Is the BMW IX more reliable than the Mercedes-Benz GLE?

No. The GLE is clearly more reliable. Its standing is good, while the IX's is mixed. Owners reported 18.8 complaints per 10,000 IX sold, against 0.6 for the GLE. The IX reports also center on stalling and unintended acceleration, which are more worrying than most GLE faults.

Which has more recalls, the IX or the GLE?

The GLE has more in total, with 98 recalls across eight model years. The IX has 27 across three model years. The GLE has simply been sold longer, so its total is larger. The IX's recalls include a driver airbag repair that owners say was delayed by parts shortages.

What is the biggest problem with the Mercedes-Benz GLE?

Cylinder head failure is the most expensive. It starts with a check engine light, misfires, and rough idle, and dealers find leaking valve seats or a failed head. Many cases landed near 50,000 miles, past warranty, with quotes from $7,000 to $13,500. Water in the footwells is the most common electrical complaint.

Has the BMW IX had crashes linked to acceleration problems?

Yes. Five of nine vehicle speed control complaints are crash-linked. Owners describe sudden, rapid acceleration at low speed while turning or stopping, ending in a crash through a garage door and into a parked truck. One driver also reported surging with no collision warning or alert.

Which model years should I avoid on each vehicle?

On the GLE, avoid 2020 and 2026, the weakest years, and favor 2019 or 2024. On the IX, 2022 is among the weakest, and 2023 appears on both the strong and weak lists. Whatever the year, confirm all recall work is finished before you buy.

BMW iX vs Mercedes-Benz GLE: Reliability Compared

BMW iX

Mixed

More Reliable

Mercedes-Benz GLE

Good

The Mercedes-Benz GLE comes out well ahead of the BMW IX on reliability. The IX draws far more owner complaints for every car sold. Its reports include stalling, sudden acceleration, and airbag recall repairs stalled by parts shortages. The GLE's main risk is costly engine repair.

How Do the BMW iX and Mercedes-Benz GLE Generations Compare?

Only one generation of the IX exists in the US so far, the I20, which started with the 2022 model year and ran through 2025. A facelift is listed for 2026. Shoppers will mostly see 2022 to 2024 cars, all from the same design, so early faults reported in the first few hundred miles apply across the range. The GLE has a longer history. The third generation, the W166, ran from 2012 to 2019 with a 2016 facelift. The fourth generation, the W167, began in 2020 and ran through 2023, with a facelift for 2024. Used shoppers most often weigh late W166 cars against W167 cars, and the W167 includes the weakest year, 2020.

Verdict

The Mercedes-Benz GLE is more reliable than the BMW iX, scoring 67/100 vs 56/100.

Reliability favors the GLE by a large margin. Owners filed far fewer complaints per vehicle sold, and its standing is good while the IX's is mixed. The IX's problems hit core driving functions: stalling, sudden shutdowns, and unexpected acceleration. The GLE has serious faults too, mainly cylinder head failure and harsh shifting, but they are less frequent per car sold. Its much larger recall total comes from eight model years on the road against three for the IX, so it does not change the ranking.

What Are the Common Problems With the BMW iX and Mercedes-Benz GLE?

Loss of control defines the IX's worst reports. Owners describe stalling while driving, a parking brake that sets itself in traffic, and sudden acceleration at low speed that ended in crashes into a garage door and a parked truck. Five of its nine speed control complaints are crash-linked. Steering shaking and drivetrain faults that leave the car undrivable add to the list. The GLE's trouble is more mechanical and more expensive. Cylinder head failure, water in the footwells, and harsh shifting lead its reports. It also has crash-linked service brake complaints, which the IX does not list among its main problems.

Best years to cross-shop: The 2024 BMW iX scored 60/100 and the 2024 Mercedes-Benz GLE scored 70/100 — the strongest shared model years that have been on the road for at least two years, where available.

Who Should Buy the BMW iX vs the Mercedes-Benz GLE?

Pick the GLE if you want the lower chance of a serious fault. It suits you if you can check service history carefully and budget for out-of-warranty risk, since cylinder head failures often arrived near 50,000 miles with quotes of $7,000 to $13,500. Look at 2019 or 2024, the strongest years. Avoid 2020 and 2026, the weakest. Before buying, ask whether the car has had water in the footwells, rough idle, or harsh shifting. Consider the IX only if you want an electric midsize SUV and accept real risk. Buy it if you can confirm every open recall is done, especially the driver airbag repair, which owners say was held up by parts shortages. Target 2024 or 2023 over 2022. Even so, 2023 shows up among both the stronger and weaker years, so check that specific car closely. Test drive it for screen blackouts, warnings, and steering shake. Do not lease or buy one with an open airbag recall.
