Hi Jamie, welcome to the forums!

What type of noise is it?

Is it a clattering sound?

Whining sound?

If it's not a clattering, whining, grinding noise and just sounds like a normal running engine but loud on acceleration, perhaps someone removed the air box intake duct, modified it, or replaced the air box with an aftermarket filter which will make it louder:

View attachment 97860 Thank you for the time you took to post the photos and provide information. It sounds like a car with a bad muffler. That kind of loud. I took it to a muffler shop since posting and the tech listened from the outside of the car while I started it up. He said it sounds like the muffler has a hole in it that he 'can fix'. I am not sure if that will help tho if it is something else. What would you do? He's not a mechanic, more a technician at a muffler shop. Should I have a mechanic look the car over before I have the tech work on it?

 

Welcome to the site! Of course I can't hear your sound but I'll offer my 2c worth based on what you've said.

First, Patriot engines do have loud valves at start-up, and more so when it's cold out. Also, until it's warmed up, Patriot engines will rev a little higher. Depending on the outside temperature that may last for a few miles.

Second, presuming you have the CVT, the engine normally revs high to get you started and the vehicle gradually catches up with the engine speed. Some have said the Patriot engine sounds like a chain-saw.

Friendly advice: again, presuming you have the CVT, the transmission fluid and filters should be changed at least every 50,000 miles. I know what the owners manual says and that is way too long to wait. Don't panic, but if you're at 60,000 and don't know if it's been changed, make it a priority. Don't fall for the old seller's line "All the recommended service has been done," because as I said in the previous sentence, the recommended transmission service interval in the owners manual is frankly wrong.

I'm not trying to scare you! I just want you to be happy with your Patriot and a frequent (happy!) poster on this site. Transmission service is cheap compared to a new transmission. Again, welcome!

If it's really loud exhaust noise, like it doesn't have a muffler, maybe someone tried to cut off the catalytic converter, cut part way through the pipe, but didn't finish the job?

Car sounds loud all of the sudden

Found this at the bottom of my car the other day after I noticed the car started to sound really loud. Not sure how this might have happened, but how would I go about fixing this?

I probably would ask them to show me where the hole in the muffler is before I paid to have it fixed.

Thank you.

 

What Ignatz said, plus I've seen one review where it was compared to some V6 Audi "crossover" that was 50% bigger and probably sold for twice as much, and the guy said "the Patriot sounds like a tractor...the Audi is definitely nicer, but if you're ok with a vehicle that sounds like a tractor, then the Patriot is definitely a viable option as it's cheaper" or something to that effect. Probably got the exact wording wrong, it's been more than ten years, haha.

Either way, the Patriot only has an inline-4 cylinder engine, which provides ample power but not what most people are used to, and revs to get to that power, which again most folks aren't used to. And it makes a bit of noise because it's arguably the last proper Jeep and not some Cadillac or Land Rover type thing, which....you get the idea. In this day and age it seems everybody expects their vehicles to be whisper quiet and all but drive themselves, which the Patriot is thankfully neither. Assuming your Sonata was a newer model, I'd imagine this might be the difference you're noticing. Even my 2003 Impala is quieter than my 2010 Patriot though. Two completely different types of vehicles will not sound or act the same under most if not all circumstances.

 

The engine uses solid lifters on the early years and when cold they can really make a racket. At some point they did change them to hydraulic. I usually let it idle for a minute or two then start driving very gingerly with two feet, one on a little brake pressure as I wind my way out of the neighborhood. Helps it to build some heat quickly and quiet them down before I hit the county roads.

 

. . . then start driving very gingerly with two feet, one on a little brake pressure . . .

How long do your brakes last? Do you buy new pads & rotors during the BOGO sale at the parts store?

 

Thank you for the detailed reply with photos and info. I had a tech at a muffler shop listen since I posted and he said it sounds like a hole in the muffler that he can fix. I am not sure if that will help tho and don't want to pay him to do that and still have noise. So I was thinking maybe have a mechanic look at it first at the Jeep dealership. How would you as a Jeep owner proceed? Pay to have a supposed "hole" fixed (he didn't look at the muffler, just listened to the noise upon start up) or have a mechanic look at it first? I don't want to throw money away if it is something else.

I had what could have been interpreted as a loud exhaust. It was a bad rear wheel bearing. The bearingvshowed no play, but was done for.

 

In sandstones photo of the semi-cut catalyst, i had a rust hole right at the mid pipe to catalytic convertor. And i fixed it by using a patch pipe. 2" id by 2" od. I cut off a little off the catalytic and clamped it in.

Nothing more to ADD the Gents on JP.com gave All the Best Tech Advice as Always... I will say when I purchased mine from my oldest Son I always thought it was loud...But Not After the Radio & Speaker Upgrades / old classic rock (60-70) here cant hear anything with that On

Merry Christmas, Happy Hanukkah & New Year

1. I'm going with the KN air intake! I saw!

 

I bought a 2010 JP with 60K miles. Excellent body, clean interior, good vehicle overall. The engine sounds very loud on it. I had a Hyundai Sonata before
the Jeep so maybe I am just not used to the way the Jeep sounds. Once
I get up to 40 miles per hour it quiets down. But upon start up and initial
driving it sounds very loud. Bought from a reputable dealership. I don’t experience any mechanical problems when driving it. It shifts fine, etc. No. check engine light or anything.

I have had it for about 6 months. Engine was loud from
the start but seems to getting louder.

I already know taking it in to be checked is an option but what I was
hoping for here is anyone who has had a similar situation or has heard of one.

Doing “research” at this point. Any comment welcome. Thanks.

We still drive our 2006 Hyundai Tucson. As far as being being dependable & well engineered vehicle, in the same class as the 2010 Jeep Patriot we have, the Patriot is still sitting with a stack of replacement parts on the front & rear passenger seats. I'm not even concerned with fixing it, since there's always been a problem with that vehicle, once I install these parts on it, some other **** will go wrong. That is how it's been since I got it....

I wish I could say I was extremely high when I bought it, but because I don't smoke pot, I can't. It was just poor judgement on my part & nothing more, for not doing further research on it. Repair-Pal has never steered me wrong, why I didn't go to that site prior to buying the Patriot is beyond me.
Because we owned a 1998 Jeep Cherokee for 10 years, and I found a completely rust-free problem free 1993 Cherokee, which is about to hit 30 years old soon, that I still drive, I assumed that Jeep's Patriot would be a great choice.Chrysler's Jeep Patriot, Compass, Liberty, share lot of the same cheap-ass parts, wiring, all wrapped up with some really poor engineering from Auburn Hills, Michigan....

However after owning this Patriot, I'm beginning to think that the Chrysler Pentastar Logo, on a lot of the vehicles, and also atop of the Chrysler world headquarters in Auburn Hills, it's actually a Satanic Symbol...

Jeep was one of the main reasons Lee A. Iacocca was able to take the failing Chrysler Corporation away from bankruptcy into a continued annual profitability, then being worth putting a $32 Billion Price Tag on it. That was the amount paid when it was sold in 1998 to Daimler Benz.
Speaking of Chrysler,
Here's a bit of information that most folks don't know about Chrysler, unless you are a Die-Hard Collector of Chrysler Memorabilia. Lee Iacocca's long time friend & Ad Executive, Leo Kelmenson, and the Ad Agency ''Kenyon & Eckhardt'', were responsible for all the TV commercial's& other advertisements for Chrysler. So backack when Lee Iacocca was in most of the commercial's. Like the ''If You Can Find A Better Car, Buy It'' also used as a Slogan by Chrysler, or the ''Take The Advantage, The Chrysler Advantage.'', or something like that. So with all that said, there was also an Ad Campaign written for Chrysler's called, ''The Car Buyers Bill of Rights''.
Now let me stop here for a minute. I was in the demolition field for about 30 years. Back in 1991, in Detroit, Chrysler's Glass Plant was on the North-East corner of Wyoming & McGraw, Ford Rd ends at McGraw. But right in front of the Glass Plant was a really old building, well actually building's since there were a lot of additions, which was built (by Albert Kahn) & housed DeSoto. With it's 150 Smoke Stack that had DESOTO painted on the side of the stack, then in the 50's, Chrysler had a 75 foot tall by 60 feet wide ''Billboard'', which Every Ford Executive or Engineer would have to see, everyday on the way to work. So for decades, Chrysler was Literally in your face, Well okay, at least on the minds of anyone driving a vehicle east on either I-94, or Ford Rd each morning. So with that said, during the demolition, I took some of my lunch breaks and stroll through the plant to see what all was inside. One day I opened a door to a room, about 25 feet square, the structural concrete columns were on 25 foot centers. At any rate, inside the room were hundreds of Framed Posters, of many sizes. They were leftover storage that someone at Chrysler was either hiding, or some executive from Highland Park told someone to take those old Iacocca posters over to the Desoto building. One that caught my eye was a 2'x3' framed poster with ''Take The Advantage'' on it. Well I did grab about 5 or 6 different posters, but last June, (2022) I was looking for a frame in the garage to use for a large poster I was putting together for one of my sons. I removed the Backer-Board & put it in my computer/parts storage room. While in there getting one of my Les Paul's out to play, I went to place that backer-board somewhere safe because it was about to fall of a couple boxes I have in there. When I turned the board over, it had a ''Hand Drawn'' picture of Lee A. Iacocca, with the
''Car Buyer's Bill Of Rights'' which was printed by the ad agency I mentioned above. Chrysler never went with the
Bill Of Rights campaign, but rather ''If You Can Find A Better Car, Buy It.'' which was also a TV commercial back in 1982, so yes, this poster that was never used is already 40 years old, and I highly doubt anyone else has one, unless Chrysler's Ad Agency had one of their employee's sitting around and mass producing the ad for Iacocca... If I could ead the poster better, Haven't found any name on it yet & we all know how some artists hide their names on paintings & drawings...
You may not agree with me on the Jeep Patriot, but you gotta agree that this was a cool story & comes with a cool piece of Chrysler Ad Memorabilia.. Take care folks, thanks for reading & I also hope that all of you have a Safe, Family Filled & Very Blesses Holiday, even if yours is almost over with... Dan

I see you're new here. Welcome to the site.

First, a correction: The Chrysler bail-out was in 1980. Jeep was owned by AMC until 1988. I think the real reason Chrysler bought out AMC was to get Jeep. AMC autos were dropped shortly after the merger, and AMGeneral went their own way.

Sorry your Patriot has been such a disappointment. I've had just the opposite experience with a Cherokee and a Patriot. My 1993 Cherokee was such a disaster that I traded it early and drove several GMs until 2008 when my Pontiac dealer dropped Pontiac and went all Mopar. Somebody bought my Cherokee, and my heart goes out to them. With only 24,000 miles, they probably thought they were getting a cherry, but actually it was the pit. When I sold it I even told my GM dealer not to sell it himself -- just send it to auction. I stuck with my dealer's new line of Chrysler products and bought my 2008 Patriot. Granted FCA replaced the tranny twice under warranty, but the emphasis in this sentence is under warranty. Didn't cost me a dime and I got a Chrysler for my first loaner, and a Renegade for my second loaner. No quarrels from me. My 2008 Patriot was otherwise wonderful. We liked it so much we bought a 2014 Patriot that we still have -- 185,000 miles and going strong. I sold my 2008 to a friend and he's still driving it at 315,000 miles.

Like all auto sites, this site attracts lovers and haters. Maybe you'll become a Patriot lover after awhile. Although my 2019 Compass is fine, I'd trade with my Wife anytime. She loves the Patriot and keeps refusing my suggestion.

 

Yup Chrysler is junk. But I only paid 500 for mine so I cant complain.LOL.
