09 Grand Marquis LS 65,000 miles. Engine "quits" for about an eyeblink.
Happens once about every 350 miles. Not a misfire nor stumble. No codes. Any ideas?

2009 Mercury Grand Marquis Reviews, Pricing & Specs
Write a review
The 2009 Mercury Grand Marquis fits like a comfortable pair of old slippers, so why throw out what you're used to? Clearly this is Mercury's way of thinking, as the rear-wheel-drive, full-size sedan, essentially a dressed-up version of every police department's favorite Crown Vic, hasn't seen a refresh since 2003. Though it comes well-equipped and with a V8 engine, it rides on an old-school platform and lacks many of the modern features and options found in equally upscale large sedans.
Dropping the base GS trim, the 2009 Grand Marquis comes in only one trim – LS. Under the hood sits a 16-valve, 224-hp, 4.6-liter V8 engine and a 4-speed automatic. With nods to the modern age, a flex fuel version is E85-compatible. While not winning any speed contests, the V8 adequately powers the large sedan from point A to point B. Handling, on the other hand, feels soft and vague, but the car does deliver an overall quiet, noise-free ride. The Grand Marquis prides itself on winning 5-star crash test ratings in all NHTSA categories for 13 years running. Though it lacks stability control, even as an option, it comes standard with dual front-side airbags (with dual stage deployment), passenger airbag cutoff, crash sensors, 4-wheel ABS brakes, and traction control. Standard 16-inch wheels can be replaced with larger 17-inch alloy wheels.
The 2009 Grand Marquis easily fits six passengers in its roomy interior, built on a 114-inch wheelbase. Legroom measures 41.6 inches up front and 38 in the back, with a cavernous 21-cubic-foot trunk. Seats do not split-fold, however. A folding rear armrest doubles as a storage compartment. Power windows, locks, and mirrors, 6-way power front seats, a CD player, leather and wood trim, and wheel-mounted cruise control are all standard, with the option to add a 6-CD changer. The latter is about the only concession to modern technology, as a navigation system and Bluetooth are not offered. For a relatively inexpensive price for a large sedan, the 2009 Grand Marquis fits the bill for consumers wanting a solid, quiet, and roomy ride without the distractions of too many gadgets and buttons.

I didnt know there was 2 different levels of trim for the Grand Marquis LS. I knew there was the GS level, the fleet or commercial level of trim. The one I purchased is the lower level for the LS trim. The actual car is very nice will be a good car, just not equipped like my previous LS.Apr 01, 2022

This car rides like a dream; handles amazingly well, and gets far better mileage than my late-model Mustang does. (On a recent 175-mile road trip, I got an amazing 27.63 actual MPG!). A big plus is the huge trunk, which can carry an unbelievable amount of stuff. Some may say that it's styling is "out of date", and maybe so... but, I find myself choosing this car over driving my Mustang to work over and over again, simply due to the higher level of comfort it gives me while sitting in going-nowhere commuter traffic. I'd recommend this car to anyone who doesn't want something flashy, but who wants good, solid, dependable transportation, with a roomy and comfortable ride.Sep 27, 2010

2009 Grand Marquis wipers stop working when it rains
A similar question was asked on this site 6+ years ago but the discussion solved nothing. Apparently this is a common problem for Grand Marquis and Crown vics. I have a 2009 Mercury Grand Marquis. 67,735 mi on the odometer. Sometimes when it rains, my wipers stop working. The problem usually gets worse if it’s raining good and I’m driving for 20 minutes or more. Sometimes they don’t work on any setting except the fastest setting. Sometimes when the wipers are working, the speed is uneven or changes with each wipe. If they stop all together, to get them to work again I have to pull over, turn off my ignition and then start my car again. Eventually that doesn’t even fix the problem. I replaced the wiper motor only a few months ago because of the same issue. Possibly related: I have a fast left blinker even though all my lights are good and many have been replaced since I bought it. When my wipers are acting up sometimes I hear my locks click even though I haven’t pressed anything. My theory is that it’s not the switch in the car, or the wiper motor. There is a drainage trough that gets clogged with leaves, and its not easy to get to to clear out. So when it rains it overflows, the water seeps into messes up the perfectly good wiper motor which is right next to it. Another theory is that it has something to do with the ground wire. Has anyone else had this problem and fixed it? Does anyone have any suggestions of how I could fix or jerry-rig it? I think if I bring it to a shop they won’t even see the problem (everything goes back to normal once my car dries off) and they might just replace the switch or something and not fix the issue. This is the only major problem with my car but its left me stranded and it’s unsafe enough for me to consider selling... its such a stupid flaw though!
