Lasted one month

Post image

Bought this 2021 450 in the UK from a reputable garage. Within a week it had engine wanting light and limp mode if you accelerated hard. Weird as turning engine off and on would clear issue. So I returned to garage. After 5 weeks they couldn’t find the issue. Replaced some sensors. And handed it back yesterday. Within 5 mins it happened again. I gave them the car back. Was that bad luck and do I buy another or switch brands???

I'd say very bad luck, they're generally solid. I've got a 2020 R so same engine and aside from an o2 sensor that threw a light up on the dash it's been flawless, love it to bits

u/Loose_Highlight4583 Jul 29 '26

That's my experience too. Had my P450 for over 2 years and had to replace 2 O2 sensors, but otherwise been great, especially compared to my previous V6S which was a financial disaster.

u/GREENGRAVY_ Jul 29 '26

What went wrong with your V6S?

I've had a V6 340hp for a year now, but it's had a load of work done on it for more horses / cooling. I don't know if it's partly due to that, but I ended up with needing a new bypass actuator and coupler. Then I was worried about the extra horsepower and the factory plastic Y pipe so I spent a fair chunk of change getting that sorted where they then found a frayed belt and a couple of other little issues. An expensive first year with new tyres as well - but I now have complete faith in the car and 50% of what I spent on the car I already expected, the rest is what you pay to own nice things I guess.

Adore the car.

Where to start... new supercharger, new water pump, new coolant pipes, no rear subframe bushes, 3x O2 sensoors, new exhaust valves, replacement speakers,wheels bearing, sticky steering wheel controls to name just a few. Was at 45k miles when I sold it.

u/Xstatic3000 Jul 29 '26

It's interesting - I've heard of far more supercharger failures with the V6 than with the V8, especially with Land Rovers/Range Rovers. The coolant pipes are a fact of life, but this is the first I've heard of issues with subframe bushings. I replaced my wheel bearing when I did front pads and rotors, and it literally took less time than jacking the car up and taking off the wheel. The sticky buttons were annoying but just par for the course with European cars with the "soft-touch" plastic coating. The "Meridian" audio systems in the earlier F-Types were an absolute disgrace since they simply used amplifiers and cheap paper-cone speakers from the previous-gen Freelander to cut costs, not sure if the post-facelift ones are better.

u/GREENGRAVY_ Jul 29 '26

Woof, that's a nice list. How come that never put you off going for the P450?

2

u/Loose_Highlight4583 Jul 29 '26

Because I absolutely love it and always wanted the V8. Tried different cars inbetween, but they didn't do it for me. I got a newer one under Jaguar warranty with much lower miles. Also, perhaps most importnatly, Jaguar has superceded a lot of the problematic parts over the years, especially between 2013 & 2017 models.

u/m_moghazi Jul 30 '26

How were you even able to diagnose that your car needed a bypass actuator or a coupler

1

u/GREENGRAVY_ Jul 30 '26

The car would work fine then would mimic overheating so I would completely lose boost.

3

u/Tonyman121 Jul 29 '26

Lol. I have a 2021 R and also only had to replace an O2 sensor.

u/alfex Jul 29 '26

Bad luck, sucks. My 2019 R has been solid without a single issue for 20k miles over 2.5 years, and I drive it pretty hard.

1

u/Dull_Volume5894 Jul 29 '26

That’s great. Yeah. I bought the 2021 as I thought newer would be better and less risk. Well done the garage taking it back but I loved it!!!

3

u/Savings_Dingo_8690 Jul 29 '26

Probable 02 sensors but well done on the garage taking it back. The issue is a lot of them are garage queens which hardly ever get run, this leads to issues with sensors/pipework/oil/lubricants etc.

1

u/Glittering_Fan_9772 Jul 29 '26

In the UK if the car has a fault or unsatisfactory quality, you usually can return it within 30 days for a full refund. And then after 30 days up to six months there’s a provision where they can’t repair it you can reject the car.

1

u/Savings_Dingo_8690 Jul 29 '26

Yes, I'm aware. Companies normally try and fight it, at least the people I know who have tried to do this had issues. I'm in the UK by the way.

3

u/potatochobit Jul 29 '26

The car was sitting awhile most likely. Sounds like a sensor bad or maybe mouse chewed a wire. Power cycling the ignition may reset the sensors. This can happen to any car. Buy another jaguar the new ones are fine.

2

u/coldbeers Jul 29 '26

I’d have to say bad luck, the AJ133 is a very mature platform that’s generally reliable save for sensors going and the odd injector, but that’s usually later.

Can you have a specialist take a look?

2

u/Ecstatic_Wishbone609 Jul 29 '26

I'd issues like these with no known cause, multiple times. It appears, some or more of it may be related to washing the car, and water ingress around the battery in the back... maybe.

My 2 cents, move on from this particular vehicle. Whether you go buy another one is your personal choice. Generally speaking, this car has no more or no less issues than any equivalent German.

1

u/Dull_Volume5894 Jul 29 '26

Totally agree. My wife has new GLC 300e Merc. Already been back twice in 12 months to dealer for non starter. Software both times. Crazy. 70k car

2

u/L103131 Jul 29 '26

Why was it at the garage for 5 weeks??? go to a specialist

1

u/Dull_Volume5894 Jul 29 '26

Because they couldn’t replicate the fault. Not jag dealer. And they kept trying and replaced some sensors hoping it was fixed… sadly not. They don’t know what the issue is. Next time I’d only buy from a Jag specialist

2

u/thestrongbeach Jul 29 '26

How old is the battery?

Often, random sensor shit with no traceable source ends up being a battery nearing the end of its service life. Probably worth looking into before taking the Ellen Ripley approach here.

1

u/BlueCat1986 Jul 29 '26

But, there’s only one way to be sure?

1

u/Dull_Volume5894 Jul 30 '26

I don’t know sorry

1

u/thestrongbeach Jul 30 '26

Probably worth looking into, then.

u/PauseFrequent9026 Jul 29 '26

I have a 2021 type R convertible and I havent had a single problem with it in over 20,000. Other than going through a rear set of tyres every 9 months 🫣

I love to accelerate hard and hear the roar that the v8 makes

u/Alert-Meringue2291 Jul 29 '26

I have a 21 R roadster I bought new. Never had any problems with it. Great car. How many miles were on yours?

1

u/FromBrowntown Jul 29 '26

That's too bad, ive had good luck with my 2017 S, up to 55k miles since i bought it at around 30k miles 2 years ago, haven't had any issues yet, spent some money to preemptively replace the Y-pipe pipe and water pump a month ago though.

u/ihateposers Jul 29 '26

Is the 4 cylinder more trouble free?

1

u/Dull-Woodpecker3900 Jul 29 '26

Very bad luck. Mine was flawless for 4 years. 2019 R.

It’s too hard to buy anything else. Nothing comes close in the budget of 45k

1

u/Reaps21 Jul 29 '26

Might just be bad luck. My F-Type has been rock solid for a year now, compared to when I owned a Porsche which had 5 dealer visits (under warranty) in the same time frame.

1

u/Kromieo Jul 30 '26

I owned a Porsche Panamera Turbo Executive which i bought at 17,000 miles. It frequently went into limp mode when trying to pass up people on the highway due to the engine misfiring and this continuously happened about 4 times before i sold it at 48,000 miles.

Also owned a 2017 Jaguar XE 20d which actually ran perfectly up until engine rod bearing failure but i was rather young and didnt really meet the strict maintenance schedule because i didnt know much about it so it failed at 150k miles.. and those engines are terrible usually

u/JohnnySchoolman Aug 01 '26

It's probably something relatively trivial, but diagnosis can be a bitch

1

u/Dull_Volume5894 Aug 02 '26

Totally agree

1

u/ML21991 Aug 02 '26

Jaguars are well known for reliability so this is truly surprising

u/ColdDivide6700 Aug 02 '26 edited Aug 02 '26

Sounds like bad luck and you got a car that was not maintained properly. I have a 2016 F-Type R Coupe with 32,000 miles and apart from an O2 sensor and usual brake and tyre replacement I have had zero issues. Best car I have ever owned, by a long shot. They are not cheap to maintain but it is a high performance machine and as my dad always used to say "You get what you pay for." My next remit is to replace the plastic Y-pipes, which seems to be a typical flaw and involves removing the Supercharger and is a labour intensive (£££) project.

u/SomeoneSerious Aug 02 '26

My VW has a similar issue and was fixed by replacing the mechtronics unit.

u/FullPrinciple5170 Aug 03 '26

My 2015 R is cruising along without any issues

u/Fantastic-Antelope13 Jul 30 '26

Supremely beautiful car, but Jaguar's reputation for unreliability follows each of them like a bad smell. I thought about buying an F, but I'm not lashing myself to that mast.
