GUYS,

Just came from my local dealership here in the Philippines. Test drove the EX with the service technician and service advisor. At first trial, all clear. Did a runabout, then boom, smell engulfed the cabin. As many members here have relayed, the smell did come from the back then circulating to the front.

The service advisor and technician quickly checked for any advice as they too were troubled by the strong foul smell. Then, there it is! A TSB FINALLY!!! The service technician told me that it just came out recently, as in December 10th 2012!!! The TSB calls for changing parts in the rear bumper since it is where the exhaust smell apparently comes in or is sucked it during hard acceleration. A total of 5 parts will be replaced as part of the TSB. What parts, the service technician said it has to with the rear HVAC system or vents.

Please post the TSb if someone here has already gotten a hold it. The dealership won't show it to me for proprietary reasons.

Hi gang,

The best course of action is to make appointments at your dealerships so they can get you taken care of. If you haven't already contacted me for an escalation, please send me a PM with your VIN, preferred dealer, mileage, daytime phone number and full name; I'll get your regional customer service manager involved and ensure that you're contacted promptly.

Thanks!

Crystal
