenger side of the vehicle. no other problems otherwise it still drives fine.

rest ecu

or disconnect battery for 10 minutes

I've already reset the ecu. I'm thinking some sensor at the front by the wheel is damaged or perhaps something was disconnected when they worked on the vehicle.

did u try d/c battery for 10 minutes?

that rest everything for me

Those lights are caused by the brake fluid level being low. Top it off and it should clear it. If the fluid level is ok there may be an issue with the sensor.

I'll try to dc the battery. Brake fluid is topped. I'll see if I can get my mechanic to take a look at it. Any suggestions for the speed cluster staying at 0?

check fuses? iono

I'm personally still trying to solve this problem on my coupe. The brake sensors are my next option. Lemme know what you find!

My buddy had the same exact problem on his G35 coupe after he jumped a curb. I'll have to ask what he did.

About 3 months after I bought my 2003.5 G35, I woke up to and had to drive 450km back home in -40 C weather. No biggy right? Well, it turns out that my ABS, SLIP, VDC lights were on, and my speedometer was reading 0, and my odometer was on, but wasn't recording anything.

I took it into the dealership, and they told me I would need to have my ECU replaced as the stock one was "completely fried" for $3400. I posted on here, and a dealership in California told me that it was highway robbery and that the part was only a $700 part. (And I'm completely excluding the dealership not letting me have my car back because it didn't have a working ECU, and treating me like I was 14 even though I was 25 or 26 at the time)

So hopefully you don't have the same issue. My suggestion? Try to find someone with the same model G35 as you, and swapping ECU's if an ECU reset doesn't work.

that will be good.

I went to see my mechanic yesterday and lucky me he had no power so he could not check. He said he thinks it's probably a wire that is damaged or broken but he needs to see before he tells me. I'll have to wait till monday before I'm able to bring it to him.

Honestly I don't think it would be the ECU. To me it sounds like the dealer has no idea what they're talking about. The car drives fine no problems and pulls hard just the way I like it.
So did you end up having the stealership fix your car?

Did you figure out you problem
