Dear Doctor: I own a 2006 Chrysler 300C with 28,350 miles. As I pulled away from the gas pump, I slowed down and the car stalled. This had never happened before, but the car started right up and I continued on my way. As I continued, each time I stopped for a traffic sign the car stalled, but started right up. The next event was 3 weeks ago when I went to fill the tank it would not accept fuel. The nozzle kept shutting off, as if I had a full tank (at the time it was 1/4/ full). I tried another pump, and even a different gas station, all with the same results. Had to keep clicking the nozzle to slowly fill the tank. After this fill-up the car had the same stalling problem again, except this time it just cranked and cranked. How should I proceed? -- Skip
Dear Skip: I hear this complaint often on a variety of vehicles. The problem usually lies in the evaporative fuel system. A faulty vent, purge valve or canister are common problems and sometimes can set the "check engine" light. On some rare occasions, the gas fill tube hose can collapse. Whenever I'm working on a vehicle that has this problem my first step is to check Identifix for a history of failures and repairs.
Dear Doctor: I own a 2002 Honda Accord V6 (automatic). I have had all recommended maintenance done at proper intervals. I told the dealer my Accord was leaking (I saw dark wet marks on the pavement where I park every day). After an evaluation I was told the leak was transmission fluid and that it would be difficult to find the exact location (the fluid was running along the suspension parts) and fix without completely replacing the transmission. I had to add a whole quart of Honda ATF to get the dipstick to register at the low mark. Is a transmission replacement "worth it" if I want to keep the car another 10 years, or are there other alternatives? If I replace, should I get a rebuilt, remanufactured, or new one? How much would each type of transmission cost from Honda? -- Chris
Dear Chris: I recommend you get a second opinion from an independent shop. The leak needs to be checked if the transmission requires 1-plus quarts of fluid. It could be a simple axle seal, transmission line or solenoid seal leak. A simple cleaning off of the transmission area is all that is needed to locate the leak. The area and leak problem will determine the cost of repair.
Dear Doctor: I own a 2010 Corvette C6. Can I set the tire sensor monitors without going to a dealer when I change my seasonal and/or race tires? Will the Corvette learn the psi with just using a tire gauge in correct sequence? -- Angela
Dear Angela: Of all automakers, General Motors has the easiest tire monitoring system to reset. You should be able to put the system into the learning mode and then start letting air (approximately 5 pounds). Starting with the left front, right front, right rear and left rear. The horn will beep once, then go to the next tire, and then at the last tire the horn will beep twice. You can now push the ignition key off.
Dear Doctor: I have a 1986 Mercedes 560 SL with just 40,000 miles. When I purchased the car a year ago I noticed on the drive home that the air conditioner worked, however, from some location under the dash water dripped on my foot. This spring the air wasn't cold, so my husband bought a kit and recharged it. It worked well until a month ago. Now hot air blows out of all the vent openings, even when everything is turned off. I would like your opinion before taking it in for service. -- Nancy
Dear Nancy: Your Mercedes is a great classic, but the one problem area is the heating and air conditioning system. You will need to find a technician who is familiar with the car and all of its systems. There also are companies that can rebuild the controller. If you had to add a/c refrigerant, then there must be a leak in the system that will need to be checked. I have a friend who had a similar car with the same condition. I suggested a simple manual water shut off valve in line with the heater hose. This shuts the hot water off and prevents hot air from coming out of the vents.
Dear Doctor: I heard Hyundai has a car that costs over $50,000! Is this true? -- Cherie
Dear Cherie: The 2014 Equus Ultimate at $69,800 is the most expensive Hyundai I have come across. It's a rear-wheel-drive, 429-horsepower 5.0-liter V-8 backed by an 8-speed transmission and 19-inch wheels. The Equus has a super large center display, as well as a large, easy to read dash cluster. LED lighting is featured both in and outside of the car. this Luxury vehicle from Hyundai also has 3-zone climate control, plus rear video display screens, heated and cooled front and rear seating and a heated steering wheel. The list can go on and on. The engine is quick and the transmission shifts silky smooth. There is power to spare, no matter what the speed. -- Junior Damato, Motor Matters
