What owners say
2017 Chevy Impala 3.6L engine exhaust leak at the exhaust manifold / turbo charger. Resulting in exhaust fumes leaking driver/passenger area could cause fire and or damage to engine. Checking on the customer review and complaints page on the internet I have a lot of other complaints even to the point one persons wife developed lung cancer possible related to inhaling the exhaust according to her doctor. Who knows but I had a hard time getting my car to pass NC inspection because of the lake, please advise. As I am hard of hearing and didn't know I had this problem until the local NC Inspection station pointed it out all I knew was I could smell it or something. PS the email is that of my local mechanic, as I don't have one or how to even turn a computer on.
The exhaust manifold cracked, took to shop to see if can weld and was told it is connected to the Cadillac converter. This was putting MAJOY exhaust fumes into car. making myself and children sick. at the shop they said this is VERY COMMON and he is not sure WHY no recall has been placed on this and why they wont fix. In the process of saving to get this fix the car rode rough, stalled, exhaust fumes and sensor's went. I replaced and I am now HAVING this issue AGAIN. Chevrolet needs to get this fixed and a recall should be done. Had this car just for a year and I SWEAR once warrenty went EVERYTHING this

Fuel system, gasoline: delivery
- What is wrong
- On certain passenger vehicles equipped with 3800 v6 (l36) engines and certain delphi fuel pressure regulators, the regulators have a much higher than usual rate of fuel leaks. A leak can allow fuel to enter the intake manifold through a vacuum line. If the engine does not start when cranked, the fuel from the leaking regulator and a mistimed spark can cause a backfire.
- Risk
- The backfire can rupture the intake manifold. The rupture of the intake manifold can displace a fuel line, pulling an injector out of place, and causing a fuel leak and possible fire.
- Remedy
- Dealers will install new fuel pressure regulators with improved diaphragms. The recall will be conducted in phased mailings. Phase 1 began on june 30, 2004, and phase 2 began on september 30, 2004.
