This vehicle qualified for the Volkswagen Emissions Recall, yet from the start of the recall through 2018 settlement lawsuit dates , no correspondence was sent (by Porsche nor VW). According to all recall regulations, my vehicle should have among the ‘recall’ with the 85K plus others, yet no correspondence was sent (by Porsche nor VW) & now the local Porsche dealership is denying in, According to all recall regulations, even still with the EPA, the vehicle was to receive an initial emissions test, then undergo all related repairs/part replacements before the issue resulted in toxic emissions, NOX sensor failures, & premature problems with the DPF system, leading to thermostat problems & the failure of the diesel turbo. Federal regs mandate that vehicle & vehicle equipment manufacturers comply with Early Warning Reporting requirements, submit to NHTSA copies of their manufacturer communications. & update all communications including warranty, policy extensions & product improvement communication sent to dealers, distributors, owners, purchasers, etc. regarding any defect, failure or malfunction beyond normal deterioration in use, failure of performance, flaw or other unintended deviation from design specifications whether it is safety-related or not. Porsche now says my vehicle never showed the recall, despite court mandates that all affected vehicles will be notified communication failed on the sides of both manufacturers. In 2026, if one possesses an eligible vehicle but never received a "Dieselgate" recall notice, options for financial compensation from the original U.S. settlements stated to be likely limited, & I’m not able to find how to proceed with Volkswagen, but regardless, according to EPA and all vehicle standards, I read my vehicle is still entitled to receive an emissions modification at no cost, and that I should be covered by an extended emissions warranty to address all current & related issues.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2013 Porsche Cayenne E-hybrid Coupe verdict →
