Got a CEL on my 3 month old AT4 yesterday. I pinged OnStar and they let me know my truck was throwing a P2297 fault which I confirmed with my Banks iDash. According to the iDash it's an O2 sensor fault, but my understanding is that diesels don’t have O2 sensors and it’s likely associated with the NOX sensor
I made an appointment to bring the truck into the dealer to be checked. The CEL cleared on its own later that day but I decided since I already had the appointment I might as well have the dealer check things out.
Stopped in the dealership this morning, told the service person about the CEL, showed him the report from OnStar and let him know my iDash was showing the same code. He got a bit concerned with that and told me that if the tech believed my after market part caused the fault they might not honor my warranty. I explained the iDash is an OBD2 monitor, and that there’s no way it could cause the fault. He responded that would be up to the tech.
An hour or so later they let me know my truck was ready. The confirmed the P2297 code in history, but told me GM does not have a service document for that fault. Since the CEL had cleared on its own and I wasn’t having any performance issues with the truck, there wasn’t anything more to be done. Their recommendation keep an eye on it and if you get another CEL come back in. I know from reading the forums that sensor glitches are not uncommon, so I was OK with that recommendation.
The service person reiterated his concern with the Banks iDash, saying I should remove it until my warranty is up or risk having it voided. I came back with it’s a monitor not a tunner why would that void my warranty. He explained that GM might request pictures of the vehicle and if they saw the iDash they could void the warranty. He also added the following note to my service document.
Advise leaving any aftermarket products, even “monitoring” ones off until out of warranty. ANY aftermarket device can potentially void the manufacturer's warranty.
Nice enough guy, and to his credit just looking out for my best interest, but I still can't see GM voiding a warranty for an OBDC monitor.
I IM’d Banks later that day to ask if they knew of any warranties voided due to the iDash and a rep called me back a short time later to find out what was going on. He told me he only knew of one instance where a dealer had threatened this but that Banks tech support called the dealer and clarified what the iDash can and cannot do. The dealer was apparently satisfied and dropped there concerns with the warranty.
I know legally I’d be able to fight it if they did try to void my warranty but I’d prefer to keep lawyers out of the picture. Just wondering if anyone has had a similar experience.
