there is a gas odor that is overwhelming when the truck starts. the gas mix with oil fumes will cause headaches because the odor comes into the vents of the truck and does not stop until after the truck is turned off. when the vehicle is turned off there is a hissing sound in the engine that does not stop until after 15min the engine stays off. There is no overheating but the engine is hotter then most trucks when running.

"takata recall" on my regular daily routine, I tried to turn on my car that it was parked on my driveway. I tried turning my car on when I heard a big pop sound, after that big pop sound a cloud of smoke from the front of the car. When I open the hood of the car I saw that the intake manifold of the car was broken into pieces.

Car suddenly came to a stop while driving on highway...

- Stafford, VA, USA

I just tried to start my Q7 and didn't want to start, the auto starter was going for like 4 seconds, so I return the key to the off position to stop it, and a loud bang and smoke came out the engine compartment, when I check, I saw the smoke coming out the lower part of the intake maniford, it was separated from the main piece, I don't understand why this intake got this useless plastic cover, but I really not sure what could cause this, I took it to the mechanic and apparently it came undone for not aparent reason other than a "bad designed part" this happened when I was starting it on my driveway, but could happen anywhere

Heard a loud "pop" then there was a strong smell of fuel coming from the engine compartments in my 2007 Audi Q7 3.6L fsi while I was driving. I stopped the vehicle and shut off the engine and did some investigation and found the leak was coming from the injector and the fuel rail. The vehicle was in motion on a busy street when this leak occurred. Thankfully a someone noticed and notified me that I was leaking something which turn out to be fuel. I was able to fix the problem with occurred on 01/19/2017 by buying a injector seal kit from the dealer.. unfortunately I had another injector fail on me on 01/28/2017. Did some research and found there's a recall for the 2011-2015 model of the Q7. My wife uses this vehicle for her needs with 4 children inside. This is copied from the recall done with the similar issue in the newer model. NHTSA id: 15V019 safety recall 24ap fuel injection system leak certain 2011-2013 model year S4, S5, A6, A7 & Q7 with 3.0L tfsi engine however, a later analysis concluded if the fuel injector valve is out of position during driving, a leak can occur at the connection between the fuel rail and the injector. Any fuel near an ignition source will be a serious fire risk. Similar recall was started March 10, 2015 for the 2011-2015 models. Dealers will replace the fuel rails and seals. Owners of the Audi S4, S5, Q7, A6, and the Audi A7 can contact Audi at 800-822-2834 and refer to recall number 24ap.

The oil pump bolt vibrated loose causing timing gear and chain to fall out inside engine causing catastrophic engine failure and loss of brakes and power steering. Was in motion on a city street moving with traffic and suddenly the engine silently fails causing loss of power assist breaks and steering. The car is almost silent so I did not realize until I came up to a stop light and needed to brake almost causing a serious accident. If you google "oil pump bolt issues" you will see there are hundreds of passats and Audi 's with 3.6 liter engines manufactured at the same factory with this issue. Most of them failed while the cars were under warranty and were fixed quietly by the dealers. Those of us who were unlucky enough to buy one that has not had the "strengthened bolt' installed or engine failure prior to the warranty are driving ticking time bombs. The big problem for this part is that it is located behind a cover in such a way that the engine needs to be pulled in order to reach it this is an extremely expensive preventative step close to 2 K or more just to check for a bolt. I wish I had known prior to this happening as every place I've spoken to wants 15000 dollars to install another engine. I could have easily been killed if I was going a little faster and needed to stop fast.

My wife and daughter were driving on a busy section of road when the car died. No one was hurt and there was no accident. A police officer provided safety until the tow vehicle came. The issue is a blown engine. There was no indication that the engine was failing and it appears to be a timing chain issue. We have had all required maintenance performed at Audi but it is pass the warranty so I am getting no support from Audi recognizing or admitting to the problem. The following link/forum describes the problem: www.passatworld.com/forums/Volkswagen-passat-B6-discussion/327507-3-6-oil-bolt-failure-reference-material.html this is a design issue that I wish Audi/VW would be held accountable to correct as it puts people in danger on the road as well as costing a significant amount of money to fix.
