Buick LaCrosse models are generally reliable midsize sedans, with newer 2014–2019 cars scoring better than earlier first-generation years.
The Buick LaCrosse has a quiet cabin, smooth ride, and a long run of model years, so shoppers often ask one simple thing before signing: are buick lacrosse reliable? The answer depends a lot on which generation you pick, how it was maintained, and how you plan to drive it.
This guide walks through real reliability scores, known trouble spots, repair costs, and buying tips. By the end, you’ll know which LaCrosse years are safer bets, which ones deserve extra care, and how to judge a specific car in front of you instead of guessing from the badge alone.
Are Buick LaCrosse Reliable? Ownership Trends By Generation
Across all years, the Buick LaCrosse lands in the “above average to average” range for reliability. Independent data sets that track real repair visits give the LaCrosse a 4.0 out of 5.0 reliability score with an average annual repair cost around the mid-$500s, which places it near the middle of the midsize sedan class for ownership costs.
That overall number hides a split story. Early first-generation cars from the mid-2000s carry more engine and electrical complaints, while later second-generation cars improve sharply. The third-generation LaCrosse, sold from 2017 to 2019, posts strong reliability scores and fewer serious issues when owners keep up with basic maintenance.
- Answer In One Line — Later Buick LaCrosse years tend to be solidly reliable; early years need more screening.
- Data Behind The View — Reliability scores cluster in the low-to-mid-80s and above, with quality ratings in the “great” band for many 2012–2019 models.
- Best Match Drivers — Buyers who want a calm highway cruiser and are willing to hunt for a clean, well-kept car get the best from this sedan.
If you pick the right model year and avoid neglected examples, the LaCrosse behaves like a dependable daily driver rather than a repair shop regular.
Buick Lacrosse Reliability By Year And Generation
Every used LaCrosse on the lot fits into one of three broad groups. Each group has its own reliability pattern, common problems, and “sweet spot” years that tend to draw better owner reviews and fewer big repairs.
Quickly mapping your target car to a generation helps you predict what to check during a test drive and what to ask about in the service history.
| Generation | Model Years | Reliability Snapshot |
|---|---|---|
| First Gen | 2005–2009 | More engine, transmission, and lighting complaints; only buy with strong records. |
| Second Gen (Early) | 2010–2013 | Improved safety and comfort but mixed reports on drivetrain and electronics. |
| Second Gen (Late) | 2014–2016 | Some of the best owner scores when maintained; watch V6 timing and carbon buildup. |
| Third Gen | 2017–2019 | Strong reliability scores, refined ride, and fewer serious issues in most surveys. |
Many reliability studies place 2014–2017 cars among the best LaCrosse years, while early first-generation cars from 2005–2009 show higher problem rates and sit on most “years to avoid” lists. That doesn’t mean every early car is bad, but it does mean you should only buy one that comes with detailed service records and a clean inspection report.
Common Buick Lacrosse Problems And How Often They Appear
Even reliable sedans have weak spots. The LaCrosse is no different: some problems repeat across model years, especially when oil changes stretch too far or transmission service gets skipped. Knowing these trouble areas helps you spot warning signs before you buy.
- Engine Warning Lights And Stalls — Some first-generation and early second-generation cars show check-engine lights, rough idle, or stalls tied to sensors, throttle body issues, or timing wear.
- Transmission Shift Problems — Owners report harsh shifts, slipping, or delayed engagement in certain years, often after fluid neglect or heavy stop-and-go use.
- Lighting And Electrical Quirks — Burned-out low beams, faulty headlight wiring, and body control glitches appear on many complaint charts, especially on older cars.
- Steering And Suspension Wear — Power steering hose leaks, worn tie-rod ends, and noisy strut mounts show up as mileage climbs, much like other midsize sedans.
- Comfort And Cabin Annoyances — Owners praise ride comfort but mention tight trunk openings, limited rear visibility, and occasional infotainment bugs on some years.
On a well-maintained LaCrosse, these issues either never appear or show up as small repairs rather than wallet-draining failures. The risk rises sharply when cars miss fluid changes, run low on oil, or rack up high miles with only bare-minimum service.
Buick Lacrosse Maintenance Costs And Repair Frequency
On paper, the LaCrosse sits near the center of the pack for both repair frequency and cost. One widely used repair-cost database pegs average annual repairs around $569 with about 0.3 unscheduled shop visits per year and a 12% chance that a given fix will be “severe” in cost terms.
Those numbers place the LaCrosse roughly in line with other midsize sedans, and a bit better than many luxury-branded rivals. Put simply, the car doesn’t hide scary ongoing bills if you pick a healthy example and run a normal maintenance schedule.
- Budget For Regular Service — Oil and filter changes, transmission fluid, coolant, brake fluid, and spark plugs keep common LaCrosse issues at bay.
- Respect Fluid Change Intervals — Automatic transmissions and direct-injection engines in these cars respond well to fresh fluid; skipped service often shows up later as shift problems or valve deposits.
- Address Warning Lights Early — A small sensor repair is cheaper than driving with a flashing light until a converter, transmission, or fuel system part fails.
- Use Quality Parts And Fluids — Correct-spec oil, filters, and coolant help keep timing chains, water pumps, and gaskets happy over the long haul.
Owners who treat the LaCrosse like an appliance and delay basic care usually end up in the “expensive” slice of the statistics, while cars with regular service often slide by with only modest repair bills.
How Long Does A Buick Lacrosse Usually Last?
A well-maintained Buick LaCrosse can reach 150,000 to 200,000 miles and beyond, which lines up with most other gas midsize sedans. Many owner reports describe cars that cross the 180,000-mile mark on the original engine and transmission with only routine wear items replaced.
Lifespan depends far more on maintenance discipline and driving style than model badge. Short trips, long oil intervals, and heat cycles on worn coolant all shorten engine life. Highway commuter duty, gentle warm-ups, and timely fluid service extend it.
- Check Real Mileage, Not Just Age — A 10-year-old LaCrosse with 90,000 highway miles can age better than a five-year-old car that spent life in stop-start traffic.
- Review Cold-Start Behavior — Listen for rattles, knocks, or loud ticking at start-up; walk away from anything that sounds harsh or lazy to fire.
- Inspect For Leaks And Rust — Oil on the subframe, coolant streaks, or crusty brake lines suggest years of deferred care that may limit remaining life.
If a Buick LaCrosse feels tight, quiet, and smooth on a mixed test drive and comes with proof of regular maintenance, you can treat a well-priced example as a long-term car rather than a short-term stopgap.
Used Buick Lacrosse Buying Tips For Better Reliability
Buying used always carries some gamble, but you can tilt the odds in your favor. Many shoppers start with the search term are buick lacrosse reliable? and then stop there. The smarter move is to pair that general answer with a careful look at the specific car you’re buying.
This section lays out practical steps that help you avoid problem years, spot hidden issues, and pay a price that fits the car’s true condition.
- Target Strong Model Years — Give extra weight to late second-generation and third-generation cars, especially 2014–2017 and 2017–2019 examples with records.
- Check Recalls And Service History — Ask for printed or digital records that show oil changes, transmission service, and recall work done by a dealer or trusted shop.
- Scan For Engine And Transmission Clues — On the test drive, feel for smooth shifts, listen for whines or clunks, and avoid cars that flare revs between gears.
- Test Every Electrical Feature — Cycle headlights, windows, mirrors, radio, seat controls, and climate settings; electrical faults can drain wallets and patience.
- Book An Independent Inspection — Pay a local mechanic to inspect the car on a lift; a one-time fee is far cheaper than buying into hidden timing, leak, or suspension problems.
If a seller resists an inspection, brushes off persistent warning lights, or refuses to share basic records, treat that as your cue to walk. A clean LaCrosse is not rare, so you don’t need to settle for a suspicious one.

Frequently Asked Questions
Which Buick Lacrosse Years Are Best For Daily Commuting?
Many drivers rate late second-generation and third-generation cars as the most hassle-free for daily use. Look closely at 2014–2017 and 2017–2019 models that show steady maintenance and clean accident histories.
These years blend modern safety gear, good crash scores, and sound reliability numbers, which suits long commutes and highway trips.
Are Buick Lacrosse Models Expensive To Repair Compared With Rivals?
Repair-cost tracking sites place the LaCrosse slightly above mainstream midsize sedans but below many luxury badges. Average annual repairs land around the mid-$500s, with unscheduled shop visits near class norms.
That means ownership costs feel more like a well-equipped mainstream sedan than a high-end European car, as long as you keep up with routine service.
What Mileage Is Too High On A Used Buick Lacrosse?
Mileage alone doesn’t condemn a LaCrosse, but risk rises once you move past 150,000 miles. Around that point, suspensions, steering parts, and some engine seals often move into their second round of wear.
A 160,000-mile car with full records can beat a 90,000-mile car with none, so condition and proof of care matter just as much.
Does The Buick Lacrosse Handle Winter Driving Reliably?
With good all-season or winter tires, many LaCrosse models cope well with snow and cold. Front-wheel drive helps traction, and some versions offer all-wheel drive for added grip in slippery conditions.
Cold-weather owners should watch battery health, keep fresh coolant in the system, and rinse away road salt to protect underbody parts.
Is A Certified Pre-Owned Buick Lacrosse Worth The Premium?
Certified pre-owned (CPO) LaCrosse cars usually come with extended warranty coverage, multi-point inspections, and strict age and mileage caps. That package can cut the odds of buying into hidden engine or electronics issues.
You pay more upfront, but many buyers value the added screening and warranty, especially for higher-tech third-generation models.
Wrapping It Up – Are Buick LaCrosse Reliable?
Viewed across all model years, the Buick LaCrosse lands as a generally reliable, comfortable midsize sedan with a few rough patches in its early run. Later cars, especially 2014 onward, tend to reward owners who keep up with oil, coolant, and transmission service.
If you pair a strong model year with a clean history, judged by records and an independent inspection, a LaCrosse can serve as a calm, durable daily driver rather than a constant project. Take time to check the specific car in front of you, and this sedan can feel like a smart, long-term choice.
