'10 G37X coupe Strange warning light problem
I have a 2010 G37X coupe. The other day 4 warning lights came on at the same exact time. The AWD, Slip, VDC OFF and ABS. The car was not acting strange and there was no strange noise so I suspected it was most likely a wheel sensor and continued to my destination. Hours later when I went to drive back home. I started the car and let it idle for a few seconds, the same 4 lights stayed on. When the car drove about 100ft all the lights went off at the same time. This rules out any wheel sensor problems. I drove the car about 3 miles and all 4 lights came back on at the same time. This has happened every time now for the last 5 times i have driven it. Start the car, lights are on, car moves 100ft the lights go out. After 3 or 4 miles the lights come back on and don't go out until the car is shut off and restarted then driven 100ft. Has anyone else had this same problem? It can not be the wheel sensors because they either work or they don't so the lights wouldn't go out after traveling 100ft. And even if it's a 1/1,000,000,000 intermittent problem with a wheel sensor it wouldn't be that consistent that the lights come back on at 3-4 miles after going out.
Sounds like you’re dealing with a system-level fault rather than a basic sensor failure. The pattern you described…lights on at startup, then off after about 100 feet, then returning consistently after 3–4 miles…points to something affecting the ABS/VDC/AWD systems after the car is in motion and warmed up.
Here are a few things to check:
1. Battery and Alternator Health
These systems are sensitive to voltage. If your battery is weak or your alternator isn’t holding a steady charge, it could trigger these warning lights. Test the battery and alternator under load to rule that out.
2. ABS Module or Grounding Issue
A failing ABS module can work fine when cold but throw errors once it heats up. Similarly, a loose or corroded ground near the ABS system can cause intermittent faults.
3. Yaw or Steering Angle Sensor
These sensors control stability and traction systems. If one is out of spec or failing, especially after the car has been moving for a while, it can trip all four lights.
4. Tone Rings or Reluctor Rings
A cracked or dirty tone ring can intermittently cause sensor dropouts, especially once the car warms up or suspension/axle components shift slightly while driving.
5. Use a Scanner That Reads ABS/VDC Codes
Regular OBD2 scanners won’t show these issues. You’ll need a scanner that can read chassis or ABS codes (C0xxx type) to find the real cause.
You’re right to be skeptical about it being a wheel speed sensor, especially with how predictable the lights come and go. This sounds more like a voltage, grounding, or sensor calibration issue than a mechanical failure.
If you can get the car scanned at a shop with the right tools, it’ll likely point you in the right direction.
